Answer:
Boys: 75%
Girls: 25%
Step-by-step explanation:
Total: 28 Students: 100%
7 Girls in clas
28(total)-7 (girls)= 21 Boys in class

If we divide the amount boys OR girls ( depending on which gender) after the toal and move the decimal to the right twice after dividing) we will get our answer.
Formula:
(Amount of Boy or girls) = x
X/28
So since we are trying to get the percentages of boys, we will replace X with the amount of boys
21/28 = .75 ( then move the decimal to the right TWICE) = 75
Then you should get your percentages: 75% Also if your lookings for girls percentages, you basically subtract 75 ( boys percentages) with the total percentages ( 100) then you should get your answer for the girls: 25%
Im assuming you are supposed to factor this problem considering there is no = sign. starting with numbers, you can factor, or divide, both of those numbers by 9. moving on to letters, both terms have a “y” attached to them, so you can take out a y as well. leaving you with the simplified equation being
9y (2x-3)
Menjawab:
15cm
Penjelasan langkah demi langkah:
Keliling segitiga adalah jumlah semua sisi segitiga
P = s1 + s2 + s3
Diberikan sisi jika segitiga;
S1 = 5cm
S2 = 7cm
S3 = 3cm
Keliling = 5cm + 7cm + 3cm
Keliling = 15cm
Oleh karena itu, keliling segitiga tersebut adalah 15 cm

===========================================================
Explanation:
Logarithms are used to solve exponential equations. Specifically if you have a variable in the exponent, then you use a log to isolate the variable.
If we set the given log expression to x, then we can rewrite it into 8^x = 1. The only value of x that works is x = 0.
------------
Or put another way,
8^x = 1
8^x = 8^0 ... replace the 1 with 8^0
x = 0 ... the bases are equal (to 8) so the exponents must be equal
------------
You can use the change of base formula to directly calculate this log
