The difference, to the nearest gram, of the masses of the rectangular

prisms is 1393.2 grams.

<h3>What is the volume of the rectangular prism?</h3>

The volume of the rectangular prism is the product of the length, breadth, and height of the given prism.

Volume of rectangular prism = (length x width x height)

Joe has a rectangular prism made of aluminum and a rectangular prism made of lead.

Each rectangular prism has a height of 6 cm, length of 9 cm, and width of 3 cm.

The volume of a rectangular prism made of aluminum = (length x width x height)

= $6 \times 9\times 3\\\\162$

The volume of a rectangular prism made of lead= (length x width x height)

= 162 cubic cm

We know that mass = density x volume

The density of aluminum is approximately 2.70.

mass = 2.70 x 162

= 437.4 grams

The density of lead is approximately 11.3 cm3

mass = 11.3 x 162

= 1830.6 grams

The difference, to the nearest gram, of the masses of the rectangular

prisms 1830.6 - 437.4 = 1393.2 grams

If TSP and PSW are supplementary, and TSP is two times as large as mPSW, what is mTSP?

Burka [1]

Answer:

$\huge\boxed{120 \textdegree}$

Step-by-step explanation:

In order to solve for m∠TSP, we can use basic angle relationships and equations.

Let’s assume m∠PSW is $x$ °

We know that if two angles are supplementary, their angle lengths will add to 180°.

We also know that m∠TSP is twice as large as PSW. Since PSW is represented as x°, TSP will be 2x°.

We can add these two angles together and get 180°. Then you can solve for x (PSW)

$x+2x=180$
$3x=180$
$x=60$

So we know that x (PSW) is 60°. However, the question asks for the measure of TSP. We know that TSP is twice as large as PSW, so we can multiply PSW (60) by 2.

$60 \cdot 2 = 120$

So m∠TSP is 120°.

Hope this helped!

Based on a website, Ellen knows that 5 slices of pizza have 1,900 calories.

forsale [732]

Answer:

part A-760

part b-she eats halve a slice of pizza because there is 380 calories in a slice of a pizza and 380 divided by 2 is 190 so she only eats halve.

part c- 1=380

A 12 cm x 2 cm rectangle sits inside a circle with radius of 8 cm.

hammer [34]

Answer:

Diagram was not given.

Still I had drawn it, hope may it will helpful to you. So as per my diagram I had solved the sum.

The area of the shaded region is 176.96 ≈ 178 cm²

Step-by-step explanation:

Given:

radius of the circle = r = 8 cm

length of the rectangle = L = 12 cm

breadth of the rectangle = B = 2 cm

To Find:

Area of shaded region = ?

Solution:

$\textrm{Area of rectangle} = Length\times Breadth\\= L\times B\\= 12\times 2\\= 24\ cm^{2}$

$\textrm{Area of Circle} = \pi \times (radius)^{2} \\=\pi \times r^{2}\\=3.14\times 8^{2}\\=200.96\ cm^{2}$

Now, The Area of Shaded region will be

$\textrm{Area of Shaded region}=\textrm{Area of Circle}-\textrm{Area of Rectangle}\\=200.96 - 24\\=176.96\ cm^{2} \\=178\ cm^{2}\........... \textrm{Rounded to tenth}$

The area of the shaded region is 176.96 ≈ 178 cm²
