Nuetrik [128]

Answer:

Step-by-step explanation:

It says P = per ball (which will be a number, n, for balls times the fixed price) plus a set entrance fee. So we find that the price per ball is $0.80, so 10 balls cost $8.

The ratio of solid beads to clear beads in a vase is 820. Select all the correct statements that tell if the operations will giv

Tatiana [17]

Answer:

C, D and E

Step-by-step explanation:

Given

Represent solid beads with S and clear beads with C

So:

$S:C = 8:20$

Required

Select operations that give an equivalent ratio

First, we need to get the unit ratio

$S:C = 8:20$

Divide through by 4

$S:C = 2:5$ -- This means that, after any operation. The equivalent ratio must be 2: 5

Option A: Add 2 to S and 2 to C

$S:C = 8:20$

Perform the operation

$S:C = 8 + 2 : 20 + 2$

$S:C = 10 : 22$

Divide through by 2

$S:C = 5:11$

Option B: Subtract 8 from S and 6 from C

$S:C = 8:20$

Perform the operation

$S:C = 8 - 8 : 20 - 6$

$S:C = 0 : 14$

Option C: Multiply S and C by 2

$S:C = 8:20$

Perform the operation

$S:C = 8*2:20*2$

$S:C = 16:40$

Divide through by 8

$S:C = 2:5$

Option D: Divide S and C by 4

$S:C = 8:20$

Perform the operation

$S:C = 8/2:20/4$

$S:C = 2:5$

Option E: Multiply S and C by 18

$S:C = 8:20$

Perform the operation

$S:C = 8*18:20*18$

$S:C = 144:360$

Divide through by 72

$S:C = 144/72:360/72$

$S:C = 2:5$

<em>From the calculations above, options C, D and E gave an equivalent of 2:5.</em>
