Answer:

Wednesday, #3 : 8x + 54

Step-by-step explanation:

First, sorry this the one I really knew fast.

-2 (-6x -9) -4x (x + 9)

12x + 18 - 4x + 36

8x + 54

Answer:

Tuesday, 1: 30 pounds

Tuesday, 2: 40% of the apples

Tuesday, 3: x ( or any variable) + 8

Tuesday, 4: 9a-3b

Step-by-step explanation:

Since she weighs 38% of the normal weight, you multiply the decimal form to the original weight, which is 78. So .38 multiplied by 78 is 29.64, and rounding it to the nearest pound would make it go up to 30.

38%=.38

.38 x 78=29.64

29.64 rounded = 30

If 3/5 of the apples are ripe, that means that 2/5 are not. An easy way to turn this fraction into a percent is to make the number out of 100. Since 5 x 20 is 100, you multiple both the numerator and denominator by 20. 2 x 20 is 40, 5 x 20 is 100, hence 40/100. The numerator will be the percentage.  

5/5-3/5 = 2/5

2/5 x 20/20 = 40/100

40/100 = 40%

The unknown score would become a variable, and since its increasing by 3 it is +8.

Since the perimeter is adding all sides, you'd add all of the equations. The 3a's times 3 would be 9a, and the -b would become -3b.

3a - b + 3a - b + 3a - b

9a - b - b - b

9a - 3b

Answer:

r = 1

Step-by-step explanation:

The equation is,

→ 6r - 1 + 6r = 11

Now the value of r will be,

→ 6r - 1 + 6r = 11

→ 12r = 11 + 1

→ r = 12/12

→ [ r = 1 ]

Hence, the value of r is 1.

Answer:

The answer is 1 r is equal to 1

Step-by-step explanation:

No, I do not agree with Kimaya. The volume of the rectangular prism is 2 inches x 4 inches x 6 inches = 48 cubic inches. To fill the rectangular prism with 2/5-inch cubes, you would need 48 cubic inches / (2/5) cubic inches per cube = 120 cubes. To fill the rectangular prism with 1/5-inch cubes, you would need 48 cubic inches / (1/5) cubic inches per cube = 240 cubes.

So, it takes less 2/5-inch cubes to fill the prism than 1/5-inch cubes.

Another way to think of it is that the larger the cubes, the less number of cubes you need to fill the same volume, as the cubes are larger in size.

We can conclude that exists 211680 ways.

We know that the three research department is have 8, 10, and 7 members.

We choose a delegate and an alternate to represent the department.

First case: department have 8 members.

So, for a delegate, we have 8 options, and for a alternate 7, so a total of

\(8 \times 7 = 56 \ \text{options}\)

Second case: department have 10 members.

So, for a delegate, we have 10 options, and for a alternate 9, so a total of

\(10\times 9 =90 \ \text{options}\)

Third case: department have 7 members.

So, for a delegate, we have 7 options, and for a alternate 6, so a total of

\(7\times6 = 42 \ \text{options}\)

Therefore, we get:

\(56 \times 90 \times 42 = \bold{211680}\)

Hence, we conclude that exists 211680 ways.

Answer:

33

Step-by-step explanation:

A number raised to a power is that number multiplied by itself that many times. 2^3 is equal to 2 x 2 x 2, which is equal to 4 x 2, which is equal to 8. 5^2 is equal to 5 x 5, which is equal to 25. 8 plus 25 is equal to 33.

The baby gorilla grew 340 grams in the first 10 days. This is an average of 34 grams per day. The baby gorilla grew 340 grams in the next 10 days. This is an average of 34 grams per day. The baby gorilla grew at the same rate in the first 10 days and the next 10 days.

Here is the solution:

340 grams / 10 days = 34 grams per day

340 grams / 10 days = 34 grams per day

34 grams per day = 34 grams per day

Therefore, the average number of grams that the baby gorilla grew each day during the first 10 days and during the next 10 days is 34 grams per day.

Answer:

P(-3,0) Q(-3,-5) R(5,-3) S(-3,-11)

Step-by-step explanation:

Remember that 8 units down is -8 to the Y coordinate of each point

And 5 units to the left is -5 units

(5-8, 5-5)=P(-3,0)

(10-5,5-8)= R=(5, -3)

Mean of team A  < Mean of team B

MAD of team A < MAD of team B

Now, We can simplify as,

The double dot plot shows the runs scored per game by two baseball teams during a 10 game seasons.

Now, We can find the value of mean as,

For team A,

Mean = (2 x 1 + 3 x 1 + 4 x 4 + 5x 2 + 6 x 1 + 7 x 1) / 10

Mean = (2 + 3 + 16 + 10 + 6 + 7) / 10

Mean = 44 / 10

Mean = 4.4

For team B;

Mean = (2 x 1 + 5 x 2 + 6 x 4 + 7 x 2 + 9 x 1) / 10

Mean = 59/10

Mean = 5.9

MAD for both team are,

For team A;

MAD = |4.4 - 2| + |4.4 - 3| + 4 |4.4 - 4| + 2 |4.4 - 5| + |4.4 - 6| + |4.4 - 7| / 10

MAD = 2.4 + 1.4 + 1.6 + 1.2 + 1.6 + 2.6 / 10

MAD = 1.08

For team B;

MAD = |5.9 - 2| + 2|5.9 - 5| + 4 |5.9 - 6| + 2 |5.9 - 7| + |5.9 - 9| / 10

MAD = 3.9 + 1.8 + 0.4 + 2.2 + 3.1 / 10

MAD = 1.14

Hence,

Mean of team A  < Mean of team B

MAD of team A < MAD of team B

Answer:

\(16^{3x}= 32^{2(x+2)}\)exponential equation represents this situation

Step-by-step explanation:

Let the number be x

Raising 16 to a power that is 3 times some number=\(16^{3x}\)

Raising 32 to twice the sum of the number and 2 =\(32^{2(x+2)}\)

We are given that Raising 16 to a power that is 3 times some number is the same as raising 32 to twice the sum of the number and 2.

Equation:\(16^{3x}= 32^{2(x+2)}\)

So, The required equation is\(16^{3x}= 32^{2(x+2)}\)

Hence  \(16^{3x}= 32^{2(x+2)}\)exponential equation represents this situation

Answer:

The total area of the back classroom wall is (20ft x 12ft) = 240ft²

The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².

Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.

Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.

Answer: The ratio is 18:3

Step-by-step explanation:

Answer:  6 to 1

Step-by-step explanation:

A ratio refers to a fraction. In this case the question asks how many players to coaches there are.

The word "to" means that is where the fraction bar goes.

Players/Coaches

There are 18 players and 3 coaches.

18/3

18 can be divided by 3, 6 times so the fraction can be simplified to

6/1 meaning there are 6 players for every coach.
