At the time that a 55 foot tall tree casts a shadow that is 32 feet long, a nearby woman is 5.5 feet tall. Which measure is the

Tasya [4]

Answer:

3.2ft long shadow

Step-by-step explanation:

In this problem we are given a ratio between the tree/shadow and woman/shadow therefore we are given 3 values and 1 unknown then we can use the Rule of Three to calculate the length of the shadow which we will refer to as x. The Rule of Three simply multiplies the diagonal values and divides by the third value in order to get the missing unknown like so...

55ft tall <======> 32ft long shadow

5.5ft tall <======> x ft long shadow

(5.5 * 32) / 55 = 3.2ft long shadow

Finally, we can see that the woman's shadow would be a 3.2ft long shadow

Factor completely 2r²-32

diamong [38]

Answer:

2(r+4)(r-4)

Step-by-step explanation

First, you want to factor out 2 from both terms, which gives you 2(r^2-16). Then you want to recognize that (r^2-16) is factorable into 2 terms. If you multiply (r+4) by (r-4) then you are given (r^2-16) as a result.

Tenaya earned 82 points on one math test and 94 points on the next test. Elena earned 94 points on the first test and then 82 po

jek_recluse [69]

Answer:

Total test score of Tenaya and Elena are same.

Step-by-step explanation:

Given:

Points earned by Tenaya on one math test = 82

Points earned by Tenaya on next math test = 94

Points earned by Elena on first math test = 94

Points earned by Elena on next math test = 82

We need to Compare the total test scores for Tenaya to the total scores for Elena.

Solution:

First we will find the Total test score of Tenaya and Elena.

Now we can say that;

Total test score of Tenaya is equal to sum Points earned by Tenaya on one math test and Points earned by Tenaya on next math test.

framing in equation form we get;

Total test score of Tenaya = $94+82 = 176\ points$

Total test score of Elena is equal to sum Points earned by Elena on one math test and Points earned by Elena on next math test.

framing in equation form we get;

Total test score of Elena = $94+82 = 176\ points$

Hence from we can say that Total test score of Tenaya and Elena are same.

What is the equation, in slope-intercept form, of the line that passes through the points (−24, 5) and (16, −20)?

ser-zykov [4K]

Answer:

C (Y = -5/8x - 10)

Step-by-step explanation:

first find the slope (y₂ - y₁) ÷ (x₂ - x₁)

(5 - (-20)) ÷ (-24 - 16)

-5/8 = slope (m)

now that we know the slope is -5/8 we can rule out A and B

now to find the y intercept just substitute a point in for x and y

5 = (-5/8)(-24) + b

multiply

5 = 15 + b

subtract 15 from both sides tp isolate b

-10 = b
