Answer:

CDE = 10

Step-by-step explanation:

in parallelogram, adjacent angle are supplementary.

A+ B = 180

100 + B = 180

B = 180 - 100

B = 18

E ≅ B

E = 80

EC⊥ DC

DCE = 90

in ΔDCE,

DCE + CED + CDE= 180 {Angle sum property of triangle}

90 + 80 + CDE = 180

170 + CDE = 180  

CDE = 180 - 170

CDE = 10

Answer:

$32.1

Step-by-step explanation:

First find out what 25% of 40 is:

$40 x .25 = $10

Take the answer and subtract that from the original price:

$40 - $10 = $30

Next, take the sales tax (7% or 0.07) and multiply that by the new price:

$30 x 0.07 = $2.1

Lastly, take the answer and add that to the new price:

$30 + $2.1 = $32.1

Then you would get your answer:

$32.1

Answer:

120 ohms

Step-by-step explanation:

Given data

Voltage= 60 volts

Current= 0.5 amps

Power of bulb= 60 watt

We know that from Ohms law

V= IR

Make R subject of the formula

R= V/I

R= 60/0.5

R= 120 ohms

Hence the resistance is 120ohms

Answer:

OL = 128.2

Step-by-step explanation:

If the two quadrilaterals are similar, the ratio of their corresponding sides are equal;

Thus;

KJ/KH = NO/OL

19/42 = 58/OL

OL = (42 * 58)/19

OL = 128.2

Answer:

Step-by-step explanation:

A line is expressed as y=mx+b where m=slope and b=y intercept. As long as we have two points we can solve the equation of that line.

y=mx+b

For the top line I found two points (5,200) and (30,325)

m=(y2-y1)/(x2-x1)=(325-200)/(30-5)=125/25=5

y=5x+b, using point (5,200) we can solve for b

200=5(5)+b, b=200-25=175 so the line is

y=5x+175

For the bottom line we have points (5,50) and 10,100)

m=(100-50)/(10-5)=50/5=10

y=10x+b, using point (5,50) we have

50=10(5)+b, b=50-50=0 so

y=10x

Answer:

x=11°

<Bec = 33°

<Ced = 39°

Step-by-step explanation:

That's a right angle so it would be 90 degrees angle.

18+3x+4x-5=90

Lets simplify it to make it easier to work out by collecting like terms.

First all the variable 3x+4x=7x

Then the numbers 18+-5=13

13(-13)+7x = 90(-13)take away 13 from both sides

(Opposite operators EG, Add becomes subtract)

7x = 77 then divide 7 from both sides

x=11

Then work out

3x11=33 degrees

4x11=44-5=39 degrees

To double check 39+33+18=90 degrees

Answer:

D = 18 miles

Step-by-step explanation:

The coordinate of a library = (4,3)

The coordinate of the school = (-5,3)

We need to find the distance between the library and the school. We can use the distance formula i.e.

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\=\sqrt{(-5-4)^2+(3-3)^2}\\\\=\sqrt{81}\\\\=9\ miles[/tex]

As the distance between each unit represents 2 miles. It means the distance is 2(9) = 18 miles

So, the correct option is (c).

Answer:

70

Step-by-step explanation:

since you are solving for the middle angle, you solve for the average for both angles on the side

(112+28)/2=70

x=70

Well-designed child care centers typically have approximately 100 square feet per child of space in the overall center. So for example, a center proposing to serve 80 children would be likely to need a building that has about 8,000 square feet of total space available.

Answer: 2b+12

Step-by-step explanation:

Because the number is in front of the bracket you have to times everything in the bracket by the number on the outside.

So,

2 times b is 2b

And

2 times 6 is 12

So it would be 2b+12

Answer:

CE = 21 units

Step-by-step explanation:

Since, D is between Cand E (C - D - E)

Therefore,

CE = CD + DE

8x + 5 = 4x + 1 + 6x

8x + 5 = 10x + 1

8x - 10x = 1 - 5

-2x = - 4

2x = 4

x = 4/2

x = 2

CE = 8x + 5 = 8*2 + 5 = 16 + 5 = 21 units

Answer:

18.6inches

Step-by-step explanation:

Given the length of a side of a pentagon to be 6 inches.

If this length is dilated by a factor of 3.1, the new length will be;

New length = Old length * dilation factor

New length = 6 * 3.1

New length = 18.6inches

Hence the length of each side of the dilated pentagon is 18.6inches
