To pass her test, Tori needs to answer at least 65% of the questions correct. If there were 60
questions and she got 42 correct, did she pass? All work MUST be shown to justify your
answer.

Answers

Answer 1
1) change 65% to a decimal = .65

2) .65 • 60 = 37.2 questions need to be right

3) since she got 42 correct, that is greater than 37.2, so she passed.

OR

1) 42/60 = 0.7

2) 0.7 to a percent = 70%

3) since she got a 70% on the test, she passed.
Answer 2

Step-by-step explanation:

To obtain score of 80% on entire exam means the student have to answer

(80/100)×80 = 64 correct answers

Student have already answered 75% of the first 60 questions correctly meaning

(75/100)×60=45 correct answers from first 60 questions

Remaining correct answers s/he have to answer

64-45=19

So from remaining 20 questions s/he have to answer 19 correct questions that is

20 × (x/100) = 19

x = 19 ×(100/20)

x = 95%

USE THE SQUARE ROOT PROPERTY!!!!!

the sides of a square are reduced by 2 inches. the new area is 20 square inches. Set up and solve an equation to find the original length of the square

Answers

Answer:

Step-by-step explanation:

x = original length of one side

(x-2)² = 20 inches²

x-2 = ±√20 = ±2√5

x = 2±2√5

2-2√5 is an extraneous solution,

so x = 2±2√5 ≈ 6.47 inches

Points (4, 5) and (10, 5) are vertices of a rectangle.

The length of the rectangle is twice the width.

The other vertices are located at (4, ___ ) and (10, ___ ). What could these ordered pairs be?

pls help im begging yu

Answers

Answer:

the remaining two vertices must be (4, -7) and (10, -7).

Step-by-step explanation:

The vertices (4, 5) and (10, 5) lie on the same horizontal line, y = 5.  The length of the rectangle is the difference between the two x-coordinates:  10 - 4, or 6.

Let's denote 6 as the width.  Then the length is twice that, or 12.

Then the remaining two vertices must be (4, -7) and (10, -7).

Check:  is the width 6?  Does 10 - 4 equal 6?  Yes

Is the length twice the width, or 12?  Does 5 - (-7) = 12?  YES

The other vertices are located at (4, -7 ) and (10, -7)

Area of a rectangle

Given two points on a rectangle as (4, 5) and (10, 5)

Since both coordinates lies on the same y axis, then the width of the triangle is expressed as;

width = 2(10-4)

width = 12 units

The y coordinate of the other vertices will be;

y = 5 - 12

y = -7

Hence the other vertices are located at (4, -7 ) and (10, -7)

Answer:

B

Step-by-step explanation:

-the base angles are 34, so the total value of both base angles is 68

-an isosceles triangle is equal to 180

-subtract 68 from 180 for the answer, so the equation is 68+x=180

Miguel bought a table on sale for $266. This price was 65% less than the original price.
What was the original price?

Answers


p - 0.27p = $ 219

0.73p = $ 219

p = $ 219 / 0.73

p = $ 300. i don't know if this is fully right tho

Answer: 409.23

Step-by-step explanation:  Step 1: If 65% of a number is 266, then what is 100% of that number? Setup the equation.

266

65% = Y

100%

Step 2: Solve for Y

Using cross multiplication of two fractions, we get

65Y = 266 x 100

65Y = 26600

Y = 26600

100 = 409.23

You are the manager of a firm that manufactures front and rear windshields for the automobile industry. Due to economies of scale in the industry, entry by new firms is not profitable. Toyota has asked your company and your only rival to simultaneously submit a price quote for supplying 100,000 front and rear windshields for its newest version of the Highlander. If both you and your rival submit a low price, each firm supplies 50,000 front and rear windshields and earns a zero profit. If one firm quotes a low price and the other a high price, the low-price firm supplies 100,000 front and rear windshields and earns a profit of $11 million and the high-price firm supplies no windshields and loses $2 million. If both firms quote a high price, each firm supplies 50,000 front and rear windshields and earns a $6 million profit. Determine your optimal pricing strategy if you and your rival believe that the new Highlander is a "special edition" that will be sold only for one year. Would your answer differ if you and your rival were required to resubmit price quotes year after year and if, in any given year, there was a 60 percent chance that Toyota would discontinue the Highlander?
