Answer: 603 cubic inches

Step-by-step explanation:

Let's find radius (r):

Diameter is double the radius, so the radius is 4 inches.

Let's find the height (h):

Height is 3 times the radius so the height is 12 inches.

Now let's find the volume:

V = πr^2 × h

V = π × 16 × 12

V = 603 cubic inches

wlad13 [49]

Answer:

22

Step-by-step explanation:

Solve the inequality  (20 + 0.5x) + 0.15(20 + 0.5x)   ≤ $62.10 for x:

20 + .5x + 3 + 0.75x ≤ 62.10

Combining the x terms, we get:

20 + 3 + 1.25x ≤ 62.10.

Combining the constants on the left:

23 + 1.75x ≤ 62.10

Combining the constants:

1.75x = 39.10

Solving for x:  39.10/1.75 = 22.34

Thus, the max number of whole pages she can have in her book is 22.

⇒ \frac{1}{4}

⇒ 0.25

Therefore, Celia bought a bag of 12 goldfish for $3  , Cost of 1 goldfish is $0.25 .

olchik [2.2K]

Answer:

The amount of stock for which both brokers would charge the same commission is $2500.

Step-by-step explanation:

i) Let the amount of stock to be traded be worth $x

ii) therefore for both the brokers to charge the same commission we can write

   1% of x  = $25 \RIghtarrow\Rightarrow  0.01 \times x  = 25  \therefore   x = \frac{25}{0.01}  = 2500

The amount of stock for which both brokers would charge the same commission is $2500.
