Answer:
49 girls in student council. Girls:Students = 49:77
Step-by-step explanation:
7*7=49
7*4=28
49+28=77.
Step-by-step explanation:
y = (-4/9)x + 3
-4/9 is the slope of the line. the factor is x is the slope in every line equation. the slope is always the ratio y/x.
the parallel line must have the same slope, of course.
but the y-intercept will be different.
so, its line equation looks like
y = (-4/9)x + c
we use the provided point coordinates to calculate this c.
4 = (-4/9)×9 + c
4 = -4 + c
c = 8
therefore, the parallel line equation is
y = (-4/9) + 8
a perpendicular line is a line that intercepts the original line by an angle of 90 degrees.
that means that its slope switches the original x and y, and also flips the sign.
the perpendicular slope is therefore : 9/4
so, the line equation looks like
y = (9/4)x + c
again, we use the provided point coordinates to calculate c :
4 = (9/4)×9 + c
4 = 81/4 + c
16/4 = 81/4 + c
-65/4 = c
the perpendicular line equation is
y = (9/4)x - 65/4

Step-by-step explanation:
8r(8t/r)(8c/t)=512 chairs
Answer:
3x6 = 729x when ever a number has an exponnet yo have to multiply the main number to itself as many times as it says.
So in this case you had to multiply 3 by itself(3) 6 times would be
(3x) x (3x) x (3x) x (3x) x (3x) x (3x) = 729x. And of course bring the variable.
x2 So when theres a varible that is by itself for example (x) you always add a 1 in front of it. so in this case x2 would be 1x2. 1 times itself(1) 2 times would be. (1x) x (1x) = 1x
729 smaller cubes would fit inside the larger cube.
