We can use trial or error method here...
If we take 4 table, 4*5 = 20 and 4*7 = 28. 20+28 = 48.
20 : 28 = 5 : 7
So, there are 20 boys and 28 girls in a school play and there are 8 girls more than boys.
If you look over tables and try it out, only 4 table works for the given ratio.
The answer is 350 dollars Explanation 350-(350X0.4) is 210
Answer:
Part A number 2 (see work below)
<em>*please give me brainliest lol*</em>
Step-by-step explanation:
(8r^3 + 2r^2 + 1) - (7 - 7r^3 + 3r^2)
<em>after factoring out the negative, you'll have:</em>
8r^3 + 2r^2 + 1 -7 + 7r^3 - 3r^2
<em>now we combine like terms, and your answer is:</em>
15r^3 - r^2 - 6

9x+3y=36
3y=-9x+36
y=-3x+36
For lines to be perpendicular their slopes must be negative reciprocals of each other...mathematically:
m1*m2=-1 and in this case for a line to be perpendicular to y=-3x+36 that line must have a slope of:
-3m=-1, m=1/3 so
y=x/3+b, and using point (6,2) we can solve for b, the y-intercept...
2=6/3+b
2=3+b
b=-1 so the perpendicular line passing through the point (6,2) is:
y=x/3-1 or more neatly...
y=(x-3)/3
The missing side length is 15 :]
explanation: the sides on ADEF are 3 times larger than the sides on AABC
