First three terms of a sequence is shown below. Determine if the sequence is geometric. If so, state the common ratio.
30, 10, 103, ...
a.The sequence is geometric, and the common ratio is 13.
b.The sequence is geometric, and the common ratio is 3.
c.The sequence is geometric, and the common ratio is -20.
d.The sequence is not geometric.
Answer:
Step-by-step explanation:
The common ratio is a constant found by dividing any term by the previous term.
10/30=1/3
103/10=10.3
Since those fractions are not equal this is NOT a geometric sequence.

Estimate the percent using decimals.
48% of 400
Step-by-step explanation:
getcalc.com's fraction to decimal calculator to find what's an equivalent decimal for the fractional number 48/400.
50/400 0.125 12.5%
49/400 0.1225 12.25%
48/400 0.12 12%
47/400 0.1175 11.75%
Answer:
fraction to decimal calculator to find what's an equivalent decimal for the fractional number 48/400.
0.12 is a decimal and 12/100 or 12% is the percentage for 48/400.
Step-by-step explanation:
A fraction consists of two numbers and a fraction bar:
48/400
The number above the bar is the numerator: 48
The number below the bar is the denominator: 400
Divide the numerator by the denominator to get fraction's value:
Val = 48 ÷ 400
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% = p/100 = p ÷ 100.
Calculate fraction's value.
Divide the numerator by the denominator to get fraction's value:
48/400 =
48 ÷ 400 =
0.12
Note:
100/100 = 100 ÷ 100 = 100% = 1
Multiply a number by the fraction 100/100,
... and its value doesn't change.
Calculate the percent value:
0.12 =
0.12 × 100/100 =
(0.12 × 100)/100 =
12/100 =
12%;

Answer:
The range here is 85
Step-by-step explanation:
Here, we want to calculate the range of the data
Mathematically, the range is defined as the difference between the lowest value and the highest value in the dataset
From the given data points, the highest value is 189, while the lowest value is 104
So the range is the difference between the two which is;
189-104 = 85

Mohamed wants to buy a television that costs $800, including taxes. To pay for the television, he will use a payment plan that requires him to make a down payment of $200, and then pay $65 each month for 10 months. What is the percent increase from the original cost of the television to the cost of the television using the payment plan?
Answer:
6.25%
Step-by-step explanation:
I'm simply returning the favor.
If the down payment is $200, then we can subtract:
$800 - $200 = $600
Then we can find the "rent" times ten, then subtract it from the $600 left to pay.
$65*10 = $650
Now here is the hard part. We know that 600 < 650. So we need to subtract 650 from 600.
$650 - $600 = $50
Now we need to find how much more Mohamed paid than the original price.
$850 is _____% more than $800.
$850 is 106.25% more than $800.
Subtract 100% to get the difference.
6.25% is your answer.
Hope this helps. Have a nice day.
What is the area of this compound shape?

139.36
Step-by-step explanation:
first you do 8*8 because that would be the area of the square part
8*8=64
then find the area of the semicircle
first the Radis of it is 4 because 8/2=4
A=3.14R^2/2

Answer:
Caitlyn's average is roughly 11.4.
Step-by-step explanation:
You get this by dividing 46 by 4, which gets you 11.5.
You then divide 79 by 7, that equals 11.3, rounded.
The number in-between the two numbers is 11.4.

Compare Texas to Carolina. Write the answer in scientific notation. Texas= 2.5x10 to the power of 5. Carolina= 1.2x10 to the power of 3.
Answer:
Texas is 2.08333 * 10^2 times the size of Carolina.
Step-by-step explanation:
Given :
Given that:
Texas= 2.5x10^5
Carolina = 1.2x10^3
Comparing the size of Texas and Carolina
Texas / Carolina
(2.5 * 10^5) ÷ 1.2 * 10^3
(2.5/1.2) * 10^5-3
2.08333 * 10^2
Hence, Texas is 2.08333 * 10^2 times the size of Carolina.

A fountain holds 12500 7/8 gallons of water. Joe wants to calculate how many liters that is. Which proportion could he use to solve for the number of liters? (1 gal = 3.79 L)
Answer:
47378.31625 Liters
Step-by-step explanation:
A fountain holds 12500 7/8 gallons of water. Joe wants to calculate how many liters that is. Which proportion could he use to solve for the number of liters? (1 gal = 3.79 L)
From the above question,
1 gallon = 3.79 Liters
12500 7/8 gallons = x Liters
Cross Multiply
x Liters = 12500 7/8 × 3.79 Liters
x = 47378.31625 Liters
Therefore, the number of liters of water in the fountain is 47378.31625 Liters

A tv costs $215 and has a 30% increase. What is the amount of increase? Show your work
i well try to give brainlist for first to answer correctly
Answer:
The price increased by 64.5, which makes a total of 279.5
Step-by-step explanation:
215*0.30 = 64.5
215 + 64.5 = 279.5
0.30 = 30% of 100
When you multiply by 0.30 you get 30%, or with any decimals, like multiply by 0.50 to get 50% of something, etc.

Find the measure of the given angles. Show work!!
Answer:
m∠A = 45⁰
m∠B = 75⁰
Step-by-step explanation:
Given question 4;
m∠A = x + 51
m∠B = 81 + x
m∠C = 60⁰
The value of the missing angles can be determined by the finding the value of x first;
m∠A + m∠B + m∠C = 180⁰ (sum of angles in a triangle)
(x + 51) + (81 + x) + 60⁰ = 180
(x + x) + (51 + 81 + 60) = 180
2x + 192 = 180
2x = 180 - 192
2x = -12
x = -12/2
x = -6
Thus, the values of the angles are calculated as follows;
m∠A = x + 51
= -6 + 51
= 45⁰
m∠B = 81 + x
= 81 - 6
= 75⁰

Answer:
Step-by-step explanation:
ive done this before and the answer to the equation is c and also truss me on this if you want. I wouldnt
The inequality that describes the possible value of x is 2< x < 22.
What is inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. Therefore, inequality emerges from a lack of balance.
Given that ∠A = 50°
AB ≈ DE ≈ EF
BC = 12
CD = 10
And the ∠E = (5x - 10)°
From the Graph, we can see that Angle A is the alternate angle to angle G
Alternate angles are the angles that occur on opposite sides of the transversal line. We can easily spot two interior alternate angles by drawing Z. The value of alternate angles is equal.
thus, ∠A = ∠E
50° = 5x -10
5x = 60
x = 12
Therefore, from the given options the value of x lies in the inequality 2 < x < 22.
