8. Sheila buys two concert tickets from her friend.
She pays $90 for the two tickets. She looks at the
tickets and sees that each ticket has a face value
of $52.50.

B.What was the percent markdown, rounded to the nearest whole percent

Answers

Cost of two tickets that Sheila paid to her friend = $ 90

Actual price of 1 ticket = $ 52.50

So, actual price of 2 tickets = 52 x 2 = 105

Hence, markdown or discount Sheila's friend gave her is =

105 - 90 = 15

The answer is $15.

a tree of 14 m height is broken so that its top touches ground and makes an a 60 degeree.find the length of broken part of tree​

Answers

Answer:

98 - 24√3 is your answer dear.

Step-by-step explanation:

Let the length of broken part of the tree = 14 - x

For finding x

sin60° = √3/2 = x /14-x

14√3 - √3x = 2x

14√3 = 2x + √3x

14√3 = (2 + √3)x

x = 14√3/(2 + √3)x

after rationalisation

x = 24√3 - 84

substract it 14 - (24√3 - 84)

YOU'LL GET 98 - 24√3 WHICH IS YOUR ANSWER.

Answers

Answer:

x=7,  angle a= 45 degrees, angle b= 65 degrees

Step-by-step explanation:

All the angles in a triangle must add up to 180. Subtract 70 from 180, add both angle a and angle b to get 16x-2=110, solve for x, x=7. Substitute x out for 7 in the equations then simplify to get angle a=45 and angle b=65

Answer:

x = 7

m∠B = 65

m∠A = 45

Step-by-step explanation:

So we know that the inside of a triangle equals 180º. So we have one angle already, 70º, so what we can do is subtract 70 from 180.

180 - 70 = 110

Now we can set both equations equal to 110.

2 + 9x + 7x - 4 = 110

Now simplify.

2 + 9x + 7x - 4 = 110

2 + 16x - 4 = 110

16x - 2 = 110

      +2       +2

------------------

16x = 112

÷16       ÷16

-----------------

x = 7

So now you can just plug 7 in for x to check your answers

2 + 9(7) = 65

7(7) - 4 = 45

65 + 45 + 70 = 180

3/5 divided by 2 1/2

Answers

Step-by-step explanation: To divide mixed numbers, first rewrite the mixed numbers as improper fractions.

So here, 3/5 is already a fraction and 2 and 1/2 can be written as 5/2.

Remember that dividing by a fractions means the same thing

as multiplying by the reciprocal of that fraction.

In other words, 3/5 ÷ 5/2 can be rewritten as 3/5 · 2/5.

Finally, multiplying across the numerators and the

denominators, we have 6/25.

The result of the division of 3/5 divided by 2 1/2 is: 6/25.

Here, we have,

Select the correct answer. A model rocket was launched from the top of a building. The rocket's approximate height can be modeled by the quadratic equation h = -4.9t2 + 53.9t + 127.4, where h is the rocket's height, in meters, after t seconds. When factored, this equation is h = -4.9(t - 13)(t + 2). What is a reasonable time for it to take the rocket to land on the ground? Answer A 11 seconds Answer B 13 seconds Answer C 2 seconds Answer D 15 seconds

Answers

Answer:

13 seconds.

Step-by-step explanation:

Given

[tex]h = -4.9(t - 13)(t + 2).[/tex]

Required

Determine a reasonable solution for t

To do this, we equate h to 0.

[tex]h = -4.9(t - 13)(t + 2).[/tex] becomes

[tex]0 = -4.9(t - 13)(t + 2).[/tex]

Divide through by -4.9

[tex]0 = (t - 13)(t + 2).[/tex]

Reorder the expression

[tex](t - 13)(t + 2) = 0.[/tex]

Split

[tex]t-13 = 0[/tex] or [tex]t + 2 = 0[/tex]

This gives:

[tex]t = 13[/tex] or [tex]t = -2[/tex]

But time can't be negative, So:

[tex]t = 13[/tex]

Answers

Answer:

Anniversary sale price= $570

Step-by-step explanation:

Giving the following information:

Purchase cost= $400

Mar-up percentage= 90%

First, we need to calculate the "normal" selling price:

Selling price= 400*1.9= $760

Now, we can determine the anniversary sale price:

Anniversary sale price= 760 - (760*0.25)= $570

Ann and Ruth bowled together and had a combined score of 410 points. Ann's score was 44 points less than Ruth's score. Write a system of equations that can be used to determine x, Ann's score and y, Ruth's score.

Answers

Answer:

x=y-44 and x+y=410

Step-by-step explanation:

So, you want to use the equations x=y-44 and  x+y=410 when x is Ann's score and y is Ruth's score. This is because x (Ann's score) is Ruth's score (y) but 44 less, so you subtract y-44 to get x. Then x+y would also have to equal 410 so that's the other equation. Graphing the 2 equations gets you to the point  (183,227) in which Ann's score is 183 points and Ruth's score is 227 points.
