Answer:

133

Step-by-step explanation:

The two angles add to a straight line

PQR + RQS = PQS

3x-5 + x+1 = 180

Combine like terms

4x -4 =180

Add 4 to each side

4x -4+4 = 180+4

4x =184

Divide each side by 4

4x/4 =184/4

x =46

We want to find PQR

PQR = 3x-5

      = 3*46 - 5

    = 138 -5

    = 133

It would be 133

3x-5+1x+1=180
X= 46 and to check you could plug x into each equation which adds to 180.

In a school 40% are boys and 900 are girls. find the total number of students of the school and the number of boys
My name is Ann [436]

Answer:

1500 students

600 boys

Step-by-step explanation:

40% are boys, so 60% are girls.

Writing a proportion:

900 / 60% = x / 100%

x = 1500

There are 1500 students in the school, which means there are 600 boys in the school.

paula spent 3/8 of her allowance on clothes and 1/6 on entertainment. what fraction of her allowance did she spend on other item
MArishka [77]
We have to calculate the fraction of Paula`s allowance that she spent on other items if she already had spent 3/8 on clothes and 1/6 on entertainment. First we have to add: 3 / 8 + 1 / 6 = ( LCD is 24 ) = 9 / 24 + 4 / 24 = 13 / 24. Then : 1 - 13 / 24 = 24 / 24 - 13 / 24 = 11 / 24. Answer: She has spent 11 / 24<span> of her allowance on other items. </span>

Your customer is located 100 miles from your office.
OlgaM077 [116]

Answer:

8:02 AM

Step-by-step explanation:

Find out how many minutes it takes to travel one mile:

60 divided by 45= 1.333334 minutes

It takes 1.333334 minutes to travel 1 mile, how long will it take to travel 100 miles:

1.333 times 100 = 133.3334

133.3334 rounds to 133 minutes

Add 15 minutes because you want to arrive early

133+15=148

Divide it by 60

148 divided by 60 = 2.466667

or do

148-120 (2 hours) = 28 minutes

It will take 2 hours and 28 minutes to get there

10:30-2:28= 8:02

Step-by-step explanation:

d=v_ot+\dfrac{1}{2}at^2 \\\\d=(300)(4)+\dfrac{1}{2}(-32)(4)^2 \\\\d=1200-256=944
