Answer:
254 inches squared
Step-by-step explanation:
Hi there!
[tex]A=\pi r^2[/tex] where r is the radius of the circle
The radius is equal to half the diameter. Given that the diameter is 18 inches, we know that the radius of the circular plate is 9 inches. Plug this into the equation:
[tex]A=\pi (9)^2\\A=81\pi \\A=254[/tex]
Therefore, the area of the plate is approximately 254 inches squared.
If this is not an answer choice, the question may have been asking for the radius of the circle rather than the area.

Answer:
49
Step-by-step explanation:
4^3=64
5(-3)=-15
64+(-15)=49
Answer:
49
Step-by-step explanation:
First, because of the order of operations, you would do 4^3 (or four to the power of three) first to get 64. 5×-3 is equal to -15, and a positive number plus a negative number is just that positive number minus a positive version of the negative number, if that even makes sense. Basically, 35 + -2 would be equal to 35-2. 64-15 is equal to 49, which is your answer!
I hope this helped you!

Jim is repainting a free-throw key of a basketball court. the free-throw is made by combining a rectangle and a semicircle, as shown below. In order to know how much paint to purchase, Jim will determine the area of the free-throw key. What is the total area, to the nearest whole square foot, of the free-throw key shown in the diagram?
Answer:
285
Step-by-step explanation:
First find the area of the rectangle
A = l*w
A = 19*12 = 228
The find the area of the semicircle
A = 1/2 pi r^2
We know the diameter is 12 so the radius is half the diameter so 1/2 (12) = 6
A = 1/2 (3.14)(6)^2
= 1/2 (3.14) (36)
= 56.52
Add the two areas together
225+56.52
284.52

Two runners are participating on a 720-metre circular track. They run in opposite directions, each at a constant speed. The first runner needs four minutes to complete the full loop and the second runner needs five minutes. How many metres does the second runner travel between two consecutive meetings of the two runners?
Happy Pride Month!
Answer:
320m
Step-by-step explanation:
let the two runners be A and B
with Va and Vb as their velocities
velocity=distance/time
Va=720/4*60
=3m/s
Vb=720/5*60
=2.4m/s
Let the 2 runners start from a common position X and meet at Y
so the 2 consecutive meetings happen at X and Y
so we have to find time of meeting at Y as we know that of X (which is t=0)
720=Va*t+Vb*t
t(5.4)=720
t=133.33 or t=720/5.4
therefore distance travelled by B =Vb*t
=2.4*720/5.4
=319.99m
=320m

a man in a boat rowing from light house whose height is 200 meter.he takes 2minutes to change the angle of elevation top of light house from 60⁰ and 45⁰ find speed of boat
Answer:
The speed of the boat is approximately 0.704 m/s
Step-by-step explanation:
The time it takes the man in the boat to change the angle of elevation from 60° to 45°, t = 2 minutes = 120 seconds
The height of the light house = 200 m
Given that the angle of elevation is reducing, the direction of the man is away from the lighthouse
The initial distance of the man in the boat from the lighthouse = 200 m/(tan(60°)) = (200/√3) m
The final distance of the man in the boat from the lighthouse = 200 m/(tan(45°)) = 200 m
The distance traveled in 2 minutes, d = 200 m - (200/√3) m ≈ 84.53 m
The speed of the boat, v = d/t
∴ v = 84.53 m/(2 min × 60 s/min) ≈ 0.704 m/s
The speed of the boat, v ≈ 0.704 m/s.

[tex]Volume~of~cylinder=\pi r^2h[/tex]
[tex]\pi *(10)^2*5[/tex][tex]500\pi[/tex][tex]1570.8~m^3[/tex]-------------------------
hope it helps..
have a great day!!
Answer:
I believe it would be 1570.
Step-by-step explanation:
The formula to find the volume of a cylinder is:
V = pi • r² • h
The diameter is usually 2x the radius:
20m ÷ 2 = 10
The radius would be 10m.
3.14 • 10² • 5 = 1570 cubic m

Last month Maria hiked a total of 90 miles on two trails: a 5-mile mountain trail and a 10-mile canal trail. Let x represent the number of times Maria hiked the mountain trail, and let y represent the number of times Maria hiked the canal trail.
Which equation can be used to find the number of times Maria hiked each trail?
Answer:
5x+10y=90
Step-by-step explanation:
The equation that can be used to find the number of times Maria hiked each trail is 5x + 10y = 90.
How to depict the equation?From the information, Maria hiked a total of 90 miles on two trails: a 5-mile mountain trail and a 10-mile canal trail.
x represent the number of times Maria hiked the mountain trail.
y represent the number of times Maria hiked the canal trail.
The equation will be:
= (5 × x) + (10 × y) = 90
= 5x + 10y = 90
The equation is 5x + 10y = 90.

How many times would the cricket mostly likely chirp per minute if the temperature outside were 76^{\circ} ∘ F?
Answer:
834 chirps
Step-by-step explanation:
Given the data:
Chirps in 1 min Temperature (°F)
781 74
1039 85.9
1156 87.2
1218 87.8
1131 91.4
888 75.5
Using technology, the regression model obtained will be in the form :
y = bx + c
b = slope ; c = intercept
y = temperature ; x = chirps per minute
The regression model is :
ŷ= 43.28 + 0.0390x
If outside temperature, y = 76 ; x will be ;
76 = 43.28 + 0.0390x
76 - 43.28 = 0.0390x
32.72 = 0.0390x
x = 32.72 / 0.0390
x = 838.97435

Find m∠ABD and m∠CBD given m∠ABC = 111∘.
Answer:
m∠ABD = 88º
m∠CBD = 23º
Step-by-step explanation:
(-10x + 58) + (6x + 41) = 111
Combine like terms
-4x + 99 = 111
Subtract 99 from both sides
-4x = 12
Divide both sides by -4
x = -3
------------------------
m∠ABD = -10x + 58
m∠ABD = -10(-3) + 58
m∠ABD = = 30 + 58
m∠ABD = 88º
m∠CBD = 6x + 41
m∠CBD = 6(-3) + 41
m∠CBD = -18 + 41
m∠CBD = 23º
Answer:
88, 23
Step-by-step explanation:
<ABD + <DBC = <ABC
(-10x + 58) + (6x + 41) = 111
-10x + 58 + 6x + 41 = 111
99 - 4x = 111
-4x = 111-99
-4x = 12
x = 12/-4
x = -3
m∠ABD = -10x + 58
m∠ABD = -10(-3) + 58
m∠ABD = = 30 + 58
m∠ABD = 88º
<DBC = 6x + 41 = 6*-3 + 41 = -18 + 41 = 23

$3.15
Method 2:
1.40/4 = x/9
12.6 = 4x (cross multiply 9 and 1.4 and cross multiply 4 and x)
x = 12.6 / 4

=) Asif deposits $650 into a bank paying a simple interest. He leaves the money there
for 5 years. At the end of the 5 years, the amount in the bank is $763.75.
Calculate the percentage rate of interest the bank paid per year.
Answer:
interest he got per year is 22.75
Step-by-step explanation:
deposited money = 650
after 5 years = 763.75
interest he got = 763.75 - 650
= 113.75
interest he got each year = 113.75 / 5
= 22.75
WILL GIVE BRAINLIEST: What is the local minimum value of the function g(x)=x^4-5x^2+4? (Round answer to the nearest hundredth)
Answer:
Step-by-step explanation:
you can find where the first derivative is 0 to find the critical points
g'(x) = ( x^4 -5x^2 +4)' = 4x³-10x
g'(x) =0, make y =0 to find find where g'(x) is 0
4x³-10x =0 , factor 2x
2x(2x²-5)= 0 , each factor must be 0
2x= 0, so x= 0
2x²-5 =0, so x = ±√5/2
we now have 3 critical points -√5/2, 0, and √5/2
make intervals (-∞, -√5/2), (-√5/2, 0) , (0, √5/2) and (√5/2, +∞)
pick a point to test on each interval: -2, -1, 1 and 2 for example, and
calculate g'(x) = 4x³-10x at those points
for x= -2 we have 4(-2)³-10(-2) = -12 , negative number, decrease
for x= -1 we have 4(-1)³-10(-1) =6, positive number, increase
for x= 1 we have 4(1)³-10(1) = -6, negative number, decrease
for x= 2 we have 4(2)³-10(2) = 12, positive number, increase
we went from a decrease to an increase on intervals (-∞, -√5/2), (-√5/2, 0) so x= - √5/2 ≈ -1.58 is a minimum
we went from a decrease to an increase on intervals (0, √5/2), (√5/2, +∞) so
x= √5/2 ≈ 1.58 is a minimum as well
