need help with my hw make H the subject of the formula x = 5h + 8
Answer:
h = (x - 8)/5
Step-by-step explanation:
Step 1: Write out expression
x = 5h + 8
Step 2: Isolate variable h (Subtract 8 on both sides)
x - 8 = 5h
Step 3: Isolate h (Divide both sides by 5)
(x - 8)/5 = h
Step 4: Rewrite
h = (x - 8)/5

Find the volume of a cylinder with a diameter of 8 inches and a height that is three times the radius. Use 3.14 for pi and round your answer to the nearest hundredth. (Hint:
You may only enter numerals, decimal points, and negative signs in the answer blank)
Answer:
Step-by-step explanation:
Start by finding the radius
d = 8
r = d/2
r = 8/2
r = 4
Next find the height
the height = 3 times the radius
the height = 3 * 4
The height = 12
Volume = pi * r*r * h
pi = 3.14
r = 4
h = 12
V = 3.14 * 4 * 4 * 12
V = 602.88

Answer:
x² + (y - 2)² = 144
Step-by-step explanation:
Standard equation of a circle is given by,
(x - h)² + (y - k)² = r²
Where (h, k) is the center of the circle and 'r' is the radius.
If the center of the circle is (0, -2) and radius 'r' = 12 units
Equation of the circle will be,
(x - 0)² + (y + 2)² = (12)²
x² + (y - 2)² = 144
Therefore, equation of the circle will be,
x² + (y - 2)² = 144
If 3x + 6y = 7z, find x + 2y in terms of z.

Recall the difference between an equation and an inequality. Then, identify whether these mathematical statements represent an equation or an inequality.
Answer:
If it were an equation, it would be in the form ax+by+c=0, however if it were an inequality, instead of the equal sign it would be an inequality sign like greater than or less than.
Step-by-step explanation:
Solve the equation for all values of x in simplest form: (x-9)^2 = 15
[tex](x-9)^2=15\\x-9=\sqrt{15} \vee x-9=-\sqrt{15}\\x=9+\sqrt{15} \vee x=9-\sqrt{15}[/tex]

PLEASE HELP Ruri is a 30-year-old math teacher. She has been informed that she is the winner of a grand prize for the lottery. She can choose either a one-time payment of $20 million or $5000 per week for the rest of her life. Which choice would most likely result in the greatest amount of winnings for Ruri? Explain your reasoning.
Answer:
$5,000 per week
Step-by-step explanation:
Ruri is a 30 year old female.
there are about 4 weeks per month
there are about 52 weeks per year
52*5000 = 260,000
She would get 260,000 per year and lets see how much she would have at 40.
260,000*10
at 40 she would have 2,600,000
2,600,000*10
at 50 she would have 26,000,000
at 50 she already has earned more money that the $20 million.
She should go with the $5000 per week if she would like more money.
A rhombus that is a rectangle is called
square ?
although this statement doesn't make any sense.
Answer:
Square!
Step-by-step explanation:
A rectangle is a parallelogram with all its interior angles being 90 degrees. A rhombus is a parallelogram with all its sides equal. This means that for a rectangle to be a rhombus, its sides must be equal. When this is satisfied, we have a square.

Consider the following system of equations: y=2x−2 6x+3y=2 The graph of these equations consists of two lines that: 1. intersect at more than one point. 2. intersect in an infinite number of points. 3. intersect at exactly one point. 4. do not intersect.
Answer:
3. Intersect at exactly one point. ( (2/3), (-2/3) )
Step-by-step explanation:
To make the comparison of these lines easier, let's rewrite the 2nd equation into slope-intercept form, as the 1st equation is in slope-intercept form.
[1] y = 2x - 2
---------------------
[2] 6x + 3y = 2 ==> 3y = 2 - 6x ==> y = -2x + (2/3)
[2] y = -2x + (2/3)
So now that we have both equations in slope-intercept form, we can see that the two equations are both linear, have different slopes, and have different y-intercepts.
Since these equations have both different slopes and different y-intercepts, we know that the lines will cross at least one point. We can confirm that the lines only cross at a single point using the fact that both equations are linear, meaning there will only be one point of crossing. To find that point, we can simply set the equations equal to each other.
y = 2x - 2
y = -2x + (2/3)
2x - 2 = -2x + (2/3)
4x = (8/3)
x = (8/12) = (2/3)
And plug this x value back into one of the equations:
y = 2x - 2
y = 2(2/3) - 2
y = (4/3) - (6/3)
y = (-2/3)
Thus these lines only cross at the point ( (2/3), (-2/3) ).
Cheers.

gayle started with 30 pairs of shoes and donated X pairs. Her sister Bonnie started with 22 pairs of shoes and donated half as many pairs as Gayle did. How many pairs of shoes did Gayle donate if they had the same number of shoes remaining
Answer:
16 pair of shoes
Step-by-step explanation:
If Gayle donated x pairs, it means he is left with 30 - x pair of shoes.
Bonnie donated half as many as Gayle as donated.
We know Gayle donated x pairs, so Bonnie must have donated x/2.
Bonnie is left with 22 - (x/2) pairs after donation.
The question says, after donation they have the same number of pair of shoes.
It means, 30 - x = 22-(x/2),
If you will manipulate this equation and make x the subject,
you will get x=16.
I hope it helps.
Gayle donated 16 shoes
Number of shoes Gayle has after the equation can be represented with this equation : 30 - x
Where x = number of shoes she donated
Number of shoes Bonnie donated = 0.5x
Number of shoes Bonnie has after the equation can be represented with this equation : 22 - 0.5x
If Bonnie and Gayle ended with the same amount of shoes after the donation, this can be represented as:
30 - x = 22 - 0.5x
Combine similar terms
30 - 22 = x - 0.5x
8 = 0.5x
Divide both sides of the equation by 0.5
x = 16

Micha is playing a game with five cards numbered 1 through 5. He will place the cards in a bag and draw one card at random three times, replacing the card each time. To win a prize, he must draw the number 5 all three times. What is the probability he will draw the number 5 all three times?
Answer: 0.008
Step-by-step explanation:
We have 3 experiments.
Each experiment is exactly the same: "Drawing the card with the number 5, out of a bag with five cards".
in a random selection all the cards have exactly the same probability of being drawn, so the probability of drawing the 5, is equal to the quotient between the number of cards with the 5 (only one) and the total number of cards in the bag (5) then the probability is:
p = 1/5.
And we want this event to happen 3 consecutive times, then the total probability is equal to the product of the probabilities for each event:
P = (1/5)*(1/5)*(1/5) = 1/125 = 0.008

The product of the numbers in scientific notation is 4.16 × 10⁻⁵
Given data:
To calculate the product, we multiply the coefficients and add the exponents of 10:
(5.2 × 10⁻²) × (8.0 × 10⁻⁴) = 5.2 × 8.0 × 10⁻² × 10⁻⁴
Multiplying the coefficients:
5.2 × 8.0 = 41.6
Adding the exponents of 10:
10⁻²× 10⁻⁴ = 10^(-2 - 4) = 10⁻⁶
Putting it all together:
(5.2 × 10⁻²) × (8.0 × 10⁻⁴) = 41.6 × 10⁻⁶
Hence, the final answer in scientific notation is: 4.16 × 10⁻⁵

Write an expression in simplified form for the area of each rectangle. Width: 11 Length: 3x+2
Answer:
33x+22
Step-by-step explanation:
The area of a rectangle is
A = l*w where l is the length and w is the width
A = 11(3x+2)
Distribute
= 33x+22
Area of rectangle = Length * Width
Length is 3x+2Width is 11⇛Area = 11(3x+2)
⇛Area = 33x + 22
George goes to the supermarket to buy some canned tomatoes to make salsa for a party. The cans are on sale for $0.95 each. He has $4.75. Let x represent the number of cans that he can buy. Which equation models this situation?
Answer:
see below
Step-by-step explanation:
Take the price of each can and multiply by the cost of the cans
.95x
This must be less than or equal to 4.75
.95x ≤ 4.75
They may choose to use an equals sign, since they asked for an equation
.95x = 4.75
Answer: 0.95x = 4.75
Step-by-step explanation:
Since we do not know how much George can buy, we will put x as 0.95x
If you solve 0.95x=4.75 by dividing 0.95 on both sides you will get the number of cans he can buy which is 5.

To find the surface area of the pyramid, find the area of each surface and add them together.
formula for area of a triangle = 1/2(b·h)
1. There are three triangles with a base of 9 and a height of 9
1/2(9·9) = 40.5
Multiply by the three triangles
40.5 · 3 = 121.5
2. There is one triangle with a base of 9 and a height of 7.8
1/2(9·7.8) = 35.1
