a cookie recipe calls for a half cup of chocolate chips per 3 dozen cookies. How many cups of chocolate chips should be used for 10 dozen cookies?

The number of cups of chocolate chips that should be used for 10 dozen cookies is 1 2/3 cups.

Based on the information given, the expression to solve the question will be:

0.5/3 = x/10

Cross multiply

3 × x = 0.5 × 10

3x = 5.

x = 5/3

x = 1 2/3 cups

Therefore, the number of cups of chocolate chips that should be used for 10 dozen cookies will be 1 2/3 cups.

To answer this question, you should set up a proportion that demonstrates the ratio of chocolate chips to cookies.

36 and 120 are used because 1 dozen=12.

Cross multiply and solve for x to get the answer.

The answer is cups.

A 12-foot ladder rests against the side of a house. The base of the ladder is 3 feet away from the side of the house. How high above the ground is the top of the ladder? Round to the nearest tenth of a foot.

Using Pythagorean's Theorem we know that a^2 + b^2 = c^2

C is the length of the ladder, and we are given one of the sides, let's call that side b

_________

we have a^2 + b^2 = c^2, and a^2 = c^2 - b^2, so a = √ c^2 - b^2

_________ ______ ____

a = √12^2-3^2 = √ 144-9 = √ 135 = 11.61895

so the top of the ladder is 11.6 feet above the ground

C is the length of the ladder, and we are given one of the sides, let's call that side b

_________

we have a^2 + b^2 = c^2, and a^2 = c^2 - b^2, so a = √ c^2 - b^2

_________ ______ ____

a = √12^2-3^2 = √ 144-9 = √ 135 = 11.61895

so the top of the ladder is 11.6 feet above the ground

This question is asking about the Pythagorean Theorem (A^2 + B^2 = C^2)

You know the length of the hypotenuse (this is 12 feet, the length of the ladder, which is C), you also know A, 3 feet from the side of the house.

So we have to plug into the formula what we know 3^2 + B^2 = 12^2, or 9 + B^2 = 144. By rearranging the formula you get 144 - 9 = B^2. Once you solve for B^2 you can take the square root to get B. (It's 11.6!)

The distribution of annual profit at a chain of stores was approximately normal with mean μ = $66,000, standard deviation σ = $22,000. The stores with profits in the top 5 percent each had a reward party for the employees to celebrate. What is closest to the minimum annual profit for a store that had a reward party? Round to the nearest thousand dollars.

Answer:

$102,000.

Step-by-step explanation:

We have been given that the distribution of annual profit at a chain of stores was approximately normal with mean μ = $66,000, standard deviation σ = $22,000. The stores with profits in the top 5 percent each had a reward party for the employees to celebrate.

We will use z-score formula and normal distribution table to solve our given problem.

Top 5% of data would be equal to 95% and more.

Let us find z-score corresponding to 95% or 0.95 using normal distribution table.

Upon rounding to nearest thousand dollars, we will get:

Therefore, the closest minimum annual profit, for a store that had a reward party, would be $102,000.

Answer:

$102,000

A 4-digit number ends in 3. If you put the number 3 in the first position, the number will decrease by 738. Find the original 4-digit number.

Answer:

4153

Step-by-step explanation:

Let the original number be [a is the number of thousands, b - the number of hundreds, c - the number of tens, 3 - the number of ones]

If you put the number 3 in the first position, the number will be

New number is 738 less than old number.

When you subtract from 3 some number c and get 8, then you have to lend one ten and subtract this number c from 13. So, 13-5=8. Thus, c=5. Remember about lending! Now when you subtrat from 4 (not 5 because of lending) some number b and get 3, then b=1. Now when you subtract from 1 some number a and get 7, then you have to lend 1 from the number of thousands and subtract a from 11 to get 7, thus 11-4=7 and a=4.

We get initial number 4153 and rewritten number 3415. Check the difference:

4153-3415=738

4153
