One gallon equals to 4 quarts.
The instructions tell you to add 1 part of cleaner and 3 parts of water, in total 4 parts. It makes it easy as you can take that one part = one quart.
You will use 3 quarts of water and 1 quart of cleaner. The answer is D.
So you would draw an array and then subtract 1 from each side!
hope that helped
Answer:
The larger acute angle is equal to 50.8 degrees.
Step-by-step explanation:
Let's solve for both of the acute angles for the purpose of checking our work at the end with angle A being the top angle and angle B being the one on the base of the triangle (that's not the 90 degrees one). Determining whether to use sin/cos/tan comes from SOH-CAH-TOA.
A = cos^-1 (2√6/2√15)
However, you need to move the radical out of the denominator by multiplying √15 to the numerator and denominator. You should come up with (2√90)/30. So,
A = cos^-1 (2√90/30) = 50.768 degrees.
B = sin^-1 (2√90/30) = 39.231 degrees.
Now, we can check the work by adding the 2 angles to 90 and, if it comes to 180, it's right.
cos^-1 (2√90/30) + sin^-1 (2√90/30) + 90 = 180.

Okay first you need to combine like terms together (3x and 1x)
7x + 4 = 5 + 4x
now you need x only on one side, you could subtract either 7x or 4x
3x + 4 = 5
subtract 4 over
3x = 1 is the answer
Option is B) y-3x=0 represents a proportional relationship between the x and y values
Explanation:
Case 1 = y+4=3x
From the above equation we can see that if we change the value of x, the value of y does not changes by proportionality due to the presence of 4 .
Case 2: y-3x=0
From the above equation we can see that if we change the value of x, the value of y changes by proportionality.
Hence the correct option is B.
Case 3 = y+5x=6
From the above equation we can see that if we change the value of x, the value of y does not changes by proportionality due to the presence of 6.
Case 4 = y+1/4×x=2
From the above equation we can see that if we change the value of x, the value of y does not changes by proportionality due to the presence of 2.
