Hope it helps! :)

Susan's art class is 540 minutes long. Frank drinks 3 cups of milk a day. The cook needs 2 pints of vegetable broth for their recipe. The coral reef grew 9 meters taller.

To solve these measurement conversion problems, we'll work through each one step by step:

Susan's art class is 9 hours long. Since there are 60 minutes in an hour, her class is 9 hours × 60 minutes/hour = 540 minutes long.To convert Frank's milk consumption from pints to cups, we use the fact that 1 pint is equal to 2 cups. So, 1 ¹/₂ pints is the same as 1.5 × 2 cups, which equals 3 cups.When converting the 4 cups of vegetable broth to pints, we remember that 2 cups is equivalent to 1 pint. Therefore, 4 cups is equal to 2 pints.The coral reef grew by 9000 millimeters. To find this growth in meters, we use the conversion that 1000 millimeters is equal to 1 meter. Therefore, it grew by 9000 mm × (1 m / 1000 mm) = 9 meters.

I need help with this work sheet in algebra 2 I need some understanding can someone please help me?

Answers

When it says 7 more than a number equals 21, the "more than" is addition, a number is x (because it's the unknown number). So this one is x+7=21.

When it says 39 less than a number is 21. "Less than" means to subtract. The 39 is less than x, so it's x-39=21.

8 times a certain number increased by 1 is 65. Break it down, first 8 times a number, so it's 8*x or 8x. Then we add 1 to that, so it's 8x+1=65.

5 times some number decreased by 2 times the number is 42. Decreased by is subtraction. So it's 5x-2x=42.

When you look for the key words increased by (add), more than (add), multiplied by, times, less than (subtract), decreased by (subtract), is (equal sign), they will help determine what you need to do.

I hope this gives you a little more understanding. Good luck with it! :)

If a cube shaped box has a volume of 1331 cubic inches how tall is the box.

Answers

It is 0.5.97 as u know triangle equals to square so g5.0 is the equation for this and divide by square that is ur answer

Answer: Cube is 11 inches tall

Explanation:

Cube has all edges the same length . The volume of a cube is multiplying the length of any edge, height and width of the cube.

Volume of cube = length * width * height

We know that length = width = height = s

So, Volume of cube = s*s*s

= s³

In given question:

Volume of the cube = 1331 cu in.

s³ = 1331

take cube root both the side

s = ∛1331

s = ∛(11*11*11)

s = 11 inch

So, height of the cube = 11 inches

How do you do this simultaneous equation?

Answers

The y is the same for both equations. Equate them
-x - 5 = 2x + 4 Add x to both sides
- 5 = 3x + 4 Subtract 4 from both sides.
- 9 = 3x Divide by 3
x = -9 / 3
x = - 3

y = - x - 5
y = -(-3) - 5
y = - 2

So that point is where the two equations meet.

2(5x-4)=ax+b
Find a value for a and b so that the solution is
A. Has one solution
B. Has no solutions.
C. Infinite Solutions

Answers

A: One solution- a=11 b=5
B: Has no solution- a=10 b=5
C: Infinite solution- a=10 b=-8

Answer:

A. a = 0, b = 2

B. a = 10, b = 0

C. a = 10, b = -8

Step-by-step explanation:

2(5x-4)=ax+b

10x - 8 = ax + b

When a = 10, b = -8

This equation becomes true for all x. Hence infinite solutions.

When a = 10, b is not -8,

This equation has no solution.

One possible combination could be:

a = 10, b = 0

When a is not 10,

The two sides of the equation become two non parallel lines which will intersect at one point.

A combination could be:

a = 0, b = 2

Miguel is driving his motor boat across the river. The speed of the boat in Still water is 14 mi/h. The river flows directly south at 2 mi/h. If Miguel heads directly west, what are the boats resultant speed and direction? Diagram is not drawn to scale.

Answers

Refer to the diagram shown below.

The resultant speed of the boar is v, and its direction is θ degrees south of west.

Use the Pythagorean Theorem to calculate v.
v² = 14² + 2² = 200
v = √(200) = 14.1 mi/h

By definition,
tan θ = 2/14 = 0.1429
θ = tan⁻¹ 0.1429 = 8°

Answer: 14.1 mi/h; 8° south of west.

Replace y with x and x with y

[tex]x=\frac{y}{5} -2[/tex]

“Per cent” means “for each 100,” so 81% means “81 for each 100,” which translates to 81/100 as a fraction. 81 and 100 are what are called *coprime*, which means they don’t share any factors, so we can’t reduce the fraction any more.

A cone - shaped building has a height of 6 meters and a base with a diameter of 10 meters. The building will be filled with road salt that costs $25 per cubic meter. How much will it cost to fill the building with road salt? Use 3.14 for π Round to the nearest hundredth HELP ME ASAP!!!!

Answers

The formula for the volume of a cone is
.. V = (1/3)*π*r^2*h
The radius (r) is half the diameter, so is 5 m. Fill in the numbers and do the arithmetic.
.. V = (1/3)*3.14*(5 m)^2*(6 m) = 157 m^3

The cost will be $25 for each of those cubic meters, so is
$25*157 = $3925.00.

Formula
V= (1/3) pi r^2 h
r = d/2 = 10/2 = 5
h = 6
pi = 3.14
V = (1/3) * 3.14 * 5^2 * 6
V = (1/3) * 471
V = 157 cubic meters.

1 cubic foot cost $25
157 cubic feet cost x Cross multiply.

x = 25 * 157
x = 3925 dollars.
