What is the value of x?

Answer:

  (b)  y = 4x +15; y = 10x -2

Step-by-step explanation:

It is often sufficient to check for reasonableness in the offered answers. That is the case here.

__

The offered answer choices differ in the combinations of slope. The offered slopes (x-coefficients) are 4 or 1/4, 10 or 1/10, so it is sufficient to determine if the slope is greater than 1 in each case.

The slope is the ratio of the change in y to the change in x. It will be greater than 1 if y changes by a larger number than x does.

x-values in this table change by 4-2 = 2. y-values change by 31 -23 = 8, which is more than 2. The slope is greater than 1 for the first equation. (It is 8/2 = 4.)

The first two x-values in this table differ by 0-(-1) = 1. The first two y-values differ by -2-(-12) = 10, which is more than 1. The slope is also greater than 1 for the second equation. (It is 10/1 = 10.)

The x-coefficients in the answer choices are ...

  a) 1/14, 1/10 . . . incorrect

  b) 4, 10 . . . . correct

  c) 1/4, 10 . . . . partly correct

  d) 4, 1/10 . . . . partly correct

Step-by-step explanation:

is there any value for S??

Answer:

Use the formula for surface area of a cone:

SA = π[tex]r^{2}[/tex] · πrs

'π' stands for the pi(22/7 or 3.14) and 'r' stands for the radius which is being squared. ← This will represent the area of the base of this cone.

'π' stands for the pi(22/7 or 3.14), 'r' stands for the radius, and 's' will stand for the slant height of this cone. ← This will represent the area of the lateral surface of this cone.

What we know;

Correct me if i'm wrong with these measurements.

Now plug in what you know into the formula:-

SA = π[tex]r^{2}[/tex] · πrs

SA = 3.14(3^2) · 3.14(3) · 8

Quick note: The ' ^ ' symbol stands for a power symbol, meaning that any base is raised to the power of any exponent.

Solve!

SA = 3.14(9) · 3.14(3) · 8

SA = 28.26 · 9.42 · 8

SA = (28.26 · 9.42) · 8

SA = 266.2092 · 8

SA = 2,129.6736, and rounded to the nearest whole is 2,130.

The surface area of this cone is, 2,130 square centimetres.

Answer:

22

Step-by-step explanation:

You can just use the previous terms to derive the 4th term.

3rd term: 4(2) + 2 = 10

4th term: 10(2) + 2 = 22

The 4th number in the pattern is 22 .

A pattern is a repeated arrangement of numbers, shapes, colors and so on. The Pattern can be related to any type of event or object. If the set of numbers are related to each other in a specific rule, then the rule or manner is called a pattern. Sometimes, patterns are also known as a sequence.

According to the question

Mrs. Johnson asked to form a number pattern using these rules.

rule1: Use the number 1 as the first term.

rule2:To find any other term, double the previous term and add 2

and The first two numbers in the pattern are 1 and 4

therefore ,

First term : 1

Second term : 4  (1*2+2)

Third term :   10    (4*2+2)

Fourth term :  22   (10*2+2)

Hence, the 4th number in the pattern is 22 .

Step-by-step explanation:

Given:

To find:

Therefore:

Mean Value:

[tex]\displaystyle \large{m=\dfrac{1}{n}\sum_{i =1}^n x_i \to \dfrac{x_1+x_2+x_3+...+x_n}{n}}[/tex]

Therefore:

[tex]\displaystyle \large{33=\dfrac{19+27+64+36+x}{5}}[/tex]

Solve for x - first, multiply both sides by 5 to clear out the denominator:

[tex]\displaystyle \large{33\cdot 5=\dfrac{19+27+64+36+x}{5} \cdot 5}\\\displaystyle \large{165=19+27+64+36+x}[/tex]

Evaluate the sum:

[tex]\displaystyle \large{165=146+x}[/tex]

Subtract both sides by 146:

[tex]\displaystyle \large{165-146=146-146+x}\\\displaystyle \large{19=x}[/tex]

Therefore, another value/data that will give a mean value of 33 is 19.

Answer: The following table is proportional

Step-by-step explanation:

If you see closely, you can calculate the slope of the graph (y=Mx+b)

for the first values,  the number of tickets is 5 and the cost is $40. Effectively, one ticket cost $8 (40/5). So, cou can plug this value in to the x values and check if it matches with the y- values. For sample, 10 tickets 10x8= $80, which matches the table. All these values work.

Answer:

The relationship below is proportional.

Step-by-step explanation:

As we can see to get from 5 tickets to $40 you multiply by 8.

As we can see to get from 10 tickets to $80 you multiply by 8.

As we can see to get from 15 tickets to $120 you multiply by 8.

As we can see to get from 20 tickets to $160 you multiply by 8.

So to make this into an equation we get y=8x

So the relationship is proportional.

Answer:

12x - 14y cubic yards

Step-by-step explanation:

a keyword in this is... difference

it also asks you to compare the first truck to the second truck not the second to the first

x = the amount of mulch the first truck can deliver

y = the amount of mulch the second truck can deliver

the first truck takes 12 trips so 12 trips multiplied by x (the amount of mulch the first truck can deliver) is 12x because it doesn't give us x

the second truck takes 14 trips so 14 trips multiplied by y (the amount of mulch the second truck can deliver) is 14y because it doesn't give us y

The question asks for the difference between the total number of cubic yards that the first truck carries through their 12 trips and the total number of cubic yards that the second truck carries through their 14 trips.

This gives us, 12x - 14y cubic yards

hopefully, this makes sense :)

Answer: x^2+5

Step-by-step explanation:

x is the unknown variable which is representing the number squared and then you add 5 to complete expresssion.

Answer:

x² + 5

Step-by-step explanation:

Given statement:

We know the following:

    1. "number squared" ⇒ A number multiplied to the same number.

    Let the number be known as "x". Then;

        [tex]\implies x \times x[/tex]

        [tex]\implies \underline{x^{2}}[/tex]

   2. "added to 5" ⇒ Addition between number, squared and 5.

   Let the number be known as "x". Then;

        [tex]\implies (x)^{2} + 5[/tex]  [tex](\text{number, squared} \implies x^{2} )[/tex]

        [tex]\implies \boxed{x^{2} + 5}[/tex]

Therefore, the expression that represents the statement is x² + 5.

Answer:

54cm^2

Step-by-step explanation:

You need to calculate area of the given figure. To solve this there are two figures together, triangle and rectangle.

first find area of rectangle given length = 8 cm and breadth = 4cm

therefore area of rectangle  = l * b = 8 * 4 = 32 cm^2

To find area of triangle:

The triangle itself is divided into two right angled triangle.

Now base of one right angled triangle will be 4/2 = 2cm

Area of rt. angled trangle = 1/2 * b*h = 1/2 * 2 * 11 = 11cm^2

Therefore area of whole triangle = 11*2 = 22cm^2 (since there are two rt.angled triangle)

Total area of given figure = 32 + 22 = 54 cm^2

Answer:

1. 9/24 = 0.375 ounces

You have 9 ounces of clay that make up 24 pieces therefore you need to divide the 9 by 24 to work out how much clay is used for one piece

2. X=7

To solve the equation you want x to be on its own. To do this you need to minus the 5 from the left. But what you do to one side you must do to the other so x=7 because 12-5=7

3. 3y-1

To get three times yvonnes age you need to multiple y by 3 making it 3y. You then need to take off one year which quite simply makes the expression 3y-1

4. 18/3= 6mm

You divide the total depth by the number of hours to get 6mm.

5. 3x3=9 yards

6 skirts is three times as many skirts as 2 skirts (6/2=3) and because Laura uses 3 yards for every 2 skirts you multiple 3 by 3 to get the 9 yards

Hope this helps :)
