Find the 9th partial sum of the geometric sequence an=43n–1.
Answer:
39364.
Step-by-step explanation:
I guess its an = 4*(3)^(n-1)
r = 3, a1 = 4 and n = 9
Sum of n terms = a1 * (r^n - 1) / (r - 1)
so S9 = 4 *(3^9 - 1) / (3 - 1)
= 4 * (19683 - 1) / 2
= 78728/2
= 39364.
Each ticket to a school dance is $4. The total amount in ticket sales is $332. Write and solve an equation to find the number of students attending the dance.
Answer:
a. 4x = 332
b. 83 students
Step-by-step explanation:
Write equation:
4x = 332
Since we know that each ticket per student is $4, we can use "x" as our variable for the number of students
_________________________________________-
Solve
4x = 332
/4 /4
____________
x = 83 students

What property of a rhombus is used in this proof of showing that a triangle is an equilateral triangle?
Answer:
Step-by-step explanation:
The property of rhombus that can be used to proof that a triangle is an equilateral triangle is that when it is split into two equal parts, an equilateral triangle is formed.
What is a rhombus?A rhombus is defined as a quadrilateral that has four equal straight sides with opposite sides parallel and equal opposite angles.
A rhombus with two 60 degree angles and two 120 degree angles can be split by one of its diagonals (the one that bisects the 120 degree angles) into two congruent, equilateral triangles.
Therefore, the property of rhombus that can be used to proof that a triangle is an equilateral triangle is that when it is split into two equal parts, an equilateral triangle is formed.

if a1 = 5 and an = an-1 +2 then find the value of a4
Answer:
Step-by-step explanation:
an = (an-1)2 + 5. a1 = 4. Then: a1 = 4. a2 = (4)2 + 5 = 16 + 5 = 21. a3 = (21)2 + 5 = 441 + 5 = 446. a4 = (446)2 + 5 = 198916
Yummy Cookies just opened a brand new cookie bakery, and sales are increasing every month!
In January, the baker made 10 chocolate chip cookies. In February, the baker doubled the January order, took 6 cookies home to his family, and sold the rest. If the baker continues to double the full amount and then brings 6 cookies home to his family, how many cookies will the baker sell in March and April?
Will mark Brainliest to the first answer!
Answer:
In March the baker will sell 34 chocolate chip cookies. In April he will sell 74 cookies.
Step-by-step explanation:
So first, we end up doubling the original amount of cookies from January for February which gets us 20 cookies, he takes 6 homes leaving us with 14. He continues to double the FULL amount so he doubles 20 for March which gets us 40, then we again take 6 away leaving us with 34. We do the same thing for April. Double 40 getting 80, take away 6 you get 74. Done.

In 1990 an egg cost 2c less than in 1991. In 1992 an egg cost 4c more than in 1991. The cost of 11 eggs in 1990 was the same as the cost of 8 eggs in 1992. Find the cost of an egg in 1991.
Answer:
18
Step-by-step explanation:
given that the eggs cost 16ct in 1990 and 22ct in 1992 you can calculate
16ct+2ct=18ct and 22ct-4ct=18ct

find the unknown measures. round lengths to the nearest hundredth and angle measures to the nearest degree.
Answer:
Angle I = 44
Measure GH=7.64
Measure GI=7.91
Step-by-step explanation:
Angle I:Since we know that m∠H = 46 and m∠G=90, we can find measure angle I by subtracting from 180.
[tex]180=46+90+x\\44=x[/tex]
Measure GH:Since we are given that m∠H = 46, and the triangle is right, we can use trigonometric functions to find the two sides.
First is GH, since it's adjacent to the angle, we will use cosine.
[tex]cos(x)=\frac{adjacent}{hypotenuse} \\cos(46)=\frac{adjacent}{11}\\ 11*cos(46)=adjacent\\7.64=adjacent[/tex]
Measure GI:The same idea as previous, only instead we will use sine since we need to find the opposite.
[tex]sin(x) = \frac{opposite}{hypotenuse}\\ sin(46)=\frac{opposite}{11}\\ 11*sin(46)=opposite\\7.91 = opposite[/tex]
the snake slithered 2.25 m before resting on a rock. Then the snake slithered twice as far as it did before, to catch a rat. When the snake headed home he slithered another 90 cm. What was the total distance the snake slithered?
Answer:
Step-by-step explanation:
2.25m + 2(2.25m) + 90 cm =
2.25m + 4.50m + 90 cm
6.75m + 90 cm
1 cm = 0.01m...so 90 cm = 90 * 0.01 = 0.9m
6.75m + 0.9m = 7.65m <===
2.25m + 2(2.25m) + 90 cm =
2.25m + 4.50m + 90 cm
6.75m + 90 cm
1 cm = 0.01m...so 90 cm = 90 * 0.01 = 0.9m
6.75m + 0.9m = 7.65m
OR../=-
1m = 100 cm....so 7.65m = 7.65 * 100 = 765 cm

PLEASE HELP !!!!!!??
Answer:
( 1, 35 )
Step-by-step explanation:
y=mx+c
c= y-intercept ( where the graph line crosses the cross line)
c=0
mx = gradient ( rise/run, up/across )
mx = 175/5 ( you could have picked any point in the graph )
mx = 35
the m is useless now so we discard it
y= 35x+0
if x = 1
then y = 35(1)+0
y= 35
at the coordinate x=1 y is 35
