Sam bought a shirt, and the total came to $28.25. If Sam gave the clerk two $20 bills, how much change should Sam receive? Explain how you got your answer.

a. 12 deg, b. 168 deg

We can create a systems of equations using this information, since supplement angles add up to 180 deg and complementary angles add up to 90 deg, when angle = x deg and supplement = y deg,

x + y = 180

y = 2(90 - x ) + 12

Solving:

x + 2(90 - x) + 12 = 180

-x + 180 + 12 = 180

x = 12

12 + y = 180

y = 168

Answer:

The 65% markdown on $158.25 reduces the price by = $102.86

And the new amount price after 65% markdown = $158.25 - $102.86

                                                                                 = $55.39

Step-by-step explanation:

Given the amount

If the Markdown on $158.25 is 65%

i.e.

65% of $158.25 = 65/100 × 158.25

                           = 0.65 × 158.25

                           = $102.86

So, the 65% markdown on $158.25 reduces the price by = $102.86

And the new amount price after 65% markdown = $158.25 - $102.86

                                                                                 = $55.39

The length of parking lot in drawing will be 285 centimeters.

We are given the ratio of measurement in drawing to the measurement in real. In the ratio, 5 centimeters represents measurement in drawing and 2 meters represent drawing in real. Further, let the length of parking lot in real life be x centimeters.

Representing the mentioned information in ratio and proportion form - 5÷2=x÷114

Now performing cross multiplication of mentioned ratio and proportion to find the value of x.

2 × x = 5 × 114

Performing multiplication on Right Hand Side of the equation

2  × x = 570

Shifting 2 to denominator on Right Hand Side of the equation

x = 570÷2

Performing division on Right Hand Side of the equation

x = 285 centimeters.

Hence, the length of parking lot in drawing will be 285 centimeters.

Answer:

we conclude that the function shown in the graph has a smaller rate of change and a lower starting point.

Therefore, option (A) is true.

Step-by-step explanation:

FUNCTION

Given the function

y = 6x - 1

Comparing with the slope-intercept form of the graph

y = mx+b

where m is the slope and b is the y-intercept

Thus,

The slope of the function  = rate of change = 6

The starting point of the function can be obtained by setting x = 0 and solve for y

i.e

at x = 0, y = 6x-1 = 6(1)-1 = 5

Thus,

The starting point of the function is (0, 5)

LINE GRAPH

Now, consider the line graph

Taking two points to find the slope

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0,\:-6\right),\:\left(x_2,\:y_2\right)=\left(2,\:4\right)[/tex]

[tex]m=\frac{4-\left(-6\right)}{2-0}[/tex]

[tex]m=5[/tex]

Thus,

The slope of the line graph  =  rate of change = 5

From the graph, it is clear that at x=0, the value of y=6

Thus,

The starting point of the graph is (0, -6)

Thus,

FOR FUNCTION

The slope of the function  = rate of change = 6

The starting point of the function is (0, 5)

FOR LINE GRAPH

The slope of the line graph  = rate of change = 5

The starting point of the graph is (0, -6)

Conclusion

Hence, we conclude that the function shown in the graph has a smaller rate of change and a lower starting point.

Therefore, option (A) is true.

c. y = -x+5 represents a line that is parallel to line with points G(-3, 8) and H(0, 5)

First we will find slope of the points G(-3, 8) and H(0, 5) with the point-slope formula that is

y₂ - y₁ = m(x₂ - x₁) where m is the slope

So, substituting the value we get

⇒ 5 - 8 = m(0 - (-3))

⇒ -3 = m(3)

⇒ m = -3/3

⇒ m = -1

Thus, the slope of the line is -1. A parallel line will have the same slope as well, Therefor, we use the slope intercept form that is

(y = mx + b) where b is the y-intercept and m = -1

⇒ y = -1x + b

Out of all the options, only option c  y= -x+5 has a slope = -1, therefore

y= -x+5 represents a line that is parallel to line with points G(-3, 8) and H(0, 5)

The surface area is [tex]4\sqrt{2} \pi[/tex] units.

This problem is related to the triangle and solid figures.

If we rotate a triangle alongside one of its legs then it's going to shape a cone and the radius of the cone might be the duration of the bottom of the triangle and the hypotenuse of the triangle may be the slant peak of the cone.

The period of the the triangle legs is given to be 2 units.

Length of the hypotenuse=[tex]\sqrt{2^{2} +2^{2} }[/tex]

                                        = [tex]2\sqrt{2}[/tex] units.

Now the area of the cone is given by [tex]\pi rl[/tex] where r is the radius of the cone and l is the slant height of the cone.

Surface area of cone = [tex]\pi *2*2\sqrt{2}[/tex]

Answer:

94 degrees

Step-by-step explanation:

triangle is 180

so 180-74-20=86

The exterior angle is 74+20=94

94 is exterior angle

Answer:

x = 94°

Step-by-step explanation:

Any triangle has three angles whose measures add up to a total of 180°.

This triangle has two known angle measures. First, find the missing interior angle measure.

180 - (74 + 20)

180 - 94

86

The missing interior angle's measure is 86°. An exterior angle is supplementary to its adjacent interior angle, which means that the measure of the interior angle plus the exterior angle measure is 180.

180 - 86

94

Another way to find out a missing exterior angle measure is to simply add the measures of the two nonadjacent interior angles.

74 + 20

In mathematics, permutation relates to the act of arranging all of the contributors of a hard and fast into a few sequence or order. In other words, if the set is already ordered, then the rearranging of its elements is called the process of permuting. diversifications occur, in extra or less prominent methods, in almost every place of arithmetic. They regularly stand up whilst one of a kind orderings on positive finite sets are considered.

what's a combination?

The mixture is a manner of selecting objects from a collection, such that (not like permutations) the order of selection does now not matter. In smaller instances, it is feasible to be counted the wide variety of combinations. combination refers back to the mixture of n things taken ok at a time with out repetition. to consult combos in which repetition is authorized, the terms k-choice or k-mixture with repetition are regularly used.
