Answer:

b) 36

Step-by-step explanation:

ratio of angles = 3:5:7

The angles are 3x, 5x , 7x

Sum of all the three angles of triangle = 180

3x + 5x + 7x = 180

15x = 180

x = 180/15

x = 12

Measure of smallest angle = 3x = 3*12 = 36

Find the widest range of scores that you can get on a final exam in order to receive a grade of B for the class. Using interval

Drupady [299]

Answer:

Correct choice is B

Step-by-step explanation:

Let x% be your final test score, then the average of all test scores is

$\dfrac{96+77+74+x}{4}.$

Since you must have an average between 80% and 89%, then

$80\le \dfrac{96+77+74+x}{4}\le 89,\\ \\320\le 247+x\le 356,\\ \\73\le x\le 109.$

X is measured in percent, then the greatest value of x can be 100%. You get that

$73\%\le x\le 100%.$

Ryan spent $26.32 on 8 gallons of gas. How much would he spend for 20 gallons?

Nana76 [90]

Answer:

$65.80

26.32÷8=3.29

So it's 3.29 per gallon.

Multiply 3 29 by 20.
