Quadrilaterals ABCD and PQRS shown below are two similar figures.Find the values of x and y.​

Mathematics
1 answer:
nadezda [96]3 years ago
3 0

Answer:

x = 12, y = 16

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are equal, that is

\frac{AD}{PS} = \frac{DC}{SR} , substitute values

\frac{20}{2x+6} = \frac{18}{27} ( cross- multiply )

18(2x + 6) = 540 ( divide both sides by 18 )

2x + 6 = 30 ( subtract 6 from both sides )

2x = 24 ( divide both sides by 2 )

x = 12

-------------------------------------------

and

\frac{AB}{PQ} = \frac{DC}{SR} , substitute values

\frac{y}{24} = \frac{18}{27} ( cross- multiply )

27y = 432 ( divide both sides by 27 )

y = 16

An ice cream shop sold 48 vanilla milkshakes in a day, which was 40% of the total number of milkshakes sold that day. What was t
german

Answer:

They sold 120 milkshakes that day

Step-by-step explanation:

We can set up a proportion

\frac{48}{m} =\frac{2}{5}

48*5=2m\\ 2m = 240\\m  = 120\\

Note: If you have some value, v, and it is \frac{x}{100} of the total amount, you can find the value by doing the equation \frac{v}{x}*100
