Length = x
width = y
y = 16
x = 2y
x = 2(16)
x = 32
perimeter = 2x + 2y
= 2(32) + 2(16)
= 64 + 32
= 96
See the picture to better understand the problem
we know that
in the triangle ABC
∠A+∠B+∠C=180°
find ∠C
∠C=180-[80+65]------> ∠C=35°
Applying the law of sines
AB/sin C=CB/sin A
solve for CB
CB=AB*sin A/sin C-----> CB=45*sin 65/sin 35-----> CB=71.10 ft
the answer is<span>
the distance from person B to the top of the hill is 71.10 feet</span>
Answer:
See below and attached.
Step-by-step explanation:
Draw a rectangle.
Divide it in half.
Divide each part in half again.
Lastly, divide each part again in half.
This will give a total of 8 sections.
Project a uses 1/2 of the fabric. This means it will use 4 out of the 8 pieces.
Project b uses 1/4 of the fabric. This means it will use 2 out of 8 pieces.
So the fabric that is left is 1 - 1/2 - 1/4 = 1/4.
You can find the amount left for any number of yards of fabric by taking f(x) = x/8 - 3/4
102/250
So, fractions basically mean division.
So, you divide 102 by 250 and you get = 0.408
Answer = 0.408
Answer:
x=0 and y=−8
Step-by-step explanation:
4x+4y=−32
4x−4y=32
Add these equations to eliminate y:
8x=0
Then solve 8x=0 for x:
8x=0
(Divide both sides by 8 to get x by itself)
x=0
Now we plug x back in to solve for y.
4x+4y=−32
Substitute 0 for x
(4)(0)+4y=−32
4y=−32 (Simplify both sides of the equation)
(Divide both sides by 4 to get y by itself)
y=−8
