A rectangular photograph measuring 2 inches by 4 inches is enlarged by a scale factor of 8. What are the new dimensions of the photograph? Can ya explain how you got the answer too?
Answer:
original: 2x4
scale factor: 8
new dimensions:
2x8=16
4x8=32
(To get the new dimensions all you have to do is multiply the sides by the scale factor)
Step-by-step explanation:
The new dimensions of the photograph is [tex]64 \ in^{2}[/tex]
What is a scale factor?The scale factor is a measure for similar figures, who look the same but have different scales or measures. Suppose, two circle looks similar but they could have varying radii. The scale factor states the scale by which a figure is bigger or smaller than the original figure.
According to the question
[tex]S_{1} =2\times4=8[/tex]
[tex]S_{2} =8S_{1} =8\times8=64[/tex]
The new dimensions of the photograph is [tex]64 \ in^{2}[/tex]

Given,
Diameter = 16 feet
So, radius = 16 feet/2 = 8 feet
Circumference = 2πr
So, circumference of this circle
= 2πr
= 2 × 3.14 × 8 feet
= 3.14 × 16 feet
= 50.24 feet
b.
Given,
Diameter = 16 feet
So, radius = 16 feet/2 = 8 feet
Area = πr²
So, area of this circle

= 200.96 feet²
Answer:
Done

A law in Washington, D.C., restricts a new building's height to no more than 20 feet taller than the width of the street it faces. You design a building with stories that are each 15 feet tall for a street that is 88 2/3 feet wide. What is the greatest number of stories your building can have?
_______ Stories
How much shorter is your building than the height restriction?
________Feet
It can be up to 20 feet taller so add 20
To the width:
88 2/3 + 20 = 108 2/3
Divide total height by the height of one story:
108 2/3 / 15 = 7.24
The building can have 7 stories.
b. 7 x 15 = 105 total feet
108 2/3 -105 = 3 2/3 feet below the restrictions
There are two types of tickets sold at the Canadian Formula One Grand Prix race. The price of 5 grandstand tickets and 3 general admission tickets is 2490. The price of 6 grandstand tickets and 6 general admission tickets is 3540 . What is the price of each type of ticket?
Answer: Grandstand: 360, General Admission: 230
Step-by-step explanation:
Use any variable you like but:
Let g represent grandstand ticketsLet a represent general admission ticketsYou know:
5 Grandstand tickets and 3 general admission tickets is 2490:
5g + 3a = 2490The price of 6 grandstand (g) tickets and 6 general admission tickets (a) is 3540
6g + 6a = 3540You want to find out: What is the price of each ticket. To do this either use substitution or elimination.
I will demonstrate elimination:
To do elimination, you want to cancel out one variable. This means you want to multiply each side of the equation by a number. I see 3a and 6a. This means multiply by -2. Again, you want to eliminate the variable.
5g +3a = 2490 → -10g - 6a = -4980Now, add the two equations together: Notice how you can line them up vertically to see how they can add together.
-10g - 6a = -4980+6g + 6a = 3540After that step you get: -4g = -1440Now you can solve for the g (grandstand tickets):
-4g = -1440g = 360You now know grand stand tickets cost 360. Take one of your original equations and solve for a (general admission tickets). To double check your work, they should satisfy both equations.
5g + 3a = 24905(360) + 3a = 24903a = 690a = 2306g +6a = 35406(360) +6a = 35406a = 1380a = 230Therefore general admission tickets cost 230, and grandstand tickets cost 360!

What is the y-intercept, end behavior and zeros of this polynomial function?

Describe the direction of the parabola and determine the zeros and y-intercept.
f(x) = (x – 3)(x – 2).
WILL MARK BRAINLIEST IF BOTH ANSWERS ARE CORRECT
Answer:
To determine its end behavior, look at the leading term of the polynomial function. Because the power of the leading term is the highest, that term will grow significantly faster than the other terms as x gets very large or very small, so its behavior will dominate the graph.

Perry saved 4 twenty-dollar bills, 2 ten-dollar bills, 3 dimes, and 2 pennies. Before winter break, he bought a new racing video game for $49.86. How much money did Perry have left?
Answer:
[see answer below]
Step-by-step explanation:
"Perry saved 4 twenty-dollar bills, 2 ten-dollar bills, 3 dimes, and 2 pennies."
4 * 20 = 80
2 * 10 = 20
3 * 0.1 = 0.3
2 * 0.01 = 0.02
80 + 20 + 0.3 + 0.02 = $100.32
100.32 - 49.86 = 50.46

Graph the line that represents a proportional relationship between ddd and ttt with the property that an increase of 3 units in ttt corresponds to an increase of 8 units in ddd.
What is the unit rate of change of ddd with respect to ttt? (That is, a change of 1 unit in t will correspond to a change of how many units in d?)
The unit rate of change of d with respect to t is 8/3
How to graph the line?The statement is given as:
increase of 3 units in t corresponds to an increase of 8 units in d.
This can be represented using the following ratio
t : d = 3 : 8
Express as fraction
t/d = 3/8
See attachment for the graph of t/d = 3/8
The unit rateIn (a), we have:
t/d = 3/8
Inverse both sides
d/t = 8/3
This means that:
Slope or Rate = 8/3
Hence, the unit rate of change of d with respect to t is 8/3

Math problem for high school
Answer:
50/3
Step-by-step explanation:
area of triangle = 10
area of circle = 10
area of triangle + area of circle = 20
The white sector of the circle has central angle 60°.
Its area is 1/6 the area of the circle.
To find the gray area, you must subtract the white area from the area of the circle and also subtract the white area from the area of the triangle. Two times the white area is 1/3 the area of the circle.
gray area = 20 - (1/3)10
gray area = 20 - 10/3
gray area = 60/3 - 10/3
gray area = 50/3
Answer:
The white sector of the circle = (1/6) (10) = 10/6 = 5/3
So....the grey area = 10 + 10 - 2 (5/3) = 20 - 10/3 = 60/3 - 10/3 = 50 / 3
