Step-by-step explanation:

one third of 12 is 4 subtracting that from 12 remaining is 8

Answer:

16/15

Step-by-step explanation:

Ratio: 3/4 : 4/5

Whole number ratio: 15 : 16

You need to divide both sides by 15 so you can turn 15 to 1

Divide both sides of the ratio by 15: 1 : 16/15

So, for 1 pound of flour, you need 16/15 pounds of brown sugar for a cake.

Answer: The answer is choice B, C, and D

Step-by-step explanation:

Substitute the largest number in every set to see if it is a solution to the inequality.

The like terms to 4/5 in the group 2 are given as follows:

D. -0.1.

F. 12.

Like terms are terms that have the same letter and the same exponent, as thus they can be either added or subtracted to simplify expressions.

The most basic example of like terms are constants, as they can always be added or subtracted.

In group 2, the terms that are constant are the terms -0.1 and 12, hence they are like terms to the fraction 4/5, meaning that the correct options are given by options D and F.

The like terms to -2.1x would be of 3x and also x/3, as they would have the same variable x with exponent 1.

The problem is given by the image presented at the end of the answer.

Answer:

x = -2

Step-by-step explanation:

6(x - 5) = 6x - 30 (multiply everything inside the bracket by 6, which is outside the bracket)

6x - 30 -3x = -36

3x - 30 = -36

    +30    +30

3x = -6

x = -2

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

Answer:

(1.3^9)/(1.3^3)= Last Column: (1.3)^6

(-5/6)^2= First Column: -5^2/6^2

(-5/6)^1: Third Column: -5/6

(1.3)^0: Second Column: 1

Answer:

first row last column, second row first column, third row third column, last row second column

Step-by-step explanation:

first row last column: doing division w/ exponents means you have to subtract the exponents. 9-3=6 and since they have the same base, you don't have to do anything with it, so the answer is the last column.

second row first column: properties show that the square of -5/6 is equal to -5^2/6^2 or 5^2/-6^2. therefore, the answer is the first column.

third row third column: anything to the power of one is itself.

last row second column: anything to the power of zero is one.

Answer:

Step-by-step explanation:

b=8

12x + b should be equivalent to 3(4x -5)

3(4x -5)

3 multiplied by 4x and -5 is

12x + -8

12x + b = 12x + -8,

therefore b = -8.

Answer:

\(\frac{16}{27}\)

Step-by-step explanation:

From the table, we notice that the total number of students is:

\(3+10+8+6=27\)

Then, along the second column of the table, we notice that the number of students who do not have a brother is:

\(10+6=16\)

So, the probability that a randomly chosen student does not have a brother is:

\(\frac{\text{number of students who do not have a brother}}{\text{total number of students}}=\frac{16}{27}\)

Step-by-step explanation:

for number one the answer is 27 x what is given

Answer:

Step-by-step explanation:

You want the number of small cubes painted on 3, 2, 1, and 0 faces if the outside surface of a cube comprised of 27 small cubes is painted. You also want the height of 200 L of water in a tank of 50 cm radius with a 20 cm radius hole in the middle.

The number of cubes painted on 3 faces is the number of corner cubes: 8.

The number of cubes painted on 2 faces is the number of center-edge cubes, 12.

The number of cubes painted on one face is the number of center-face cubes, 6.

The number of cubes with no painted faces is the number of cubes buried inside, 1.

The painting is ...

The total is 27, as it should be.

The area of the base of the part holding water is ...

  π(50² -20²) = π(2500 -400) = 2100π cm²

The height of 200 L of water will be h, where the volume of the figure is ...

  V = Bh

  V = (2100π cm²)h = 200·1000 cm³

  h = 200/(2.1π) cm ≈ 30.3 cm

The height of the water in the tank will be about 30.3 cm.

__

Additional comment

When working with volumes in liters, it is often convenient to work with dimensions in decimeters (dm), where 1 dm = 10 cm. This is because 1 dm³ = 1 L.

Here, the area is π(5² -2²) = 21π dm², so the height is (200 dm³)/(21π dm²) ≈ 3.03 dm = 30.3 cm.

Answer:

The numbers from top to bottom: 20, 8, 0, -8, -20.

Step-by-step explanation:

To solve, we just need to plug in x-values to the equation to get the y-values.

For the first number, -5, we plug it in, so the equation is -4(-5), which equals 20.

For the second number, -2, -4 x -2 = 8.

For the third number, 0, -4 x 0 = 0.

For the fourth number, 2, -4 x 2 = -8.

For the last number, 5, -4 x 5 = -20.

Answer:

Let x = # of hours Sophia spends ironing shirts

Let y = # of hours London spends ironing shirts

Equations: x + y = 11 and 40x + 25y= 365

Step-by-step explanation:

If Sophia and London worked a combined 11 hours, then one of our equations is : x + y = 11

They also note that Sophia and London both ironed 365 shirts, and Sophia irons 40 shirts per hour while London can iron 25 shirts per hour. Our next equation is : 40x + 25y= 365
