Answer:
$5.40
Step-by-step explanation:
To find the increase we need to consider our variables.
Current Rate = $4.50
Increase Percentage = 20% or 0.20
Now we can find the new rate by multiplying the Current Rate to the Increase Percentage and add it to the Current Rate again.
Total Price w/ Increase = ($4.50 x 0.20) + $4.50
Total Price w/ Increase = $0.90 + $4.50
Total Price w/ Increase = $5.40

Answer:
y = -5
Step-by-step explanation:
To solve this, we simply plug in 4 into x and then solve for y. We have:
[tex]-3x+9y=-57\\[/tex]
Now we put 4 into x and do some algebra and solve for the value of y:
[tex]-3x+9y=-57\\-3(4)+9y=-57\\-12+9y=-57\\9y=-57+12\\9y=-45\\y=\frac{-45}{9}\\y=-5[/tex]

The figure is made up of 2 hemisphere and a cylinder what is the exact volume?
Answer: D. 648*π in^3
Step-by-step explanation:
The formula for the volume of a cylinder is
[tex]V=\pi *r^2*h[/tex]
V=1130.973355 in^3
or simply
V=1130.97 in^3
or
V=360*π in^3
Since, you know the radius of the hemisphere on top, you also know the radius since the height of the hemisphere is the same as it is wide.
Next, the formula for the volume of a sphere is
[tex]V=\frac{4}{3} \pi *r^3[/tex]
since you have two hemispheres, its the same thing as solving for one sphere because two halves make a whole. So, the volume of the sphere is
V= 904.7786842 in^3
or simply
V= 904.78 in^3
or
V=288 *π in^3
Finally, you add both of the volumes together to get
V= 2035.75204 in^3
or simply
V= 2035.75 in^3
or
V= 648*π in^3

Otis had a salad for $4.50, a sandwich for $6.25, and a drink at his favorite restaurant. The tax for the entire meal was $0.54. What was the price of the drink?
Answer:
Price of the drink = $1.25
Step-by-step explanation:
4.5% * ( $4.5 + $6.25 + drink) = $0.54
4.5/100 * ( $4.5 + $6.25 + drink) = $0.54
0.045 * ( $4.5 + $6.25 + drink) = $0.54
0.045/0.045 * ( $4.5 + $6.25 + drink) = $0.54/0.045
( $4.5 + $6.25 + drink) = $12
10.75 + drink = $12
drink = $12 - $10.75
drink = $1.25
The price of the drink is $1.25
How to determine the price of the drink?The given parameters are:
Tax amount = $0.54
Salad = $4.50
Sandwich = $6.25
Let the price of the drink be x.
Given that the sales tax is 4.5%, we have:
4.5% * ( $4.5 + $6.25 + x) = $0.54
Divide both sides by 4.5%
( $4.5 + $6.25 + x) = $12
Evaluate the sum
$10.75 + x= $12
Subtract $10.75 from both sides
x = $1.25
Hence, the price of the drink is $1.25

A construction worker is building a wall. The wall is
20
yd
long. He needs to place a stud every
16
in
. The first stud has already been placed at one end of the wall. How many additional studs are needed, if the last stud will be placed at the other end of the wall? First fill in the blanks on the left side using the ratios shown.
I believe it is 45 studs to the end of the wall
Answer:
Step-by-step explanation:
First, convert 20 yds to 60 ft. and then from 60 ft to 720 in.
Use the formula for the nth term of an arithmetic sequence:
l = a + (n-1)d:
Here l = 720 ft, and a = 0. The common difference, d, is 16 in. Our task is to determine how many studs are needed.
Substituting the knowns, we get 720 = 0 + (n - 1)(16), which simplifies to:
720 = (n-1)(16).
Divide both sides by 16 to isolate (n-1): 45 = n - 1.
Adding 1 to both sides results in 46 = n.
46 studs total are needed; if the worker has already placed the first stud, then 45 additional studs are needed.
A flashlight is projecting onto a wall, as shown below
Answer:
n = 30
Step-by-step explanation:
The triangles share the same angle measures, so they are similar triangles. The side lengths of similar triangles are proportional to each other, so we can set up a proportion and solve for n...
16 is to 20 as 24 is to n
16/20 = 24/n now solve for n by cross multiplying
16n = 480
n = 30 (divide both sides by 16)
We are given that the original triangle and its projection are similar. This means that the corresponding angles of the two triangles are congruent, and the ratios of their side lengths are equal.
We are also given the lengths of two sides of the original triangle: 16 cm for the base and 20 cm for the hypotenuse. We are asked to find the missing length on the projection, which corresponds to the base of the original triangle.
To solve this problem, we can set up a proportion based on the similar triangles. Let x be the missing length on the projection:
(base of original triangle) / (base of projection) = (hypotenuse of original triangle) / (hypotenuse of projection)
Substituting the known values:
16 cm / x = 20 cm / 24 cmCross-multiplying:
16 cm * 24 cm = x * 20 cm384 [tex]cm^2[/tex] = 20x [tex]cm^2[/tex]x = 384 [tex]cm^2[/tex] / 20 [tex]cm^2[/tex]x = 19.2 cmTherefore, the missing length on the projection is 19.2 cm. However, the answer choices are all rounded to one decimal place.
Rounding 19.2 cm to one decimal place gives us 19.0 cm. Therefore, none of the provided options are correct.

Chicken = 64
Pasta = 5 * 8 (cause 25 * 8 = 200)
Pasta = 40
Answer- C] There are 32 more students who want beef meal more than want a chicken meal
The best prediction of the meals wanted by the 200 students can be determined based on the proportions from the random survey. Option A, which states that there are 16 students who want a beef meal, is the best prediction.
Explanation:The best prediction of the meals wanted by the 200 students can be determined by considering the proportions from the random survey.
The number of students who want a beef meal can be estimated by finding the proportion of students who want a beef meal in the survey and multiplying it by the total number of students. In this case, the proportion is 12/25 and the estimated number of students who want a beef meal is (12/25) * 200 = 96 students.The number of students who want either a chicken meal or a pasta meal can be estimated by adding the number of students who want a chicken meal and the number of students who want a pasta meal in the survey. In this case, the estimated number of students who want either a chicken meal or a pasta meal is 8 + 5 = 13 students.The difference in the number of students who want a beef meal and the number of students who want a chicken meal can be estimated by subtracting the number of students who want a chicken meal from the number of students who want a beef meal in the survey. In this case, the estimated difference is 12 - 8 = 4 students.The difference in the number of students who want a pasta meal and the number of students who want a chicken meal can be estimated by subtracting the number of students who want a chicken meal from the number of students who want a pasta meal in the survey. In this case, the estimated difference is 5 - 8 = -3 students.Based on the survey results, the best prediction of the meals wanted by the 200 students is
96 students who want a beef meal

Determine the area of each of the following polygons using the area formula you created in part d.
Polygon Area
regular pentagon with apothem of approximately 9 inches and side length of 13 inches
regular octagon with apothem of approximately 5 centimeters and side length of 4 centimeters
regular hexagon with apothem of approximately 6 feet and side length of 7 feet
Answer:
1. The area of regular pentagon = 292.5 inches²
2. The area of the regular octagon = 80 cm²
3. The area of the regular hexagon = 126 feet²
Step-by-step explanation:
∵ The area of any regular polygon = 1/2 × perimeter × apothem
1. Regular pentagon
∵ Regular pentagon has 5 equal sides
∵ The perimeter of the regular pentagon = 5 × side length
∵ S = 13 inches
∴ P = 13 × 5 = 65 inches
∵ apothem = 9 inches
∴ A = 1/2 × 65 × 9 = 292.5 inches²
2. Regular octagon
∵ Regular octagon has 8 equal sides
∵ The perimeter of the regular octagon = 8 × side length
∵ S = 4 cm
∴ P = 4 × 8 = 32 cm
∵ apothem = 5 cm
∴ A = 1/2 × 32 × 5 = 80 cm²
3. Regular hexagon
∵ Regular hexagon has 6 equal sides
∵ The perimeter of the regular hexagon = 6 × side length
∵ S = 7 feet
∴ P = 7 × 6 = 42 feet
∵ apothem = 6 feet
∴ A = 1/2 × 42 × 6 = 126 feet²

Which equation models the line that passes through points (4, 6) and (−4, 8)
Answer:
y = - [tex]\frac{1}{4}[/tex] x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
To calculate m use the slope formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (4, 6) and (x₂, y₂ ) = (- 4, 8)
m = [tex]\frac{8-6}{-4-4}[/tex] = [tex]\frac{2}{-8}[/tex] = - [tex]\frac{1}{4}[/tex], hence
y = - [tex]\frac{1}{4}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 4, 8 ), then
8 = 1 + c ⇒ c = 8 - 1 = 7
y = - [tex]\frac{1}{4}[/tex] x + 7 ← equation of line
