Answer:

60 buns

Step-by-step explanation:

Assuming that the 5 people eat 20 steamed buns between them and not each, that is an average of 4 buns per person. this means that they eat one bun every 50 seconds. therefore, in 5 minutes one person can eat a total of 6 buns, meaning 10 people can eat 60.

A street lamp casts a shadow 31.5 feet long, while an 8 foot-tall street sign casts a shadow of 14 feet long. What is the length

sergeinik [125]

Answer:

The answer to your question is the height of the lamp is 18.2 ft

Step-by-step explanation:

Data

Street lamp shadow = 31.5 ft

Street sign height = 8 ft

Street sign shadow = 14 ft

Street lamp height = x

Process

1.- To find the height of the lamp use proportions. In this kind of problem, we do not look for the length, but the shadow.

Street lamp height/street lamp shadow = street sign height/street sign

shadow

Substitution

x / 31.5 = 8 / 14

Solve for x

x = (31.5)(8) / 14

Simplification

x = 254.4 / 14

Result

x = 18.2 ft

After years of maintaining a steady population of 32,000, the population of a town begins to grow exponentially. After 1 year an

galben [10]

Answer:

$y=32000(1+0.08)^x$

Step-by-step explanation:

Exponential growth function is $y=a(1+r)^x$

Where 'a' is the initial population

r is the rate of growth and x is the time period in years

a steady population of 32,000. So initial population is 32,000

an increase of 8% per year. the rate of increase is 8% that is 0.08

a= 32000 and r= 0.08

Plug in all the values in the general equation

$y=a(1+r)^x$

$y=32000(1+0.08)^x$

$y=32000(1+0.08)^x$

Prescription for Marilyn Jones

Vanyuwa [196]

Answer:

Step-by-step explanation:

We can ignore Piroxicam, because it comes in capsules.

1. Number of Glucotrol tablets

Marilyn takes one tablet per day.

$\text{No. of tablets} = \text{8 da} \times \dfrac{\text{1 tab}}{\text{1 da}} = \text{8 tab}$

2. Number of Isoniazid tablets

Marilyn takes three tablets per day.

$\text{No. tablets} = \text{8 da} \times \dfrac{\text{3 tab}}{\text{1 da}} =\text{24 tab}$

3. Total tablets

Total tablets = 8 tab + 24 tab = 32 tab

Marilyn takes 32 tablets in eight days.

Max found a pair of jeans on sale for 40 percent off. He used a coupon for an additional 20 percent off. If the original price o

Fittoniya [83]

First, you need to take 40% off of the original price ($68) to find the discount. to do this, multiply 68 by 0.4 (.4 is 40% in decimal form). You should get $27. 20. Next, you subtract this from 68- keep in mind that we found the discount, not the actual price. 68- 27.20= 40.8. Now, we multiply this by 20%, or 0.2- you should get 8.16. Subtract that from 40.8 to get <u>$32.64</u>.
