The polygons are similar. Find x and y. The images are not drawn to scale.
Alja [10]
The correct answer to this question is letter "D. x = 21, y = 14."
18 : 12
27 : x - 3
24 : y + 2

18 / 12 = 27 / x - 3
3  / 2 = 27 / x - 3
54 = 3x - 9
3x = 54 + 9
3x = 63
x = 21

18 / 12 = 24 / y + 2
3  / 2 = 24 / y + 2
48 = 3y + 6
3y = 48 - 6
3y = 42
y = 14

a baker used 4 cups of flour to make 5 batches of brownies.he used - of a cup of flour to make 1 batch
ELEN [110]

Answer:

4/5th of a cup of flour

Step-by-step explanation:

4 cups flour to 5 batches brownies = x cups flour to 1 batch brownies

4 / 5 = x / 1......cross multiply because this is a proportion

(5)(x) = (4)(1)

5x = 4.....divide both sides by 5

x = 4/5

so he used 4/5 of a cup of flour to make 1 batch of brownies <==

Write and equation ( and maybe solve) please!
mihalych1998 [28]
49.75 - 8 = 41.75.  41.75 / 1.369 = 30.4967129.  Let's round it to 2 decimal points, which is 30.5.  The maximum number of litres of gasoline that Terri can purchase is 30.5.  If m= money, c= price of car wash and g= price of gasoline per litre, the equation is (m - c) / g.

The formula for the circumference of a circle C equals two pi R where are is the radius and see is the circumference equation so
Leto [7]

Answer:

8

Step-by-step explanation:

The question is basically <em>"Find the radius of the circle that has a circumference of 16π"</em>

<em></em>

The formula for circumference of a circle is given as  C=2\pi r

Where

C is the circumference

r is the radius

Plugging in <em>16π</em><em> into C</em> and solving for r gives us the radius. Shown below:

C=2\pi r\\16\pi = 2\pi r\\r=\frac{16\pi}{2\pi}\\r=8

the radius is 8
