Answer:

A) x = 94

Step-by-step explanation:

To solve this, you first need to know that the angle of the entire line is a total of 180 degrees.

Using this information, create the equation: (x) + (x - 8) = 180. Combine like terms to get 2x - 8 = 180. Add 8 to both sides to get 2x = 188. Now divide 2 from both sides to get x = 94.

Hope it helps!

75% of a number is 120. What is 40% of the number? A. 36 B. 64 C. 138 D. 225
kakasveta [241]

Answer:

B.64

Step-by-step explanation:

75% of a number is 120.

Let's take "x" be the number.

75% of x = 120

75/100 * x = 120

0.75x = 120

x = 120/0.75

x = 160

So the number is 160.

Now we have to find the 40% of the number 160.

= 40/100 * 160

= 0.4 *160

= 64

40% of the number is B.64

Thank you.

State the amplitude, period, phase shift, and vertical shift of the function h(t)= cos (t+1)
oksano4ka [1.4K]

Answer:

Option b.

Step-by-step explanation:

We can easily solve this problem by using a graphing calculator or plotting tool.

The function is

h(t) = cos (t +1)

Please, see attached picture below.

By looking at the picture, we can tell that the amplitude is equal to 1

The function has a period of T = 2π

We can see there is no vertical shift.

It has a phase shift of +1. (Which moves the graph to the left)

Option b.

a sum of RS 500 is in the form of denominators of RS5 & RS 10..if the total no. of notes is 90 ,find the no. of notes of eac
Katarina [22]
Let rs.5 denominations be x , then rs 10 denominations will be 90-x

then total amount 5x + 10(90-x) which is rs.500

 5x + 10(90-x) = 500

900 - 5x = 500
400 = 5x
therefore x = 80
          therefore no. of rs.5 is 80
no. of rs.10 is 90-x = 90-80 = 10
