-5(x+7)<-10
-5x-35<-10
+35. +35
-4x<25
both divided by-4
x> -6.25
i flipped the sign because I divided with a negative number. and I hope you can make -6.25 into a fraction, I can't because I don't have a calculator with me :(
Answer:
radius = 4 cm
Step-by-step explanation:
To find the length of the radius, we will follow the step below;
First, write down the formula for finding the volume of a cylinder
v=πr²h
where v is the volume of a cylinder
r is the radius and
h is the height of the cylinder
from the question given,
v=125.6 and h = 10 cm
we can now proceed to insert the values into the formula and solve for r
note that π is a constant which is equal to 3.14
v=πr²h
125.6 =3.14×r×10
125.6 =31.4 r
Divide both-side of the equation by 31.4
125.6/31.4 =31.4 r/31.4
4 = r
r =4 cm
The length of the radius = 4 cm
Answer:
because you can have 24 go into 60 2 times
Step-by-step explanation:
She only had it go in to 60 once but it should be 2 times
The rate of change is +(-1) or -1
The number of hours that should be used to study over the weekend =hrs
The number of hours to study 3 credit course is = 6hrs/ week.
The number of hours studied on monday, wednesday and friday,
= 3/5 + 16/4 +2/3
The lowest common multiple of the denominators 5, 4 and 3 = 60
=
= 316/60
Reduce to the lowest figure by dividing through with 4,
= 79/15
To detemine the extra hours to be studied over the weekend, subtract 79/15 from 6.
that is, 6/1 - 79/15
The lowest common multiple of denominators 1 and 15 = 15
=
= hrs
