the size of a computer screen is measured along the diagonal. what is the approximate size measured to the nearest inch, of a 12 inch by 10.5 in computer screen

Answers

Answer 1

Answer:

In this exercise we have to use the knowledge of pythagoras and triangles to calculate the size of a canvas, in this way we find that;

$15.945 inch$

So knowing that the Pythagorean formula is given by:

$a^2=b^2+c^2$

Substituting b and c for the values informed in the exercise we find that:

$a^2=144+110.25 \n a^2=254.25 \n a=15.945$

Answer 2

Answer: This uses pythagoras which is a^2=b^2+c^2. You need to find the diagonal which is "a". Therefore a^2=144+110.25 which equals 254.25 then square root it and you get 15.945

Answers

It will cost a total amount of $4.89 to rent a movie for 7 days

Word Problem

Given Data

Cost per day = $1.39

Fee per additional day = $0.50

Number of added days = 7

Let us find the mathematical expression for the above question

Total Cost = 1.39+ 0.5*7

Total cost = 1.39+ 3.5

Total cost = $4.89

Lets just simply solve:-

Days:- 1 2 3 4 5 6 7
1.39 + 0.50 + 0.50 + 0.50 + 0.50 + 0.50 + 0.50 = Cost to rent a movie for 7 days.

1.39 + 0.50 + 0.50 + 0.50 + 0.50 + 0.50 + 0.50 = 4.39

So, to rent a movie for 7 days it would cost $4.39.

Megan has $45.12 in her purse. She spends $7.89 for lunch and $21.25 for a pair of sunglasses. Which is the best estimate for the amount of money Megan has left?Responses

$12

$16

$20

$24

Answers

Answer: To find the best estimate for the amount of money Megan has left, we need to subtract the amount she spent from the initial amount she had. Megan started with $45.12, and she spent $7.89 for lunch and $21.25 for sunglasses.

First, let's subtract $7.89 from $45.12:

$45.12 - $7.89 = $37.23

Next, let's subtract $21.25 from $37.23:

$37.23 - $21.25 = $15.98

So, the best estimate for the amount of money Megan has left is $15.98.

Out of the given options, the closest estimate to $15.98 is $16. Therefore, the correct answer is $16.

Answer:

$16

Because one side of the square is 8 (4*2), we know that the square's area is 64.

Now, we basically find the circle's area:

A=πr2 = 50.27

64 - 50.27 = 13.73

The area of the shaded region is 13.73
