Gomez found the masses of three rocks for a science project. The first rock had a mass of 19.28 grams the second rock had a mass of 25.3 grams and the third rock had a mass of 46.3 grams. How much greater was the mass of the third rock than the combiend mass of the other two rocks.

Answers

Answer 1

Answer:

Answer:

1.72 grams.

Step-by-step explanation:

We have been given that Gomez found the masses of three rocks for a science project. The first rock had a mass of 19.28 grams the second rock had a mass of 25.3 grams and the third rock had a mass of 46.3 grams.

First of all, we will add the masses of 1st and 2nd rock to find the combined mass of both rocks.

$\text{Combined mass of 1st and 2nd rock}=\text{19.28 g+25.3 g}$

$\text{Combined mass of 1st and 2nd rock}=\text{44.58 g}$

Now we will subtract the combined mass of both rocks from the mass of 3rd rock.

$\text{Difference of mass }=\text{46.3 g}-\text{44.58 g}$

$\text{Difference of mass }=\text{1.72 g}$

Therefore, the mass of the 3rd rock is 1.72 grams greater than the combined mass of the other two rocks.

Answer 2

Answer: 1.72 because rocks 1 and 2 add up to 44.58 46.3-44.58=1.72

What steps should be taken to calculate the volume of the right triangular prism? Select three options

Answers

Answer:

1st, 4th and 5th options are correct.

Step-by-step explanation:

Please find the attachment.

We are asked to choose three steps to calculate the volume of the given right triangular prism.

We know that base of triangular prism is triangle. The volume of triangular prism is area of base times height of the prism.

Let us find area of triangular base using area of triangle formula.

$A=(1)/(2)bh$ , where,

b = Base length,

h = Height of triangular base.

Therefore, 1st option is correct.

Upon substituting the base length (8 m) and height (14 m), we will get:

$A=(1)/(2)(\text{8 m}* \text{14 m})$

$A=\text{4 m}* \text{14 m}$

$A=56\text{ m}^2$

Therefore, 4th option is correct.

The volume of the prism would be area of base times height of prism (7 m) as:

$\text{Volume of the prism}=(56\text{ m}^2)* 7\text{ m}$

$\text{Volume of the prism}=392\text{ m}^3$

Therefore, 5th option is correct as well.

To calculate the volume of a triangular prism, measure the width and height of a triangular base, then multiply the base by the height by 1/2 to determine the triangle's area. Next, measure the height of the triangular prism and multiply this by the triangle's area to get the volume
