Answer: the answer is x+8= 1
X=number of boys
y=number of girls.
We can suggest the following system of equations:
x+y=33
x/y=3/8
We solve this system of equations by substitution method.
x/y=3/8 ⇒x=3y/8
(3y/8)+y=33
least common multiple=8
3y+8y=33*8
11y=33*8
y=(33*8)/11
y=3*8
y=24
x+y=33
x+24=33
x=33-24
x=9
number of boys /total number of students=9/33=3/11
There are 9 boys and 24 girls in the class.
Answer: C: 9. since 3/11 of the students are boys.
Answer:
its whatever the exponent is
Step-by-step explanation:
Answer:
b) y - 8 is one of the factor of the given expression
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given expression y² - 16 y + 64
⇒ y² - 8 y - 8 y + 64
⇒ y ( y- 8) - 8 ( y - 8)
⇒ (y-8)(y-8)
Therefore (y -8) is one of the factor
Answer:
There are 15600 ways to pick a password
Step-by-step explanation:
We have 26 possibilities to pick a letter. So, we have 26 possibilities for the first component of the password. The second letter should be different from the first one, so we have one less possibility, giving us a total of 25, and for the third letter we have 24.
This gives us 26*25*24 = 15600 ways of picking a password.
