Find the value of x ???????????? V

Answers

Answer 1

Step-by-step explanation:

By using formula of h^2=p^2+b^2

h=20

p=x

b=10

Now,

p=root h^2-b^2

x=root 20^2-10^2

x=root 400-100

x=root 300

x= 10root3

A fan oscillates 250* and can be felt from a distance of 4 feet away . To the nearest tenth what area of the room can feel the wind from the fan? Use 3.14 for pi .

Answers

Answer:

[tex]A=256.67ft^2[/tex]

Step-by-step explanation:

From the question we are told that:

Fan oscillates [tex]\theta=250[/tex]

Distance [tex]d=>Raduis\ r=4 feet[/tex]

Since

[tex]250\textdegree =180\textdegree +70\textdegree[/tex]

Generally the equation for the area A is mathematically given by

[tex]Area=Area\ of\ semi\ circle\ + area\ of\ 70\textdegree sector[/tex]

[tex]A=A_{sm}+A_{70\textdegree}[/tex]

Where

[tex]A_{sm}=\frac{1}{2} \pi r^2[/tex]

[tex]A_{sm}=\frac{1}{2} 3.14 4^2[/tex]

[tex]A_{sm}=25.12ft^2[/tex]

[tex]A_{70\textdegree}=\frac{1}{2}r^2 \frac{70\textdegree}{360\textdegree}[/tex]

[tex]A_{70\textdegree}=\frac{1}{2}*4^2* \frac{70\textdegree}{360\textdegree}[/tex]

[tex]A_{70\textdegree}=1.55ft^2[/tex]

Therefore the area A is given as

[tex]A=A_{sm}+A_{70\textdegree}[/tex]

[tex]A=25.12ft^2+1.55ft^2[/tex]

[tex]A=256.67ft^2[/tex]

Grace’s garden is shown below. She is going to buy bags of soil that cover 75 square feet each. How many bags of soil will she need for her entire garden? Use 3.14 for pi.

A. 4 bags

B. 5 bags

C. 6 bags

D. 7 bags

Answers

Answer: C. 6 bags

Step-by-step explanation:

To solve this, you need to calculate the area of every shape in the garden and then sum them up.

Semi circle:

Area of semi-circle = (π * radius²) / 2

Radius = Diameter/ 2 = 18/2 = 9 feet

Area = (3.14 * 9²) / 2

= 127.17 ft²

Rectangle:

= Length * Width

= 18 * 8

= 144 ft²

Triangle

= 1/2 * base * height

= 1/2 * 18 * 18

= 162 ft²

Added up:

= 127.17 + 144 + 162

= 427.17 ft²

If each bag covers 75 ft² each, the number of bags needed is:

= Area to cover / Coverage per bag

= 427.17 / 75

= 5.7

= 6 bags

Which equation represents the line that is perpendicular to and passes through (-6,-9)?
A.
x = -9
B.
x = -6
C.
y = -9
D.
y = -4

Answers

Answer:

y = -9

Step-by-step explanation:

Complete question;

Which equation represents the line y = 1/4 that is perpendicular to and passes through (-6,-9)?

The equation of the line in point slope form is y-y0 = m(x-x0)

Given the equation y = 1/4, the slope of the line is zero

Substitute the slope and the point into the formula;

y -(-9) = 0(x-(-6)

y + 9 = 0

y = -9

Hence the required equation is y = -9

Answer:

C.y = -9

Step-by-step explanation:

The probability that the first student walks to school will be: = 7/30.

The probability of selecting the second student that walks to school will be: = 6/29.

Then we multiply both together and this will be:

= 7/30 × 6/29

median of 22, 16, 14, 26, 32, 30

Answers

Answer:

Step-by-step explanation:

cancel out from the sides till you have 1 number in the middle but in this case we have 2 numbers.

in a case like that you add both numbers and divide by 2 to get your answer

so 16+14÷2= 15

Median is the middle

Since there is an equal amount of numbers,6, you would need to take the average of the two numbers in the middle.

REMEMBER: always put it in ascending order first (0-10)

14, 16, 22, 26, 30, 32

Middle numbers are: 22 and 26

Take average: (22+26)/2 = 24

Therefore the median of this sequence is 24.
