Answer:

Step-by-step explanation:

It is stated that a function rule takes an input, and converts it into an output, y, by decreasing twice the input by 4.

Let 'x' be the number

Decreasing twice the number 'x' by 4 = 2x-4

Now,

Given the input x = 5

As the output will decrease twice the input (x=5) by 4

Thus, the output = 2(5)-4 = 10-4 = 6

Therefore,

Answer:

1/4 × 3/1

QS/AC=6/60=1/10

QR/AB=QR/50=1/10

QR=5

SO THAT TRIANGLE ABC IS EQUAL TO TRIANGLE QRS(2SIDES PROPORTIONAL.INC. ANGLE)

Answer:

QR = 5

Step-by-step explanation:

It's given that ∆ABC ~ ∆QRS. As both of them are similar , the ratio of corresponding sides of both triangles will be proportional to each other.

[tex] \frac{AB}{QR} = \frac{BC}{RS} = \frac{AC}{QS} [/tex]

AB = 50 ; AC = 60 ; QS = 6

From the above proportion ,

[tex] \frac{AB}{QR}= \frac{AC}{QS}[/tex]

Putting all the values ,

[tex] \frac{50}{QR} = \frac{60}{6} [/tex]

[tex] = > \frac{50}{QR} = 10[/tex]

[tex] = > QR = \frac{50}{10} = 5[/tex]

Answer: D) Janelle can type 1/4 of a page in 2/3 of a minute

Step-by-step explanation:

Option A is wrong because based on the constraints, Janine would type less than 3/8 of a page in anything less than a minute. 8 > 3/8.

For that same reason, option B is wrong as well. 2 > 3/8.

1/2 > 3/8 so Option C is wrong for the same reason as the options above.

To test option D;

If Janine can type 3/8 of a page per minute, how much can she type in 2/3 minutes.

Assume the much she can type is x;

3/8 : 1

x    : 2/3

1x = 3/8 * 2/3

x = 1/4

Option D is therefore correct.

Answer:

The coordinates of the fourth vertex are (8,5)

Step-by-step explanation:

We need to take note that a rectangle is a shape that has 4 sides, with two of them of equal length.

It will also help if we can visualize the points on the graph.

We are given the location of three of the four vertices. These are (6,3), (6,5) ,and (8,3). Let the 4th Vertice be (x,y)

The length of the triangle can be obtained by subtracting the y-coordinates of the vertices.

(6,3) - (6,5)

This will be +3 and +5

5-3 =2

Therefore, the length of the triangle is 2 units on the left side.

Recall that the length of the left side has to be equal to the length of the right side.

Therefore

y-3 =2

y = 5

We will repeat the same process to get the x-coordinate from the breadth

Breadth = 8-6 =2

x-6 =2

x=8

Hence the x = 8

Therefore, the coordinates of the fourth vertex are (8,5)

Based on the given equation of b -4/6=b/2, the value of the variable b, can be found to be -2

The variable can be found by solving the equation through the operations of mathematics.

First, cross-multiply:

b -4/6 = b/2

b - 4 = 6b / 2

After cross-multiplying, collect like terms:

b - 4 = 3b

b - 3b = 4

-2b = 4

b = 4 / -2

b = -2

In conclusion, the variable is -2.

The equation that represents the cost of each bag of apples is 5x + 4.36 = 24.26 and the cost is $3.98.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

Isaac buys eggs and apples at the store. He pays a total of $24.26. He pays a total of $4.36 for the eggs. He buys 5 bags of apples that each cost the same amount.

Let x be the cost of each bag of apples. Then the equation is given as,

5x + 4.36 = 24.26

Simplify the equation, then we have

5x = 24.26 - 4.36

5x = 19.90

x = 19.90 / 5

x = $3.98

The equation that represents the cost of each bag of apples is 5x + 4.36 = 24.26 and the cost is $3.98.

The answer is the second choice.

There cannot be repetitive domains in one set. Therefore, all choices except the second choice have repetitive domains.

Thus, not making them a function but rather a relation instead for other choices. The only relation that is a function here is the second choice.

the second one because the x values should not have repeating numbers

Answer:

Step-by-step explanation:

We can immediately elimate two answers since x cannot be larger than the hypotenuse, which is 9. You can cosine = adjaent/hypotenuse, which gives the equation cos(54) = x/9, which simplifies to x = 9*cos(54). When you plug this into a calculator, you should get 5.29. Keep in mind that 54 is measured in degrees and not radians because.

Answer:

D.) x = 5.29

Step-by-step explanation:

first find the last angle measure 180-90-54=36

use law of sines to find x

sin90/9=sin36/x

(sin90)(x) = (sin36)(9)

(sin90)(x) = 5.29

x = 5.29

Answer:

40%

Step-by-step explanation:

To find the percentage difference between the families with 2 dogs and the families with no dogs, we need to find their difference first.

Difference = 45 - 27

                  = 18

Now that we know the difference, we just have to put the difference over the total as a fraction and multiply by 100%.

Percentage difference = [tex]\frac{18}{45}[/tex] × 100%

                                      = 40%

Hanna have to walk her bike for 1/12 mile to complete the loop .

In the question , it is given that

distance Hanna had to ride to complete the loop  = 11/12 mile

distance rode by Hanna before rest = 1/2 mile

distance rode by Hanna before flat tire = 1/3 mile

So the distance Hanna has to walk her bike to complete the loop = total distance of the loop - distance rode by Hanna before rest - distance rode by Hanna before flat tire .

On substituting the values from above we get ,

distance Hanna has to walk her bike to complete the loop = 11/12 - 1/2 - 1/3

taking the LCM of 12 , 2 and 3 as 12

we get ,

= 11/12 - 6/12 - 4/12

Simplifying further we get ,

= (11-6-4)/12

= (11-10)/12

= 1/12

Therefore , the distance Hanna have to walk her bike to complete the loop is 1/12 mile .

Answer and Step-by-step explanation: x represent the number of $5 bills and y, the number of $10 bill and, in total there are 32 bills, so

x + y = 32

In terms of value, there is a total of $220. The equation for it is

5x + 10y = 220

The 2 equations which best represent the scenario are

x + y = 32 (I)

5x + 10y = 220 (II)

To know how many bills there are, we have to solve the system. There are many way to solve it and one of them is

1) Multiply (I) by -5:

-5x - 5y = -160 (III)

2) Add equation (III) to equation (II):

-5x - 5y = -160

5x + 10y = 220

0x + 5y = 60 (IV)

3) Solve equation (IV)

5y = 60

y = 12

4) Replace value of y in equation (I) and find value of x:

x + 12 = 32

x = 20
