If the exam is worth (only!) 15%, then the class average is worth (100-15)=85%.
The grade will then be 54*0.85+0*0.15= 45.9%
The letter grades (if any) will vary from school to school.
100 balloons × 4 Minutes = 400minutes
400minutes ÷ 5people = 80 ...so 80 minutes is your answer.
Answer:
7x+2
Step-by-step explanation:
Add x+x+2x+3x to get 7 xs or 7x. Then add -4+9-7+4 to get 2. Put 7x and 2 together to get 7x+2.
Hope it helps!
Answer:
<u>The constant is to add 1/10 to the previous term, therefore the unknown term is 5/10 or 1/2.</u>
<u>And this is the rule:</u>
<u>aₙ = aₙ₋₁ + 1/10 ⇒ a₁ = 3/10</u>
Step-by-step explanation:
Let's find the unknown term and the sequence:
1st term = 3/10
2nd term = 2/5 = 4/10
3rd term = x
4th term = 3/5 = 6/10
5th term = 7/10
<u>As we can see the constant is to add 1/10 to the previous term, therefore the unknown term is 5/10 or 1/2.</u>
<u>And this is the rule:</u>
<u>aₙ = aₙ₋₁ + 1/10 ⇒ a₁ = 3/10</u>
a₂ = a₁ + 1/10 ⇒ a₂ = 4/10 = 2/5 (Simplifying)
a₃ = a₂ + 1/10 ⇒ a₃ = 5/10 = 1/2 (Simplifying)
a₄ = a₃ + 1/10 ⇒ a₄ = 6/10 = 3/5 (Simplifying)
a₅ = a₄ + 1/10 ⇒ a₅ = 7/10
White figure Area = 128
White surface area = appro. 301
Yellow area = 320
Yellow Surface area = approx. 653
Area found with = 2πrh+2πr2
Surface Area found with = 2πrh+2πr2
You need to memorize them for tests
