Answer: Number D is correct
Step-by-step explanation:
Because, they can both go in each other and, they are the opposite of each other
Answer:
x = 
Step-by-step explanation:
Using the Pythagorean Theorem we can solve this problem.
The legs of the triangle will be the same (the dashes in the middle of the line indicates they are the same).
The Pythagorean Theorem will look like this:

Now, let's find a:
The square of a radical will be whatever is under the arch
Divide 11 by 2
Square root both sides
a = 
Therefore, the length of side x is equal to
.
Hope this helps!!
Answer:
A =363 cm^2
Step-by-step explanation:
A = π r^2
r = 11.3
Rounding to the nearest whole number
r =11
pi = 3.14
Rounding to the nearest whole number
pi = 3
A = 3 * 11^2
A = 3 *121
A =363 cm^2
Answer: 45
Step-by-step explanation:
The store has to sell
45
pairs of shoes.
Explanation:
The store has a base cost of
$
1800
, the cost per pair of shoes is
$
25
. Each pair of shoes is sold for
$
65
, therefore the profit per pair of shoes is
$
65
−
$
25
=
$
40
The formula for calculating the amount that needs to be sold would look like this;
40
x
=
1800
To determine the value of
x
, we take this formula;
x
=
1800
40
x
=
45
Therefore, the store needs to sell
45
pairs of shoes to break even.
