Answer:
how many rubys are there
Step-by-step explanation:
<em>(If one square on the graph = one centimeter)</em>
<u>b = 10cm</u>
<u>b = 10cmh = 10cm</u>
Area:




Examples of rational numbers are: -2 = -2/1, -5 = -5/1, -14 = -14/1, 1/2, 2/3, 5/8, 3/4, 17/5, . 6 = 6/10 = 3/5, . 25 = 1/4, . 33 = 33/100, 2¾ = 11/4, 3⅓ = 10/3, .
Answer:
8.3 cm
Step-by-step explanation:
The product of lengths to the near and far point of intersection with the circle is the same in all cases:
(7 cm)(7 cm) = (y)(11 cm +y) = (4 cm)(4 cm +x)
Since we're only interested in x, we can divide by 4 and subtract 4:
49 cm² = (4 cm)(4 cm +x)
(49/4) cm = 4 cm +x . . . . . . divide by 4 cm
8.25 cm = x . . . . . . . . . . . . . subtract 4 cm
To the nearest tenth, x = 8.3 cm.
_____
For a tangent segment, the two points of intersection with the circle are the same point, so the product of lengths is the square of the length.
___
The angles depend on the size of the circle, which is not given.
Answer: 150 students walk to school
Step-by-step explanation: 75%=0.75
200 multiplied by 0.75
200×0.75=150 students
Or
75%=3/4
3/4 of the children walk to school
3/4×200=3/4×200/1=150
