Answer:

[tex]\Huge\boxed{B.18.610}[/tex]

Step-by-step explanation:

Hello There!

We can find y by using trigonometric ratios

sine, cosine and tangent

[tex]tan= \frac{opposite}{adjacent}[/tex]

the opposite of the angle that has a measure of 28 degrees is y and the side that is adjacent to the angle is 35

so...

[tex]tan28=\frac{y}{35}[/tex]

now we solve for  y using basic algebra

we want to isolate the variable (y) using inverse operations

to get rid of the 35 we multiply each side by 35

[tex]\frac{y}{35} =y\\tan28*35=35tan28[/tex]

now we let the calculator do the rest of the work

[tex]35tan(28)=18.60983011[/tex]

*round to the nearest thousandth*

we're left with

y = 18.610

hence your answer is B

Answer:

Smallest to largest:

The circle with a diameter of 19

The circle with a circumference of 87.92

The circle with the area of 1,040.09

The circle with the radius of 27

Step-by-step explanation:

-The formula for the area is pi x r^2

-The diameter is double the radius, meaning divide it by 2 to get the radius.

-The formula for a circumference is 2 x pi x r meaning, do the reverse to get the radius. (87.92 divided by pi and then by 2 gives you the radius.)

-pi is equal to 3.14

haha my teacher saw my screen ( since im in-school ) and he said that you were a trapezoid

i would have answered this question in more detail but i didnt know how to, hope this help tho! :)

Answer:

Step-by-step explanation:

36 = 6* 6 = 2* 3 * 2* 3 = 2*2*3*3

180 = 2 * 2 * 3 * 3 * 5 = 2 * 2 * 3*3*5

[tex]\frac{36}{180}= \frac{2*2*3*3}{2*2*3*3*5} = \frac{1}{5}[/tex]

Answer:

226.08 cm^3 since volume

Step-by-step explanation:

Answer:

452.39

Step-by-step explanation:

The formula for volume is V=πr2h so you would add your numbers in and multiply (V=πr2h=π·42·9≈452.38934)

Answer:

42.84cm

Step-by-step explanation:

The perimeter is the sum of all the side length and the circumference of the semicircle

circumference of the semicircle = 2πr/2 = πr

circumference of the semicircle = 3.14 * (12/2)

circumference of the semicircle = 3.14 * 6

circumference of the semicircle = 18.84cm

Perimeter of the figure = 10cm + 6cm + 8cm + 18.84cm

Perimeter of the figure = 42.84cm (to nearest hundredth)

Answer:

$11,000

Step-by-step explanation:

1st year the account earned 20% from $25,000 = $5,000 | total = $30,000

2nd year the account earned 20% from $30,000 = $6,000

by adding the earnings of 2 years, she will be able to spend $5,000 + $6,000 = $11,000

Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex]\sqrt[3]{x+4}+\sqrt[3]{2x +8}=0\\\\\sqrt[3]{x+4}= -\sqrt[3]{2x + 8}\\\\(x +4)^{\frac{1}{3}}=-(2x+8)^{\frac{1}{3}}\\\\[/tex]

Take cube,

[tex][(x+4)^{\frac{1}{3}}]^{3} =- [(2x +8)^{\frac{1}{3}}^{3}]\\\\(x+4)^{3*\frac{1}{3}}=-(2x + 8)^{3*\frac{1}{3}}\\\\[/tex]

x + 4 = - (2x + 8)

x +4 = 2x *(-1) + 8 *(-1)

x+ 4 = -2x - 8

x +2x+4 = - 8

3x + 4 = - 8

      3x = - 8 -4

      3x = -12

        x = -12/3

x = -4
