The length of a rectangle is 71/2 inches and the width is 23/4 inches. What is the ratio, using whole numbers, of the length to

Over [174]

Answer:

142:23

Step-by-step explanation:

The length of the rectangle is given as 71/2 while its width is 23/4

We are required to determine the ratio of the length to the width;

length:width

(71/2):(23/4)

(71/2)/(23/4)

71/2 * 4/23 = 142/23

The ratio of the length to the width is thus;

Answer:

C) the factory produces 25 chairs per hour

Step-by-step explanation:

Let's find the rate of change (slope):

$let:\\(x1,y1) =(2,50)\\(x2,y2)=(4,100)\\m=\frac{100-50}{4-2} =\frac{50}{2} =25 \\$

Find the area of parallelogram ABCD given m A = 30 and the following measures.

Nuetrik [128]

Answer: SECOND OPTION

Step-by-step explanation:

The area of a parallelogram can be calculated with this formula:

$A=bh$

Where "b" is the of one base and "h" is the height.

You can observe in the figure that "b" and "h" are:

$b=AB=4\sqrt{2}ft\\\\h=AX=3ft$

Then, substituting these values into the formula, you get that the area of the given parallelogram is:

$A=(4\sqrt{2}ft)(3ft)\\\\A=12\sqrt{2}ft^2$

This matches with the second option.
