Answer:16 = 3x

Step-by-step explanation:

Perimeter = Sides surrounding a figure

The triangle has 3 sides, each named "x".

Thus, because the perimeter is equivalent to 16 inches, 3x = 16.

A car has 15 gallons of gas in its tank. The car travels 35 miles per gallon of gas. It uses 135 of a gallon of gas to go 1 mile

STALIN [3.7K]

Answer:

525 miles

Step-by-step explanation:

Two unit rates are given in this problem:

miles per gallon
gallons per mile

Since we want to find miles, the appropriate rate to use is miles per gallon:

distance = mile/gallon x gallons

distance =35 miles/gallon x 15 gallons = 525 milles

The car can travel 525 miles on 15 gallons of gas.

The principal represents an amount of money deposited in a savings account subject to

Nataliya [291]

Compound interest is the adding of interest to the principle sum of a loan or deposit. The amount of money in the account after 2 years is $7426.30, while the interest earned in 2 years is $426.30.

<h3>What is compound interest?</h3>

Interest on interest, or compound interest, is the adding of interest to the principle sum of a loan or deposit. It's the outcome of reinvesting interest rather than paying it out, so that interest is received on the principal plus previously collected interest in the next quarter.,

$A = P(1+ \dfrac{r}{n})^{nt}$

where A is the final amount

P is the principal amount

r is the rate of interest

n is the number of times interest is charged in a year

t is the number of years

Given the principal amount is $7,000 while the rate of interest is 3% which is compounded annually.

A. The amount of money in the account after 2 years will be,

A = $7000(1 + 0.03)² = $7426.30

B. The amount of interest earned is will be,

The amount of interest earned = $7426.30 - $7000 = $426.30

Hence, the amount of money in the account after 2 years is $7426.30, while the interest earned in 2 years is $426.30.

What is the equation of the line connecting (1,5) and (4,14)?

german

To find the slope of the line:
(y2-y1)/(x2-x1)
(14-5)/(4-1)=(9)/(3)=3

Only one of your 4 possible answers has 3 as a slope. However, plugging in each point into the y=mx+b equation, the y-intercept consistently comes out as 2..
y=mx+b
14=3(4)+b b=2
5=3(1)+b b=2
y=3x+2
If there is a consistent, positive slope (from your question, this does not seem to have a quadratic as an option), 3x+5 is not even a viable solution because x=1 when the y-value is 5 (and thus no other x value {0} could have a y-value of 5). It seems as though you have a typo on your hands. Hopefully this helps?
