Hope this Helps!!

6 boxes

24x3=72

72/12=6

Answer: 3.6 cups or 3  3/5 cups

Step-by-step explanation: what i would do here is set up a proportion. Change 3/4c to .75 cups as it’s easier to place in a proportion (and less confusing).. cross multiply .... (.75 x 48= 36) then divide 36 by 10 and that will give you x

Solve for y. Note the equal sign. What you do to one side, you do to the other. Isolate the y. Do the opposite of PEMDAS.

First, subtract x from both sides

y²z + x (-x) = b (-x)

y²z = b - x

Next, divide z from both sides

(y²z)/z = (b - x)/z

y² = (b - x)/z

Finally, to fully isolate the x, root both sides

√(y²) = √((b - x)/z)

y = √((b - x)/z)

y = √((b - x)/z) is your answer

The given speed is = 8.8 meter per second

To convert it in kilometer per hour, we will do the following steps:

1 meter = 0.001 km

So, 8.8 meter = 0.0088 km  

3600 seconds = 1 hour

1 sec = [tex]\frac{1}{3600}[/tex] hours

now, [tex]\frac{8.8meter}{second} = \frac{0.0088}{\frac{1}{3600} }[/tex]

Now multiplying 0.0088 and 3600

[tex]0.0088*3600[/tex]

= 31.68 km/h

2x + y - 6 = 0

given 2x + y = 6 ( subtract 6 from both sides )

2x + y - 6 = 0 ← in general form

Answer:

Option B

Step-by-step explanation:

We have to write the equation in the general form

Ax + By + c = 0

Equation is 2x + y = 6

We subtract 6 on both the sides of the equation to convert in the standard form.

2x + y - 6 = 6 - 6

2x + y - 6 = 0

where A = 2

           b = 1

and    c = (-6)

Option B will be the answer.

2. The domain is [0,2.121...]. The range is from 0 to the max height. The d for which the ball is the highest is given by the formula x = -b / 2a = -3.3/(-3.2) = 1.031... so the max is 1.902... So the range is [0,1.902...] So the answer is C.

Yes this is an exponential function. One way we can determine this is to notice how each y term is multiplied by 6 to get the next y term

example: -2 times 6 = -12

another example: -12 times 6 = -72

The exponential function that models this data is y = -2*6^(x-1). Note how plugging in  x = 1 leads to y = -2. Plugging in  x = 2 leads to y = -12, and so on.

To find the answer you must divide both variables.

315/45 = 7

It will take 7 Hours to drive 315 Miles.

For these types of problems, there is a shortcut to eliminating an answer choice, look at the Y intercepts in the different choices and compare that to the graph.  In this case, you can eliminate A, because the line crosses at y=-2.

Now start at -2 on the y intercept and see which answer choice will make you hit another point on the line.

B can be eliminated because because you rise 3 and run 2, since you run a positive number, that means you move to the right, so that will eliminate that answer, but lead you to the correct one.  You can tell that rising positive 3 was correct, but now you have to move to the left so that would be a negative and you have to move 2 spaces.

So combining those two thoughts, -3/2 is what you would be looking for making D your answer.

Answer:

The square-root of a number has 2 same factors being multiplied to get that number while a cubic-root of a number has 3 same factors being multiplied to get that number. For example, the square-root of 64 is 8 because 8 x 8 is 64. However, the cubic-root of 64 is 4 since 4 x 4 = 16 x 4 = 64.

Step-by-step explanation:

Finding the square-root of a number means finding two same numbers that when multiplied equal one number, while finding the cubic-root of a number means finding three same numbers that when multiplied equal one number. For example, the square-root of 64 is 8 because 8 x 8 is 64. However, the cubic-root of 64 is 4 since 4 x 4 = 16 x 4 = 64.

The square root of a number is found by multiplying it by itself, while the cube root is found by multiplying it by itself three times.

Finding the square root of a number is the process of finding a number that when multiplied by itself gives the original number. For example, the square root of 64 is 8, because 8 x 8 = 64.

Finding the cube root of a number is the process of finding a number that when multiplied by itself three times gives the original number. For example, the cube root of 64 is 4, because 4 x 4 x 4 = 64.

So, the main difference is that the square root involves multiplying a number by itself once, while the cube root involves multiplying a number by itself three times.

Arrays are useful representations of multiplication concepts of the commutative property.

We need to find how can you use an array to show the commutative property.

The word 'commutative' originates from the word 'commute', which means to move around. Hence, the commutative property deals with moving the numbers around. So mathematically, if changing the order of the operands does not change the result of the arithmetic operation then that particular arithmetic operation is commutative.

An arrangement of objects, pictures, or numbers in rows and columns is called an array. Arrays are useful representations of multiplication concepts (among other ideas in mathematics).

The commutative property of multiplication can be neatly illustrated using an array. For example, the array above could be read as 2 rows of 6, or as 6 columns of 2. Or the array could be physically turned around to show that 2 rows of 6 have the same number as 6 rows of 2.

Therefore, arrays are useful representations of multiplication concepts of the commutative property.

So you need to see how many times they get paid in a year. 12 months ÷ by every 3= 4. So then you multiply the $25 by 4. Which equals $100.

Final answer:

Michael will earn $100 in one year by washing the Gomez family's cars, as he is paid $25 every 3 months and there are 4 three-month periods in a year.

Explanation:

The question involves calculating how much Michael will earn in one year from washing the Gomez family's cars. Since Michael is paid $25 every 3 months, we first determine how many 3-month periods are in one year. There are 4 such periods in a year (12 months ÷ 3 months = 4). Therefore, Michael will earn $25 for each of these 4 periods.

To find the total amount Michael will earn in one year, we multiply the amount he earns every 3 months by the number of 3-month periods in a year:

$25 per period × 4 periods per year = $100 per year

None of the choices you provided are correct.  If you meant to type in ≥ and ≤ instead of > and <, then the first answer is correct.

Answer: D

Step-by-step explanation:

AS we don't know the width so  let consider width=x inches

According to given condition

 length = (3x -5) inches

TV screen is rectangular shaped so

Perimeter= 2( length +width) =2{(3x-5)+ (x)}              equation 1

also given   Perimeter = 150 inches     equation 2

comparing equation 1 &2  

2{(3x-5)+ (x)} =150

2{3x-5+x} =150

2{4x-5} =150

8x-10 =150

Adding 10  both sides

8x -10 +10 =150+10

8x=160

dividing 8 both sides

8x/8= 160/ 8

x= 20 inches    width of screen.

length =( 3x-5) ={3(20) -5}

                       =60-5

             length   =55

If the The length of the flat screen tv is 5 inches less than 3 times it's width, and the perimeter is 150 inches, then the dimension of the TV screen = 55 inches by 20 inches

Let the length of flat screen tv be represented by L

Let the width of the flat screen tv be represented by W

Three times the width of the flat TV screen = 3W

The length of the flat screen tv is 5 inches less than 3 times it's width.

L   =  3W  -  5........................(1)

The TV screen is rectangular in shape

The perimeter of the TV screen is given by the formula:

P   =  2(L  +  W)

The perimeter of the TV is 150 inches

P  =  150 inches

150   =  2(L  +  W)

L  +  W   =  150/2

L   +  W   =  75..........(2)

Substitute equation (1) into equation (2)

3W  -  5  +   W   =   75

Collect like terms

3W  +   W   =  75  +  5

4W   =  80

W   =  80/4

W   =  20

Substitute W = 20 into equation (1)

L  =  3W  -  5

L   =  3(20)  -  5

L  =   60   -  5

L  =  55

The width of the TV screen = 20 inches

The length of the TV screen = 55 inches

The dimension of the TV screen = 55 inches by 20 inches

The number of sides in the regular polygon is 2.

To find the number of sides in a regular polygon, we can use the formula:

Number of sides = 360 degrees/measure of each interior angle

In this case, the measure of one interior angle is given as 144 degrees. Substituting this value in the formula, we get:

Number of sides = 360 degrees/144 degrees = 2.5

Since the number of sides cannot be a decimal, we round down the answer to the nearest whole number. Therefore, the number of sides of the regular polygon is 2.

The number of sides of a regular polygon with each interior angle measuring 144 degrees is 10.

To find n, we can use the formula for the sum of interior angles of a polygon, which is (n-2) times 180 degrees.

Since we know that each angle measures 144 degrees in this regular polygon, we can set up the equation (n-2)times 180 degrees = n times 144 degrees.

Solving for n gives us:

n times 144 degrees = (n-2) times 180 degrees
n times 144 degrees = 180n - 360 degrees
180n - 144n = 360 degrees
36n = 360 degrees
n = 10.
