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

Find the arc length of the semicircle.
Either enter an exact answer in terms of π (pi) or use 3.14 and enter your answer as a decimal.
Answer:
6 pi
Step-by-step explanation:
The arc length is 1/2 of the circumference
C = pi * d
So the arc length is 1/2 C
arc length= 1/2 ( pi *d)
= 1/2 pi(12)
= 6 pi
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
Hope this helps you.
Answer:
$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

First one : y=1/3x+4.32
Second one: y=3x-2
Explanation: try Desmos. its a magical machine
Answer:
see explanation
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 )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (5, 6) and (x₂, y₂ ) = (- 1, 4)
m = [tex]\frac{4-6}{-1-5}[/tex] = [tex]\frac{-2}{-6}[/tex] = [tex]\frac{1}{3}[/tex] , then
y = [tex]\frac{1}{3}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 1, 4 ) , then
4 = - [tex]\frac{1}{3}[/tex] + c ⇒ c = [tex]\frac{12}{3}[/tex] + [tex]\frac{1}{3}[/tex] = [tex]\frac{13}{3}[/tex]
y = [tex]\frac{1}{3}[/tex] x + [tex]\frac{13}{3}[/tex] ← equation of line
-----------------------------------------------------------------------
The equation of a line in point- slope form is
y - b = m(x - a)
m is the slope and (a, b) a point on the line
Here m = 3 and (a, b) = (- 2, 0 ) , then
y - 0 = 3(x - (- 2) ) , that is
y = 3(x + 2)
y = 3x + 6 ← equation of line

What is the y-intercept, end behavior and zeros of this polynomial function?
g(x) = (x + 2)(x − 1)(x − 2).
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.

Answer:
Blank1: (-1/10)
Blank2: 1
Blank3: 5
Step-by-step explanation:
First we can see that numerator is equal to 1 in the last equation, so the second missing value is 1. Looking at the middle equation we can differ that the denominator is 10. This means the missing number in the third equation is equal to ten, so a*2=10, where the answer "a" is the missing value. Solve the equation by dividing both sides by 2 leaving a=5. Final step is to make 1/5+b=1/10, where ''b" is the answer for the first blank. Solve the equation by subtracting (1/5) from (1/10) leaving b=(-1/10)
An airplane travels 1800 miles in 3 hours flying with the wind. On the return trip, flying

Andrew and Michael are 15 miles apart. If they walk towards each other, they meet in 3
hours. If they both walk in the same direction, Michael overtakes, Andrew in 8 hours.
How fast does each boy walk?
Answer:
75 miles miles an hour. (First one)
5 mph for the second one.
Step by Step:
1800%2F3 = u + v (1) is the equation for the flight with the wind.
(Here "u" is the airspeed of the airplane with NO wind,
"v" is the wind speed)
1800%2F4 = u - v (2) is the equation for the flight against the wind.
Simplify equations (1) and (2) and write them as a system:
u + v = 600, (1')
u - v = 450. (2')
Now add the two equations (1') and (2'). You will get
2u = 1050 ---> u = 1050%2F2 = 525 miles per hour.
Having this, you can easily determine "v" from (1'):
v = 600 - 525 = 75 miles per hour.

Second one will be 15 divided by 3 = 5mph

The number of possible outcomes is 2*2*2 = 8
The number of ways of getting 3 tails is 1
The odds against - the ratio of the number of ways that an outcome cannot occur compared to in how many ways it can occur.
ways it can occur -1

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!

Answer:
The 3rd semi-circle equals 31.
Step-by-step explanation:
Since the Pythagorean Theorem states that "The sum of the areas of the two squares on the legs (a and b) equals the area of the square on the hypotenuse (c)," we can find the answer of the 3rd semi-circle by finding the sum of each of the 2 smaller semi-circles and adding them together.
