Answer:

in \: day \: one \: she \: ran \: 8 \: mile s.\\ in \: day \: two \: she \: ran \: 12 \: miles.

Step-by-step explanation:

let \: the \: number \: of \: miles \: for \: the \: first \: day \: be : x \\ let \: the \: number \: of \: miles \: for \: the \: second \: day \: be : x + 4 \\ therefore \: in \: two \: days \: she \: ran \: 20 \: miles = x + (x + 4) \\ now......thats \: the \: required \: equation....... \\ if \: x + (x + 4) = 20 \: then :  \\ 2x + 4 = 20 \\ 2x = 20 - 4 \\ 2x = 16 \\ x = 8. \\ so \: in \: day \: one \: she \: ran \: 8 \: mile \\ in \: day \: two \: she \: ran \: (8 \:  + 4) \: miles = 12 \: miles

Is sin A is 7/10 what is Cos A
viva [34]

Answer:

Cos A = (√51)/ 10

Step-by-step explanation:

sin  is opposite/hypothenuse

cos is adjacent/hypothenuse

Pythagorus theorem says that c² = a² + b²

10² = 7² + b²

b² = 100 - 49

b = ±√51

It doesn't make sense for a length to be a minus number therefore, we will use +√51.

Cos A = (√51)/ 10

Easy 20 points please tell me if I got it right and if not please tell me the right answer
mash [69]

Answer:

No, you are not correct.

It should look like this:

                              Prefer colorful decorations      Prefer neutral decorations

Pay attention                           20                                                  25

to fashion

Do not pay

attention to                              72                                                      33

fashion

Step-by-step explanation:

33 is 22% of 150. In the question it states that 70% of people do not pay attention to fashion. We need to find the other 48% here. In order to do that we multiply .48 by 150. That gets us 72. To check that answer you can add both 72 and 33 and then divide by 150, which gets 70%.

To get the amount of people that prefer neutral decorations and pay attention to fashion we need to add up 20 + 72 + 33 and that equals 125. Next, we take 150 and minus 125 of it to get 25.

Y = 3x-2 estimate the value of x when y=3
jok3333 [9.3K]

Answer:

x = 5/3

General Formulas and Concepts:
<u>Algebra I</u>

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify given.</em>

y = 3x - 2

y = 3

<u>Step 2: Solve for </u><u><em>x</em></u>

  1. [Equation] Substitute in <em>y</em>:
    3 = 3x - 2
  2. [Addition Property of Equality] Add 2 on both sides:
    5 = 3x
  3. [Division Property of Equality] Divide 3 on both sides:
    5/3 = x
  4. Rewrite:
    x = 5/3

∴ the value of <em>x</em> when <em>y</em> = 3 is equal to 5/3, or approximately 1.67.
