Answer:
12^4 = 20736
Step-by-step explanation:
The property of exponents used to simplify : 12^8/12^4
The division property :
a^x / a^y = a^(x - y)
Therefore ;
12^8/12^4
12^8 / 12^4 = 12^(8 - 4) = 12^4 = 20,736
Help I dont understand the Problem

You and a friend are trying to fill your pools with water. Your pool originally had 10 gallons of water, and the hose is filling it at rate of 2 gallons per minute . Your friends pool originally had 4 gallons of water in the pool, and their hose is filling the pool at a rate of 3 gallons per minute create a system of equations using the information from the problem
Answer:
y = 2x + 10
y = 3x + 4
Step-by-step explanation:
2x + 10 = 3x + 4
10 = x + 4
x = 6
I don’t get this can someone explain please
Answer:
2^4/4^2 will be 1, I will explain after answering,
2 x 3^1 = 6
(4 - 2) ^2 = 4
First. Evaluate the exponents in the fraction above
2 x 2 x 2 x 2 = 16
4 x 4 = 16
and 16 over 16 would equal 1 whole
3 to the power of 1 means just 3 so 2 x 3 = 6 (easy multiplication)
Evaluate in the parenthesis first: 4 - 2 = 2 then 2 to the power of 2 would be 2 x 2 = 4

In the diagram, △ABC∼△CDE. Write an equation for line k
Answer:
Step-by-step explanation:
Line AB is parallel to line CD (k) so they have the same slope.
slope=m=(y2-y1)/(x2-x1)
m=(6-0)/(4-0)
m=6/4=1.5
y=mx+b, we know m=1.5 so
y=1.5x+b, and we know it passes through point (4,0) so we can solve for b
0=1.5(4)+b
0=6+b
b=-6 so line k is
y=1.5x-6
please help mee , i will marl the brainliest .
Answer:
n = - 6
Step-by-step explanation:
Given k(x) then k(x) + n is a vertical translation of k(x)
• If n > 0 then a shift up of n units
• If n < 0 then a shift down of n units
Here k(x) has been shifted from (0, 0 ) to (0, - 6 )
That is a shift down of 6 units, then
p(x) = k(x) - 6
That is n = - 6
What is the area of the rhombus (figure only show one part of the diagonals)
Answer:
60 cm^2 (dark blue)
Step-by-step explanation:
Since a rhombus's diagonal bisect each other, the diagonal's full length is 10 and 12. From there the area is 10*12 / 2 which is 60

Step-by-step explanation:
Great ran a one mile race in 5 minutes. Inex ran a quarter mile in 1 minute and 20 seconds.
If Inez ran the mile at her quarter mile pace of 1 minute and 20 seconds, how fast would she run the mile? Write your answer in minutes and seconds. (There are 4 quarter miles in a one mile race). 1._______)
2. Which of the two runners had the fastest time? ______
3. How much faster was her mile in seconds? _______
Answer:
1. The time it would take Inex to run 1 mile is 5 minutes 20 seconds
2. Great has the fastest (lowest) time
3. When running a mile Great is faster than Inex by 20 seconds
Step-by-step explanation:
1. The distance Great ran in 5 minutes = 1 mile
The distance Inex ran in 1 minute and 20 seconds = A quarte mile = (1/4) mile
We note that 1 minute and 20 seconds = 4/3 minutes
Given that the time Inex ran 1/4 mile = 4/3 minutes...(1)
We have;
The time it would take Inex to run 1 mile is given as follows;
1 = (1/4) ÷ (1/4)
1 mile = ((1/4) ÷ (1/4)) mile = (1/4) mile/(1/4)
The time to run 1 mile = The time to run (1/4) mile/(1/4) = 4/3 minutes/(1/4) (by dividing both sides of equation (1) by (1/4),
4/3 minutes/(1/4) = 4 × 4/3 minutes = 16/3 minutes = [tex]5\frac{1}{3}[/tex] minutes= 5 minutes 20 seconds
The time it would take Inex to run 1 mile = 5 minutes 20 seconds
2. Given that Great ran a one mile race in 5 minutes, and Inex ran the same one mile race in 1 minute and 20 seconds, Great has the fastest (lowest) time
3. The amount faster Great's time is faster than Inex's time to run one mile = 5 minute 20 seconds - 5 minutes = 20 seconds.
David y Angie tienen dos cartulinas iguales. David corta la suya en 3 trozos iguales y Angie la corta en 7 trozos. Los dos usan 2 de sus trozos para hacer un muñeco. Que fracción de cartulina ha usado David?¿Y Angie?¿Quien ha usado mas cartulina? Alguien me lo dice por fa es que no lo entiendo
Answer:
(i) David ha empleado [tex]\frac{2}{3}[/tex] de la cartulina.
(ii) Angie ha empleado [tex]\frac{2}{7}[/tex] de la cartulina.
(iii) David ha usado más cartulina.
Step-by-step explanation:
El problema indica que David y Angie emplean una cartulina del mismo tamaño cada uno. David corta la suya en 3 pedazos iguales, mientras que Angie obtiene 7 pedazos iguales. Finalmente, cada uno emplea dos de sus pedazos. A continuación, respondemos a las preguntas del enunciado:
(i) ¿Qué fracción de cartulina ha usado David?
La fracción de cartulina empleada por David es igual a los pedazos utilizados divididos por el total de pedazos. Esto es:
[tex]x = \frac{2}{3}[/tex]
David ha empleado [tex]\frac{2}{3}[/tex] de la cartulina.
(ii) ¿Qué fracción de cartulina ha usado Angie?
Aplicando el mismo procedimiento del punto anterior, tenemos que:
[tex]x = \frac{2}{7}[/tex]
Angie ha empleado [tex]\frac{2}{7}[/tex] de la cartulina.
(iii) ¿Quién ha usado más cartulina?
La persona que ha usado la mayor cantidad de cartulina es aquella que tiene el menor denominador. Por tanto, David ha usado más cartulina.

B: d+70=t
C: t=70d
D: t+70=d
Answer/Step-by-step explanation:
D = distance
T = Time
You are trying to find the Time so,
T = ???
T = 70 ?
So you are driving PER hour so --> multiply
T = 70d

Taylor has $20 to spend on school supplies. A pack of
colored pencils is $2.75. Taylor writes the inequality
2.75p < 20, where p is the number of packs of colored
pencils, taldetermine how many packs she can buy.
How many packs can she buy?
Answer:
7 packs
Step-by-step explanation:
2.75p < 20
Divide both sides by 2.75
2.75p/2.75 < 20/2.76
Simplify
p = 7.27 (27 repeating)
Round
p = 7
