Answer: 15
Step-by-step explanation: 2 minus negative 1 is the same as 2+1. 2 plus 1 is 3 and 5 times 3 is 15. Therefore, 15 is your answer.
100%/x%=12/15
<span>(100/x)*x=(12/15)*x - </span>we multiply both sides of the equation by x
<span>100=0.8*x - </span>we divide both sides of the equation by (0.8) to get x
<span>100/0.8=x </span>
<span>125=x </span>
<span>x=125
so 125%</span>
Answer:350
Step-by-step explanation:
unknown is a
a% of 68=238
a/100 x 68=238
68a/100=238
Cross multiplying we get
68a=100x238
68a=23800
Divide both sides by 68
68a/68=23800/68
a=350
Answer:
Step-by-step explanation:
<u>Given:</u>
- Initial value is 45000.
- Reduction per day is 18%.
<u>The equation would be:</u>
, where C(t) is the number of candies left after t days
<u>Find the value of C(5):</u>
- C(5) = 45000*0.82⁵ ≈ 16683 rounded
The area of the parallelogram would be:
parallelogram area= length * width= 4*3=12
The area of the rectangle is count by multiplying the length and wide. In this picture, the length and wide is on diagonal line so you need to apply c^2= a^2+b^2 to find them.
length
length^2= a^2+b^2
length^2= 6^2+9^2
length^2= 117
length=√117
width
width^2= a^2+b^2
width^2= 2^2+3^2
width^2= 13
width= √13
rectangle area= length*width
rectangle area=√13*√117= √1521=39
Total area= 12+39= 51
