If the score is 90% and the total is 70 what is the number correct ?

Answers

Answer 1

Answer: If you mean that the total number of questions is 70, then:

1. You need to figure out what 90% is of the total, 70.
2. Do this by multiplying 70 by 90% --> 70*(.9)
3. 90% of 70 is 63. The total number correct is 63.

You can check your work by figuring out what percentage 63 is of 70. 63 divided by 70 (63/70) is .9, or 90%.

While drying, apple loses 14% of its weight. How many pounds of fresh apple is needed to get 10 8/25 lbs of dried apple?

Answers

Answer:

Total fresh apple needed = 12

Step-by-step explanation:

It is given that, While drying apple loses 14% of its weight

To find the fresh apple needed

Let x be the total fresh apple needed.

Apple loses 14% of its weight. Final we need 10 8/25 lbs of dried apple

x - 14x/100 = 10 8/25

0.86x = 10 8/25

0.86x = 258/25 = 10.32

x = 12

Answer:

12lbs

Step-by-step explanation:

let x be the amount of apples you need, then:

x-0.14x= 10 8/25

0.86x = 10 8/25

(10 8/25) : 86 * 100 = x

x=12

With a principal investment of $19,200, which account will have the greatest value after 5 years? simple interest: I = P • r • t interest compounded annually is A = P (1 + r)t interest compounded quarterly: A = P (1 + )4t A. 3.6% with interest compounded annually B. 3.8% in a simple interest account C. 3.4% with interest compounded annually D. 3.2% with interest compounded quarterly

Answers

Given:
Principal: 19,200
term: 5 years

a) Interest compounded annually:
A = 19,200 (1 + 0.036)^5
A = 19,200 (1.036)^5
A = 19,200 (1.1934)
A = 22,913.28

b) Simple Interest
I = 19,200 * 0.038 * 5
I = 3,648.38

19,200 + 3,648.38 = 22,848.38

c) Interest compounded annually
A = 19,200 (1 + 0.034)^5
A = 19,200 (1.034)^5
A = 19,200 (1.182)
A = 22,694.40

d) Interest compounded quarterly
A = 19,200 (1 + 0.032/4)^4*5
A = 19,200 (1 + 0.008)^20
A = 19,200 (1.008)^20
A = 19,200 (1.173)
A = 22,521.60

Without using 10, show directly that (17.6-1)8 = 17.6-8

Answers

(x^-b)^a=x^-ab
17.6^-8

Final answer:

The given statement (17.6-1)8 = 17.6-8 is not correct when you employ the distributive property of multiplication over subtraction. The correct calculation should result in 132.8 ≠ 9.6.

Explanation:

The equation given in the question is (17.6-1)8 = 17.6-8. This equation is actually applying the distributive property of multiplication over subtraction where 'a(b-c) = ab - ac'.

In your case, 'a' is 8, 'b' is 17.6, and 'c' is 1. According to the distributive property, this should result in 8*17.6 - 8*1.

Multiplying these out gives 140.8 - 8 which equals 132.8, not 17.6-8 or 9.6. This means that (17.6-1)8 ≠ 17.6-8, and the given statement is not true.
