eqaution 2:Proportinal
Step-by-step explanation:
Answer: 325$
Explanation:
Assume: A is the cost of washer
And B is the cost of dryer
A+B = 744
And: A = B + 94$
We get:
B + 94$ + B = 744
2B + 94 = 744
2B = 650
B = 325
Answer:
The first choice is the one you want
Step-by-step explanation:
Use geometric means to solve for a first. The formula is
and 64 = 15a and a = 64/15
That one was quite easy. Finding b is a bit more difficult.
The formula for finding b is

Solving for b:

Filling in we have
and
and
so b = 136/15
I am probably wrong but 45 degrees? Most if not all triangles equal 180. Since we already have 90 degrees we can subtract 90 from 180 and get 90. Both of the angles on the bottom left and right look about the same size so we can divide 90 by 2 and get 45.
Answer:
The total number of students in the gymnastics are <u>70</u>.
Step-by-step explanation:
Given:
Fifty-six students in a gymnastics club participated in the last fundraiser.
In the gymnastics club 80% of the students in the club participated in the fundraiser.
Now, to find the total number of students in the gymnastics.
Let the total number of students be 
Number of students participated in the club = 56.
Percent of students participated in the club = 80%.
According to question:



<em>Dividing both sides by 0.8 we get:</em>

Therefore, the total number of students in the gymnastics are 70.
