Answer: 6.5 or 2/13
Step-by-step explanation: add all the numbers together first
2+8+5= 15
then add 1 purple and 1 blue together over 13 (because it says without replacement) so 2/13 then divide = 6.5
I'm pretty sure let me know if i got it wrong
Answer:
84
Step-by-step explanation:
reach triangle area is 1/2bh so
1/2(6)(4) = 12
there are 4 of them so
12x 4 = 48
then the square is 6x6 = 36
add the square to the triangle totals
48+38 = 84
Answer:
width=16
length=38
Step-by-step explanation:
perimeter of a rectangle=2(length+width)
108/2=length+ width
54=length+ width
54-width=length
also:
length-6= 2×width
length=2width +6
now you can put the length we found, in the second equation:
54-width=2width+6
54-6=2width+width
48=3width
width=16
now do the exact same thing with one of the equations we created in the beginning.
either this:
54-width=length
or this:
length=2width +6
as the 1st one is simpler, I use that:
54-(16)=length
length=38
Answer:
y=(1/4)x + 9 OR y=x/4 +9
Step-by-step explanation:
Perpendicular lines have a slope/gradient of -1/n
Because the slope of this line is -4, the slope of a line perpendicular to it would be 1/4.
y=(1/4)x+b
(0,9) is the y-intercept, so b = 9
y=(1/4)x + 9 OR y=x/4 +9
