i need help on these questions i don't know about these

Step-by-step explanation:

1. Angle 5 = 120 degree

Angle 5 = Angle 6 ( alternate exterior angles are equal )

Therfore, Angle 6 = 120 degree

Angle 6 = Angle 4 ( Vertically opposite angles are equal )

Therfore, Angle 4 = 120 degree

Angle 4 = 5x

120 = 5x

120/5 = x

40 = x

Therefore x = 40 degree.

2. Angle 1 = 100 degree

Angle 1 = Angle 7 ( vertically opposite angles are equal )

Therefore, Angle 7 = 100 degree

Angle 7 = 10x

100 = 10x

100/10 = x

10 = x

Therefore x = 10 degree

I want some more time for this question.

y < -12

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

−2y − 8 > 16

Step 2: Add 8 to both sides.

−2y − 8 + 8 > 16 + 8

−2y > 24

Step 3: Divide both sides by -2.

−2y/−2 > 24/−2

y < −12

Answer:

y < −12

Step-by-step explanation:

                                                     −2(y + 4) > 16      

                                                               ↓

                                                      −2y − 8 > 16

                                                               ↓

                                                          y < −12

Step-by-step explanation:

Answer:

x = -4 and x = 5

Step-by-step explanation:

Since [tex]x^2 + 2x[/tex] and [tex]3x + 20[/tex] both equal to y, we know that the expressions equal to each other. We can write a new equation base on that.

[tex]x^2 + 2x = 3x + 20[/tex]

Now we solve the equation.

[tex]x^2 + 2x = 3x + 20[/tex]

[tex]x^2 - x = 20[/tex]

[tex]x^2 - x - 20 = 0[/tex]

[tex](x + 4) (x - 5) = 0[/tex]

[tex]x + 4 = 0 ; x -5 = 0[/tex]

[tex]x = -4 ; x = 5[/tex]

Answer:

1) 23^a+b

2) 5^5

3) 11^x-y

4) 2^10

Step-by-step explanation:

if they have the same base numbers then they are pretty easy to combine. multiplication means you add the exponents, and division means you subtract the exponents. for number 2, you would make them the same base by making 25 -> 5^2 and then just add the exponents.

2)     (0,-3)

Step-by-step explanation:

hello :

put x=0 and y= -3 in this system !

Y = 3/4x - 3

3x - 4y = 12

- 3 = 3/4(0) - 3  means : -3 = -3 ......true

3(0) - 4(-3) = 12  means : 12= 12 ......true

Answer:

its a. 475.26

Step-by-step explanation:

445/ 100= 4.45

4.45×3.4=15.13

15.13+445=460.13

460.13+15.13= 475.26

Answer:

A.The value of both expressions when t=3 is 33.

D.The value of both expressions when t=6 is 51.

E.The two expressions are equivalent.

Step-by-step explanation:

We are given two expressions.

3(2t + 5)

6t + 15

Now let's find the value of these two expressions when t =3 and t = 6

When t =3, the value of the expressions:

3(2*3 + 5) = 3(6 + 5) = 3(11) = 33

6*3 + 15 = 18 + 15 = 33

So the value of both the expressions is 33 when t = 33.

When t = 6, the value of the expressions:

3(2*6 + 5) = 3(12 + 5) = 3(17) = 51

6*6 + 15 = 36 + 15 = 51

The value of both the expressions is 51 when t = 51.

So the following statements are true:

A.The value of both expressions when t=3 is 33.

D.The value of both expressions when t=6 is 51.

E.The two expressions are equivalent.

Answer:

471

Step-by-step explanation:

Using Pi=3.14

First find the area of the bottom circle:

3.14*([tex]5^{2}[/tex])

=78.5

Then multiply the result by the height

78.5*6=471

therefore,

Volume of clylinder: 471 units squared

Explanation:

The quadrilateral will be a parallelogram if the diagonals bisect each other. That is, their midpoints are the same point. We don't actually need to calculate the midpoint. Rather, we can calculate the point that has double the coordinate values.

If (A+C) = (B+D), the quadrilateral is a parallelogram.

  A +C = B +D

  (-2, 8) +(5, 1) = (2, 7) +(1, 2)

  (-2+5, 8+1) = (2+1, 7+2)

  (3, 9) = (3, 9) . . . . . the figure is a parallelogram

_____

Of course, the midpoint of the diagonals is (3/2, 9/2).
