Answer:
23
Step-by-step explanation:
because 460 divided by 20 is 23 so the car gets 23 mpg because 460 represents miles and 20 represents gallons of gas
The length of the table is 15.14 inches.
- Let the length of the table be L.
-
Let the width of the table be W.
<u>Given the following data:</u>
- Area of table = 108 square inches
Translating the word problem into an algebraic equation, we have;
W = L - 8
To find the length of the table;
Mathematically, the area of a rectangle is given by the formula;
Substituting the values into the formula, we have;
Solving the quadratic equation by using the quadratic formula, we have the following values;
L = 15.14 or -7.14
We would choose the positive value.
Therefore, the length of the table is 15.14 inches.

Answer:
x = 10.75
Step-by-step explanation:
To find the value of x, we need to know the equation for the perimeter of a rectangle. This equation is:
P = 2L + 2W
Where P is the perimeter, L is the length, and W is the width.
We are given P = 84, L = 3x -1 , and W = x. Now we just plug these values in and solve for x.
P = 2L + 2W
84 = 2 ( 3x - 1 ) + 2 ( x )
84 = 6x - 2 + 2x
84 = 8x - 2
86 = 8x
86 / 8 = x
43 / 4 = x
(40 + 3) / 4 = x
10.75 = x
Hence, the value of x = 10.75.
Cheers.
Answer:
-7,-5.8,-4.6,-3.4,-2.2
Step-by-step explanation:
A geometric sequence must have a common ratio.
-3 / 1 = -3
9 / -3 = -3
-27 / 9 = -3
81 / -27 = -3
The first sequence is a geometric sequence.
-5.8 / -7 = 0.829...
-4.6 / -5.8 = 0.793...
The second sequence is not a geometric sequence (it is an arithmetic sequence with a common difference of 1.2).
Answer:
28
Step-by-step explanation:
Square: 4 * 4 = <u>16</u>
Small Triangle: 1 * 4 = 4 / 2 = <u>2</u>
Large Triangle: 5 * 4 = 20 / 2 = <u>10</u>
<u>16 + 2 + 10</u> = 28
