Mathematics

Vikentia [17]3 years ago

Answer:4 2/3

Step-by-step explanation:

5a-5=7+2+2a (combine like terms; 7+2=9)

5a-5=9+2a (subract 2a from both sides; 5a-2a=3a)

3a-5=9 (add 5 to both sides; 9+5=14, -5+5=0)

3a=14 (divide both sides by 3; 14/3= 4 2/3)

Sharon borrowed $750 at 12% for one year. She paid a $20 processing fee. How much will she pay in interest?
Hunter-Best [27]

Answer:

$90

Step-by-step explanation:

The principal amount in the loan taken by Sharon is $750 . Note hat the $20 processing fee is a one time cost and is not included in the interest calculation.

Annual Rate of interest offered to Sharon is 12%

Time interval for the loan transaction is 1 year.

So the interest for 1 year is given by \[Principal * Rate * Year /100\]

\[750 * 12 * 1 /100\] = $90

So, Sharon will have to pay $90 as interest for the loan amount $750 borrowed for one year at the rate 12%.

Carbon-14 has a half-life of 5,730 years. If a sample contained 70 mg originally, how much is left after 17,190 years?
kow [346]

17,190 / 5,730 = 3. This means we must divide 70mg in half 3 times

70 / 2 = 35

35 / 2 = 17.5

17.5 / 2 = 8.75

There will be 8.75 mg left after 17,190 years.

An online furniture store sells chairs for $150 each and tables for $550 each. Every day, the store can ship a maximum of 40 pie
Katen [24]

Answer:

minimum of 13 chairs must be sold to reach a target of $6500

and a max of 20 chairs can be solved.

Step-by-step explanation:

Given that:

Price of chair = $150

Price of table = $400

Let the number of chairs be denoted by c and tables by t,

According to given condition:

t + c = 30 ----------- eq1

t(150) + c(400) = 6500 ------ eq2

Given that:

10 tables were sold so:

t = 10

Putting in eq1

c = 20 (max)

As the minimum target is $6500 so from eq2

10(150) + 400c = 6500

400c = 6500 - 1500

400c = 5000

c = 5000/400

c = 12.5

by rounding off

c = 13

So a minimum of 13 chairs must be sold to reach a target of $6500

i hope it will help you! mark me as brainliest pls
