MULTIPLE THE 2 NUMBERS

a. The amount of money that Anthony has is £26.1.

b. The amount of money that Michelle has is £39.15.

Given the following data:

To find the amount of money each of them have:

In this exercise, we are required to translate the word problem into a mathematical (algebraic) expression and solve for the unknown variable (number):

Translating the word problem into an algebraic expression, we have;

Anthony's amount is two thirds of Michelle's amount:

[tex]A = \frac{2M}{3}[/tex]   ....equation 1

Anthony and Michelle have £65.25 between them:

[tex]A+M=65.25[/tex]   ...equation 2

Substituting eqn 2 into eqn 1, we have:

[tex]\frac{2M}{3} +M=65.25\\\\2M +3M =195.75\\\\5M = 195.75\\\\M= \frac{195.75}{5}[/tex]

M = £39.15

To find the value of A:

[tex]A = \frac{2M}{3}\\\\A = \frac{2\times39.15}{3}\\\\A = \frac{78.3}{3}[/tex]

A = £26.1

The area of the figure after dilation would be 20 square units.

Scale factor is used to compare 2 quantities, indicating by how much one quantity is greater than the other. It is denoted by K. Mathematically-

K = a/b.

If a coordinate point (x, y) is dilated by a scale factor of [k], then the coordinate point after dilation will be - (kx, ky).

Given is the 2 - D figure as shown.

Assume the length of each side as 1 units. Then after the dilation by K = 2, each side would be of 2 units. Then, the area of the figure would be -

A = 5(2 x 2) = 5 x 4 = 20 square units

Therefore, the area of the figure after dilation would be 20 square units

Answer:C

Step-by-step explanation:

Answer:

It is C. Yes, Paul used stratified random sampling.

Step-by-step explanation:

Answer:

1) The function is monotonically increasing

2) The end behavior of the function is x tends to infinity as t(x) tends infinity

3) The x and y -intercept is (0, 0)

4) The endpoint is (0, 0)

5) The domain is 0 ≤ x ≤ +∞

The range is 0 ≤ t(x) ≤ +∞

Step-by-step explanation:

1) The given function of the time for the object to hit the ground is t(x) = 1/4·√x

Where;

x = The distance from the ground

t = The time it takes for the object to hit the ground

Monotonically increasing function, we have;

A function that is continuous on [a, b] and it can be differentiated in the domain, (a, b) is monotonically increasing when df(x)/dx > 0 for all values of x in (a, b)

However, where df(x)/dx < 0 for all values of x in (a, b), the function is decreasing

Therefore, using an online tool, we have;

dt(x)/dx = d(1/4·√x)/dx = 1/8 × 1/√x

Therefore, the dt(x)/dx > 0, for 0 < x < +∞ and the function is monotonically increasing

2) The end behavior of the function as x tends to infinity, t(x) = 1/4·√x approaches infinity

3) From the end behavior, and the nature, of the function t(x) = 1/4·√x, where both variables are directly proportional, we have that the x and y -intercept =  (0, 0)

4) The endpoint is (0, 0) given that as t(x) tends to 0, x tends to 0

5) The domain is 0 ≤ x ≤ +∞

The range is 0 ≤ t(x) ≤ +∞.

Answer:

The function is monotonically increasing since the output values are continually getting larger. This also tells us that the end behavior of the function is infinity.

The x-intercept is (0,0), the y-intercept is (0,0), and the endpoint too is (0,0).

The domain of the graph is all values greater than or equal to 0, and the range is all positive output values.

Step-by-step explanation:

The angles of a  triangle  adds to 180

So x is 180-46-67=67

Answer:

21

Step-by-step explanation:

∠AHI + 67° = 180° (corresponding angles are equal)

∠AHI = 180° - 67°

∠AHI = 113°

x + ∠AHI + 46° = 180° (angle sum property of a triangle)

x + 113° + 46° = 180°

x + 159° = 180°

x = 180° - 159°

x = 21°

Answer:

54°

Step-by-step explanation:

We know that a flat line= 180° and ∠ABC is 90° which means 2x+2x+x=90°.

Therefore, 5x=90° so x=18°

18*3=54 so your answer is 54°

3x = 54°

The correct option is (C).

An angle is a form of geometrical shape, that is constructed by joining two rays to each other at their end-points. The angle can also be represented by three letters of the shape that define the angle, with the middle letter being where the angle actually is (i.e.its vertex). Angles are generally represented by Greek letters such as θ, α, β, etc.

Given,

In the figure

∠CBA = 90°

and

∠CAB + ∠CBD = 180°

Putting the value by the given figure

90° + x + 2x + 2x = 180°

5x = 180° - 90°

5x = 90°

x = 90° / 5

x = 18°

⇒ 3x = 3 × 18°

⇒ 3x = 54°

Hence, the value of 3x = 54°

Answer:

y = x + 3   or  y = 1x + 3

Step-by-step explanation:

Since we're just going to find the equation (assuming it's slope-intercept form, which is y = mx + b), our jobs will be relatively simple!

Let's start with the first step and identify the y-intercept, which is the easiest step.  

That will be (0,3), as the line intercepts the y-axis there.

Next, let's find the slope of the line using [tex]\frac{rise}{run}[/tex] or [tex]\frac{y_{2}-{y}_{1}}{x_{2}-{x}_{1}}[/tex]. Just be careful when using [tex]\frac{rise}{run}[/tex] that you correctly identify the scale the axis' are using.

For now, I'll use  [tex]\frac{y_{2}-{y}_{1}}{x_{2}-{x}_{1}}[/tex].  Let's pick two points... (0,3) and (1,4).

—> [tex]\frac{4-3}{1-0}[/tex] = [tex]\frac{1}{1}[/tex]

This will be our slope, 1.

We now have our answer, y = 1x + 3.
