Answer:
113 miles
Step-by-step explanation:
Distance = 180 km
Number of km per mile = (8/5) = 1.6 miles
Number of miles between the schools:
Distance / Number of kilometers per mile
180km / 1.6
= 112.5 miles
= 113 miles
Distance between the schools is approximately 113 miles

Explain the meaning of F(30) = 8,950 in this situation
Answer:
when you have something like f(x)=... that means
f means function
and every time you see an x or the variable in the parenthesis you plug in for that so it's f(x) =3x+1 then f(2)= 3x+1 every time you see x you plug in 2
Given the function below, find f(-5): f(x)= x^2 + 3x - 21
Answer:
Step-by-step explanation:
f(-5) = (-5)^2 + 3(-5) - 21
= 25 - 15 - 21
= -11
Answer:
11
Step-by-step explanation:
) f(x) = 3x2 + 5 and y = 3x2 + 5 ... You read this problem like this: “given f of x equals 4x plus one, find f of 2. ... Given f(x)= 3x – 4, f(5) = 11.
Cullen said that multiplying a fraction by a fraction equivalent to 1 always results in a fraction that has the same value as the original fraction. Is he correct?
Simplify.
56bc
64cd
I need ASAP
Answer:
8c(7b + 8d)
Step-by-step explanation:
Supposing that you are ADDING these terms, you have 56bc + 64cd. This can be factored as follows: 56bc + 64cd = 8c(7b + 8d)

Determine a series of transformations that would map Figure N onto Figure O
Answer:
Reflect over x-axis. Then translate up 5 units.
Help I need to turn this in today:)
Total surface area
=2 ×(area of triangle) +( area of rectangle 1) + (area of rectangle 2) + (area of rectangle 3)
2×(1/2 × 16 ×12) + (10×12)+(16×10)+(20×10)
=672 cm²
Figure A is translated 3 units right and 2 units up. The translated figure is labeled figure B. Figure B is reflected over the x-
axis. The reflected figure is labeled figure C. Which best explains why figure A is congruent to figure C?
Answer:
A. A = B and B = C
Answer:
A) A=B and B=C

2. Rohan spends x daily and saves y per day. What is his income after 3 weeks?
Step-by-step explanation:
Amount of money spend in 1 day = x
So, amount of money spend in 7 days = (7x)
⇒ Amount of money spend in 1 week = (7x)
Amount of money saved in 1 week = y
∴ Income in 1 week = (7x + y)
So, income in 3 weeks = [3 x (7x + y)]
= (21x + 3y)
Answer:
total income after 3 weeks=7×3(x+y=21x+21y
income=saving + expenses

Suppose someone gives you 6 to 1 odds that you cannot roll two even numbers with the roll of two fair dice. This means you win 6 dollars if you succeed and lose 1 dollar if you fail. What is the expected value of this game to you. What can you expect if you play 200 times
Answer:
0.75 ;
150
Step-by-step explanation:
Probability of rolling two even numbers :
{1, 2, 3, 4, 5, 6}
P(even) = 3 / 6 = 1/2
From a roll of 2 dice :
P(even) * P(even) = 1/2 * 1/2 = 1/4 = 0.25
P(not even) = 1 - 1/4 = 3/4
X : ____ 6 _______ - 1
P(x) ____ 0.25 ____ 0.75
Expected value :
Σx*p(x) = (6*0.25) + (-1 * 0.75)
= 1.50 - 0.75
= 0.75
If 200 games are played :, n = 200
Expected value * n
0.75 * 200
= 150

Please I’m in the middle of a test help
Answer:
[tex]x = \frac{8}{3}, y = \frac{4}{3}[/tex]
Step-by-step explanation:
Solve for y in the first equation.
[tex]y=\frac{4}{3}[/tex], replace y with [tex]\frac{4}{3}[/tex]
Solve for in the first equation.
[tex]x = \frac{8}{3}, y = \frac{4}{3}[/tex]
good luck, hope this helps :)
Answer:
x= 2.375
y=4/3
Step-by-step explanation:
2x-y=4
1--3=3y
4=3y
y=4/3
2x-3/4=4
2x = 4.75
x= 2.375
A rectangular prism has a volume of 3,510 feet cubed. It has a height of 12
feet and a length of 13 feet. What is it's width? *
Answer:
22.5 feet.
Step-by-step explanation:
Volume = length * height + width, so:
3510 = 13 * 12 * width
So width = 3510 / (13*12)
= 22.5 feet.

I need help I don’t get how to solve it plsss help me
Answer:
Step-by-step explanation:
They give you the equation, you must substitute the x values into the equation to find the y values.
Example on top equation:
y=-5x so the y values would be
y=-5(-1)=5
y=-5(0)=0
y=-5(1)=-5
y=-5(2)=-10

A 3-gallon bottle of fabric softener costs $33.24. What is the price per quart?
Answer:
$2.77 per quart.
Step-by-step explanation:
There are four quarts in a gallon.
4 * 3 = 12
There are 12 quarts in 3 gallons.
[tex]\frac{price}{quart} =\frac{33.24}{12}=\frac{33.14/12}{12/12}=\frac{2.77}{1}=\boxed{2.77}[/tex]
The price per quart should be $2.77.
Hope this helps.
