<span>Let l equal the length of the rectangle
</span><span>width of a rectangle is 10 mm shorter than its length
</span>
<span>a. Write an expression for the width in terms of the length?
</span> w = l - 10
<span>b. Write an equation for the perimeter in terms of l.
P = l + l + (l-10) + (l-10)
P =4l - 20
</span><span>c. Solve the equation, clearly indicating the length of the rectangle.
</span> P =4l - 20
244 = 4l - 20
4l = 244 + 20
4l = 264
l = 284/4
l = 66
<span>d. Solve for the width of the rectangle. Clearly indicate the width of the rectangle.
</span>w = l - 10
w = 66 - 10
w = 56
Answer:
256 sq cm
Step-by-step explanation:
cube is a three-dimensional figure with six congruent square faces. Since each face is congruent, each of the edges have the same length.
The cross-section described is shown below.
The cross-section is also a square which is congruent to the other faces of the cubes. Therefore, the edges of the cross-section will each measure 16 cm. Find the area by using the formula for the area.
A=lw
=(16cm) (16cm)
=256 sq cm
So, the area of the cross-section is 256 sq cm.

Step-by-step explanation:
A ratio is a comparison of two numbers. A ratio can be written using a colon, 8:12 , or as a fraction 8/12 . A rate is a comparison of two quantities which can have different units. For example 8 miles per 4 hours is a rate.
Answer:
Step-by-step explanation:
There are 6 blue marbles and 14 red marbles, so the ratio of blue marbles to red marbles
There are 1000 milliliters in a liter.
So to get to liters divide the number of milliliters by 1000.
4,873,800/1,000=4873.8
So your final conversion is 4873.3 L
