Step-by-step explanation:
integers are whole numbers.
3/5 is a rational number because it represents a ratio of two integers (and denominator ≠0).
Answer:
7 feet
Step-by-step explanation:
Pythagorean theorem
sqrt(4.5^2 + 5.3^2) = hypotenuse
sqrt(48.34) = hypotenuse
6.95269732 = hypotenuse
round to nearest tenth
7 feet = the length of the hypotenuse
D=m/v so d=50/10=5
The density is 5g/ml
It might be ml^3 (5g/ml^3) but I don’t remember
Answer:
(b) Circle C is shown. Line segment A C is a radius with length 7 centimeters.
Step-by-step explanation:
Given



Required
Which circle could she use
To do this, we simply calculate the areas of all the given circles
The area of a circle is:

Where


The area is calculated as thus:





The area is calculated as thus:




<em></em>

The area is calculated as thus:





The area is calculated as thus:




<em>From the calculations above; only the circle in option (b) has an area within the required range of 135 to 155cm^2</em>
It's both. Look at the gradients between one point then the one after it. It stays constant from one to the next. (Gradient is 2 by the way: (5-3)/(2-1))
