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:

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:

D) r=5

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.

Answer:

15: Yes, no, yes, yes, no; 16A: C = ($0.29)X + ($1.45)Y + ($2.50)Z; 16B: Yes

Step-by-step explanation:

For question 15: We need to multiply the widths and lengths given to see if they equal the area we are trying to achieve. Therefore, some of them work, and some do not.

For question 16:

Part A: We'll set a variable for the number of each supply she can buy. Pencils will be represented by X, pens by Y and Notebooks by Z, and we'll represent total cost by C. The total cost will therefore be represented by C = ($0.29)X + ($1.45)Y + ($2.50)Z.

Part B: We'll plug the numbers of items she wants to buy into our formula and see if it comes out to less than $20. So in this case C = ($0.29)(3) + ($1.45)(4) + ($2.50)(2). Therefore, C = $11.67, which is less than $20, so she can afford her school supplies.

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).

Answer:

x=16 would be the angle measures.

Answer:

The 2 numbers are 32 and 27.

Step-by-step explanation:

32 plus 27 equals 59.

32 minus 27 equals 3.

So, the answer is 32 and 27.

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

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.

Step-by-step explanation:

Answer:

yes b and d

Step-by-step explanation:

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
