Find the slope of the line through each pair of points (20,18),(-9,-14)

Answers

Answer 1

Answer: the slope = ( -14 - 18 ) / ( -9 -20 ) = (-32)/(-29) = 32/29.

Answer 2

Answer: (Y2-y1)/(x2-x1)
(-14-18)/(-9-20)
-32/-29
=32/29

the slope is 32/29

What is the perimeter of a rhombus-shaped street sign with a 35-cm side? A. 280 cm
B. 140 cm
C. 1,225 cm
D. 70 cm

Answers

A rhombus has a total of 4 sides. All sides are equal. The formula of getting the perimeter of a rhombus is:
Perimeter = 4 * S
Perimeter = 4 * 35 cm
Perimeter = 140 cm.

So the perimeter of a rhombus-shaped street sign that has a 35-cm side is equal to (B) 140 cm.

What are ratios and proportions?

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.

Given that Kelly has 15 blue bracelets and 12 green bracelets. The ratio of the 15 blue bracelets and 12 green bracelets is calculated as:-

Ratio = blue bracelets / green bracelets

Ratio = 15 / 12

Ratio = 5 / 4

Hence, 12 green bracelets and 15 blue bracelets are distributed in a 5:4 ratio. The right answer is D.

HELP PLSS WHICH ONE IS IT!!Question 7 (3.03): Use the graph representing bacteria decay to estimatethe domain of the function and solve for the average rate of change across
the domain.

Answers

Answer:The domain of a function is the set of input values of the function.

The domain of the function is: [0,18]

The average rate of change across the domain is -3.33

Step-by-step explanation:From the graph, we have the following highlights.

The graph starts from the origin

The graph ends at x = 18

So, the domain of the function is: [0,18]

The average rate of change is calculated as:

From the graph, we have:

So, we have:

This gives

Hence, the average rate of change across the domain is -3.33

432 ft^2

Step-by-step explanation:

Answer:

432

Step-by-step explanation:

Lets plug it into the formula

b1 should be the horizontal line on the bottom horizontal line and b2 should be the top horizontal line

so we get b1 = 28 and b2 = 20

according to the formula we should add b1 and b2, getting us 48.

divide 48 by 2: we get 24

24 times h, or the hieght, or 18 is 432

so the answer is 432
