PLEASE HELP ME! 5TH GRADEThe solid figure is separated along the dotted line into two rectangular prisms. What are the volumes of the two rectangular prisms? What is the volume of the solid figure? Use the drop-down menus to show your answer. A solid is made up of 2 rectangular prisms. The total length of the solid is 20 inches. First rectangular prisms has a height of 5 inches, and width of 4 inches. Second rectangular prisms have 4 inches, a height of 8 inches, and a width of 4 inches. The volume of two rectangular prisms are Choose... cubic inches and 128 cubic inches. The volume of the solid figure is Choose... cubic inches.

Answers

The volume of the solid figure is the amount of space in it

The volume of the solid figure is 448 cubic inches

How to determine the volume of the figures?

For the first rectangular solid, we have:

Height = 5 inchesWidth = 4 inchesLength = 16 inches

So, the volume is:

Volume = 5 * 4 * 16 cubic inches

Volume = 320 cubic inches

For the second rectangular solid, we have:

Height = 8 inchesWidth = 4 inchesLength = 4 inches

So, the volume is:

Volume = 8 * 4 * 4 cubic inches

Volume = 128 cubic inches

The volume of the solid figure is then calculated as:

Volume = 320 cubic inches + 128 cubic inches

Volume = 448 cubic inches

Hence, the volume of the solid figure is 448 cubic inches

I have attached an image showing the triangle with angle and distance depicted in the question.

Answer:

151 miles

Step-by-step explanation:

We have to first find the unknown angle in the triangle.

Sum of angles in a triangle is 180°.

Thus, if we call angle at Norfolk A, we have;

A = 180 - (83 + 31)

A = 66°

Using sine rule, we can find the distance which we will term as a.

Thus;

a/sin 83 = 139/sin 66

a = (139 × sin 83)/sin 66

a = 137.963915/0.913545

a ≈ 151 miles

3 ^ -(sqrt 3)

Answers

Answer:

Step-by-step explanation:

y = 3 ^ - sqrt(3)

y = -sqrt(3) * log(3)

Log (3)= 0.47712

- sqrt(3) = - 1.732

y = 0.47712 * -1.732

y = - 0.82637

The y really has no meaning. I just used it so I could get from 1 line to the next.

Look carefully at how that - sqrt(3) was handled. You are not taking the square root of -3.
