Total= 2838
x= # of children
3x+5= # of women
4(3x+5)-3= # of men
x + (3x+5) + 4(3x+5)-3= 2838
multiply 4 by 3x+5 first
x + (3x+5) + (4*3x) + (4*5) - 3= 2838
combine like terms
4x + 5 + 12x + 20 - 3= 2838
16x + 22= 2838
subtract 22 from both sides
16x= 2816
divide both sides by 16
x= 176
ANSWER:
# Children= x= 176
# Women= 3x+5= 3(176)+5= 533
# Men= 4(3x+5)-3=4(3(176)+5)-3= 2129
CHECK:
#children + #women + #men= 2838
176 + 533 + 2129= 2838
2838= 2838
Hope this helps! :)
1 frequency is 1
2 is 3
3 is 4
4 is 3
last is 3
that's all I understand
hope it helped
Answer:
5,120 cm³
Step-by-step explanation:
Volume = Base area × height
Base area = 160 cm²
Height = 32 cm
Vol. = 160 × 32
= 5,120 cm³
Step-by-step explanation:
this is totally simple.
the formula for the area of a circle (as you can find with any search on the internet in seconds) :
A = pi×r²
r is the radius.
and once you understand even the most basics of a circle, you know that the radius is half of the diameter.
so, in our case, r = 6/2 = 3 m
the area of the circle is therefore
pi×r² = pi×3² = pi×9 m²
The red one is A-49 P-28. Orange is A-96 P-40
