Angle A is 29 and Angle B is 61. It’s problem can be solved by written the equation X+X+32=90. This becomes 2X+32=90 subtract 32 from each side making 2X=58 divide by 2 X=29 and just plug x in to solve for both angle names.
Answer: (p x 6)+8.88= $9.78
Step-by-step explanation:
multiply 0.15 by 6
6 x 0.15= 0.90
add that to 8.88 and you get $9.78
hope this helps! ;P
Answer:
First brand = 18 gallons
Second brand = 12 gallons
Step-by-step explanation:
Let the first brand brand be A and the second brand be B.
Thus, since he wants to obtain 30 gallons of a mixture that contains 30% pure antifreeze, then we have;
A + B = 30 - - - (eq 1)
Also; The first brand is 20% pure antifreeze, and the second brand is 45% pure antifreeze. Thus;
0.2A + 0.45B = (0.3 × 30)
0.2A + 0.45B = 9 - - - (eq 2)
From eq 1, we have; A = 30 - B
Put 30 - B for A in eq 2;
0.2(30 - B) + 0.45B = 9
6 - 0.2B + 0.45B = 9
0.25B = 9 - 6
0.25B = 3
B = 3/0.25
B = 12
Thus, A = 30 - 12 = 18 gallons
Answer: 32 cups of milk
Step-by-step explanation:
The first thing to do is to convert the gallons of milk to milkshakes so that you are able to convert easier to cups.
There are 128 ounces in 1 gallon and Monica has 2 gallons. The amount of milk Monica has in ounces is:
= 128 * 2
= 256 ounces
Each cup is capable of holding 8 ounces and there are 256 ounces available so the number of cups of milk is:
= 256 / 8
= 32 cups of milk
