7 0

Answer:

5.477

Step-by-step explanation:

Here we have to get the value √ ( x²+y² ) in this question where the values of x² and y² are given to be 20 and 10 respectively.

Let A = √ ( x²+y² ) =√(20+10) {Since the value of x² =20 and that of y² =10}

⇒ A= √30 =5.477  

Therefore, the value of  √ ( x²+y² ) is 5.477. (Answer)

Translate each equation into slope-intercept form. Then, state the slope and y-intercept . 4y=2x+20
likoan [24]

Answer:

           The slope-intercept form of the equation:  y = 0.5x + 5

           The slope:    m = 0.5

           The y-intercept:     b = 5

Step-by-step explanation:

Slope-intercept form is  y = mx + b, where m is the slope and b is y-intecept

4y = 2x + 20           {divide both sides by 4}

y = 0.5x + 5   ⇒   m = 0.5  and  b = 5

The value of x in the question
Gala2k [10]
1. 3x-10=x+70
      +10  -x
   2x=80
    x=40 

2. x+27+2x-39=180
   3x-12=180
       +12 
   3x = 180
   x = 64

3. 2x ÷ 80=5x+44
    - 2x             -44
         36= 3x 
          12=x

jenyasd209 [6]

Answer:

Volume of the cylinder is 75.43

Step-by-step explanation:

Volume of Cylinder is \pi r^{2} h

where r is base radius = 2 and h is the height = 6

(22/7) × 2² × 6

= (22/7) × 4 × 6

= (22/7) × 24

= 528/7

= 75.43
