Answer:

c = 12.5

Step-by-step explanation:

a² + b² = c²

10 and 7.5 are bases of the triangle, that means they stand for a and b

the equation would be

10² + 7.5² = c²

square the numbers

100 + 56.25 = c²

156.25 = c²

√156.25 = √c²

12.5 = c

Mrs Allen gave some peanuts to her children to take to the zoo. Zach got half the peanuts, Wendy got one-fourth of what was left

Effectus [21]

Answer:

240 peanuts

Step-by-step explanation:

Let x be the number of peanuts Mr. Allen had.

Zach got half the peanuts, then Zach got $\dfrac{x}{2}$ peanuts and

$x-\dfrac{x}{2}=\dfrac{x}{2}$ peanuts left.

Wendy got one-fourth of what was left, then Wendy got

$\dfrac{1}{4}\cdot \dfrac{x}{2}=\dfrac{x}{8}$ peanuts and

$\dfrac{x}{2}-\dfrac{x}{8}=\dfrac{3x}{8}$ peanuts left.

The twins, Ron and Don shared the remaining peanuts, then each of them got

$\dfrac{1}{2}\cdot \dfrac{3x}{8}=\dfrac{3x}{16}$ peanuts.

If Ron got 45 peanuts, then

$\dfrac{3x}{16}=45,\\ \\3x=45\cdot 16,\\ \\x=15\cdot 16,\\ \\x=240\ \text{peanuts.}$

6x+3<27 or 1/4x+3>=6

densk [106]

The correct answer that fits on the line would be x<4. bc the other side the final answer is
$x \geqslant 21$

and that is to big for the line.
the correct answer is x<4 then on the line you would put nonfilled in circle on number 4 and have the arrow and line go to the left
