Percent means parts out of 100
70%=70/100=7/10
7/10 of x=28
'of' means multiply
7/10 x=28
multiply both sides by 10/7 to get rid of fraciton
x=40
the number is 40
Answer: 21
Step-by-step explanation:
Because u add 7 times 3 is 21
Answer: 225 square feet
Step-by-step explanation:
We find the area of the 4 triangle and the area of the rectangle and thereafter we add everything together.
Area of triangle 1 = 1/2 base × height
= 1/2 × 12 × 8
=96/2
=48
Area of triangle 2 = area of triangle 1= 48( because the opposite triangle are congruent so they have equal base and height)
Area of triangle 3 = 1/2×base×height
= 1/2 × 6 ×9.5
= 57/2
=28.5
Area of triangle 4=Area of triangle 3 = 57 (the opposite triangle are congruent and so they have the same base and height hence the same area)
Area of the rectangle = length×breadth
=12 × 6 =72
Total surface area = addition of all the areas of the triangles and the rectangle
Total surface area= 48+48+57+57+72 = 225
Therefore, the total surface area is 225 square feet
Answer:
y = -1|x+1| +1
Step-by-step explanation:
The vertex form of an absolute value equation is y = a* |x-h| +k
a = -1 because it opens downwards with a slope of ± 1. Next it's vertex is at (-1,1). So replace h with -1 and k with one.
y = -1|x+1|+1
Answer:
A tenth of a ham.
Step-by-step explanation:
1 Ham requires 10 people to make it and takes 1 month.
the population of the town is 100, so the quantity of ham we can produce is given by:
Acording to the last result, we can produce 10 hams per month.
if the total of people is 100, and the hams produced was 10, each people can consume:
