for 7

Yes it is right cuz 16 is the double of 8 and even the price if doubled up so the price is right

for 8

Apply the formula

2\sqrt{\frac{Area}{\pi } }

2\sqrt{\frac{154}{\pi } }

2\sqrt{49.02}

2(7)

the diameter is 14

Hope this helps :)

-4.8=1.2s+2s+4<br><br><br>Please help me <br>​
nikdorinn [45]
Simplify both sides of the equation
-4.8=1.2s+2s+4
Combine like terms
-4.8=(1.2s+2s)+(4)
-4.8=3.2s+4
Flip the equation
3.2s+4=-4.8
Subtract both sides by 4
3.2s+4-4=-4.8-4
3.2s=-8.8
Divide both sides by 3.2
3.2s/3.2= -8.8/3.2
S=-2.75 will be the answer hope it helps

what is the equation, in slope- intercept form, of the line that contains the points (-3,4) and (5,7)
gavmur [86]

Answer:

y = \frac{3}{8} x + \frac{41}{8}

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

To calculate the slope use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (5, 7)

m = \frac{7-4}{5+3} = \frac{3}{8}, hence

y = \frac{3}{8} x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

using (5, 7 ), then

7 = \frac{15}{8} + c ⇒ c = 7 - \frac{15}{8} = \frac{41}{8}

y = \frac{3}{8} x + \frac{41}{8} ← equation in slope-intercept form

Find the solution of<br> m(-11 + m) = 0
zhuklara [117]

i tried ;w;

Step-by-step explanation:

m(−11+m)=0

Step 1: Simplify both sides of the equation.

m2−11m=0

Step 2: Factor left side of equation.

m(m−11)=0

Step 3: Set factors equal to 0.

m=0 or m−11=0

m=0 or m=11

Answer:

m=0 or m=11
