Answer:
Step-by-step explanation:
Area of the figure = Area of rectangle with dimensions 48 in and 32 in + Area of triangle with base 48 in and height 12 in.
L = 20 and W = 15
Explanation:
Let's review what is known about the rectangle in question - the area is 300 cm squared and the ratio of the Length to the Width (which I'll shorten to L and W) is 4:3.
Let's start with the ratio. We know that they are related to each other - 4 of a basic unit of length for L and 3 of that same basic unit of length for W. So we can say that
L =
4
x
and W =
3
x
We also know from the formula for the area of a rectangle that LW = Area of the rectangle. Substituting in the terms with the x's in them gives us
(
4
x
)
(
3
x
)
=
300
so let's solve for x:
12
x
2
=
300
x
2
=
300
12
=
25
x
=
√
25
=
5
(ignoring the negative root since that makes no sense in this application)
Substituting x back into our equations for L and W, we get
L =
4
(
5
)
=
20
and W =
3
(
5
)
=
15
Checking our work - there is a ratio of L:W of 4:3. And LW =
20
⋅
15
=
300

Answer:
$31.70
Step-by-step explanation:
In order to find the total monthly charge for the customer, you can set up an equation using two different variables and putting in the charges and number of calls for each.
Let 'x' = the number of in-state calls and 'y' = the number of out-of-state calls.
Equation: 0.03x + 0.11y + 10.75 = total
Since the customer made 350 minutes of in-state calls, x = 350 and 95 minutes of out-of-state calls, y = 95:
0.03(350) + 0.11(95) + 10.75 = total
$10.50 + $10.45 + $10.75 = $31.70
