The nth term of a geometric progression is calculated by:
= ar^n-1
1). -3,-6,-12,-24 find a10
a = first term = -3
r = common ratio = -6/-3 = 2
n = 10
Using the formula
a10 = ar^n-1
a10 = -3 × 2^10-1
a10 = -3 × 2^9
a10 = -3 × 512
a10 = -1536
2). -2,6,-18,54 find a12
a = first term = -2
r = common ratio = 6/-2 = -3
n = 12
Using the formula
ar^n-1
a12 = -2 × -3^12-1
a12 = -2 × -3^11
a12 = -2 × -177147
a12 = 354294

Ignacio shares 2.1 liters of water equally into 7 containers. How many milliliters are in each container?
Answer: 300 ml
Step-by-step explanation:
First and foremost, we should note that:
1000 milliliters = 1 liter
Therefore, 2.1 liters = 2.1 × 1000 = 2100 millimeters.
Therefore, since the liters of water is divided into 7 containers, the vlaue in each container will be:
= 2100 millimeters / 7
= 300 millimeters

Eber can mow 4 lawns in one hour. The equation l = 4h can be used to determine the number of lawns, 1. Eber can
mow in h hours. Create a graph to represent the number of lawns Eber can mow in 0 to 5 hours. Click on the
coordinate plane to place the points in the correct locations.
Answer:
See attachment for plot
Step-by-step explanation:
Given
[tex]l = 4h[/tex]
Required
Represent the scenario on a graph
When h = 0
[tex]l = 4h= 4 * 0 = 0[/tex]
When h = 1
[tex]l = 4 * 1 = 4[/tex]
When h = 2
[tex]l = 4 * 2 = 8[/tex]
When h = 3
[tex]l = 4 * 3 = 12[/tex]
When h = 4
[tex]l = 4 * 4 = 16[/tex]
When h = 5
[tex]l = 4 * 5 = 20[/tex]
So, we have:
[tex](h,l) = (0,0)[/tex]
[tex](h,l) = (1,4)[/tex]
[tex](h,l) = (2,8)[/tex]
[tex](h,l) = (3,12)[/tex]
[tex](h,l)= (4,16)[/tex]
[tex](h,l)= (5,20)[/tex]

I need somebody to explain why the surface area of the cylinder in the image is
351.86 square inches. Yes, i know the answer but still clueless how to solve for that. (There was a test and I got the answer wrong then it revealed the right answer)
Will mark brainliest if someone truly helps me.
Answer:
Formula for to find out the surface area of a cylinder = 2πrh+2πr^2
As the radius of the cylinder (4/2) cm = 2cm
Then the surface area of the cylinder
= 2πrh + 2πr^2
=( 2×22/7×2×6 + 2×22/7 × 2^2) cm^2
= (528/7 + 176/7) cm^2
= 704/7 cm^2
=100.571428571 cm^2
=15.58860260571021 in^2 (ans)

Paying credit card and loan payments late: Late payments negatively impact your credit score and show a lack of responsibility in managing credit.
Going above your credit limit: Maxing out your credit cards or going above the credit limit can harm your credit score as it indicates a higher risk of defaulting on your debts.

Answer:
[tex]P(Work | Senior) = 0.14[/tex]
Step-by-step explanation:
Given
The attached table
Required
[tex]P(Work | Senior)[/tex]
This is calculated using:
[tex]P(Work | Senior) = \frac{P(Work \ n\ Senior)}{P(Senior)}[/tex]

Tammy has scored 82, 78, and 93 on her previous three tests. What score does she need on her next test so that her average (mean) is 81?
Answer:
She needs a grade of 71 on her next text.
Step-by-step explanation:
Mean of a data-set:
The mean of a data-set is the sum of all values in the data-set divided by the number of values.
Tammy has scored 82, 78, and 93 on her previous three tests.
Thus, her grades are 82, 78, 93 and x, in which x is her grade in the fourth test.
There are 4 tests.
What score does she need on her next test so that her average (mean) is 81?
We have to find x when the mean is 81. So
[tex]\frac{82 + 78 + 93 + x}{4} = 81[/tex]
[tex]253 + x = 324[/tex]
[tex]x = 324 - 253[/tex]
[tex]x = 71[/tex]
She needs a grade of 71 on her next text.

Mark is going to purchase a $9,000 motorcycleHis bank will finance his purchase through an add-on interest loan. They will charge Mark 7% interest over 5 years
How much in interest ?
Answer:
The interest to be charged is $ 3,150.
Step-by-step explanation:
Since Mark is going to purchase a $ 9,000 motorcycle, and his bank will finance his purchase through an add-on interest loan, and they will charge Mark 7% interest over 5 years, to determine how much in interest will be charged, the following calculation has to be done:
9000 x 0.07 x 5 = X
630 x 5 = X
3150 = X
Therefore, the interest to be charged is $ 3,150.
