5/100 means that the 5 is in the hundredths place so the decimal is: .05
Answer:
8 teaspoons of sugar
Step-by-step explanation:
Make a proportion
You use 4 teaspoons of sugar for 5 teaspoons of creamer, and x teaspoons of sugar for 10 teaspoons of creamer
4/5=x/10
Cross multiply
5*x=4*10
5x=40
Divide both sides by 5 to isolate x
x=8
So, for 10 teaspoons of creamer, you will use 8 teaspoons of sugar
The total number of snowstorms is 60.
If 65% caused power outages, then the 21 storms that didn't represent 35% because 65%+35%=100%. You can set up a proportion (35/100=21/?) and use cross multiplication to find the total number of snowstorms. So, 21x100=2,100 and then 2,100 divided by 35 is 60.
Answer:
c. 4^3 * 5^2 (1600)
d. 9^4 * 7^2 (321489)
Step-by-step explanation:
Hi!
Remember that exponents are the number times itself (2*2 = 2^2).
So, in c, we have 4 times 4 times 4. We have 4 multiplied by 4 3 times. We can also write this as 4^3.
We also have 5 times 5. We can also write this as 5^2.
However, we need to multiply 5^2 by 4^3. So:
4^3 times 5^2 or 1600.
d.
Let's group the similar numbers together.
9 x 9 x 9 x 9 and 7 x 7
There are 4 9's, so 9^4.
There are 2 7's, so 7^2
Multiply the 2.
9^4 * 7^2
