Answer:
25.
Step-by-step explanation:
Whenever you attempt to solve an equation with multiple operations, remember this: PEMDAS
- Parenthesis
- Exponentiation (exponents)
- Multiplication/Division
- Addition/Subtraction
**THIS IS THE ORDER IN WHICH YOU SHOULD SOLVE EQUATIONS WITH MULTIPLE OPERATIONS.**
First, we solve what is in parenthesis.
20+(5 x 2/5) + 3
5/1 x 2/5 = 10/5 = 2 (simplified)
Then, replace the equation with the answer.
20 + 2 + 3
Secondly, there are no exponents.
There is no multiplication nor division.
However, there is addition.
20 + 2 + 3
20 + 2 = 22
Now, we solve the remaining addition problem.
22 + 3 = 25.
Therefore, 20+(5 x 2/5) + 3 = 25.
Given:
In triangle XYZ, x = 27 cm, y = 79 cm and .
To find:
The length of z.
Solution:
In triangle XYZ, using the Law of cosine, we get
Putting the given values in the above formula, we get
Taking square root on both sides.
Approx the above value to the nearest number and side length cannot be negative. So,
Therefore, the length of z is about 102 cm.
The probability that he will choose a girl is 3/4 times.
Two because if there was seven and i take five it gives you two
Convert 45% to a decimal by dividing it by 100. It becomes 0.45.
Multiply 0.45 onto 140.
You get 63. That’s how many eggs he sold.
