The Average test score start = 100%
It increases by 10%:
100% = 1
10% = 0.10
1 x 0.10 = 0.1
1 + 0.1 = 1.1
It increases by another 15%
1.1 x 0.15 = 0.165
1.1 + 0.165 = 1.265
Remember to move the place value digit to the right two spaces to make it a percentage
126.5% increase is your answer
hope this helps
Answer:
1 dollar
Step-by-step explanation:
20% = .20(percentage to decimal conversion)
.20 * 5 = 1 or 5 * .20 = 1 either way works
That looks great! But say you chose number 2. You could say you organized it by multiplying single packs by the pieces of packs.
Answer:
C. 19.
Step-by-step explanation:
Let's find the answer.
Step 1: divide the first number of 76, which is 7, by 4 and find the integer part.
7/4=1.75, so the integer part is 1.
Step 2: subtract from 7 the (integer part times 4)
7-(1*4)=3
Step 3: put toether the result (3) and the second number of 76, which is 6, so the result is 36.
Step 4: find how many times we need to add 4s to reach 36, so:
4+4+4+4+4+4+4+4+4=36 which means that:
36/4=9
Step 5: put together the two resulted numbers calculated in step 1, which is 1, and step 4, which is 9:
1 and 9 giving 19, so the answer is:
76/4=19.
In conclusion the answer is C. 19.
