Answer:

678.24cm³

Step-by-step explanation:

Volume of cylinder = # r² h

Where # = 3.14

r = radius = d/2 = 12/2 = 6cm

h = 6cm

Therefore

Volume = #r²h

= 3.14 × 6² × 6

= 3.14 × 36 × 6

= 678.24cm³

CaHeK987 [17]

Answer:

No

Step-by-step explanation:

Assuming it take 1 buckle and 1 strap per collar, that means we just need to find the lowest common multiple of these 10-pack buckles and 12-pack straps.

For 10: 0, 10, 20, 30, 40, 50, "60", 70, 80, 90, 100...

For 12: 0, 12, 24, 36, 48, "60", 72, 84, 96, 108, 120...

From this, it is obvious that 60 is the lowest common multiple of these two numbers. Therefore, we know that Stefan can make dog collars without having leftover supplies by using 6 10-pack buckles and 5 12-pack straps.

From this, we know that Stefan does not need to buy 120 of either the buckles or the straps.

PLEASE HELLLP!!!!! If x+7=2y and y=2x−1, what is the value of y? (NOT 13)
oee [108]

Answer:

(C) 5

Step-by-step explanation:

x+7=2y

<em>Subtract 7 from both sides</em>

x=2y-7

2y-7=x

<em>Multiply both sides by 2</em>

4y-14=2x

y=2x−1

<em>Add 1 to both sides</em>

y+1=2x

<u>Combine equations:</u>

y+1=4y-14

<em>Add 14 to both sides</em>

y+15=4y

<em>Subtract y from both sides</em>

15=3y

3y=15

<em>Divide both sides by 3</em>

y=5

<u>The answer is </u><u>(C) 5.</u>
