Answer: 7.9 cm

Step-by-step explanation:

Given : This figure is 1/4 of a circle.

The radius of the figure = 5 inch

We know that the perimeter of the circle is given by :-

perimeter =2\pi r

Then the perimeter of 1/4 of the circle is given by :-

perimeter =\frac{1}{4}\times2\pi r

\\\Rightarrow\ perimeter =\frac{1}{4}\times2(3.14)\times5.........[since\ \pi=3.14]\\\\\Rightarrow\perimeter=7.85\approx7.9\ cm

Hence, the perimeter of the given figure = 7.9 cm

Set up an equation to find x, Explain why you used this equation
stiv31 [10]
Answer: 180= 38+(17x+1)+(3x+1), All the angles in a triangle add up to 180 degrees, so I made all the add measures equal to 180 degrees.

Just solve that equation to find x. Then used then plug in the x value to (17x+1). After you solve that put it equal to 2y to solve for y.

So the y equation would look like: 2y=(17x+1) (but you would have solved for x and then plugged it in to the equation)

If you need help solving or have any questions let me know!

The length of a rectangle is 4 more than it's width. Write an equation that will determine the dimensions if the area of the rec
Firdavs [7]

Answer: The equation is W^2 + 4W - 96= 0

{Please note that ^2 means raised to the power of 2}

Step-by-step explanation: We have been given hints as to the measurement of the length and width of the rectangle. The length is given as four more than the width. What that means is that whatever is the width, we simply add four to get the measurement of the length. Therefore if the width is W, then the length is W + 4.

That is,

L = W + 4 and

W = W

Also we have the area given as 96.

Remember that the area of a rectangle is given as

Area = L x W.

In this question, the Area is expressed as

Area = (W + 4) x W

96 = W^2 + 4W

Subtract 96 from both sides of the equation and we have

W^2 + 4W - 96 = 0.

We now have a quadratic equation from which we can determine the dimensions of the rectangle

Solve 41-9+(8×2.3)-15+(2.1×4)
dsp73
(8x2.3)= (18.4)
(2.1x4)= (8.4)
Now you should have:
41-9+18.4-15+8.4
9+18= 27
15+8.4= 23.4
Should have:
41-27-23.4= -9.4
