Sara and her family went to eat at Pappasito's for dinner. The total cost of the meal is $76.50. Sara left a 10% tip.
Determine their total cost, including the tip.
Answer:
The answer to your question is $84.15
Step-by-step explanation:
Data
cost of the meal = $76.50
tip 10%
total cost = ?
Process
1.- Calculate the 10% of $76.50 using proportions and cross multiplication.
$76.50 --------------- 100%
x ----------------- 10%
x = (10 x 76.5) / 100
x = 765/100
x = 7.65
2.- Calculate the total cost
Total cost = cost of the meal + tip
-Substitution
Total cost = $76.50 + $7.65
-Result
Total cost = $84.15

How do you find the arc length in a circle given any angle?
You find the circumference and multiply it by the central angle. If the central angle is in degrees, you divide that by 360. If the central angle is in radians, you divide by 2pi.
How do i solve -1=-3r +2r
To solve this, you need to isolate/get the variable "r" by itself in the equation:
-1 = -3r + 2r Combine like terms(terms that have the same variable and power/exponent.) The only like terms you can combine are -3r and 2r
-1 = -r Divide -1 on both sides to get "r" by itself
[tex]\frac{-1}{-1} =\frac{-r}{-1}[/tex] (two negative signs cancel each other out and become positive)
1 = r or r = 1
Answer:R=-1
Step-by-step explanation: You would have to first do the math for the equation, then you would have to work in the "R" and given the answer is smaller than the equation itself we can tell that the "R" is a negative. So, if we add the -3 and the 2 we get 1,so we can say that the "R" are both equal to -1 then we put it in the equation. We get -1=1 we add the "R's" then get -1

4. *Each pair of polygons is similar. Find the value of x.
Step-by-step explanation:
since both objects and sides are similar, you can set each side equal, then you cross multiply, and do subtraction, then find x.
Final answer:
To find the value of x in similar polygons, justify the similarity, write an equation relating the sides, algebraically solve for x, calculate, and then check that the result is reasonable.
Explanation:
The subject of this question is Mathematics, and it is likely at the high school level, as it involves finding a missing length in similar polygons, which requires knowledge of ratios and properties of similar figures, often covered in high school geometry courses.
Steps to find the value of x:
Justify that the triangles are similar: This can typically be done by verifying that the triangles meet the criteria of similarity, such as having identical angles or corresponding sides in proportion.
Write an equation that relates the sides of the triangles: Utilize the properties of similar triangles to write ratios that compare the lengths of corresponding sides.
Algebraically isolate the unknown quantity x.
Plug in numbers and calculate the answer.
Check the answer to ensure it seems reasonable.
It's also important to remember that if two triangles are similar, their corresponding lengths are proportional, which you can express algebraically with a statement such as AB/CD = EF/GH where AB, CD, EF, and GH are corresponding sides of the similar triangles.

Answer:
Step-by-step explanation:
Let x represent the number of hours for which you can rent the truck.
truck rental company charges a weekend rate of $50.75 plus $8.25 for each hour a truck is rented. It means that the cost of renting the truck for x hours would be expressed as
50.75 + 8.25x
You have at most $125.00 to spend on a truck rental. Therefore, the inequality that describes the number of hours you can rent the truck is
50.75 + 8.25x ≤ 125

Leila, Charlie, and Joe have a total of $144 in their wallets. Joe has 4 times what Leila has. Charlie has $6 more than Leila. How much does each have?
Answer:
The amounts of money each has are:
Joe = $92
Charlie = $29
Leila = $23
Step-by-step explanation:
To solve this, we will convert the statements into an equation, and use that to solve for the unknowns, as follows:
total amount = $144
Let Leila's share be S
Joe's share = 4 times Leila's = 4S
Charlie's share = $6 + Leila's share = 6 + S
Joe's share + Charlie's Share + Leila's Share = $144
4S + (6 + S) + S = 144
4S + 6 + S + S = 144
4S + 2S + 6 = 144
6S + 6 = 144
6S = 144 - 6 = 138
S = 138 ÷ 6 = $23
Therefore Leila's share 'S' = $23
Joe share= 4S = 4 × 23 = $92
Charlie's share = 6 + 23 = $29

The lateral area of the rectangular prism is calculated to be 208m² using the formula for lateral area of a prism. Assuming the width is the same as the length, the surface area is calculated to be 240m² using the formula for surface area of rectangular prism.
Explanation:In mathematics, the lateral area and surface area of a rectangular prism can calculated using specific formulas. To calculate the lateral area of a rectangular prism, which is the area excluding the base and the top, you use the formula: Lateral area = Perimeter of the base x Height. Given the base length is 4m, and the height is 13m, the perimeter of the base is 4 x 4m = 16m. So, the lateral area = 16m x 13m = 208m².
The surface area of a rectangular prism is calculated using the formula: Surface area = 2lw + 2lh + 2wh. where l is the length, w is the width, and h is the height. In this case, the width is not given. Assuming it's the same as the length (since it's also 4m in the given figure), the surface area = 2*(4m*4m) + 2*(4m*13m) + 2*(4m*13m) = 32m² + 104m² + 104m² = 240m².

A regulation baseball can weigh no more than 149 grams. A factory produces baseballs with weights that are normally distributed with a mean of 146 grams and a standard deviation of 2.3 grams.
Answer:
0.9032
Step-by-step explanation:
Given that:
mean (μ) = 146 grams and standard deviation (σ) = 2.3 grams
The z score is a measurement used in statistics to calculate how far a value is from the mean in a normal distribution. The z score is given as:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
For the baseball not to weigh more than 149 grams i.e x = 149 g
[tex]z=\frac{x-\mu}{\sigma}=\frac{149-146}{2.3} =1.30[/tex]
From the probability distribution table, P(x < 149) = P(z < 1.30) = 0.9032 = 90.32%
A Pontiac Grand am I Pinterest so will Roger turn pike traveling at 50 mph. Once half an hour later a ford Mustangs enter the turnpike at the same location and travel in the same distance at 80 mph. How long would it take for the mustang to catch up to the grand am ?When it catch up how far will the two cars have traveled on the turnpike
Answer:
It will take 0.8333h for the mustang to catch up to the grand am.
The two cars will have traveled 66.664 miles on the turnpike
Step-by-step explanation:
The position for each car can be modeled by equations in the following format:
[tex]S(t) = S(0) + vt[/tex]
In which S(t) is the position t hours after the last car(the Ford Mustang) has left, S(0) is the position of each car when the Ford Mustang left and v is the speed of each car, in miles per hour.
Pontiac
Traveling at 50 mph, which means that [tex]v = 50[/tex].
The Ford Mustang leaves half an hour after the Pontiac. The Pontiac travels at 50 mph, which means that in this interval, the Pontiac will have traveled 0.5*50 = 25 mph. This means that S(0) = 25. So
[tex]S_{P}(t) = 25 + 50t[/tex]
Ford Mustang
Leaves from position 0, so S(0) = 0.
Travel in the same distance at 80 mph, so [tex]v = 80[/tex]. So
[tex]S_{M}(t) = 80t[/tex]
How long would it take for the mustang to catch up to the grand am ?
This is t when
[tex]S_{M}(t) = S_{P}(t)[/tex]
[tex]80t = 25 + 50t[/tex]
[tex]30t = 25[/tex]
[tex]t = \frac{25}{30}[/tex]
[tex]t = 0.8333[/tex]
It will take 0.8333h for the mustang to catch up to the grand am.
When it catch up how far will the two cars have traveled on the turnpike
This is either [tex]S_{M}(0.8333)[/tex] or [tex]S_{P}(0.8333)[/tex], since they will be in the same position. So
[tex]S_{M}(t) = 80t[/tex]
[tex]S_{M}(0.8333) = 80*0.8333 = 66.664[/tex]
The two cars will have traveled 66.664 miles on the turnpike
The Ford Mustang will catch up to the Pontiac Grand Am in 18.75 minutes and they will have traveled a total of 25 miles on the turnpike.
Explanation:To find out how long it takes for the Ford Mustang to catch up to the Pontiac Grand Am, we need to determine the time it takes for the Mustang to cover the same distance that the Grand Am has already traveled. The Grand Am has a head start of half an hour at a speed of 50 mph, so it has covered a distance of:
Distance = Speed x Time = 50 mph x 0.5 hr = 25 miles
Now, we can calculate the time it takes for the Mustang to cover this distance:
Time = Distance / Speed = 25 miles / 80 mph = 0.3125 hr = 18.75 minutes
Therefore, it will take the Mustang 18.75 minutes to catch up to the Grand Am.
When the two cars catch up, they will have traveled a total distance of 25 miles, which is the distance covered by the Grand Am in the half-hour head start.

Answer:
Answer letter D
Step-by-step explanation:
-3x + 3y = 9
2x - 7y = -14
Let's start by simplifying both equations:
-3x + 3y = 9 (divide everything by 3)
2x - 7y = -14 (divide everything by 2)
We will then have:
-x + y = 3
x - [tex]\frac{7}{2}[/tex]y = - 7
Then we sum both equations, eliminating x and isolating y to find its value!
y + (- [tex]\frac{7}{2}[/tex]y) = 3 + (- 7)
[tex]\frac{2}{2}[/tex]y + (- [tex]\frac{7}{2}[/tex]y) = - 4
Summing the fractions of y we have
- [tex]\frac{5}{2}[/tex] y = - 4 .: y = [tex]\frac{8}{5\\}[/tex] .: y = 1 [tex]\frac{3}{5}[/tex](we found y!)
Now we substitute y in one of the previous equations to find x:
-3x + 3 × ( [tex]\frac{8}{5\\}[/tex] ) = 9
-3x + [tex]\frac{24}{5\\}[/tex] = 9
-3x = 9 - [tex]\frac{24}{5}[/tex]
-3x = [tex]\frac{45}{5}[/tex] - [tex]\frac{24}{5}[/tex]
-3x = [tex]\frac{21}{5}[/tex]
x = [tex]\frac{21}{5}[/tex] ÷ -3 (this is tricky, but it's the same as [tex]\frac{21}{5}[/tex] × -[tex]\frac{1}{3}[/tex] )
x = - [tex]\frac{7}{5}[/tex] .: x = - 1 [tex]\frac{2}{5}[/tex](finally found x!)
Bringing everything together we have:
x = - 1 [tex]\frac{2}{5}[/tex]
y = 1 [tex]\frac{3}{5}[/tex]

Scott runs 4 sprints of 20 yards each. If he continues his routine, how many practices will it take for Scott to have sprinted a total of 2 miles combined?
Answer:
It will take 44 practices for Scott to have sprinted a total of 2 miles combined
Step-by-step explanation:
This question can be solved using rules of three.
First step:
Scott practice is measured in yards.
We want to know how many practices it will take for him to have sprinted 2 miles.
So we pass 2 miles to yards
Each mile has 1760 yards.
So 2 miles is 1760*2 = 3520 yards.
A practice:
4 sprints of 20 yards each.
So 4*20 = 80 yards.
A practice is 80 yards. How many practices for 3520 yards?
1 practice - 80 yards
x practices - 3520 yards
80x = 3520
x = 3520/80
x = 44
It will take 44 practices for Scott to have sprinted a total of 2 miles combined

Clare made $160 babysitting last summer. She puts the money in the saving account that pays 3% interest per year. If Clare doesn't touch the money in her account, she can find the amount she'll have the next year by multiplying her current amount by 1.03. How much money will Clare have in her account after 1 year?
Answer:
Clare account balance after one year will be $164.80
Step-by-step explanation:
Interest = PRT/100
Principal P = $160, Rate r = 3%, and time t = 1 year
Interest = (160*3*1)/100
Interest =480/100
= $4.80
The total balance in Clare's account after 1 year will be $160 + $4.80
= $164.80

Answer: 8.3
Step-by-step explanation: 37 divided by=12.3 then 12.3 - 4
Answer: the taxi travelled 11 miles
Step-by-step explanation:
Let x represent the number of miles that the taxi traveled.
The cost of the taxi was 4 dollars plus 3 dollars for each mile traveled. It means that the total cost of renting and driving the taxi over x miles is
4 + 3x
The Lopez rented the taxi and when they arrived at their destination, the total cost 37 dollars. It means that
4 + 3x = 37
3x = 37 - 4
3x = 33
x = 33/3
x = 11 miles

Find an equation for the line that passes through the points (-3,-2) and (1,4)
Answer:
y=2/3x
Step-by-step explanation:
First, we have to find the slope, which is [tex]\frac{(y_{1} -y_{2})}{(x_{1}-x_{2}}[/tex]
(-3-1)/(-2-4)
-4/-6
2/3 is slope.
y=2/3x+-___
substitute in -3 from first point
y=-2+__=-2
y=2/3x+0
y=2/3x
Answer:
y + 2 = (3/2) (x+3) (point slope form)
Step-by-step explanation:
(see attached for reference)
Given
(x₁, y₁) = (-3,-2)
(x₂, y₂) = (1,4)
Since we are given 2 points, it would be easiest to express the equation of the line in point-slope form (see attached)
(y - y₁) = m (x - x₁)
we already have the values for x₁ and y₁, hence we only need to find the slope m (see 2nd attached graphic)
m = (y₂-y₁) / (x₂ - x₁)
= [4 - (-2) ] / [1 - (-3)]
= (4+2) / (1+3)
= 6/4
= 3/2
substituting the value for m and the values for x₁ and y₁:
(y - y₁) = m (x - x₁)
[y - (-2)] = (3/2) [x - (-3)]
y + 2 = (3/2) (x+3)

A professor has 24 pairs of socks in his drawer. 18 pairs are black and the rest are brown. He always wears black pants. He does not pay much attention to which socks he puts on each day. Supposed he selects one pair of socks on Monday and one on Tuesday. Since he has lots of clean socks in the drawer he does not do laundry. What is the likelihood that the professor's socks matched his pants on both days (i.e. he picked black socks)
Answer:
The likelihood that the professor's socks matched his pants on both days is 0.5625
Step-by-step explanation:
Total no. of pair of socks = 24
No. of black pairs = 18
We are given that he selects one pair of socks on Monday and one on Tuesday. Since he has lots of clean socks in the drawer he does not do laundry.
So, It is a case of replacement
He always wears black pants.
We are supposed to find he likelihood that the professor's socks matched his pants on both days i.e. Black socks both days.
So ,Probability of wearing black socks on Monday = [tex]\frac{18}{24}[/tex]
So ,Probability of wearing black socks on Tuesday =[tex]\frac{18}{24}[/tex]
So,the likelihood that the professor's socks matched his pants on both days = [tex]\frac{18}{24} \times \frac{18}{24}=0.5625[/tex]
Hence the likelihood that the professor's socks matched his pants on both days is 0.5625
Final answer:
The probability that the professor picks black socks on both Monday and Tuesday is 9/16.
Explanation:
The question asks about the probability that a professor will pick black socks on two consecutive days without doing laundry in between. With 24 pairs of socks, of which 18 pairs are black and 6 pairs are brown, we will calculate the likelihood of the professor picking black socks on both Monday and Tuesday.
First, the probability of picking black socks on Monday (first pick) is 18 black pairs divided by 24 total pairs, which simplifies to:
Probability of black socks on the first pick = 18/24 = 3/4Since the socks are not washed between Monday and Tuesday, the number of socks available remains the same. Therefore, the probability of picking black socks again on Tuesday (second pick) is also 3/4.
To find the overall probability that the professor picks black socks on both days, we must multiply the probability of the first event by the probability of the second event. In this case:
Overall probability = Probability on Monday × Probability on TuesdayOverall probability = 3/4 × 3/4 = 9/16The probability that the professor's socks matched his pants (picked black socks) on both days is 9/16.
