How do you work out the length of radius and diameter of these two circles?
bogdanovich [222]
So for the first one what you did was wrong as in wrong formula.
Radius is 5cm as it is given and diameter is double the radius which is 10.
So r=5
And D=10.

For the second one the diameter is 16cm as it is given and radius is half the diameter,so half of 16 is 8cm right?
So r=8
And D=16

At last week's track meet, Stacy ran 9/12 of a km, Jules ran 4/5 of a km, and Raul ran 3/4 of a mile. Which two students ran the
koban [17]

Answer:  No two students ran same distance

Step-by-step explanation:

Given

Stacy ran \frac{9}{12} of a km i.e.

\Rightarrow 1\times \dfrac{9}{12}=\dfrac{3}{4}=0.75\ km

Jules ran \frac{4}{5} of a km i.e.

\Rightarrow 1\times \dfrac{4}{5}=0.8\ km

Raul ran \frac{3}{4} of mile i.e.

\Rightarrow 1\times \dfrac{3}{4}=0.75\ miles\\\\\text{1 mile=1.6 km}\\\\\Rightarrow 0.75\ miles=1.2\ km

So, no two students ran the same distance.

Answer:

T,F,T,F,T

Step-by-step explanation:

1. It crosses it there becuase 4(0)-15=-15 for y

2: both top and middle answers are -23, so continuous

3: it increases over that period because the exponent keeps getting bigger

4: No, its not decreasing because -12 plugged in is far less than -23 when -2 is plugged in, meaning its increasing

5: There is no number that would cause an imaginary number or make you divide by zero, meaning all real numbers are fine.
