Answer:
about 12 1/2 minutes
each mile he went to school took him 5 minutes and if his friend's house is 2 1/2 miles away then 2.5x5= 12.5
======================================================
Work Shown:
20 min = 20/60 = 1/3 of an hour
distance = rate*time
d = r*t
4 mi = (x mph)*(1/3 hr)
4 = x*(1/3)
4*3 = x
x = 12 mph
Damon's speed is 12 mph
--------------
Now calculate the time it takes go travel to his friends house.
d = r*t
2.5 = 12*t
t = (2.5)/12
t = 25/120
t = (5*5)/(5*24)
t = 5/24
He takes 5/24 of an hour to go from school to Stefan's house.
Multiply by 60 to convert to minutes
(5/24)*60 = 12.5 minutes

Answer:
m = 21
Step-by-step explanation:
-5 = 2 - [tex]\frac{m}{3}[/tex]
Multiply both sides of the equation by 3.
-15 = 6 - m
Swap sides so that all variable terms are on the left hand side.
6 - m = -15
Subtract 6 from both sides.
-m = -15 - 6
Subtract 6 from −15 to get −21.
-m = -21
Multiply both sides by −1.
m = 21

Nathaniel is deciding between two parking garages. Garage A charges an initial fee of $8 to park plus $6 per hour. Garage B charges an initial fee of $11 to park plus $5 per hour. Let AA represent the amount Garage A would charge if Nathaniel parks for tt hours, and let BB represent the amount Garage B would charge if Nathaniel parks for tt hours. Write an equation for each situation, in terms of t,t, and determine the hours parked, t,t, that would make the cost of each garage the same.
Answer:
tt = 3 would make the cost of each garage the same.
Step-by-step explanation:
Garage A: $8 + $6(h)
AA = $8 + $6(tt)
Garage B: $11 + $5(h)
BB = $11 + $5(tt)
If AA = BB
then,
$8 + $6(tt) = $11 + $5(tt)
($6-$5)(tt) = $11 - $8
$1(tt) = $3
tt = 3

A deck of Uno cards has 4 colors (suits): Red, Yellow, Green, Blue
Each color has cards numbered 1 to 9,
so the total number of these cards = 49 = 36
(An Uno deck also has other, special cards, but for this question, those special cards are removed for the
deck. Only the numbered cards are used.)
a) Event E = Randomly selecting an UNO card that is Red.
What is the probability of event E?
(Enter a fraction; it does not have to be reduced.)
b) Event F = Randomly selecting an Uno card that is some number from 1 to 6 of any of the 4 colors.
What is the probability of event F?
(Enter a fraction; it does not have to be reduced.)
c) How many cards are in the intersection of events E and F?
d) P(E and F) = the probability of choosing a card in the intersection of events E and F: P(E and F) = ?
e) Let event G = E or F.Use the General Addition Rule to compute P(G): P(G) = P(E) + P(F) - P(E and F)
f) How many cards are in event G?

The cube root of 175616 is:
Answer:
56
Step-by-step explanation:
We can represent 175616 as the product of primes as below:
175616=2×2×2×2×2×2×2×2×2×7×7×7
Grouping the factors to form the triplet, we have:
175616=2×2×2 ×2×2×2 ×2×2×2 ×7×7×7
Taking the cube root, we have:
[tex]\sqrt[3]{175616} = 2*2*2*7[/tex]
Simplifying, we have:
[tex]\sqrt[3]{175616} = 56[/tex]
Hence, the cube root of 175616 is 56

The length of a side of a square in inches is approximately 5.29 inches.
What is Square?A square is a four sided polygon where each side are equal and each angle equal to 90 degrees.
The formula to find the area of a square is,
Area of a square = a²,
where "a" is the side length of the square.
Given, area of the square = 28 square inches.
Let "a" be the side length of the square.
a² = 28
a = √28 inches ≈ 5.29 inches.
Hence the length of a side is 5.29 inches.

what is the slope of the line whose equation is 13x+y-5=0?
Answer:
-13
Step-by-step explanation:
1. To find the slope, it'd be much to convert the line from standard form to slope-intercept form, meaning we have to solve for y. (y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.)
2. (Solving)
Step 1: Subtract 13x from both sides.
[tex]13x + y - 5 - 13x = 0 - 13x[/tex] [tex]y - 5 = -13x[/tex]Step 2: Add 5 to both sides.
[tex]y - 5 + 5 = -13x + 5[/tex] [tex]y = -13x + 5[/tex]3. As you can see, -13 is in the place of m, the slope.
Therefore, the slope of the equation 13x + y - 5 = 0 is -13.

As AD = 1/4AB and DE ║ AC, the ratio CE/CB = 1/4, or CE = 1/4CB
Find the coordinates of D:
x = 1 + 1/4(17 - 1) = 1 + 4 = 5y = 5 + 1/4(1 - 5) = 5 - 1 = 4Find the coordinates of E:
x = 13 + 1/4(17 - 13) = 13 + 1 = 14y = 9 + 1/4(1 - 9) = 9 - 2 = 7Find the coordinates of the midpoint M of DE:
x = (5 + 14)/2 = 19/2 = 9.5y = (4 + 7)/2 = 11/2 = 5.5Divide 2y2 + 8 by 2y + 4. Which expression represents the quotient and remainder?
y – 2 –
y + 2 –
y + 2 +
y – 2 +
When 2(y^2) + 8 is divided by 2y + 4 is equal to (y - 2) + (16 / (2y + 4)). The expression represents the quotient is the 2y + 4. While the expression represent the remainder is 16 / (2y + 4). The remainder of the given expression can also be solve using the remainder theorem.
Answer:
We need to perform division of 2y2 + 8 by 2y + 4. To solve this problem, we need to use the long method of division such as shown below:
y - 2 r. 16
-----------------------
2y+4 √2y2 + 0y + 8
- (2y2 + 4y)
-----------------------
0y2 - 4y + 8
- (-4y -8)
-----------------------
0y + 16
The answer is y-2 + (16/(2y+4)) on which the remainder is 16 / (2y+4).
