tan 63 = 8/(distance to the well)
distance to the well = 8/tan 63 = 4 m

The best approximation for the distance is 3.) 4 meters. Since the resulting figure forms a right triangle, you can use the mnemonic SOHCAHTOA. Since the angle has an opposite given distance while the value to be solved is adjacent to the angle, use TOA or Tangentθ = Opposite Side/Adjacent side. Wherein θ represents the angle.

So the equation looks like this:

Tangent (63) = 8m / x
1.96 = 8m/x
0.245 = 1/x
1 / 0.245 = x
X = 4.08m

Select the correct answer. A linear function has a y-intercept of -12 and a slope of 3/2. What is the equation of the line? y =

aniked [119]

Answer:

The equation of the line is:

$y\:=\:\frac{3}{2}x\:-12$

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

m is the slope

b is the y-intercept

Given

y-intercept b = -12

slope m = 3/2

now substituting b = -12 and m = 3/2 in the slope-intercept form of line equation

$y = mx+b$

$y\:=\:\frac{3}{2}x\:+\:\left(-12\right)$

$y\:=\:\frac{3}{2}x\:-12$

Therefore, the equation of the line is:

$y\:=\:\frac{3}{2}x\:-12$

Divide 270 in the ratio 3:2:1

Contact [7]

3 + 2 + 1 = 6

270 ÷ 6 = 45

45 × 3 = 135

45 × 2 = 90

45 × 1 = 45

3 : 2 : 1

135 : 90 : 45

I ONLY NEED HELP ON NUMBER 2

REY [17]

So, the area of a circle is a=pi r^2
so do that and get a=pi(4)
and since the circle touches the edge of the rectangle, the rectangle is 4 cm tall, so 4*8 is 32 and pi(4) is about 12.56, so 32-12.56 is 19.44, and I believe that is the answer. (19.4)

a soccar team spent $55 dollars on supplies for a car wash then earned $275 whats their total after paying for supplies

IrinaK [193]

To find what profit they made, subtract what they earned from what they spent money on. 275-55=220. They made a total of $220 after paying for supplies. I hope this helps! :)
