Answer: $393
Step-by-step explanation: (34’+ 30’+67’) x $3.00 = 131 x 3.00 = 393
Yup! We're all pretty good here.
1. First, let us define the width of the rectangle as w and the length as l.
2. Now, given that the length of the rectangle is 6 in. more than the width, we can write this out as:
l = w + 6
3. The formula for the perimeter of a rectangle is P = 2w + 2l. We know that the perimeter of the rectangle in the problem is 24 in. so we can rewrite this as:
24 = 2w + 2l
4. Given that we know that l = w + 6, we can substitute this into the formula for the perimeter above so that we will have only one variable to solve for. Thus:
24 = 2w + 2l
if l = w + 6, then: 24 = 2w + 2(w + 6)
24 = 2w + 2w + 12 (Expand 2(w + 6) )
24 = 4w + 12
12 = 4w (Subtract 12 from each side)
w = 12/4 (Divide each side by 4)
w = 3 in.
5. Now that we know that the width is 3 in., we can substitute this into our formula for length that we found in 2. :
l = w + 6
l = 3 + 6
l = 9 in.
6. Therefor the rectangle has a width of 3 in. and a length of 9 in.
Answer:
Center
Step-by-step explanation:
A diameter is a line segment whose endpoints are on a circle. It is a special type of chord because it must contain the center of the circle.
Answer:
x = 2
y = 149
Step-by-step explanation:
these two angles are equal to one another
(8x+15) = (7x+17)
solve for x
x = 2
two angles are supplementary
8x + 15 + y = 180
we know 8x+15 since x =2
8(2) + 15 + y = 180
16 + 15 + y = 180
31 + y = 180
solve for y
y = 180 - 31 = 149
please give brainist, you promised last time :)
