Answer: 61 cents

Step-by-step explanation:

Let’s assume a circle is X and a square is Y.

The problem states:

5x + 1y = 20

2x + 3y = 21

Taking the 1st equation we can see that

1y = 20-5x which is the same as

y = 20–5x

If we replace y in the 2nd equation with the above we get:

2x + 3(20–5x) = 21

which is the same as

2x + 60 - 15x = 21

we can rearrange to get

2x -15x = 21 -60

which is the same as:

-13x = -39

therefore x = -39/-13 or

x = 3

We can then calculate y

If y = 20–5x, then y = 20 -15

There y = 5

So to answer you question, 12 circles plus 5 squares =

12x + 5y = 12(3) + 5(5) = 36 + 25 = 61 cents

Answer:

A function is a rule that assigns to each input exactly one output.

Step-by-step explanation:

If you have more than one of the same inputs for multiple outputs, it would create a vertical line at somepoint on your line.

Answer:

The correct answer is "a rule that assigns to each input exactly one output".

Step-by-step explanation:

In mathematics, a function is a binary relation between two sets that associates to each element of the first set exactly one element of the second set. Typical examples are functions from integers to integers, or from real numbers to real numbers.

Answer:

Sandbars begin forming underwater. As waves break, this pulls material from the shoreline, migrating further into the ocean. During heavy storms, large waves can build sandbars far from shore, until they rise above the water's surface.

Step-by-step explanation:

Water brings sand and other sediment to the surface and creates a strip of land that lays between water.

Answer:

x=16 would be the angle measures.

Answer:

- 1

Step-by-step explanation:

( x + 4 )² + 38 = 47

( x + 4 )² = 47 - 38

( x + 4 )² = 9

( x + 4 )² = 3²

Square root on both sides,

x + 4 = 3

x = 3 - 4

x = - 1

Answer:

Step-by-step explanation:

Given,

Point A = 2,3

Point B = -2, -1

So,

X1 = 2, X2 = -2 , Y1 = 3 , Y2 = -1

Therefore,

Distance between Point A and B is

[tex] = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } [/tex]

[tex] = \sqrt{ {( - 2 - 2)}^{2} + {( - 1 - 3)}^{2} } [/tex]

[tex] = \sqrt{ {( - 4)}^{2} + {( - 4)}^{2} } [/tex]

[tex] = \sqrt{16 + 16} [/tex]

[tex] = \sqrt{32} [/tex]

Answer:

7/2 = 35/10

3/5 = 6/10

Step-by-step explanation:

To get a common denominator of 10, simply multiply the current denominator by any number to equal 10. The first fraction has a denominator of 2. If we divide 10 by 2, we get the answer 5. This means 2 can be multiplied by 5 to get a denominator of 10. However, what we do to the denominator we must also do to the numerator (multiply by 5).

7/2

7 × 5 / 2 × 5

35/10

3/5

3 × 2 / 5 × 2

6/10

Answer:

7/2 = 35/10

3/5 = 6/10

Step-by-step explanation:

[tex]\frac{7}{2}\cdot \frac{5}{5}=\frac{35}{10}[/tex]

[tex]\frac{3}{5}\cdot \frac{2}{2}=\frac{6}{10}[/tex]

Answer:

A general linear function can be written as:

y = a*x + b

Where a is the slope and b is the y-intercept (the point at which the line intersects the y-axis).

In this case, we know that the line should intersect the y-axis (the vertical one) at y = 3 (in the point (0, 3))

And the slope is -3, then the equation of the line is:

y = -3*x + 3

To graph this line the general way is to find two points of the line.

So we need to evaluate the function in two different values of x.

In this case, we already know that the line passes through the point (0,3), then we only need to find another point.

To do it, we can just replace the x-value for a value we want, like x = 1

Then the y-value will be:

y = -3*(1) + 3 = -3 + 3 = 0

Then we also have the point (1, 0).

Now that we have two points, we can graph them and draw a line that connects the point, that line is the graph of our linear equation.

An example of this can be seen below.

Answer:

X=3

Step-by-step explanation:

Since all the sides of a square are equal, hence;

5x-2 = x+10

Collect like terms

5x-x = 10+2

4x =12

X = 12/4

X =3

Hence the value of x is 3

Step-by-step explanation:

Any triangle formed with one side of the triangle being the diameter of the circle it’s inscribed in will be a right triangle.

6²+8²=c²

36+64=c²

100=c²

√100=c

c=10

So the diameter is 10.  That makes the radius 5.
