Answer:

(-3+5)(1)=-3+5

Step-by-step explanation:

The multiplicative identity is 1.

The multiplicative identity property days that, if you multiply a real number by 1, that result is the same real number.

This is demonstrated in option B of the given alternatives, where we have:

[tex]( - 3 + 5)(1) = - 3 + 5[/tex]

The multiplication by did not change b the value.

Answer:

60.

Step-by-step explanation:

(x^2 - 25) / (√(x + 4) - 3).

We rationalise the expression by multiplying top and bottom of the fraction by the complement of the denominator.

That is by (√(x + 4) + 3):

       (x^2 - 25)(√(x + 4) + 3)

=   ------------------------------------

     (√(x + 4) - 3)(√(x + 4) + 3)

=   (x + 5)(x - 5)(√(x + 4) + 3)

    ----------------------------------

                (x - 5)

= (x + 5)(√(x + 4) + 3).

The limit as this---> 5

is  (5 + 5)(√(5 + 4) + 3)

= 10 * 6

= 60.

The amount when she is 35 is $8,733.01221.

Given that,

Based on the above information, the calculation is as follows:

[tex]= \$4,000 \times (1 + 9.8\%\div 12)^{8\times 12}\\\\= \$4,000 \times (12.098\div 12)^{96}[/tex]

= $8,733.01221

Therefore we can conclude that The amount when she is 35 is $8,733.01221.

Final answer:

At age 35, Jill's IRA investment, which started with a $4,000 deposit at age 27 and earns 9.8% interest compounded monthly, will be worth approximately $8,159.55.

Explanation:

To determine the future value of Jill's IRA investment, we will use the formula for compound interest, which is A = [tex]P(1 + \(\frac{r}{n}\))^n^t[/tex], where:

P is the principal amount (the initial amount of money)

r is the annual interest rate (decimal)

n is the number of times that interest is compounded per year

t is the time the money is invested for in years

A is the amount of money accumulated after n years, including interest.

In Jill's case, she deposited $4,000 into an IRA at age 27, and we want to find out what it will be worth when she is 35. The annual interest rate is 9.8%, but since it is compounded monthly, we will have to convert this to a monthly rate and adjust the time accordingly

The steps to solve for the amount A are as follows:

Convert the annual interest rate to a decimal: 9.8% = 0.098

Find the monthly interest rate by dividing the annual rate by 12: \[tex](\frac{0.098}{12}\)[/tex]

Calculate the number of years money is invested: 35 - 27 = 8 years

Find the number of times interest is compounded: 12 months/year ×  8 years

Use the compound interest formula to calculate A.

Now, let's do the math:

P = $4,000

r = 0.098 / 12

n = 12

t = 8

A = 4000(1 + [tex]\(\frac{0.098}{12}\))^(12\(\times\)8)[/tex]

Using a calculator we get:

A = $4000(1 + 0.0081667)⁹⁶

A = $4000(1.0081667)⁹⁶

A = $4000 [tex]\(\times\)[/tex] 2.0398873

A ≈ $8,159.55

Therefore, at age 35, Jill's IRA investment will be worth approximately $8,159.55.

Answer:

v = 1620 ^3

Step-by-step explanation:

If the area of the bottom is 180 sq in and the height is 9 in then this is how you would solve the problem.

To get area of the volume is l * w * h

Because of the associative property we can do this in any order we want

If we know that l * w is 180, then all we have to do is multiply 180 by 9

180 * 9 = 1620

Answer:

Part 1) The volume of the storage body is 576 cubic feet

Part 2) To find out how many boxes can she fit in the storage body, divide the volume of the storage body by the volume of each box

Part 3) Sheila can fit 64 boxes into the truck

Step-by-step explanation:

step 1

Find the volume of the storage body

we know that

The volume of the of the storage body is equal to the volume of two rectangular prism

The volume of a rectangular prism is equal to

[tex]V=LWH[/tex]

First rectangular prism (top)

[tex]V=(15)(6)(8-6)=180\ ft^3[/tex]

Second rectangular prism (bottom)

[tex]V=(15-4)(6)(6)=396\ ft^3[/tex]

The volume of the storage body is

[tex]V=180+396=576\ ft^3[/tex]

step 2

we know that

To find out how many boxes can she fit in the storage body, divide the volume of the storage body by the volume of each box

step 3

substitute the given values

[tex]\frac{576}{9}= 64\ boxes[/tex]

therefore

Sheila can fit 64 boxes into the truck

Answer:

length = x - 2

Step-by-step explanation:

The area (A) of a rectangle is calculated as

A = length × width

Here A = x² - 7x + 10 and width = x - 5

x² - 7x + 10 = length × (x - 5) ← divide both sides by (x - 5)

length = [tex]\frac{x^2-7x+10}{x-5}[/tex] ← factor the numerator

           = [tex]\frac{(x-5)(x-2)}{x-5}[/tex] ← cancel common factor (x - 5) on numerator/ denominator

           = x - 2

Thus length = x - 2 metres

[tex]9x +30\geq 30[/tex]

Solution:

Given that,

Translate the sentence into an inequality

The sum of a number times 9 and 30 is at least - 15

Let "c" be the unknown variable

"at least" means "greater than or equal to"

From given,

sum of a number times 9 and 30 = 9x + 30

Which means,

[tex]9x +30\geq 30[/tex]

Thus the given sentence is translated into inequality

The sentence 'The sum of a number times 9 and 30 is at least - 15' can be translated into the inequality

The sentence 'The sum of a number times 9 and 30 is at least - 15' can be translated into an inequality by first recognizing the mathematical operations being described. The phrase 'a number times 9' is multiplication, so let's represent this number with the variable c. Thus, this part is 9c. The word 'sum' represents addition. Finally, 'is at least' indicates that the sum is greater than or equal to a particular value (-15 in this case).

Putting these elements together, we get the inequality

This is the inequality that represents the sentence.

The volume of a cube is found by cubing the edge length — or multiplying it by itself twice.

In other words, the volume of a cube is as follows:

[tex]V=e*e*e[/tex]

Simplified:

To find the edge length from the volume, you'd have to do the opposite, which is to find the cubic root.

Answer:

y = 10

Step-by-step explanation:
