Answer:
4.5 cm
Step-by-step explanation:
Circunference = 2π*radius = 2*3.14*radius = 6.28*radius = 28.26
so radius = 28.26/6.28 = 4.5 cm
Answer:
They are parallel
Step-by-step explanation:
They both start with y=2/3x so you know the slope is the same. The +4 and -1 are just the intercepts
Answer:
A.1 1/2
Step-by-step explanation:
just add the 1/4 and 1/4 and u get 2/4 which simplifies to 1/2 so u get 1 1/2
Y = x - 2
Ex.
y = 1 - 2
y = -1
Answer:
The number is 24
Step-by-step explanation:
Let the two digits number be ab
In real terms, this is 10a + b
So, we have that the sum of the digits subtracted from 10a + b is 18
Mathematically, we have this as;
10a + b - (a + b) = 18
10a + b - a - b = 18
9a = 18
a = 18/9
a = 2
We are also told that the digit at the units place b is double the digit at the ten’s place a
That means b = 2a
b = 2 * 2 = 4
