Answer:
-a-13
Step-by-step explanation:
-2 * (a+3)
-2a - 6 -7 + a
-2a+a = -a
-6-7= -13
-a - 13
Answer:
Number of 1/8 cups of sugar needed = 2
Number of 1/8 cups of whole wheat flour needed = 6
Number of 1/8 cups of all purpose flour needed = 4
Step-by-step explanation:
Recipes Kelly needs:
Sugar = 1/4 cups
Whole wheat flour = 3/4 cups
All purpose flour = 1/2 cups
She could only find her ⅛ cup measuring cup.
How many ⅛ cups will she need for each ingredient?
Number of 1/8 cups of sugar needed = cups of Sugar needed / 1/8 cups
= 1/4 ÷ 1/8
= 1/4 × 8/1
= 8/4
= 2
Number of 1/8 cups of sugar needed = 2
Number of 1/8 cups of whole wheat flour needed = cups of whole wheat flour needed / 1/8 cups
= 3/4 ÷ 1/8
= 3/4 × 8/1
= 24/4
= 6
Number of 1/8 cups of whole wheat flour needed = 6
Number of 1/8 cups of all purpose flour needed = cups of all purpose flour needed ÷ 1/8 cups
= 1/2 ÷ 1/8
= 1/2 × 8/1
= 8/2
= 4
Number of 1/8 cups of all purpose flour needed = 4
Answer:
0.02% probability a password chosen at random is 7654
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the numbers are chosen is important. For example, 7654 is a different password than 6754. So the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
What is the probability a password chosen at random is 7654?
Only one desired outcome(password 7654), so 
Total outcomes:
4 numbers from a set of 10. So
Probability:
0.02% probability a password chosen at random is 7654
Answer:
20 hours
Step-by-step explanation:
52/8 = $6.5/hour
130 / 6.5 = 20
20 hours
The area is length x width which means it would be 14 x 8
14 x 8 = 112 so the area of the rectangle is 112 square ft.
