Answer:

A : 1/4

B : 19/100

C : 3/50

Step-by-step explanation:

There are 25 prime numbers from 1 to 100.

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, and 97.

25/100 = 1/4

There are 19 numbers that contain 9.

9, 19, 29, 39, 49, 59, 69, 79, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, and 99.

19/100

There are 6 numbers that are prime and contain 9.

19, 29, 59, 79, 89, 97.

6/100 = 3/50

Write an equivalent expression to present patricia total earnings this week 7h + 135 + 5h = ?h + ?

Paul [167]

Answer: 12 h + 135

Step-by-step explanation: 7h +135 + 5h = ?h + ?

7h +5h +135

=12h +135

So u combine like terms together which are 7h and 5h which gives you 12 h.And then you have 135 left,so you add 12h to 135.

Ps.If you don't know what like terms are.I will explain down below.

Like terms are variable that are the same.For an example 4y and 3y are like terms .Another example is 1/3 xy and 6xy .

What is a theory in science

alina1380 [7]

A scientific theory is a validated explanation of some aspect of the natural world, based on multiple facts that have been frequently verified through research and experimentation. Fact theories are not "guesses" but reliable accounts of the real world.

What is the value of i ^20+1?

matrenka [14]

Hey Mattchance666,

Lets solve this equation together,

The question we are enquiring is : What is the value of i ^20+1?

To solve this equation: we have to use the Power Reduction Rule.

Where I^n=I{n mod 4}<span>

</span>In this case: <span>I^20 = I^{5*4+0}=I^0</span>

1 + 1 = 2

Hope this helps,

1. Find the midpoint of the line segment joining the two points (4,-3) and (12, 3).

Mamont248 [21]

The mid-point is (8,0)

Further explanation:

A mid-point is the point on the line which divides the line in two equal segments

The formula for mid-point is:

$(x_m, y_m) = (\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2})$

Where (x1,y1) are the coordinates of first point and (x2,y2) are the coordinates of second point.

Here,

(x1, y1) = (4,-3)

(x2,y2) = (12,3)

So,

$(x_m, y_m) = (\frac{4+12}{2} ,\frac{-3+3}{2})\\(x_m, y_m) = (\frac{16}{2} , \frac{0}{2})\\ (x_m, y_m) = (8,0)$

The mid-point is (8,0)
