The rectangular bed of a truck is 1 9⁄10 meters long, 1 1⁄2 meters wide, and 1⁄2 meter tall. What is the volume of the truck's bed?
Answer:
1 17/40 m^3
Step-by-step explanation:
Volume = l*w*h
= 1 9/10 * 1 1/2 * 1/2
Changing the mixed numbers to improper fractions
1 9/10 = (10*1+9) /10 = 19/10
1 1/2 = (2*1+1)/2 = 3/2
1/2 = 1/2
V = 19/10* 3/2*1/2
=57/40
Changing this back to a mixed number
40/40 + 17/40
1 17/40
Answer:
1 17/40 m³
Step-by-step explanation:
1.9 × 1.5 × 0.5
= 1.425 m³
19/10 × 3/2 × 1/2
= 57/40
= 1 17/40 m³

(a) Find the surface area of the cube shaped box. Show your work. (2 points for correct answer, 1 point for work
These boxes are then packed into a shipping container with dimensions of
(b) Draw a net of the rectangular prism. Label the net with the measurements. (1 point for net, 1 point for labeling measurements)
(c) How many boxes of office supplies can be packed into the larger container for shipping? Show your work. (2 points for correct answer, 1 point for work)
Answer:
1.
a) 357 inches³ of water more would be required to fill the tank
b) Riley is not correct, the volume of the larger aquarium is 27
times larger than the volume of the smaller on
c) Riley is not correct, the surface area of the larger aquarium is 9
times the surface area of the smaller one
2.
a) There are 8 boxes of office supplies can be packed into
the larger box for shipping
b) The surface area of the shipping box is 567 inches²
Step-by-step explanation:
1.
a) * Lets study the first aquarium:
- The formula for volume is V = l × w × h
∴ It is a rectangular box of dimensions 16 in , 8.5 in , 10.5 in
∴ Its volume = 16 × 8.5 × 10.5 = 1428 inches³
* The full capacity of this aquarium is 1428 inches³
- Riley noticed that it 3/4 full of water, then still can fill with
1/4 to be full
- Why 1/4 because 1 - 3/4 = 1/4
∴ The volume of 1/4 the aquarium = 1/4 × 1428 = 357 inches³
* There are 357 inches³ of water more would be required to fill the tank
b) * Lets talk about the larger aquarium
- Each dimension will be triple to construct the larger aquarium
- That means we will multiply each dimension of the small aquarium by 3
- That means the ratio between each dimension in the larger
aquarium to the smaller aquarium is 3 : 1
∴ The ratio between their volumes will be (3 : 1)³
- Because we will multiply each dimension by 3 and they
are 3 dimensions, that means 3 × 3 × 3 ⇒ 3³
∴ The ratio between their volumes = 27 : 1
∴ Riley is not correct because the volume of the larger aquarium is 27
times larger than the volume of the smaller aquarium
c) * Similar for the surface area of the larger aquarium
- Each dimension will be triple to construct the larger aquarium
- That means we will multiply each dimension of the small aquarium by 3
- That means the ratio between each dimension in the larger
aquarium to the smaller aquarium is 3 : 1
∴ The ratio between their surface area will be (3 : 1)²
- Because we will multiply each dimension by 3 and to get the
surface area we multiply each two dimensions for the six faces
and then add them
∴ The ratio between their surface area = 9 : 1
∴ Riley is not correct because the surface area of the larger aquarium
is 9 times larger than the surface area of the smaller aquarium
2.
a) * Lets think about this situation
- We want to fill some office supplies boxes of side length
4.5 inches inside the shipping box of dimensions 18 in , 9 in , 4.5 in
- That means the volume of the shipping box is how many times
the volume of the office supplies box
∴ The number of office supplies boxes = the volume of shipping box ÷ the volume of the office supplies box
∵ the volume of shipping box = 18 × 9 × 4.5 = 729 inches³
∵ the volume of the office supplies box = 4.5 × 4.5 × 4.5 = 91.125 inches³
∴ The number of office supplies boxes = 729 ÷ 91.125 = 8 boxes
* There are 8 boxes of office supplies can be packed into
the larger box for shipping
b) Look to the Net of the shipping box
- The net has 6 faces shaped rectangles
- Each two faces are congruent
- To find the surface area we will add all the areas of the 6 faces
- Two faces with dimensions 18 in and 9 in
∴ Their areas = 2 (18 × 9) = 324 inches²
- Two faces with dimensions 18 in and 4.5 in
∴ Their areas = 2 (18 × 4.5) = 162 inches²
- Two faces with dimensions 4.5 in and 9 in
∴ Their areas = 2 (4.5 × 9) = 81 inches²
∴ The total surface area = 324 + 162 + 81 = 567 inches²
* The surface area of the shipping box is 567 inches²
Final answer:
The question involves calculating the surface area of a cube, drawing a net of a rectangular prism, and determining how many smaller cubes fit within the larger prism. However, required measurements are missing, making it impossible to provide exact answers to the calculations.
Explanation:
The student is tasked with answering questions related to geometry, specifically involving cubes and rectangular prisms. To find the surface area of the cube-shaped box, one would need the side length of the cube. The formula for the surface area of a cube is SA = 6s², where s is the side length. However, since the side length is not given in the question, this cannot be completed as presented.
To draw a net of a rectangular prism, you would draw six rectangles that correspond to the faces of the prism. Each rectangle would be labeled with its corresponding dimensions. Again, the specific dimensions of the container are not provided in the question.
Finally, to determine how many boxes can be packed into the larger container, you would need the volume of both the boxes and the container. The volume of each is calculated by multiplying the length, width, and height for rectangular prisms, or raising the side length to the third power for cubes. Then, divide the volume of the container by the volume of one box to find the number of boxes that can fit inside, assuming no wasted space. Without the actual dimensions, this calculation cannot be completed.
For whаt vаluе оf x does 3^4х = 27^x-3?
Answer:
x = -9
Step-by-step explanation:
3^4х = 27^(x-3)
Replace 27 with 3^3
3^4х = 3^3^(x-3)
We know that a^b^c = a^ (b*c)
3^4х = 3^(3(x-3))
Since the bases are the same, the exponents are the same
4x = 3(x-3)
Distribute
4x =3x-9
Subtract 3x from each side
4x-3x = 3x-3x-9
x = -9

(PLEASE HELP!) The central angle of a sector is 72 degrees and the sector has an area of 15.71. Find the radius.
Answer: The radius is 5 units (approximately)
Step-by-step explanation: The area of a sector with central angle X is given as;
Area = (X/360) x pi x r^2
Since the area has been given as 15.71 units, we can input the known values into the formula as follows;
15.71 = (72/360) x 3.14 x r^2
By cross multiplication we now have
(15.71/3.14) = 1/5 x r^2
(15.71/3.14) x 5 = r^2
78.55/3.14 = r^2
25.0159 = r^2
Add the square root sign to both sides of the equation
5.001 = r
The radius is equal to 5 units (approximately)

suppose y varies inversely with x. Write an equation if y=-3 when x=17
Answer:
y = -51 ÷ x
Step-by-step explanation:
The standard format of a inversely proportional equation goes by the format of y = k ÷ x. The question asks us to write an equation if y = -3 when x = 17 and y varies inversely with x.
So we substitute the values y = -3 and x = 17 in the equation y = k ÷ x
K = constant, we have to work this out
-3 = k ÷ 17
-3 × 17 = k
k = -3 × 17
k = -51
k = -51 So then we put this back into the original y = k ÷ x to find our final equation which is y = -51 ÷ x

A cat had a litter of 5 kittens. If each sex is equally likely, what is the probability that 3 or less were female kittens? 0.3125 0.500 0.8125 0.2500
Answer:
WHAT IS THIS QUESTION AHHH BUT 03125
Step-by-step explanation:
Answer:
Probability of 3 or less = 0.8125.
Step-by-step explanation:
This is a binomial probability distribution.
Prob(0 females) = 5C0(1/2)^5 = 0.03125
Prob(1 female) = 5C1 (1/2)^5 = 0.15625
Prob(2 females) = 5C2(1/2)^5 = 0.3125
Prob(3 females) = 5C3(1/2)^5 = 0.3125
Adding these we get 0.8125.

Find the exact volume of the cylinder. Diameter 10 ft and height 8 ft
The exact volume of the cylinder with a 10 ft diameter and 8 ft height is found using the formula V = πr²h. With a diameter of 10 ft, the radius is 5 ft. The calculated volume is 628.318 cubic feet.
Explanation:To find the exact volume of a cylinder with a diameter of 10 ft and a height of 8 ft, we can use the following formula:
V = πr²h
Where V is the volume, r is the radius of the cylinder (half of the diameter), h is the height, and π (pi) is approximately 3.14159. Since the diameter is given as 10 ft, the radius will be 5 ft (half of the diameter).
Substituting our values into the formula gives us:
V = π × (5 ft)² × 8 ft
V = 3.14159 × 25 ft² × 8 ft
V = 3.14159 × 200 ft³
V = 628.318 ft³
Therefore, the exact volume of the cylinder is 628.318 cubic feet.
Franklin rolls a pair of six-sided fair dice with sides numbered 1 through 6.
The probability that the sum of the numbers rolled is either even or a multiple of 5 is
Answer:
The answer is 7/36.
Step-by-step explanation:
First, you find out how many possible outcomes there are from rolling a pair of dice. On one cube, you can roll a 1,2,3,4,5, or 6; so there are 6 outcomes. Since there are two cubes, you multiply 6 by itself to get a total of 36 possible outcomes. Next, you find the probability of the sum of the numbers rolled being an even number; the possibilities are 2,4,6,8,10, or 12, which is 6/36. The probability of rolling a multiple of 5; the one possibility is just 5, since we already accounted for rolling a 10 as an even number. So that is 1/36. The word or says that we add the two probabilities, so the final answer is 6/36+1/36=7/36.
Answer: For plato

A shoe store donated a percent of every sale to hospitals.The total sales were $7,150 so the store donated $286.What percent of $7,150 was donate to the hospitals
Final answer:
To find the percent of sales donated to hospitals, divide the amount donated ($286) by the total sales ($7,150) and multiply by 100, resulting in 4%.
Explanation:
The question asks to calculate what percent of the total sales was donated to the hospitals by the shoe store. To find this, we use the basic formula for calculating percent: part over total, times one hundred, equals percent. In this case, the part is the amount donated ($286) and the total is the total sales ($7,150).
So, the calculation would be: (286 / 7,150) x 100 = 4%. Thus, the shoe store donated 4% of its total sales to hospitals.
A bullet has an initial velocity of 1000 meters per second. 5 seconds later, it has a velocity
of 500 meters per second. What is the acceleration of the bullet?
O
A. 300 meters/second/second in the opposite
direction of travel
O
B. 100 meters/second second in the same
direction of travel
O
C. 100 meters/second second in the same
direction of travel
O
D. 300 meters/second/second in the opposite
direction of travel
Answer:
b or c
Step-by-step explanation:
being that the answers are the same it should be 100 meters/second in the same direction. you will take the initial velocity, 1000, and subtract the new velocity, 500, and divide it by time. the direction deals with acceleration and if it is flying strait with no forces acting on it to move it, it will remain strait.
solve 49x^2+64=0 by using square roots
Answer:
x = ±i8/7
Step-by-step explanation:
49x^2 +64 = 0
Subtract 64 from each side
49x^2 +64-64 = 0-64
49x^2 = -64
Divide by 49
49x^2/49 =-64 /49
x^2 = - 64/ 49
Take the square root of each side
sqrt(x^2) = ±sqrt(- 64/ 49)
x = ±sqrt(- 64/ 49)
We know sqrt( ab/c) = sqrt(a) sqrt(b)/sqrt(c)
x = ±sqrt(- 1) sqrt(64)/( 49)
We know that the sqrt(-1) = i
x = ±i8/7

The largest possible circle is cut out of a square whose side length is 8 feet. What will be the approximate area, in square feet, of the remaining board?
5 FT 2 squared
10 Ft 2 squared
15 Ft 2 squared
20 Ft 2 Squared
Answer:
20ft ^2 (squared)
Step-by-step explanation:
We deduct the circle area from the square area but first find out the radius triangle segment the 1/diagonal of the square. To find the hypotenuse h= c=r
h^2 =c = a+ b
h^2 = 8^2+ 8^2
h^2 =√64 + √64
h^2 =√128 = 11.313708499/3 = 3.77123616633
r= 5.65ft or 5.66ft rounded up
Square area formula = L x W = 8ft x 8ft = 64ft^2
Circle area formula= A=πr2 = (π = 3.14159265359 (3.77123616633x 3.77123616633) = 14.2222222222 x 3.14159265359 = 44.680428851
A = 14.2 x π
A = 44.68ft
64 - 44.68 = 19.32ft^2
The answer must be 20ft ^2 squared.

True or False? The first distribution shown below has a smaller mean than
does the second distribution.
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12
101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112
O
A. True
O
B. False
The first distribution with numbers ranging from 1 to 12 has a mean of 6.5, while the second distribution with numbers from 101 to 112 has a mean of 105.5. It is therefore True that the first distribution has a smaller mean than the second distribution.
The question asks whether the first distribution (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12) has a smaller mean than the second distribution (101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112). To determine this, we will calculate the mean of both distributions.
The mean of a distribution is calculated by adding all the numbers in the set and then dividing by the count of numbers.
For the first distribution:
Mean = (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12) / 12
Mean = 78 / 12
Mean = 6.5
For the second distribution:
Mean = (101 + 102 + 103 + 104 + 105 + 106 + 107 + 108 + 109 + 110 + 111 + 112) / 12
Mean = 1266 / 12
Mean = 105.5
Comparing the means of both distributions, the first distribution has a mean of 6.5 and the second distribution has a mean of 105.5. Therefore, it is True that the first distribution has a smaller mean than the second distribution.
Furthermore, this corresponds to elementary properties of means where adding the same value to all elements of a distribution shifts the mean but does not affect the comparison of means of two distributions if the same value is added to each distribution.
