Answer:
19.95
Step-by-step explanation:
if you take 1.05 times it by 19 you get your answer
4/28 = 1/7 when dividing both numerator & denominator by 4 and this would be the simplified fraction.
You could use 1/7 to multiply with others to get other ratios that are equal to 4/28 or you could just use 4/28.
For example:
1/7 = 7/49
or
4/28 = 8/56
So the perimeter(P) of a rectangle would be:
P= 2L+2W
L being the length and W being the width.
The problem says the length is 4cm more than the width, so L= 4+W.
So if we substitute L with 4+W, we get:
P= 2(4+W) + 2W
Use the Distributive Property
P= 8+2W+2W
Combine like terms
P=8+4W
Since we're given the perimeter, we could replace P with 52. So:
52=8+4W
Subtract 8 to both sides
44=4W
Divide 4 to both sides
11=W
Therefore, the width is 11cm
And since the length is 4cm more than the width, we could add 4cm to 11cm to find that the length is 15cm
Thus, the dimensions of the rectangle are 15cm by 11cm
Answer:
Cost of 72 ounces of grapes is $13.5
Step-by-step explanation:
In order to solve his problem, we first need to get all the values in the same units.
1 pound = 16 ounces
∴ 6 pounds= 16×6 = 96 ounces
Now by unitary method, we solve the question as follows:
price of 96 ounces of grapes = $ 18
price of 1 ounce of grapes = $ (18÷96)
∴ price of 72 ounces of grapes = $ [(18÷96)×72]
= (0.1875×72) = $ 13.5
