If a 4-pound roast takes 150 minutes to cook, how long should a five-pound roast take
To roast a five-pound roast takes 187 minutes and 30 seconds at the same rate.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Given that,
A 4-pound roast takes 150 minutes
So,
4-pound ⇔ 150 minutes
Divide by 4 on each side,
1-pound ⇔ 150/4 minutes
Multiply by 5
5-pound ⇔ (150×5)/4 minutes
5-pound ⇔ 187.5 minutes
5-pound ⇔ 187 minutes and 30 seconds.
Hence "To roast a five-pound roast takes 187 minutes and 30 seconds at the same rate".

James was able to correctly name 11 major highways,4 mountains,86 major cities,and 9 bodies of water on a map.How many places on the map did James identify?Explain how you can use compatible numbers to help calculate the sum
Using the mathematical operation of addition, we know that James identified a total of 110 places on the map.
What is addiction? In math, addition is the process of adding two or more integers together. Addends are the numbers that are added, while the total refers to the outcome of the operation. It is one of the fundamental mathematical operations we employ on a daily basis. We employ number addition in a variety of contexts. When working with time or money, such as when adding up invoices and receipts, adding numbers is one of the most frequently used operations in daily life. The "+" sign is used to denote the addition of numbers (also called the plus symbol).The places which James correctly named on the map are:
11 major highways4 mountains86 major cities 9 water bodiesSo, to know how many of the places James identify, we should take the sum of all the places as follows:
11 + 4 + 86 + 9110Therefore, using the mathematical operation of addition, we know that James identified a total of 110 places on the map.

show one way to count from 82 to 512
To count from 82 to 512, you can do so by adding 10 to each preceding number starting from 82 until you reach 512.
Explanation:One way to count from 82 to 512 is to count by multiples of 10, which are also known as 'tens'. Begin by starting at the number 82 and adding 10 to get 92. Then, continue adding 10 to each resulting number. Continue this process until you reach the number 512. So, the sequence would look like this: 82, 92, 102, 112... until you eventually reach 512.
Note: This is just one simple method. Depending on the circumstances, you might want to count by other numbers. For instance, you could count by 20's or 50's. Each will yield a different number of steps, and some might be more efficient than others depending on the context.

A women who is 5 feet 5 inches tall is standing near the Space Needle in Seattle, Washington. She casts a 13-inch shadow at the same time that the Space Needle casts a 121 foot shadow. How tall is the Space Needle
To find the height of the Space Needle, a proportion is set up comparing the woman's height and shadow length to the Space Needle's shadow length. The calculation reveals that the Space Needle is approximately 60.83 feet tall.
Explanation:The student is asking to solve a proportion problem to determine the height of the Space Needle in Seattle, Washington. This is based on the concept of similar triangles where two figures have the same shape but different sizes, and the sides are in proportion. Since the woman who is 5'5" (which is equivalent to 65 inches) tall casts a 13-inch shadow, we can set up a proportion where the height of the Space Needle is to its shadow (121 feet or 1452 inches) as the woman's height is to her shadow. The proportion looks like this:
Height of Space Needle / 1452 inches = 65 inches / 13 inches
By cross-multiplication, we can solve for the height of the Space Needle:
Height of Space Needle * 13 inches = 65 inches * 1452 inches
Height of Space Needle = (65 * 1452) / 13
Height of Space Needle = 9490 / 13
Height of Space Needle = 730 inches
To convert this back to feet, we divide by 12, since there are 12 inches in a foot:
Height of Space Needle = 730 inches / 12 inches/foot = 60.83 feet (approximately)
Therefore, the Space Needle is approximately 60.83 feet tall, based on the given shadows and the woman's height.
write the word sentence as an equation.
The quotient of two times a number k and -2.6 is 12\
The word sentence 'The quotient of two times a number k and -2.6 is 12' translates to the equation (2 × k) / -2.6 = 12. Solving for k gives k = -15.6.
The sentence describes 'the quotient of two times a number k and -2.6 is 12'. Quotient refers to the result of division. Therefore, the equation that represents this sentence is:
(2 × k) / -2.6 = 12
To find the value of k, you would multiply both sides by -2.6 and then divide by 2:
-2.6 × 12 = 2 × k => -31.2 = 2 × k
k = -31.2 / 2 => -15.6

Use conversion factors to convert . Write the factor you used . 5 quarts to cups
To convert 5 quarts to cups, multiply 5 by the conversion factor of 4 cups per quart, resulting in 20 cups.
Explanation:To convert from quarts to cups, you need to use a conversion factor. The conversion factor for converting quarts to cups is 1 quart = 4 cups. Therefore, to convert 5 quarts to cups, you need to multiply the number of quarts by the conversion factor.
The calculation is as follows:
Start with the number of quarts you have, which is 5.Multiply 5 quarts by 4 cups/quart (since there are 4 cups in a quart).The calculation will be 5 × 4 = 20.Therefore, 5 quarts is equal to 20 cups.

A rectangular lawn has an area of 153 square meters and a perimeter of 52 meters what are the dimensions of the lawn
The rectangular lawn's dimensions that match the given area (153 square meters) and perimeter (52 meters) are 17 meters in length and 9 meters in width.
Explanation:This problem is solved using the formulae for the area and the perimeter of a rectangle. The area is given by Area = length x width and the perimeter by Perimeter = 2 x (length + width). Because we know both the area and the perimeter of the rectangle, we have a system of two equations and two unknowns. Given that the area is 153 and the perimeter is 52, we can write the equations as follows: lw = 153 and 2l + 2w = 52.
By solving this system of equations, we find that the dimensions of the rectangle that satisfy these two equations are length = 17 meters and width = 9 meters. Therefore, the lawn's dimensions are 17 meters in length and 9 meters in width.

colton's recipe makes 2 dozen brownies. his recipe calls for 7/8 cup of vegetable oil. how much oil will colton need to make 6 dozen brownies?
Final answer:
Colton will need 2 5/8 cups of vegetable oil to make 6 dozen brownies. This is calculated by tripling the original required amount of 7/8 cup of oil needed for 2 dozen brownies.
Explanation:
Colton's recipe for brownies specifies that 7/8 cup of vegetable oil is needed to make 2 dozen brownies. To find out how much oil is required for 6 dozen brownies, we need to calculate the amount of oil for triple the original quantity since 6 dozen is three times 2 dozen. First, we set up a proportion where 2 dozen corresponds to 7/8 cup of oil.
Mathematically, we can find the amount of oil needed for 6 dozen by multiplying the amount of oil for 2 dozen by 3 (since 6 is three times larger than 2):
Multiply 7/8 cup by 3.
7/8 × 3 = 21/8 cups.
Convert 21/8 cups to a mixed number to get 2 5/8 cups.
Therefore, Colton will need 2 5/8 cups of vegetable oil to make 6 dozen brownies.
