Answer:
r = 4.2 cm; d = 8.4 cm
Step-by-step explanation:
The radius is the distance from the centre of the circle to the circumference.
r = 4.2 cm
The diameter is the length of a straight line that passes through the centre with each end at the circumference.
d = 2r = 2 × 4.2 cm = 8.4 cm
Answer:
x = 8
Step-by-step explanation:
y = 4x - 2
30 = 4x - 2
+ 2 + 2
32 = 4x
/ 4 / 4
8 = x
Answer:
18/96
Step-by-step explanation:
in order to solve this we can multiply them but we have to multiply by the reciprocal of the second fraction. like this:
9/12*9/8
what i did is i flipped the second fraction and this gives us the reciprocal and allows us to just multiply across and get our answer.
hope this helps
Answer:
Negative
Step-by-step explanation:
Assume that you mean if c÷d is positive or negative when c > 0 and d < 0
c > 0 means that c is positive
d < 0 means that d is negative
positive divides negative is always negative.
Thus, c÷d is negative when c > 0 and d < 0
Answer:
N=T/ 0.5a+0.5b I belive is your answer Mate:)
Step-by-step explanation:
0.5an+0.5bn=t
n(0.5a+0.5b)=t
Step 3: Divide both sides by 0.5a+0.5b.
n=t/0.5a+0.5b
T over 0.5a+0.5b
