Here's how I like to represent this:

Randy = 7

Randy * 2 = Ann

Ann + 3 = Janet

Janet + 5 = Donald

If we go along and fill in the blanks for each equation, we do this:

7 * 2 = 14

14 + 3 = 17

17 + 5 = 22

So Donald solved 22 problems.

Hope this helps!

Can someone solve this

Answer:

A ≈ 269.81 cm²

Step-by-step explanation:

This shape is a hexagon (it has 6 sides) so let's use the formula for the area of a hexagon.

A = $\frac{3\sqrt{3} }{2} s^{2}$

Where s is the length of the sides

Substitute:

A = $\frac{3\sqrt{3} }{2} s^{2}$

A = $\frac{3\sqrt{3} }{2} 10^{2}$

Solve:

A = $\frac{3\sqrt{3} }{2} 10^{2}$

A = $\frac{3\sqrt{3} }{2} 100$

Multiply the numerator:

A = $\frac{3\sqrt{3} }{2} 100$

A ≈ $\frac{5.12 }{2} 100$

(The numerator reflects a rounded number, but the actual calculations are exact)

Divide the fraction:

A ≈ $\frac{5.12 }{2} 100$

A ≈ 2.6(100)

Multiply:

A ≈ 2.6(100)

A ≈ 269.81 cm²

Therefore, the area is approximately 269.82 cubic centimeters.

Please help look at picture. 26 points for helping

It's 21 square units. If you map it on a complex plane (x-axis is real numbers, y-axis is imaginary numbers) you'll see that the sides of the rectangle is 3 and 7 which multiply to 21.

Please help me 16% of what is 41?

saul85 [17]

The answer is 256.25

EXPLANATION

Let $x$ represent the number.

Then, $\frac{16}{100}x=41$

We cross multiply yo obtain,

$16x=41\times 100$

We now divide both sides by 16.

$x=\frac{4100}{16}$

This will give us,

$x=256.25$

Therefore the number is 256.26
