Answer:

Cost of berries = $2.19(4.5 + 3.25)

Step-by-step explanation:

Katrina is shopping for berries that cost $2.19 per pound.

She has 4.5 pounds of raspberries so cost of raspberries = 2.19×4.5

She has 3.25 pounds of blueberries in her cart so cost of the blueberry will be = 2.19×3.25

Now Total cost of the berries = Cost of raspberries + Cost of blueberries

Cost of the berries = (2.19 × 4.5) + (2.19 × 3.25)

                               = 2.19(4.5 + 3.25)

Therefore, expression which shows the cost of the berries will be

Cost of berries = $2.19(4.5 + 3.25)

If f(x)= -3x-5 and g(x)= 4x-2 find (f+g)(x)
juin [17]

Known :

f(x) = -3x - 5

g(x) = 4x - 2

Asked :

(f+g)(x) = ...?

Answer :

(f+g)(x) = (-3x - 5) + (4x - 2)

= (-3x + 4x) + (-5 - 2)

= x + (-7)

= <u>x </u><u>-</u><u> </u><u>7</u>

So, the value of (f+g)(x) is x - 7

483.6 is what percent of 180
liraira [26]

Answer:

We assume, that the number 180 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 180, so we can write it down as 100%=180.

4. We know, that x% equals 483.6 of the output value, so we can write it down as x%=483.6.

5. Now we have two simple equations:

1) 100%=180

2) x%=483.6

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=180/483.6

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 483.6 is what percent of 180

100%/x%=180/483.6

(100/x)*x=(180/483.6)*x       - we multiply both sides of the equation by x

100=0.37220843672457*x       - we divide both sides of the equation by (0.37220843672457) to get x

100/0.37220843672457=x

268.66666666667=x

x=268.66666666667

now we have:

483.6 is 268.66666666667% of 180

Determine whether the sequence below is a geometric sequence and, if so, find a formula that describes the sequence. 1, 3, 9, 27
r-ruslan [8.4K]

a geometric sequence is a bunch of numbers where you can get from a number to the next number by multiplying the previous number by a certain number

might be confusing so here's an example

1,2,4,8,16

each term is multiplied by 2 to get next term, that number that each term is multiplied by is called the common ratio

formula for geometric sequence is

a_n=a_1(r)^{n-1}

where a_n is nth term

a_1 is first term

r is teh common ratio

n=which term


in our example

1,3, 9, 27, 81

each term is being multiplied by 3 so it is a geometric sequence and thus r=3

also first term is 1 so a_1=1

so the formula is a_n=1(3)^{n-1} or in function notation f(n)=1(3)^{n-1}
