Answer 1
Answer:

Answer: 19/40

Step-by-step explanation:  first we need the values in the numerator, so we can multiply in X where you multiply the denominators with numerator of the other value in the equation finally we resolve simple equation between both numerator, so the numerator equations will be.

(-10) * (-3) = 30

(-8) * ( -1) = 8

then we get this values in the numerator

30 + 8 = 38

in the denominator we only need to multiply both values.

(-8) * (-10) = 80

after we divide each result between 2

numerator 38/2 = 19

denominator 80/2 = 40

after this, we can place the numerator and the denominator into the equation and we get the following result

19/40

Math question6. Marla swims twice a week. Her equipment cost her $32.85 and she has a membership to the pool for $35 plus $3.50 per visit. She can walk to the pool, so transportation is free. How much will swimming cost her for the year?
(Points : 1)
$431.85
$249.85
$396.85
$492.75

Answers

Answer: Swimming will cost $431.85 for Marla (per year).

Step-by-step explanation:

Hi, to solve this we have to calculate how many weeks are in a year:

If a year has 365 days, we have to divide it by 7 ( the number of days in a week)

So: 365 / 7  =52.14 = 52 weeks

Now, with the information given we have to multiply the number of weeks by the cost per visit multiplied by 2 ( because marla swims twice a week) and add the quipment cost ($32.85) and the membership cost ($35).

Mathematically speaking:

$3.50 x 2 x 52 w + $32.85 + $35 =

$364 + $32.85 + $35 =$431.85

In conclusion,   swimming will cost $431.85 for Marla (per year).
$431.85.  I got this by multiplying the amount of weeks in a year (52) by two to get 104.  I then multiplied that by 3.5  to get 364.  I then added 32.85 and 35 to that to get $431.85

The diagram shows three squares that are joined at vertices to form a right triangle. Which statement is true? A. The sum of the areas of Square N and Square L is equal to the area of Square K.
B. The sum of the areas of Square N and Square L is greater than the area of Square K.
C. The sum of the areas of Square N and Square K is equal to the area of Square L.
D. The sum of the areas of Square N and Square K is less than the area of Square L.

Answers

The sum of the areas of Square N and Square L is equal to the area of Square K and this can be determined by using the Pythagorean theorem.

Given :

The diagram shows three squares that are joined at vertices to form a right triangle.

The following steps can be used in order to determine which statement is true:

Step 1 - The Pythagorean theorem can be used in order to determine which statement is true.

Step 2 - According to the Pythagorean theorem, the sum of the square of the shorter sides is equal to the square of the longer side.

Step 3 - So, from the above steps, it can be concluded that the sum of the areas of Square N and Square L is equal to the area of Square K.

Therefore, the correct statement is given by option A).

the large Square above has area 9 is divided into 9 smaller squares of equal area what is the length of how strong and bold

Answers

If one square is divided into 9 smaller equal squares, then they have to be arranged in 3 lines of 3, that is 3 smaller equal squares per side of the original big square. That said, the area of the big square is equal to the multiplication of 3 small squares sides times 3 small squares sides, call x the length of the small squares.
So,
area = 9 = 3x*3x
9x^2 = 9
x^2 = 1
x = 1
therefore the smaller squares have sides of 1 unit
