Answer:
Step-by-step explanation:
We can immediately elimate two answers since x cannot be larger than the hypotenuse, which is 9. You can cosine = adjaent/hypotenuse, which gives the equation cos(54) = x/9, which simplifies to x = 9*cos(54). When you plug this into a calculator, you should get 5.29. Keep in mind that 54 is measured in degrees and not radians because.
Answer:
1/9
Step-by-step explanation:
h1 = 9
h2 = h1 × 1/9 = 9 × 1/9 = 1
h3 = h2 × 1/9 = 1 × 1/9 = 1/9
The hundredths place is where the 5 is.
Look to the right of the hundredths place and determine if the number is 5 or more or if the number is 4 or less.
In this problem, the number to the right of 5 is 1, and 1 is less than 4.
This means you can keep the 5 the same and every number after the 5 becomes imaginary zeroes.
3.95174 becomes 3.95 (rounded to nearest hundredth).
Answer:
Step-by-step explanation:
the way to find how many participanted in the class voted, you need to look at the percentages and the number of students that voted for Vicky.
50% of students voted for Vicky and the question later explained that the total of the 50% was 30 students. This mean we know half of the student that participated. To find the total amount of students to make 100%, you need to multiple 30 by 2. which is 60.
Now that we know there were 60 students in total, we can find how many participated by using Iverson's percentage.
this is the formula that can help with any percentage math problem:
The percentage of something ÷ 100% = the number you are looking for ÷ the total
in our case:
40÷100 = x (because it is the unknown term)÷60
from here you cross multiple getting
2400÷100x
which equals
24
now we have to add Vicky's and Iverson's voter
24 + 30= 54
60-54=6
6 students did not participate
