Answer:
7^22
Step-by-step explanation
Given the expression
7^8 × 7^3 × 7^4 × 7^7
In indices
a^m × a^n = a^{m+n}
The powers are added since the base are the same
We ate going to add all the powers of the expression given since they have the same base which is 7
7^8 × 7^3 × 7^4 × 7^7
= 7^{8+3+4+7}
= 7^22
= 3.91×10^18
Answer:
4.1kg
Step-by-step explanation:
A recipe requires 5 kg of cleaned, peeled, and diced cucumbers. What is the minimum amount of cucumbers to purchase if the yield percent is 82?

Answer:
Find out the what is the price of oranges this week .
To prove
As given
last week the price of oranges at the farmers market was $1.75 per pound.
This week a price has decreased by 20% .
20% is written in the decimal form

= 0.20
Decreased in the price = 0.20 × 1.75
= $0.35
The price of oranges this week = Price of orange at last week - Decreased in the price
= $1.75 - $0.35
= $ 1.4
Therefore the price of oranges this week is $1.4 .
Answer:
The answer to this question would be (to my best guess), 36 hours.
Step-by-step explanation:
First
You have to find the ratio between 87.5% and 100%. This is because you want to find what 100% represents.
To do this, you have to divide 100 by 87.5, which would represent 100 divided by 87.5. This will equal 1.142857142857143 , which isnt an easy number to work with.
Lastly
You have to multiply 1.142857142857143 by 31.5, because you reverse the previous operation, but the only difference is you swap out the percentages with the numbers they represent. This equals the final answer, which is 36, representing 36 hours.
Answer:
-6.20x-6.20y=-948.6
add this to equation 2
6.20x-6.20x +9.30y-6.20y=1125.30-948.60
3.10y= 176.70
/3.10
y=176.70/3.10
y = 57 number of adult tickets
153-57=96 child tickets
Step-by-step explanation:
child admission is $6.20 : x numbers
adult admission is $9.30 : y numbers
153 tickets were sold
sales of $1125.30 .
x+y = 153.........................1
6.20x+9.30y= 1125.30..............2
