If the ratio is 50g to 300 ml how many ml would be needed for 83g

Natali [406]

Answer:

498 ml would be needed for 83g.

Step-by-step explanation:

♧We can solve using proportion.

$\frac{50 \: g}{300 \: ml} = \frac{83 \: g}{x} \\ \\ \frac{24900}{50} = \frac{50x}{50} \\ \\ 498 = x$

Right triangle XYZ is shown. Y (2,6) (1, 2) 6 х 7 Z Rounded to the nearest hundredth of a unit, what is the length of the hypote

Dmitriy789 [7]

Answer:

8.12

Step-by-step explanation:

We obtain the distance between x and y

d = sqrt[(x2 - x1)² + (y2 - y1)²]

d = sqrt[(1 - 2)² + (2 - 6)²]

d = sqrt[1 + 16)

d = sqrt(17)

d² = 17

From Pythagoras rule;

Hypotenus = sqrt(Adjacent² + opposite²)

Hence,

Hypotenus = sqrt(17 + 7²)

Hypotenus = sqrt(17+ 49)

Hypotenus = sqrt(66)

Hypotenus = 8.124

Hypotenus = 8.12

Can somebody please help me?

Lisa did not completely solve the equation. When she was left with x^2 = 9, she should have taken the square root of x and 9 to isolate the variable. She would have gotten x = 3 or x = -3.
