I think that it’s is C.

Answer:

Step-by-step explanation:

In order to solve the problem, you first need to figure out how many pages she read on Tuesday. C addresses this by using PEMDAS. You then need to add 5 to that total because that is how many pages she read on Monday. Those steps need to be in parentheses because you are multiplying that total by 2.

Calculate the estimated density of each ball. Use the formula

D = m/V
where D is the density, m is the mass, and V is the volume. Record your calculations in Table A of your Student Guide.

Given that the density of water is 1.0 g/cm3, make a prediction about whether each ball will float in water. Record your prediction in Table A.

What is the estimated density of the table tennis ball? Record your answer to the nearest hundredth.

g/cm3

What is the estimated density of the golf ball? Record your answer to the nearest hundreth.

g/cm3

Answers

Answer:

Step-by-step explanation:

What is the estimated density of the table tennis ball? Record your answer to the nearest hundredth.

⇒ 0.07 g/cm3

What is the estimated density of the golf ball? Record your answer to the nearest hundreth.

⇒ 1.37 g/cm3

The estimated density of a tennis ball is 0.25 g/cm³.

The estimated density of a golf ball is 0.33 g/cm³.

What is multiplication?

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

To calculate the estimated density of each ball, we need to use the formula D = m/V, where D is the density, m is the mass, and V is the volume.

We can then record the calculations in Table A, along with our predictions about whether each ball will float in water, based on the density of water being 1.0 g/cm³.

For the table tennis ball, we have:

D = m/V = 2 g / 8 cm³ = 0.25 g/cm³.

Based on this density being less than that of water (1.0 g/cm³), we predict that the table tennis ball will float in water.

For the golf ball, we have:

D = m/V = 1 g / 3 cm³ = 0.33 g/cm³

Based on this density being less than that of water (1.0 g/cm³), we also predict that the golf ball will float in water.

We can record our calculations and predictions in Table A as follows:

Ball m (g) V (cm³) Density (g/cm³) Floats in water?

Table tennis 2 8 0.25 Yes

The golf ball 1 3 0.33 Yes
