In a triangle all the angles add up to 180  degrees.So we know that
(6x-1)+20+(x+14)= 180 
6x+x+14-1+20=180
    v        v
  7x +   13 + 20= 180
                 v
        7x + 33=180
               -33   -33
                  0     147
        7x/7    =   147/7
           x      =       21
x=21
Then you substitute:
(6x-1)       (x+14)
(6×21-1)    (21+14)
    v                  v
  126-1           35
125 degrees / 35 degrees
125+35+20=180

Help!!!!!!!!!!!!!!!!
pashok25 [27]

Answer:

If the input is n then the output f(n) will be 4n - 8.

Step-by-step explanation:

Let the input of the function is denoted by x and the output is denoted by y.

Then, two ordered pairs of the linear function i.e.(x,y) are (2,0) and (3,4).

Therefore, the relation between x and y i.e. the equation of the straight line will be given by

\frac{y - 4}{4 - 0} = \frac{x - 3}{3 - 2}

⇒ y - 4 = 4(x - 3)

⇒ y = 4x - 8

⇒ f(x) = 4x - 8

Therefore, if the input is n then the output f(n) will be 4n - 8. (Answer)

Ryobi Limited sold a set of saws to Ace Hardware. The list price was $3,800. Ryobi offered a chain discount of 8/3/1. What's the
laila [671]

Answer:  Option 'B' is correct.

Our net price will be $3357.21.

Explanation:

Since we have given that

The list price of set of saws = $3800

There are 3 successive discounts :

8%,3%,1%

So, if we apply first for 8% discount our new price becomes,

3800\times \frac{100-8}{100}=3800\times 0.92=\$3496

Now, if we apply 3% on our deducted price , our new price becomes ,

3496\times \frac{100-3}{100}=3496\times 0.97=\$3391.12

Now, we'll apply for 1% on our new deducted price , our net price becomes,

3391.12\times \frac{100-1}{100}=3391.12\times 0.99=\$3357.21

Hence, our net price will be $3357.21.

Therefore, Option 'B' is correct.

When the center of Earth is 3.8 × 105 kilometers from the center of the moon, the force of gravity between Earth and the moon is
kolezko [41]
Given:
r = 3.8x10⁵ km = 3.8x10⁸ m, the distance between the earth and moon,
F = 20.46x10²⁵ N, the gravitational force between the earth and the moon,
G = 6.674x10⁻¹¹ m³/(kg-s²), gravitational constant
M = 5.972x10²⁴ kg, the mass of the earth.

Let m = mass of the moon.
Then
F = (G*M*m)/r^2
or
m = (F*r^2)/(G*M)

In SI units,
m = [20.46×10²⁵ * (3.8×10⁸)²]/[6.674×10⁻¹¹ * 5.972×10²⁴]
    = 7.4125×10²⁸ kg

Answer:  7.4125x10²⁸ kg
