The volume of a cone is represented by the formula V = 1 T?n. If the volume of a cone is 30rt and the height is 2.5, what is the radius of the cone?
Answer:
radius is 3.38cm
Step-by-step explanation:
Note: the volume of a cone is given as
[tex]V= 1/3 \pi r^2 h[/tex]
Step one:
Given Information
volume= 30cm^3
height= 2.5cm
Required
The radius of the cone
Step two:
substituting our data into the expression for the volume of a cone we can then solve for the radius r
[tex]30=1/3 *3.142*r^2 * 2.5\\\\30=1/3*7.855r^2\\\\30=2.62r^2\\\\[/tex]
divide both sides by 2.62
[tex]30/2.62= r^2\\\\11.45= r^2\\\\r=\sqrt{11.45} \\\\r=3.38cm[/tex]

Two cards are drawn at random from a standard deck of cards. What is the probability of not
drawing a 10 or a Queen? Round the answer to the nearest hundredth of a percent.
Answer:
0.85
Step-by-step explanation:
A standard deck of cards has 52 cards. There are 4 10s and 4 Queens in the deck. There 8 cards that are 10s or Queens.
52 - 8 = 44
There are 44 out of 52 cards that are not 10s or Queens.
p(not 10 or Queen) = 44/52 = 0.85
Answer: 0.85

Chelsea wants to join a fitness club. The fitness club charges and initial membership fee of $30 and a monthly fee of $10.50. She has $114 to spend on a membership at the fitness club. Right and solve an equation to find the number of months Chelsea can be a member of the fitness club
Answer:
She can be a member for 8 months
Step-by-step explanation:
Let x be the number of months
30 + 10.5(x) = 114
30 + 10.5x = 114
10.5x = 114-30
10.5x = 84
x = 84/10.5
x = 8 mints

7. Determine the value of x for which ris if
m_1 = 80 - X; and
• m22 90 - 2x.
The given is that r║s while the angles are known.
m∠1 = 80 - x
m∠2 = 90 - 2x
m∠1 = m∠2 because of corresponding angles theorem.
So,
m∠1 = m∠2
80 - x = 90 - 2x
- x = 90 - 80 - 2x
- x = 10 - 2x
- x + 2x = 10
x = 10
The value of x is 10

Step-by-step explanation:
If gymnast can do 4 back handsprings in 36 seconds , then for 1 backspring the gymnast took 36/4 = 9 seconds.
If the gymnast took 9 seconds for 1 back handsprings, Time taken by the gymnast to do 7 backsprings = 9×7 = 63 seconds
1. What is the slope of the line shown?
Answer:The slope equals the rise divided by the run: . You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope.

Answer:
Gradient of KL = 2
Step-by-step explanation:
From the diagram, we are to calculate the gradient of KL. Gradient is salso known as the slope of the line.
Gradient of KL = ΔOK/ΔOL
Given
OK = 2OL
Substitute into the formula
From the diagram, ΔOL = -5
ΔOK = 2ΔOL
ΔOK = 2(-5)
ΔOK = -10
Hence;
Gradient = -10/-5
Gradient of KL = 2

What is the solution of the system of equations? Y=x-4 and y=-3x
Answer:
(-7,-3)
Step-by-step explanation:
step one) solve one equation for x.
y=-3x
-3x/-3=y/-3
x=(-y/3)
step two) plug in x for the other original problem.
y=x-4
y=(-y/3)-4
step three) solve for y.
y=(-y/3)-4
y+4=(-y/3)-4+4
3*(y+4)=(-y/3)*3
3y+12=-y
(3y+12)-3y=-y-3y
12/-4=-4y/-4
y=-3
step four) plug in -3 for y and solve for x.
y=x-4
-3=x+4
-3-4=x+4-4
-7=x

What transformation was not done to the linear parent function, f(x) = x, to get the function g(x) = - 5(x - 3) - 8 ? A. Reflection over the x-axis B. Shift down 8 units C. Horizontal stretch by a factor of 5 D. Shift right 3 units
Answer:
A. Reflection over the x-axis.
Step-by-step explanation:
Now, we present how to transform [tex]f(x) = x[/tex] into [tex]g(x) = -5\cdot (x-3)-8[/tex] below:
1) [tex]f(x) = x[/tex] Given.
2) [tex]f(x-3) = x - 3[/tex] Horizontal shift to the right.
3) [tex]-5\cdot [f(x-3)] = -5\cdot (x-3)[/tex] Vertical scale factor.
4) [tex]-5\cdot f(x-3)-8 = -5\cdot (x-3)-8[/tex] Vertical shift downwards.
5) [tex]g(x) = -5\cdot (x-3)-8[/tex] Definition/Result
In consequence, the only transformation which was not done to the linear parent function was a reflection over the x-axis. The correct answer is A.

Use quotient rule!See attached image for solution30 men repair a road in 56 days by working 6 hours daily. in how many days 45 men will repair same road by working 7 hours daily?
Answer:
Case1:
Men : 30
Work : 1
Time (day×hr): 56×6 = 336 hr.
Case2:
Men : let it be m men.
Work: 1
Time: 45×7 = 315 hr.
Work being constant in both cases, men and time are in inverse proportion i.e, more men take less time.
Product of men and time is constant in both cases.
Therefore, 30×336=m×315
Or, 30×336/315 = m
Or, m = 32.
Hence, required number of men is 32.

The acceleration of an object due to gravity is 24 feet per second squared. What is the acceleration due to gravity in inches per second squared?
288 inches per second squared
B
2 inches per second squared
С
72 inches per second squared
D
3,456 inches per second squared
The acceleration due to gravity in inches per second squared is
288 inches / seconds²
Option A is the correct answer.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 hour = 60 minutes
1 minute = 60 seconds
1 km = 1000 m
1 feet = 12 inches
We have,
The acceleration of an object due to gravity:
= 24 feet / seconds²
Now,
1 feet = 12 inches
24 feet = 288 inches
So,
24 feet / seconds²
= 288 inches / seconds²
Thus,
The acceleration of an object due to gravity is 288 inches / seconds².

Point Q is the midpoint of AB. Q has coordinates of (-2, 4) and A has coordinates of (4,6). What are the coordinates of point B?
Step-by-step explanation:
Let (x, y) be the coordinates of point B.
(4, 6) => (-2, 4) => (x, y)
We have 2(-2) = 4 + x and 2(4) = 6 + y.
Solving these, we get x = -8 and y = 2.
Hence the coordinates of point B is (-8, 2).
Point Q is the midpoint of AB. Q has coordinates of (-2, 4) and A has coordinates of (4,6). Hence the coordinates of point B will be (-8, 2).
What are the coordinates of the midpoint of the line segment AB?Suppose we've two endpoints of a line segment as:
A (p,q), and B (m,n)
Then let the midpoint be M(x,y) on that line segment.
Then, its coordinates are:
[tex]x = \dfrac{p+m}{2}[/tex]
and
[tex]y = \dfrac{q+n}{2}[/tex]
Let (x, y) be the coordinates of point B.
Q has coordinates of (-2, 4).
A has coordinates of (4,6).
A (p,q) = (4, 6)
M(x,y)= (-2, 4)
B = (x, y)
We have
2(-2) = 4 + x
2(4) = 6 + y.
Solving these, we get
x = -8 and y = 2.
Hence the coordinates of point B will be (-8, 2).
