Answer:
$3.49
12 quarters,4 dimes,1 nickle, 4 pennies
Step-by-step explanation:
First remember that;
Quarter=25 pennies
Dime=10 pennies
Nickel =4 pennies
I cent =0.01$
Given the amount as $3.50
Assume you use 4 quarters, this means a whole dollar, so it will be;
1 dollar = 4quarters
3 dollars=?
cross multiply
3×4=12 quarters
The remaining $0.49
Here identify 40 cents, which is 40 pennies
But 10 pennies=1 dime
so 40 pennies=?
cross-multiply
(40×1)÷10=4 dimes
and a nickel for 4 pennies.
Answer:
a.
b.
Step-by-step explanation:
Given
A(-8,7) and B(6,-9).
Solving (a):
Determine the Midpoint M;
This is calculated as follows;
Where
Substitute these values in the formula
<em>Hence; the midpoint is (-1,-1)</em>
Solving (a):
Here, we have
C = (2,7)
M; Midpoint = (-1,-1)
Required: Determine D
This is calculated as follows;
Where
Substitute these values in the formula
Solving for x2
Multiply both sides by 2
Subtract 2 from both sides
Solving for y2
Multiply both sides by 2
Subtract 7 from both sides
Hence, the coordinates of D is

Answer:
Y=t+5
Step-by-step explanation:
Bob starts running...(1)
Bill starts running 5 seconds later...(2)
From (1) and (2) we know that Bob had been running for 5 seconds when Bill started running.
The expression we are looking for is
Y=t+5
Y is the number of seconds Bob has been running
t is the number of seconds Bill has been running
