Answer: 4

Step-by-step explanation: there is 4 quarts in a gallon so 1/2 gallon is 2 quarts. 2x2=4

Answer:

6 gallons which is 24 quarts

Step-by-step explanation:

because while covering 2/12ths of a wall you used a whole gallon of paint so if 1 gallon covers 2/12ths of a wall you have 10/12ths left and s you already used 1 so it  would leave you with 5 gallons and 10 divided by 2 is 5 which would give you your answer  6 gallons and there are 4 quarts in a gallon so you would multiply 6 *4 = 24

Answer:

120

Step-by-step explanation:

A hexagon has six sides, and we can use the formula degrees = (# of sides – 2) * 180. Then degrees = (6 – 2) * 180 = 720 degrees. Each angle is 720/6 = 120 degrees.

Answer:

20 minutes per row

Step-by-step explanation:

Divide the total time by the total number of rows to find the amount of time for one row

6r= 120

Divide each side by 6 to isolate the variable (r= number of rows)

r= 20

Answer:

y = 1/6x - 8/3

Step-by-step explanation:

The equation of a line in slope-intercept form is.

y = mx + b

where m represents the slope and b, the y-intercept.

Rearrange y + 2 = 1/6 (x - 4)  into this form

distribute bracket and simplify.

y + 2 = 1/6x - 2/3

⇒ y = 1/6x - 2/3 - 2

⇒ y = 1/6x - 8/3 ← in slope-intercept form

Answer:

The exact rotation in revolutions per minute is 1.125 revolutions per minute

[tex]\omega = 1.125 \ \dfrac{Revolution}{minute}[/tex]

Step-by-step explanation:

The given angular velocity is expressed as follows;

[tex]\omega = 135 \cdot \pi \ \dfrac{rad}{h}[/tex]

Therefore, we have;

[tex]\omega = \dfrac{135 }{60} \cdot \pi \ \dfrac{rad}{minute} = \dfrac{9}{4} \cdot \pi \ \dfrac{rad}{minute} = 2.25 \cdot \pi \ \dfrac{rad}{minute}[/tex]

One (1) revolution = 2·π radian

Therefore;

π radian =  1/2 revolution

2.25·π radian = 2.25 × 1/2 revolution = 1.125 revolution

Which gives;

[tex]2.25 \cdot \pi \cdot \dfrac{rad}{minute} = 1.125 \ \dfrac{Revolution}{minute}[/tex]

The exact rotations in revolutions per minute is 1.125 revolutions per minute.

Answer:

The caterer charged $50 for an adult's meal and $13 for a child's meal

Step-by-step explanation:

Let the cost of an adult meal be $x

and the cost of a child meal be $y

From the question,

Manny plans to have 66 adults and 27 children and the total cost of his meals is $3,651.

We can write that

66x + 27y = 3651 ...... (1)

Also, from the question,

Zack has 77 adults and 43 children and the total cost he will pay the caterer is $4,409.

We can also write that

77x + 43y = 4409 ...... (2)

Multiply equation (1) by 7, so that we get

462x + 189y = 25557 ...... (3)

Multiply equation (2) by 6, so that

462x + 258y = 26454 ...... (4)

Now, subtract equation (3) from equation (4), so that

69y = 897

∴ y = 897/69

y = 13

Put the value of y into equation (1) to get x

66x + 27y = 3651

∴ 66x + 27(13) = 3651

66x + 351 = 3651

66x = 3651 - 351

66x = 3300

x = 3300/66

x = 50

Therefore,

The cost of an adult's meal is $50

and the cost of a child's meal is $13

Hence, the caterer charged $50 for an adult's meal and $13 for a child's meal.

Answer:

n= -10

Step-by-step explanation:

-66=7n+4

-7n=4+66

-7n=70

n=70/-7

n= -10

Answer:

n = -10

Step-by-step explanation:

-66 = -9n + 16n + 4

1. I started by subtracting 4 on both sides of the equation this gives you -70 = -9n + 16n

2. I then combined the like terms 16n and -9n on the right side of the equation. We do this by subtracting 9n from 16n. Which gives you -70 = 7n

3. We then divide both sides by 7 in order to get -10 = n

This gives you your final answer of n = -10

Answer:

D) (-5, - 7)

Step-by-step explanation:

Because both lines intersect, they must share a point (have same x and y coordinates).

[tex]2x + 3 = - 4x - 27[/tex]

[tex]2x = - 4x - 30[/tex]

[tex]6x = - 30[/tex]

[tex]x = - 5[/tex]

Substite x for - 5 in any of the equations to find the y coordinate.

[tex]y = 2( - 5) + 3 [/tex]

[tex]y = - 10 + 3[/tex]

[tex]y = - 7[/tex]

The x coordinate for the intersection point is - 5 and the y coordinate is - 7. The intersection point is (-5, - 7)

The Answer is D

Step-by-step explanation:

one time charge of $30

plus $19.99 per hour

let x be the number of hour

and y be the total charge of the magician.

therefore, the equation would be:

y = 19.99x + 30

Answer:

The first one

Step-by-step explanation:

If you are adding 15 less to 3 of n, it would be 3n-15 because 3 of n is 3n. After, you add n as well, so you get 3n-15+n. Your result is 101 so it should be on the other side of the equation.

n = 35

Step-by-step explanation:

n - 13 x -2 = -44

distribute:

(n x -2) - (13 x -2) = -44

-2n - (-26) = -44

two negatives in front of a number makes it a positive number

so rewrite -2n + 26 = -44

-2n = -44 -26

-2n = -70

n = [tex]\frac{-70}{-2}[/tex]

n = 35

Answer:

Total number of fan = 80,495

Step-by-step explanation:

Given:

Number of fans attended = 77,098

Additional number of fans attended = 3,397

Find:

Total number of fan

Computation:

Total number of fan = Number of fans attended + Additional number of fans attended

Total number of fan = 77,098 + 3,397

Total number of fan = 80,495

Most thermal conductors are made up of metal material.

We have to determine, most thermal conductors are made of which material?

According to the question,

It is one of the three concepts by which heat and energy can be transferred from one place to the other within a material or from one material to another.

Conduction occurs by direct contact whereas Convection occurs by movement or flow of heat.

Radiation on the other hand occurs with the help of electromagnetic waves.

Conduction mostly occurs in metals and the conductivity of metal is different from one another.

When it comes to the best metal for thermal conductivity, ideally it is Silver but Copper is used instead.

The reason for it is that Silver is too expensive and is infeasible to use. Copper, on the other hand, is available in abundance, is affordable, and can be used in any application.

Hence, Most thermal conductors are made up of metal material.
