Every hour, 70 people enter an office building, and 42 people leave. After how many hours will there be more than people in 140 the building? Solve the inequality 70n-42n>140
Answer:
After 6 hours there will be more than 140 people, but after 5 hours there will be exactly 140 people. I don't know if this question is meant to trick you or not.
Step-by-step explanation:
To find out, 70 - 42 = 28, 140/28 = 5 after 5 hours
70(5) - 42(5) = 350 - 210 = 140
But the question asks when will there be MORE than 140 people, after 5 hours there will be 140 people, and 140 > 140 is not true, so its after 6 hours

8=729/3
Step-by-step explanation:
The exponent is not suppost to be there so middle ones are wrong and the first one is looking for the middle of the number that is even
Answer:
[tex] s = \sqrt[3]{729} \: in[/tex]
Step-by-step explanation:
[tex] \because V= s^3 [/tex]
[tex] \implies s= \sqrt[3]{V} [/tex]
[tex]\huge \purple {\therefore s = \sqrt[3]{729} \: in} [/tex]

Answer:
x = 19
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
h is the perpendicular height and b₁ , b₂ the parallel bases
Here A = 180.5 , h = x , b₁ = 13 and b₂ = 6 , then
[tex]\frac{1}{2}[/tex] x (13 + 6) = 180.5 ( multiply both sides by 2 to clear the fraction )
x × 19 = 361 ( divide both sides by 19 )
x = 19

ANSWER: 18 blue ribbons and 12 red ribbons
Step-by-step explanation:
