Step-by-step explanation:

Answer:

Z=20 Degrees

Step-by-step explanation:

We know that all of the angles of a triangle add up to 180, so:

65+55+ Angle A = 180

Simplify:

120+ Angle A = 180

Subtract 120 from both sides:

Angle A = 60

If you look at the bottom you can see that the 15 turns into 5, meaning it is being divided by 3, so:

60/3=20

Z=20 Degrees

Answer:

Angle E is 60 degrees

Step-by-step explanation:

So z is an angle.

That would be point E.

This triangle was dilatated so we can match it up with the larger one. In a dilation, angle measures do not change. So matching up the points E would be equal to A, which of course it the only one with an angle measure not given.  

All you have to do is add up the two angle measures and subtract that by 180 (total of all angles combined).

So 65+55=120

180-120=60

Angle A is 60

Which makes angle E 60 as well

Hope that helps!

Answer:

Cost of 110 g bag = $ 0.132

Step-by-step explanation:

As we know ,

1 kg = 1000 g

⇒1000 g = 1 kg

⇒1 g = [tex]\frac{1}{1000} = 0.001[/tex] kg

⇒110 g = 110 (0.001) kg = 0.11 kg

⇒110 g = 0.11 kg

Now,

Cost of 10 kg bag = $12

⇒Cost of 1 kg bag = [tex]\frac{12}{10} = 1.2[/tex]

⇒Cost of 1 kg bag = $ 1.2

⇒Cost of 0.11 kg bag = $ (0.11)(1.2) = $ 0.132

∴ we get

Cost of 110 g bag = $ 0.132

Answer:

(0,35)

(1,50)

(2,65)

(3,80)

Y intercept: 35

Slope: 15

This means that it has an independent cost of $35 and a variable fee of 15

Step-by-step explanation:

It's near impossible for me to show you where the line goes and so I'm just going to give you five or so points

To get the 5 point just plug different x values in

(0,35)

(1,50)

(2,65)

(3,80)

The slope intercept equation looks like the following

y=mx+b

where b is the y intercept and m is the slope

this means our equation's slope is 15 and the y intecept

is 35

Answer:

The range is 28

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

A right angle means that the lines will create an L or X or T when they intersect. This is exactly the definition of perpendicular, that the shapes will intersect and create at least one right angle.

Answer:

If you ever see a little square at the corner of a shape, then you know that not only is this a right angle, and thus, 90 degrees, but that the two lines that form such an angle are perpendicular to one another. Squares and rectangles always have four right angles!

17=a+3+a

14=2a

7=a

b=3+7

b=10

10. 156.25/6.25= 25 hrs

Answer:

9. x = 7, y = 10

Step-by-step explanation:

9. I first set up an equation x+y=17

then I set up a second equation y = x+3

I substitute y for x+3 and get x+x+3=17 or 2x+3=17

then I just evaluate the equation x=7

I then use my first equation x+y = 17 and substitute the value 7+y= 17 and get y = 10

10. Just divide 156.25 with 6.25 to get the number of hours she had to work to get 156.25 dollars. The answer would be 156.25/ 6.25 = 25

Answer:cost for basket ball= $8 and

cost of baseball = $2

Step-by-step explanation:

Step 1

Let the cost of basket ball be represented as x

and cost of  baseball = y          such that

Four basketballs and six baseballs cost $44 will be expressed as

4x+ 6y= 44  --- eqn 1   also

Five basketballs and four baseballs costs $48 will be expressed as

5x+ 4y= 48--- eqn 2

Step 2

Having obtained two expressions we can now sole

4x+ 6y= 44  --- eqn 1

5x+ 4y= 48--- eqn 2

multiplying eqn 1 by 5 and eqn 2 by 4

20x+ 30y =220---- eqn 3

20x+ 16y=192-----eqn 4

subtracting equation 4 from 3   we now have

14y=28

y= 28/14

y=2 = $2

from equation 1

4x+ 6y= 44, putting the value of y=7 to find x

4x+ 6(2)= 44

4x+12= 44

4x= 44-12

4x=32

x= 32/4

x=8=$8

cost for basket ball= $8 and

cost of baseball = $2
