Answer:

The equation you need for 3 is the volume of a sphere.

Then divide 12 by 2 to get the radius, which gives you 6, then insert this into the equation, and the answer you get for 3 is 904.78cm cubed. 904.8 (4 Significant figures) cm cubed.

Blanca jogged 8 days last month she jogged 1.25 miles on each day and burned 140 calories per mile while jogging how many calori
xz_007 [3.2K]

Answer:

140p calories

Step-by-step explanation:

Bianca is said to have jogged km 8 days, while also completing 1.25 miles every day. First, we calculate the total number of miles Bianca jogged in total, and that is

8 * 1.25 = 10 miles

Therefore, Bianca jogged a total of 10 miles the previous month.

Again, it is said that Bianca burned 140 calories per each mile she jogged and were asked to find the total calories that was burnt.

If Bianca burns 140 calories per mile, then she must have burnt 140 * 10 calories in 10 miles.

Therefore, we conclude that Bianca burnt 1400 calories.

Mr. Littles is building a triangular sandbox using three boards. He already has two boards that measure 9 feet and 12 feet. Sele
Bess [88]

Answer:

  • 9 feet, 15 feet, 19 feet

Step-by-step explanation:

<u><em> Options are: </em></u>

  • <em>2 feet </em>
  • <em>3 feet </em>
  • <em>9 feet </em>
  • <em>15 feet </em>
  • <em>19 feet </em>
  • <em>21 feet </em>
  • <em>30 feet</em>

<em>-------------------------------------</em>

Use the triangle inequality theorem: sum of any two side must be greater than the third side by length

  • 2 feet     ⇒  no, as 2 + 9 < 12
  • 3 feet     ⇒  no, as 3 + 9 = 12
  • 9 feet     ⇒  yes
  • 15 feet    ⇒  yes
  • 19 feet    ⇒  yes
  • 21 feet    ⇒  no, as 9 + 12 = 21
  • 30 feet  ⇒  no, as 9 + 12 < 30
