10 inches squared because the scale is shown in the legenth the smaller one is 2 and the bigger one is 10 so the smaller one if 5 times smaller so you multiply the area by 5

Well, if GHJK is just a smaller version of LMNP, then they are proportional to each other.

It's saying that the small rectangle is 2 square inches. You can tell then that it is a 2in x 1in rectangle. You know that the ratio of between the long sides is 2:10. If we say that the shorter sides of the larger rectangle is x. Then we should know that the 2:10 proportionality will be true for 1:x. Well, 2 is to 10 as 1 is to 5. So the big rectangle has side lengths of 10 in and 5 inches. I'll let you go from there.

The Reunion Tower is one of the most recognizable landmarks in Dallas, Texas due to the giant sphere that sits atop the structur

ValentinkaMS [17]

The volume of a sphere uses the following formula:

$V = \frac{4}{3}\pi r^{3}$

Because the question asks to use 3.14 in place of pi, the formula will now look like this:

$V = (\frac{4}{3})(3.14)r^{3} = 4.18\overline{66} r^{3}$

We are given a diameter of 118 feet. The radius is half of the diameter, so divide the diameter by 2 to find the radius:

$118 \div 2 = 59$
$r = 59$

Plug this value into the formula, and solve with a calculator:

$4.18\overline{66} \times 59^3 = 4.18\overline{66} \times 205379 = 859853.413$

Although our result is one cubic foot off, the answer is <span>A. 859,852ft^3.

(859,852 is the result if the constant in the given formula is 4.18666, but the result with infinitely repeating numbers is 859,853.)</span>

Which graph would help you find the solutions of 2 – x2 = –x?

Lelechka [254]

Step-by-step explanation:

A quadratic graph will surely help you find the solutions

X2-x-2=0

x1=2 x2= -1

Substitute each of the x value in the original equation to get the y value

(2)^2-(2)-2= 0 (2,0)

(-1)^2-(-1)-2=-2 (-1,-2)

plot the coordinates on the graph,the graph should be a curve
