Complete Question

Aisha is spending a week at her family’s cottage and wants to read her favourite book, which is 400 pages long.

a) If she reads one page every 36 seconds, how many hours will it take her to read her book?

b) Suppose Aisha only reads from 10:15 a.m. to 2:10 p.m., and from 7:20 p.m. to 9:00p.m. each day, starting on Monday. On what day and at what time will she finish reading her book?

Answer:

a) 4 hours

b) Monday, 7:25 pm

Step-by-step explanation:

a) From the above question, we are told that,

She read 1 page in 36 seconds

Total number of pages in the books = 400

Hence:

1 page = 36 seconds

400 pages = x

Cross Multiply

x = 400 × 36 seconds

x = 14,400 seconds

Converting this to hours

60 seconds = 1 minute

60 minutes = 1 hour

Hence: 60 × 60 = 3600 seconds = 2 hour.

3600 seconds = 1 hour

14400 seconds = x

x = 14400/3600

x = 4 hours

Hence, it takes Aisha 4 hours to finish reading the 400 paged book

b) The number of hours between 10:15 a.m. and 2:10 p.m. is

calculated as:

2:10 pm - 10.15 am

Converting 2:10 pm to a 24 hour clock for easy calculation =

2:10 pm = 14:10 hours

Hence:

14:10 - 10:15

= 3 hours 55 minutes

Remember, from Question a, it takes Aisha 4 hours to finish reading her book and

If 10:15 a.m. to 2:10 p.m = 3 hours 55 minutes, Aisha needs 5 extra minutes to finish her book.

Therefore, she will finish reading her book at 7:25 p.m. on Monday.

Answer:

x = 3

And, y = 4

Step-by-step explanation:

x = 3

y = 4

The computation of the possible prices of the sandwiches and salads is shown below:

Let us assume the x be the cost of the sandwich

And, the y be the cost of the salad

Now

4x + 3y = $24

Here we assume  x = 3

y = 4

So

4(3) + 3(4) = $24

12 + 12 = 24

$24 = $24

Answer:

L' = (-36, 0)

Step-by-step explanation:

If the point (x, y) is dilated by a scale factor of k about the center (0, 0), then its image is the point (kx, ky)

∵ A dilation has a center (0, 0)

∵ The point L is (-4, 0)

∴ x = -4 and y = 0

∵ The scale factor of dilation is 9

∴ k = 9

→ By using the rule above

∵ kx = 9(-4) = -36

∵ ky = 9(0) = 0

∵ The image of the point L is (kx, ky)

∴ L' = (kx, ky)

∴ L' = (-36, 0)

A perimeter is a closed path that covers, surrounds, or bounds a two-dimensional shape or a one-dimensional length. The perimeter of a circle or  ellipse is called its perimeter. Frame calculus has several practical applications.

To find the perimeter of a rectangle, or  the distance, we must add the lengths of all four sides. This can be done efficiently by simply adding the length and width and  multiplying that sum by two since there are two lengths on each side. perimeter= (Length Width) × 2 is the formula for perimeter.

Answer:

x = 4

Step-by-step explanation:

(First write the equation down)

3 ( x + 4 ) = 6x

(Then use the disstributive property)

3 times x and 3 times 4

3x + 12 = 6x

(Now subtract the same values aka 3x from both sides)

3x - 3x cancels out aka is 0

6x - 3x is 3x

(You now have...)

12 = 3x

(Now you divide both sides by 3)

12/ 3 = 3x/3

12 divided by 3 is 4

the two 3s cancel out leaving you with x

(You now have your answer)

4 = x

(Write it in proper format)

x = 4

All done, hope this helps! :)

Step-by-step explanation:

Jocelyn

A = p × e^rt

Where,

P = principal = $56000

e = Napier's number = 2.7283

r = interest rate = 7 3/8% = 0.07375

t = time = 13 years

A = 56,000 × 2.7283^(0.07375×13)

= 56,000 × 2.7283^0.95875

= 56,000 × 2.6177

= 146,591.2

Approximately

A = $146,591 to the nearest dollar

Oliver

= 56,000(1.0060)^156

= 56,000(2.5426)

Answer:

99.7%

Step-by-step explanation:

we start by getting the z-scores for the values given

We can get the z-scores using the formula below;

z-scores = (x-mean)/SD

for 338.5;

z = (338.5-598.4)/86.7 = -2.99 approximately-3

for 858.5;

z = (858.5-598.4)/86.7 = 3

so we want to get the percentages that lie within 3 standard deviations from the mean

According to the empirical rule, the percentages within 3 SD of the mean is;

100-0.15-0.15 = 99.7%

Answer:

The Binomial Theorem (a+b)2 (a+b)(a+b) a2 +2ab + b2

Answer:

Let's define:

C = number of pandesal with cheese that you sell

U = number of pandesal with ube that you sell.

If you sell these numbers of each, the total profit you get is:

C*8.00 pesos + U*9.00 pesos.

And yo want to get at least 180 pesos, then:

C*8.00 pesos + U*9.00 pesos ≥ 180 pesos.

And you also want to sell two of each, then:

C ≥ 2

U ≥2

So the system of inequalities is:

C*8.00 pesos + U*9.00 pesos ≥ 180 pesos.

C ≥ 2

U ≥2

If U is on the x-axis, and C is on the y-axis, then the graph is: (where the region at the right of the vertical line should be shaded)

Plotting the inequalities above using geogebra online graphing tool.

Let x represent the number of pandesal with cheese and y represent the number of ube with cheese

Since at least two of each kind is needed to be sold, hence:

x > 2, y > 2

At least 180 pesos worth of pandesal is needed to be sold, hence:

8x + 9y > 180

Answer:

x = 12

Step-by-step explanation:

-17x = -204 (Given)

x = 12 (division)

Negative x negative = positive

The equivalent value of the expression is x = 12

Given data ,

Let the equation be represented as A

Now , the value of A is

-17x = -204

On simplifying the equation , we get

-17x = -204

So , the left hand side of the equation is equated to the right hand side by the value of ( -204 )

Opening the parenthesis on both sides , we get

-17x = -204

Divide by ( -17 ) on both sides , we get

x = -204 / -17

x = 204 / 17

On further simplification , we get

x = 12

Therefore , the value of x = 12

Hence , the expression is x = 12

Step-by-step explanation:

The first part of the ratio would be 156. The second part of the ratio would be 52.

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other

To divide £208 in the ratio 3:1, you can use the following method:

Convert the ratio to a fraction by dividing the first number by the sum of the numbers in the ratio (3 / (3+1) = 3/4)

Multiply the fraction by the total amount you want to divide (£208)

The result will be the amount for the first part of the ratio, and the remaining amount is the second part of the ratio.

So the first part of the ratio would be: 3/4 × 208 = 156

The second part of the ratio would be: 208 - 156 = 52
