Quantity of rice vinegar= one and half parts of total

Quantity of cide vinegar = 5 parts of total

ratio of rice vinegar : cide vinegar = 1.5 :5

total quantity = 17 ounces

$quantity of rice vinegar = \frac{1.5}{6.5} * 17$

Quantity of rice vinegar = 3.92 ounces

1.5:4=9:(2y+5)<br><br> Solve for y

pashok25 [27]

Answer:

y = 9.5

Step-by-step explanation:

Express the ratios in fractional form, that is

$\frac{1.5}{4}$ = $\frac{9}{2y+5}$ ( cross- multiply )

1.5(2y + 5) = 36 ( divide both sides by 1.5 )

2y + 5 = 24 ( subtract 5 from both sides )

2y = 19 ( divide both sides by 2 )

y = $\frac{19}{2}$ = 9.5

What is the slope of the line that passes through (-4, 5) and (2, -3)?

ella [17]

Answer:

$m=\frac{-4}{3}$

$y=\frac{-4}{3}x -\frac{1}{3}$

Step-by-step explanation:

Use the Slope formula...

$\frac{-3-5}{2-(-4)}$

$\frac{-8}{6} = \frac{-4}{3}\\\frac{-4}{3} = m$

Plug the slope into the Point-Slope formula...

$y -(5) = \frac{-4}{3}(x-(-4)) \\y+5=\frac{-4}{3}x +\frac{-16}{3}\\y=\frac{-4}{3}x +\frac{-1}{3}$

Answer:

You have the formula wrong.

The volume of a cylinder = PI * radius^2 * height

To find the height, the formula is:

height = volume / (PI*radius^2)

I'm assuming the radius = .6 meters so

height = 720 / (3.14159265 * .6^2)

height = 720 / 1.130973354

height = 636.61977 meters

PLEASE HURRY!!! AB = 20 cm, m∠A = 30° , and $m∠C = 45° . Express the number of centimeters in the length of BC in simplest radic

MrRissso [65]

Using the Sine Rule:-

20 /sin 45 = BC / sin 30

BC = 20 sin 30 / sin45

= 20 * 1/2 / 1 / sqrt2
= 20 * 1/2 * sqrt2
= 10 sqrt2 answer
