Answer:
1200
Step-by-step explanation:
Step 1 convert pounds to ounces
1 pound = 16 ounces
So to convert pounds to ounces we multiply by 16
1500 * 16 = 24000
So there are 24000 ounces in 1500 pounds
Step 2 Find how many 20 ounce containers he can fill.
To find out how many 20 ounce containers he can fill we divide the total amount of ounces of butter that he has by 20
So answer = 24000/20
24000 / 20 = 1200
Therefore he can fill 1200 20 - ounce containers
What is the ratio of 50 cents to $1.20 (in simplest form)?
Answer:
5:12
Step-by-step explanation:
$1.20 = (1x100 + 20) cents = 120 cents
You get a ratio of 50:120.
Since both are divisible by 10, divide both sides by 10.
You get 5:12.
Since 5 and 12 share no common factors other than 1, this is the simplest form.
Kristin is 30 years old. Her son Reggie is 10 years less than half her age. Which numerical expression represents Reggie’s age?
Answer:

Answer:
R= K/2 - 10
Explanation:
30/2 - 10 = 15 - 10 = 5 years old for Reggie and Kristen's age = K=30.

The top deck of a boat is 9 feet above the surface of a lake, while the bottom of the boat is 24 feet below the surface of the lake.
What is the vertical distance between the top deck and the bottom of the boat?
Drag and drop the correct value into the box to complete the statement.
The vertical distance is ____ feet.
Hi there!
[tex]\large\boxed{33 \text{ feet}}[/tex]
We can find the distance with this expression:
Height(top deck) - Height(bottom) = distance
The top deck has a height of positive 9 feet, while the bottom of the boat has a height of -24 feet since it is BELOW the surface of the lake.
Thus:
9 - (-24) =
Subtracting a negative becomes a plus, so:
9 + 24 = 33 feet.

Answer:
x = 70 degrees, y = 35 degrees.
Step-by-step explanation:
The angle marked x is a central angle, so its measure is the same as the measure of the intercepted arc.
The angle marked y is an inscribed angle, so its measure is half the measure of the intercepted arc.

Answer:
x = 4.
Step-by-step explanation:
4 - 5x = 12 - 7x
4 - 5x + 7x = 12 - 7x + 7x
4 + 2x = 12
4 - 4 + 2x = 12 - 4
2x = 8
x = 8/2 = 4.
Answer:
4-5x=12-7x
-5x+7x=12-4
2x=8
x=8/2
x=4

Ray made a toolbox with the dimensions shown to store garden tools. What is the volume of the toolbox?
Answer:61
Step-by-step explanation:
As per the dimensions shown to store garden tools, the volume of Ray's toolbox is 7200 cubic units.
In order to determine the volume of Ray's toolbox, we need to use the formula for calculating the volume of a rectangular prism, which is
V = length × width × height.
Given the dimensions provided, the height of the toolbox is 12 units, the width is also 12 units, and the length is 50 units.
Now, let's substitute these values into the formula:
V = 12 units (height) × 12 units (width) × 50 units (length)
V = 12 × 12 × 50
V = 7200 cubic units
