Answer:

Answer:

35 I think I hope it is correct

Answer:

x = 10

Step-by-step explanation:

First distribute the 2 into the parentheses

2x+20 = 4x

20 = 2x

x = 10

Step-by-step explanation:

the area of a rectangle is

length × width.

our job here is to find all integer values for length and width, so that their product is 90.

that means that length and width are both factors of 90.

the factors of 90 are

1 × 90

2 × 45

3 × 30

5 × 18

6 × 15

9 × 10

10 × 9

15 × 6

18 × 5

30 × 3

45 × 2

90 × 1

the prime number grouping

is

2 45 (can't be divided by 2 anymore, so,

next prime factor)

3 15

3 5 (can't be divided by 3 anymore, so

next prime factor)

5 1 (the end)

so, besides 1 and these prime factors, the only other factors are combinations of these prime factors :

2×3 = 6

2×5 = 10

3×3 = 9

3×5 = 15

2×3×3 = 18

2×5×3 = 30

3×5×3 = 45

Answer:

A : 45

B : 22.5

second page is 4.5

third page is is 25.5

fourth page is 62.5

Answer:

25% of £90 = £22.50

25% of £18 = £4.50

85% of 30 = £25.50

15% of £24 = £3.60

Step-by-step explanation:

For some of the answers, I can see you've got the digits correct, but it is important that you add the 0 for the .5 since it is in money terms. e.g. not 4.5, but £4.50.

With percentages, it is useful to break them down into easier percentages to solve. For example, instead of thinking of 15%, think of 10% + 5%. Finding 10% of a number is easy - divide it by 10. So 10% of 24 would be 2.4. And 5% of 24 is just 10% divided by 2, because 10 divided by 2 is 5. So 5% of 24 is 2.4 divided by 2, so 5% of 24 = 1.2

10% + 5% = 15% = 2.4 + 1.2 = 3.6

And because it is in money terms, we need to add the 0, to make it:

£3.60.

Answer:

y - intercept = - 2

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

19x - 13y = 26 ( subtract 19x from both sides )

- 13y = - 19x + 26 ( divide terms by - 13 )

y = [tex]\frac{19}{13}[/tex] x - 2 ← in slope- intercept form

with y- intercept c = - 2

The y-intercept of the line equation 19x - 13y = 26 is 2.

Given that, the y-intercept of the line 19x - 13y = 26.

In Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.

The given equation can be written in standard form as

13y=19x-26

⇒ y=19/13 x-26/13

⇒ y=19/13 x-2

So, y-intercept =2

Therefore, the y-intercept of the line equation 19x - 13y = 26 is 2.

Step-by-step explanation:

The amount of paper needed to wrap the considered box which has dimension of 10 by 10 by 6 inches is 440 sq. inches

Let the three dimensions(height, length, width) be x, y,z units respectively.

The surface area of the cuboid is given by

[tex]S = 2(a\times b + b\times c + c\times a)[/tex]

A box is usually in shape of a cuboid.

For this case, its dimensions are 10 inches, 10 inches, and 6 inches.

The amount of wrapper we need is approx same as the area of its surface (assuming we're going to measure the paper needed in terms of its area).

Thus, we get:

Amount of the paper we need to wrap the considered box = surface area of that box = surface area of cuboid of dimension 10 inch by 10 inch by 6 inches = S (say), then:

[tex]S = 2(10\times 10+ 10\times 6 + 6\times 10)\\S = 440[/tex](in sq. inches)

Thus, the amount of paper needed to wrap the considered box which has dimension of 10 by 10 by 6 inches is 440 sq. inches

Answer:

Explanation:

C ∝ √y

C = k√y

If C = 12.8, y = 16

12.8 = k√16

12.8 = k(4)

k = 3.2

So the expression:

C = 3.2√y

solve for C when y = 400

C  = 3.2(√400)

C = 3.2(20)

C = 64

The expression for C in terms of y where C is directly proportional to the square root of y is C=3.2√y and the value of C at y=400 is 64.

Let there are two variables p and q

Then, p and q are said to be directly proportional to each other if

[tex]p = kq[/tex]

where k is some constant number called constant of proportionality.

This directly proportional relationship between p and q is written as

[tex]p \propto q[/tex] where that middle sign is the sign of proportionality.

In a directly proportional relationship, increasing one variable will increase another.

C is directly proportional to the square root of y. Thus, the relation can be represented with the proportionality sign as,

[tex]C\propto \sqrt{y}[/tex]

Let k is the proportionality constant. Thus, the equation can be rewritten as,

[tex]C=k \sqrt{y}[/tex]

Here, the value of  C is 12.8 and the value of y is 16. Put these values in the above equation as,

[tex]12.8=k \times\sqrt{16}\\12.8=k \times4\\k=\dfrac{12.8}{4}\\k=3.2[/tex]

Thus, the value of constant is 3.2.

The value of constant is 3.2. Thus, the expression for C in terms of y is given as,

[tex]C=3.2\sqrt{y}[/tex]

Put the value of y =400 in the above expression.

[tex]C=3.2\sqrt{400}\\C=3.2\times20\\C=64[/tex]

Thus, the expression for C in terms of y where C is directly proportional to the square root of y is C=3.2√y and the value of C at y=400 is 64.
