Gavin, Sarah, and Pip share £136 in a ratio of 3:2:3. How much money does each person get?
evablogger [386]

Answer:

gavin gets £51

sarah gets £34

pip gets £51

Step-by-step explanation:

3 + 2 + 3 = 8

136 ÷ 8 = 17, so 1 = 17

gavin = 3 x 17 (51)

sarah = 2 x 17 ( 34)

pip = 3x17 (51)

51+51+34= 136

PLEASE HELP NOW!<br> (-2, -4) and (-3, -3) in a linear equation
chubhunter [2.5K]

The linear equation is y = -x - 6

Step-by-step explanation:

To form a linear equation from two points lie on the line which the equation represented it

  • Find the slope of the line by using the formula m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}
  • Then use the slope-intercept form of the equation y = m x + b
  • To find the value of b substitute x and y of the equation by the coordinates of one of the two given points

∵  Points (-2 , -4) and (-3 , -3) lie on the line

∴ x_{1} = -2 and x_{2} = -3

∴ y_{1} = -4 and y_{2} = -3

- Substitute these values in the formula of the slope

∵ m=\frac{-3-(-4)}{-3-(-2)}=\frac{-3+4}{-3+2}=\frac{1}{-1}

∴ m = -1

∵ The form of the equation is y = m x + b

∵ m = -1

∴ y = (-1) x + b

∴ y = -x + b

To find b substitute x and y in the equation by the coordinates of

point (-2 , -4) OR (-3 , -3)

∵ x = -3 and y = -3

∴ -3 = -(-3) + b

∴ -3 = 3 + b

- Subtract 3 from both sides

∴ -6 = b

∴ The equation is y = -x + (-6)

∴ y = -x - 6

The linear equation is y = -x - 6

Find the volume of a right circular cone that has a height of 2.7 ft and a base with a diameter of 14.4 ft. Round your answer to
irina1246 [14]

Answer:

V≈146.57ft^3

Step-by-step explanation:

V=πr^2·h/3  since d is 14.4, we would divide it by 2 to find the radius which is 7.2

so V= π(7.2)^2· (2.7)/3

V≈146.57ft^3

It would be greatly appreciated if you gave me the brainlest
