Answer:

32

Step-by-step explanation:

even numbers are 2,4,6,...,78

it is an A.P.

first term a=2

c.d. d=4-2=2

an=a+(n-1)d

78=2+(n-1)2

76=(n-1)2

n-1=76/2=38

n=38+1=39

now we take multiples of 10

10,20,30,...,70

70=10+(n-1)10

60=(n-1)10

n-1=60/10=6

n=6+1=7

so reqd. number of numbers=39-7=32

notka56 [123]

Answer:

Percentage score will be 83.33 %

Step-by-step explanation:

We have given Antonette gets 70 % on 10 problem test

Let consider here here total problem = total marks

So marks get 10 10 problem test = 10×0.7 = 7

Marks get in 20 problem test = 20×0.8 = 16

And marks get in 30 problem test = 30×0.9 = 27

Now total marks get get by Antonette = 7 +16 + 27 = 50

And total marks = 60

So percentage score of Antonette =\frac{50}{60}\times 100=83.33 %

pat has three pieces of fabric that measure 3/6 5/6 and 2/6 yards long . write the lengths in order from least to greatest
Harrizon [31]
The least to greatest would be 2/6, 3/6, 5/6.
As they all have the same denominator you look at the numerator to figure out the least to greatest. 2/6 is the shortest yard and 5/6 is the longest yard so it would be greater than 2/6.
