Answer:
The probability of rolling a sum greater than 1 when rolling two fair numbered cube is 1 or 36/36.
Step-by-step explanation:
There is no 1 as a sum when rolling two fair numbered cubes, so all the sums will be greater than 1.
The single digit to the left of the vertical line is the tens units, the numbers to the right are the ones.
The scores above 64, would be 65, 73, 74, 77, 87, 88, 91, 93, 93, 97, 99, 99
A total of: 12 scores.
Answer:
x = 2.5 inches. Or
x = 5/2
Step-by-step explanation:
Length: 7 + 2x
Width: 5 + 2x
Note that you have to add x at each end of the picture and onto each part of the width.
The entire area is 120 square inches.
Formula
L*W = Area
(2x + 7)(2x + 5) = 120
Solution
4x^2 + 10x + 14x + 35 = 120 Subtract 120 from both sides. Add xs
4x^2 + 24x + 35 - 120 = 0
4x^2 + 24x - 85 = 0 Factor
(2x + 17)(2x - 5)
2x + 17 has no meaning. It will give - 8.5 which is not possible.
2x - 5 =0
2x = 5 Divide by 2
x = 5/2
x = 2.5
Note: I don't know which one the computer is looking for.
Answer:
The answer is c and we'll use c to get the actual answers.
A) n + q = 104
B) .05n + .25q = 22 we'll multiply B) by -4
B) -.2n -1q = -88 then we add A)
A) n + q = 104 which equals
.8n = 16
n = 20 nickels
q = 84 quarters
20 nickels = $1
84 quarters = $21
Successful!!!
Step-by-step explanation:
Her electricity bill will be of 14256 pence.
