In a class of 24 students 13 students sold over 150 raffle tickets each and the rest of the class sold about 60 raffle tickets each. The class goal was to sell 2000 tickets. Did they reach their goal? Explain.

Answers

Answer 1

Answer: Yes.
First we need to find out what the number of the rest of the class is. 24-13 is 11. So since 13 kids sold 150 each, we would need to multiply them, that would give us 1950. Then we need to find out the total of the 11 kids that sold 60 each. 60 times 11 is 660. Then we need to add 1950 and 660. That gives us 2610 tickets. That is more than 2000, so they reach their goal.

A pan of lasagna cut into 100 servings is equally shared among a group of people. For Exercises53 – 55, determine the portion of the pan that each person receives given the number of people in
each group. Write your answer as both a fractional and a decimal part of a pan.
53. 20 people 54. 40 people 55. 30 people

Answers

53). 100 servings / 20 people = (100/20) (svngs/ppl)

   = 5 servings per person.

   Each person gets 1/20 = 5% = 0.05 of the pan.

54). 100 servings / 40 people = (100/40) (svngs/ppl)

   = 2.5 servings per person.

   Each person gets 1/40 = 2.5% = 0.025 of the pan.

55). 100 servings / 30 people = (100/30) (svngs/ppl)

      = (3 and 1/3) servings per person.

   Each person gets 1/30 = (3 and 1/3) % = 0.0333... of the pan.

4b×3b-2b=102 what is b

Answers

4b×3b-2b=102
12b^2 - 2b = 102
12b^2 - 2b - 102 = 0
divide by 2
6b^2 - b - 51
(6b + 17)(b - 3) = 0
6b + 17 = 0
6b = -17
b = -17/6 or 2 5/6
b - 3 = 0
b = 3

$4b\cdot3b-2b=102\n 12b^2-2b-102=0\n 6b^2-b-51=0\n 6b^2+17b-18b-51=0\n b(6b+17)-3(6b+17)=0\n (b-3)(6b+17)=0\n\ b=3 \vee b=-(17)/(6)$

The sum of fifteen and six times a number t is eighty one

Answers

The number is 11.

What is an equation?

"It is a mathematical statement which consists of equal symbol between two arithmetic expressions."

For given question,

the sum of fifteen and six times a number t is eighty one.

We write above statement in equation form as,

15 + 6t = 81

We solve above equation to find the number t.

⇒ 15 + 6t = 81

⇒ 15 + 6t -15 = 81 - 15 .....................(Subtract 15 from both the sides)

⇒ 6t = 66

⇒ $(6t)/(6)$ = $(66)/(6)$ ....................(Divide both the sides by 6)

⇒ t = 11

Therefore, the number is 11.
