Lin has 13 coins in her pocket that equal 40 cents. All the coins are dimes, d, and pennies, p. Which combination of coins does Lin have? Use the table to answer the question.

Answers

Answer 1

To answer this question you should begin with the coin that has a higher value. If you start with the dime and then just add the correct number of pennies to total $0.40, you will see that you will need 3 dimes ($0.30) and 10 pennies ($0.10).

I used a guess and check strategy starting with 2 dimes.

Answer 2

Answer:

The combination of coins are:

3 dimes and 10 pennies.

Step-by-step explanation:

Let there are d number of dines and p number of pennies.

Now as there are a total of 13 coins this means that:

d+p=13------(1)

and also the total value of the coins is 40 cents.

1 dime=10 cents

Hence, d dime= 10 d cents

Also, 1 penny= 1 cent

Hence p penny= p cents

Hence, we get:

10d+p=40------(2)

On subtracting equation (1) from (2) we get:

9 d=27

on dividing both side by 9 we get:

d=3

On putting the value of d in equation (1) we get:

3+p=13

i.e. p=13-3

i.e. p=10

The combination is:

3 dimes and 10 pennies

It's 3/5 of the wall is made from brick how do you determine the height of the brick proportion of the wall

Answers

If 3/5 of the height is made of brick, multiply the total height by 3/5 to find the height of the brick portion.

_____
"Of" means "multiplied by", so
(3/5) of the height is brick
means
(3/5)*(the height) = height of brick portion

To find the height of the brick proportion of a wall, multiply the total wall height by the fraction representing the brick portion. For instance, if the wall is 220 cm high and 3/5 is brick, the brick portion's height would be 132 cm.

To determine the height of the brick proportion of the wall, you would need to know the total height of the wall first. Once you have the total height, you can calculate the height of the brick section by multiplying the total height by the fraction of the wall that is brick. For example, if 3/5 of the wall is made from brick, and the wall is 220 cm high, the calculation would be as follows:

Height of brick portion = Total height of the wall × Fraction of wall that is brick

Height of brick portion = 220 cm × (3/5) = 132 cm

Therefore, the height of the brick proportion of the wall would be 132 cm.

The three steps in Factoring Completely are:

Factor a GCF from the expression, if possible.
Factor a Trinomial, if possible.
Factor a Difference Between Two Squares as many times as possible.

Final answer:

Factoring completely involves three steps: identifying the GCF, applying the appropriate factoring method, and checking for additional factors. Factoring by grouping is used when there are four terms in an expression and common factors can be factored out separately. An example is given to illustrate the factoring by grouping process.

Explanation:Factoring Completely:Identify the greatest common factor (GCF) of the terms in the expression and factor it out.Apply the difference of squares, trinomial, or grouping method to factor the remaining expression.Check if there are any additional factors that can be factored further.Factoring By Grouping:

This technique is used when there are four terms in an expression and there is a common factor between the first two terms and the last two terms. The common factor is factored out separately from the two pairs, and then the resulting binomials are factored further.

Factoring by Grouping Example:

Consider the expression 2x + 3y + 4x + 6y. In this case, we can group the terms as (2x + 3y) + (4x + 6y). Common factors can be factored out separately, resulting in (2x + 3y)(1 + 2).

What is the length of one leg of the triangle

Answers

Answer:

Step-by-step explanation:

The length measure of the second leg of the right-angle triangle is 12 units.

What is the measure of the missing leg length of the triangle?

Given the parameter:

Hypotenuse = 15 units

Length of leg1 = 9 units

Length of leg2 = x

To determine the measure of the missing side length of the right triangle, we use the Pythagoras theorem.

It is expressed as:

( hypotenuse )² = ( leg 1 )² + ( leg 2 )²

Plug in the given values:

( 15 )² = ( 9 )² + ( leg 2 )²

Simplifying, we get:

225 = 81 + ( leg 2 )²

( leg 2 )² = 225 - 81

( leg 2 )² = 144

Take the square roots:

leg 2 = √144

leg 2 = 12 units

Therefore, the second leg measures 12 units.

By the Triangle Inequality Theorem, if two sides of a triangle have lengths of 6 and 13, what are the possible lengths of the third side?

Answers

The Triangle Inequality Theorem establishes that the length of the triangle is shorter than the sum of the two lenghts of the others two sides. Then, you have:

a=6 (the lenght of a side of the triangle).
b=13 (the lenght of a side of the triangle).
c=x (the length of the third side).

Therefore:

c<a+b
c<6+13
c<19

The lenght of the third side is:

(13-6)<c<19
7<c<9

In this exercise we have to use the knowledge of triangles to calculate the value of the third side, so we have:

We evaluate for y = 10, z = 5:
0.3 (10) + (10) / (5)
3 + 2
5
Answer:
0.3y + y / z
For
y = 10
z = 5
the result is 5.

When [tex]$ y = 10 $ and $ z = 5 $[/tex], [tex]$ 0.3y + \frac{y}{z} $ equals $ 5 $[/tex].

Step 1 :

To evaluate the expression [tex]$0.3y + \frac{y}{z}$ when $y = 10$ and $z = 5$[/tex], follow these steps:

1. Substitute the given values of [tex]$y$ and $z$[/tex] into the expression:

[tex]\[0.3 \times 10 + \frac{10}{5}\][/tex]

2. Calculate each term separately:

- [tex]$0.3 \times 10 = 3$[/tex]

- [tex]$\frac{10}{5} = 2$[/tex]

3. Add the results:

[tex]\[3 + 2 = 5\][/tex]

So, when [tex]$y = 10$ and $z = 5$[/tex], the expression [tex]$0.3y + \frac{y}{z}$ equals $5$.[/tex]

Step 2 :

1. Multiply 0.3 by 10:

[tex]\[0.3 \times 10 = 3\][/tex]

2. Divide 10 by 5:

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

3. Add the results:

[tex]\[3 + 2 = 5\][/tex]

Thus, when [tex]$y = 10$ and $z = 5$[/tex], the expression [tex]$0.3y + \frac{y}{z}$ equals $5$.[/tex]

Answers

First you need to use the standard form of a circle and then transform it into the general form of a circle.

Standard Form of a Circle.
[tex](x - h)^2 + (y - k)^2 = r^2[/tex]

To use the standard form of a circle, we need to know the center of the circle and the radius of the circle. Our center is at (-2, -3), which is (h, k). Our radius is half of the diameter, which the diameter is 8 so 8 / 2 = 4. So we have a radius of 4.
In our Standard Form of a Circle, the h = -2 and the k = -3 and the 4 = r
Now we can turn this into the general form of a circle.

Insert our point (-2, -3) and our radius of 4 into the standard form of a circle equation and transform it into the general form.

[tex](x - h)^2 + (y - k)^2 = r^2[/tex]
[tex](x - (-2))^2 + (y - (-3))^2 =4^2[/tex]
[tex](x + 2)^2 + (y + 3)^2 = 4^2[/tex]
[tex](x + 2)^2 + (y + 3)^2 = 16[/tex]
Expand (x + 2)^2
[tex]x^2 + 4x + 4 + (y + 3)^2 = 16[/tex]
Expand (y + 3)^2
[tex]x^2 + 4x + 4 + y^2 + 6y + 9 = 16[/tex]
Move the 16 over to the left side by adding a - 16
[tex]x^2 + 4x + 4 + y^2 + 6y + 9 - 16 = 16 - 16[/tex]
[tex]x^2 + 4x + 4 + y^2 + 6y + 9 - 16 = 0[/tex]
Now arrange and combine like terms
[tex]x^2 + 4x + 4 + y^2 + 6y + 9 - 16 = 0[/tex]
Gathering all constant values
[tex]x^2 + 4x + y^2 + 6y + 9 -16 + 4 = 0[/tex]
Gathering all x and y values
[tex]x^2 + 4x + y^2 + 6y + 9 - 16 + 4 = 0[/tex]
[tex]x^2 + y^2 + 4x + 6y + 9 - 16 + 4 = 0[/tex]
Combining all constant terms
[tex]x^2 + y^2 + 4x + 6y + 9 - 16 + 4 = 0[/tex]
[tex]x^2 + y^2 + 4x + 6y - 3 = 0[/tex]
