Kelly is in a hot air balloon that has just taken off and is now floating 7 meters above its launching point. Denise is standing on the ground, 7 meters away from the launching point. How far apart are Kelly and Denise? If necessary, round to the nearest tenth. For 8th grade\

Answers

Answer 1

Answer:

9.9 meters

Step-by-step explanation:

Given that the distance between Kelly and launching point was 7m and also the distance between launching point and Dennis was also 7m, to calculate for the distance between Kelly and denise is done by applying the formula used for calculating the hypotenuse in a right angle triangle (the shape that was created)

Which of the following correctly shows the length of each radius, the point where the circles intersect, and the equation of the tangent line at this point? HELP PLEASE!!

Answers

The answer is the third one.

The first two are easy, you can see that the radius of S is 4 and the radius of T is 5-4=1.

The point of intersection is where the two circles touch each other, and is is (4, 1), because you have to put the x value first.

The equation of the tangent line is just y=4, because it is a straight vertical line.

A party hat has a volume of 75 cubic inches . If the radius is 5 inches , what is the height of the party hat?

Answers

The height of the party hat is 2.63 inches.

Given that,

A party hat has a volume of 75 cubic inches.

If the radius is 5 inches,

We have to determine,

What is the height of the party hat?

According to the question,

A party hat has a volume of 75 cubic inches.

If the radius is 5 inches,

The volume of the cone is determined by the formula,

$\rm v = \pi r^2(h)/(3)$

Then,

The height of the party hat is,

$\rm v = \pi r^2(h)/(3)\n\n75 = \pi* (5)^2 * (h)/(3)\n\n75 = 25 * (22)/(7) * (h)/(3)\n\n75 = 25 * 1.14 * h\n\n75 = 28.5 * h\n\nh = (75)/(28.5)\n\nh =2.63$

Hence, The height of the party hat is 2.63 inches.

Answer:

About 2.86 inches

Step-by-step explanation:

The formula for the volume of a cone is $\pi r^2(h)/(3)$ . Plugging the known numbers into this formula, you get:

$75=\pi \cdot 5^2\cdot (h)/(3)$

$(h)/(3)\approx 0.955$

$h\approx 2.86$ inches. Hope this helps!
