4. Find the area of each triangle. The formula is A=1/2(bh) so the area of the first triangle is 6, Bc 3•4 is 12, divided by 2 is 6.

The area of the second triangle is 24, because 6•8 is 48, divided by 2 is 24. And 24 is four times the value of 6, making the area scale factor 4.

Hope this helped!

different animals have different fields of view. humans can generally see a 180° arc in front of them. horses can see 215° arc.
IgorLugansk [536]

Answer:

The area of the riders field of view is 987.5 square yards.

Step-by-step explanation:

The human has a 180° arc view. If the rider can see only 25 yards, the area of the riders field of view is a semi-circle (180° arc) of 25 yards of radius.

The semi-circle of 25 yards of radius has an area of:

S=\dfrac{1}{2}\pi r^2=\dfrac{1}{2}\cdot3.16\cdot (25)^2=\dfrac{1}{2}\cdot3.16\cdot625=987.5

The area of the riders field of view is 987.5 square yards.

A town has a population of 170000 and grows at 4% every year.what will be the population after 12 years
Aneli [31]

Answer:

\large \boxed{272175}

Step-by-step explanation:

We can use the exponential growth formula:

y = a(1+r)ˣ

where

y = amount after x time

a = initial amount

r = growth rate as a decimal fraction

x = number of years

Data:

a = 170 000

r = 0.04

Calculations:

\begin{array}{rcll}y &= &170 000(1.04)^{12} & & \\& = &170 000 \times 1.601032 &\\& = &\mathbf{272175} &\\\end{array}\\\text{The population will be $\large \boxed{\mathbf{272175}}$ in 12 yr}

The figure below also shows that the population will grow to about 272 000 in 12 yr.
