The non-rounded sum is 15.579, so you’d round up to 16 since 5 and up rounds up. Hope this helps<3

The area of the triangle above will equal one half of a rectangle that is 5 units long and units wide. (Input only whole numbers
il63 [147K]

Answer:

<h2>Width of the rectangle is 2</h2>

Step-by-step explanation:

A rectangle can is made up of two right angled triangle as shown.

Since area of a rectangle = base * height

Area of one of the triangle = \frac{1}{2}\  * \ area\ of\ the\ rectangle

The length and width of the triangle will be the same as that of the rectangle i.e  5units long and 2units wide

Area of one of the triangle = \frac{1}{2}  * 5 * 2

Area of one of the triangle = 5units²

The area of the triangle above will equal one half of a rectangle that is 5 units long and 2 units wide.

The total cost of a jacket and a pair of shoes was $95.11. If the price of the jacket was $2.79 less than the pair of shoes, wha
vovangra [49]

The <em>cost of the jacket</em> purchased using the <em>System of equation</em> is $46.16

<u>Given the cost prices</u> :

  • Total cost = $95.11
  • Cost of shoes = x
  • Cost of jacket = x - 2.79

<u>We could set up an equation relating the cost of each item to the total Cost : </u>

<em>Total cost = cost of jacket + cost of shoes</em>

95.11 = x - 2.79 + x

95.11 = 2x - 2.79

95.11 + 2.79 = 2x

97.90 = 2x

x = 97.90 / 2

x = 48.95

Cost of jacket = $48.95 - 2.79 = $46.16

Therefore, Cost of jacket is $46.16

You take a three-question true or false quiz. You guess on all the questions. What is the probability that you will get a perfec
elena-14-01-66 [18.8K]
The probability that you will guess the first answer correctly  =  1/2  =  0.5
The probability that you will guess the second answer correctly  =  1/2  =  0.5
The probability that you will guess the third answer correctly  =  1/2  =  0.5

The probability that you will guess all three answers correctly is

                (0.5) x (0.5) x (0.5)  =  0.125  =  12.5% .

============================

Here are all the ways your answer sheet could wind up:
(R = a right answer.  W = a wrong answer.)

W W W 
W W R
W R W
W R R
R W W
R W R
R R W
R R R

Number of possible ways to score 0 right out of 3 questions:  1 way
Number of possible ways to score 1 right out of 3 questions:  3 ways
Number of possible ways to score 2 right out of 3 questions:  3 ways
Number of possible ways to score 3 right out of 3 questions:  1 way

Statistically, if your answers are all pure guesses, 
then on the average, the score you expect is

      (0 + 33-1/3 + 33-1/3 + 33-1/3 + 66-2/3 + 66-2/3 + 66-2/3 + 100) / 8

   =                  400 / 8

   =                      50%  .  

If you're happy with that score, great !  
Go to the movies the night before the test,
and start guessing.

The ratio of the volume of two solids is 1331:729. What is the ratio of the surface area
katovenus [111]
Volume ratio = 1331/729 which is the cube of the linear scale factor.
To find the linear scale factor, let find the cubic root of the numerator & the denominator:

∛1331 = ∛11³  = 11

&  ∛729 = ∛9³  = 9

So the linear scale is 11/9 ==> then the ratio of their surface area will be:

11²/9² ==> 121/81.
Note, if you have a linear scale, then the surface will be the square othis scale & the volume will be the cube of the linear scale
