Answer:

D. 60, 45,75

Step-by-step explanation:

For options C and D

For a triangle the sum of the angles must always be equal to 180 degrees

So 180 ≠45+45+80

and

60 +45+ 75= 180

For option A and B

The length of the longer side is equal to the square root of the sum of squares of the other two sides in a triangle.

According to Pythagorus theorem

hypotenuse²= base² + perpendicular²

c²= a²+ b²

90²= 50² + 35²

8100= 2500+1225

8100≠3725

95²= 60²+ 25²

9025= 3600+ 625

9025≠4225

Therefore only D is the correct option

Answer:

75 sq units

Step-by-step explanation:

A = lw

l = OP = distance between (9, 6) and (0, -6)

          = [tex]\sqrt{(9 - 0)^{2} + (6 + 6)^{2} }[/tex]

         = [tex]\sqrt{81 + 144)} = \sqrt{225} = 15[/tex]

w = MP =  distance between (-4, -3) and (0, -6)

            = [tex]\sqrt{(-4 - 0)^{2} + (-3 + 6)^{2} }[/tex]

            = [tex]\sqrt{16 + 9} = \sqrt{25} = 5[/tex]

A = 15(5) = 75 sq units

Answer:

[tex]d = \sqrt{122} \: in[/tex]

Step-by-step explanation:

D^2 = x^2 + y^2 + z^2

= (9 in)^2 + (5 in)^2 + (4 in)^2

= 122 in^2

or

[tex]d = \sqrt{122} [/tex]

Answer: $ 27.50

Step-by-step explanation:

We know that $24.75 is (100%-10%) = 90% of the original price.

24.75/90 = 0.275 (to find one percent)

0.275 x 100 = 27.5 (100%, the original price)

Answer:

45

Step-by-step explanation:

Since the lines of hypotenuse are parallel,the triangles are similar

20/8 = x/18

cross multiplication

8x = 20x18

8x=360

x=45      

Answer:

$637.5

Step-by-step explanation:

Given data

Cost of  merchandise= $750

Discount= 15%

Let us find the amount of the discount

=15/100*750

=0.15*750

=$112.5

Hence the amount paid will be

=750-112.5

=$637.5

Answer:

[tex]P(Not\ Star) =\frac{2}{3}[/tex]

Step-by-step explanation:

Given

See attachment

Required

Theoretical probability that a roll will not land on a star

From the attachment, we have:

[tex]n = 12[/tex] --- Total space

[tex]Star = 4[/tex]

So, the theoretical probability that a roll will land on a star is:

[tex]P(Star) = \frac{n(Star)}{n}[/tex]

[tex]P(Star) = \frac{4}{12}[/tex]

[tex]P(Star) = \frac{1}{3}[/tex]

Using the complement rule, the probability that it will not land on a star is:

[tex]P(Not\ Star) = 1 - P(Star)[/tex]

[tex]P(Not\ Star) = 1 - \frac{1}{3}[/tex]

Take LCM

[tex]P(Not\ Star) =\frac{3-1}{3}[/tex]

[tex]P(Not\ Star) =\frac{2}{3}[/tex]

Step-by-step explanation:

Answer:

y=63, x=20, x=47, b=70, c=89, x=133

Step-by-step explanation:

1) y=63- alternate angles are the same

2) 4x+5x=180

9x=180

x=20

3) x=47

4) b=70- angles on a line equal to 180

c=89- angles in a triangle add up to 180

5) x=133- angles that are alternate are the same

Answer:

No

Step-by-step explanation:

First subtract 16 from both sides

13 is not a solution to the original inequality.

Answer:

6 and 12

Explanation:

(b.) is under set A but not set B, meaning that all the elements there are multiples of 3 that are not odd numbers.

all the multiples of 3 that are less than 16: 3 6 9 12 15

all the multiples of 3 that are even numbers: 6 12

thus, the elements that go in (b.) are 6 and 12.

Answer:

The statement that gives the best conclusion that should be made based on the results and provides the best explanation for the conclusion is option D;

D. It is reasonable to conclude that the difference in sales was caused by the different cover designs because the cover designs were randomly assigned to stores

Step-by-step explanation:

The data given in the question are presented as follows;

The particulars the CD manufacturer wants to determine = The CD cover design that will generate more sales

The mode of selection of the stores for the test = Random selection

The number of stores in each group of stores, n = 35 stores

The number of sets of stores tested = 2 sets of stores

Let [tex]\overline x_1[/tex] represent the mean number CDs sold at one set of stores and [tex]\overline x_2[/tex] represent the mean number CDs sold at the other set of stores

The null hypothesis, H₀; [tex]\overline x_1[/tex] = [tex]\overline x_2[/tex]

The alternative hypothesis, H₀; [tex]\overline x_1[/tex] ≠ [tex]\overline x_2[/tex]

Given that the statistical analysis shows that the difference in mean between the two sets of randomly selected stores is significant, we therefore should reject the null hypothesis and accept the alternative hypothesis that there is a significant difference in CD sale attributable to the difference in cover design as the CDs having on of two cover design where assigned randomly to the stores.

Answer:

81 m

Step-by-step explanation:

From the question given above, the following data were obtained:

Area (A) = 7371 m²

Length (L) = 91 m

Width (W) =?

Area of a rectangle is given by the following equation:

Area = Length × Width

A = L × W

With the above formula, we can obtain the width of the rectangular field as follow:

Area (A) = 7371 m²

Length (L) = 91 m

Width (W) =?

A = L × W

7371 = 91 × W

Divide both side by 91

W = 7371 / 91

W = 81 m

Thus, width of the rectangular field is 81 m

Answer:

The equation could be used to determine the number of emails, y, that will be sent for a given round, x, is:

Step-by-step explanation:

To obtain the equation you must know how many emails will be sent in each case, taking into account that Jesse requested that each person copy and send the same email to 4 additional people, then:

How you can see, each round is the same that to multiply the last sent emails by four, so, with the equation selected in the answer we can obtain these results:

In the first round:

In the second round:

In the third round:

And, in the fourth round:
