4. 3x-27 = 90
3x = 63
x = 21
5. 2x+30 = 60
2x = 30
x = 15
Answer:
Step-by-step explanation:
women=85+32=117
men=70+51=121
total=117+121=238
a. P(woman)=117/238
b. P(woman or summer)=p(woman)+P(summer )-P(woman and summer)
=117/238+155/238-85/238
=187/238
c. P(woman and summer)=85/238
Answer:
Step-by-step explanation:
first of all the question is wrong 1 kilogram = 2.2046 pounds. and 1 pound = 0.4536kilogram.
if we want to convert 112lb into kilogram. we multiply it by 0.4536.
ie 112lb = 112x0.4536kg = 50.8032kg
to convert lb to kg you do this; lb x 0.4536
to convert kg to lb you do this; kg x 2.2046
Answer:
59.04°
58.31 inches
Step-by-step explanation:
The solution triangle is attached below :
Since we have a right angled triangle, we can apply trigonometry to obtain the angle ladder makes with the ground;
Let the angle = θ
Tanθ = opposite / Adjacent
Tanθ = 50/30
θ = tan^-1(50/30)
θ = 59.036°
θ = 59.04°
The length of ladder can be obtained using Pythagoras :
Length of ladder is the hypotenus :
Hence,
Hypotenus = √(adjacent² + opposite²)
Hypotenus = √(50² + 30²)
Hypotenus = √(2500 + 900)
Hypotenus = 58.309
Length of ladder = 58.31 inches
Answer:
70 times
Step-by-step explanation:
12 * 5 = 60
28 * 5 = 140
140/2 = 70
