Answer:
7.40
Step-by-step explanation:
7.38, we go to the tenths place and the number after then tenths place five or more u raise the score since its more u change hte score of the 3 to 4 and put a zero in the hundredths place
The answer is x=15 hope this is right
Answer:
Step-by-step explanation:
Given
M = 27 when Y = 16 and X = 9
Required
Find Y when M = 7 and X = 2
We start by getting the algebraic representation of the given statement
Convert the variation to an equation; we have
<em>Where K is the constant of variation;</em>
When M = 27; Y = 16; X = 9, the expression becomes
This gives
Make K the subject of formula
Solving for Y when M = 7 and X = 2
Recall that
Substitute values for K, M and X
Take square of both sides
Make Y the subject of formula
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.
