PLEASE HELP!! WHAT IS x???

Answers

Answer:

  x = 90 degrees

Step-by-step explanation:

There are several ways to go about this (as is often the case with math problems). Here, we'll use the fact that an inscribed angle is half the measure of the arc it intercepts.

  arc DE = 2×∠DFE = 60°

  arc EF = 2×∠ECF = 60°

  arc CF = 2×∠CEF = 60°

Then arc DEC is ...

  arc DEC = arc DE +arc EF +arc FC = 60° +60° +60° = 180°

Angle DBC is half the measure of this arc, so is ...

  ∠DBC = 180°/2 = 90° = x

Answers

Answer:

length: 50 ydwidth: 40 yd

Step-by-step explanation:

The perimeter is twice the sum of length and width. Then the sum of length and width is 90 yards. Their product is the area, so we have ...

  x(90 -x) = 2000 . . . . where x is length or width

  x^2 -90x +2000 = 0 . . . . rearrange to standard form

  (x -40)(x -50) = 0 . . . . . . . factor

  x = 40  or  x = 50

The dimensions of the rectangular plot are 40 yards by 50 yards.

Identify the slope and y-intercept for the linear equation below.
y = 1/3x+7

Answers

Answer:

Slope is 1/3.

Y-intercept is 7.

Step-by-step explanation:

y = mx + b is the slope-intercept form.

m = slope

b = y-intercept

In the equation, y = 1/3x + 7

m = 1/3

b = 7

Therefore, slope is 1/3 and y-intercept is 7.

Hope this helped! <3

Answer:

Slope is 1/3 and the y- intercept is 7

Step-by-step explanation:

Since the equation is y = mx+b, we know that 1/3 is the slope since m represents the slope and b represent the y-intercept, meaning 7 is the answer.

Part B 1/2-5/8-7/9=7/9-5/8-1/2

Answers

Answer:

False

Step-by-step explanation:

1/2 - 5/8 - 7/9 = 7/9 - 5/8 - 1/2

Add 5/8 to both sides.

1/2 - 7/9 = 7/9 - 1/2

Factor -1 out of the right side.

1/2 - 7/9 = -1(-7/9 + 1/2)

1/2 - 7/9 = -1(1/2 - 7/9)

1/2 - 7/9 and 7/9 - 1/2 are opposites. Opposites are not equal unless they are both zero.
