Answer:
The length of the arc of the quadrant is 40.663 inches
Step-by-step explanation:
The given parameters for the quadrant are;
The dimensions of the rectangle from which the quadrant is cut = 50 inches by 25.9 inches
Therefore, the length of the radius of the quadrant = The shortest side of the rectangle, r = 25.9 inches
Therefore, we have;
The length of the arc of the quadrant = 1/4 × 2 × π × r
Where;
π = 3.14
∴ The length of the arc of the quadrant = 1/4 × 2 × 3.14 × 25.9 = 40.663
The length of the arc of the quadrant = 40.663 inches.
Simplify 2.8y + 6 + 0.2y to 3y + 6
subtract 3y from both sides
simplify 5y - 15 - 3y to 2y - 15
add 15 to both sides
simplify 6 + 15 to 21
divide both sides by 2
switch sides
Answer: y = 21/2
*in decimal form this would be 10.5
4x - 5y = -15
y = -3x + 22
Plug in your y= equation into the y variable in the other equation
4x - 5 (y) = -15
^^
y = (-3x + 22) = -15
4x - 5 (-3x + 22) = -15
Distribute
4x + 15x - 110 = -15
Combine like terms and add 110 over to -15
19x = 95
Then, divide the whole equation by 19
x = 5
Then, plug in your x into your y= equation
y = -3 (5) + 22
y = -15 + 22
y = 7
<em><u>x = 5</u></em>
<em><u>y = 7</u></em>
<em><u>(5, 7)</u></em>
Answer:
Hi there!
Your answer is:
x= 9 when y= 108
Step-by-step explanation:
x= 6 when y=72
/72
x = 1/12 when y =1
<em>So</em><em>:</em>
x= _ when y = 108
x= 1/12 when y =1
×108
x= 9 when y= 108
Hope this helps!
