Answer:

(a) Planet A: 1,000,000,000

Planet B: 10,000,000

Planet C: 100,000,000

[10^n will always equal a 1 followed by n zeroes. So 10^9 was a 1 followed by 9 zeroes which equals 1,000,000,000 or 1 billion]

(b) Dwarf Planet: 2 x 10^6

[Multiply the radius by 2 to get the diameter. So the dwarf planet's diameter is 2/100 of Planet C's diameter. You then multiply the 2/100 by Planet C's diameter to get 2,000,000 or 2 x 10^6

This year, a company produced 8 percent more items than last year. If the company produced 243 items this year, how many items d

Ilya [14]

Answer:

Last year company produce 225 items

Step-by-step explanation:

let the number of items produced last year be x

Here we are asked to find the percent increase in the production of the items from last year

The production for the last year = x

The production for the current year = 243

Total increased production =243-x

Hence percentage calculation = $\frac{\increase \in \sale}{\last \year \sale} \times 100$ %

Increased percentage = $\frac{243-x}{x} \times 100$ %

Percentage increased = 8 %

Hence

$\frac{243-x}{x} \times 100 = 8$

${243-x}\times 100 = 8 \times x$

$24300-100x = 8x$

$24300=100x+8x$

$24300=108x$

$x= \frac{24300}{108}$

x=225

Hence Last year production was 225 items

Question 5 (1 point)

bearhunter [10]

Answer:

$T(x)=84-2x$

Step-by-step explanation:

Linear Modeling

The initial temperature outside is 84 degrees.

We are told the temperature drops 2 degrees every hour.

Let's call x to the number of hours elapsed. After x hours, the temperature would have dropped by 2x degrees, since it's a rate of 2 degrees per hour.

That drop is subtracted from the initial temperature to produce the linear model as follows:

$\mathbf{T(x)=84-2x}$

This is the linear equation that represents the described situation.

Answer:

it would take 20 miles and cost 10 dollars.

Step-by-step explanation: Like up the equations so that 50x=40x+200. When you solve for x (number of miles) you find that x=20. Use 20 in either equation (0.5x or 0.4x+2) to get 10 (total cost).
