**Answer:**

63 dimes

**Step-by-step explanation:**

Set up a system of equations where **d is the number of dimes and q is the number of quarters:**

d + q = 106

0.1d + 0.25q = 17.05

Solve by **elimination** by multiplying the top equation by **-0.25** to eliminate q:

-0.25d - 0.25q = -26.5

0.1d + 0.25q = 17.05

**Add together and solve for d:**

-0.15d = -9.45

**d = 63**

**So, there were 63 dimes in the piggy bank**

Let the two numbers be x and y

Their sum is 20, so we can write

x + y = 20

Their difference is 14, so we can write:

x- y = 14

Adding the two equations, we get:

2x = 34

x = 17

Using the value of x, in first equation, we get:

17 + y = 20

so,

y = 3

Thus the two numbers are 17 and 3.

**So, option a is the correct answer**

Their sum is 20, so we can write

x + y = 20

Their difference is 14, so we can write:

x- y = 14

Adding the two equations, we get:

2x = 34

x = 17

Using the value of x, in first equation, we get:

17 + y = 20

so,

y = 3

Thus the two numbers are 17 and 3.

For this case we have the following system of equations:

x + y = 20

x-y = 14

Where,

x: real number

y: real number

Solving the system we have:

x = 17

y = 3

Therefore, the numbers are:

17 and 3

**Answer:**

**17 and 3**

**option 1**

x + y = 20

x-y = 14

Where,

x: real number

y: real number

Solving the system we have:

x = 17

y = 3

Therefore, the numbers are:

17 and 3

**Answer: *for 8* Yes, It is congruent by SAS.**

**Step-by-step explanation:**

Since we know that LM and NM are congruent, and that angles LMP and NMP are congruent, then all we need to do is prove that MP is congruent to MP, and we can do that by saying that MP is congruent to MP using the reflexive property.

The SAS congruence theorem states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.

The SAS **congruence theorem** states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.

To determine if the given triangles are congruent using the SAS congruence theorem, we need to check if the corresponding sides and the included angles are **congruent**. If they are, we can write a proof.

Unfortunately, you have not provided the information about the sides and angles of the given triangles. Please provide the information so that we can determine if the triangles are congruent using the SAS congruence theorem.

**Answer:**

The height of cone is increasing at a rate 0.102 feet per second.

**Step-by-step explanation:**

We are** given the following** in the question:

Instant height = 5 feet

The height of the cone is always equal to the diameter.

**Volume of cone = **

**Rate of change of volume = **

Putting all the values, we get,

**Thus, the height of cone is increasing at a rate 0.102 feet per second.**
