ANSWER: 18 blue ribbons and 12 red ribbons

Step-by-step explanation:

for every 3 blue ribbons there is 2 red ones

so if we add 3+2 that is 5 then divide 30 by 5 would be 6 and then separate back into basic numbers so there would be 6 threes and six twos so 18 and 12.

Which relation is a function?

sergejj [24]

To determine which relation is a function, we can perform something called the vertical line test. We cover the graph in repeating vertical lines and if one vertical line connects with more than one point of the relation, the relation is not a function.

The relation in the bottom right corner is the only relation that passes the vertical line test.

Can someone please help me ?

Answer:

B. π(3/2)²h

(27/4)π cubic inches

Step-by-step explanation:

A. The formula for the volume of a cylinder is ...

V = πr²h

The radius (r) is half the diameter, so for a diameter of 3 inches, the radius is 3/2 inches. When this is put into the formula, the volume is ...

V = π(3/2)²h . . . . . . matches choice B

B. When h=3, the volume evaluates to ...

V = π(9/4)(3) = (27/4)π . . . . cubic inches

Point c is the center of dilation. line segment b a is dilated to create line segment b prime a prime. the length of c a is 4. t

pychu [463]

The scale factor of the dilation of line segment ba for which the center of dilation is C, is 5.

<h3>What is the dilation of the figure?</h3>

Dilation of a figure, means the transformation of the figure. The factor by which the given figure dilated, called the scale factor of dilation.

Point c is the center of dilation. Line segment BA is dilated to create line segment b prime, a prime. The image of the given problem is attached below. The length of CA is 4.

$CA=4$

The length of a prime is 16.

$AA'=16$

The new dimension will be,

$CA'=CA+AA'\\CA'=4+16\\CA'=20$

Now, the scale factor is the ratio of the new dimension to the original dimension. Thus, the scale factor of the dilation is,

$r=\dfrac{20}{4}\\r=5$

This will be the same for the line segment BA. Thus, the scale factor of the dilation of line segment ba for which the center of dilation is C, is 5.
