Answer:
60% decrease
Step-by-step explanation:
To find the percentage increase/ decrease construct a fraction with numerator showing increase/ decrease and denominator with original number then multiply the fraction by 100%
here the decrease = 45 - 18 = 27
percent decrease = 
× 100%
= 
× 100% = 60%
Answer:
the two numbers are 151 and 66
Step-by-step explanation:
x+y =217
x-y = 85
add the two equations
x+y =217
x-y = 85
-------------
2x = 302
divide by 2
2x/2 = 302/2
x = 151
now find y
x+y =217
151+y =217
subtract 151 from each side
y = 217-151
y =66
Answer: 300.
Step-by-step explanation: 225/(No denominator) = 75/100.
225 doesn't go in 75. So, 75/100 divided by 5 = 15/20.
I want to find what number you multiply from 15/20 to get 225/(No
denominator). So, I divide 225 by 15. = 15, so multiply 15 x 15 = 225, and
the denominator, 20 x 15= 300.
(Sorry if you don't understand, I don't really know how to explain things.)
But here's your answer!
Calculate the lengths of the sides of the triangle:
The triangle has three different sides, so it's a scalene triangle.
Now if c is the longest side of the triangle, and a and b are the shorter sides, then:
- if , the triangle is right
- if , the triangle is acute
- if , the triangle is obtuse
The longest side is 5.
The square of the longest side is equal to the sum of the squares of the shorter sides, so it's a right triangle.
The triangle is a right scalene triangle.
Move the decimal places, the answer is 6.7 x 10^6
