When you do 12 multiplied by 3 you get 36. Then you add the 12 and 36 to get 48. This is how you know it is correct.

Answer:

The length is 110.4 mm and the width is 62.1 mm.

Step-by-step explanation:

The ratio of the length to the width of the phone screen is 16:9.

Hence, let us say that the length of the screen is 16x and the width is 9x.

Due to the screen having 90 degree corners, we can apply the Pythagorean theorem to say that:

[tex]\sqrt{(16x)^{2} + (9x)^{2}} = 127 mm[/tex]

[tex]\sqrt{256x^{2} + 81x^{2}} = 127 mm[/tex]

[tex]\sqrt{337x^{2}} = 127 mm[/tex]

[tex]337x^{2} = 127^{2} mm[/tex]

[tex]x^{2} = \frac{16129}{337}[/tex]

[tex]x = 6.9[/tex]

Hence, the length is 110.4 mm and the width is 62.1 mm.

Equation of parabola: y=6x+8.

In mathematics, a parabola is a planar curve that is mirror-symmetrical and generally U-shaped. It matches a variety of seemingly dissimilar mathematical formulations, all of which identify the same curves.

A point and a line are two ways to describe a parabola a plane curve produced by a point moving so that its distance from a fixed point equals its distance from a fixed line:

Apollonius, who discovered numerous features of conic sections, is credited with the name "parabola." It signifies "application," referring to the "application of regions" notion, which, as Apollonius demonstrated, has a connection with this curve.

A banana's curving shape is quite similar to a parabola. As a result, it is one of the best instances of parabolic objects in common use.

Step-by-step explanation:

Answer:

£30

Step-by-step explanation:

The ratio is 3:4. x:40=3:4 multiplied by 10, 30:40.

There are 30 pounds in 40 euros, therefore, €40 = £30.

A ratio indicates the number of times one number contains another.

Given that, £3 is €4, therefore,

€4 = £3

€1 = £(3/4)

€40 = £(3/4)×40

€40 = £30

Hence, 40 euros is equal to 30 pounds, €40 = £30.

''6 more than the product 8 and a number x than'' will be expressed algebraically as:

Step-by-step explanation:

Translating the sentence into an algebraic expression

Let 'x' be the number

6 more than that                            8 and a number

          6+                                                  8×n

Combining it all together means:

6+8n

Thus,

''6 more than the product 8 and a number x than'' will be expressed algebraically as:

The probability that the center of the circle lies inside the region of n-gon = 1/2

Let the N point be chosen randomly on the circumference of the circle.

Let's take N as  a1, a2, a3,…….an.

Now we need to find the probability that how many centers lie inside the region of n-gon. As there will be n- sided polygons can be formed inside the circle by joining all the points.

So here are the Possible Outcome is 2. One center may lie outside the polygon and the other which lie inside the center.

But we want one which lies inside the center. So our Favorable Outcome is 1.

So the Probability = Favorable outcome \ possible outcome

                                = 1/2

The number of units that needs to be sold to earn at least $250 is 20.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

The minimum amount that needs to be earned = $250

One unit cost = $5

The amount earned in the first week = $105

Number of units = x

The number of units to sell in the second week.

150 + 5x ≥ 250

5x ≥ 250 -150

5x ≥ 100

x ≥ 20

Thus,

20 units need to be sold to earn at least $250.

Answer:

=> $2,833.47

Step-by-step explanation:

n = [lnA - lnP] / ln(1 + i)

n = [ln15000 - ln10000] / ln(1 + 0.03)

n = [9.6158 - 9.2103] / 0.0296

n = 13.70

13 years, 8 months and 12 Days

P = A / [(1 + i)n]

P = 15000 / [(1.03)4]

P = 15000 / 1.1255

P = $13,327.31

A = 10000 (1 + 0.04)5

A = $12,166.53

The amount of money you need to save to buy a car at $15,000 would be;

$15,000 - $12,166.53

The component form and magnitude of the vector is (-7, 2) and √53 option third is correct.

It is defined as the quantity that has magnitude as well as direction also the vector always follows the sum triangle law.

We have a vector shown in the picture.

The coordinate for tail = (6, 2)

The coordinate for arrow = (-1, 4)

Coordinate for vector = (-1-(6), 4-(2)) = (-7, 2)

The magnitude:

[tex]\rm M=\sqrt{(-1-6)^2+(4-2)^2}[/tex]

M = √53

Thus, the component form and magnitude of the vector is (-7, 2) and √53 option third is correct.

The linear equation to model this situation is [tex]y=1.68x+2.15[/tex]

Linear Equation is defined as the equation having degree 1. Linear equation can be of one variable or two variable and so on...

For Example : x=5 is a linear equation in one variable.

x+y=6 is a linear equation in two variable.

Fixed charge= $2.15

Charge per mile=$1.68

Let the miles travelled by the taxi be "x'

So the total charge for "x" miles= [tex]1.68x[/tex]

Let the total charge = y

Total Charge = Fixed Charge + total Charge for "x" miles

[tex]y=2.15+1.68x[/tex]

Therefore , the linear equation to model the situation is [tex]y=2.15+1.68x[/tex]
