Dividing mixed numbers is when you take a mixed number divided by a mixed number and make then fractions. Here's an example:
(Example)~5 1/5 divided by 3 1/3
5x5=25+1=26. 26/5
3x3=9+1=10/3
26/5 divided by 10/3= 26/5 multiplied by 3/10= 78/50
Dividing Fractions is when you turn 2 fractions and make them into a multiplication problem. Here's an example:
(Example)~ 2/3 divided by 4/8
2/3 multiplied by 8/4
2/3 x 8/4= 16/12~ Which turns into 1 4/12
Ratio of Nickel to Zinc:
( 2/7 ) = ( Nickel /4.9)
Nickel = 1.4 lbs.
Ratio of Copper to Zinc:
( 9/7 ) = ( Copper /4.9)
Copper = 6.3 lbs.
Alloy = Zinc + Nickel +
Copper
Alloy = 4.9 lbs. + 1.4 lbs.
+ 6.3 lbs.
Alloy = 12.6 lbs.

Answer:
Step-by-step explanation:
Alright, lets get started.
When two secants intersects outside a circle then the measure of the angle formed is half of the positive difference of the measures of the intercepted arcs. (Please refer the diagram I have attached)
Hence the measure of ∠1 is :
∠1=
∠1=
hence the answer is 35°. : Answer
Hope it will help :)
Answer:
8
Step-by-step explanation:
Considering the given value of sum of interior angles with exclusion of one to be 1070 then we can write it as
1070=180(n-2) where n is the number of sides required here.
Making n the subject of the formula then following step by step


Therefore, the shape is octagon and it has 8 sides.
