Answer:

-5

Step-by-step explanation:

The common ratio is what you have to multiply one term by to get the next term.

so:

$18 \times r = -90\\-90 \times r = 450$

where r is the common ratio

We can solve these equations:

-90 / 18 = -5

450/-90 = -5

therefore the common ratio is -5

The weight of a bull clad is 388 kilograms. If it’s weight increases at a rate of 1 2/5 kilograms per day how long it will take

Alex73 [517]

Answer:

It will take 80 days for the bull calf to reach a weight of 500 kilograms.

Step-by-step explanation:

Given:

The weight of a bull calf is 388 kilograms.

Now, to find the weight of bull calf of how long it will take to reach a weight of 500 kilograms, if it’s weight increases at a rate of 1 2/5 kilograms per day.

Required weight which to be increased = 500 - 388 = 112 kilograms.

Rate of weight increase = $1\frac{2}{5}=\frac{7}{5}$

= $1.4\ kilograms.$

Thus, the time required = $\frac{required\ weight}{rate\ of\ weight}$

= $\frac{112}{1.4}$

= $80.$

The time required = 80 days.

Therefore, it will take 80 days for the bull calf to reach a weight of 500 kilograms.

What will be the cost for 8 hours of work? 10 hours of work?

andreyandreev [35.5K]

Answer:

Cost = 25 + 50h

cost for 8 hours of work = $425

cost for 10 hours of work = $525

Step-by-step explanation:

The question is as following:

A plumber charges $25 for a service call plus $50 per hour of service write an equation to represent the cost of hiring this plumber.

what will be the cost for 8 hours of work? 10 hours of work?

=======================================================

A plumber charges $25 for a service call plus $50 per hour

Cost = 25 + 50h

Where h is the number of hours of service

8 hours of work: h = 8

Substitute with h = 8 at the equation of cost

Cost = 25 + 50* 8 = $425

10 hours of work: h = 10

Substitute with h = 10 at the equation of cost

Cost = 25 + 50 * 10 = $525
