Answer:

The y-value in which the line crosses the x-axis

Step-by-step explanation:

The y-intercept represents the point where the line crosses the x-axis. Inversely, the x-intercept represents the point/ y-value where the line crosses the y-axis.

Find the volume of the composite solid. Round your answer to the nearest tenth

Vesna [10]

Answer:

V = 1206.3 $ft^{3}$

Step-by-step explanation:

This shape is made up of a cylinder on the bottom and a cone on the top. We'll find the volumes of these shapes separately and then add them together.

Volume of a cylinder = area (of the base) x height

Substitute in the formula for the area of a circle.

V(cylinder) = $\pi$ $r^{2}$ x h

Substitute in the values for the radius (8) and height (4)

V(cylinder) = $\pi$ x $8^{2}$ x 4

Evaluate using a calculator

V(cylinder) = 804.2477

To the nearest tenth, V(cylinder) = 804.2

Volume of a cone = $\frac{\pi r^{2}h }{3}$ . This is the area of the circular part of the cone ( $\pi r^{2}$ ), multiplied by the height from the point to the base, all divided by 3.

Substitute in the values for the radius of the circle (8) and the height (6)

V(cone) = $\frac{\pi 8^{2} 6 }{3}$ (On the top it's $\pi$ x $8^{2}$ x 6)

Evaluate using a calculator

V(cone) = 402.1239

To the nearest tenth, V(cone) = 402.1

Total volume = V(cylinder) + V(cone)

= 804.2 + 402.1

= 1206.3 $ft^{3}$

The kwon family has a rainwater catchment system they use to water their garden. the storage tank is 72 inches deep. three hours

atroni [7]

The tank is filling at the rate of (58-36) in/(5-3 h) = 22/2 = 11 in/h.

72-58 = 14 inches more to fill

<span>
The remaining 14 inches will be filled in
14 /11 = 1.27 , round to 1.3 hours</span>

so total time would be 5 +1.3 = 6.3 hours

If two siblings are boys, what is likelihood that the third sibling will also be a boy

melamori03 [73]

The is a 50% chance of being a boy or a girl.....previous siblings do not matter. Every child is an independent event. So even if u had 2 siblings that were boys, the result of the next one being a boy is still gonna be 50%...just as the odds of it being a girl, is 50% as well.
