Yes, you can check this by setting the fractions equal to eachother and cross multiplying them. In this case both are equal to 100 therefore they're the same thing

10 x 8
12 x 8

The total area to be covered is:
2 x 10 x 8 + 2 x 12 x 8

Which sequence can be defined by the recursive formula f (1) = 4, f (n + 1) = f (n) – 1.25 for n ≥ 1?

asambeis [7]

Answer:

4, 2.75, 1.5, 0.25, - 1, - 2.25, ...............

Step-by-step explanation:

Using the recursive formula with f(1) = 4, then

f(2) = f(1) - 1.25 = 4 - 1.25 = 2.75

f(3) = f(2) - 1.25 = 2.75 - 1.25 = 1.5

f(4) = f(3) - 1.25 = 1.5 - 1.25 = 0.25

f(5) = f(4) - 1.25 = 0.25 - 1.25 = - 1

f(6) = f(5) - 1.25 = - 1 - 1.25 = - 2.25

Sequence is 4, 2.75, 1.5, 0.25, - 1, - 2.25, .......

Please answer this giving brainliest and 20 points. If you say something weird i will make sure you get banned.

Katena32 [7]

Answer:

C. The value of a is the number that the x-values are multiplied by to get to the corresponding y-values. So, a = 3.

Step-by-step explanation:

Given the points (5, 15) and (-5, -15) are plotted using the equation y = a•x, this shows a proportional relationship between y and x.

Thus using any of the points, say (5, 15), x = 5, and y = 15, thus:

a = y/x = 15/5

a = 3

Therefore, the value of a, which is 3, is the number that the x-values, 5 and -5, are multiplied by to get the corresponding y-values, 15 and -15.

As we can see, if we multiply each of the x-values by 3, it will give us their corresponding y-values.

a pyramid has a volume of 1944 in and a rectangular base with the dimensions of 18 and 9 in what is the height of the pyramid

Katarina [22]

Answer:

The height is 36 in

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, a rectangular based pyramid.

Step one

Given data

Volume v = 1944 in

length of base l = 18 in

width of base w = 9 in

Height h= ?

Step two

we know that the expression for the volume of a pyramid is given as

$volume=\frac{ lwh}{3}$

substituting our given data we have

$volume = \frac{18*9*h}{3} \\volume = \frac{162h}{3} \\volume= 54h$

but volume = 1944 in therefore

$1944= 54h\\h= \frac{1944}{54} \\h= 36 in$
