Answer:
3017.54
Step-by-step explanation:
Volume for area of circle is A = Pie ( Or in this case 3.14 ) * radius ^ 2
Plug in the numbers 3.14 * 31 ^2
31 is half the diameter or the radius
Answer = 3017.54
Evaluate 10x2y–2 for x = –1 and y = –2.
A: 5/8
B: 40
C:2 1/2
D:10(2)^0
Step-by-step explanation:
what you typed in here must be wrong or incomplete.
what you typed is (with explicit multiplication symbols to make it clear)
10×x×2×y - 2
for x=-1 and y=-2
that shows then
10×-1 × 2×-2 - 2 = -10 × -4 - 2 = 40 - 2 = 38
but 38 is not in the answer options.
so, there must be something wrong with your problem description.

In a basketball contest, Elizabeth made
9 out of 25 free throw attempts. Alex
made 8 out of 20 free throw attempts.
Janie said that Elizabeth had a better
free-throw record because she made
more free throws than Alex.

» A. Critique Reasoning
Do you agree with Janie's reasoning? Explain.
Answer:
No, Alex had the better free throw percentage
Step-by-step explanation:
If you turn these data sets into completion percentage, (which is when you make a shot), Alex has a free throw % of 40, while Elizabeth's free throw % is only 36

If tan0 = 1 then, find the values of
sec 0 + cosec
Answer:
We know that:
Tan(x) = sin(x)/cos(x)
We know that:
Tan(θ) = 1 = sin(θ)/cos(θ)
we can rewrite this as:
sin(θ)/cos(θ) = 1
sin(θ) = cos(θ)
If you know the table of notable angles, the angle such that this is true is θ = 45°
sin(45°) = 1/√2 = cos(45°)
Now we want to find the value of:
sec(θ) + cosec(θ)
Where:
sec(θ) = 1/cos(θ)
cosec(θ) = 1/sin(θ)
And we already know the values of the sine and cosine function, then:
sec(45°) + cosec(45°) = 1/cos(45°) + 1/sin(45°) = 2*(1/( 1/√2)) = 2*√2
Then, given that:
Tan(θ) = 1
We can conclude that:
sec(θ) + cosec(θ) = 2*√2

The distribution of household incomes in a small town is strongly skewed to the right. The mean income is $42,000 and the standard deviation is $24,000. The Ames family’s household income is $60,000. The z-score for the Ames family’s income is
Answer:
0.75
Step-by-step explanation:
Given :
mean = 42000
Standard deviation = 24000
score, x = 60000
The Zscore :
Zscore = (score - mean) / standard deviation
(60000 - 42000) / 24000
18000 / 24000
= 0.75
Find the 5th term in the expansion of (a + b)º in simplest form.
Answer:
[tex]5^{th} term = 126a^5b^4[/tex]
Step-by-step explanation:
[tex]\left(a+b\right)^n=\sum _{i=0}^n\binom{n}{i}a^{\left(n-i\right)}b^i\\\\(a + b)^9 =\sum _{i=0}^9\binom{9}{i}a^{\left(9-i\right)}b^i\\\\[/tex]

John deposits Rs 25 000 in a bank which pays simple interest at the rate of 9% per year. after how many years will he earn an interest of Rs 6750?
I = 6750
P= 25000
r = 9% = 0.09
t=?
I= prt
6750 = 25000×0.09× t
t = 6750/25000"0.09 = 3
Answer - 3 years.

You deposit $50,000 in a savings account. After 10 years, your balance is $65,000. What is your interest rate?
Answer:
r = .03 or 3%
Step-by-step explanation:
Interest = Principal x Rate x Time
15000 = 50000(10)r
15000 = 500000r
r = 15/500
r = .03 or 3%

There is a square field of side 45m. There is a well in this field of area of 5 sq. Metre. In the remaining part, we plant coconut trees at the rate of one plant per sq.Metre . How many trees can be planted in the field? If the cost of planting one tree is Rs. 75. What is the total cost of planting the trees?
Answer:
Numbner of plant in field = 2,020
Cost of planting trees = R.s 151,500
Step-by-step explanation:
GIven:
Side of square field = 45 m
Area of well = 5 square meter
1 plant = 1 squre meter
Cost per tree = R.s 75
Find:
Numbner of plant in field
Cost of planting trees
Computtaion:
Area of planting trees = Area of filed - Area of well
Area of planting trees = [45 x 45] - 5
Area of planting trees = 2,025 - 5
Area of planting trees = 2,020 squre field
Numbner of plant in field = Area of planting trees / 1 squre meter
Numbner of plant in field = 2,020
Cost of planting trees = 75 x Numbner of plant in field
Cost of planting trees = 75 x 2,020
Cost of planting trees = R.s 151,500

find the radian measure of an angle of 110 degrees
Answer:
0.611 rad
Step-by-step explanation:
For the radian measure:
180° = π radians
180° : 110° = 11 / 18 ≈ 0.611
110° = 11π/18 rad ≈ 0.611 rad

here is the question:
The volume of this cylinder is approximately 12,468.94 cubic feet.
The radius is ___ feet.
Use ≈ 3.14.
image is also pasted
Answer:
radius = 19 ft
Step-by-step explanation:
volume of a cylinder: r²πh
12468.94 = r²π × 11
=> r² = 12468.94 ÷ 11π
=> r² = 361
=> r = 19
Answer:
r=19
Step-by-step explanation:
[tex]12468.94 = (3.14) {r}^{2} (11) \\ \frac{12468.94}{34.54} = \frac{34.54 {r}^{2} }{34.54} \\ \sqrt{361} = \sqrt{ {r}^{2} } \\ 19 = r[/tex]

Answer:

First of all, we can see that angle 1 is 132 degrees because they are the same angles/measurements. Therefore, angle 1 and angle 3 are also supplementary as they create a straight line, or 180 degree angle. As they are supplementary, angle 1 + angle 3 = 180. We know that angle 1 is 132, so we have 132 + angle 3 = 180, and angle 3 is 42 degrees.

Step-by-step explanation:
The angle \theta_1θ 1 theta, start subscript, 1, end subscript is located in Quadrant \text{I}Istart text, I, end text, and \sin(\theta_1)=\dfrac{17}{20}sin(θ 1 )= 20 17 sine, left parenthesis, theta, start subscript, 1, end subscript, right parenthesis, equals, start fraction, 17, divided by, 20, end fraction .
Answer:
[tex]\cos(\theta_1) = \frac{\sqrt{111}}{20}[/tex]
Step-by-step explanation:
Given
[tex]\sin(\theta_1) = \frac{17}{20}[/tex]
[tex]Quadrant = 1[/tex]
Required
[tex]\cos(\theta_1)[/tex]
We know that:
[tex]\sin^2(\theta_1) + \cos^2(\theta_1) = 1[/tex]
This implies that:
[tex](\frac{17}{20})^2 + \cos^2(\theta_1) = 1[/tex]
Collect like terms
[tex]\cos^2(\theta_1) = 1 -(\frac{17}{20})^2[/tex]
[tex]\cos^2(\theta_1) = 1 -\frac{289}{400}[/tex]
Take LCM and solve
[tex]\cos^2(\theta_1) = \frac{400 -289}{400}[/tex]
[tex]\cos^2(\theta_1) = \frac{111}{400}[/tex]
Take square roots
[tex]\cos(\theta_1) = \frac{\sqrt{111}}{\sqrt{400}}[/tex]
[tex]\cos(\theta_1) = \frac{\sqrt{111}}{20}[/tex]
