A race
sashaice [31]

Answer: 187.7 mph

Step-by-step explanation:

v = 125 mph

t = 1.2 min

v2 = ?

t2 = 0.8 min

We can use the rule of 3 here. It's the inverse rule of 3 because as time decreases, speed increases.

\frac{125mph}{x} =\frac{1.2min}{0.8min}

x = \frac{(125)(1.2)}{0.8}

x=187.5mph

What is the length of the unknown side?
777dan777 [17]

Answer:

Hi there!

The correct answer is: 20

Step-by-step explanation:

knowing this a right triangle you can solve this problem in two ways

Method One: Pythagorean Theorem

a^2 + b^2 = c^2 then plug in the values

(12)^2 + (16)^2 = c^2 this will come out to be 400 = c^2

square root both sides and you get c = 20

Method Two: Pythagorean Identities

if you ever learned the Pythagorean identity 3,4,5

this triangle is indeed a 3,4,5 triangle it's just that each side is multiplied by the factor 4

so in this case since you know the missing side should be 5 you just multiply 5 by 4 and you get 20

Bond [772]

Answer: $7,488

Step-by-step explanation:

For answer B:

The formula for the new balance would be A=P(1 + r)t

A = new balance

P = principal balance -> $900

r = rate (in decimal form)

t = time in years -> 8 years

To find the rate, convert 4% to decimal  

4/100 = 0.04

A=P(1+ r)t  

A=900(1+0.04)8

A=900(1.04)8

A=$7,488
