Answer:

x = 6.5

Step-by-step explanation:

By property of intersecting secants outside of circle.

6(6 + x) = 5(5 + 10) \\  36 + 6x = 5 \times 15 \\ 6x = 75 - 36 \\ 6x = 39 \\ x =  \frac{39}{6}  \\ x =  \frac{13}{2}  \\ x = 6.5

The inside wheels of a car traveling on a circular path are rotating half as fast as the outside wheels. The front two wheels ar
barxatty [35]

Answer:

  about 37.7 feet

Step-by-step explanation:

If the outside wheels are turning twice as fast, they go twice the distance in the same time. The distance they travel is proportional to the radius of the circle, so the outside circle must have twice the radius of the inside circle.

Adding 6 ft to the radius of the inside circle doubles the radius, so the inside circle's radius must be 6 feet. Then the circumference of the inside circle is ...

  C = 2πr = 2π(6 ft) = 12π ft ≈ 37.7 ft

Help plz...................................
N76 [4]

Answer:

12

Step-by-step explanation:

These are similar triangles, so the ratio of their sides is the same for each side.

AB = 8  and  BD = 10

So, the ratio is 8:10   or   4:5

Because the triangles are similar....

The ratio of AC:CE  is also  4:5

12:15 = 4:5

So, 12 is the answer!

Write the equation of the line that passes through the point P and is
gayaneshka [121]
Since the lines are parallel their slopes are equal. So, the equation is y=4x+b
Now we need to find the y-intercept, which is b.
Now, Plug in point p to find b:
3=4*(-1)+b
b=3+4=7
The equation is: y=4x+7

This year the fifth grade collected 216 fewer plastic containers than the fourth grade.How many plastic containers did the fifth
kap26 [50]

Let number of plastic containers collected by fourth grade= x

Then number of plastic containers collected by fifth grade students=x-216

OR

If number of plastic container collected by fifth grade is y

then number of plastic container collected by fourth grade=y+216

So, we can write it as follows

⇒ number of plastic containers collected by fourth grade= number of plastic containers collected by fifth grade +216
