A cylinder has a volume of 175 pie cubic units and a height of seven units what's the diameter
Debora [2.8K]
Πr²h=175
πr²*7=175
Divide both sides by 7
πr²=25
Divide both sides by π (3.14)
r²=7.96
Square root of 7.96=2.82
r=2.82
Diameter is 2r. 2.82*2

13x-11 +18x15+ 4x+1=180°
BARSIC [14]

Answer:

x = - 80/17, or x = - 4 \frac{12}{17}

Step-by-step explanation:

13x-11 +18×15+ 4x+1=180°

<=> (13x + 4x) + (18×15+ 1 - 11)=180°

<=> 17x + 260 =180

<=> 17x = 180 - 260

<=> 17x = - 80

<=> x = - 80/17

<=> x = - 4 \frac{12}{17}

What is the equation of the line x–3y=18in slope-intercept form?
masha68 [24]

Answer:

the answer would be done like this

Step-by-step explanation:

you have to get y by itself so you would need to move the x to the right of the equal sign

once you move anything to the opposite side it switches, so positive becomes negative vice versa

-3y=-x+18

you need to make sure you have positive 1 y so you would divide y by -3 to make it 1

everything else is multiplied by -3 as well

so the answer would be y=⅓x-6
