Answer:

0.5:1

Step-by-step explanation:

laps:minutes

So we can find how much Ronald runs in 2 minutes, by dividing 6:12 (or 6/12) by 6. This will give you 1:2 (One lap = 2 minutes).

But you're looking for 1 minute, so with 1:2, you have to divide them by 1/2, so it will be 0.5:1.

Find the value of the variable.

Zielflug [23.3K]

Answer:

x = 8, y = $8\sqrt{2}$

Step-by-step explanation:

$a^2+b^2=c^2$

$8^2+8^2=c^2$ Both 8 and x sides are congruent so they're equal.

$64+64=c^2$ Add 64 + 64.

$c^2=128$ Square root 128

$c^2=8\sqrt{2}$

Final answers: x = 8, y = $8\sqrt{2}$

Find the surface area of a cylinder with a base radius of 2 cm and a height of 3 cm.

jek_recluse [69]

Answer: 62.8cm^2

Step-by-step explanation:

The surface area of a cylinder is calculated by 2πrh+2πr2

where π is a constant, given as 3.14; h is the height, given as 3cm and r is radius, given as 2cm.

Therefore, rh = 3 x 2= 6 cm ^2 while r^2 =2 × 2= 4 cm^2.

Slot the values into the formula:

V= 2 (3.14) x 6 + 2 (3.14) x 4

V=37.68 + 25.12

V=62.8cm ^2

I hope this helps
