Answer:

5 hours

Step-by-step explanation:

Make a proportion

She served 48 people in 3 hours, and served 80 people in x hours

48/3=80/x

Cross multiply

48*x=80*3

48x=240

Divide both sides by 48 to isolate x

x=5

So, it will take 5 hours to serve 80 people

The amount of money raised at a school fundraiser is directly proportional to the number of people who attend. Last year the amo

sweet-ann [11.9K]

Answer:

Amount of money raised for 875 people=A=$21,875

Step-by-step explanation:

This can be expression in the equation, A=k.N;

Where;

A=Amount of money raised=$2500

k=Constant of proportionality(Amount of money per attendee)

N=Number of attendees=100

Replacing in the expression;

Amount of money raised=K×Number of people who attend

2500=K×100

K=(2500/100)=25

Amount of money per attendee=K=$25 per attendee

How much money was raised for 875 people?

Using the expression, A=k.N

where;

Number of people (N)=875

k=25

Replacing;

A=(25×875)=$21,875

Amount of money raised for 875 people=A=$21,875

Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

y = 4 - 5x or y = - 5x + 4 ← is in slope- intercept form

with m = - 5 and b = 4

Natasha spent 1\dfrac121 2 1 1, start fraction, 1, divided by, 2, end fraction hours on the beach. She fell asleep for \dfrac3

Oksana_A [137]

Answer:

1 and 1/8 hours or

Step-by-step explanation:

Natasha spent one and a half hours on the beach, which can be rewritten as 3/2 hours. Out of that time, she spent 3/4 sleeping. The total time she spent sleeping on the beach is determined by the product of the amount of time she spent on the beach by the fraction of that time she spent asleep:

$T=\frac{3}{2} * \frac{3}{4}\\T=\frac{9}{8} \\T=1 + \frac{1}{8}$

Natasha was asleep on the beach for 1 and 1/8 hours or 1 hour 7 minutes and 30 seconds.
