Answer:

x = 8

Step-by-step explanation:

The marked angles are alternate interior angles, so are congruent.

8x -4 = 60

8x = 64 . . . . . . . . . . add 4 to both sides

x = 64/8 = 8 . . . . . . divide both sides by 8

The value of x is 8.

Answer:

96º

Step-by-step explanation:

The sum of a triangle's angles is 180. We can find t by subtracting 58 and 38 from 180. 180-58-38=84. x and t and supplementary angles, so x is 180-t which is 180-84=96º.

Answer:

[tex]x + 2x + 24 = 180 \\ 3x = 180 - 24 \\ 3x = 156 \\ x = 52[/tex]

Answer: x = 52° and 2x + 24 = 128°

Steps:
180 = x + (2x + 24)
180 = x + 2x + 24
180 = 3x + 24
180 - 24 = 3x
156 = 3x
52 = x

Find the area of the shaded region. Round your answer to the nearest tenth if needed.

Answers

Answer:

140 inches

Step-by-step explanation:

Find the area of the square.

4 + 10 = 14 (Length)

11 + 4 = 15 (Breadth/Width)

Area = 14 x 15 = 210 inches

Find the area of the 2 unshaded squares in the square.

Area of square at the top = 4 x 4 = 16 inches

Area of square at the bottom = 6 x 9 = 54 inches

Add the 2 squares of the area together.

16 + 54 = 70 inches

Now deduct the area of the huge box by the area of the 2 unshaded squares.

210 - 70 = 140 inches

Answers

Answer:

Step-by-step explanation:

Area of the unshaded region = 95/360 * 3.14 * (5*√2)^2

Area of the unshaded region = 95/360 * 3.14 * 50

Area of the unshaded region = 41.43

Area of the entire circle = pi r^2

Area of the entire circle = 3.14 * (5√2)^2

Area of the entire circle = 157

Area of the shaded part = The whole circle's area - the unshaded part

Area of the shaded part = 157 - 41.42

Area of the shaded part = 115.57

this is tricky b/c they are making the two triangles of different scales but of the same angles.... soooo one is just a bigger copy of the other....

Step-by-step explanation:

Since this is a relation of the two side of each.. we can say the following...

[tex]\frac{6}{9}[/tex] = [tex]\frac{4}{x}[/tex] where X = side LA soooo solve for X

x * [tex]\frac{6}{9}[/tex] = 4 (move the X , to the other side of the '=' sign

x = 4 * [tex]\frac{9}{6}[/tex] ( yes.. we want to invert the fraction to move it to the other side )

x = [tex]\frac{36}{6}[/tex]

x = 6

so side LA is 6 :)

Well, "b" is just a variable. It's not really the function. I'm not quite sure what your asking. It can't be 1 because it can't. Math was founded on these mathematical laws. Consider talking to your teacher about this for further explanation.

An initial deposit of $1,000 is made into a savings account that is compounded continuously at 3% interest. How much money will be in the account after 18 years?

Answers

Answer:

$1700

Step-by-step explanation:

Given data

Principal P=$1000

Rate r= 3%

Time T= 18years

Required

The final amount A

The expression for the compound interest is

A= P(1+r)^t

substitute

A=1000(1+0.03)^18

A=1000(1.03)^18

A= 1000*1.70

A=$1700

Hence the final amount after 18 years is $1700
