Step-by-step explanation:

1: find common divisor

7

2: factor out that divisor

[tex]7((70/7)-49/7)= 7(10-7)[/tex]

3: simplify

[tex]7*3[/tex]

Answer:

The empty space is a 10

Step-by-step explanation:

7 (10-7)

Multiply 7 by 10 and -7

70 -49

Answer:

  C.  None of the above

Step-by-step explanation:

You want an number line representation of the expression |-2/3 -5/3|.

The expression is evaluated by performing the sum -2/3-5/3, then finding its absolute value. The sum is -7/3, and its absolute value is 7/3.

None of the number line diagrams shows the sum or its absolute value.

__

Additional comment

The sum would be shown by moving from 0 to -2/3, then moving an additional -5/3 to the point -7/3. The absolute value would reflect that across the 0 point to +7/3.

Answer:

See explanation and picture below.

Step-by-step explanation:

When the storm began, there was an inch of snow on the ground.

The time on the graph is the number of hours since the storm began.

At the time the storm began, no time had passed since the storm began, so at the time the storm began, time was zero. At zero time, the snow was 1 inch. That gives you the point (0, 1).

For the next 6 hours, snow fell at a constant rate of 1 inch per hour.

At time 1 hour, there were 2 inches of snow. Point: (1, 2).

At time 2 hours, there were 3 inches of snow. Point (2, 3).

At time 3 hours, there were 4 inches of snow. Point: (3, 4).

At time 4 hours, there were 5 inches of snow. Point (4, 5).

At time 5 hours, there were 6 inches of snow. Point: (5, 6).

At time 6 hours, there were 7 inches of snow. Point (6, 7).

The storm then stopped for 3 hours. That means for the next 3 hours after time 6 hours, the snow stayed at 7 inches.

Points: (7, 7), (8, 7), (9, 7).

Then the storm started up again dropping 3 inches of snow per hour for the next 4 hours.

That gives us the next 4 points, in which the hour goes up one by one, and the snow goes up three by three.

Points: (10, 10), (11, 13), (12, 16), (13, 19).

Now you need to plot all the points in bold above and connect them with line segments.

See the picture below.

Answer:

The answer should be 216 if you are just looking for the volume.

hope i helped

Step-by-step explanation:

In order to find volume, you must first know the formula A*A*A meaning width and length which make base and height in order to find the volume. Since its a cube all sides must be equal and that means all the measurements are the same. So all you must do is get six and times it by six. Then the answer for that must be multiplied again to get your volume.

EX: 6*6*6=216.

Answer:

It is A

Step-by-step explanation:

Cuz it rotates Over the axis and reflect over it

it's should be B

reflection over the x-axis

Answer:

D - Translation

Step-by-step explanation:

The image in the -x and -y looks exactly the same as the image in the -x +y which can only mean that it was the process of "translation".

Answer:

slope: 3 ||   y-intercept: 9.4

Step-by-step explanation:

Given equation:

y - 1 = 3x + 8.4

y = 3x + 8.4 + 1

y = 3x + 9.4

Comparing with the formula of slope intercept form: y = mx +b

                                                  where m is the slope and b is the y-intercept.

So here the slope: 3 and y-intercept is 9.4

Answer:

y = 6x - 5

Slope - 6

Y-Intercept - (-5)

y - 1 = 3x + 8.4

Slope - 3

Y-Intercept - 9.4

Answer:

let's say cells is c and hours are x that means there are 15 cells each hour. the equation for that is c=15x

after 08 hours the cells have multiplied 8 times their original size. meaning that the equation changes to this: c=15x          x=8    c= 15(8)

x equals 8 at that time.. literally

ok the cells have multiplied and now there are 120 cells in total

then after one day the cells have multiplied over 12 times afterwards. now x equals 24. the equation would look a little like this:

c=15x      x=24    c= 15(24)

there are 360 cells now.

Explain in your own words the relationship between x=8 with x=24 in the equation.

Answer:

14.83

Step-by-step explanation:

We can use the Pythagorean theorem to solve the question

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

6^2 + DE ^2 = 16^2

36+ DE ^2 = 256

Subtract 36 from each side

DE ^2 = 256-36

DE ^2 = 220

Taking the square root of each side

sqrt( DE^2) = sqrt(160)

DE =14.83239697

Rounding to the nearest hundredth

DE =14.83

Answer:

she will need about

7 and 1/3 cups of flour

Step-by-step explanation:

1 3/4+ 3 2/3 +1 7/8= 7.29 rounded off would be about 7 1/3 cups of flour

Answer:

Step-by-step explanation:

( a ). If input is 2  

2 × [tex]\frac{3}{4}[/tex] ÷ [tex]\frac{2}{3}[/tex] = [tex]\frac{3}{2}[/tex] × [tex]\frac{3}{2}[/tex] = [tex]\frac{9}{4}[/tex] = 2.25

If input is 2, then output is [tex]2\frac{1}{4}[/tex]

( b ). If output is 1/2

x × [tex]\frac{3}{4}[/tex] ÷ [tex]\frac{2}{3}[/tex] = [tex]\frac{1}{2}[/tex]

[tex]\frac{9}{8}[/tex] x = [tex]\frac{1}{2}[/tex]

x = [tex]\frac{1}{2}[/tex] ÷ [tex]\frac{9}{8}[/tex] = [tex]\frac{4}{9}[/tex]

If output is [tex]\frac{1}{2}[/tex] , then input is [tex]\frac{4}{9}[/tex]

Answer:

Step-by-step explanation:

a) input is 2

2 * 3/4 = 6/4

(6/4) / (2/3) = 18/8 or 2.25

b) output is 1/2 (this time we go backwards)

if it is multiply we divide and if it is divide we multiply

1/2 * (2/3) = 2/6        (it said divide by 2/3 so we multiply)

(2/6) / (3/4) = 8/18 or 4/9        (it said multiply by 3/4 so we divide)

Answer:

12

Step-by-step explanation:

Find the mean, you need to add up all the numbers and divide by how many there are.

Woodborough ages total 320, so divide that by 20 entries is mean of 16.

Parkville ages total 560, divided by 20 is a mean of 28.

28-16=12

you can solve this using pythagoras theorem which states that the sum of the square of the lengths of the sides adjacent to the right angle is equal to the square of the length of ypotenuse (hypotenuse is the longest side which is opposite to right angle)

( the attached image will help you understand the theorem better)

so

20² + 15² = x²

400 + 225 = x²

625 = x²

√625 = x

25 = x

Answer:

72

Step-by-step explanation:

3 (20 + 4)

= (3*20) + (3*4)

= 60 + 12

= 72

Answer:

Translation is when you move a shape on a coordinate plane.

Reflection is when the shape is flipped from one axis to the other, can be x or y.

Rotation is when the shape is rotated on the coordinate plane.

Plot an open hole at -6; shade to the right

The open hole is because we don't include -6 itself.

The shading to the right indicates all numbers larger than -6.

Answer:

mark an open dot on -6 then make a line going to the right

Step-by-step explanation:

if the inequality sign is facing the variable (x) then the values will get bigger.

So the direction of the line will go to the right because the values are getting bigger going to the right
