Step-by-step explanation:

CB and GF are the same side and u can see that CB is two times larger than GF so GH is two times smaller then CD

The solution is, the value of GH = 2, option A.

A scale factor is when you enlarge a shape and each side is multiplied by the same number. This number is called the scale factor. Maps use scale factors to represent the distance between two places accurately.

here, we have,

If CB = 6, GF = 3, and CD = 4,

and, we have to find GH.

from the given figures we get,

CB and GF are the same side and u can see that CB is two times larger than GF so GH is two times smaller then CD.

i.e. CB/GF = 6/3 = 2

scale factor = 2.

again, CD/GH = 2

So, GH = CD/2

            =2

Hence, The solution is, the value of GH = 2.

Answer:

volume of a hemisphere ≈ 36369.5 in³

Step-by-step explanation:

To find the formula for calculating the volume of a hemisphere, we will follow the steps below:

write the formula for calculating the volume of a hemisphere.

volume of a hemisphere = volume of a sphere ÷2

                                        = [tex]\frac{4}{3}[/tex]πr³   ÷   2

                                        =[tex]\frac{2}{3}[/tex] πr³

where r is the radius

from the question given, diameter = 51.8 inches

but diameter = 2r , this implies that r = [tex]\frac{d}{2}[/tex]    hence   r = [tex]\frac{51.8}{2}[/tex] = 25.9 inches

π is a constant and is ≈ 3.14

we can now proceed to insert the values into the formula

volume of a hemisphere    =[tex]\frac{2}{3}[/tex] πr³

                                                =[tex]\frac{2}{3}[/tex] × 3.14 ×25.9³

                                                =[tex]\frac{2}{3}[/tex] × 3.14×17373.979

                                                 ≈36369.5 in³ to the nearest tenth cubic inch.

volume of a hemisphere ≈ 36369.5 in³

Answer:

[tex]\dfrac{118}{135}[/tex]

Step-by-step explanation:

Total Number of Students =135

Number who took all three subjects=5

Number who took PE and BIO=10

Number who took PE and ENG=15

Number who took BIO and ENG=7

Therefore:

Total Number of students who took exactly two subjects=5+10+2=17

Therefore:

Number of students who did not take exactly two subjects=135-17=118

The probability that a randomly-chosen student from this group did not take exactly two subjects

[tex]=\dfrac{\text{Number of students who did not take exactly two subjects}}{\text{Total Number of students }} \\=\dfrac{118}{135}[/tex]

Answer:

3 * 10 ^-2

Step-by-step explanation:

When we divide numbers in scientific notation first divide the number portion

2.7 /9 =.3

Then divide the exponents

10 ^5 / 10 ^6 = 10 ^ (5-6) = 10 ^ -1

.3 * 10 ^-1

We cannot leave the .3 since the first number has to be between 1 and less then 10

Move the decimal 1 place to the right which means subtract 1 from the exponent

3 * 10 ^-2

Answer:

0.03

Step-by-step explanation:

Hello there! Lets get started!

Now, with this problem as simple as it is, there are multiple ways we could solve it! If you have a scientific or graphing calculator, you could easily plug it in as it is! If you just have a four-function calculator, you could still solve it! Or, You could get advanced with log functions and such, but that is not needed at all for this function.

I am going to assume that you only have access to a four-function calculator, so lets begin!

First, we need to expand our numerators and denominators beyond scientific notation!

When dealing with positive scientific notation, you are moving your decimal to the right (I am not going to fully explain how to expand scientific notation, we are just going to move the decimal).

With 2.7 x [tex]10^{5}[/tex], we will move the decimal 5 places to the right!

With 9.0x [tex]10^{6}[/tex], we will move the decimal 6 places to the right!

This gives us 270000 and 9000000!

Now lets solve 270000 ÷ 9000000!

This gives us a final answer of .03!

Hope this helps! Remember, math is fun!

Step-by-step explanation:

Answer A is wrong: 5 + 2 + x

Answer C is wrong: 5 + x + x

Answer D is wrong: 5 + x*x

F is wrong, because a product is the result of multiplying.

The statements that describe the expression 5+2x is the E and A is correct.

We have given that,

Answer A is wrong: 5 + 2 + x

B ) The expression represents 5 plus 2 plus x.

5+2x=5+2x

This is a correct statement.

An expression, in math, is a sentence with a minimum of two numbers and at least one math operation in it.

Answer C is wrong: 5 + x + x

Answer D is wrong: 5 + x*x

E The expression represents the sum of 5 and 2x.

5+2x=5+2x

This is the correct statement.

F is wrong because a product is a result of multiplying.

The statements that describe the expression 5+2x is the E and A is correct.

Answer:

the amount is 16,000,000

Step-by-step explanation:

first let that amount be Y for an example. so...

[tex]\frac{5}{100}*Y=800,000[/tex]

[tex]\frac{5Y}{100}=800,000[/tex]

[tex]5Y=800,000*100[/tex]

[tex]5Y=80,000,000 (then you both divide by 5 in both sides so that Y is left alone.)[/tex]

Answer:

Hello There. The correct answer to this is B. Because it shows that A = 4pr2 We need divide each term of 4pr2 = A r2 A-4p Then we need to do is Take the square root of both sides of the equation to eliminate the exponent on the left side. r = + A-4p Then completed of the solution is the result of both the positive and negative portions of the solution.

Answer: 6

Step-by-step explanation: You can make this question into an algebraic expression. This is basically 3.14x(z^2)x15=1696.5.  If you divide 1696.5 with 15, you get 3.14x Z x Z=113.1. If you divide 113.1/3.14, you get about 36, and the square root of 36 is equal to 6.

Answer:

n =7

Step-by-step explanation:

(n+1) +1 + (n-1) = value  first row

3+ (2n-9) +n = value   second row

The value has to be the same

Set the equations equal

(n+1) +1 + (n-1) =3+ (2n-9) +n

Combine like terms

2n+1 = 3n-6

Subtract 2n from each side

2n+1-1 -2n = 3n-6-2n

1 = n-6

Add 6 to each side

1+6 = n-6+6

7 = n
