What is the common ratio for this geometric sequence?

Anastasy [175]

Answer:

Step-by-step explanation:

$\text{The common ratio of a geometric sequence}\ a_n:\\\\r=\dfrac{a_{n+1}}{a_n}\\\\\text{We divide next term by the previous one.}\\\\r=\dfrac{9}{27}=\dfrac{9:9}{27:9}=\dfrac{1}{3}\\\\r=\dfrac{3}{9}=\dfrac{3:3}{9:3}=\dfrac{1}{3}\\\\r=\dfrac{1}{3}\\\vdots$

Lynette drove 248 miles in four hours at that rate how many hours will it take her to drive an additional 93 miles

tatyana61 [14]

Remark

The question becomes "How long does it take her to drive 248 + 93 = 341 miles?"

Answer

Set up a simple proportion.

248/4 = 341/x Cross multiply

248 * x = 4 * 341

248 x = 1364 Divide by 248

x = 1364/248

x = 5.5 hours

But you are only asked about the 93 miles.

Answer: The number of hours for 93 miles is 5.5 - 4 = 1.5

1 Middle School Mathematics 5 points stio49304Asked 03.20.2020 Charlotte runs a farm stand that sells bananas and raspberries. E

denis23 [38]

Answer:

The number of pounds of bananas sold are 50 and the number of pounds of raspberries sold are 37.

Step-by-step explanation:

Given:

Charlotte runs a farm stand that sells bananas and raspberries.

Each pound of bananas sells for $3.25 and each pound of raspberries sells for $1.75.

Charlotte sold 13 more pounds of bananas than pounds of raspberries and made $227.25 altogether.

Now, tot find the number of pounds of bananas sold and the number of pounds of raspberries sold.

Let the number of pounds of raspberries be $x.$

Let the number of pounds of bananas be $x+13.$

Selling price of each pound of raspberries = $1.75.

Selling price of each bananas = $3.25.

Total price of bananas and raspberries sold = $227.25.

Now, we put an equation to get the number of pounds of bananas sold and the number of pounds of raspberries sold:

$x(1.75)+x+13(3.25)=227.25\\\\1.75x+3.25x+42.25=227.25\\\\5x+42.25=227.25$

Subtracting both sides by 42.25 we get:

$5x=185$

Dividing both sides by 5 we get:

$x=37.$

The number of pounds of raspberries = 37 pounds.

Substituting the value of $x$ :

$x+13\\\\=37+13\\\\=50.$

The number of pounds of bananas = 50.

Therefore, the number of pounds of bananas sold are 50 and the number of pounds of raspberries sold are 37.

Ms. Karone orders a total of 350 black, blue, and red pens for the school.

Natalka [10]

Answer:

Last equation 350 - 170 - 120 = r

Step-by-step explanation:

So if she ordered 350, and we already know 170 + 120 for black and blue pens. So we add 170 and 120 to get 290. So we subtract 290 from 250 and get 60. So the equation is 350 - 170 - 120 = r. Brainliest please!
