Answer:

See the explanation.

Step-by-step explanation:

Given number, factorization and exponent. We need to fill the table.

$For\ 49\\\\Factorization=7\times7\\Exponent=7^2\\\\For\ 3\times3\times3\\\\Number=27\\Exponent=3^3\\\\For\ 8^3\\\\Number=512\\Factorization=8\times8\times8$

See $49$ when factored it will give us $7\times7$ . Also, the exponent will be $7^2$

And when we multiply $3\times3\times3$ we get $27$ so the number will be $27$ . Also, the exponent will be $3^3$ .

Similarly when we simplify $8^3$ it will get factor form $8\times8\times8$ and the number will be $512$ .

Light bulbs usually cost 2$. They are on sale for 0.50 of the regular price. What is the sale price? Is this a better price than

Vinil7 [7]

Answer:

The sale price is $1

$1 is not a better price since there is a cheaper price of $0.7

Step-by-step explanation:

Original price is $2

The price now is 0.5 × $2 = $1

If the sale price was 0.35 of the original price;

It would be 0.35 × $2 = $0.7

$1 is not a better price since there is a cheaper price of $0.7

There are some goats, cows and, sheep. 2/5 of the animals were goats. There were three times as many sheep than cows. If there w

kobusy [5.1K]

Answer:

81 sheep were there on the farm

Step-by-step explanation:

Consider the provided information.

Let x represents the number of goats.

y represents the number of cows.

z represents the number of sheep.

Therefore, the total number of animals are x+y+z

2/5 of the animals were goats. This can be written as:

$\frac{2}{5}(x+y+z)=x$

There were three times as many sheep than cows.

$z=3y$

There were 45 more goats than cows,

$x=45+y$

Substitute the value of x and z in equation 1.

$\frac{2}{5}(45+y+y+3y)=45+y$

$\frac{2}{5}(45+5y)=45+y$

$2(9+y)=45+y$

$18+2y=45+y$

$y=27$

Hence, there are 27 cows.

Substitute the value of y in $x=45+y$

$x=45+27$

$x=72$

Therefore, there are 72 goats.

Substitute the value of y in $z=3y$

$z=3(27)$

$z=81$

Thus, there are 81 sheep.

Hi there
The formula of the future value of annuity ordinary is
Fv=pmt [(1+r/k)^(kn)-1)÷(r/k)]
Fv future value?
PMT monthly payment 608
R interest rate 0.06
K compounded monthly 12
N time 6years
So
Fv=608×(((1+0.06÷12)^(12×6)
−1)÷(0.06÷12))
=52,536.58...answer

Good luck!

Murljashka [212]

Answer:

a= -36

Step-by-step explanation:

1. Subtract 2 from both sides

2 + a/6 -2 = -4 -2

2. Simplify

a/6 = -6

3. Multiply both sides by 6

6a/6 = 6(-6)

4. Simplify

a = -36
