EMD = 90 - DMC
EMD = 90 - 20
EMD = 70

Now, DMB = 180 - FMD
DMB = 180 - 90
DMB = 90

Hope this helps!

Answer:

105

Step-by-step explanation:

$A=lw$ $A=$ (.5)πr²

to get the area of the shaded parts you have to subtract the area of the semicircle from the area of the rectangle

$A=(16)(9)$

$A=144$

$A=\frac{(3.14)(5)^2}{2}$ $A=\frac{(3.14)(25)}{2}$ $A=\frac{78.5}{2}$

$A=39.25$

subtract the areas

$144-39.25=104.75$

$104.75$ ≅ $105$

Sum of three consecutive multiples of 6 is 648. One of these multiple is

Ber [7]

Answer:

Let two consecutive multiples of 3 be x and (x+3)

A/q,

x * (x+3) = 648

➡ x² + 3x = 648

➡ x² + 3x -648 = 0

➡ x² + 27x - 24x -648 = 0

➡ x ( x + 27 ) -24 ( x +27)

➡ ( x - 24) ( x + 27)

➡ x = 24 and x = -27

so, we take x = 24.

Required multiples of 3

➡ x = 24

➡ x +3 = 24+3 = 27.

A piece of wire is 8/9 meter long broke into two pieces. One piece is 2/3 meter long. How long is the other?

Genrish500 [490]

Answer:

<h2>2/9 is the answer.</h2>

Step-by-step explanation:

1. First, make an equation.

Given:

8/9 = length of wire

2/3 = length of a part of the wire

E = 8/9-2/3

Unknown:

Second part of wire

2. Make the numbers have equal denominators

2/3 * 3/3

= 6/9

3. Solve

8/9 - 6/9

= 2/9

Which of the following relations is a function? A. (0, 4), (-2, 6), (0, 3), (-7, 2) B. (8, 1), (-2, 4), (0, 1), (8, 2) C. (0, 4)

fomenos

Answer: C

Step-by-step explanation:

C is a function because each of the inputs are distinct, meaning they only have one output each.

The other choices are not functions because at least one of the inputs corresponds to 2 or more outputs.
