Solve this and explain it for me

Mathematics
1 answer:
Citrus2011 [14]3 years ago
4 0

Answer:

1 year.

Step-by-step explanation:

set up an expression for each in terms of x, where x is the number of years gone by.

for type a, it starts at 5 feet, and grows 9 inches per year.

so 5 + 9x = total height after x years

for type b, it starts at 8 feet and grows 6 inches per year, so 8 + 6x = total height after x years.

we want to find after how many years will they have the same so set them equal to each other and solve for x.

9x + 5 = 6x + 8

3x = 3

x = 1

inysia [295]
I haven’t done this in a while, but I believe that the “of” in the equation means multiply so you do 3/4 x 1/3 to get 3/12 (simplified to 1/4)!!

A population of beetles are growing according to a linear growth model. The initial population (week 0) is P0=9
Varvara68 [4.7K]

Answer:

P(n)=5n+9

Step-by-step explanation:

The initial population (week 0), P_0=9

Population after 5 weeks, P_5=44

Since the population is growing according to a linear growth model.

A linear model is of the form: y=mx+b where m is the slope and b is the y-intercept.

First, we determine the population growth per week which is our slope.

m =\dfrac{44-9}{5-0} =\dfrac{35}{5}\\$Growth per week, m = 5 beetles per week

We then have:

y=5n+b

When Number of weeks, n=0, P_0=y=9

Therefore: 9=5(0)+b

b=9

Therefore, our population after n weeks:

P(n)=5n+9

fiasKO [112]

The cost per friend is $6.84.

<h3>What is the cost per friend?</h3>

The first step is to determine the total cost of the vegetables the two friends bought.

Total cost of the vegetables = ( 1 x $2.82) + 4.19 X 2 + (1.24 x 2) = $13.60

In order to determine the cost per friend, divide the total cost of the vegetables by the number of friends that purchased the items.

$13.6 / 2 = $6.84
