I would say yes, the rectangles are similar!
Both of the rectangles have a scale factor of 2.5
If you divide 10 and 4 (the smaller sides of the rectangle) you will see that the larger rectangle is 2.5x bigger than the smaller one!
Same with the longer side. 20 divided by 8 is 2.5:)

What’s the area of a rectangle measuring 13in tim12 in ?

Evgesh-ka [11]

Answer:

156 sq in

Step-by-step explanation:

If you have a rectangle measuring 13 inches by 12 inches, you will consider the side with 13 inches as the length of the rectangle and the one with 12 inches as the width of the rectangle.

The area of a rectangle is obtained by multiplying the length by the width... so, you'll get:

A = 13 in x 12 in = 156 square inches

Which is a correct interpretation of the slope of the line in this graph?

Vilka [71]

Answer:

Option C. the volume of water in the tank is decreasing by 0.4L per hour

Step-by-step explanation:

step 1

Find the slope

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

$A(2,8)\ B(7,6)$

Substitute the values

$m=\frac{6-8}{7-2}$

$m=\frac{-2}{5}=-0.40\frac{liters}{hour}$

The slope is negative

is decreasing

That means------> the volume of water in the tank is decreasing by 0.4L per hour

The bed of a truck is stacked with with boxes of paper. The boxes are stacked 5 boxes deep by 4 boxes high by 4 boxes across

marysya [2.9K]

Answer:

Step-by-step explanation:

The boxes are stacked 5 boxes deep by 4 boxes high by 4 boxes across, then there are $5\cdot 4\cdot 4=80$ boxes in total.

The mass of 1 box of paper is 22.5 kilograms, so 80 boxes weigh $22.5\cdot 80=1800$ kilograms.

When the driver is in the truck, the mass is 2948.35 kilograms, then the total mass is

$2948.35+1800=4748.35\ kg.$

Let n be the number of boxes of paper the driver must deliver at the first stop. Their weigth is 22.5n kg and the weight of the truck without n boxes is

$4748.35-22.5n\ kg.$

Trucks with a mass greater than 4700 kilograms are not allowed over the bridge, thus

$4748.35-22.5n48.35,\\ \\n>\dfrac{967}{450}=2\dfrac{67}{450}.$

Hence, the driver must deliver at least 3 boxes at the first shop.

??? quadrilateral abcd ??? is inscribed in this circle. what is the measure of angle c? enter your answer in the box. ?? a quadr

Readme [11.4K]

Answer: The measure of angle C is 107 degrees.

When, you have a quadrilateral inscribed in a circle, measure of the opposites sides are supplementary (they add to 180). Therefore, we can write and solve the following equation with angles D and B to find the value of x in the problem.

3x + 9 + 2x - 4 = 180
5x + 5 = 180
5x = 175
x = 35

Now, input x = 35 into the expression for A to find that the measure of angle A is 73.

Since A and C are supplementary:
A + C = 180
73 + C = 180
C = 107
