Answer: 45 mins

Step-by-step explanation:

Maria and Anita = 30mins

this is 2/3 the time of what Maria takes

so 30 mins is 2/3 so 30 / 2/3 = 45mins

The equation as r + 2 r = 30 miles / 2 hours and the speed of faster cyclist as 10 miles per hour.

We are given that:

The distance between the two cyclist = 30 miles.

Now let the speed of one cyclist be x miles / hour.

Speed of other cyclist = 2 x miles / hour.

Now, 2 hours later they meet.

Distance covered by 1st cyclist in 2 hours = 2 x

Distance covered by 2st cyclist in 2 hours = 4 x

Equation will be:

2 x + 4 x = 30 miles

6 x = 30 miles

x = 5 miles.

Equation for the cyclist in terms of r will be :

r + 2 r = 30 miles / 2 hours

Speed of faster cyclist = 10 miles per hour.

Therefore, we get the equation as r + 2 r = 30 miles / 2 hours and the speed of faster cyclist as 10 miles per hour.

For given polygon, the value of x is 61°

In this question we have been given a polygon with five sides.

We have been given the five interior angles of the polygon.

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°

⇒ x = 61°

Therefore, for given polygon, the value of x is 61°

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.

For the installation of a decorative wall paper Tricia will need 70 ft of the border to decorate the wall of her master bedroom.

The measures of the room is 18 ft by 14 ft.

So, the length of the room (l) = 18 ft

The width of the room(w) = 15 t

As we know that, perimeter of rectangle is 2(l×w).

We will get perimeter of he room = 2l × 2w

                                                    = 2(18) × 2(14)

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.

Pakistan's GDP is 13.27 trillion rupees.

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.

By adding the laibilites together you get 1,800.

The amount of cholesterol that is in each is given as  c = 19, E = 275 and P = 9

We 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

The probability of a prime number is 1/2. 0.5. 50%.

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

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)
