4. A local bakery sold 60 loaves of bread in one day. If 65%
of these were sold in the afternoon, how many loaves were
sold in the afternoon?

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 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:

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:

(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.

Answer:

x = -8 , y = -2

Step-by-step explanation:

Solve the following system:

{3 x - 4 y = -16 | (equation 1)

2 x - 4 y = -8 | (equation 2)

Subtract 2/3 × (equation 1) from equation 2:

{3 x - 4 y = -16 | (equation 1)

0 x - (4 y)/3 = 8/3 | (equation 2)

Multiply equation 2 by 3/4:

{3 x - 4 y = -16 | (equation 1)

0 x - y = 2 | (equation 2)

Multiply equation 2 by -1:

{3 x - 4 y = -16 | (equation 1)

0 x+y = -2 | (equation 2)

Add 4 × (equation 2) to equation 1:

{3 x+0 y = -24 | (equation 1)

0 x+y = -2 | (equation 2)

Divide equation 1 by 3:

{x+0 y = -8 | (equation 1)

0 x+y = -2 | (equation 2)

Collect results:

Answer: {x = -8 , y = -2

the solution to the system of equations is [tex]\( x = -8 \) and \( y = -2 \).[/tex]

To solve this system of equations, we can use the method of substitution or elimination. Let's use the elimination method here.

Given equations:

1.[tex]\(3x - 4y = -16\)[/tex]

2.[tex]\(2x - 4y = -8\)[/tex]

We can see that both equations have the same term ( -4y), so we can eliminate ( y) by subtracting equation 2 from equation 1:

[tex]\[(3x - 4y) - (2x - 4y) = (-16) - (-8)\][/tex]

[tex]\[3x - 4y - 2x + 4y = -16 + 8\][/tex]

[tex]\[(3x - 2x) - 4y + 4y = -16 + 8\][/tex]

[tex]\[x = -8\][/tex]

Now that we have found ( x = -8 ), we can substitute this value into either of the original equations to find ( y ).

Let's substitute ( x = -8 ) into equation 1:

[tex]\[3(-8) - 4y = -16\][/tex]

[tex]\[-24 - 4y = -16\][/tex]

[tex]\[-4y = -16 + 24\][/tex]

[tex]\[-4y = 8\][/tex]

[tex]\[y = \frac{8}{-4}\][/tex]

[tex]\[y = -2\][/tex]

So, the solution to the system of equations is [tex]\( x = -8 \) and \( y = -2 \).[/tex]

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

or  T ∝ F when t is constant

3.The tuition fee (M) taken by my sister's school for her studies is proportional to the no. of months(H) she is in that school,

or  M ∝ H

Final answer:

Examples of proportional relationships include electricity bills proportionate to usage, water in a tank related to tap flow time, and pay from a job based on the number of performed tasks.

Explanation:

Proportional relationships involve constants of proportionality which indicate a direct or inverse relationship between two quantities. For example, in a household setting, the electricity bill is directly proportional to the amount of electrical usage; the higher the usage, the higher the bill. Similarly, the amount of water in a tank can be seen as directly proportional to the time the tap runs if the flow rate is constant. Additionally, the pay for a college work-study job, such as making calls for donations, can be directly proportional to the number of calls made; if you're paid $2.50 per call, doubling the number of calls doubles your pay.

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

1/3 or 0.33 feet

Step-by-step explanation:

This question can be easily answered by using simple proportions.

If 75 feet are represented by 45 inches on a scale, then the scaling factor from feet to inches is 45/75, or from inches to feet is 75/45

If we have 1/5 inch and want feet, just multiply by 75/45 to get

1/5*75/45=1/3=0.33 feet

Answer:

1/3 feet

Step-by-step explanation:

We are given that

On a scale drawing

45 inches represented =75 feet

We have to find a scale of 1/5 inch how many feet represents.

To find the value in feet represented by  a scale of 1/5 inch we will use unitary method.

Using unitary method

45 inches represents =75 feet

1 inch represents =[tex]\frac{75}{45}[/tex] feet

1/5 inch represents =[tex]\frac{75}{45}\times \frac{1}{5}[/tex] feet

1/5 inch represents=[tex]\frac{1}{3}[/tex] feet

Hence, a scale of 1/5 inch represents 1/3 feet

Answer: y= 2/3

Answer:

b

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange both equations into this form

x - 6y = - 30 (subtract x from both sides )

- 6y = - x - 30 ( divide all terms by - 6 )

y = [tex]\frac{1}{6}[/tex] x + 5 ← in slope- intercept form

with slope m = [tex]\frac{1}{6}[/tex]

y = - 6x + 5 ← in slope- intercept form

with slope m = - 6

Parallel lines have equal slopes.

Clearly the lines are not parallel.

The product of the slope of perpendicular lines equals - 1, thus

[tex]\frac{1}{6}[/tex] × - 6 = - 1

Hence the lines are perpendicular → b

An isosceles triangle has an angle that measures 40 degrees. 70 and 100 are other angles could be in that isosceles triangle

Solution:

Given that isosceles triangle has an angle that measures 40 degrees.

If a triangle is isosceles then it has 2 identical angles and the third different one.

Let the two identical angles be "a"

We know that sum of angles in a triangle is 180 degree

a + a+ 40 = 180

2a + 40 = 180

2a = 180-40

a = 70

Thus the two identical angles are 70 degree and 70 degree

Now let the identical two angles be "40" and the third angle be "a"

Now sum of angles = 180 degree

40 + 40 + a = 180

80 + a = 180

a = 100

Thus the third angle in this case is 100

70 and 100 are other angles could be in that isosceles triangle

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:

There may be 3 tables or 1 table.

Step-by-step explanation:

If we factorize 12 into its prime factors then we get 12 = 2 × 2 × 3

If there are an odd number of tables and each table has an equal number of chairs and there are a total of 12 chairs, then the possibilities of the number of tables are 1 and 3.

{Since 1 and 3 both are odd numbers}

Now, for 3 tables there will be 4 chairs each to make the total chairs (3 × 4) = 12 and for 1 table there will be 12 chairs in the table to make the total number of chairs (1 × 12) = 12. (Answer)

To solve using prime factorization, the factors of 12 are 2, 2, and 3. We need an odd number of tables, so only the factor 3 is used. There are 3 tables with 4 chairs each.

The question involves a scenario where there are 12 chairs in a meeting hall and an odd number of tables. Each table has the same number of chairs. The question prompts us to use prime factorization to determine how many tables there could be. Since there is a fixed total of 12 chairs, we need to find the factors of 12 that are odd numbers because the number of tables has to be odd.

Using prime factorization, 12 can be broken down into its prime factors: 2 x 2 x 3. To have an odd number of tables, we cannot include the factor of 2 because it would result in an even number of tables. Hence, we only consider the factor of 3. In this scenario, this would mean there are 3 tables with 4 chairs each because 3 (an odd number) times 4 equals 12 (total number of chairs).

Another way to use prime factorization to solve this is to look for combinations of the factors that multiply to 12 but in groups that have an odd factor. The only possible combination is again 3 tables with 4 chairs each, as any other multiplication involving the factor 2 would result in an even number of tables.
