Rob and Lila try to simplify 18 x 42 + (9 – 3)2. Rob simplifies the expression and gets 360. Lila simplifies it and gets 324. Which student is correct? What error did the other student make?
The result of the expression, 18 x 4² + (9 – 3)² after simplification is 324.
What is an expression?
An expression can be defined as the combination of variables and constants with two or more operations applied to it. The operation can be addition, subtraction, multiplication and division.
Simplifying the expression
The given expression is 18 x 4² + (9 – 3)²
Using the BODMAS rule, we get,
= 18 x 4² + (6)²
= 18 × 16 + 36
= 288 + 36
= 324
Lila estimated it right.
The mistake that Rob might have made would be that he must have not solved (9 – 3)² the right way and gained the wrong answer.
Hence, the result of the expression, 18 x 4² + (9 – 3)² after simplification is 324.

Consider the information about the economy of Pakistan. Note that the currency of Pakistan is the rupee.
The government purchases: 3.30 trillion of rupees.
Individuals consume: 9.50 trillions of rupees.
Individuals save: 5.44 trillions of rupees.
Businesses invest: 1.20 trillions of rupees.
Foreigners spend: 0.50 trillions of rupees to purchase Pakistani firms.
Pakistan imports: 2.13 trillions of rupees.
Pakistan exports: 1.40 trillions of rupees.
Calculate Pakistan's GDP. Assume that the values are all current and no conversions need to be made. Give your answer in terms of trillions of rupees, and round to two decimals.
Pakistan's GDP is 13.27 trillion rupees.
What is GDP?GDP is the total value of all products manufactured and goods provided within that territory during a specific period.
We have,
Government purchases = 3.30 trillion rupees.
Individuals consume = 9.50 trillion rupees.
Individuals save = 5.44 trillion rupees.
Businesses invest = 1.20 trillion rupees.
Foreigners spend =0.50 trillion rupees to purchase Pakistani firms.
Pakistan imports = 2.13 trillion rupees.
Pakistan exports = 1.40 trillion rupees
GDP is given by:
C + I + G + NX
Where,
C = Consumption
I - Investment
G - Government Purchases
NX - Net Exports = Export - Import
So,
C = 9.50
I = 1.20
G= 3.30
NX = ( 1.40 - 2.13 ) = -0.73
GDP = 9.50 + 1.20 + 3.30 - 0.73
GDP = 13.27 trillion rupees.
Thus Pakistan's GDP is 13.27 trillion rupees.

One rectangle is "framed" within another. Find the area of the shaded region if the
"frame" is 1 unit wide.
10
5
The rectangle that is shaded has an area of 18 square units.
The framed rectangle is represented by the darkened area, while the frame is shown in white.
The frame's known width is two units, and both the rectangle and the frame have the following dimensions:
width = 7 units
length = 10 units
Now, if we remove the frame, each measure will lose 2*2 units, or 4 units (because for each measure we have the frame in both sides).
As a result, the measurements for the shaded rectangle are as follows:
width = 7 units - 4 units = 3 units
length = 10 units - 4 units = 6 units.
And since the product of a rectangle's width and length determines its area, we may calculate:
A = (3 units)*(6 units) = 18 square units.

Based on the graph, estimate (to one decimal place) the average rate of change f
The estimate (to one decimal place) of the average rate of change f is 1.7
How to estimate (to one decimal place) the average rate of change f?The interval is given as
x = 1 to x = 4
This can be represented as
(a, b) = (1, 4)
From the attached graph, we have
f(1) = 2
f(4) = 7
The estimate (to one decimal place) of the average rate of change f is
Rate = [f(b) - f(a)]/[b - a]
This gives
Rate = [f(4) - f(1)]/[4 - 1]
So, we have
Rate = [7 - 2]/[4 - 1]
Evaluate
Rate = 1.7
Hence, the estimate (to one decimal place) of the average rate of change f is 1.7

A ship’s sonar detects a submarine 440 feet below a point on the ocean’s surface 600 ft dead ahead of the ship. To the nearest degree, find the angle x. hurryy!!!
The angle x to the nearest degree is 40°
Given,
The depth of submarine that a ship's sonar detects = 440 feet
The distance from submarine to ship in oceans surface = 600 feet
We have to find the angle x.
The figure is given below:
Here, we have to use the tangents definition:
That is,
tan θ = opposite side / adjacent side
Here,
tan x = 440 / 600
We want to find x,
So,
x = tan⁻¹ (440 / 600)
x = tan⁻¹ (0.73333)
x = 40.28°

Answer:
20 - i
Step-by-step explanation:
Addition of complex numbers:In complex number addition/subtraction, add the imaginary part and add the real part separately.
The error is while adding imaginary part, you have to combine the coefficients of the imaginary numbers. So, -3 +2 will give us -1. So, the result is -i.
16 - 3i + 4+ 2i = 16 + 4 -3i + 2i

When adding or subtracting expression, we add or subtract like terms.

The probability of P(4) is 1/8. 12.5%, 0.125.
The probability of a number less than 10 is 8/8. 1 , 100%
The probability of a prime number is 1/2. 0.5. 50%.
What is the probability?Probability determines the odds that a random event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The more likely the event is to happen, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.
Probability of spinning 4 = number of possible outcomes / number of sections
1/8 = 0.125 = 12.5%
Probability of spinning a number less than 8 = possible outcomes / total sections
8/8 = 1 = 100%
Probability of spinning a prime number = number of possible outcomes / total sections

By eating one egg one cupcake and one slice of pizza a child consumes 303 mg of cholesterol. if the child eats three cupcakes in four slices of pizza he or she takes in 93 mg of cholesterol. by eating two eggs in 1 cup cake a child consumes 569 mg of cholesterol. how much cholesterol is in each item?
The amount of cholesterol that is in each is given as c = 19, E = 275 and P = 9
How to solve for the cholesterolWe have to define the variables as:
E + C + P = 303
3C + 4P = 93,
we have to make pizza, P the subject
4P = 93 - 3C,
P = (93 - 3C) / 4
2E + C = 569,
2E = 569 - C
E = (567-C) / 2
We have to form the equation
(569-C)/2 + C + (93-3C)/4 = 303
We have to multiply the equation by 4
(569-C)2 + 4C + 93-3C = 1212
1138 - 2c + 4c + 93 - 3c = 1212
-C = 1212- 93 -1138
-c = -19
hence c = 19 mg for 1 cupcake
E = (569- 19)/2
275 for 1 egg
P = (93-3C)/4
P = 93 - 57 / 4
= 36 / 4
= 9 for one pizza
Hence we would have c = 19, E = 275 and P = 9
19 + 275 + 9 = 303 (proves it to be correct)

Yes, it is entirely possible for vou te retire as a millionaire. If your long-term financial goal is te retire as a millionaire and you plan to invest at least $200 per month for 40 years, what rate of return would keep you from ending up a millionaire based on the Building Wealth charts?
The rate of return that would keep the individual from ending up a millionaire based on the Building Wealth charts is 9.22%
What is most appropriate method in this case?
The most suitable approach to solve for the rate of return in this instance is to make use of a financial calculator , which requires inputs as such the monthly payments, the beginning balance which is the present value and the future value which is $1,000,000 since the individual intends to retire as a millionaire.
N=480(number of monthly payments in 40 years i.e.40*12)

We need to find the value of x.
From given figure, we can observe that the given polygon is nothing but a pentagon.
We know that the sum of all interior angles of the pentagon is 540°
⇒ 107° + 144° + 138° + x° + 90° = 540°
⇒ 479° + x° = 540°
⇒ 479° + x° - 479° = 540° - 479°
