Answer:

40:15 = 8:3

Step-by-step explanation:

This is the answer because:

1) Since there are 40 elephants and 15 baby elephants, the answer would be 40:15, but we want to simplify the ratio. In order to simplify the ratio, just divide each number by 5:

40 ÷ 5 = 8

15 ÷ 5 = 3

8:3

Therefore, the answer is 8:3.

Hope this helps! :D

What two numbers add to be 6 and multiply to be 15
yarga [219]
   
\displaystyle \bf \\
x_1+x_2=6\\\\
x_1\cdot x_2=15\\\\
\Longrightarrow~~x^2-6x+15=0\\\\
x_{12}=\frac{-b\pm\sqrt{b^2-4ac}}{2a}=\frac{6\pm\sqrt{36-60}}{2}=\\\\
=\frac{6\pm\sqrt{-24}}{2}=\frac{6\pm2\sqrt{-6} }{2}=3\pm i\sqrt{6}\\\\
x_1=\boxed{3-i\sqrt{6}}\\\\
x_2=\boxed{3+i\sqrt{6}}\\\\
\texttt{Verify:}\\\\
x_1+x_2=3-\underline{i\sqrt{6}}+3+\underline{i\sqrt{6}}=3+3=6~~correct\\\\
x_1\cdot x_2=(3-i\sqrt{6})(3+i\sqrt{6})=3^2-(i\sqrt{6})^2=9+6=15~~correct

HELP PLZ I NEED THIS DONE BY TMRW
Kazeer [188]

Answer:

0.75ft per square

Step-by-step explanation:

We know that the number of squares is 24 so we need to determine the dimension of 1 square.

We know the width is 4.5 and we also know that there are 6 squares within that area.

Therefore we can use a fraction to find our answer.

\frac{4.5}{6} > 0.75
