The expression in the form [tex]7^n[/tex]
[tex]7^2\times \:\:7^6=7^n[/tex]
Step-by-step explanation:
[tex]7^2\:\times \:7^6[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\times \:a^c=a^{b+c}[/tex]
[tex]7^2\times \:7^6=7^{2+6}[/tex]
So the expression becomes
[tex]7^2\:\times \:7^6=7^{2+6}[/tex]
[tex]=7^{2+6}[/tex]
Add the numbers: 2+6=8
[tex]=7^8[/tex]
Therefore, the expression in the form [tex]7^n[/tex]
[tex]7^2\times \:\:7^6=7^8[/tex]

n − 2/3 = 25 3/4 help now
Answer:
26 5/12
Step-by-step explanation:
n − 2/3 = 25 3/4 Add 2/3 to both sides
n - 2/3 + 2/3 = 25 3/4 + 2/3 Combine
n = 25 3/4 + 2/3
Work with the fractions
3/4 + 2/3 The lowest common denominator is 12
(3*3)/(3*4) = 9 / 12
(2*4)/(3*4) = 8/ 12
9/12 + 8/12 = 17/12 = 1 5/12
Now you need to add 1 to 25
1 + 25 = 26
And add the fraction 5/12
The answer is 26 5/12

Answer:
32%
Step-by-step explanation:
136/200 broke. We want to know how many eggs out of 100 broke, so we need to set up an equivalent proportion.
136/200=x/100
Cross multiply.
13600=200x
Divide both sides by 200.
68=x
Since 68 percent broke, that means the other 32 percent survived.

The deli in front of the school sells 36 cheese sandwiches a day, which was 40% of the total number of sandwiches sold that day. What was the total number of sandwiches sold that day?
Answer:
The total number of sandwiches sold that day was 90.
Step-by-step explanation:
Given that the 36 cheese sandwiches sold represent 40% of the total sandwiches sold on that day, to obtain the total number of sandwiches sold the following calculation must be made:
40 = 36
100 = X
((100 x 36) / 40) = X
3600/40 = X
90 = X
Therefore, the total number of sandwiches sold that day was 90.

Write the expanded form 0.45 in this way using fractions and using decimals
Answer:
0.4 + 0.05= 0.45
FRACTION FORM:
4/10+ 5/100= 0.45
Step-by-step explanation:
Hope this helps!! Tell me if I'm wrong! :)
Using fractions, 0.45 can be written as [tex]\frac{3}{10}[/tex] + [tex]\frac{3}{20}[/tex]. Using decimals, 0.45 can be written in the form as 0.30 + 0.15.
What is Decimal Numbers?Decimal number system is applicable for both integers as well as non integers. Decimal number include a whole number part and a decimal part separated using decimal point.
Fractions are the numbers which are part of a whole.
All decimal numbers can be written as fractions and fractions can be written in the form of decimal numbers.
The given number is 0.45.
0.45 can be written as [tex]\frac{45}{100}[/tex].
[tex]\frac{45}{100}[/tex] can be expanded in various ways like (40 + 5)/100, (42 + 3)/100 and so on.
[tex]\frac{45}{100}[/tex] can be written in one of the form as [tex]\frac{30}{100}[/tex] + [tex]\frac{15}{100}[/tex].
When simplified, [tex]\frac{30}{100}[/tex] simplified to [tex]\frac{3}{10}[/tex] and [tex]\frac{15}{100}[/tex] simplified to [tex]\frac{3}{20}[/tex].
So 0.45 = [tex]\frac{3}{10}[/tex] + [tex]\frac{3}{20}[/tex].
Now, in the decimal form, [tex]\frac{3}{10}[/tex] = 0.3 and [tex]\frac{3}{20}[/tex] = 0.15
So, 0.45 = 0.3 + 0.15
Hence 0.45 can be expanded in the fractional form as [tex]\frac{3}{10}[/tex] + [tex]\frac{3}{20}[/tex] and in the decimal form as 0.3 + 0.15.

The length of a rectangle is three times its width the length is 3 3/4 feet. What is the area if the rectangle?
Answer:
A = 4 11/16 or 4.6875
Step-by-step explanation:
3 3/4 = 3W
divide both sides by 3
15/4 divided by 3 = W
15/4 x 1/3 = W
5/4 = W
A = L x W
3 3/4 x 1 1/4 = 15/4 x 5/4 = 75/16 = 4 11/16

Step-by-step explanation:
A customer requires a car service for 80 miles,
How much money will the customer save by taking Sal's Car Rides instead of Ray's Limo? Enter the answer in the box.
Answer:
$25
Step-by-step explanation:
Derive an equation to represent the cost of using each ride.
Sal's Car Rides:
Using 2 pairs of values from the table, (0, 40) and (20, 80), find the slope, m (fee per mile).
[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{80 - 40}{20 - 0} = \frac{40}{20} = 2 [/tex]
The y-intercept, b, is the one-time fee for fuel. This is the value of the cost ($) when number of miles traveled is 0.
Thus, b = 40.
Substitute m = 2, and b = 40 into [tex] y = mx + b [/tex].
Equation for the total cost for Sal's Car Rides would be:
[tex] y = 2x + 40 [/tex].
Find the total cost to be charged if a customer requires the a car service for 80 miles if he chooses Sal's Car Rides.
Simply substitute x = 80 in [tex] y = 2x + 40 [/tex].
[tex] y = 2(80) + 40 = 200 [/tex]
The customer would pay $200.
Ray's Limo:
The equation that represents the total cost (y) to be charged for number of miles (x), given that $2.50 is charged per mile plus a one-time fee of $25 for fuel, would be:
[tex] y = 2.5x + 25 [/tex].
If a customer uses Ray's Limo services for 80 miles, the cost charged would be:
Substitute x = 80 in [tex] y = 2.5x + 25 [/tex].
Thus:
[tex] y = 2.5(80) + 25 = 225 [/tex].
The fee the customer would pay = $225 for using Ray's Limo services.
Therefore, if the customer takes Sal's Car Rides instead of Ray's Limo, he would save, $225 - $200 = $25.
The customer would save $25.

An arcade holds a game night. Of the 120 customers who visit during the game night, 30 customers are offered free games. What percent of the customers are not offered free games?
Answer:
75% of customers are not offered free games.
The percent value of the customers who are offered free games are 25%.
What is percentage?A percentage is a value that indicates 100th part of any quantity. A percentage can be converted into a fraction or a decimal by dividing it by 100. It can be applied to find the simple and compound interest.
The total number of customers are given as 120.
And, the customers who are offered free games are 30.
