Spencer spent four hours doing chores over the weekend. If he spent 2/3 of an hour for each chore how many chores did he do?

1 answer:

6 0

6 chores (because 4 hours is 240 minutes and 2/3 of an hour is 40 minutes, so you would divide them. Then you would get 240 divided by 40 and the answer would be 6. So Spencer would have done 6 chores)

These three angles are on a line so must total 180°.
So 180-(52+58)=
180-110=70

So angle q is 70°.

Using the given information, the height of the shorter cone is 6.81 cm

<h3>Calculating volume of a cone </h3>

From the question, we are to determine the height of the shorter cone.

First, we will calculate the volume of the first cone

Using the formula for calculating the volume of a cone,

$V = \frac{1}{3}\pi r^{2}h$

Where V is the volume

r is the radius

and h is the height

From the given information,

r = 8.5 cm

h = 10 cm

Then,

$V = \frac{1}{3}\pi \times 8.5^{2}\times 10$

$V = \frac{1}{3}\pi \times 72.25\times 10$

$V = \frac{722.5}{3}\pi$ cm³

Now, for the shorter cone

r = 10.3 cm

Since the two cones have the exact same volume, we can write that

$\frac{722.5}{3}\pi= \frac{1}{3}\pi \times 10.3^{2} \times h$

$722.5= 106.09 \times h$

$h = \frac{722.5}{106.09}$

h = 6.81 cm

Hence, the height of the shorter cone is 6.81 cm.

Find the distance :

faltersainse [42]

1. You would do 45 × 3 = 135 miles
2. 630 ÷ 2 = 315. 630 + 315 = 945 miles
3. 54 × 11 = 594 miles

1. Time is distance ÷ speed, so 4760 ÷ 560 = 8 1/2hours
2. 27 ÷ 54 = 0.5 hours, or 30 minutes
3. 1748 ÷ 437 = 4 hours

I hope this helps!
