Okay so for the #1 it says that it take 1/2 (half) a day to paint 1/4 of your bedroom and we want to know how many days it would take to paint all of the bedroom, so 4/4 of the bedroom.
We can say that
1/2(number of day) = 1/4(how much you painted)
to paint all of your room you would have to have painted 4/4 of your room
to get to 4/4 i multiplied 1/4 by 4
you do the same thing to 1/2 so 1/2•4=2
So it would take 2 days to paint all (4/4) of your bed room
I dont if im clear but just think about it
If you take half a day to pain 1/4 of your room, in one day you would’ve painted 2/4 of your room, so in one day you paint 2/4 of your room. And in 2 days you paint 4/4 of your room
Answer:
6sin^2(x) = 7 - 5cos(x)
6(1 - cos^2(x)) = 7 - 5cos(x)
6 - 6cos^2(x) = 7 - 5cos(x)
6cos^2(x) + 5cos(x) -1 = 0
(6cos(x) - 1)(cos(x) + 1) = 0
cos(x) = 1/6
x = arccos(1/6)
x = 1.40334825 + 2k*pi, 4.87983706 + 2k*pi
cos(x) = -1
x = pi + 2k*pi
Answer:
$35.70
Step-by-step explanation:
15% of 42 = 6.3
42 - 6.3 = 35.7
Answer:
Denominator
x = 12
Step-by-step explanation:
Let x be the denominator of the fraction at point y.
Given:
Point X is at 2/3 on a number line from 0.
On the same line, point y is the same point from 0.
Numerator of the fraction at point y is 8.
We need to find the denominator of the fraction at point y.
Solution:
From the above statement the distance from 0 to point X and 0 to point Y is same, so point X is equal to Y.
By cross multiplication.
Therefore, the denominator of the fraction at point y is 12.
