The variables x and y are related proportionally. When x = 4, y = 14. Find y when x = 40.
When x = 40, y =

Answers

Answer 1

Answer:

See Below

Step-by-step explanation:

Take the the given information and compare to the question being asked

\(\frac{y}{x}\). So insert the x & y's of both equations (ima do y over x to make it easier)

\(\frac{14}{4} =\frac{y}{40}\)

divide 14/4

3.5 = \(\frac{y}{40}\)

then multiply both sides by 40 to isolate y

140 = y

Check by reinserting 140 and divide it by 40

Answer 2

Answer:

y= 140

Step-by-step explanation:

if they are directly proportional, that means when one increases/decreases the other does as well.

x increased by multiplying itself by ten. Like before, since they are both directly proportional that means that y is multiplied by 10.

14*10= 140, y=140

(2/3)(-4)(9) = -24

(5/16)(-2)(-4)(-4/5)= -2

(-3/4)(7/8)=-21/32

(2 3/5) (7/9)=91/45

(2/3) x (-4)(9) -> -24
(5/6) x (-2)(-4) x (-4/5) -> -2

Answer:

A. y = x + 1

Step-by-step explanation:

Line is passing through the points (0, 1) & (2, 3)

slope of line (m) =(3 - 1)/(2 - 0) = 2/2 = 1

y- intercept (b) = 1 [since y -coordinate in (0, 1) is 1]

Equation of line slope-intercept form is given as:

plugging the values of m and b in the above equation, we find:

Answer:

226.19 \(in^{2}\)

Step-by-step explanation:

So to answer the question, we must find the area outside of the bullseye.

In order to do this, we can find the area of the whole circle and subtract the area of the bullseye and what we have left is the area outside of the bullseye.

So the area of a circle is π\(r^{2}\).

We know the bullseye radius is 3 inches so we have r = 3.

= π(\(3^{2}\)) = 9π

The radius of the whole circle is 9 inches. so we have r = 9/

= π(\(9^{2}\)) = 81π

So now we subtract the bullseye from the whole circle to find the region outside the bullseye.

81π - 9π = 72π

Multiplying 72π should get us

= 226.19 \(in^{2}\)
