Answer:

The answer is ten or Letter C

Step-by-step explanation:

You plug in the values of w and x so you get 3(1/4*8)+4. Multiply whats in the parthensis then distribute the 3 into 2 and get 6. So 6+4=10. Thats the answer for this expression. I hope this helps!

Raphael paid $ 160$160 for a camera during a 75 %75% off sale. What was the camera's regular price?

Kay [80]

So paid160

75 percent off
100 percent=original
75 percent off=100-75=25%
160=25% of original cost
'of' means multiply
remember tha tpercent is parts out of 100 so
25%=25/100=1/4
160=1/4 times original cost
multily both sides by 4
640=original cost
answe ris $640 =original cost

HELP!!! Monica measures the number of bacteria that are living on her petri dish. Each day, she measures the amount of change in

SSSSS [86.1K]

Answer:

The correct option is;

C) 6554

Step-by-step explanation:

The given data are;

Day, Amount of change in Bacteria

1, 2

2, -8

3, 32

4, -128

Given that the data follows a geometric sequence, we have;

The first term of the series = 2, the common ratio = -4, the sum of a geometric progression is given by the following formula;

$S_n = \dfrac{a \times \left (r^n - 1\right )}{r - 1}$

Which gives;

$S_7 = \dfrac{2 \times \left ((-4)^7 - 1\right )}{(-4) - 1} = \dfrac{2 \times \left (-16384- 1\right )}{-4 - 1} = \dfrac{2 \times \left (-16385\right )}{-5} = 6554$

Therefore, the correct option is C) 6554.

Find the GCF of the following numbers:

Maurinko [17]

Answer:

$2^53^5$

Step-by-step explanation:

So if we compare $2^5 \cdot 3^7$ to $2^7 \cdot 3^5$ , we should see the most amount of factors of 2 that they have in common is 5 and the most amount of factors of 3 that they have in common is 5.

If you aren't sure on the number of factors of 2 and 3 they have in common you could write it all out:

$2^53^7=(2)(2)(2)(2)(2)\cdot\text{ }(3)(3)(3)(3)(3)(3)(3$

$2^73^5=(2)(2)(2)(2)(2)(2)(2)\text{ }(3)(3)(3)(3)(3)$

So if I were able to circle each pair of 2's they had in common I would circle 5 pairs.

If were able to circle each pair of 3's they had in common I would circle 5 pairs.
