Your answer is 80. A triangle’s angles add up to 180 degrees. Therefore, you need to subtract 30 and 70 from 180 to find your answer: 180-(30+70)=80 or 180-70-30=80

Peter works as a delivery person for a bike shipping company. The graph shows a linear model for his delivery times on different

aev [14]

Answer/Step-by-step explanation:

✍️The equation of the line in point-slope form:

The equation is given as $y - b = m(x - a)$ , where,

(a, b) = a point on the line.

$slope (m) = \frac{y_2 - y_1}{x_2 - x_1}$

Let's find the slope (m) of the line, housing (3, 21) and (6, 12):

$slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 21}{6 - 3} = \frac{-9}{3} = -3$

Substitute a = 3 and b = 21, m = -3 into $y - b = m(x - a)$ .

Thus, the point-slope equation would be:

✅ $y - 21 = -3(x - 3)$

✍️The equation of the line in slope-intercept form:

Rewrite $y - 21 = -3(x - 3)$ , so that y is made the subject of the formula.

$y - 21 = -3x + 9$

Add 21 to both sides

$y = -3x + 9 + 21$

$y = -3x + 30$

✅The slope-intercept equation of the line is $y = -3x + 30$

Where,

-3 = how much did his delivery time decrease per day (slope)

30 = how long it initially took Peter to deliver his packages (y-intercept)

An amount of $21,000 is borrowed for 10 years at 3.25% interest, compounded annually. If the loan is paid in full at the end of

Yanka [14]

The formula for total loan cost is attached.
10 years = 120 payments
MONTHLY Interest = .0325 / 12 = 0.0027083333 

total = 0.0027083333 * 21,000 * 120 / (1-(1.0027083333)-120 
total = 6,825 / (1- 0.7228448406 )
total = 6,825 / 0.2771551594 
total = 24,625.20

How many 1/3 cm by 1/3 cm by 1/3 cm cubes will fit in a 1 cm by 1 cm by 1 cm box? Explain how you know.

Tems11 [23]

1/3^3=0.037 recurring. 1^3= 1. 1/0.37=27.027. That rounds to 27 so you can fit 27 cubes into the box.

Zev has 36 pencils and 45 erasers. He wants to use all of the pencils and erasers to make identical packages for his friends. Wh

soldier1979 [14.2K]

Answer:

Step-by-step

If you don't want to have anything left over, then the highest common factor is

36: 2 * 2 * 3 * 3

45: 3 * 3 * 5

The highest common factor is 9.

So he can make nine packages with

4 pencils in each one and

5 erasers in each package.
