Answer:
1 mile/hour is equivalent to 1.47 feet/seconds
Step-by-step explanation:
Given
Required
Determine the equivalent of 1 mile/hour
Express 60 as 60 * 1
Divide both sides by 60
Reorder
Divide 88 by 60
Approximate to 3 significant figures
Hence;
1 mile/hour is equivalent to 1.47 feet/seconds
Answer:
Look at the number line.
Step-by-step explanation:
Step 1: Draw a number line.
Step 2: Mark -4 on the number line.
Step 3: Here we have to subtract 8, therefore, from -4 move 8 units left, we end up at -12.
That is the answer. Here is the picture.
Hope this will help you.

Answer:
$9000 at 4$
and
$10000 at 8%
Step-by-step explanation:
Let's assume that "x" is the amount deposited in the 4% account and "y" is the amount deposited in the 8% account.
Recall the formula for interest as :
where I is the interest, R is the annual rate of interest and t is the number of years.
Since there are two investments, we need to add both interests at the end of the one year: I1 = x (0.04) (1) = 0.04 x and I2 = y (0.08) (1) = 0.08 y
Total Interest = Interest (from the 4% account) + Interest (from the 8% account)
Total Interest = $1160 = 0.04 x + 0.08 y
we also know that the total invested (x + y) adds to $19,000, that is:
$19,000 = x + y
Then we can solve these system of two equations by substitution, for example solving for y in the second equation and using the y substitution in the first equation;
y = 19000 - x
1160 = 0.04 x + 0.08 (19000 - x)
1160 = 0.04 x + 1520 - 0.08 x
0.08 x - 0.04 x = 1520 - 1160
0.04 x = 360
x = 360/0.04 = $9000
Then the other investment was : y = $19000 - $9000 = $10000
