The cube root of 35 would be plotted on a number line A. Between 3 and 4, but closer to 3.

It should be noted that cube root of a number simply means a number that you can multiply three times that will give the original number.

In this case, the cube root of 35 will be 3.2.

This means that it's closer to 3. It's also between 3 andmd 4.

Therefore, the cube root of 35 would be plotted on a number line between 3 and 4, but closer to 3.

In conclusion, the correct option is A.

• Systematic Sampling is a probability sampling method where people or researchers select members of the population in a regular interval.

• For example, by selecting  every 17th person on the list of the population. If the population is in the random order, this can imitate the benefits of random sampling.

• Systematic sampling can help in minimizing biased samples and poor survey results. If there is a low risk for manipulation of data .

• Systematic sampling introduces certain arbitrary parameters in the data. This can cause overrepresentation or underrepresentation of patterns

In systematic sampling, members from a large population are selected according to a random starting and a fixed periodic interval.

Only stratified sampling, where the population is divided into several data, guarantees the member of each group within a population will be sampled.

Based on the coordinates of XY which are X(7, 2) and Y(2, 0), the domain and range are:

The domain of a line refers to all the points on that line that the value of the x-axis can take.

In line XY, the only two x-axis values are 7 and 2. This means that the domain is therefore (2, 7).

The range of a line on the other hand, are all the points that the value on the y-axis can take.

The actual kitchen measures 18m in width.

• In mathematics, the unitary method is used to find the necessary value by first determining the value of a single unit and then multiplying the number by the single unit value.

• For example, if a car travels 60 kilometers on three litres of gasoline, we can calculate the number of kilometers traveled on one litre of gasoline using the unitary method.

We are given that Luther drew a scale drawing of an Italian restaurant. He used a scale on which 1 millimetre equals 6 meters. We need to find the width of the kitchen if in the drawing it is 3 mm wide.

So,

Step-by-step explanation: I just did this lesson

A scale factor is a ratio between the scale of the original object in an actual sense and the prototype figure of the same object.

If the height of the actual airplane is 20m and the in the scale drawing the height is 10m.

The scale factor of the airplane is 200.

A scale factor is a ratio between the scale of the original object in an actual sense and the prototype figure of the same object.

We have

The height of the plane in scale drawing:

= 10 cm

The height of the plane in an actual airplane.

= 20 m

The scale factor of the height of the airplane:

= 20m / 10 cm

[ 1 m = 100 cm ]

= (20 x 100) cm / 10 cm

= 200

This type o problem is known as a Diamond problem

From the diamonds on the top row, it is clear that the top cell of the diamond is the product of the two side numbers and the bottom is the sum of these numbers.

I will use top for the top cell and bottom for the bottom cell, left for and right respectively for left and right cells

a. Top = 2 x 5 = 10; Bottom = 2 + 5 = 7

b. Top = -2 x -1 = 2; Bottom = -2 - 1 =  -3

c. Top = Left x Right = 8
  Bottom = Left + Right = 6.  The only two numbers that satisfy this equation are Left = 4 and Right = 2 since 4 x 2 = 8 and
4 +2 = 6
Answer to c: Left = 4, Right = 2

d We have Let unknown left be L and unknown bottom be B
We have L x  (1/2) = 4 for the product
[tex]\rm{\frac{L}{2} = 4}\\\\L = 2 x 4 = 8[/tex]

We have Bottom = Left + Right = 8 + 1/2  = [tex]8\frac{1}{2}[/tex] = 17/2
Answer to d. : Left = 8, Bottom = 17/2

e. Similar to c.

Top = Left x Right = 12;
Bottom = Left + Right = -7
12 can be 2 x 6 or 3 x 4 (same as 4 x 3) or 12 x 1. 4 and 3 are the obvious choices and since they add up to - 7 they both have to be negative
So Left = -3, Right = -4

Note: (-3) x (-4) results in +12

Expression: 4*(-12)= -48

-7-6= -13

Equivalent: -12*4= -48

The required equation for sharing the bills equally is 5x = 62.65 and each will pay $12.53

How many friends went to the restaurant altogether?

The fact that the person went with  4 friends and paid for every means that he made payments for the 5 of them and he is expected to get refund from 4 persons, in other words, in order to share bills equally, the 5 friends would have to contribute equally, which means we would divided total bills by the number of friends, which is 5 not 4 because the first person would also his part of the bills

Let x be the amount paid person, the total amount paid would be x paid person multiplied by the number of friends, 5

total amount paid=5*x

total amount paid =5x

the amount paid in dollars is $62.65

5x=62.65

x=62.65/5

Step-by-step explanation:

An identity is an equation, which is true for all values of the variables in the equation.

The time taken by the cyclist to ride from the garden city to dodge city, Kansas is 3.5 miles/hour.

Given that, a cyclist rides at a constant speed of 15 miles per hour.

We need to find at this speed how long would it take the cyclist to ride from the garden city to dodge city, Kansas.

Calculate speed, distance or time using the formula d = st, distance equals speed times time.

Now, the distance between garden city to dodge city, Kansas 52.3 miles via US-50 E.

So, time taken=52.3/15

=3.48≈3.5 miles/hour

Therefore, the time taken by the cyclist to ride from garden city to dodge city, Kansas is 3.5 miles/hour.

Circumference = 75.4

Step-by-step explanation:

Since the circles are identical, that means that the radii must be equal.

4x=3x+3

x=3

That means that radius = 12

The formula for the circumference = 2pi × radius

2pi × 12 = 24pi ≈ 75.4

Answer:

75.4 (nearest tenth)

Step-by-step explanation:

The diameter of a circle is the distance from one side of the circle to the other through the center. The diameter is the widest part of the circle.

The radius of a circle is the distance from the center to the circumference.  The radius is half the diameter of a circle.

We have been given the radius of the circle on the left:  r = 4x.

Therefore, as the diameter is twice the radius, the diameter of the circle on the left is:  d = 2(4x) = 8x

We have been given the diameter of the circle on the right:  d = 6x + 6

Equate the two diameters and solve for x:

⇒ 8x = 6x + 6

⇒ 8x - 6x = 6x + 6 - 6x

⇒ 2x = 6

⇒ 2x ÷ 2 = 6 ÷ 2

⇒ x = 3

Substitute the found value of x into one of the diameter expressions to find the diameter of both circles:

⇒ d = 8x

⇒ d = 8(3)

⇒ d = 24

Circumference of a circle

C = πd

(where d is the diameter)

Substitute the found diameter into the circumference formula:

⇒ C = πd

⇒ C = 24π

⇒ C = 75.39822...

⇒ C = 75.4 (nearest tenth)

Therefore, the circumference of each circle is 75.4 units (nearest tenth).

So nearest hundred of calories of pizza is 3384.

As it is given that its an pizza of 16 inches .

A Calorie is unit of heat used to indicate the amount of energy foods produce in the human body that is equal to 1000 calories.

Rounding means making a number simpler but keeping its value close to what it was. The result is less accurate, but easier to use. Example: 73 rounded to the nearest ten is 70, because 73 is closer to 70 than to 80.

So as we all know pizza of 16 inches contains 3384.00 calories

Answer:

x = 7, x = 10

Step-by-step explanation:

x² + 70 = 17x ( subtract 17x from both sides )

x² - 17x + 70 = 0 ← in standard form

consider the factors of the constant term (+ 70) which sum to give the coefficient of the x- term (- 17)

the factors are - 10 and - 7 , since

- 10 × - 7 = + 70 and - 10 - 7 = - 17 , then

(x - 10)(x - 7) = 0 ← in factored form

equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

x - 10 = 0 ⇒ x = 10
