Rewrite the expression in the form 7^n
7^2 x 7^6
Answer:
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]

Collins Middle School has 240 sixth grade students. If the sixth grade is 30% of the total school, how many students are in the middle school?
270
210
72
800
BRAINLIST, EXTRA POINTS,FIVE STARS, AND A HEART
PLEASE HELP!
Answer:
800
Step-by-step explanation:
We can set up a proportion using the information we are given. We know that 240 students corresponds to 30% and that the total number of students, x, corresponds to 100%
[tex]\frac{240}{x} = \frac{30}{100}[/tex]
Cross multiply and solve:
240 * 100 = 30x
24000 = 30x
800 = x

Answer:
The population decreases by 140 in the next year.

HELP HELP MEEEEEEE Determine whether the triangles are similar. If they are write similarity statement. Explain your reasoning.
Answer:
no
Step-by-step explanation:
every triangles degrees equal 180.
78+21=99

the smaller triangle
21+80= 101
180-101=79
so the degrees are different

Write the following linear equation in function notation y=7x-2
Answer:
The function notation is when we represent one of the coordinate points as a function of the other ones.
In the general case, we will have:
y = f(x)
Now, we have that:
y = 7*x - 2
Then the function notation will be:
y = f(x) = 7*x - 2
or simply
f(x) = 7*x - 2
Answer:
f(x)= 7x-2
Step-by-step explanation:
I did the quiz and got it right.

The circumference of a circle is 15π centimeters. What is the area of the circle in terms of π?
Answer: 7.5²π square centimeters. OR 56.25π cm²
Step-by-step explanation:
Circumference = diameter × π
So the diameter is 15 cm
Area = πr²
Radius is half the diameter, so 15/2 or 7.5
Area = (15/2)²π cm²

In the first ten months of the year, people took out 427,113 books from the Brookton Library. The librarian would like to set a new record and have 500,000 books go out in one year. If 38,264 books are taken out in November, how many must go out in December to meet the librarian's goal?
Answer:72,887
Step-by-step explanation: 500,000 - 427,113 = 72,887
Answer:
34,623 books
Step-by-step explanation:
First, add the amount taken out in November to the amount from the first 10 months of the year.
427,113 + 38,264
= 465,377
Then, subtract this from 500,000:
500,000 - 465,377
= 34,623
So, to meet the librarian's goal, 34,623 books need to go out in December.
What is the missing x-coordinate for a line that has a slope of -2 and goes through the points (5, 1) and (x, -3)
Answer:
X=7
Step-by-step explanation:
we already know the slope is -2, so y=-2x+m
since the line goes through point (5,1)
1=(-2)x5+m
1=m-10
m=11
the equation should be y=-2x+11
-3=2x+11
-14=2x
x=7
