Answer:

110/170 = 0.6471 = 64.7% or 65%

Step-by-step explanation:

                              reading |   television

Television          |    70        |    20        |        90 total for TV

___________________________________________________

Reading             |    40        |    40         |       80 total for reading

___________________________________________________

Total students   |    110        |      60       |        170 total students

Students who like BOTH are 70 + 40 = 110   percentage = part/whole = 110/170

Students who ONLY like television = 20

Students who ONLY like reading = 40

Which of the following is equivalent to Square root -63
asambeis [7]

Answer:

3i \sqrt{7}

Step-by-step explanation:

The imaginary unit is i=\sqrt{-1}.

Now 63 itself is not a perfect square but 63 does contain a factor that is.

63=9×7 and 9 is a perfect square.

So \sqrt{-63}=i \sqrt{63}.

i \sqrt{63}=i \sqrt{9 \cdot 7}=i \sqrt{9} \sqrt{7}=i(3) \sqrt{7}=3i \sqrt{7}

How to do this please tell me the amser
Mariana [72]
1.30 × 3 = 3.90

3.90 + 0.65 (half of 1.30) = 4.55

the most 104 can be devided by 4.55 with no remainders is 22

22 × 4.55 = 100.1

this leaves with 3.9$ which we can buy 3, 1.30 with

22 + 3 = 24

25 tarts is the most you can buy with 104$ leaving on remainders.

Write the equation of a line in POINT-SLOPE
Tems11 [23]

Answer:

y - 2 = 1/2(x - 3)

Step-by-step explanation:

In this question, we need to write the given information in point-slope form.

Point-slope form: y - y1 = m(x - x1)

We know that our slope is 1/2

We are also given a coordinate: (3, 2)

Plug in the information to its correct spot in the equation:

y - 2 = 1/2(x - 3)

Your point-slope form would be: y - 2 = 1/2(x - 3)
