Answer:

CD= 34

Step-by-step explanation:

As CD is the diameter the circle divides to half and point E is on the circle ∴∠CED =90° (angle of a semi circle)

as CD is the diameter it would be the lengthiest of all ∴ CD is hypotenuse

so $CD =\sqrt{16^{2} + \sqrt{30^{2} } } }$

= CD= $\sqrt{256+900}$

=CD= $\sqrt{1156}$

∴CD=34

Courtney had $55 to spend at the fair. She paid $22.50 for rides and $14.25 for lunch and snacks. Courtney says she has $18.25 l

IrinaVladis [17]

She has $55. She spent $22.50 on rides so now she has $32.50 . Then she spends $14.25 on lunch and snack so now she has $18.25.

A. would be wrong because Courtney IS correct, she has $18.25 left.

C. is also wrong because, again, Courtney IS correct.

So the only option left is B and it explains why Courtney is correct.

Option B is the correct answer.

Hope this helps.

Estimate the sum 7 8/9 + 3.1

Yanka [14]

Answer:

$\large\boxed{7\dfrac{8}{9}+3.1=10\dfrac{89}{90}}$

Step-by-step explanation:

$\text{Convert the decimal to the fraction:}\\\\3.1=\dfrac{31}{10}=3\dfrac{1}{10}\\\\7\dfrac{8}{9}+3.1=7\dfrac{8}{9}+3\dfrac{1}{10}\\\\\text{The common denominator is 90.}\\90=9\cdot10\\\\7\dfrac{8}{9}=7\dfrac{8\cdot10}{9\cdot10}=7\dfrac{80}{90}\\\\3\dfrac{1}{10}=3\dfrac{1\cdot9}{10\cdot9}=3\dfrac{9}{90}\\\\\\7\dfrac{8}{9}+3.1=7\dfrac{80}{90}+3\dfrac{9}{90}=(7+3)+\dfrac{80+9}{90}=10\dfrac{89}{90}$
