Find the term to term rules for the following sequences:
b)
2, 6, 18, 54, 162
Answer: Please see explanation column for answer
Step-by-step explanation:
According to sequence 2, 6, 18, 54, 162
--we can see that it is a geometric sequence since to go from one term to the next requires us to multiply by 3 which is called the common ratio which is gotten by dividing the next by the previous.
ie term 2/ term 1= 6/2 = 3
term 3/ term 2= 18/6= 3
term 4/ term 3= 54/28= 3
term 5 / term 4= 162/54=3
term 6 will therefore be 162 x3 = 486
and term 7 = 486 x 3=1,458 and so on
Recall that nth term of GP is
Tn = ar^n-1
Where a= first term
r= common ratio
n= term
such that to easily find particular term, we plug in the values and calculate
for example the 10th term of the above sequence
Tn = ar^n-1
= 2 X 3 ^(10-1)
2 X 3^9
T10 =39,366
What are the scale factor and the center of dilation?
Answer:
Scale factor 2.5, Center of dilation is (-8,3)
Step-by-step explanation:
A dilation is a non rigid transformation. We know that a center of a transformation expect translations mean that it dont matter what change we do to the the pre image to get the new image. The center will stay where it was at all times. Looking at the figure, between the pre image and new image the only point that stays is Point K and point K' . so K is the center of the dilation and that at (-8,3).. Since the pre image is smaller than the new image we know the image scale factor is greater than 1 so the scale factor is expanding. To find the scale let look point K and L we need to find how far are they away from each other and which in this case is 4. Now let look at point K' and Point L'. There distances is 10. You can do the same for K and J. K and J distance is 2 units right and 4 units down. K' and J' distance is 5 units right and 10 units down.
Using this let set a proportion of one point from bigger figure to smaller figure. Distance in current image/ Distance in pre image. Let use K and J so it will be 10/4=2.5 so the scale factor is 2.5
Jada was using square stickers with a side length of 3/434 inch to decorate the spine of a photo album. The spine is 10 1/21012 inches long. If she laid the stickers side by side without gaps or overlaps, how many stickers did she use to cover the length of the spine?
Answer: The number of stickers she used to cover the length of the spine = 14.
Step-by-step explanation:
Given: The length of spine = [tex]10\dfrac12[/tex] inches = [tex]\dfrac{21}{2}[/tex] inches
Length of each sticker = [tex]\dfrac34[/tex] inch
If she laid the stickers side by side without gaps or overlaps, the number of stickers she use to cover the length of the spine = [tex]\text{(Length of spine)}\div (\text{Length of each sticker})[/tex]
[tex]=\dfrac{21}{2}\div\dfrac{3}{4}\\\\=\dfrac{21}{2}\times\dfrac{4}{3}\\\\=\dfrac{7\times2}{1}=14[/tex]
The number of stickers she used to cover the length of the spine = 14.

2/3a - 1/6 =1/3
a = 3/4
a = 1/4
a = 7/12
a = 1/6
Answer:
2/3a - 1/6 =1/3
2/3a=1/3+1/6
2/3a=1/2
a=1/2×3/2=3/4
:.a=3./4
What is the equation of the line graphed below ?
if the original quantity is 8 and the new quantity is 2 what is the percent decrease
Answer:
75%
Step-by-step explanation:
12.5 percent decrease per 1, multiply by 6, =75
Answer:
It’s a 75% decrease
Step-by-step explanation:
2 is 25% of 8 so since 8-2= 6 and 6/2=3 so you’d do 25 x 3 = 75 giving you 75%
Solving Linear Equations involving Distribution
Solve the linear equation:
3.4 + 2(9.7 - 4.8x) = 61.2
What are the possible steps involved in solving this
equation? Check all that apply.
Add 3.4 and 2.
Distribute 2 to 9.7 and -4.8x.
Combine 3.4 and 19.4.
Divide both sides by 22.8.
Subtract 22.8 from both sides.
Divide both sides by -9.6.
Answer:
-4
Step-by-step explanation:
3.4+2(9.7-4.8x)=61.2
2(9.7-4.8x)=61.2-3.4
2(9.7-4.8x)=57.8
9.7-4.8x=57.8/2
9.7-4.8x=28.9
4.8x=9.7-28.9
4.8x=-19.2
x=-19.2/4.8
x=-4
Answer:
B, C, E, FStep-by-step explanation:
B. Distribute 2 to 9.7 and −4.8x.
C. Combine 3.4 and 19.4.
E. Subtract 22.8 from both sides.
F. Divide both sides by −9.6.

MARK ME BRAINLIEST TYYEFMalik and Tasha each worked three days in one week at the grocery store. Each day, Malik worked 2 fewer hours than Tasha. They worked a total of 18 hours that week. Find the number of hours that Tasha worked each day.
Answer:
Step-by-step explanation:
Firstly, since they worked 18 hours over 3 days, they worked a total of 6 hours each day. Since Malik worked 2 fewer hours than Tasha, we have that Tasha worked (6+2)/2 = 4 hours each day and Malik worked 2 hours each day.

Use the figure above to solve for x
Answer:
x is equal to 7
Step-by-step explanation:
Because the two horizontal lines are parallel, we know that the angles at which they intersect the diagonal line will be identical.
We also know that on either side of the diagonal line, the sum of the angles between that and either of the horizontal lines will be 180.
In short, we know that the two values given have a sum of 180. With that we can quickly solve for x:
(x + 67) + (x + 127) = 180
2x + 194 = 180
2x = -14
x = 7

Answer:
x = 7.5
Step-by-step explanation:
This can be solved via cross multiplying.
6x = 5 × 9 | Multiply the denominators by the respective nominators.
6x = 45 | Multiply 5 × 9
x = 7.5 | Divide 45 ÷ 6 (Division Property of Equality)
Answer:
x=7.5
Step-by-step explanation:
for this you would cross-multiply to get x
6x=9(5)
6x=45
x=7.5

Answer:
No
Step-by-step explanation:
Assuming sides ABC, the values of the angles would be the following.
Angle ∠A = 94.905° = 94°
Angle ∠B = 35.535° = 35°
Angle ∠C = 49.561° = 49°
A right triangle is a triangle with a 90° angle. Therefore, the answer is no.

Answer:
b. 82m³
Step-by-step explanation:
[tex]V = \frac{1}{3}(\frac{1}{2} bh_1)h_2\\b = 8.2m\\h_1 = 4m\\h_2 = 15m\\\\V = \frac{1}{3}(\frac{1}{2}(8.2)(4))(15)\\V = 82m^{3}\\[/tex]
Answer:
B, 82 meters cubed
Step-by-step explanation:
The formula for volume of a triangular pyramid is 1/3Ah, where A = the area of the triangular base, and h = the height of the pyramid.
The area of the base here is 1/2 base x height, so:
1/2 x 8.2 x 4 = 1/2 (32.8) = 16.4 meters squared.
Plug this into the formula for the volume of the pyramid:
1/3 x 16.4 meters squares x 15 meters = 82 meters cubed
Sara receives a 9% commission on every car she sells. The car dealership paid $20,000 for a car from an auction. The next day they sold the car for 20% more than they paid. How much commission did Sara earn on the selling price of the car?
Hey there! Your answer to this problem is 2160..
Explanantion:
Since every car Sara sells, she gets 9% of the commission, this means that at the last few step, we would have to give 9% of the total cost to Sara.
If 100% is 20,000, then 50% would be 10,000. But we have to find the cost of 20%. So what we would actually be doing is multiplying 20 with 0.01. 20x0.01 is 0.2 or 0.20.
Then you add the 4,000 to the 20,000 because it states, “the next day, they sold the car 20% more than they paid. This means that you’ll have to add it. 20,000 plus 4000 would be 24,000. So 24,000 would be the cost of the car they sold.
However they didn’t wanna know the cost of the car, they wanted to know how much Sara would get. So you would have to take 9% of the cost of the cost which would be 2,160.
Final result: $2,160
Paguei 74,00 por uma bolsa e uma sandália. A bolsa foi 23,00 mais barato q a sandália. Qual o preço da sandália?
Responda:
48,5
Explicação passo a passo:
Dado que:
Custo total de bolsa e sandália = 74,00
Deixei :
Custo da sandália = x
Custo da bolsa = x - 23
Preço da sandália:
x + (x - 23) = 74
x + x - 23 = 74
2x - 23 = 74
2x = 74 + 23
2x = 97
x = 97/2
x = 48,5
Portanto, custo da sandália, x = 48,5
