Hello there, and thank you for asking your question here on brainly.

<em><u>Short answer: B. 0.71
</u></em>

<em>Why?
</em>

To find probability, you have to divide both the total number of possibilities, (7) and divide that by the greatest number of possibilities. (5). <em>5/7 </em>≈ <em>0.71

Hope this helped you! ♥</em>

Answer:

<1 = 114° and <2 = 66°

Step-by-step explanation:

The two angles measure 66 degrees and 114 degrees because the sum of supplementary angles is 180 degrees.

Explanation:

Supplementary angles are two angles with a sum of 180 degrees.

Let the smaller angle = x

If the two angles differ by 48 degrees, the bigger angle is 48 degrees more and equals

x+48

.

The sum of the two angles is 180, so...

x+x+48=180

Add the variableterms

2x+48=180

Subtract 48 from both sides

2x=132

Divide both sides by 2

2x/2=132/2

x=66

This is the measure of the smaller angle.

The bigger angle = x+48=114

A baseball team wants to collect at least 160 cans of food for an upcoming food drive. Team members brought 42 cans of food on M
Irina18 [472]
If they collect 65 on Monday, 42 on Wednesday and the rest on Friday, then we can write it down as:

65 + 42 + x ≥ 160
107 + x ≥ 160                 / - 107 (both sides)
x ≥ 53

So the team needs to collect at least 53 cans on Friday.
