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 .
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]

A school survey found that 7 out of 30 students walk to
school. If two students are selected at random without
replacement, what is the probability that both students
walk to school?
49/90
49/900
7/30
7/145
Answer: 7/145
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
= 7/145

Write the piecewise function for the graph.
Answer:
In the picture
Step-by-step explanation:
First, find a function for each line.
-2x - 2 fits the green line because for every x value, y is -2(x) - 2.
2x + 1 fits the red line because for every x value y is 2(x) + 1.
You also need to include "if." -2x -2 if x < 0.
For the red line, the dot is closed so if x ≥ 0.

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
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 = -9Step-by-step explanation:

Step-by-step explanation:
sin 42° = 12/x
x = 12/sin 42°
x = 17.9
Answer:
17.9
Step-by-step explanation:
> sin 42° = 12/x
> x = 12/ sin 42°
> x = 17.9

Ms. Powell bought 12 cookies for $4.00 and Ms. Malley bought 8
cookies for $3.50. How much did each person pay for a cookie? And who
had the better deal?
Answer:
Ms. Powell paid around 33 cents for each cookie
Ms. Malley paid around 43 cents for each cookie
Ms. Powell had the better deal
Step-by-step explanation:
Divide the amount paid with the amount of cookies bought so 4 ÷ 12 = 0.3333... and 3.50 ÷ 0.4375...
I hope this helped!
1) Approximately ¢33 per cookie
2) Approximately ¢29 per cookie

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
find the area of the irregular figure. PLEASE!!
The sides are: 3 in, 4 in, 4 in, 5 in, 7 in, 9 in
geometry
Answer:
A = [84]in^2
Step-by-step explanation:
5 x 3 = 15
4 x 2 = 16
9 + 4 = 13 x 4 = 52
52 + 15 + 16 = 84in
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
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
