The mad of 1, 10, 7, 6, 4 , 8

Answer:

What I understand is that I need to give someone an exact number so that when 30% is taken, they keep exactly 35,000

To make the statement above true, we would need to divide 35,000 by 7 since the answer would be 10% of the number we need. Once we do this we get 5000 which is 10% now we multiply 5000 by 10 to get 100% and we get 50.000 once we give this amount to the person and 30% is taken away they are left with 35,000

Answer:

Difference of volume of air = [tex]17182.08cm^{3}[/tex]

Step-by-step explanation:

Radius of ball = 18 cm

Volume of big ball = [tex]\frac{3}{4} \pi o^{3}[/tex]

                               = 4/3 x * 14 X 18[tex]^{3}[/tex]

                               = 7324g * g2/ 3

                               = 24416.64cm^3

Radious of another (small ball) = 12 cm

Volume of small ball = [tex]\frac{3}{4} \pi R^{3}[/tex]

                                  = 4/3 x 3 * 14 X 12^3

                                  = 21703.68/ 3

                                  = 7234 * 56cm^3

Difference of volume = [tex]v_{b} -v _{s}[/tex]

                                   = 24416 * 64 -  7234 * 56cm^3

                                   = 17182 * 08 cm^3

Hello!

Let's solve this question by using elimination.

5x + 10y = 7

4x + 8y = 3

Let us solve for "y" first by making our "x" variables cancel each other out.

4(5x + 10y = 7)

-5(4x + 8y = 3)

20x + 40y = 28

-20x -40y = -15

0 = 13

Since both the "x" and "y" variables were canceled out after trying to eliminate one of the variables, we can't find a solution since we now have no variables to solve for, therefore there is no solution.

Answer: No solutions

Answer:

y= -2

Step-by-step explanation:

The line y = -2 is half way between the 2 shapes (there are 3 squares between the line).

If you were to have a mirror and place it down this line, you would be able to see that the shapes are reflected in the exact same place.

I have attached a photo to help demonstrate what y= -2 looks like :)

Hope this helps!

Answer:

y=-1

Step-by-step explanation:

The line of reflection is y = -1

The (2x,2y) column data is: A'=(-2,-6), B'=(-2,2), C'=(10,2) and D'=(10,-6). See the sketch of the (x,y) column and the (2x, 2y) column in the image 5.

The Cartesian graph presents x-axis (horizontal) and y-axis (vertical) that intercept in the origin (0,0). This type of graph is used to plot x and y coordinates.

The points, in the plane, are represented as (x,y).

Hence for your question:

A=(-1,-3) ⇒ -1 is x-coordinate and -3 is y-coordinate.

B=(-1,1) ⇒ -1 is x-coordinate and 1 is y-coordinate.

C=(5,1) ⇒ 5 is x-coordinate and 1 is y-coordinate.

D=(5,-3) ⇒ 5 is x-coordinate and -3 is y-coordinate.

For solving this question, you should plot the given points on a Cartesian graph.

      The result of this step you can see in the image 1.

         The result of this step you can see in the image 2.

         The result of this step you can see in the image 3. Now you see a rectangle.

       Thus, you should multiply x-coordinate and y-coordinate by 2.

       A=(-1,-3) ⇒ A'=(-2,-6)

       B=(-1,1)   ⇒ B'=(-2,2)

       C=(5,1)   ⇒ C'=(10,2)

       D=(5,-3) ⇒ D'=(10,-6)

       The result of this step you can see in the image 4.

         The result of this step you can see in the image 5. Now you see a new red rectangle with dimensions greater than the black rectangle plotted from (x,y) column.

Answer:

Step-by-step explanation:

Angle 5 is opposite to 37 => It's equal to 37.
Angle 6 and 7 are supplementary to angle 5 => They are equal to 180 - 37 = 143 each.

Angle 4 is corresponding to Angle 7, and since the 2 lines are parallel, it's equal to 143.

Angle 1 and 3 is supplementary to Angle 4, so they are equal to 180-143 = 37 each

Angle 2 is opposite to Angle 4, so it's equal to 143.


Answer : Angle 1,3,5 = 37
Angle 2,4,6,7 = 143

The value of c in cents when he bought 3 cakes for c cents and 2 loaves of bread for 2c - 11 cents each is 87 cents.

He buys 3 cakes that cost c cents each.

Therefore,

cost of the 3 cakes = 3c

2 loaves of bread that cost 2c - 11 cents each. Therefore,

cost of the two loaf of bread = 2(2c - 11) = 4c - 22

Hence, the total amount he spends can be represented as follows:

5.87 dollars = 587 cents

Therefore,

3c + 4c - 22  = 587

7c = 587 + 22

7c = 609

c = 609 / 7

c = 87

Answer:

Step-by-step explanation:

V=1/3 πr²h

700 π=1/3 πr²×21

r²=100

r=√100=10 units

Answer:

r = 10

Step-by-step explanation:

Using the formula:

[tex]V = \pi r^{2} \frac{h}{3}[/tex]

We make r the subject to get:

[tex]r = \sqrt{3 \frac{V}{\pi h} }[/tex]

Now we substitute values given and simplify:

r = [tex]\sqrt{3 \frac{700\pi }{21\pi } }[/tex]

We can cancel out pi from top and bottom:

r = [tex]\sqrt{3 \frac{700 }{21 } }[/tex]

We can do 700÷21 = 33.3333333333

Now we have:

Applying the Pythagorean theorem, the length of the altitude is: 7.79 units.

The Pythagorean Theorem is given as: c² = b² + a², where c is the hypotenuse.

An altitude of an equilateral triangle bisects the base of the triangle forming equal segments. Therefore, we would have the following:

c = 9

b = 4.5

Length of altitude = a = ?

Thus:

a = √(c² - b²)

a = √(9² - 4.5²)

a = 7.79 units.

Thus, applying the Pythagorean theorem, the length of the altitude is: 7.79 units.
