Answer:

y = 15

Step-by-step explanation:

angle poq + angle qor equals mpor (120)

4y + 3y + 15= 120

7y+15=120

subtract 15 from both sides

7y=150

divide both sides by 7

y=15

check:

4(15) + 3(15) + 15 equals 120

60 + 45 + 15 = 120

120 = 120

Emi made a 90 on her math test. There was 60 problems on her test. How many did she miss?
viva [34]
If she made a 90 that means 90 percent aka .90 so multiply that by 60 to get 54 right aka 6 wrong which you could find either by subtracting 54 from 60 or solving for 10 percent bc she got that much wrong and multiply .10x60=6 wrong

Please help.
kirill115 [55]

we have

y=-16t^{2} +120

we know that

When the apple hit the ground the value of y is equal to zero

so

Find the x-intercept of the function

equate the function to zero

-16t^{2} +120=0

Group terms that contain the same variable, and move the constant to the opposite side of the equation

-16t^{2} =-120

t^{2} =-120/-16

t^{2} =7.5

t=(+/-)\sqrt{7.5}

t=(+/-)2.74

therefore

<u>the answer is</u>

2.74\ sec

using a graphing tool

see the attached figure to better understand the problem
