30% is equal to 0.3 (found by dividing the percentage by 100). Then we multiply the cost of dinner, $85, by 0.3 to find an answer of $25.50.
Answer: $25.50
Step-by-step explanation:
to find the area more easily, you can divide the figure.
make a small rectangle from the upper part (a 5×6 rectangle) then a square from the lower part (a 5×5 square).
now you have a small rectangle, a big rectangle and a square.
small rectangle: 5×6=30
big rectangle: 15×5=75
square:5×5=25
30+75+25=130

Answer:
1/7
Step-by-step explanation:
We can use the slope formula(k=y₁-y₂/x₁-x₂) to solve this problem
k = 2-1/3-(-4) = 1/7
Answer:
2.33
Explanation:
First find the mean:
1 + 10 + 7 + 6 + 4 + 8 = 36
36 / 6 ( there are 6 total numbers) = the mean is 6
Then subtract the mean from each number:
1 - 6 = -5
10 - 6 = 4
7 - 6 = 1
6 - 6 = 0
4 - 6 = -2
8 - 6 = 2
(don't worry about the negatives)
5 + 4 + 1 + 0 + 2 + 2 = 14
14 / 6 ( again, there are 6 total numbers) = 2.33
