Step-by-step explanation:

21.46 ≈ 0

Nearest " hundred" ≈ 0

Nearest " hundredth" ≈ 21.46

Nearest " tenth" ≈ 21.5

Rounding a number needs the following:

   Replacing the number with an approximation of the number that

        Results in a more simpler way.

Answer:

21.46 is already rounded to the nearest hundredth place.

Step-by-step explanation:

Two places away from the decimal is the hundredth place, and 21.46 is already rounded to two places.

21. <u>46</u>

No more can be done, unless there was more to the decimal.

$1.79, $1.61, $1.96, $2.09, $1.84, $1.75 <br> ​<br> ​What is the range of gasoline prices?
german

Answer:

0.48

Step-by-step explanation:

The range of a data set is the largest quantity subtracted by the smallest quantity. In this case 1.61 is the smallest. 2.09 is the largest. So we need to do 2.09-1.61 and get the range of 0.48! Stay safe!

What is 2 3/8 * 1/3. Estimate the product
stealth61 [152]
2 3/8 x 1/3 I believe? First you need to change 2 into a 16 then add that into 3 which is 19/8. You multiply across with 1/3 like with numerator with numerator and denominator with denominator. That then equals:19/24. You can't estimate it because 19 is a prime number.

Use differentials to estimate the amount of paint needed to apply a coat of paint 0.07 cm thick to a hemispherical dome with dia
Mademuasel [1]

An hemispherical dome is half a sphere. If the diameter is 60 m, then the radius is 30 m.

We can use differentials to solve this problem because we are adding a thin layer to the original dome, so the volume of the dome in increased by a differential of itself.

This differential volume that the dome is increased is equal to the volume of the coat of paint.

The volume of the dome can be written as:

\begin{gathered} V=\frac{4\pi}{3}r^3 \\ \frac{dV}{dr}=\frac{4\pi}{3}\cdot3r^2\Rightarrow dV=\frac{4\pi}{3}\cdot3r^2\cdot dr=4\pi r^2\cdot dr \end{gathered}

Now, we can calculate dV as:

\begin{gathered} dV=4\pi r^2\cdot dr \\ dV\approx4\cdot3.14\cdot(30m)^2\cdot0.07\operatorname{cm}\cdot\frac{1m}{100\operatorname{cm}} \\ dV\approx12.57\cdot900m^2\cdot0.0007m \\ dV\approx7.92m^3 \end{gathered}

Answer: the paint needed for this coat is approximately 7.92 m^3

Solve the inequality −x/2&lt;4
FinnZ [79.3K]

Isolate the x. First, multiply 2 to both sides

-x/2(2) < 4(2)

-x < 4(2)

-x < 8

Isolate the x. Divide - 1 to both sides (because you are dividing a negative number, flip the sign).

-x/ -1 < 8/-1

x > -8 is your answer

hope this helps
