Answer:

Divide by -2

Step-by-step explanation:

Since we need to isolate h, we need to do the opposite operation that -2 is doing to h. In this case, -2 is being multiplied by h, and the opposite operation to multiplication is division.

This means that we need to divide both sides by -2.

Consider the formula for surface area, SA = (p • h) + 2B. The perimeter is

The aquarium has 6 fewer yellow fish than green fish. 40 percent of the fish are yellow. How many green fish are in the aquarium? Show your work.

Please explain using simple words : D

Answers

Answer: 18 green fish

Step-by-step explanation:

       We will write what we know using mathematical equations. Let y be yellow fish and g be green fish. Please note that a percent, 40%, divided by 100 becomes a decimal, 0.4.

-> The aquarium has 6 fewer yellow fish than green fish.

   y = g - 6

-> 40 percent of the fish are yellow.

   y = 0.4 * (y + g)

[tex]--------------------------------------------[/tex]

       Now, we can solve them as a regular system of equations. First, we will find the number of green fish. There are 18, as shown by the work.

   y = 0.4 * (y + g)

   (g - 6) = 0.4 * ((g - 6) + g)

   g - 6 = 0.4 * (2g - 6)

   g - 6 = 0.8g - 2.4

   g = 0.8g + 3.6

   0.2g = 3.6

   g = 18

        There are 18 green fish in the aquarium.

Lou's shoe was 9.178 inches long, Helen's shoe was 7.093 inches long, Jay's shoe was 10.554 inches long and Craig's shoe was 4.112 longer than Helen's. How long will the row of shoes be if someone placed them in a line from end to end?

Answers

Answer:

38.03 in

Step-by-step explanation:

Step 1: Calculate Craig's shoe length.

It's 4.112 in longer than Helen's shoe, which is 7.093 in. So, we simply add those two numbers to get 11.205.

Step 2: Add up all of the numbers

Now that we have everyone's shoe lengths, we just add them all up to get 38.03 in.

The number of pages that Ana, Hillary, Roger, and Juan can read in a day is shown below:

Ana read 15% of her 46-page book.
Hillary read 11% of her 72-page book.
Roger read 12% of his 68-page book.
Juan read 14% of his 69-page book.

Who can read the greatest number of pages in a day?

Ana
Hillary
Roger
Juan

Answers

Ana: 0.15(46) = 6.9 pages per day

Hillary: 0.11(72) = 7.92 pages per day

Roger: 0.12(68) = 8.16 pages per day

Juan: 0.14 (69) = 9.66 pages per day

Ans•

Answer: Juan

Step-by-step explanation:

Step 1: Find how many pages each person read.

ANA

15% of her 46 page book

Whenever you have something% OF something, you just turn the 'of' into a multiplication sign.

15% x 46

Next, turn 15% into a decimal. There are 3 ways to do this. (1. put a decimal point right before the number (2. move it 2 places to the right, (3. just divide by 100. Either way, 15% becomes 0.15

0.15x46= 6.9

Ana can read 6.9 pages in a day.

HILARY

11% of a 72 page book

Same method I used for Ana. turn "of" into multiplication, convert the percentage to a fraction by moving the point 2 places left, and multiply.

**11 is the same as 11.0, which becomes 0.11.**

11% x 72

0.11x72= 7.92

Hilary can read 7.92 pages in a day.

ROGER

12% of 68 pages

of becomes multiply

12% becomes 0.12 because 12 is the same as 12.0, and you move 12 2 places to the left.

now we have 0.12x68= 8.16

JUAN

14% of 69 pages

of becomes multiply, 14 is the same as 14.0, move it 2 places to the left and it becomes 0.14. boom.

0.14x69= 9.66

Juan can read 9.66 pages in a day.

Step 2: Line up all of the numbers and find the biggest one.

Ana: 6.9 pages per day

Hilary: 7.92 pages per day

Roger: 8.16 pages per day

Juan: 9.66 pages per day

9.66 is the greatest number.

Juan can read the most pages per day

In a music competition, a participant has to score a total of at least 40 points in the first four rounds combined to move on to the fifth and final round. Glenn scored 4 points in the first round. He then went on to score additional points in the second, third, and fourth rounds. In each of those rounds, his score was identical. Which inequality best shows the number of points, p, that Glenn scored in each of the second, third, and fourth rounds if he earned a place in the finals?

a 4 + 3p ≤ 40
b 4 + 3p ≥ 40
c 4p + 3 ≥ 40
d 4p + 3 ≤ 40

Answers

Answer:

b 4 + 3p ≥ 40

Step-by-step explanation:

he needs more than 40 points, so we need to pick and answer with a greater than or equal to sign that faces the side with Glenn's points. This leaves b or c for our answers. Glenn played 3 different rounds in which he scored a value represented by the variable p. Additionally, he scored a value of 4 points is given. Therefore, because he scored p in 3 different rounds, p is multiplied by 3 to make 3p. So, 4+3p≥ 40 (answer b) is correct

Answer:

b 4 + 3p ≥ 40

Answer: There are 24 frames of animation in 1 second of anime.

Step-by-step explanation:

There are 60 seconds in 1 minute, and 60 minutes in 1 hour. 60×60=3600, so there are 3600 seconds in 1 hour.

Since 3600 seconds and 1 hour is the same, there are 86400 frames of animation in 3600 seconds of anime. To find out how many frames are in one second of anime, divide 86400 by 3600.

86400 ÷ 3600 = 24

Cube A volume = 5832 in³

For Cube B dimension in inches:

1.2 feet = 14.4 in1 feet = 12 in1 feet = 12 in

So Volume of Cube B:

L × B × H = 14.4 × 12 × 12 = 2073.6 in³

Can someone help me solve this? Pls and ty!

Answers

Answer:

H. 95°

Step-by-step explanation:

m∠BGC is 10° smaller than m∠CGD, which means that m∠BGC is x° - 10°

m∠DGE is 25° more than m∠EGF, which means that m∠DGE is x° + 25°

The sum of all angles in a placement like this will always equal 360°

So we put all the measures of all angles on one side of thee equation and set it equal to 360*

x° + x° - 10° + 2x° + 25° + 2x° + 3x° + 30° = 360°

After combining like terms we get 9x° + 45° = 360°

After some algebra we get x = 35°

Now at the start we said that m∠DGE is x + 25°

Plug in 35° for x and we get 35° + 25°

The final answer is m∠DGE = 95°
