Answer:

3 5/6 cups of flour

Step-by-step explanation:

You want the total amount so we add both fractions together.

1 1/2 + 2 1/3

I prefer to convert both to an improper fraction and then convert back to a mixed number, so;

1 1/2 = whole number (1) x denominator (2), add numerator (1), = 3, put this over the old denominator (2) = 3/2

2 1/3 = whole number (2) x denominator (3), add numerator (1), = 7, put this over the old denominator (3) = 7/3

Now we add the 2 improper fractions, so we have to convert them both to a common denominator. The LCM of 2 and 3 is 6, so it will be over 6.

3/2 = to get from 2 to 6, you multiply by 3, numerator (3) x 3 = 9, over 6 = 9/6.

7/3 = to get from 3 to 6, you multiply by 2, numerator (7) x 2 = 14, over 6 = 14/6.

9/6 + 14/6 = 23/6

Now we change back into a mixed number, how many times do 6 go into 23? 3 (6x3=18), as 4 would be 24.

So our whole number is 3

What is left goes over our denominator (6): 23 - 18 = 5.

So your answer is 3 5/6 cups of flour.

The probability that the dictionary is selected is 0.417, 3 novels and 2 books of poems are selected is 0.707. The probability that 4 novels are selected is 0.354.

The probability that the dictionary is selected, we need to determine the total number of ways to select 5 books from the shelf, as well as the number of ways to select the dictionary and 4 other books.

The total number of ways to select 5 books from the shelf is:

C(12,5) = 12! / (5! * 7!) = 792

The number of ways to select the dictionary and 4 other books is:

C(1,1) * C(11,4) = 11! / (4! * 7!) = 330

Therefore, the probability that the dictionary is selected is:

P(dictionary) = 330/792 = 0.417

The probability that 3 novels and 2 books of poems are selected, we need to determine the total number of ways to select 5 books from the shelf, as well as the number of ways to select 3 novels and 2 books of poems.

The total number of ways to select 5 books from the shelf is:

C(12,5) = 12! / (5! * 7!) = 792

The number of ways to select 3 novels and 2 books of poems is:

C(8,3) * C(3,2) = (8! / (3! * 5!)) * (3! / (2! * 1!)) = 560

Therefore, the probability that 3 novels and 2 books of poems are selected is:

P(3 novels, 2 books of poems) = 560/792 = 0.707

The probability that 4 novels are selected, we need to determine the total number of ways to select 5 books from the shelf, as well as the number of ways to select 4 novels and 1 other book.

The total number of ways to select 5 books from the shelf is:

C(12,5) = 12! / (5! * 7!) = 792

The number of ways to select 4 novels and 1 other book is:

C(8,4) * C(4,1) = (8! / (4! * 4!)) * (4! / (1! * 3!)) = 280

Therefore, the probability that 4 novels are selected is:

P(4 novels) = 280/792 = 0.354

Jared bought 7 cans of paint. Let the number of red paint cans that Jared bought be x. The number of black paint cans he bought would be 7 - x. A can of red paint costs $3.75 and a can of black paint costs $2.75.

He spent $22 in all. Therefore we can write:3.75x + 2.75(7 - x) = 22 Multiplying out the second term and collecting like terms gives:0.5x + 19.25 = 22Subtracting 19.25 from both sides:0.5x = 2.75Dividing by 0.5:x = 5.5Since Jared can't buy half a can of paint, we should round the answer to the nearest integer. Hence, he bought 5 cans of red paint and 2 cans of black paint. The total cost of the 5 cans of red paint would be 5 x $3.75 = $18.75.The total cost of the 2 cans of black paint would be 2 x $2.75 = $5.50.The total cost of all 7 cans of paint would be $18.75 + $5.50 = $24.25.We spent more than Jared's budget. The value of $24.25 exceeds Jared's budget of $22. Hence, there is a problem with this problem statement.

The chart shows that

It would take approximately 48.12 days for the radioactive iodide taken up and held by the thyroid to decay to 0.01% of the original amount.

To determine the time it takes for the radioactive iodide taken up by the thyroid to decay to 0.01% of the original amount, we can use the concept of radioactive decay and the half-life of iodine-131.

Half-life of iodine-131: 8.02 days

Fraction of iodide taken up by a normal thyroid: 12%

Fraction remaining after decay: 0.01% (or 0.0001) of the original amount

Let's assume we start with 100 units of radioactive iodide taken up by the thyroid. After the first half-life (8.02 days), half of the iodide will decay, so we'll have 50 units remaining. Since a normal thyroid takes up 12%, we multiply the remaining units by 0.12 to find the amount taken up: 50 units × 0.12 = 6 units.

Now, we have 6 units remaining in the thyroid, and we'll repeat the process for subsequent half-lives until we reach 0.01% of the original amount.

1st half-life: 50 units remaining (0.12 taken up)

2nd half-life: 25 units remaining (0.12 taken up)

3rd half-life: 12.5 units remaining (0.12 taken up)

4th half-life: 6.25 units remaining (0.12 taken up)

5th half-life: 3.125 units remaining (0.12 taken up)

6th half-life: 1.5625 units remaining (0.12 taken up)

After 6 half-lives, the remaining iodide in the thyroid is approximately 1.5625 units, which is 0.015625% of the original amount (100 units).

To calculate the time it takes for the radioactive iodide taken up by the thyroid to decay to 0.01% of the original amount, we need to multiply the half-life by the number of half-lives

Time = Half-life × Number of half-lives

= 8.02 days × 6

= 48.12 days

By applying algebra, it can be concluded that the number of candies remaining in the bag can be written as c = 150 - 8s, where s is the number of snacking.

Algebra is a branch of mathematics that uses symbols and mathematical operations, such as addition, subtraction, multiplication, and division to solve problems

Now we apply algebra to solve the problem:

Tyrone takes 8 pieces of candy each time snacking

After snacking 18 times, 6 pieces of candy remained in the bag

So the totals candies eaten = 8 * 18

                                              = 144 candies

Number of candies in the bag = candies eaten + remaining candies

                                                  = 144 + 6

                                                  = 150 candies

If s denotes the number of snacking, then the total number of candies eaten on s snacking = 8s

if c denotes the number of remaining candies, then:

c = total candies - candies eaten

c = 150 - 8s

Thus the number of candies remaining in the bag can be written as c = 150 - 8s, where s is the number of snacking.

To determine if the medical care system is more efficient today than in the past, we must look at the effectiveness of the system in terms of both quality and cost. In terms of quality, today's medical care has certainly improved. Healthcare professionals are more extensively trained, technology has advanced, and medical practices are more evidence-based. In terms of cost, however, it is difficult to measure efficiency. While advancements in technology and research may have improved the quality of care, they have also driven up the cost of medical care. The cost of medical care has been increasing faster than inflation and wages. It is difficult to determine if the medical care system is more efficient today than in the past without taking into account both quality and cost.

Answer:

Karen needed to put 5 gallons 3 quarts of gas into her boat on Monday and twice as much on Saturday. To convert 5 gallons 3 quarts to gallons, we can add the number of quarts to the number of gallons and convert the total to gallons. Therefore, 5 gallons 3 quarts is equal to 5 + 3/4 = 5.75 gallons. Twice as much is 2 x 5.75 = 11.5 gallons. Therefore, Karen needed a total of 5.75 + 11.5 = 17.25 gallons of gas for both days. Since she had an 18-gallon jug of gas available, she had enough gas for both days.

Therefore, the total surface area of the pyramid is 312 square inches.

To find the surface area of a pyramid, we need to find the area of the base and the area of each triangular face and then add them together.

The area of the base is 1 square foot = 12 inches x 12 inches = 144 square inches.

To find the area of each face, we need to find the area of the corresponding triangle. We know that the height of each face is 14 inches and the base of each triangle is half the base of the pyramid, which is 6 inches. Therefore, the area of each face is:

(1/2) x base x height = (1/2) x 6 inches x 14 inches = 42 square inches.

Since there are four triangular faces, the total area of the faces is 4 x 42 square inches = 168 square inches.

Therefore, the total surface area of the pyramid is:

144 square inches (base) + 168 square inches (faces) = 312 square inches.

Answer:

Step-by-step explanation:

There are 529 students standing in the assembly hall, and since there are as many students in a row as there are rows in the hall, there must be an equal number of students in each row. Therefore, each row must have 529/rows = 529/rows students in it.

The first step is to convert angle A = 23°23' to degrees. Recall, the interpretation of angle A is 23 degree 23 minutes. Also,

1 degree = 60 minutes

Let x = 23 minutes. Thus, we have these equations

1 = 60

x = 23

By crossmultiplying,

60x = 23

x = 23/60 = 0.3833

Thus,

angle A = 23 degrees + 0.3833 degrees = 23.3833 degrees

The triangle is shown below

Taking angle A as the reference angle,

hypotenuse = 42.75

opposite side = a

adjacent side = b

To find a, we would apply the sine trigonometric ratio which is expressed as

Sin# = opposite side/hypotenuse

Sin 23.3833 = a/47.25

By crossmultiplying,

a = 47.25Sin 23.3833

a = 18.75

To find b, we would apply the cosine trigonometric ratio which is expressed as

Cos# = adjacent side/hypotenuse

Cos 23.3833 = b/47.25

By crossmultiplying,

b = 47.25Cos 23.3833

b = 43.37

The given triangle is a right triangle. This means that one of its angles is 90 degrees. Thus,

angle C = 90 degrees

The sum of the angles in a traingle is 180 degrees. This means that

angle A + angle B + angle C = 180

23.3833 + angle B + 90 = 180

angle B + 113.3833 = 180

angle B = 180 - 113.3833

angle B = 66.62 degrees

The Difference in the amounts that Tsion and Ibrahim paid for their watches is £3.85.

To find the difference in the amounts that Tsion and Ibrahim paid for their watches, we need to convert the prices to the same currency. We can use the exchange rates given to convert both prices to pounds.

1 Singapore dollar = £0.58

72 Singapore dollars = 72 x £0.58 = £41.76

1 Hong Kong dollar = £0.09

399 Hong Kong dollars = 399 x £0.095 = £37.91

Therefore, Tsion paid £41.76 for the watch and Ibrahim paid £37.91 for the same model of watch.

To find the difference in the amounts paid, we can subtract the smaller amount from the larger amount:
