Answer:

c = 0.15m + 45

Step-by-step explanation:

Generally, we have the equation of a straight line as;

y = mx + b

where m is the slope and b is the y-intercept

To get the value of m, we can use the slope equation

m = (y2-y1)/(x2-x1)

Let us select two points to use from the table

we have;

(40,51) and (20,48)

So substituting these values;

m = (48-51)/(20-40) = 0.15

So we have the partially completed equation as;

y = 0.15x + b

To get the value of b, we use any of the points

Using the last, we have

51 = 0.15(40) + b

b = 45

So we have the complete equation as;

y = 0.15x + 45

using the terms in the question, we have;

c = 0.15m + 45

Answer:

11. 5:6 and 12. 5 to 6

Step-by-step explanation:

in both questions it says to simplify the boys ratio so if you have to simplify they boys then you'll have to find the GCF (Greatest common factor) of both of the number 10 and 12. And the GCF of 10 is 5, and the GCF of 12 is 6 so its 5:6

Answer:

g(h(x)) = 9x² + 12x - 3

h(g(x)) = -3x² - 19

Step-by-step explanation:

g(h(x)) = (3x² + 2)² - 7

= 9x² + 6x + 6x + 4 - 7

= 9x² + 12x - 3

h(g(x)) = 3(x² - 7) + 2

= 3x² - 21 + 2

= 3x² - 19

Answer:

(5y - 1)(5y + 1)

Step-by-step explanation:

Assuming you require the expression to be factorised.

25y² - 1 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

25y² - 1

= (5y)² - 1²

= (5y - 1)(5y + 1)

Answer:

Below.

Step-by-step explanation:

25y²-1

This is the difference of 2 squares and it factors to (5y - 1)(5y + 1).

Answer:

t = 2.5 years

Step-by-step explanation:

Given that,

Principal = $5000

Interest = $250

Rate of interest = 2%

We need to find the time. We know that,

[tex]I=\dfrac{PRT}{100}[/tex]

Put all values to find T.

[tex]T=\dfrac{100I}{PR}\\\\T=\dfrac{100\times 250}{5000\times 2}\\\\T=2.5\ yrs[/tex]

So, it will take 2.5 years.

Answer:

55 bricks

Step-by-step explanation:

First find the area of one brick by multiplying 10x6x4, which is 240 cm^3. Then divide that from 13,200 which gives you 55 bricks.

Answer:

55 bricks

Step-by-step explanation:

First, we know they used 13,200 cm^3 of concrete. cm^3 is a volume, so in order to find how many bricks can be made, we must find the volume of each brick. Multiply the dimensions of each brick. 10*6*4=240cm^3. Now, divide 13,200cm^3/240cm^3=55 bricks

There will be 25 squares will it take to fill the large square. Option C is correct.

It is defined as a two-dimensional geometry that has four sides and four vertices. The sides of the square are equal in length. It is a regular quadrilateral.

The number of squares is obtained as the relation,

=n×n

As we obtained the value of n is 5.

The number of squares will it take to fill the large square is,

=5×5

=25

Thus, there will be 25 squares will it take to fill the large square. Option C is correct.
