Ray Of Light [21]

Answer:

n = 4

Step-by-step explanation:

Amanda has 1/2 of a yard of fabric that she wants to use to make bias tape. Each requires 1/8 yards of bias tape. We need to find the no of pieces of bias tape she can make.

It means,

n=\dfrac{1}{2}/\dfrac{1}{8}\\\\n=\dfrac{\dfrac{1}{2}}{\dfrac{1}{8}}\\\\n=4

Hence, she can make 4 pieces of bias tape.

Explain your answer !! <br> Have a nice day <br><br> Will give braisnlt
Viktor [21]

Answer:

(3,-4) or x=3 and y= -4

Step-by-step explanation:

I'm going to solve this by substitution

We first need to get a variable by itself in one of the two equations (it doesn't matter which variable and the equation you do the work on doesn't matter either)

I'm going to solve for y in the second equation

-4x-4y=4

add 4y and subtract 4 from both sides to get

-4x-4=4y

Divide by 4 to get

-x-1=y

We can plug this value in for y into the first equation and get

4x+5(-x-1)= -8

Solve for x

4x-5x-5= -8

-x-5= -8

-x= -3

x=3

We can plug this value into one of the first two equations and solve for y

4(3)+5y= -8

12+5y= -8

5y= -20

y= -4

Therefore the solution is (3,-4) or x=3 and y= -4

The measure of the central angle is 4 radians

<h3><u>Solution:</u></h3>

Given that central angle of a circle intercepts an arc of length 28 centimeters

The radius of the circle is 7 centimeters

<em><u>To find: measure of the central angle in radians</u></em>

The arc length of circle when \theta is measured in radians is given as:

s = r \theta

Where "s" is the arc length

"r" is the radius of circle

\theta is the central angle in radians

Substituting the values in formula,

28 = 7 \times \theta\\\\\theta = \frac{28}{7} = 4

Thus the measure of the central angle is 4 radians
