Expressing y in terms of x is as follows:
y = 25x
They wanted to cut exactly 160 meters of wire from a huge spool. They mistakenly measured mass instead of the length.
x = length of wire in meters
y = weight of wire in grams
Therefore, using proportion
<h3>Proportional relationship:</h3>
Proportional relationship express values in ratios .Therefore,
3 meters wire = 75 grams of wire
x meters = y grams
cross multiply
75x = 3y
let's express y in terms of x as required
Therefore,
divide both sides by 3
y = 75x / 3
y = 25x

Cup A
<em><u>Formula</u></em>
V = 1/3 pi r^2 h
<em><u>Givens</u></em>
r = d/2 = 2/2 = 1 inch
pi = 3.14
h = 4 inches
<em><u>Solution</u></em>
V = 1/3 * 3.14 * 1^2 * 4
V = 4.187
Cup B
<em><u>Formula</u></em>
V = pi * r^2 * h
<em><u>Givens</u></em>
pi = 3.14
r = d/2 = 2/2 = 1
h = 6
<em><u>Solution</u></em>
V = pi * r^2 * h
V = 3.14 * 1^2 * 6
V = 18.84
<em><u>Answer</u></em>
VB - VA = 18.84 cu in - 4.187 = 14.65 = 14.7 Rounded.
Answer C
The answer is 18... hope this helps :D
The perimeter of the large square is 24 and the area is 36 units
the perimeter of the small squares are 4 and the areas are 1 unit.
All together the perimeter is 29 and the area is 38.
The slope-intercept form of a line is:
y=mx+b
m=slope=(y2-y1)/(x2-x1)
b=y-intercept (the value of y when x=zero)
