The following cone has a height of 4 inches and a volume of 12π. What is the radius of the cone? Enter your answer as the correct value, rounded to the nearest tenth if necessary.
Answer:
R= 1.69
Step-by-step explanation:
For this, you just have to remember that the volume of a cone is 1/3hπr² (1/3 times pi times the radius squared). Our volume is 12π, so we plug in 12π into our formula, as well as our height of 4 inches, to solve for the radius, like so:
12π=(1/3)(4)πr²
Now we just do the rest of the math.
12π=(1/3)(4)πr²
12=(1/3)(4)r² (divide both sides by π)
3=1/3r² (divide both sides by 4)
9=r² (divide both sides by 1/3)
3=r (take the square root of both sides).
Therefore, the radius of the cone is 3.

ABCD is a rhombus. The diagonals intersect at point E. If angle CDB= 6x and angle ACD= 2x+10, find x.
Answer:
x = [tex]10^{o}[/tex]
Step-by-step explanation:
The diagonals of a rhombus are perpendicular to each other, thus the angle at point E is [tex]90^{o}[/tex]. So that ΔCED is a right triangle, and that;
<CDB = <CDE
<ACD = <ECD
<CDE + <ACD + <CED = [tex]180^{o}[/tex] (sum of angles in a triangle)
6x + (2x + 10) + [tex]90^{o}[/tex] = [tex]180^{o}[/tex]
8x + 100 = [tex]180^{o}[/tex]
8x = [tex]180^{o}[/tex] - 100
8x = 80
x = [tex]\frac{80}{8}[/tex]
= [tex]10^{o}[/tex]
Thus, the value of x is [tex]10^{o}[/tex].
Find the area of a circle with radius 8yd.
Use the value 3.14 and do not round your answer.
Be sure to include the correct unit.
Answer:
Area of a circle = 200.96 yd²
Step-by-step explanation:
Area of a circle = πr²
Radius, r = 8 yd
π = 3.14
Area of a circle = πr²
= 3.14 * (8 yd)²
= 3.14 * 64
= 200.96 yd²
Area of a circle = 200.96 yd²

Topic: Math
Solve all the questions
Answer:
1. x= 9
2. x= −2
3. 51 inches
4. $213.11 each month
Step-by-step explanation:
1. Simplify both sides of the equation.
x + 7 + 7x= 25 + 6x
Combine Like Terms
(x + 7x) + (7)=6x + 25
8x + 7= 6x + 25
8x + 7= 6x + 25
Subtract 6x from both sides.
8x + 7 − 6x= 6x + 25 − 6x
2x + 7= 25
Subtract 7 from both sides.
2x + 7 − 7= 25 − 7
2x= 18
Divide both sides by 2.
2x/2= 18/2
2. Subtract 5x from both sides.
x − 5x= 5x + 8 − 5x
−4x= 8
Divide both sides by -4.
−4x/−4= 8/−4
3. First find the perimeter of the trapezoid
4 + 3 + 4 + 8= 19
A square has all equal sides
8 * 4= 32
Add them together
19 + 32 = 51 inches
4. Subtract the amount she put for finance from the total

$213.11 each month

Answer:
50
hope this helps
have a good day :)
Step-by-step explanation:
Answer:
D. 50
Step-by-step explanation:
∠CGF and ∠AFG add up 180° because they are same side interior angles. We can write an equation to model the situation:
m∠CGF + m∠AFG = 180°
And, we can substitute:
3x - 20 + x = 180
4x - 20 = 180
4x = 200
x = 50
The measure of L in triangle LMN is 36°. The measure of M is 75°. What is the measure of N? PLEASE HELP
A.
111°
B.
39°
C.
69°
D.
249°
Answer:
C. m∠N = 69°
Step-by-step explanation:
The sum of the measures of the angles of a triangle is 180.
m∠L + m∠M + m∠N = 180
36 + 75 + m∠N = 180
111 + m∠N = 180
m∠N = 69°

DOES ANYONE KNOW HOW TO DO THESE???
Answer:
Step-by-step explanation:
7. The horizontal translation is 3 units to the right, this is determined by the value that is being added or subtracted to x directly. In this case, x is being subtracted by 3 meaning that it is translated 3 units to the right.
8. It is being translated 2 units up. This is determined by the number that is added to the quadratic equation. In this case, it is increased by 2 which means an upward translation. If it was being subtracted it would be a downward translation.
9. Yes, when a quadratic equation has a negative sign outside of it which changes its values it means that it is being reflected.

A study with a sample that is very different from the population is biased
What is Population Density?The population density, or the number of people divided by the area's size, is determined by the number of people who reside there. Numerous creatures' distribution, growth, and migration can all be explained by population density.
Population density = number of people / the area they occupy
Given data ,
A study with a sample that is very different from the population is J. biased.
In statistical terms, bias refers to any systematic error or deviation from the true value that can occur in a study. When a study is biased, the results may not be representative of the population and may not be generalized other settings.
Results from a research may be skewed if the sample chosen is considerably different from the population. Both experimental and observational research may experience this. As a result, alternatives F and G do not offer sufficient details to assess the study's objectivity.

What is the measure of ∠A, the exterior angle of the triangle shown below?
Answer:
88
Step-by-step explanation:
Each triangle has a sum of 180 degrees. So we find the missing angle with this rule.
180-38-50.
The angle is 92 degrees.
Now to find the angle of A, each angle adds up to 180 on a line. so 180-92. So you get 88
Answer:
Step-by-step explanation:
38+50=angle A(the sum of two interior opposite angle is equal to the external angle formed)
88=angle A

Andre and Eric are each saving money. Andre starts with `\$100` in his savings account and adds `\$5` per week. Eric starts with`\$10` in his savings account and adds `\$20`each week.
This question is incomplete
Complete Question
Andre and Elena are each saving money. Andre starts with $100 in his savings account and adds $5 per week. Elena starts with $10 in her savings account and adds $20 each week. After four weeks, who has more money in their savings account?
Answer:
Andre
Step-by-step explanation:
Andre and Elena are each saving money.
For Andre
Number of weeks = 4
Andre starts with $100 in his savings account and adds $5 per week.
Hence, the total number of money Andre has after 4 weeks is
$100 + $5 × 4
$100 + $20
$120
For Elena
Elena starts with $10 in her savings account and adds $20 each week.
Hence, the total number of money Elena has after 4 weeks is
$10 + $20× 4
$10 + $80
$90
Therefore, after four weeks, the person who has more money in their savings account is Andre.

Leila is at a charity fundraiser and has a chance of receiving a gift 6/17 . The odds in favor of receiving a gift are . Find the probability of Leila receiving a gift.
Answer:
6 / 23
Step-by-step explanation:
The question is not correct, the correct question is:
Leila is at a charity fundraiser and has a chance of receiving a gift. The odds in favor of receiving a gift are 6:17. Find the probability of Leila receiving a gift.
Solution:
Odds provide a measure of the likelihood of a particular outcome occurring. Odds is the ratio of the number of events that produce that outcome to the number that do not.
The probability of an event occurring is the ratio of number of favorable outcomes to the total number of outcomes possible.
Given that the odds in favor of receiving a gift are 6:17. Therefore:
number of favorable outcome = 6, number of unfavorable outcome = 17
Total number of possible outcomes = 6 + 17 = 23
The probability of Leila receiving a gift = number of favorable outcome / Total number of possible outcomes = 6 / 23
The probability of Leila receiving a gift = 6 / 23
