Please Help me solve this (Who ever answers correctly will get brainlest)

Answer:

It is A

Step-by-step explanation:

Cuz it rotates Over the axis and reflect over it

Answers:

1.) C and F - I simply found the volume of all of the prisms.

2.) 210 cubic cm - I multiplied 5x6x7 and got a volume of 210 cubic cm.

3.) C.) Volume - You were given the length, width, and height.

4.) B, C, E

5.) C, D, E

6.) A, C, E - I multiplied everything to see what match the volume of 240.

7.) 400 cubic inches - Multiply them all.

8.) 180 cubic feet - 8x3x5 + 4x5x3

9.) A.) Length A- 5ft  Width B- 4ft B.) 104 cubic feet

10.) 300 cubic inches - 8x3x5 + 12x3x5

Side note:

Volume is calculated by multiplying length, width, and height. Your work should be multiplying those. Ask me any questions! Brainliest would be greatly appreciated.

I hope this helped!

Good luck <3

Answer:

[tex]7*(10-7)[/tex]

[tex]7*3[/tex]

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:

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:

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:

72

Step-by-step explanation:

3 (20 + 4)

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

= 60 + 12

= 72

Hope it helps ⚜

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:

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:

18 eggs

Step-by-step explanation:

4 7/12 - 3 1/2

= 1 6/12 or 1 and 1/2

* 12 and you get 12 and 6 eggs

12+6 = 18

Answer:

The ratio of losses to wins is 6:9 or if simplified 3:2

Step-by-step explanation:

The 7th grade basketball team played 15 games in total. If they had 9 out of those 15 games they lost the other 6. So, the ratio of losses to wins is 6:9. Losses goes first because its first in the word problem. To simplify a ratio find the number they both divide into. In this case its 3. 6 divided by 3 is 2. And 9 divided by 3 is 3. So in simplest form the answer is 3:2 :)

Answer:

9/4

Step-by-step explanation:

Answer:

3-  Answer is D or 35

4- Answer is B 5,9,6

Step-by-step explanation:

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:

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:

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".

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

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

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.
