1 gallon cost $15
1 quarts cost $4
1 quarts = 1/4 gallon
15x for number of gallon cans
2 cans at $4 each = $8
15x + 8 = 53
Subtract 8 from both sides:
15x = 53-8
15x = 45
Divide both sides by 15:
x = 45/15
x = 3
She bought 3 gallon cans of paint
Plus she bought 2 quart cans, which is equal to a half gallon.
She bought a total of 3.5 gallons of paint.
0.0239 x 28 = .6692 (this is the amount of tax paid)
shoes + tax = total
$28 + 0.6692 = $28.6692 which rounds to $28.67 (money is always rounded to the hundredths place)
Answer:
QV = 36 UNITS
Step-by-step explanation:
Centroid of a triangle divides the median in the ratio 2 : 1.
QU is the median and V is Centroid. Therefore,
QV : VU = 2 : 1
Let QV = 2x & VU = x
QV + VU = QU
2x + x = 54
3x = 54
x = 54/3
x = 18
QV = 2x = 2*18 = 36
Answer:
Option C
Step-by-step explanation:
By the property of a rectangle,
"All interior angles of a rectangle measure 90°"
Therefore, m∠ABC = 90°
By applying cosine rule in the right triangle ABC,
cos(∠CAB) = 
cos(25°) = 
AC = 
AC = 
AC = 19.86
Therefore, Option C will be the answer.
