A Parallelogram is a shape with 4 sides that has two pairs of parallel sides. The opposite sides must have equal length. This is accurate for this shape.

A Rectangle is a shape with 4 sides that has four right angles. This is accurate for this shape.

A rhombus is a shape with 4 sides of equal length. This is not accurate for this shape.

The elevator maximum capacity is 1,000 pounds. Alex weighs 165 pounds and his helper Joan weighs 145 pounds. They have 50 pound

SVEN [57.7K]

Answer:

13

Step-by-step explanation:

If Alex and Joan's combined weight is 310, keep that in mind for each trip.

(1000-310)/50=answer

100-310= 690

690/50= 13.8

But you can't have a partial box, so it'll be only 13. You can't round up because then the total weight will be 10 over.

If a linear function has the points (0,1) and (5,8) on its graph, what is the rate of change of the function?

Harrizon [31]

A. 7/4
Rate of change is the same as slope, it is how the line has to go to get from the first to the second point. The slope function is y2-y1 / x2-x1. So we end up with 8-1/5-1 making 7/4

Answer:

<h3>The options A),B) and E) are correct</h3><h3>A) The given expression $p-\frac{2}{3}p$ is equivalent to $\frac{p}{3}$ </h3><h3>B) The given expression $\frac{p}{3}$ is equivalent to $\frac{p}{3}$ </h3><h3>E) The given expression $\frac{3p}{9}$ is equivalent to $\frac{p}{3}$ </h3>

Step-by-step explanation:

Given expression is $\frac{p}{3}$

<h3>To find the equivalent expressions to the given expression :</h3>

A) $p-\frac{2}{3}p$

Solving the expression $p-\frac{2}{3}p$

$p-\frac{2}{3}p=\frac{p(3)-2p}{3}$

$=\frac{3p-2p}{3}$

$=\frac{p}{3}$

<h3>∴ $p-\frac{2}{3}p=\frac{p}{3}$ </h3><h3>∴ The given expression $p-\frac{2}{3}p$ is equivalent to $\frac{p}{3}$ </h3>

B) $\frac{p}{3}$

<h3>∴ The given expression $\frac{p}{3}$ is equivalent to $\frac{p}{3}$ </h3>

E) $\frac{3p}{9}$

Solving it we get

∴ $\frac{3p}{9}=\frac{p}{3}$

<h3>∴ The given expression $\frac{3p}{9}$ is equivalent to $\frac{p}{3}$ </h3><h3> ∴ options A),B) and E) are correct</h3>
