Answer: 14
Explanation:
90 + 76= 166
180 - 166= 14
Answer:
Rational
Step-by-step explanation:
This can be reduced to a ratio of 1/2. Numbers that can be expressed as ratios are rational.
Answer:
The slope is 0.
Step-by-step explanation:
<em>x</em> is the gradient of the line, so multiplying the slope, zero, by the gradient, <em>x</em>, would make this equal to zero.
Answer:
The perimeter or circumference of a half mirror = 37.68 cm
Step-by-step explanation:
- The diameter of circular measure = 24 cm
We know that the perimeter of a circular shape is called the 'circumference', with the formula
- Circumference of a circle = C = 2πr
When the mirror is cut into half, the diameter gets half as well.
- Thus, the diameter of a half mirror = 24/2 = 12 cm
We know that radius = r = diameter / 2 = 12/2 = 6 cm
Thus, the perimeter of half of the mirror = C = 2πr
= 2(3.14)6
= 37.68 cm
Therefore, the perimeter or circumference of a half mirror = 37.68 cm
Answer:
4/9c
Step-by-step explanation:
When dividing by fraction, multiply by its reciprocal.
so 7a/9bc × 12b/21a = 84ab/ 189abc
Simplify
84/189c
4/9c
