HELP NOW PLEASE is say for each pair of angle in parts A thought D estimate the measure of each angle.
Mice21 [21]

Answer: A: V is an acute angle, so it is less than 90 degrees. I would say it's around 45 degrees.

B: K is also an acute angle, but it is fairly close to being 90 degrees, so I'd say around 80 degrees.

C:  Q is an obtuse angle, so it is over 90 degrees but less than 180 degrees. I would say it's around 110 degrees.

D: Y is an obtuse angle. It is very close to 180 degrees. I would say it's around 160 degrees.

A woman bought 210 oranges for $6.50. She sold all of them at 3 for 20cents. How much profit did she make?
Dafna11 [192]

Divide total bought by 3 and multiply by 20cents:

210/3 = 70

70 x 0.20 = $14.00

Subtract the amount they paid by the amount they made:

14.00 - 6.50 = $7.50

The profit made was: $7.50

75 is 128% of what number
Oksana_A [137]

\bold \pink{let \: the \: number \: be \: x}

\mathsf{128\% \times x = 75}

\\  \\  \frac{128}{100}  \times x = 75 \\  \\ x =  \frac{75}{1}  \times  \frac{100}{128}   \\ \\ x =  \frac{7500}{128}

\boxed{x = 58.59375}

75 is 128% of 58.59375

When three pipes fill a pool, they can finish in 12 hours. Two of the pipes can finish in 18 hours if they are working together.
ladessa [460]
3 pipes take 12 hours
⇒ In 1 hour, the 3 pipes can fill 1/12 of the pool

2 of the pipes take 18 hours
⇒ in 1 hour, the 2 pipes can fill 1/18 of the pool

In 1 hour, the third pipe alone can fill :

\dfrac{1}{12} - \dfrac{1}{18} = \dfrac{3}{36} - \dfrac{2}{36} = \dfrac{1}{36} \text { of the pool}

Time needed :

1 \div \dfrac{1}{36} = 1 \times 36 = 36 \text { hours}

----------------------------------------------------------------------------------------
Answer: It will take 36 hours for the third pipe to fill the pool.
