Mathematics
1 answer:
Evgen [1.6K]3 years ago

Answer:

It forms an AP

AP : 71 , 73 , 75 , .................. 119

a = 71

d = 2

a_n= a + (n-1)d

119 = 71 + (n-1)2

n-1 = (119 - 71)/2

n = 24

S_n = n/2 × (a + a_n)

= 24/2 × (71 + 119)

= 12 × 190 = 2280

Pie

Answer: Irrational

Step-by-step explanation:

It is irrational because you cannot multiply a number by the same number to get the square root of 2.

Pls help me this is so hard
Mama L [17]

Answer:

She is not breaking even. The discounted price is .84t, which is less than t.

Step-by-step explanation:

Retail price= 1.4

1.4×.4= .56

40% of 1.4 is .56

Subtract 40% of 1.4 from the retail price because she is marking down.

(1.4)-(.56)=.84

So the discounted price is .84t

This problem is difficult because we don't know if she sold any tea by the retail price and if she did how much did she sell.
