Answer:

No, she is not correct. Because this is a proportional relationship.

Step-by-step explanation:

Proportional relationships are relationships having equal ratios.

here, Mandy's conclusion is incorrect because the relationship is proportional, and it has a uniform ratio of 5.

column 1               column 2           column 2/column1

   'x'                            'y'          

    1                             5                               5

    2                            10                              5

    5                            25                             5

    10                           50                             5

As we clearly see that ratio of column 2 and column 1 is same for every row, therefore we can conclude that the given relation in the relation is proportional.

Thus,  the given relation is proportional.

Answer:

30

Step-by-step explanation:

Area of a triangle = (base length × height)/2

Given base length = 5 and given height = 12

So area = (5×12)/2

==> multiply 12 and 5

Area = (60)/2

==> divide 60 by 2

Area = 30

Slope is 3/4

Step-by-step explanation:

Gradient means slope. So, to find the slope without using the formula, look at two points then count up until you're in line with the other point, then count right until you reach the other point. Remember it must be written as rise/run.

I hope this explanation makes sense!

The points I will use is (0,-2) and (4,1).

Step-by-step explanation:

The option that needs to be corrected in this construction of a line parallel to line AB passing through C is C: the second arc should be centered at C.

The second arc should be centered at C because as it crosses passing through Line C, it is seen that it was not touching or intersecting AB and so one can say that it is parallel to it.

Looking at the other lines, we will see that they are all touching AB and are not running parallel to it.

Hence, The option that needs to be corrected in this construction of a line parallel to line AB passing through C is C: the second arc should be centered at C.

Answer:

slope = 5 , y- intercept = - 10

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 )

y = 5x - 10 ← is in slope- intercept form

with slope m = 5 and y- intercept c = - 10

The slope and y intercept of the function y = 5x - 10 is 5 and -10 respectively.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Equation of a line in slope intercept form is,

y = mx + b,

where m is the slope of the line and b is the y intercept,

y intercept is the y coordinate of the point where it touches the Y axis.

Given equation is y = 5x - 10.

Comparing with slope intercept form,

m = 5 and b = -10

Hence the slope of the line is 5 and y intercept is -10.

Cooper left his dinner server a 19% tip.

To find the percent tip, we need to first subtract the cost of the meal from the total amount paid, which will give us the tip amount:

Tip amount = Total amount paid - Cost of the meal

Tip amount = $33.32 - $28

Tip amount = $5.32

Now we can calculate the percentage of the tip by dividing the tip amount by the cost of the meal and multiplying by 100:

Percent tip = (Tip amount / Cost of the meal) x 100

Percent tip = ($5.32 / $28) x 100

Percent tip = 0.19 x 100

Percent tip = 19%

Therefore, Cooper gave a 19% tip on his dinner.

Step-by-step explanation:

Segment Addition Postulate

If a third point B lies on a line segment with endpoints A and C, then AB + BC = AC

Given:

Q is the point on the line segment OP, so:

⇒ OQ + QP = OP

Substitute the given values of OP and QP to find OQ:

⇒ OQ + 6 = 17

⇒ OQ + 6 - 6 = 17 - 6

⇒ OQ = 11

Answer:

XY = 6

Step-by-step explanation:

using the sine ratio in the right triangle and the exact value

sin30° = [tex]\frac{1}{2}[/tex] , then

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{XY}{XZ}[/tex] = [tex]\frac{XY}{12}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2 XY = 12 ( divide both sides by 2 )

XY = 6

The length of the side XY in ΔXYZ is 6 units.

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecen/hypotenuse and

tan = opposite/adjacent.

In reference to the angle of 30° opposite side is XY and the hypotenuse is 12 units.

We know, sin = opposite/hypotenuse.

Therefore, sin30° = XY/12.

1/2 = XY/12.

XY = 12/2.

XY = 6 units.

Answer:

A

Step-by-step explanation:

isolate r by dividing by πh. take the square root on both sides to get rid of the r^2 to make it just r

Answer:

r =sqrt(V/ ( pi h) )

Step-by-step explanation:

V = pi r^2 h

We want to solve for r

Divide each side by pi h

V/ ( pi h) = pi r^2 h/ ( pi h)

V/ ( pi h) = r^2

Now take the square root of each side

sqrt(V/ ( pi h) )= sqrt( r^2)

sqrt(V/ ( pi h) )=r

The perimeter is 48

Step-by-step explanation:

If the width is W

AT first , Length is 10 +w

According to the question,

[tex](w+8) (10+w+4) = 135\\(w+8) (w+14) = 135\\\\w^{2} + 14w + 8w + 112- 135 = 0\\\\ w^{2} + 22w - 23 = 0\\(w+23) (w-1) = 0\\\\w+ 23 = 0 w-1=0\\\\w= -13 or w = 1[/tex]

Expended width will be  w +8 = 1+8 = 9

Length is 10+w+4 = 15

So the perimeter is

= i2 x (9+15)

= 2x 24

= 48

The Solution to the problem of the rectangle is given below

For Part A:

For Part B

Meaning of Perimeter

The perimeter of any shape can be defined as the total sum of the sides of the shape.

For Part A

equation model= (14 + w) * (w +8) = 135

14w + 112 + 8w + [tex]w^{2}[/tex] = 135

[tex]w^{2}[/tex] + 22w - 23 = 0

solving the quadratic equation

w = -23 or 1

Because we are dealing with a physical quantity we will make use of the value 1

lenght of original rectangle = 10 + 1 = 11

Part B

Perimeter= 2(length) * 2 (breadth) = 2(11 + 4) * 2 (1 + 8)

Perimeter = 48

In conclusion, The Solution to the problem of the rectangle is given above.
