help please, what is the answer?

Fabric B is a more durable fabric because it has a higher double rub rating than fabric A.

We have given that,

Researchers for a textile company carried out an experiment comparing the longevity of two new fabric blends.

An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried.

They carried out a series of usage tests, known as double rubs, on 100 pieces of each type of material.

Step-by-step explanation:

The solution is Option A

The equation of Charlene's age is 3x - 4

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let Charlene's age be C

The age of Mary is = x

Now , the equation is

Charlene's age is 4 less than 3 times Mary's age

Substituting the values in the equation , we get

C = 3 x ( Mary's age ) - 4

On simplifying the equation , we get

C = 3x - 4    be equation (1)

Therefore , the value of C is 3x - 4

Hence , the age of Charlene's age is 3x - 4

Answer:

40 and 65 respectively

Step-by-step explanation:

let no. of P 5 be x

and p 10 be y

now

x + y = 105

or, x =105 - y....(!)

again

5x + 10y = 850

or , x =( 850 - 10y)÷5....(!!)

from equation (i ) and (ii)

105 - y = (850 - 10y ) ÷ 5

or, (105 - y)5 = 850 -10 y

or, 525 - 5y = 850 - 10y

or, 10y - 5y = 850 - 525

or, 5y = 325

or, y = 65

now,

x = 105 - 65

x = 40

hence ,

P5 = 40

p10 = 65

Answer:

(2,1)

Step-by-step explanation:

When we translate to the right, we are simply adding a value to the x axis value corresponding to the units of translation

We have the translation by 1 unit, so we are to add 1 to the value of the x-coordinate

Thus, we have this as ;

(-3 + 1, 1)

= (-2,1)

When we reflect a point (x,y) over the y-axis, its new coordinates become (-x,y)

Applying this to what we have above, the coordinate of the final point will be (2,1)

B: 8

Step-by-step explanation:

The area of the two smaller squares equals the area of the big square so find the area to the big square

17 * 17 = 289

289 - 225 = 64

The square root of 64 is 8 so the answer is 8.

Answer:

- 7y +3 =-25

-7y=-25—3

-7y=-28

-7y÷-7= -28÷-7

y=4

Step-by-step explanation:

Take +3 to the side so that your variable and a constant is on their own sides. When a number goes over the equals sign the sign changes at becomes the inverse that's why l said - 3. You now calculate - 25—3 equals 28 then divide by 7 to find y and your y is 4.

Answer:

b = 4[tex]\sqrt{3}[/tex] , c = 8

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = [tex]\frac{1}{2}[/tex] , then

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{4}{c}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

c = 8

Using Pythagoras' identity in the right triangle

b² + 4² = 8²

b² + 16 = 64 ( subtract 16 from both sides )

b² = 48 ( take the square root of both sides )

b = [tex]\sqrt{48}[/tex] = [tex]\sqrt{16(3)}[/tex] = 4[tex]\sqrt{3}[/tex]

Answer:

OK THIS IS A BIGGY....c = 8

Step-by-step explanation:

First, find b.

using the pythagorean theorem, a² + b² = c²

to find b using an angle, do b = √(c² - a²)

then, b = a * tan(β)

(β is the angle 30°)

So, b = 6.928

Then, plug it into the pythagorean theorem

4² + 6.928² = c²

16 + 47.997184 = c²

63.997184 = c²

√63.997184 = √c

c = 7.99982399806

Rounded is 8 :)

Answer:

Step-by-step explanation:

y = 2x - 2 (Linear)

Here, x = number of days

y = Total payment

Ashley paid $2 each day and gives $2 to her brother.

y = 2x²

This quadratic relation represents the total payment 'y' is twice as much as the number of days times itself.

y = 2ˣ

Exponential function represents that the total payment is twice as much as the number of days times itself.

Answer:

[tex]\mathrm{d. \csc \theta =\frac{5}{3}}[/tex]

Step-by-step explanation:

In a right triangle only, the tangent of an angle is equal to its opposite side divided by its adjacent side. If [tex]\cot\theta =\frac{4}{3}[/tex] as given in the problem, then [tex]\tan \theta =\frac{3}{4}[/tex], because [tex]\tan \theta =\frac{1}{\cot \theta}[/tex]. Therefore, the opposite side of angle theta is 3 and its adjacent side is 4. Thus, the hypotenuse of the triangle must be [tex]h=\sqrt{4^2+3^2}=\sqrt{25}=5[/tex].

The sine of an angle in a right triangle is equal to its opposite side divided by its hypotenuse.

Therefore, [tex]\sin \theta =\frac{3}{5}[/tex] (o/h) and since [tex]\sin \theta =\frac{1}{\csc \theta}[/tex], we have:

[tex]\csc \theta=\frac{1}{\sin \theta}=\frac{1}{\frac{3}{5}}=\boxed{\frac{5}{3}}[/tex]
