Thereare 30 students in mr.holland's music class.if 30% of the students play in the school band,how many students in the class p
stiv31 [10]
9 students in the class play in the school band. 

30% of 30
Well, when doing a percentage you first turn the percentage into a decimal (move the % two units to the left). So 30% = 0.3

In math, the word of  means multiplication, so: 0.3 x 30 
Which equal 9. 

You can also turn the percentage into a fraction, it's really up to preference. 

30/100 of 30 = 3/10 of 30 = 3/10 x 30 = 3/10 x 30/1 = 9/1 or 9

SIMPLE! 30 POINTS AND I WILL GIVE BRAINLIEST
Serhud [2]
SOLUTION:

To begin with, let's establish the problem as the following:

5 + 7

An effective method to solve this problem would be to convert it into a visual representation in order to obtain a better understanding.

As attached in the diagram above, I have demonstrated the problem visually. The five red circles / dots represent the five in the problem whilst the 7 circles / dots represent the 7 in the problem. Now we must simply count each of the circles / dots to obtain the total number which would be our final answer.

We can also simply use our fingers on our hands to solve the problem by counting 5 on our fingers and then adding 7 or vice versa to obtain the final answer.

FINAL ANSWER:

Hence, through either of these two methods, we obtain the final answer to the problem as follows:

5 + 7 = 12

Hope this helps! :)
Have a lovely day! <3

Find the area. The figure is not drawn to scale. Please show work
Irina-Kira [14]

Answer:

13.8 square feet

Step-by-step explanation:

To find the area of a triangle you use the formula a = 1/2 bh

a = 1/2 (6.9) (4) = 13.8

(simplier to understand) a = 1/2 (6.9) (4) = 27.6 divided by 1/2 = 13.8
