Answer:

x < 4

x > - 2.25

= 4 > x > - 2.25

Step-by-step explanation:

5x - 19 < 1

5x < 1 + 19

5x < 20

x < 20/5

x < 4

- 4x + 3 < - 6

What is the sum 2, 3, 4, and 5?

borishaifa [10]

Answer:

Step-by-step explanation:

We can find the sum of these numbers by adding them together.

The cumulative rule of addition lets us add numbers together in any order we want.

So, for 2 + 3 + 4 + 5 …

2 + 3 = 5

So now we have 5 + 4 + 5

5 + 4 = 9

Now we have 9 + 5

And 9 + 5 = 14

So, your answer is 14

Hope this helps!

Hal says the volume of the sphere shown below 36 cm3. Find the correct volume, using 3.14 for pi. Round to the nearest hundredth

adelina 88 [10]

Answer:

Volume of sphere is $35.98cm^3$

Step-by-step explanation:

It is given that Hal says that volume of sphere is $36cm^3$

Volume of sphere is given by $V=\frac{4}{3}\pi r^3$

$\frac{4}{3}\pi r^3=36$

$\pi r^3=27$

$r^3=8.594$

$r=2.048cm$

Now using 3.14 in place of $\pi$

Now volume of sphere is

$V=\frac{4}{3}\times 3.14\times 2.048^3$

$V=35.98cm^3$

Therefore volume of sphere when we use 3.14 in place of $\pi$ is $35.98cm^3$

And the Hal likely error is he uses $\pi$ directly for calculation of volume.
