Please help me with this..

Mathematics
1 answer:
REY [17]4 years ago
4 0

Answer:

y = 8

Step-by-step explanation:

Since the 2 triangles are similar then the ratio of corresponding sides are equal, that is the sides 15 and 10 and y + 4 and y, thus

\frac{15}{10} = \frac{y+4}{y} ( cross- multiply )

10(y + 4) = 15y ← distribute left side

10y + 40 = 15y ( subtract 10y from both sides )

40 = 5y ( divide both sides by 5 )

8 = y

Usimov [2.4K]

Answer:

75+ 0.55x = total amount

75 + (0.55 X 60) = $108

Step-by-step explanation:

x is a variable and represents the number of miles you drive, since you drive 60 miles you should figure out how much is 60 miles then add the flat fee of 75

The center is (2,5) and the radius is 9
kiruha [24]

Answer:

 (x-2)2+(y-5)2=92

or

(x-2)2+(y-5)2=81

Step-by-step explanation: Center:(2,5)

The center of a circle is a point from which all points on a circle are the same distance.

Radius:9

The radius of a circle is the length of a line segment from its center to its perimeter.

The radius is typically denoted as "r" or "R".

Diameter:18

The diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle.

Circumference or (or Permieter) = 2*π*R = 2*3.14*9 = 56.5486677646163

The circumference of a circle is the distance around it.

Area:254.469004940773

Area of a Circle is the amount of space occupied by the circle.The area of a circle is p times the radius squared, which is written: A = π*R2.

The standard form for the equation oif a circle is

(x-a)2+(y-b)2=r2

And in our particular case:

(x-2)2+(y-5)2=92

(x-2)2+(y-5)2=81

The general form for the equation of a circle is

x2 + y2 + Ax + By + c = 0

We can get the general form by expanding the equation of the standard form

(x-a)2+(y-b)2=r2

(x-2)2+(y-5)2=92

(x-2)2+(y-5)2=81

x2-4x+4+y2-10y+25=81

x2+y2-4x-10y-52=0
