Answer:

8

Step-by-step explanation:

Hello,

This is related to ratios and proportions. We have a 12 foot tree that casts a 6 foot shadow, so now we are trying to figure out how tall is a tree that casts a 4 foot shadow.

We can set an easier method to get this.

12 = 6 (this means the 12 foot tree casts a 6 foot shadow)

x = 4 (this means how tall is the tree to cast a 4 foot shadow, the unknown height of the tree is denoted as x)

Then, we can cross multiply.

48 = 6x

Solve for x, which is the unknown height we are trying to figure out.

x = 8

Answer:

-2,4/3

Step-by-step explanation:

ax²+bx+c=0

x=\frac{-b \pm\sqrt{b^2-4ac} }{2a} \\3n^2+2n-8=0\\n=\frac{-2\pm\sqrt{2^2-4*3*(-8)} }{2*3} \\n=\frac{-2 \pm \sqrt{4+96}}{6} }\\n=\frac{-2 \pm 10}{6} \\n=\frac{8}{6} =\frac{4}{3}\\or~n=\frac{-12}{6}=-2

120 meals to 52 meals what is the percentage change?
Oksi-84 [34.3K]

Answer: The percentage change is 56.67%.

Step-by-step explanation:

From 120 meals to 52 meals, change in meals = ( 120- 52) meals

= 68 meals

The percentage change = \dfrac{\text{change in meals}}{\text{Original quantity of meals}}\times100

=\dfrac{68}{120}\times100\\\\=56.67\%

Hence, the percentage change is 56.67%.
