Answer: 15
a=5, b=3
3a= 3x5= 15
You have to use a proportion.
3.5/18= 1.5/x
3.5x=27
x= 7.7 cm
True because you can put it in any order without affecting it. Example : 5 • 7 = 7 • 5. Either way they still equal 35, therefore the answer will be true.
Hope this helps :)
Answer:
mean = 0.76
median = 0.75
range = 1.79
Step-by-step explanation:
mean = sum/no of items
for media they need to be sorted: 0.05,0.06,0.75,1.10,1.84
median is the middle item, so 0.75
range = largest item - smallest item = 1.84 - 0.05 = 1.79
Answer:
a = 82
b = 130
c = 118
Step-by-step explanation:
A quadrilateral is inscribed in a circle. So, it is a cyclic quadrilateral.
Opposite angles of a cyclic quadrilateral are supplementary.
Therefore,
a° + 98° = 180°
a° = 180° - 98°
a° = 82°
a = 82
By inscribed angle theorem:
a° = 1/2(b° + 34°)
82° * 2 = b° + 34°
164° - 34° = b°
b° = 130°
b = 130
Again by inscribed angle theorem:
76° = 1/2(c° + 34°)
76° *2 = c° + 34°
152° - 34° = c°
c° = 118°
c = 118
