Answer:

V = 262’144 ft^3, surface area = 24’576 ft^2

Step-by-step explanation:

The volume con be find with this formula =

V = side^3

V = 64^3 = 262’144 ft^3

For find the surface area we can proceed in this way: first of all we can find the area of a face.

A = side^2 = 4096 ft^2

a cube has 6 faces, so we have to the mutiply the value six times.

Surface area = 4096  x 6 = 24’576 ft^2

(1)  Equivalent fractions (2) common denominator

Solution:

1. Equivalent fractions name the same amount.

Equivalent fractions are the same value with different numerator and denominator.

Example:

These values are same.

2. A common denominator is a common multiple of two or more denominators.

Example:

Here 6 is a common multiple of 2 and 3.

Hence the answer is (1)  Equivalent fractions (2) common denominator.

Answer:

(6,-5)

Step-by-step explanation:

Answer:

The slope equals the rise divided by the run: . You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope.

Answer:

1/2

Step-by-step explanation:

There are 12 equally likely outcomes.

There are 6 numbers greater than 6 (7, 8, 9, 10, 11, 12)

Take the number of possible outcomes and divide it by the total number of outcomes.  6/12 is 1/2

Answer:

260

Step-by-step explanation:

you would divide 52/200 because all the numbers added up is 200 and it comes out to 0.26 and the original number of students they wanted is 1,000 so look at those zeros and move the decimal 3 times and add the zero in the empty space to get 260.

A ratio shows us the number of times a number contains another number. The number of students the cafeteria should expect to buy pizza is 260.

A ratio shows us the number of times a number contains another number.

The ratio of the number of students to the number of total students can be written as,

Ratio = (Number of students)/(Number of total students)

Ratio = 52/(52+26+30+48+44) = 52/200

Now, the same ratio is applicable to 1000 students, therefore, the ratio will be,

Number of students who prefer pizza = 1000 × (52/200) = 260

Hence, the number of students the cafeteria should expect to buy pizza is 260.

Answer:

x = -3

Step-by-step explanation:

1. Write the equation

3x + 7 = -2

2. -7 from both sides

3x = -9

3. Divide 3 from both sides to get x alone

x = -3

Answer:

Hello There!!

Step-by-step explanation:

3x+7=-2 (-7 from both sides)

-7 -7

3x=-9 (divide by 3 from both sides)

Answer:

[tex](x,y) = (3,1)[/tex]

Step-by-step explanation:

Given

[tex]y < -x + 4[/tex]

[tex]y > 3x - 8[/tex]

Required

Solve graphically

See attachment for graph;

The blue shade represents [tex]y < -x + 4[/tex]

While the green, represents [tex]y > 3x - 8[/tex]

Next, determine the intersection points between the two lines

From the attached graph, we have:

[tex](x,y) = (3,1)[/tex]

Hence, the solution is: [tex](3,1)[/tex]

Answer:

91%

Step-by-step explanation:

The discount is $73 so we would get 73/80.

73/80 is also known as 73÷80

which would equal 0.9125

if we were to covert and round it to a percent, it would be 91%

Answer:

[tex]y = \frac{1}{2}x - 4[/tex]

Step-by-step explanation:

Given

[tex]y = \frac{1}{2}x[/tex]

Required

Shift [tex]3\ units[/tex] down and [tex]2\ units[/tex] right

[tex]y = \frac{1}{2}x[/tex]

Shift 3 units down

The rule is: (x,y)=> (x,y-a)

Where a is the number of units shifted down

In this case: [tex]a = 3[/tex]

So, we have:

[tex]y = \frac{1}{2}x[/tex] == > [tex]y = \frac{1}{2}x - 3[/tex]

Shift 2 units right

The rule is: (x,y)=>(x-b,y)

Where b is the number of units shifted right

In this case: [tex]b = 2[/tex]

So, we have:

[tex]y = \frac{1}{2}x - 3[/tex] ==> [tex]y = \frac{1}{2}(x - 2) - 3[/tex]

Open bracket:

[tex]y = \frac{1}{2}x - 1 - 3[/tex]

[tex]y = \frac{1}{2}x - 4[/tex]

Hence, the new equation after the transformation is:

[tex]y = \frac{1}{2}x - 4[/tex]

Answer:

y = 5

Step-by-step explanation:

40 = 8y

divide both sides by 8, isolating y by itself:

40/8 = 8y/8

5 = y

rearrange the equation so the y is on the left side

y = 5

The answer is y = 5

We can check by plugging in y = 5 into the original equation:

40 = 8y

40 = 8(5)

40 = 40

correct
