The ratio of quarters to dimes is not still 5 : 3

Solution:

Given that ratio of quarters to dimes in a coin collection is 5:3 .

You add same number of new quarters as dimes to the collection .  

Need to check if ratio of quarters to dimes is still 5 : 3

As ratio of dimes and quarters is 5 : 3

lets assume initially number of quarters = 5x and number of dimes = 3x.

Now add same number of new quarters as dimes to the collection

Let add "x" number of quarters and "x" number of dimes

So After adding,

Number of quarters = initially number of quarters + added number of quarters = 5x + x = 6x

Number of dimes = initially number of dimes + added number of dimes

= 3x + x = 4x

New ratio of quarters to dimes is 6x : 4x = 3 : 2

So we have seen here ratio get change when same number of new quarters and dimes is added to the collection

Ratio get change from 5 : 3 when same number of new quarters and dimes is added to the collection and new ratio will depend on number of quarters and dimes added to collection.

Answer:

(a) The cost of 1  model house A  = $24

(b) YES, with $200 Victor can purchase 3 A model &  4 B model houses.

Step-by-step explanation:

Let us assume the cost of  model house B = $ m

So, the cost of model house A  =$ ( m - 6)

So, the price of 5 A model house = 5 x ( Rate of 1 model house A)

                                                         = 5(m-6)

And, the price of 3 B model house = 3 x ( Rate of 1 model house B)

                                                         = 3 x (m) = 3 m

So, the cost of 3 B house +  5 A house =  5(m-6)  +  3 m

⇒5(m-6)  +  3 m  = $210

or, 5 m - 30 + 3 m = 210

or, 8 m = 240

or, m = 30

So, the cost of 1 B house = m = $30

And  the cost of 1 house A = (m -6) = (30 - 6) = $24

Now, The  cost of 3 A model + 4 B model

=  3( 24)  + 4(30)   = 72 + 120 =  192

So, The  cost of 3 A model + 4 B model  = $192 and $192 < $200

Hence, YES, with $200 Victor can purchase 3 A model + 4 B model houses.

I'm assuming your teacher wants you to translate the given sentence into an algebraic expression.

y = some unknown number

4y = 4*y = four times a number y

4y+8 = four times a number, y, increased by 8

Answer:

x = 1

Step-by-step explanation:

Well the first step is to apply the distributive property:

4(3x - 1) is equal to (12x - 4). You DISTRIBUTE a '4' to what is inside the parentheses.

And btw, to make it easier, you can make 9 - x so that x is first. For example, (-x + 9). They're both the same thing, just written differently.

Your new equation is 12x - 4 = -x + 9. You want to now solve the equation.

Add the (-x) to both sides. It cancels out on the right side and you add it to 12x on the left side.

[If there's no number in front of a variable, you can always just put 1 in order to make it easier]

12x + 1x = 13x. Your new equation is 13x - 4 = 9. This should look very familiar. You simply add 4 to both sides. 9 + 4 = 13

Finally, 13x = 13. Divide 13 ÷ 13 to get 1.

x = 1

Answer:

the answer is type 2

Step-by-step explanation:

ok so you first have to find the ratio of all of them and for type 1 it is 40 to 1 for type 2 it is 50 to 1 type 3 is 25 to 1 and type 4 is 30 to 1 so there for type two has the biggest ratio of fragrance to wax

The required table that has a higher ratio of fragrance to wax is type 2.

As given in the question, a company makes four different types of candles. The ratio of fragrance to wax for each type of candle is shown in the tables.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,
For Type 1
The ratio of Fragrance to wax.
= 20 / 0.5 = 40 / 1

For Type 2
The ratio of Fragrance to wax.
= 150 / 3 = 50 / 1

For Type 3
The ratio of Fragrance to wax.
= 250 / 10 = 25

For Type 4
The ratio of Fragrance to wax.
= 30 / 1

Now,
50 > 40 > 30 > 25
Type 2 > type 1 > type 3 > type 4

Thus, the required table that has a higher ratio of fragrance to wax is type 2.

Answer:

The coordinates of the original triangle are (2,4). (4,1) and (1,1)

Step-by-step explanation:

About the origin, I have to rotate a triangle 90° counterclockwise. Then I translate its image 1 unit left and 2 units down.

The vertices of the final image are (-5,0), (-2,2), and (-2,-1).

We need to get the vertices of the original triangle.

So, start from a triangle with vertices (-5,0), (-2,2), and (-2,-1) and do the reverse to get the original triangle.

So, we will translate the image triangle by 1 unit right and 2 units up and we will get the triangle with vertices (-5 + 1, 0 + 2), (- 2 + 1, 2 + 2) and (- 2 +1, - 1 + 2)  ≡ (-4,2), (-1, 4) and (-1,1).

Now, we have to rotate this intermediate triangle by 90° clockwise.

Therefore, the coordinates of the original triangle are (2,4). (4,1) and (1,1) (Answer)

{Since, for 90° rotation the coordinates of all the vertices will interchange their location (i.e. x-value to y-value and y-value to x-value) and a negative sign will be added to the y-coordinate of the interchanged coordinates}  

One number is 7 less than a second number. Twice the second number is 1 less than 5 times the first. Then the two numbers are 5 and 7

Solution:

Given that one number is 7 less than a second number.

Twice the second number is 1 less than 5 times the first.

Need to determine two numbers.

Let assume first number be represented by variable x and second number be represented by variable y.

As first number is 7 less than a second number, adding 7 to first number will give us second number

=> x + 7 = y   ------ (1)

[tex]\begin{array}{l}{\text { Twice of second number }=2 \times \text { second number }=2 \times y=2 y} \\\\ {\text { 5 times the first number }=5 \times \text { first number }=5 \times x=5 x}\end{array}[/tex]

As given that Twice the second number is 1 less than 5 times the first , if we 1 to twice of second number we will get 5 times first number ,

=> 2y + 1 = 5x     ------ (2)

On substituting value of y as x + 7 from equation 1 into equation 2 , we get

2(x + 7) + 1 = 5x      

=> 2x + 14 + 1 = 5x

=> 2x – 5x = -15

=> -3x = -15

x = 5

Substituting x = 5 in equation (1) to get value of y  

=> y = 5 + 7 = 12

Hence first number is 5 and second number is 12

Answer:

No

Step-by-step explanation:

3(x+11/2)-3 = 3x + 33/2 -3 = 3x + (33-6)2 = 3x + 27/2

The expression 3(x+1 1/2)-3 is equivalent to 3x+1 1/2 once the distributive property is applied and the constants are combined.

The expression 3(x+1 1/2)-3 is not equivalent to 3x+1 1/2. To determine the equivalency, we need to apply the distributive property to the expression on the left-hand side. The distributive property states that we can multiply the outside term by each term inside the parentheses. Thus, the expression 3(x+1 1/2) becomes 3x + 4 1/2. When we subsequently subtract 3 from 4 1/2, we get 1 1/2, which results in the final expression of 3x + 1 1/2. This confirms the expressions are equivalent.

Answer:

The width of the base is 2.828 feet

Explanation:

Given the area of the table top is 4 square feet

The triangular table top is twice as high as it is wide at the base

Therefore, we can say that height = base

Area of a right angled triangle is calculated by, Area = ½ * base * height  

In this case, height = base

Therefore, area =[tex]\frac{1}{2}\times (base)^2[/tex]

Substituting the values,

4 = [tex]\frac{1}{2}\times (base)^2[/tex]

[tex](base)^2[/tex]  = 8

Base = 2√2 = 2 * 1.414 = 2.828 feet

Therefore, the width of the base is 2.828 feet

Answer:

The quantity of type A coffee is 73 pounds

The quantity of type B coffee is 94 pounds .

Step-by-step explanation:

Given as :

The price of Type A coffee costs = $ 5.70 per pound

The price of Type B coffee costs = $ 4.30 per pound

The total quantity of coffee does Reuben purchases = 167 pounds

The total cost of the coffee for 167 pounds = $ 820.30

Let The quantity for type A coffee = a pounds

And The quantity of type B coffee = b pounds

Now, According to question

a + b = 167 pounds      And

$ 5.70 × a + $ 4.30 × b = $ 820.30

Now solving equations

5.70 × ( a + b ) = 5.70 × 167

or, 5.70 a + 5.70 b = 951.9

Now ,

( 5.70 a + 5.70 b ) - (   5.70  a +  4.30  b ) = 951.9 - 820.30

or, ( 5.70 a - 5.70 a ) + ( 5.70 b - 4.30 b ) = 131.6

Or, 0 + 1.4 b = 131.6

∴ b = [tex]\frac{131.6}{1.4}[/tex]

I.e b = 94 pounds

Put the value of b to get a value

So, a = 167 pounds - b

Or, a = 167 - 94

∴   a = 73 pounds

Hence The quantity of type A coffee is 73 pounds

And The quantity of type B coffee is 94 pounds   .  Answer

The percent equation showing the fiction books is y = 0.65x showing that among the 4,000 books in the library, 2,600 are fiction.

An equation is a mathematical representation of the equality of two expressions.

The number of books in the town's library = 4,000

The number of fiction books = 2,600

The number of nonfiction books = 1,400 (4,000 - 2,600)

The percentage of fiction books to the total number of books = 65% (2,600/4,000 x 100)

Let the total number of books in the library = x

Let the number of fiction books = y

Equation:

y = 0.65x

y = 2,600 (0.65 x 4,000)

Answer:

d = 49

Step-by-step explanation:

Given that the expression is a perfect square of the form

(ay - b)² = a²y² - 2aby + b²

Then comparing like terms

a²y² = 25y², that is

a² = 25 ⇒ a = 5

and -2aby = - 70y, thus

2ab = 70, that is

2(5)b = 70

10b = 70 ⇒ b = 7

b² = 7² = 49

Hence

25y² - 70y + d = (5y - 7)² = 25y² - 70y + 49

Thus d = 49
