Which of the following expressions has a value of 26.48?

gulaghasi [49]

Answer:

$26.48=\dfrac{662}{25}$

Step-by-step explanation:

The given expression is 26.48. We need to write the equivalent expression for it. There are two numbers after decimal. It means that we can divide 2648 by 100 i.e.

$26.48=\dfrac{2648}{100}$

We know that, 2648 = 662 × 4 and 100 = 25 × 4

$\dfrac{2648}{100}=\dfrac{662\times 4}{25\times 4}\\\\=\dfrac{662}{25}$

Hence, $26.48=\dfrac{662}{25}$ is the equivalent expression.

The endpoints of the longest chord on a circle are (4, 5.5) and (4, 10.5).the center of the circle is at the point , and its rad

Furkat [3]

The midpoint of the points ( 4, 5.5 ) and ( 4, 10.5 ) is the center of the circle:
C = $(\frac{4+4}{2}, \frac{5.5+10.5}{2})$
C = ( 4, 8 ), h=4, k=8
r = $\sqrt{(4-4)^{2} +(8-5.5)^{2} } = \sqrt{0+2.5^{2} }$
r = 2.5
The equation of the circle in standard form:
( x - h )² + ( y - k )² = r²
( x - 4 )² + ( y - 8 ) = 6.25
