$50(1+0.20) = <u>$60</u>

2. Fred buys a video game disk for $4. There was a discount of 20%. What is the sales price?

$4(1-0.2) = <u>$3.20</u>

3. A painting is on sale at 50% off. The sale price is $320. What was the original price?

Ruben put an empty cup underneath a leaking faucet. After 1 1/2 hours, Ruben had collected 1/4 cup of water. What is the rate, i

worty [1.4K]

Answer:

The rate is $\frac{1}{6}$ cups per hour

Step-by-step explanation:

It took the faucet 1 1/2 hours, i.e 1.5 or 3/2 hours to fill 1/4 cup by leaking

We need to find the rate in terms of cups that can be filled by water in 1 hour.

Using unitary method:

If it takes $\frac{3}{2}$ h for $\frac{1}{4}$ cup;

then it will take 1 h for how many cups?

$= \frac{1 \times \frac{1}{4} }{\frac{3}{2} }$

$= \frac{2}{4 \times 3}$

$= \frac{2}{12}$

$= \frac{1}{6}$ cups

Therefore, the rate is $\frac{1}{6}$ cups per hour

Trigonometry (ASAP) (Urgent)

Olin [163]

Answer:

h = 1.403733341286

Step-by-step explanation:

17.

the triangle of sides ‘l’ and ‘l-h’ is a right angled triangle.

Then

$\cos \theta =\frac{l-h}{l}$

Then

$l\cos \theta =l-h$

Then

$h=l-l\cos \theta$

18.

For l = 6 and θ = 40 :

$h=l-l\cos \theta$

= 6-6cos(40)

= 1.403733341286
