The larger of two numbers exceeds twice the smaller by one. Three times the smaller exceeds the larger by six. If y is the large

mestny [16]

Step-by-step explanation:

larger number = y

smaller number=x

y>2x+1

y<3x+6

Probably the first one, if I did this right.

To do this problem, you need to know how to read math, <em>literally</em>. The problem says that y is the larger number, so assume the smaller is x. So, y exceeds 2x by 1 (so, y>2x+1). then, it says 3x exceeds y by 6; therefore, 3x+6>y. I may have interpreted it wrong, though, so tell me if I made a mistake :))

One of the corners of a square is shown. A diagonal splits the corner into two angles. Give the size of angle x and angle y.

TEA [102]

Answer:

X+Y=90° (right angle )

*X=1/2(90)

X=45°

45+Y=90°

Y=90°-45°

Y=45°

Changing the inner radius automatically changes the angular velocity to different angular speed. why

fenix001 [56]

The above situation is represented by the equation v = w.r, angular velocity (w) is a constant. Therefore, velocity is inversely proportional to the radius. ( I.e if r increases v decreases and vice versa)

Does x^2+y^2=9 represent y as a function of x?

aleksley [76]

No, x²+y²= 9 does not represent y as a function of x.

For x= 0,

y²= 9

=>y= ±3,

i.e y has two values +3 and -3

Since single value of x , there are two values of y

For an equation or relation to be function every element in domain( every value of x) there should one distinct value or image in co-domain (one value of y)

A can has a radius of 2 inches and a volume of 62.8 cubic inches. Find the height of the can.

irina [24]

ANSWER
The height of the cylinder is,
$h=5inches$

EXPLANATION

The volume of a cylinder can be found using the formula,

$V = \pi {r}^{2} h$

To make h the subject, we divide through by
$\pi \: {r}^{2}$

This will give us,

$\frac{V}{ \pi \: {r}^{2} } = h$

We now substitute

$V=62.8$
$r = 2$
and

$\pi = 3.14$

into the given expression for h to obtain,

$h = \frac{62.8}{3.14 \times {(2)}^{2} }$

We simplify to get,

$h = \frac{62.8}{12.56}$

$h = 5$

Therefore the height of the cylinder is 5 inches.
