Find the diameter of a hemisphere with a volume of 4,601.39m3

Mathematics
1 answer:
slava [35]2 years ago

Volume of a hemisphere = 2/3πr³

Use that formula to find the radius first.

4,601.39 = 2/3(3.14)(r)³
4,601.39 = 2.093r³
4,601.39/2.093 = r³
2198.47 = r³
∛2198.47 = r
13 = r

To find the diameter: 

radius * 2 = 13 * 2 = 26

Diameter = 26

Hope this helps :)

If ΔMNO ≅ ΔXYZ, then what corresponding parts are congruent?
8090 [49]

Answer:

∠N and ∠Y

Step-by-step explanation:

When two triangles are congruent then there corresponding parts ( angle or sides ) are also congruent or equal, ( CPCTC )

In triangles MNO and XYZ,

Side MN, NO and OM are corresponding to XY, YZ and ZX respectively,

And, angles M, N and O are corresponding to angles X, Y and Z respectively,

Thus, if ΔMNO ≅ ΔXYZ

By CPCTC,

MN ≅ XY

NO ≅ YZ

OM ≅ ZX

Also, ∠M ≅ ∠X, ∠N ≅ ∠Y and ∠O ≅ ∠Z

Hence, THIRD OPTION is correct.

A researcher in environmental science is conducting a study to investigate the impact of a particular herbicide on fish. He has
Vedmedyk [2.9K]

Answer:

The herbicide has no impact on fish

Step-by-step explanation:

Experimental research includes to divide the concerned group 'fishes' here into 'treatment' & 'control' group, to study impact of a treatment. Hypothesis test the statistical significance of  propositions. Null hypothesis signifies no impact, alternate hypothesis signifies impact.

Let averages enzyme level of treatment & control be Xt & Xc

  • Null Hypothesis [H0] : Xt = Xc, or Xt - Xc = 0
  • Alternate Hypothesis [H1] : Xt ≠ Xc, or Xt - Xc ≠ 0

If hypothesis test suggests that there is no significant difference between treatment & control group enzyme level, so we reject H0 & accept H1. It implies that the herbicide has no significant impact on fishes enzymes.

Jaleel and Lisa are simplifying the expression 2 (x minus 2) + 2 as shown. Jaleel’s Method 2 (x minus 2) + 2 = 2 x minus 4 + 2 =
Art [367]

Answer:

(D)Jaleel's method is correct because 2(x-2)=2x-4.

Step-by-step explanation:

Jaleel and Lisa are simplifying the expression 2(x-2)+2 as shown.

J$aleel's Method: \left\{\begin{array}{ccc}2 (x -2) + 2 \\= 2 x - 4 + 2 \\= 2 x - 2\end{array}\right

L$isa's Method: \left\{\begin{array}{ccc}2 (x-2) + 2 \\= 2 x -2 + 2 \\= 2 x\end{array}\right

We can see that Jaleel's method is correct because:

2(x-2)=2x-4.

When you expand, you must multiply the term outside by all the terms inside the bracket.

The correct option is D.

What are the possible steps involved in solving the equation shown? Select three options.
e-lub [12.9K]

Answer:

Option B, C and D are correct choices.

Step-by-step explanation:

We have been given an equation 3.5+1.2(6.3-7x)=9.38. We are asked to choose the steps that are involved in solving the equation.

Let us solve the equation.

Using distributive property a(b+c)=ab+ac, we will distribute 1.2 to 6.3 and -7x.

3.5+1.2*6.3-1.2*7x=9.38

3.5+7.56-8.4x=9.38

Therefore, option B is the correct choice.

Now, we will combine like terms.

11.06-8.4x=9.38

Therefore, option C is the correct choice.

Now, we will subtract 11.06 from both sides of our equation.

11.06-11.06-8.4x=9.38-11.06

-8.4x=-1.68

Therefore, option D is the correct choice.

Now, to solve for x, we need to divide both sides of our equation by -8.4

\frac{-8.4x}{-8.4}=\frac{-1.68}{-8.4}

x=0.2
