Multiply the number in the tens place of the bottom
number by the number in ones place of the top number. So
multiply the 1 by the 5, which makes 5. Multiply the number in
the tens place of the bottom number by the number in tens
place of the top number. Multiply 1 by 2, which equals 2.
First, we'll set up two equations. One for the amount of each coin and another for the value of the coins.
N will represent nickels
D will represent dimes
N + D = 30
---The problem tells us that there are 30 total coins
0.05N + 0.10D = 2.95
---Nickels are worth 5 cents and dimes are worth 10 cents, and the total value of the coins is 2.95
Now that we have our equations, we need to solve for one of the variables in the first equation. I will solve for N.
N + D = 30
N = 30 - D
Then, we take that equation and substitute our new value for N into the second equation (value) and solve for D.
0.05(30 - D) + 0.10D = 2.95
1.5 - 0.05D + 0.10D = 2.95
1.5 + 0.05D = 2.95
0.05D = 1.45
D = 29
Now that we know how many dimes there are, we can plug that value into our equation for N and solve for N.
N = 30 - D
N = 30 - 29
N = 1
Therefore, there are 29 dimes and 1 nickel.
Hope this helps!
Volume of a sphere can be found by using the formula V=
where r is the radius of sphere.
Lianne drew a sphere with a radius of 7 in that is r= 7 in .she has written 
and need to find what should be multiplied in numerator with pi.
As r= 7 she needs to multiply numerator 
The number to be multiplied is 1372.
Answer:
$18.55
Step-by-step explanation:
I added the meal and drink then used a calculator and addded that total plus 7% of it then I added 20% of that to get 18.55
12.95+1.50 = x
x + 7% = y
y+ 20%
Answer:
Yes
Step-by-step explanation:
Because both triangles are equal in legnth.
