Answers

Answer 1

Answer: 1.Subtract the number 25 from both sides then divide by 8. So 53/8
2. Subtract 48 from both sides then divide by 10 So 5.2 or 52/10
3. Subtract 5 divide by 20. So 4.75 or 95/20

Every year the library club plans an end-of-year-trip. The club usually starts fundraising at the beginning of the year to ensure it raises enough money. Ethan tells the members that anyone who is planning to go on the trip will need to sell 10 raffle tickets and 5 admission tickets at the annual fair. There are 28 members who plan to go on the trip.(a) Write two expressions showing the total amount of money the club will make if all 28 club members meet their goal. Use r to represent the price of each raffle ticket and a to represent the price of each admission ticket.

Answers

Given:
28 members
each member must sell:
10 raffle tickets
5 admission tickets

No price was specified. r is the price of each raffle ticket; a is the price of each admission ticket.

1 member :
10r + 5a

all 28 members:
28(10r + 5a)

or use distributive property of multiplication:
(28 *10r) + (28*5a)

you are charged 6% sales tax. You purchase new bicycle and pay $27 in sales tax. what is the purchase price of the bicycle

Answers

The cost of the bicycle is $450.

Percentage

A percentage is a way to describe a part of a whole. such as the $\rm{(1)/(4)$ of a pizza can be described as 25% of that pizza.

Given to us,

Sales tax = 6%

Tax given on bicycle = $27

Let the price of the bicycle be x. therefore,

6% of x = $27

$(6)/(100) * x = 27\n\nx = (27* 100)/(6)\n\nx= (2700)/(6) = 450$

Hence, the cost of the bicycle is $450.

6% is equal to 6/100 or 0.06

So, you have to pay the 27$ plus the taxes which is 6% of the 27$

0.06 x 27 = 1.62$

27+1.62 = 28.62$

PLEASE HELP with these math questions (Please don't answer if you don't know all of them)

sqrt (53) = 10 * sqrt (0.53)

0.53 = 64/121
sqrt (0.53) = sqrt (64)/ sqrt (121) = 8/11 = 0.7273
Therefore sqrt (53) = 10 * 0.7273 = 7.27

sqrt (108) = 10 * sqrt (1.08)
sqrt (1.08) = sqrt (676/625) = 26/25 = 1.04
Therefore sqrt (108) = 10 * 1.04 = 10.4

sqrt (128) = 10 * sqrt (1.28)
sqrt (1.28) = sqrt (289/225) = 17/15 = 1.133
Therefore sqrt (108) = 10 * 1.133 = 11.33

Paula caught a tarpon with a weight that was 10 times as great as the weight of a permit fish she caught . The total weight of the two fish was 132 pounds. How much did each fish weight?

Answers

x equals weight of permit fish
x + 10X = 132
11x = 132
x= 12

permit fish= 12
tarpon=120

$x \rightarrow the \ weight \ of \ permit \ fish \n 10x \rightarrow tarpon \n \n x+10x=132 \n 11x=132 \n x= (132)/(11) \n x=12 \n \n The \ weight \ of \ permit \ fish \ is \ 12. \n The \ weight \ of \ the \ tarpon \ is \ 12 *10=120 \n \n \n Checking : 12+120=132$
