Step-by-step explanation:
The sum of the first 50 terms in this geometric series is 11.00.
What is a geometric series?When all the terms of a geometric sequence are added, then that expression is called geometric series.
Lets suppose its initial term is f=a , multiplication factor is r
and let it has total n terms, then, its sum is given as:
[tex]S_n = \dfrac{a(r^n-1)}{r-1}[/tex]
(sum till nth term)
We are given that;
n=50
Series= 1+10/11+100/121
Now,
To find the sum of the first 50 terms in this geometric series, we need to use the formula:
Sum = [tex]a1(1 - r^n) / (1 - r)[/tex]
where a1 is the first term, r is the common ratio, and n is the number of terms. We can identify that the first term is 1, the common ratio is 10/11, and the number of terms is 50. Plugging these values into the formula, we get:
Sum = 1(1 - (10/11)^50) / (1 - 10/11) Sum = (1 - 0.000000000000000000000000000000000000000000000001) / (1/11) Sum = (0.9999999999999999999999) / (0.09090909) Sum = 10.99998
Rounding this result to two decimal places, we get:
Sum = 11.00
Therefore, by the given geometric sequence the answer will be 11.00.

Rosalie is training for a marathon. She jogs for 30 minutes at a rate of 5 miles per hour, then she decreases her speed over a period of time and walks for 60 minutes at a rate of 3 miles per hour.
What is the range of this relation?
A.
0 ≤ y ≤ 5
B.
y ≤ 5
C.
y ≥ 0
D.
3 ≤ y ≤ 5
Answer:
3 ≤ y ≤ 5
Step-by-step explanation:
Rosalie is training for a marathon. She jogs for 30 minutes at a rate of 5 miles per hour, then she decreases her speed over a period of time and walks for 60 minutes at a rate of 3 miles per hour.
Therefore, the speed (y) of Rosalie ranges from 5 mph to 3 mph including the values.
So, the range of this relation is 3 ≤ y ≤ 5. (Answer)
We can see here that the range of this relation is: D. 3 ≤ y ≤ 5
How we arrived at the solution?To determine the range of this relation, let's first calculate the distances Rosalie covers during each phase of her training:
Jogging phase:
Time = 30 minutes = 0.5 hours
Speed = 5 miles per hour
Distance = Speed × Time = 5 × 0.5 = 2.5 miles
Walking phase:
Time = 60 minutes = 1 hour
Speed = 3 miles per hour
Distance = Speed × Time = 3 × 1 = 3 miles
Now, let's consider the range of distances Rosalie covered during her training:
The minimum distance she covered is 2.5 miles (jogging phase), and the maximum distance is 2.5 + 3 = 5.5 miles (jogging + walking phases).
The given options are:
A. 0 ≤ y ≤ 5
B. y ≤ 5
C. y ≥ 0
D. 3 ≤ y ≤ 5
Since the minimum distance covered is 2.5 miles and the maximum distance covered is 5.5 miles, the correct option that represents the range of this relation is:
D. 3 ≤ y ≤ 5

Find the inequality represented by the graph
Answer:
[tex]y<\frac{1}{4}x+3[/tex]
Step-by-step explanation:
we know that
The solution of the inequality in the graph is the shaded area below the dashed line
The slope of the dashed line is positive
The y-intercept of the dashed line is (0,3)
The dashed line pass through the points (0,3) and (4,4)
The slope of the dashed line is
[tex]m=(4-3)/(4-0)=1/4[/tex]
The equation of the dashed line in slope intercept form is
[tex]y=\frac{1}{4}x+3[/tex]
therefore
The inequality represented by the graph is

Damian has a spinner. He spun the arrow 60 times and it landed on green 12 times.
Based on the data, how many times would the arrow land on green if Damian only spun it 10 times?
Answer:
it would be 2
Step-by-step explanation:
what you do to find the probability is to divide so you divide 60 from 12 which automatically = 5 so then you divide 10 from 5 which gives you 2
The Correct Answer is 2 times
On spinning 60 times domain landed arrow 12 times.
On 1 time spinning, he will land an arrow [tex]\frac{60}{12}[/tex]=5
∴ number of times arrow landed on green = [tex]\frac{10}{5}[/tex]=2
How do you calculate probability?Divide the number of events by the number of possible outcomes. This will give us the probability of a single event occurring. In the case of rolling a 3 on a die, the number of events is 1 (there's only a single 3 on each die), and the number of outcomes is 6.

Jasmine has 84 flowers available to make bouquets for the farmer's market. To make the bouquets more appealing to the
she would like to have an odd number of flowers in each. She wants to use all of the available flowers. To meet lasmines
requirements, how many flowers could she put in each bouquet?
HELP PLZZ
Answer:
Jasmine could have 84 bouquets with 1 flower in each,28 bouquets with 3 flower in each,12 bouquets with 7 flower in each or 4 bouquets with 21 flower in each.Step-by-step explanation:
The total number of flowers that jasmine has to make bouquets is 84.
We need to note that she want to use all the flowers.
Now let us write down all factors of 84.
84= 1 * 84 ....(1)
= 2 * 42 ....(2)
= 3 * 28 ....(3)
= 4 * 21 ....(4)
= 6 * 14 .....(5)
= 7 * 12 ....(6)
Now all we need is odd number of flowers in each bouquet,i.e,
All the numbers written in the right hand side of the above 1 to 6
numbered equations are factors of 84.
Since Jasmine wanted no flowers to be wasted so we can assume that number of flowers in each bouquet must be an odd factor of 84.
Therefore, odd factors of 84 are 1,3,7,21.
So Jasmine could have 84 bouquets with 1 flower in each,28 bouquets with 3 flower in each,12 bouquets with 7 flower in each or 4 bouquets with 21 flower in each.

m∠JKL = 87°
m∠KJL = 58°
m∠KLJ = 35°
m∠KLM = 145°
Step-by-step explanation:
The exterior angle theorem says that the sum of two interior angles is equal to the exterior angle
In the given triangle, the interior angles are:
m∠K = (7x-32)°
m∠J = (5x-27)°
The interior angle is:
m∠L = (9x-8)°
So writing mathematically
m∠J+m∠K = m∠L
[tex]7x-32+5x-27 = 9x-8\\12x -59 = 9x - 8\\12x-9x = 59-8\\3x = 51[/tex]
Dividing both sides by 3
[tex]\frac{3x}{3} =\frac{51}{3}\\x = 17[/tex]
Now m∠JKL
= [tex]7x-32\\=7(17) - 32\\=119-32\\=87[/tex]
m∠KJL
[tex]= 5x-27\\=5(17)-27\\=85-27\\=58[/tex]
m∠KLJ
[tex]=188-9x\\=188-153\\=35[/tex]
m∠KLM
[tex]=9x-8\\=9(17) -8\\=153-8\\=145[/tex]
Hence,
x = 17
m∠JKL = 87°
m∠KJL = 58°
m∠KLJ = 35°
m∠KLM = 145°

Step-by-step explanation:
If she makes 12% commission off of it, she makes [tex]\frac{22540}{1} *\frac{12}{100}=$2704.80\\[/tex]
Final answer:
To calculate Amelia's commission, convert the 12% commission rate to a decimal (0.12) and multiply it by her sales of $22,540. Amelia will earn a commission of $2,704.80.
Explanation:
The question asks us to calculate how much commission Amelia makes on her sales of hand-crafted jewelry, given a commission rate of 12% and sales amounting to $22,540. To find the commission, we need to multiply the total sales by the commission rate expressed as a decimal.
Steps to Calculate Commission
Convert the commission rate from a percentage to a decimal by dividing by 100: 12% / 100 = 0.12.
Multiply the sales amount by the decimal commission rate: $22,540 × 0.12 = $2,704.80.
Amelia's commission for selling $22,540 worth of jewelry is $2,704.80.

How long is a guy wire reaching from the top of a 6ft. Pole to a point on the ground 4ft. From the pole
Answer:
the guy wire is 7.211 ft long
Step-by-step explanation:
Notice that we are in the presence of a right angle triangle formed by: the height (the standing 6 ft pole), the base (the distance from the pole to the anchoring point on the ground), and the actual guy wire. See attached image for reference.
Notice that since pole and ground are perpendicular to each other (at 90 degrees) , the guy wire forms what is called the "hypotenuse" (longest side) of the right angle triangle. We can therefore use the Pythagorean Theorem to solve this problem with the formula for the hypotenuse:
[tex]Hypotenuse=\sqrt{side1^2 +side2^2} \\Hypotenuse= \sqrt{6^2+4^2}\\Hypotenuse=\sqrt{36+16} \\Hypotenuse=\sqrt{52} \\Hypotenuse=7.2111\, ft[/tex]

Now substituting the values we get
[tex]p(B) = \frac{4}{6}[/tex]
[tex]p(B) = \frac{2}{3}[/tex]
but we need complement of B so
[tex]p(\textrm{complement of B)} = 1 - p(B)\\p(\~B) = 1 - p(B)\\p(\~B) = 1 - \frac{2}{3}\\ =\frac{1}{3} \\[/tex]

Spotlight Dance increased the number of dancers on its competition team. Last
season, there were 10 dancers this season, there were 18. What was the perecent
of increase?
Answer:
80%
Step-by-step explanation:
To find percentage increase, we use the following formula:
Percentage Increase = [tex]\frac{New-Old}{Old}*100[/tex]
Here
New means the latest value (which is 18 dancers)
Old means the previous value (which is 10 dancers)
The Multiplication by 100 is to convert the decimal answer to percentage.
So, we have:
New = 18
Old = 10
Now we substitute and find:
[tex]\frac{New-Old}{Old}*100\\\frac{18-10}{10}*100\\\frac{8}{10}*100\\80[/tex]
So, there was an increase of 80%

Suppose yoko borrows $3500 at an interest rate of 4% compounded each year Find the amount owed at the end of 1 year
Amount owed at the end of 1 year is 3640
Solution:Given that yoko borrows $3500.
Rate of interest charged is 4% compounded each year
Need to determine amount owed at the end of 1 year.
In our case :
Borrowed Amount that is principal P = $3500
Rate of interest r = 4%
Duration = 1 year and as it is compounded yearly, number of times interest calculated in 1 year n = 1
Formula for Amount of compounded yearly is as follows:
[tex]A=p\left(1+\frac{r}{100}\right)^{n}[/tex]
Where "p" is the principal
"r" is the rate of interest
"n" is the number of years
Substituting the values in above formula we get
[tex]\mathrm{A}=3500\left(1+\frac{4}{100}\right)^{1}[/tex]
[tex]\begin{array}{l}{A=\frac{3500 \times 104}{100}} \\\\ {A=35 \times 104} \\\\ {A=3640}\end{array}[/tex]
Hence amount owed at the end of 1 year is 3640
