Romashka [77]3 years ago
3 0

Answer:

The first answer choice: 15 cm x 3.14 cm x 2cm^2 = 188.4 cm^3

Step-by-step explanation:

Formula:

V=πr^2h

radius=2

height=15

V=π(2)^2*15

π(4)*15

4*15=60

60π

π=3.14

60(3.14)

188.4

Since its volume you have to cube it

188.4 cm^3

Can someone help or show me how to simplify this equation 22.5+7(n-3.4)
Scorpion4ik [409]
<span>22.5+7 (n-3.4)=19.8n

We simplify the equation to the form, which is simple to understand
<span>22.5+7(n-3.4)=19.8n

Reorder the terms in parentheses
<span>22.5+(+7n-23.8)=19.8n

Remove unnecessary parentheses
<span>+22.5+7n-23.8=+19.8n

We move all terms containing n to the left and all other terms to the right.
<span>+7n-19.8n=-22.5+23.8

We simplify left and right side of the equation.
<span><span>-12.8n=+1.3

</span>We divide both sides of the equation by -12.8 to get n.
<span>n=-0.1015625</span></span></span></span></span></span></span>

kayden paddled a canoe to an island. the island is 8 miles from the shore. his trip to the island took two hours while paddling
Andrew [12]

Answer:

2\text{ mph}

Step-by-step explanation:

GIVEN: kayden paddled a canoe to an island. the island is 8 miles from the shore. his trip to the island took two hours while paddling against the current. he paddles 6 mph with no current.

TO FIND: what was the speed of the current.

SOLUTION:

distance of island from the shore =8 miles

total time taken by Kayden =2 hours

speed of Kayden in still water =6\text{ mph}

Let the speed of current be x

Speed of Kayden against current =6-x\text{ mph}

As,

\text{Time}=\frac{\text{Distance}}{\text{speed}}

2=\frac{8}{6-x}

12-2x=8

x=2\text{ mph}

Hence speed of current is 2\text{ mph}
