(15(.17)+.29x)/(15+x)=.23
2.55+.29x=3.45+.23x
.06x=.9
x=15
So 15L of the 29% solution was added to the 15L of 17% solution to make
30L of 23% solution.
JK,KL and LJ are all to O.JA =14, AL=15, and CK=13. Find the perimeter of triangle JKL.? The answer is D. 84
answer:
30 yd^2
step-by-step explanation:
- in order to find the area of a triangle, we can use: A = 1/2 · b · h
- A = area
- b = base
- h = height
plug in,
A = 1/2(b)(h)
A = 1/2(15)(4)
A = 1/2(60)
A = 30 yd^2
We have been given that
2 cups flour + 3 eggs + 1 tbs oil → 4 waffles
In order to make 4 waffles we need 3 eggs.
Thus, to make 1 waffle we need 3/4 eggs.
Now, in 1 dozen there are 12 waffles. Hence, to make 12 waffles we need
Therefore, 9 eggs are needed to make 1 dozen waffles.
D is the correct option.
G(x) = 3x + 5
y = 3x + 5
3x = y - 5
x = (y - 5)/3
Therefore, g^-1(x) = (x - 5)/3
