Final answer:
To determine the maximum number of days Jim can rent a car, set up the inequality 21d + 25 ≤ 115. Solving for 'd', Jim can rent a car for a maximum of 4 days.
Explanation:
To determine the maximum number of days that Jim can rent a car, we need to set up an inequality using the given information. Let's denote the number of days as 'd'. The rental cost per day is $21, so the total cost for 'd' days would be 21d. The cost for the miles driven is $0.10 per mile, and Jim will travel 250 miles. So the cost for the miles driven would be 0.10 * 250 = $25. Now, we can set up the inequality:
21d + 25 ≤ 115
To solve for 'd', we need to subtract 25 from both sides of the inequality:
21d ≤ 90
Now, divide both sides of the inequality by 21:
d ≤ 90/21
d ≤ 4.29 (approx)
So, Jim can rent a car for a maximum of 4 days.

Answer:
1. 23.55 in
2. 102.36 mm
Step-by-step explanation:
First, the circumference of a circle is written as: [tex]C=\pi d=2\pi r[/tex], where either equivalence works and d = diameter and r = radius.
1. We know that d = 7.5, so we just plug this into the equation:
[tex]C=\pi *7.5=3.14*7.5=23.55[/tex]
Thus, the circumference is 23.55 inches.
2. We know here that r = 16.3, so we can plug this into the other equivalence:
[tex]C=2*\pi *16.3=2*3.14*16.3=102.364[/tex] ≈ [tex]102.36[/tex]
Thus, the circumference is 102.36 millimeters.
Hope this helps!
Answer:
1. 23.55 inches
2. 102.36 millimeters
Step-by-step explanation:
1. Circumference = pi × d
3.14 × 7.5
= 23.55 in
2. Circumference = 2pi × r
2 × 3.15 × 16.3 = 102.364 mm

(2 +9+4)
(3 + 1 + 4 + 8)
Answer:
15 and 16
Step-by-step explanation: To get simplified form, you add the numbers in parentheses together. (2+9+4)= 15 and (3+1+4+8)=16
For problem 1. 2+9=11 11+4=15
For problem 2. 3+1=4 4+4=8 8+8=16
Hopefully this helped, and please add me as brainliest.
Final answer:
The simplified forms of the expressions (2 + 9 + 4) and (3 + 1 + 4 + 8) are 15 and 16, respectively. The placement of parentheses affects the outcome of mathematical operations significantly, and careful evaluation following the order of operations is essential for accurate simplification, particularly when nested expressions are involved.
Explanation:
The question requires matching each mathematical expression with its simplified form. Let's simplify the given expressions:
(2 + 9 + 4) simplifies to 2 + 9 + 4 = 15.
(3 + 1 + 4 + 8) simplifies to 3 + 1 + 4 + 8 = 16.
Now, to address your example concerning the importance of the placement of parentheses, consider the expression 2 + (3 x 5). If the parentheses are around (2 + 3), the result is different than if the parentheses are around (3 x 5). Without any parentheses, the order of operations dictates that multiplication is done before addition. Hence:
(2 + 3) x 5 = 5 x 5 = 25 (since addition within parentheses is done first, followed by multiplication).
2 + (3 x 5) = 2 + 15 = 17 (since multiplication within parentheses is done first, followed by addition).
If you double president Reagans age at the time of his first inauguration and subtract his age at the time he died,the result is 45 years. How old was president Reagan when he died?
Answer:
93
Step-by-step explanation:
Let's say President Reagan was x years old when he died. He was 69 years old at his first inauguration
(2*69)-x = 45
Wait. But how will we find x in that equation?
--> (2*69)-45 = x
That's better.
2*69 = 138
138-45 = 93
x=93
A teacher allows her students to decide whether to use the mean, median, or mode to determine their test averages. One student determined that he will receive the highest average if he uses the mean. Which test scores are his?

Final answer:
Option D, with scores of 100, 87, 94, 94, and 81, yields the highest average when calculated using the mean, making it the best choice for the student seeking the highest test average.
Explanation:
The question asks which set of test scores will give the highest average if calculated using the mean. To find the answer, we calculate the mean of each set of scores:
A: (95+82+76+95+96)/5 = 88.8
B: (79+80+91+83+80)/5 = 82.6
C: (65+84+75+74+65)/5 = 72.6
D: (100+87+94+94+81)/5 = 91.2
Among the options, option D has the highest mean.
Therefore, the student with test scores of 100, 87, 94, 94, and 81 will have the highest average when using the mean to calculate.
How many different combinations of 3 books can Erika take on a trip if she has 5 books
Answer:
10 combinations
Step-by-step explanation:
What we have to do is calculate the number of combinations of 3 in 5.
The formula for the combinations is:
nCr = n!/r!(n-r)!
in this case n = 5 and r = 3
replacing
5C3 = 5!/3!(5-3)! = 5!/(3!*2!)
5C3 = 10
So there are 10 combinations in which Erika can enjoy the books on her trip
Answer:
The number of different combinations of 3 books that Erika can take on a trip if she has 5 books is 10
Step-by-step explanation:
Here we have the formula for combination given as follows;
[tex]\binom{n}{r} = \frac{n!}{r!(n-r)!}[/tex]
Where n is the number of set elements = 5 and
r = Number of subset elements = 3
Therefore, plugging the values, we have;
[tex]\binom{5}{3} = \frac{5!}{3!(5-3)!} = \frac{120}{6(2)} = 10[/tex]
Therefore, the number of different combinations of 3 books that Erika can take on a trip if she has 5 books = 10.

.If a golf ball has a diameter of 4.3 centimeters and a tennis ball has a diameter of 6.9 centimeters. Find the difference between the volumes of the two balls.
Answer:
130.43 cm³
Step-by-step explanation:
To find the difference between the volumes of the balls, we must first find the volumes of the balls. To find the volume of each ball, we must first determine their shape. We understand that both balls are spherical.
The volume V of a sphere wit radius r is given as
V = 4/3 πr³
where r is the result when the diameter of the sphere is divided by 2.
Hence the radius of the Golf ball
= 4.3cm/2
= 2.15cm
radius of the tennis ball
= 6.9cm/2
= 3.45cm
The difference between the volumes of the two balls
= 4/3 π (3.45³ - 2.15³)
= 130.43 cm³

If the campers at Camp Grilled Meat prefer hot dogs to hamburgers by a ratio of 4:3, and they need 500 hot dogs, how many hamburgers will they need?
Answer:
375
Step-by-step explanation:500 equals 100% divide by 4 its 125 times 3 equals 375, your welcome
Answer:
They will need 375 hamburgers.
Step-by-step explanation:
Keeping the ratio in mind, we solve this problem by cross multiplying. Set up the ratio 4/3 and set it equal to the greater ratio of 500/(an unknown number of hamburgers, represented by x). Cross multiply to end up with the equation 4x=1500. (Cross multiplying is multiplying each numerator by the opposite denominator). Solve for x in the above equation using SADMEG. You divide 1500 by 4 and end up with 375 hamburgers.
Speedy Boat Rental charges a $15 deposit fee plus $2 for each hour
of use to rent a paddle boat. Write an equation to find out how many
hours, h, they rented the Boat if the total cost was $33,
Answer:
y=2x+15
Step-by-step explanation:
h=9
The equation to find the number of hours the boat was rented is $33 = $15 + ($2 imes h). After subtracting the deposit fee and dividing by the cost per hour, the solution is h = 9, indicating the boat was rented for 9 hours.
The equation to find out how many hours, h, the boat was rented for when the total cost was $33 can be represented as follows:
Total cost = Deposit fee + (Cost per hour imes Number of hours)
Substituting the given values, we have:
$33 = $15 + ($2 imes h)
To solve for h, we subtract $15 from both sides of the equation:
$33 - $15 = $15 - $15 + ($2 imes h)
So, $18 = $2 imes h
Next, we divide both sides of the equation by $2 to solve for h:
$18 \/ $2 = ($2 imes h) \/ $2
h = 9
This means they rented the boat for 9 hours.
A data set includes 103 body temperatures of healthy adult humans having a mean of 98.9degreesf and a standard deviation of 0.67degreesf. construct a 99% confidence interval estimate of the mean body temperature of all healthy humans. what does the sample suggest about the use of 98.6 degreesf as the mean body temperature?
A 99% confidence interval for the mean body temperature can be calculated using the sample mean, standard deviation, and the t-score corresponding to the confidence level. The findings may suggest that the commonly accepted average body temperature of 98.6°F could be reconsidered if it does not fall within this interval.
Constructing a 99% Confidence Interval
To construct a 99% confidence interval for the mean body temperature of all healthy humans, we use the sample mean, standard deviation, and the t-distribution since the population standard deviation is not known. With a mean of 98.9°F, a standard deviation of 0.67°F, and a sample size of 103, we can calculate the margin of error using a t-score that corresponds to the 99% confidence level.
First, we find the t-score from the t-distribution table for 102 degrees of freedom (n-1) that corresponds to a 99% confidence level. Then, we calculate the margin of error using the formula:
Margin of Error (E) = t-score * (standard deviation / sqrt(n))
This margin of error is then added and subtracted from the sample mean to obtain the confidence interval:
Lower Limit = Mean - Margin of Error
Upper Limit = Mean + Margin of Error
This confidence interval provides a range within which we can be 99% confident that the true mean body temperature of all healthy humans lies.
Implications for 98.6°F as Average Body Temperature
The sample suggests that the mean body temperature of 98.6°F might not be accurate for all individuals. If the constructed 99% confidence interval does not contain the traditional mean of 98.6°F, it could indicate that the average body temperature is different than what has been historically taught.
The 99% confidence interval estimate of the mean body temperature of all healthy humans is approximately (98.7294, 99.0706) degrees Fahrenheit.
To construct a 99% confidence interval for the mean body temperature of all healthy humans, we'll use the formula:
[tex]\[ \text{Confidence Interval} = \bar{x} \pm z \left( \frac{s}{\sqrt{n}} \right) \][/tex]
Let's calculate the confidence interval:
[tex]\[ \text{Confidence Interval} = 98.9 \pm 2.576 \left( \frac{0.67}{\sqrt{103}} \right) \]First, let's calculate \(\frac{s}{\sqrt{n}}\):\[ \frac{s}{\sqrt{n}} = \frac{0.67}{\sqrt{103}} \approx 0.0662 \][/tex]
Now, we can find the margin of error:
[tex]\[ \text{Margin of Error} = 2.576 \times 0.0662 \approx 0.1706 \]Finally, construct the confidence interval:\[ \text{Confidence Interval} = 98.9 \pm 0.1706 \][/tex]
So, the 99% confidence interval estimate of the mean body temperature of all healthy humans is approximately (98.7294, 99.0706) degrees Fahrenheit.
Can 4 cm, 7 cm, 9 cm be a right triangle
Answer:
No
Step-by-step explanation:
For it to be a triangle c² = a² + b²
The longest side is c (9)
and 81 ≠ 49 + 16

Answer:
No
Step-by-step explanation:
Since it might be a right triangle, we can test the values using the Pythagorean theorem.
[tex]a^2+b^2=c^2[/tex]
a and b are the legs, and c is the hypotenuse.
We know that 4 and 7 are the legs, or a and b. This is because they are two smaller sides. We know that 9 is the hypotenuse, or c. This is because it is the longest side.
[tex]4^2+7^2=8^2[/tex]

Final answer:
Circumference is the distance around a circle, calculated as C = πd or C = 2πr, depending on whether the diameter or radius is known. (Option A,C,D)
Explanation:
Circumference is the term used to describe the distance around a circle. When calculating the circumference, you can use different formulas depending on the information you have about the circle. If you know the diameter (d), the circumference (C) can be found by multiplying the diameter by pi (π), using the formula C = πd. Alternatively, if you know the radius (r) of the circle, you can use the formula C = 2πr since the diameter is twice the radius (d = 2r).
The correct answers to the question are:
A) distance around the circleC) To find the circumference C of a circle if you know the diameter d is to multiply pi by the diameterD) To find the circumference if you know the radius, replace d with 2r in the formulaIt's important to note that the space inside the circle is referred to as the area, not the circumference, and the formula for circumference is not C = pi + r as stated in option E, but rather C = πd or C = 2πr.

What single decimal multiplier would you use to increase by 7% followed by a 9% increase?
Answer:
The decimal multiplier is 1.1663
Step-by-step explanation:
Since the increases are done successively we can find decimal numbers for each one and multiply both to have a single decimal representing the whole operation. When there's a increase this means that we have the original value (100%) summed by some other value, in this case 7%, so the new value would be 100% + 7% = 107%, we can transform this to a decimal number by dividing it by 100, so 107/100 = 1.07. The same applies to the 9% increase, so we would have 109/100 = 1.09. We can now multiply both to obtain a single decimal multiplier, we have:
1.07*1.09 = 1.1663

What is a square pyramid?"It is a three-dimensional geometric shape that has a square base and four triangular sides that are joined at a vertex."
What is net?"It is a two-dimensional structure which forms a three-dimensional geometric structure by folding."
According to the problem,
The base of the square pyramid has a square and if a three dimensional structure of a net formed into a pyramid is looked at, we can see 1 face of the square at the base.
A pyramid is comprised of 4 triangles joined together at the vertex.
Again, if a three dimensional structure of a pyramid is looked at, we can see 4 faces of the pyramid.
Now in order to align into a single unit to be joined at the vertex, the triangles have to be identical. They will have similar faces with the same base and slant height.
Therefore, 1 square face and 4 triangular faces adds up to five total faces.
Hence, we can conclude that the net will have one square face, four triangular faces and a total of five faces with the triangular faces being similar.

2 large boxes and 5 small boxes has a total weight of 102 kilograms
mathematically it can be represented as
2X + 5Y = 102
--------------------------------------------------------------------------
we have two equation
8X + 3 Y = 187 -------------------A
2X + 5Y = 102 -------------------B
multiplying equation B with 4 on both side of equation we have
4*(2X + 5Y) = 4*102
=> 8X + 20Y = 408 -------------------C
Now subtracting equation A and C on both sides we have
8X + 3 Y - (8X + 20Y ) = 187 -408
8X - 8X + 3 Y - 20Y = -221
-17Y = -221
=> Y = -221/-17 = 13
Now substituting value of Y in equation B we have
2X + 5*13 = 102
=> 2X + 65 = 102
=> X = (102-65)/2 = 18.5

Weight of large box = 18.5 Kg
Weight of small box = 13 Kg
The large box weighs 17 kg and the small box weighs 13 kg.
Explanation:Let's denote the weight of a large box as x and the weight of a small box as y. We can set up a system of equations to solve for the weights:
8x + 3y = 187 (equation 1)
2x + 5y = 102 (equation 2)
To solve the system, we can multiply equation 1 by 2 and equation 2 by 8 to eliminate x:
16x + 6y = 374 (equation 3)
16x + 40y = 816 (equation 4)
Subtracting equation 3 from equation 4, we get:
34y = 442
Solving for y, we find y = 13.
Substituting this value back into one of the original equations, we find x = 17.
Therefore, the large box weighs 17 kilograms, and the small box weighs 13 kilograms.

1 4/9 + 2 6/9 is equal to 4 1/9, true or false?
Answer: True
Explanation: To add mixed numbers, first add the fractions.
So here, we have 4/9 + 6/9 which is 10/9.
Then add the whole numbers.
So we have 1 + 2 which is 3.
So our answer is 3 and 10/9.
But notice, that since 10/9 is an improper fraction,
our answer is not in lowest terms.
10/9 can be rewritten as the mixed number 1 and 1/9.
So 3 and 10/9 is the same as 3 + 1 and 1/9 which is 4 and 1/9.
Since 4 and 1/9 is in lowest terms, this is our final answer.
So we can say that 1 and 4/9 + 2 and 6/9 is 4 and 1/9.
Sharon has 72 beads. She has twice as many sphere beads as cylinder beads. How many of each kind of bead does Sharon have? How did you solve the problem? How can you check your check.
Answer:
Sphere=48 beads
Cylinder=24 beads
Step-by-step explanation:
Let the number of cylinder beads be y and since she has twice as many sphere beads, the sphere beads will be 2y
The sum of sphere and cylinder beads will be y+2y=3y
This sum is equivalent to the total number given as 72
Therefore, equating 3y to be equal to 72 we obtain the equation
3y=72
Dividing by 3 on both sides we obtain that
Y=72/3=24 beads for cylinder
Since the sphere is 2y then 2*24=48
To confirm, it is evident that 48+24=72
Also, the number 48 is double/twice the number 24
