What is the surface area

Answer:

a

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.

#SPJ6

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!

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:

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.

Hope It Helps! Good Luck.

x = -4, x = 1

Step-by-step explanation:

x^2 + 3x - 4 = 0

4 and -1 add to 3 and multiply to -4.

(x+4)(x-1) = 0

Separate these by the Zero Product Property.

x+4 = 0

x-1 = 0

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:

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

Answer:

n =7

the amount is 16,000,000

Step-by-step explanation:

[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]

[tex]So Y=16,000,000[/tex]

so the amount you are looking for is 16,000,000

Answer:The team failed to win 6 games.

Step-by-step explanation: 5/6 has to be equal to something over 36. Since you multiplied the denominator by 6 you have to multiply the numerator by 6 and 5*6 equals 30. If out of 36 games they won 30. Then to find how many games they lost all that you have to do is subtract 36 and 30 to get 6.
