Answer:

41°

Step-by-step explanation:

The angle below (2x-5) is also 113° (which i hope you know why)

Then to find (2x-5)° you would subtract 180 - 113 to get the angle because both those angles would add up to 180° because it is a straight angle which gives you 67°

Then you need to find x by solving the equation 2x - 5 = 67 which would give you x = 36, so you would multiply that by 2 for the angle on the side which would be 72°

Then bc the angles on the inside of the triangle all add up to 180° as well, you would add 72 + 67 = 139, then do 180 - 139 giving you d° as 41°

Answer:

41º

Step-by-step explanation:

Because of parallel lines, (2x-5)º=180º-113º, so (2x-5)º=67º.

  • (2x-5)º=67º
  • 2x-5=67º
  • 2xº=72º
  • x=36º

The angle that says (2x)º will be (2[36])º=72º.

So the other angle will be 180-67-72=41º as the sum of a triangle's interior angles is 180º.

Tyler went to the supermarket to buy food for a food pantry. He has $36, and can carry up to 20 pounds of food in his backpack.
Inessa [10]

Answer:

1,12/ Not a solution

2,10/ solution

4,5/ solution

6,10/ not a solution

12,8/ not a solution

18,6/ not a solution

Step-by-step explanation:

all you have to do is put it into the equation.


for example:

1,12

1x1+12x3= $37

1x1+12x1.5= 19lbs

This is not a solution because he can carry it but doesn't have the money to buy it.

A researcher is interested in determining whether teens who transfer schools after their freshman year in high school demonstrat
Kay [80]

The z-score of the number of teens that transfered schools is the standard score

The obtained value of z is 5

<h3>How to determine the value of z?</h3>

The given parameters are:

  • Population mean, μ = 50
  • Population standard deviation, σ = 10
  • Sample, x = 100
  • Sample mean = 59

The z-value is calculated using:

z = (x - μ)/σ

Substitute known values in the above formula

z = (100 - 50)/10

Evaluate the difference

z = 50/10

Evaluate the quotient

z = 5

Hence, the obtained value of z is 5

Find the total area of the prism.<br><br> 144 sq. in.<br> 576 sq. in.<br> 864 sq. in.
anastassius [24]

Answer:

864\ in^{2}

Step-by-step explanation:

The figure is a cube

The surface area of a cube is equal to

S=6b^{2}

where

b is the length side of the cube

In this problem we have

b=12\ in

substitute

S=6(12^{2})=864\ in^{2}
