Pencils come in packages of 20 and signs come in packages of 12 she wants to buy the same number of pencils and pens what is the least number of pencil and pen she needs to buy

Answers

Performing LCM, the least number of pencils and pens that she needs to buy are 60 pencils and 60 pens.

LCM refers to the least common multiple. The LCM of two or more numbers is the one that can divide all the numbers by the single number itself.

Pencils come in packages of 20 and pens come in packages of 12.

So, the possible lowest common multiplier is LCM of 20 and 12, and it is 60.

So she has to buy 3 packages of pencils (60/20 = 3 ) as well 5 packages of pens ( 60/12 = 5 ).

If a cantaloupe that weighs 3.0 pounds costs $3.87, approximately how much will a 2.22 pound cantaloupe cost?

Answers

Answer:[tex]1.29 * 2.22 = 2.86[/tex]

$2.86

Step-by-step explanation:

First we need to find the price per pound for the cantaloupe

[tex]3.87/3.0=1.29[/tex]

So one pound of cantaloupe costs $1.29

Now multiply the price per pound by the weight of the second cantaloupe

[tex]1.29*2.22=2.86[/tex]

So the price for a cantaloupe that weighs 2.22 lbs would be $2.86

Can someone help me solve this question? | x-9 | +7 = 8

Answers

Answer:

x = 8

x = 10

Step-by-step explanation:

lx -9l + 7 = 8

lx - 9l + 7 - 7 = 8 - 7

lx - 9l = 1

Split into a positive and a negative case.

x - 9 = 1 and - (x - 9) = 1

Add nine to both sides

x - 9 + 9 = 1 + 9

x = 10

- (x - 9) = 1

Subtract 9 from both sides

- 8 = - x

Multiply both sides by negative 1

Answers

Answer:

£440

Answer:

£440

Step-by-step explanation:

According to the question,

Daniel invests £2200 into his bank account and he receive 10% per year simple interest.

So, money he'll have after a year = 10% of 2200 = 220

Money he will have after two years = 220×2 = 440

So he will have £440 after two years

A new concrete courtyard will be 15' by 25' and will be filled to a depth of 3" (1/4 foot.) How many cubic yards, rounded to the nearest tenth, of concrete do you need?

Answers

The volume in cubic yards of concrete needed is 3.5 cubic yards

Calculating volume

From the question, we are to calculate the volume of concrete needed

From the given information,

A new concrete courtyard will be 15' by 25'

That is,

15 feet by 25 feet

Also, from the given information,

The concrete will be filled to a depth of 3" (1/4 foot.)

That is, 0.25 foot

First, we will convert the measurements to yards

NOTE: 1 foot = 1/3 yards

Thus,

15 feet = 15/3 yards = 5 yards

25 feet = 25/3 yards

0.25 foot = 0.25/3 yard = 1/12 yards

Thus,

Volume of concrete needed = 5 × 25/3 × 1/12

Volume of concrete needed = 125/36

Volume of concrete needed = 3.472 cubic yards

Volume of concrete needed ≈ 3.5 cubic yards

Hence, the volume in cubic yards of concrete needed is 3.5 cubic yards

The Jayden family eats at a restaurant that is having a 15% discount promotion. Their meal cost $78.90 before the discount, and they leave a 20% tip. If the tip applies to the cost of the meal before the discount, what is the cost of the meal?

Answers

Answer:

The 15% discount means that they only pay 100%-15% = 85% of the meal's bill.

This would cost 85% * 78.65.

However, they also have to pay a 20% tip of the meal cost.

This would cost 20% * 78.65.

Step-by-step explanation:

total Cost = (85% * 78.65) + (20% * 78.65)

= 105% * 78.65

= 1.05 * 78.65

= $82.58

Step-by-step explanation:

certain disease has an incidence rate of 0.1%. if the false negative rate is 8% and the false positive rate is 1%, compute the probability that a person who tests positive actually has the disease.

Answers

The probability that a person who tests positive is infected is 0.0843.

Suppose the incident rate of a certain disease is 0.1 %.

The false negative rate is 8 % and the false positive rate is 1 %.

For a population of 100,00

There are 0.1 % infected = 100,00 × 0.1 % = 100

The population that is not infected is:

= 100,000 - 100 = 99900

The false negative rate is 8%, so the positive rate is 100 = 8 = 92%.

The population that is infected and has a positive result is:

= 100 × 0.92 = 92

The false positive rate is 1%.

The population that is not infected but has a positive result is:

= 99900 × 0.01 = 999

Therefore, the total positive results are:

= 92 + 999 = 1091

Therefore, the probability that a person who tests positive actually is infected is:

P ( infected / positive) = 92 / 1091 = 0.0843

Hence, the probability that a person who tests positive is infected is 0.0843.
