Choose the graph that represents the following system of inequalities:

y ≥ −3x + 1
y ≥ 1 over 2x + 3

In each graph, the area for f(x) is shaded and labeled A, the area for g(x) is shaded and labeled B, and the area where they have shading in common is labeled AB.

Graph of two intersecting lines. Both lines are solid. One line f of x passes through points negative 2, 2 and 0, 3 and is shaded above the line. The other line g of x passes through points 0, 1 and 1, negative 2 and is shaded above the line.

Answer 1

Answer:

FIRST.

64 square inches matches to a cross section parallel to the base of a right rectangle prism that is 3 inches long, 7 inches wide, and 11 inches tall

This is shown in the first figure below. A right rectangular prism where every edge connecting its base and the opposite face makes right angles with both faces. Since the tall is the side that measures 11 inches, then the base is formed by 3 inches long and 7 inches wide. Therefore, the area of this shape can be found as the area of a rectangle, which is: 21 in squared.

SECOND.

64 square inches matches to a cross section parallel to the base of a cube whose edges are 8 inches long.

This is shown in the second figure below. A cube is a prism whose sides all have the same length and in this case is 8 inches. We name cross section is to the slice that cuts through a solid. If the cross section is parallel to the base of a cube, then it forms a square with length . Therefore, the area of this shape can be found as the area of a square, which is: 64 in squared.

Third.

7 square inches matches to a cross section passing through the diagonal of opposite faces of a cube with edges that are 7 inches long and a diagonal that is approximately 10 inches

This is shown in the third figure below. As you can see, the cross section passes through the diagonals of the base and the top of the cube that are two opposite faces. This form a rectangle having sides  where:

So: 70 in squared

FOURTH.

300 square inches matches to a cross section perpendicular to the base and passing through the diagonals of the base and opposite face of a right rectangular prism that is 24 inches wide, 7 inches long, and 12 inches tall and measures 25 inches along the diagonal of the base.

This is shown in the fourth figure below. The cross section passes through the diagonals of the base and the top of the right rectangular prism. They are opposite to each other, so the shape of the cross section is a rectangle whose sides are  where:

So: 300 in squared.

Explain how to decompose a triangle into congruent triangles. How do those decomposed pieces relate to the area of the rectangle?

Answers

Answer: You would divide the rectangle into half, to form two congruent triangles. When you multiply the area of 1 of the triangles, it gives you the area of both triangles, and so the area of the triangle as a whole.

Step-by-step explanation:

First you would have to divide the rectangle into half, to form two congruent triangles. Then if you multiply the area of 1 of the triangles, it will give you the area of both triangles, and so the area of the triangle as a whole.

Additionally, she was asking students from

Katie draws 14 pictures in 24 minutes. At this rate, how many pictures can she draw in 312 minutes?

Answers

Answer:

Hi there! the answer should be: Katie can draw 182 pictures in 312 minutes

Step-by-step explanation:

312 ÷ 24 = 13

14 x 13 = 182

hope this helped qwq

katie can draw 182 pictures in 312 minutes.

first, we should find out how many pictures she can draw in 1 minute. 14/24 equals 0.583333... pictures per minute. 0.583333... times 312 equals 182 pictures (i used a calculator so this should be correct). hope this helps!
