Answer: Option C and D

Step-by-step explanation:

Due to the fact both tables are variants of the numbers in the columns.

C - (3,1) 3 = 1 / (9,3) 9 = 3 / (12,4) 12 = 4

[3, 9, and 12 are variants of 3 and 4 by multiplication of 3]

And same goes for D but in that tense the larger numeral is on the bottom.

C and D

Step-by-step explanation:

Answer: Surface Area = 2 x (5x2 + 3x2 + 5x3) = 62 centimeters

Surface area of a right rectangular prism = 2(lh + wh + lw)

Step 1: Label the Given-

Length (l) = 5cm,      Width (w) = 3cm,      Height (h) = 2cm

Step 2: Replace the given-

Surface Area = 2 x (5x2 + 3x2 + 5x3)

= 2 x (31)

Surface Area = 62 centimeters

Horus got his answer, by applying only what lays inside the parentheses. To get the right answer, Horus must multiply what they got by 2:

2 x (31) = 62 centimeters

Answer:

SA= 15+6+10+10+15+6 = 62

Step-by-step explanation:

take your top rectangle multiply length and width= 15

Take the one right below it take the 2cm, and multiply it with 3=6

after that one doe 3x5 again=15

Then, 3x2=6

And then 5x2=10

And then once more=10

Answer:

\((4.9 \times {10}^{8} ) - (2.39 \times {10}^{8} ) \\ =( 4.9 - 2.39) \times {10}^{8} \\ = (2.51 \times {10}^{8} )\)

Hope this will help...

Answer:

2.51 x \(10^{8}\)

Step-by-step explanation:

This is the answer because:

1) All we have to do is subtract 4.9 and 2.39

4.9 - 2.39 = 4.90 - 2.39 = 2.51

2) Next, we just multiply 2.51 with \(10^{8}\) which leave us with 2.51 x \(10^{8}\)

Answer:

3, 16, 17, 18, 19, 20, 21, 22, 23, 24, 24, 25, 26, 27, 28, 29, 30, 31, 32, and 45

Step-by-step explanation:

3, 16, 17, 18, 19, 20, 21, 22, 23, 24, 24, 25, 26, 27, 28, 29, 30, 31, 32, and 45.

Explanation:

There are 20 numbers in the set. Since this is an even number of items, the median will be found as the result of averaging the two values in the center of the set. To ensure the median comes out to be 24, we can either have both numbers be 24, or we can choose two numbers that average to 24 (such as 23 and 25).

The range is the difference between the highest and lowest value. To be 42 requires that

max

−

min

= 42.

The mean of the 20 numbers should come out to roughly 24. This means that the sum of the 20 numbers should be roughly 20*24 = 480.

If we use 24 and 24 as the innermost numbers, that leaves about 480 - 24 - 24 = 432 left for 18 numbers. We can "space out" the min and max around a center of 24 by using the values 3 and 45 (which places each half of the range above and below). That leaves 432 - 3 - 45 = 384 for 16 numbers.

As it turns out, 384 is perfectly divisible by 16, resulting in 24. It would be nice if we could say all 16 numbers are 24, but we're told that no more than 3 numbers are the same. Thus, we can simply space out the numbers in pairs around 24:

23 and 25, 22 and 26, 21 and 27, 20 and 28, 19 and 29, 18 and 30, 17 and 31, and 16 and 32.

Answer:

27

Step-by-step explanation:

24+31+42+18+20=135

135/5=27

To find the mean of a group of numbers you need to + them together then ÷  them by the amount of numbers there are.

Answer: 1/2, 0.51, 11/20

Step-by-step explanation:

Use 100 as a common denominator so you can compare all the numbers in like terms:

1/2 = 50/100

0.51 = 51/100

11/20 = 55/100

Answer:

\(\frac{1}{2} 0.51, \frac{11}{20}\)

Step-by-step explanation:

First, you want to change the decimal into a fraction.  0.51= \(\frac{51}{100}\)

Then, find the common denominator.  In my example, I used 100.  Find the equivalent fraction for the fractions with 100 as their denominator

\(\frac{11}{20} = \frac{55}{100} \\\\\ \frac{1}{2} = \frac{50}{100}\)

Next, line them up in order of their numerators

\(\frac{50}{100} \frac{51}{100} \frac{55}{100}\)

Finally, match the new fraction with their reduced fraction or decimal:

\(\frac{1}{2} = \frac{50}{100} \\\\0.51 = \frac{51}{100} \\\\\frac{11}{20} = \frac{55}{100}\)

Therefore, the answer is 110

If you are using a calculator, simply enter 275÷100×40 which will give you 110 as the answer.

Answer: 29

Step-by-step explanation:

\(58*\frac{4}{8} =\frac{58*4}{8} =\frac{232}{8} =29\)

\(\boldsymbol{\sf{58*\dfrac{4}{8} }}\)

We reduce the fraction 4/8 to its lowest expression by extracting and canceling 4.

\(\boldsymbol{\sf{\dfrac{4}{8}=\dfrac{4\div4}{8\div2}=\dfrac{1}{2} }}\)

           \(\boldsymbol{\sf{58\times\left(\dfrac{1}{2}\right) }}\)

Multiply 58 and 1/2, so 58/2.

                   \(\boldsymbol{\sf{\dfrac{58}{2}= }}\boxed{\bf{29}}\)

Answer:

Step-by-step explanation:

The most common number of hours volunteered is 34, so the answer can't be A or D. 7 students volunteered more than 30 hours, while 12 students did less than 30 hours, which means B is incorrect. There are 3 students that volunteered more than 40 hours and 6 that volunteered between 9 and 20 hours, which means C is correct.

Step-by-step explanation:

The equivalent expression for \([(1.3)^{3} /{(1.2)^{2}}^{4} ]^{-6}\)is \([(1.2)^{2}] ^{24}/(1.3)^{18}\).

Given an expression \([(1.3)^{3} /{(1.2)^{2}}^{4} ]^{-6}\).

We are required to find the equivalent expression of the given expression.

Expression is combination of numbers, fraction,symbols, coefficients, determinants, indeterminants or algebraic operations.  It shows some relationship also. It is found without equal to form.

Expression is \([(1.3)^{3} /{(1.2)^{2}}^{4} ]^{-6}\)

It is in fraction as we know that fraction is combination of two numbers one is numerator and denominator.

First we need to multiply the powers present in numerator and denominator.

=\((1.3)^{-18} /[{(1.2)^{2}}^{-24} ]\)

We have to invert the numerator and denominator because the powers in negative.

=\([(1.2)^{2}]^{24} /(1.3)^{18}\)

Hence the equivalent expression for \([(1.3)^{3} /{(1.2)^{2}}^{4} ]^{-6}\)is \([(1.2)^{2}] ^{24}/(1.3)^{18}\).

By proportion that is:(54/150) * 8450= 54 * 56 1/3= 3042

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

We can solve for H by isolating it on one side of the equation, as follows:

J/H - I/H = G

Taking H as the common denominator:

(J - I)/H = G

Multiplying both sides by H:

J - I = GH

Adding I to both sides:

J = GH + I

Dividing both sides by G:

H = (J - I)/G

So the answer is

(A)

H = (J - I)/G.

Answer:   A

Step-by-step explanation:

\(\frac{J}{H} = G + \frac{I}{H}\)                >Since you are solving for H bring I/H to the other side

                                   by subtracting I/H from both sides

\(\frac{J}{H}- \frac{I}{H} = G\)               >There is a common denominator so you can

                                   combine the fractions

\(\frac{J-I}{H} = G\)                   >Multiply both sides by H or cross multiply whichever

                                  way your mind things about how to get H on top

\(J-I = G(H)\)           >Divide both sides by G

\(\frac{J-I}{G} = H\)                   >Answer is A

To solve each compound inequality, we can break it into two separate inequalities and solve each one separately.

For the first compound inequality, f-4<5 and f-4 ≥ 2, we can break it into two separate inequalities: f-4<5 and f-4>2. Solving these inequalities separately, we get:

f-4<5

f<9

f-4>2

f>6

Therefore, the solution to the compound inequality is 6<f<9.

For the second compound inequality, y-1 ≥7 or y+3<-1, we can break it into two separate inequalities: y-1>=7 and y+3<-1. Solving these inequalities separately, we get:

y-1>=7

y>=8

y+3<-1

y<-4

Therefore, the solution to the compound inequality is y<-4 or y>=8.

For the third compound inequality, -5<3p+7≤22, we can break it into two separate inequalities: -5<3p+7 and 3p+7≤22. Solving these inequalities separately, we get:

-5<3p+7

3p>-12

p>-4

3p+7≤22

3p≤15

p≤5

Therefore, the solution to the compound inequality is -4<p≤5.
