Answer: 171/4, and 14.25

Step-by-step explanation:

We can solve this by first finding the area of each piece of fabric. Area is width multiplied by height, so:

3 * (4+3/4) = 57/4

We can multiply our answer by 3 again to find the total area.

57/4 * 3 = 171/4

To find the fabric as a decimal, we can first put it as a mixed fraction

$14\frac{1}{4}$

This becomes 14.25

How many 2.5 inch by 6 inch tiles will fit on a back splash that is 2.5 feet tall and 8 feet long?

Maksim231197 [3]

Area of each of the tiles = (2.5 * 6) inches^2
   = 15 inches^2
Now we have to get down to the case of the backsplash
1 feet = 12 inches
Then
Length of the back splash = 8 feet
   = (8 * 12) inches
   = 96 inches
Height of the back splash = 2.5 feet
   = (2.5 * 12) inches
   = 30 inches
Then
Area of the back splash = ( 30 * 96) inches^2
   = 2880 inches^2
So
The number of tiles required to fit in the back splash = 2880/15
   = 192
So 192 tiles will be required to fit in the back splash. I hope the procedure is clear enough for you to understand.

One term of a geometric sequence is a4=135. The common ratio is r=3. Write an explicit rule for the nth term.

Anni [7]

Answer:

$a_{n} = 5 * 3^{n-1}$

Step-by-step explanation:

To find the nth term of a geometric sequence, you have the general formula:

$a_{1} *r^{n-1}$

where a1 is the first term and r is the common ratio. In order to find the 4th term, we can substitute what we have(n is 4 because we are looking for the fourth term):

135 = $a_{1} * 3^{4 - 1}$

135 = $a_{1} * 3^3$

135 = $27a_{1}$

$a_{1} = 5$

Now, we can substitute the first term back in:

$a_{n} = 5 * 3^{n-1}$

How do i find the x and y intercepts of y = (x-3)^2 - 4<br><br> Help Would be much appreciated.

kolbaska11 [484]

Hey there!

The x-intercept would be positive 3 because it is the opposite of -3 in the equation.

And the y-intercept would be -4.

I hope this helps you :)

Given the functions a(x) = 3x − 12 and b(x) = x − 9, solve a[b(x)].

zalisa [80]

A(x) = 3x - 12
b(x) = x - 9

a(b(x)) = a(x - 9) = 3(x - 9) - 12 = 3x - 27 - 12 = 3x - 39
a(b(x)) = 3x - 39
