A recipe uses cups of milk to make servings. If the same amount of milk is used for each serving, how many servings can be made using gallon of milk?

Answers

Answer:

128 servings

Step-by-step explanation:

A recipe Uses 1 1/4 cups of milk to make 10 servings if the same amount of milk is used for each serving how many servings can be made using one gallon of milk

Cups of milk : number of servings = 1 1/4 cups : 10 servings

One gallon of milk = 16 cups

Let x = number of servings

Cups of milk : number of servings = 16 cups : x

Equate both ratios

1 1/4 : 10 = 16 : x

5/4 ÷ 10 = 16/x

5/4 × 1/10 = 16/x

5/40 = 16/x

1/8 = 16/x

Cross product

1 * x = 8 * 16

x = 128 servings

Number of servings = 128

fill in the missing term in the equation.

Triangle A B C. Angle C is 90 degrees. Hypotenuse side A B is c, C B is a, C A is b. Solve the right triangle shown in the figure.

Side B C = 1.3 millimeters, Angle A = 66.6 degrees, Side A C = 3.0 millimeters

Answers

*see attachment for the figure

Answer:

Side BC = 3.0 millimeters, Angle A = 66.6 degrees, Side AC = 1.3 millimeters

Step-by-step explanation:

Given:

C = 90°

B = 23.4°

AB = c = 3.3 mm

Required:

<A, BC, and AC

Solution:

✔️m<A = 180° - (90° + 23.4°) (sum of triangle)

m<A = 66.6°

✔️To find BC and AC, apply trigonometric function:

Reference angle = 23.4°

Hypotenuse = 3.3 mm

Opposite = AC

Adjacent = BC

✅Apply CAH to find AC:

Cos 23.4 = Adj/Hyp

Cos 23.4 = BC/3.3

3.3 × Cos 23.4 = BC

3.02859027 = BC

BC ≈ 3.0 mm

✅Apply SOH to find AC:

Sin 23.4 = Opp/Hyp

Sin 23.4 = AC/3.3

3.3 × Sin 23.4 = AC

1.31058804 = AC

AC ≈ 1.3 mm

Answer: B bc=3.0mm, A=66.6, AC=1.3mm

Mr. Davies plans to place an aquarium on a shelf in his living room. The length of the shelf is inches, and the aquarium is inches long. Which estimation is best for centering the aquarium on the shelf?

Answers

The question is incomplete as the length of the shelf and aquarium isn't given. However, steps to take in other to make the estimation of centering the aquarium on the shelf would be described.

Answer:

Kindly check explanation

Step-by-step explanation:

Let :

Lenght of shelf = x

Length of aquarium = y

Usually, the length of shelf will be > length of aquarium

The shelf will have the right and left hand side ;

Subtract Length of aquarium from length of shelf and divide the difference by 2 ;

(x - y) / 2 ; this will give the space or length left on either side of the shelf with the aquarium centered in the middle.

Hence, the aquarium should be placed at (x - y) / 2 meters either to the right or left of the shelf.

Just input the omitted values of shelf length and aquarium length to obtain the solution.

Answer:

y = 2x + 3

Step-by-step explanation:

We need to find m and b

Let's input the first 2 points (3, 9) and (5, 13) into y = mx + b

9 = m*3 + b

13 = m*5 + b

subtract the first from the second

13 - 9 = m*5 + b - (m*3 + b)

4 = m*2

m = 2

Now let's input m = 2 into 9 = m*3 + b

9 = 2*3 + b

9 = 6 + b

3 = b

So the final relationship is y = 2x + 3

We can verify that the other two points (8, 19) and (11, 25) also conform to this relationship.

Aaaa I had problems with this too, the answer is y = 2x + 3
