Americans who are 65 years of age or older make up 13.1% of the total population. If there are 32.6 million Americans in this age group, find the total U.S. population.

Answer:

[tex] - \frac{18}{ {b}^{4} } [/tex]

Step-by-step explanation:

[tex] - 18b {}^{ - 4} [/tex]

express b^-4 with a positive exponent using:

[tex]a {}^{ - n} = \frac{1}{ {a}^{n} } [/tex]

[tex] - 18 \frac{1}{ {b}^{4} } [/tex]

[tex] - \frac{18}{ {b}^{4} } [/tex]

Let me know if I should change anything or if the answer was perfect!!!

Answer: First Option | 2 x 10^1

Reason: After doing 6.4 divided by 3.2, you get 2, and finally you subtract 10³ by 10². And after that subtraction, you get 10^1, Therefore the answer is the first option.

I hope this helps, and Happy Holidays! :)

Answer:106 I think

Answer:

y = 3x -1

Step-by-step explanation:

The given area of the farm, A_0=1 hectare.

The fraction of the farm for cultivating tomatoes = 1/2

The fraction of the farm for cultivating lettuce = 2/5

The remaining fraction of farm for onion = 1-(1/2+2/5)=1/10

Therefore, the fraction of farm dedicated to onion is 1/10.

Now, the area dedicated to tomatoes = 1/2 of the area of land.

=1/2 x 1 = 1/2 hectare.

The area dedicated to lettuce = 2/5 of the area of land.

=2/5 x 1 = 2/5 hectare.

The area dedicated to onion = 1/10 of the area of land.

=1/10 x 1 = 1/10 hectare.

Answer:

48ft^2

Step-by-step explanation:

Given that:

Small and large Spheres have a scale factor of 1 : 3

Hence,

Smaller sphere = 1

Larger sphere = 3

Surface area of smaller sphere = 16ft^2

Hence,

Surface area of larger sphere = (3 * 16ft^2) = 48ft^2

Answer:

50 minutes

Answer:

  k = -1

Step-by-step explanation:

Subtract 10 and simplify. We choose this value so the constants on the right add up to give 0.

  3 -10 = 3 + 7k + 7 -10

 -7 = 7k

Divide by 7.

  -7/7 = 7k/7

  -1 = k

Answer:

Answer:

y=-2x-2

Step-by-step explanation:

y-4=-2(x+3)

Remove parentheses

y-4=-2x-6

Move your constant to the right

4=-2x-6+4

Calculate the sum

y= -2x-2

Answer:

its B

Step-by-step explanation:

If he deposits $56,000 into an account that pays 2.92% interest compounded daily, it takes for his money to grow to the desired amount will be 21.7 years. Option b is correct.

It is defined as the interest based on the principal amount, it does not include the compounded amount. The interest calculates on the initial amount or borrowed amount.

It is given that,

Principal(P) = $56,000

Rate(R) = 2.92%

Time(T) = x years

Interest(I)=?

The amount to be collected to save the money is,

=$92,400 - $56,000

=$36,400

Interest = $36,400

The formula for the simple interest is,

I=(P×R×T)/100

Substitute the given value as

[tex]\rm 36400=\frac{\left(56000\times \:2.92T\right)}{100} \\\\ \frac{\left(56000\times \:2.92T\right)}{100}=36400 \\\\ \frac{100\times \:56000\times \:2.92T}{100}=36400\times \:100 \\\\ 163520T=3640000 \\\\ T=\frac{1625}{73} \\\\ T=21.7 \ years[/tex]

Thus, if he deposits $56,000 into an account that pays 2.92% interest compounded daily, it takes for his money to grow to the desired amount will be 21.7 years. Option b is correct.

Final Answer: [tex]g = 1[/tex]

Steps/Reasons/Explanation:

Question: How do you solve [tex]-3 + 5 +6g = 11 - 3g?[/tex]

Step 1: Simplify [tex]-3 + 5 + 6g[/tex] to [tex]6g + 2[/tex].

[tex]6g + 2 = 11 - 3g[/tex]

Step 2: Subtract [tex]2[/tex] from both sides.

[tex]6g = 11 - 3g - 2[/tex]

Step 3: Simplify [tex]11 - 3g - 2[/tex] to [tex]-3g + 9[/tex].

[tex]6g = -3g + 9[/tex]

Step 4: Add [tex]3g[/tex] to both sides.

[tex]6g + 3g = 9[/tex]

Step 5: Simplify [tex]6g + 3g[/tex] to [tex]9g[/tex].

[tex]9g = 9[/tex]

Step 6: Divide both sides by [tex]9[/tex].

[tex]g = 1[/tex]

Answer:

1/15 pie

Step-by-step explanation:

An easy way to do this is instead of dividing, multiply the denominator by 5. You get 15. You can say Im just making a coincidence, but try it yourself!

(1/3)/5 is basically multiplication. You may have heard the saying, "division with fractions is multiplication". Thats true. Turn 5 into 5/1 and multiply. 5/1x1/3.

you get 1/15. Hope it helps

Also you have to flip 5/1 to 1/5 and then multiply hehe. thats how you get 1/15
