Build a fence around his rectangular garden. The length is 30 feet. The width is 6 yards. How many feet of fencing is needed

1 answer:

4 0

The field that is being fenced in has two 30 foot sides and 2 18 foot sides. The reason they are 18 is because there are 3 feet in a yard. You would then add all 4 sides together, equaling your perimeter.

The final answer is 96 sq feet.

Garrett is 3 years older than Rachael. In 2 years the sum of their ages will be 39. How old is Garrett now?

ziro4ka [17]

Let garret’s age be x

x + 2 + (x + 3) + 2 = 39
2x + 7 = 39
2x = 32
x = 32/2
x = 16

Garrett’s age after two years = 16 + 2 = 18

Given sin(−θ)= −1/4 and tanθ= 15√15 .<br><br> What is the value of cosθ ?

dangina [55]

$\sin = \frac{y}{r} \\ \\ \tan = \frac{y}{x} \\ \\ \cos = \frac{x}{r} \\ \\ {x}^{2} + {y}^{2} = {r}^{2}$

$- \sin = \frac{ - 1 \: = \: y}{4 \: = \: r}$
$15 \sqrt{15} = \frac{1}{x} \\ \\ x = .017$
$\cos = \frac{.017}{4} = .0043$
