Nadine bought 5 quarts of oil for her car. How many fluid ounces is that?

Answers

Answer:

5 quarts is equal to 160 fluid ounces.

Step-by-step explanation:

Nadine bought 5 quarts of oil for her car. How many fluid ounces is that?

The relation between 1 quart and number of fluid ounces is :

1 quart = 32 fluid ounces.

So, 5 quarts will be = 5*32=160 fluid ounces.

Hence, we can say that Nadine bought 160 fluid ounces for her car.
1 quart = 32 fluid ounces.

So, 5 quarts = ? fluid ounces.

Lets solve to find ?. 

5 × 32 = 160

So, Nadine bout 160 fluid ounces (5 quarts) or oil for her car.

A dartboard consists of two concentric circles. The probability of hitting the inner circle is64%. If the outer circle has a diameter of 20 inches, what is the radius of the inner circle?

2 inches
4 inches
8 inches
16 inch

Answers

Given:
Diameter of outer circle = 20 inches.

We need to find the Area of the outer circle to get the radius of the inner circle.

Area = πr²

Outer circle Area = 3.14 * (10in)² = 314 in²

314 in² * 64% probability = 200.96 in² Area of the inner circle.

200.96 in² = 3.14 * r²
200.96 in² / 3.14 = r²
64 in² = r²
√64 in² = √r²
8 in = r

radius of inner circle is 8 inches.

123 grams is rounded to nearest whole. Write down the minimum possible mass it could have been.

Answers

Since we want the minimum value we are going to be rounding up from a smaller number. So we know the whole number will be 122. Now we find the smallest number that will round up which is .5. Answer is 122.5

HELP FAST PLEASE What is the value of the function at X=-3?
O y = 4
O y = 0
O y = 3
0y=-3

Answers

Answer:

To determine the value of the function at x = -3, we need to substitute -3 into the given function and evaluate it. Let's go through each option one by one:

1. y = 4: If this is the function, then substituting x = -3 would give us y = 4. However, this option does not match the given function.

2. y = 0: Substituting x = -3 into this function would give us y = 0. However, this option does not match the given function either.

3. y = 30: Substituting x = -3 into this function would give us y = 30. However, this option does not match the given function.

4. y = -3: Substituting x = -3 into this function would give us y = -3. This option matches the given function, so the value of the function at x = -3 is indeed y = -3.

Therefore, the correct answer is:

y = -3
