Good morning ☕️

Answer:

S=7((-\frac{2}{5})^{n-1} - 1)

Step-by-step explanation:

Consider

(Vn) the geometric Sequence

S the sum

q the common ratio

V1 the first term

S=V_{1}\frac{1-q^{n-1} }{1-q}

q=\frac{2}{-5}=-\frac{2}{5} \\ \\V_1=-5

then

S=(-5)\frac{1-(-\frac{2}{5}) ^{n-1} }{1-(-\frac{2}{5} )}

then (after a bit of calculations you’ll find)

S=7((-\frac{2}{5})^{n-1} - 1)

Carol is ordering t-shirts for her club and there are two different patterns to choose from. The first shirt is green and blue s
noname [10]

Answer:

14 Striped and 10 Flowered

Step-by-step explanation:

This can best be determined using a set of linear equations that are solved simultaneously.

This pair of linear equations may be solved simultaneously by using the elimination method. This will involve ensuring that the coefficient of one of the unknown variables is the same in both equations. It may be solved by substitution in that one of the variable is made the subject of the equation and the result is substituted into the second equation

Given that the green and blue striped shirt is $15 and the white with purple flowers is $13. She needs to order 24 shirts and has a total of $340 to spend, let the number of striped shirts be g and that of flowered be h then,

g + h = 24 and

15g + 13h = 340

g = 24 - h

15(24 - h) + 13h = 340

360 - 15h + 13h = 340

2h = 20

h = 10

g = 24 - h

g = 24 - 10

= 14

Which of the following is a proportion? <br><br> A. 4/6 = 6/9<br><br> B. 5/6 = 10/18
worty [1.4K]
Hey there mate!

Your correct answer would be \left[\begin{array}{ccc}\boxed{\boxed{ 4/6 = 6/9}}\end{array}\right] This would be because 4/6 is almost 1 as a whole, and also, 6/9 is almost 1, as a whole, so this would totally make sense for this to be a proportional.

Hope this helps you budd!

1.14 per 100 or 1.14:100 or \frac{1.14}{100}

\frac{1.14}{100} =  \frac{n}{2000}

I will multiply the numerator by 20 because multiplying by 20 is how 100 became 2000
