Answer:
25
Step-by-step explanation:
If 5/8 are boys then
1 - 5/8 = girls
3/8 = girls
3/8 of the total are girls
Let x = total
3/8 ( x) = 15
8/3 * 3/8 * x = 15 * 8/3
x = 40
There are 40 total students
5/8 are boys
5/8 * 40
25 are boys
This problem can be solved by writing a conditional equation.
(8*1.5)+6= d
12+6= d
d= 18GB
Check- 18-12= 6GB
Answer:
A) the y-intercept of g(x) is less than the y-intercept of f(x).
Answer:
Step-by-step explanation:
The pythagorean theorem goes: a^2 + b^2 = c^2
c is the hypotenuse of the right triangle, the longest side.
This means that by squaring the two shorter sides of an answer choice and seeing if they are equal to the longest side squared we can see if that answer choice contains the sides of a right triangle.
So, for example, lets look at answer choice B. 4.5^2 + 3^2 = 29.25 and 7.5^ = 56.25
29.25 is not equal to 56.25 so B is incorrect.
Doing the same process with answer choice A gets us: 6^2 + 2.5^2 = 42.25 and 6.5^2 = 42.25
This means a^2 + b^2 equals c^2 and answer choice A is our correct answer.
