You can use proportions.
22.5/100 = 18/x
cross multiply:
100 x 18 = 1800
1800/22.5 = 80
so now you know 80 is the 100%.
then do:
37.5/100 = x/80
cross multiply:
37.5 x 80 = 3000
3000/100 = 30
37.5% = 30
Multiply 4k to 7k. Then divide 3t-11t by 7x4. Then square root the rest
Answer:
20 + 1 + 0.9 + 0.07
Step-by-step explanation:
Given the number 21.97 ;
To wite in expanded form:
Tens ___ Unit ____ tenth ____ hundredth
2_______ 1 _______ 9_________ 7
2 = 20
1 = 1
9 = 0.9
7 = 0.07
Hence,
20 + 1 + 0.9 + 0.07
Answer:
Step-by-step explanation:
For correct questions
1 correct questions = 1 3/4 points
1 correct question = 7/4 points
Since he got 58correct questions, tgw total points he earned will be;
58 × 7/4
= 406/4
= 101.5points
For incorrect questions
1 incorrect question = -14points
22 incorrect = -14×22
22incorreft = -308points
Total points gained/lost =-308+101.5
Total points lost = -206.5
Since Nevan has a negative point of -206.5, this means that he lost.
He scored -206.5points
