Answer:

The surface area 76.32 in^2

Step-by-step explanation:

To find the surface area of a square pyramid we have to find the area of the base and the area of the sides and add them together.

Area of the base:

Since the base is a square, all we have to do is multiply 3.6 by 3.6.

3.6 * 3.6 = 12.96

The area of the base is 12.96 in^2

Area of the sides:

Since the sides are triangles, to find the area we have to multiply the length by the height and divide by 2.

3.6 * 8.8 = 31.68

31.68/2 = 15.84

The area of one of the sides is 15.84

Surface Area:

To find the surface area we have to add the area of the base and the area of the 4 sides together.

12.96 + 4(15.84)

12.96 + 63.36 = 76.32

The surface area is 76.32 in^2

During a period of 112 minutes, a music station played 40 minutes of commercials. What

Gemiola [76]

Answer:

9:5

Step-by-step explanation:

112 - 40 = 72. 112 represents the total time, but you are comparing music to commercials, so you have to subtract the commercial time from the total time.
Find the GCF of 72 and 40, which is 8.
Divide 72 and 40. The simplified ratio is 9:5.

Answer:

Sum of $\frac{7x}{x^2-4}$ and $\frac{2}{x+2}$ is $\mathbf{\frac{9x-4}{x^2-4}}$

Option B is correct answer.

Step-by-step explanation:

We need to find sum of $\frac{7x}{x^2-4}$ and $\frac{2}{x+2}$

Finding sum of $\frac{7}{x^2-4}$ and $\frac{2}{x+2}$ :

$\frac{7x}{x^2-4}+\frac{2}{x+2}$

We know that $x^2-4 =(x+2)(x-2)$

Replacing x^2-4

$\frac{7x}{(x+2)(x-2)}+\frac{2}{x+2}$

Now, taking LCM of (x+2)(x-2) and (x+2) we get (x+2)(x-2)

$=\frac{7x+2(x-2)}{(x+2)(x-2)}\\=\frac{7x+2x-4}{(x+2)(x-2)}\\=\frac{9x-4}{(x+2)(x-2)}\\=\frac{9x-4}{x^2-4}$

So, Sum of $\frac{7x}{x^2-4}$ and $\frac{2}{x+2}$ is $\mathbf{\frac{9x-4}{x^2-4}}$

Option B is correct answer.

Answer:

Step-by-step explanation:

p = 180 - [ 360 - ( 130 + 110 ) ]

= 180 - [ 360 - 240 ]

= 180 - 120

p = 60
