In a given triangle, the sum of every angle is always
. Here, we are given a right angle (
), as well as another

Answer:
80%
Step-by-step explanation:
We are told that 1,200 students wore their school colors of green and white.
Also, we are told that 300 students did not wear school colours green and white.
Thus, total number of students = 1200 + 300 = 1500
Thus;
percent of the school population who wore their school colors is; (1200/1500) × 100% = 80%
Answer:
The ratio that exist between this three elements are 25 : 19 : 13.
Step-by-step explanation:
Ratio compares one thing to another. Ratios indicate the comparison of the size of a number to another . One trick about ratio is that you can multiply or divide the ratios by same number. For example the ratio of boy to girls can be represented as 3 : 4. If you multiply the ratios by 2 you will get the ratio 6 : 8 and it still represent the same ratios of boys to girls. Ratios can be written as a fraction for example 3/4 for our example.
The cost of the unit is made up of $6.25 , $4.75 and $3.25.
$6.25 $4.75 $3.25 . Let us multiply by 100 to remove the decimals.
625 : 475 : 325 . Now let simplify the ratios by dividing through by 25.
625/25 : 475/25 : 325/25 . The simplest ratios can be written as follows
The ratios are 25 : 19 : 13.
