Answer:
x > -24
Step-by-step explanation:
18 - 3x < 90
Subtract 18 from both sides.
-3x < 72
Divide both sides by -3. (When diving by a negative, flip the sign.)
x > -24
Answer:
16m
8m
50.24m
200.96m^2
Step-by-step explanation:
13. 8*2=16
14. 8m
15. 2pi r = 2* pi* 8= 50.24
16. pi r^2 = pi * 8^2= 200.96m^2
Right triangle means we can use a^2+b^2=c^2
isosceles means 2 sides are equal legnths
the hypotenuse is normally the longest side so the equal sides are the other sides so therefore
a=b
therefor
(a^2)+(a^2)=c^2
2(a^2)=16^2
2(a^2)=256
divde both sides by 2
a^2=8
the side legnth of the other 2 sides is the square root of 8 which is aprox 2.8284271247452
but we only want the tenth so we look at the hundreths as well
2.82
round to the nearest tenth
2.8 cm is the answer of the legnths
