We will use the equation:
r t = 3/4 r ( t+12 ) /:r
t = 3/4 t + 9
t - 3/4 t = 9
1/4 t = 9
t = 9 * 4 = 36 minutes ( takes a trip to the market )
36 + 12 = 48 minutes
The ride home takes 48 minutes.
Answer:
54$
Step-by-step explanation:
If 6% per year for 3 years, we can do 6 x 3 = 18 to find the total interest percent over all the years. Then we can do 18% of 300 = 54 Therefore, you will gain 54$ of simple in three years.

Answer:
250%of4.4=look it up girl
Step-by-step explanation:
Step-by-step explanation:
density =mass/Volume
but Si unit of volume is m3
convert 980000cm3 into m3 by dividing with 1000000= 980000/1000000= 0.098 m3
D= M/V = 65.8/0.098= 671.43 kg/m3
Let the length be x and the width be y.
<u>The perimeter is 18 in.</u>
2 ( x + y ) = 18
x + y = 9
x = 9 - y ----------------------- (1)
<u>The area is 18 in²</u>
xy = 18
x = 18/y . ----------------------- (2)
<u>Sub (1) into (2):</u>
9 - y = 18/y
<u>Multiply by y on both sides:</u>
9y - y² = 18
y² - 9y + 18 = 0
(y - 3)(y - 6) = 0
y = 3 or y = 6
<u>When y = 6</u>
x = 9 - y = 9 - 6 = 3
<u>Find the Length and Width:</u>
Length = x = 6
Width = y = 3
Answer: The length is 6 inches and the width is 3 inches.
