A sprinkler is set to water the section of lawn represented by the shaded region in the circle below. which measurement is closest to the area of the lawn watered by this sprinkler
Answers
Answer:
A = 64.141
Step-by-step explanation:
150/360 = 0.41667
41.667% of the circle is shaded so when we find the area we will multiply ir by 0.41667 to find only the shaded area
A=πr^2 x 0.41667
A = π(7)^2 x 0.41667
A = 64.142
The area of the lawn watered by this sprinkler is 64 square feet.
What is area of a sector?The area of a sector is the space inside the section of the circle created by two radii and an arc. It is a fraction of the area of the entire circle.
The formula to find the area of a sector = θ/360° ×πr².
From the given circle, central angle is 150° and the radius of a circle is 7 feet.
Here, the area of a sector = θ/360° ×πr²
= 150°/360° ×3.14×7²
= 0.417×3.14×49
= 64.15962
≈ 64 square feet
Therefore, the area of the lawn watered by this sprinkler is 64 square feet.

14 = p + 19 I need some help with this one?
Answers
Answer:
p=-5
Step-by-step explanation:
have a lovely day!!
That is bc if +19 has a + u make it - so then u subtract.
So 19-14=15 to find the p.
P=15
If the 19 was -19 instead of +19 then u would do.
19+14= 43. Which would then be.
P=43.

A right cubic prism has edges of 2 1/2 inches. How
many cubes with side lengths of inches would
be needed to fill the prism?
A. 125 cubes
B. 37.5 cubes
C. 18.75 cubes
D. 15.625 cubes
Answers
Answer:
Option D, the volume is 15.625 cubes
Step-by-step explanation:
For a cube of side length L, the volume is:
V = L^3
for the smaller cubes, we know that each one has a side length of 1 in, then the volume of each small cube is:
v = (1in)^3 = 1 in^3
Then:
1 in^3 is equivalent to one small cube
Here we know that the side length of our cube is (2 + 1/2) in
Then the volume of this cube will be:
V = [ (2 + 1/2) in]^3
To simplify the calculation, we can write:
2 + 1/2 = 4/2 + 1/2 = 5/2
Then:
V = ( 5/2 in)^3 = (5^3)/(2^3) in^3 = 125/8 in^3 = 15.626 in^3
This means that 15.625 small cubes will fill the prism.
So the correct option is D.

If you deposit $4,000 into an account paying 5% annual interest compounded monthly, how
much money will be in the account after 10 years? Round your answer to two decimal places.
Answers
Answer:
6000
Step-by-step explanation:
start by finding what 5% of 4000 is by multiply 4000 by .05 then take that number times it by ten to find the amount accumulated over the ten years and add it to the deposit of 4000
4000 * .05 = 200
200 * 10 = 2000
2000 + 4000 = 6000

Answers
Answer:
p(blue or red) = 0.52 = 52%
Step-by-step explanation:
total number of marbles = 7 + 10 + 14 + 19 = 50
number of blue marbles = 7
number of red marbles = 19
number of blue or red marbles = 7 + 19 = 26
p(blue or red) = 26/50
p(blue or red) = 0.52 = 52%
Answer: 52%

7) Original price: ?
Discount: 25%
Sale price:
$28
Answers
Answer:
Step-by-step explanation:
let be x the price before the discount
original price= 28/(1-0.25)=28/0.75=37.33
original price=37.33
Answer:
37.3
Step-by-step explanation:
The original price = x which represents 100% of the price. So we subtract 100%-25, which is 100-25=75 or 75%(0.75)
So, $28 is 75% off the original price.
28 divided by .75 = 37.3
Then, 37.3 would be the original price.

A mailing supply company produces yellow mailing envelopes. The envelopes come in
a variety of sizes, but the length is always 4 centimeters more than double the width.
Write an equation to find the dimensions of an envelope that has a perimeter of 26
centimeters.
Answers
Answer:
Step-by-step explanation:
L=2W+4
P=2(L+W), using L from above makes this
P=2(2W+4+W)
P=2(3W+4)
P=6W+8
6W=P-8
W=(P-8)/6, since we are told P=26
W=(26-8)/6
W=18/6
W=3 cm, and since L=2W+4
L=2(3)+4
L=6+4
L=10 cm
So the dimensions of the envelope with a perimeter of 26cm is 3cm by 10cm

In triangle UVW, u = 20, v = 47. and w = 60. To find m∠ W,
which law would you use? Laws of Sines or Laws of Cosines? and why?
Answers
Answer:
We would use the Law of Cosines to solve the question.
m∠ W = 121.8°
Step-by-step explanation:
In triangle UVW, u = 20, v = 47. and w = 60. To find m∠ W,
which law would you use?
The Law we would use to find find m∠W is the Law of cosines, this is because in the question above we are given 3 known sides of a triangle and we are asked to find an unknown angle.
Law of cosines when we are to find an unknown angle =
m∠ W = arc cos [u² + v² - w²/ 2uv]
m∠ W = arccos [ 20² + 47² - 60²/ 2 × 20 × 47]
m∠ W = 121.81159°
Approximately = 121.8°
