200 = 16(6t − 3) solve this and show the work please

amm1812

Answer:

t = 2.58333

Step-by-step explanation:

use the distributive property:

200 = 16(6t - 3)

multiply the 16 to each value in the parenthesis:

200 = 96t - 48

now add 48 to both sides:

200 = 96t - 48

+48 + 48

248 = 96t

now divide each side by 96:

248/96 = 96t/96

t = 2.583333

decimal form: 2.5833333

mixed number: $2\frac{7}{12}$

There are 7 similarly shaped figures in a set. The largest figure is 7 inches tall. Each of the other figures is 1 inch shorter

galben [10]

The first thing we must do for this case is to find the scale factor based on the dimensions of the figures.
The largest figure is 7 inches tall. Each of the other figures is 1 inch shorter than the next larger figure.
We have then that the smallest figure has a height of 1 inch.
The scale factor is:
k = (smallest figure) / (largest figure) = 1/7
k = 1/7
The surface area of the smaller figure is:
A = k ^ 2 * (A ')
Where
A ': surface area of the largest figure.
Substituting:
A = (1/7) ^ 2 * (588)
A = 12 in ^ 2
Answer:
The surface area of the smallest figure is:
A = 12 in ^ 2

Find the area of the blue sector(s). The diameter of the wheel is 12

Ber [7]

We know that to find the area of the entire circle, we are going to use the equation:

$A=\pi r^{2}$

And we know that the diameter is 12. To find the radius, we divide the diameter by 2, so 12/2 = 6. So the radius is 6.

Now we can use this radius in the equation:

$A=\pi (6)^{2}$

$A=36\pi$

Since all of the angles of each section are equal, we can assume that each of the sections has an equal area. There are 5 sections, so we need to divide $36 \pi$ by 5 to find the area of each section:

$\frac{36 \pi}{5} =7.2 \pi$

Each section has an area of $7.2\pi units^{2}$ or, using 3.14 for pi, $7.2*3.14=22.61units^{2}$ .

Since we are told to find the area of the blue sections, we know that there are 2 sections that are blue. So we need to multiply the area of each section by 2, to find the area of two of the sections:

$22.61*2=45.22units^{2}$

Therefore, the answer is C) 45.2 $units^{2}$ .
