Answers

Answer:

10  

Step-by-step explanation:

5x - 20 = 2x + 10

subtracted 2x on both sides

3x - 20 = 10

then add 20 to both sides

3x = 30

then divide 3 on both sides

x= 10

Angle E and Angle F are Vertical Angles, If measure of Angle E is 3x + 33 and the measure of Angle F is 4x + 8, what is the value of x?

Answers

Answer:

Remember vertical angles are congruent so you can set these expression equal to each other and then solve the equation.

Angle F = angle E

4x + 8 = 3x + 33

Now solve for the x variable.

Find WX, ST = 10x + 5, WX = 7x + 8, UV = 8x - 1

Answers

Answer:

WX=29

Step-by-step explanation:

ST=10x+5

WX=7x+8

UV=8x-1

since SW=UW, WX is centered between UV and ST

(10x+5)-(7x+8)=(7x+8)-(8x-1)

3x-3=-x+9

4x=-12

x=3

substitute

WX=7(3)+8=29

Help me please

Answers

Answer:

11

220/x=100/5

(220/x)*x=(100/5)*x       - we multiply both sides of the equation by x

220=20*x       - we divide both sides of the equation by (20) to get x

220/20=x

11=x

x=11.

Solve using proportions.

The triangles are similar, find the length of side (k) using a proportion; having ratios within the two figures.

Note: If someone could please answer before this upcoming Monday.​

Answers

Answer:

7.8 = k

Step-by-step explanation:

Since the figures are similar, we can use proportions

c           k

----- = -------

b            j

Substituting the values in

6.5         k

----- = -------

4          4.8

Using cross products

6.5 * 4.8 = 4k

31.2 = 4k

Divide each side by 4

31.2/4 = 4k/4

7.8 = k

Write the slope-intercept equation of a line parallel to y = 3x + 2 that
contains the point (2, 1). SHOW ALL WORK.

Answers

Parallel lines have the same slope, in this case 3.

To find the y intercept we plug in the points (2,1) into y=mx+b, with 2 being x and 1 being y.

1=3(2) + b
Solve this and you get -5 as the y intercept.

The equation is y=3x-5

what is 512.3 divided by 10

Answers

Answer:

51.23

Step-by-step explanation:

Hi !

So basically all you need to do with an equation like this move the decimal.

And the direction you move it depends on the value of the largest digit as well as if it is larger or smaller than 0.

So lets look at 10 and make it 10.0 so its a decimal and make things a bit easier.

So 10.0 is just one digit moved in the decimal world. (100.0 would be 2, 1000.0 would be 3, and so on.)

And 10.0 is greater than 0.

Greater than 0 = Move decimal left

Less than 0 = Move decimal right

So now we know to move one space to the left.

512.3

>

One to the left

>

51.23

And its that easy, that is your answer.

I hope this helps!

Answer:

  sin(θ) = -√2/2

  tan(θ) = -1

Step-by-step explanation:

The reference angle is arccos(√2/2) = 45°. The sine has the same magnitude, so the tangent (ratio of sine to cosine) has a magnitude of 1.

The angle is given as a 4th-quadrant angle. Both the sine and tangent are negative in the 4th quadrant.

  sin(θ) = -√2/2

  tan(θ) = -1

In the attachment, the angle of interest is 315° (7π/4). The given unit-circle coordinates are ...

  (x, y) = (cos(θ), sin(θ))

  tan(θ) = y/x

sin(θ) = -√2/2

They need to first decide on the planning period (the benefits should be calculated over N years, and N should be determined). If N is too large, then the future benefits in those years (e.g. 70 years from now) will have a very low present value. Therefore, the engineer would like to cut off the planning period after a point when the present equivalent of benefits becomes less than 6.25% of that future benefit. If the interest rate is 8%, use the rule of 72 to determine the duration of the planning period (N). Simplify the expression 3y + 7 + 4y + 3.
