Answer:
<h3>
126°</h3>
Step-by-step explanation:
given <abd = 48 and <dbc = 78, hence the addition rule is true<abc = <abd + < dbc
Substituting the given values inti the formula;
< abc = 48+78
< abc = 126°
The measure of angle abc is therefore 126°
The original price is $199.94
Given:
Discounted price = 159.95
Discount rate = 20%
If the discount rate is 20%, then the price is equivalent to 80%.
To get the original price, simply divide the discount price by its corresponding percentage.
Original price = 159.95 ÷ 80% = 199.94
To check
199.94 * 20% = 39.99 * value of the discount
199.94 - 39.99 = 159.95 *discounted price
5*30 = 150
9*30 = 270
Since the ratio is 5:9 you have to multiply both numbers in the ratio by the same constant.
I just started multiplying by 10, then 20, then 30 until I got numbers that had a difference of 120.
There are 150 boys.
Setting up an equation
5x + 120 = 9x
Solve for x and then multiply the ratio by the x to get the same result.
Answer:
Step-by-step explanation:
It looks like you are missing one value in your table. You have 6 sides of the die, however only 5 outcomes. Without this, we can't get a final answer. However, I can tell you how to solve the problem.
For the experimental probability, you need to add up all the 2's and 4's. Then, divide that number by the total amount of numbers. <span />
