5. Evaluate the series 50 + 10 + 2 + . . . 62 The series diverges; it does not have a sum. 62.5
Answer:
62.5
Step-by-step explanation:
By dividing 50 by 10 and 10 by 2 we can find that r, or the common ratio is 1/5, meaning that this series converges, so it is solvable. The formula for a convergent series is [tex]\frac{a_{1}}{1-r}[/tex]. By plugging in 1/5 for r and 50 for [tex]a_{1}[/tex] we can find that the sum of this infinite series is 62.5

If the first equation is multiplied by 2 and then the equations are added, the result is _____.
3x = 13
3x = 3
x = 3
Answer:
Well it would come out to 2x-3y=-9
Step-by-step explanation:
Here's how you solve this problem:
1) Multiply the first equation by 2 (result:2x+2y=8).
2) Add both equations together (result:2x+x+2y-2y=8-5)
3) Simplify (result:3x=3)
The answer is 3x=3.
This could be simplified more, however, to equal x=1, since both sides are divisible by 3.

A car factory takes 6 hours to produce 60 cars. How many hours does the factory take to produce 180 cars?
Final answer:
The factory takes 18 hours to produce 180 cars.
Explanation:
To find out how many hours the factory takes to produce 180 cars, we need to set up a proportion. Since the factory takes 6 hours to produce 60 cars, we can set up the proportion:
6 hours / 60 cars = x hours / 180 cars
Cross-multiplying, we get:
6(180) = 60(x)
Simplifying, we have:
1080 = 60x
Dividing both sides by 60, we find:
x = 18
So, the factory takes 18 hours to produce 180 cars.

Step-by-step explanation:
A number is divided by 3 and then 5 is subtracted from the quotient the result is 1. Whats the number?
ANSWER
The number is 18.
EXPLANATION
Let the number be x.
When this number is divided by 3, we obtain the quotient,
[tex] \frac{x}{3} [/tex]
When 5 is subtracted from this quotient, we get,
[tex] \frac{x}{3} - 5[/tex]
If the result is 1, then we have;
[tex] \frac{x}{3} - 5 = 1[/tex]
We group similar terms to get,
[tex] \frac{x}{3} = 1 + 5[/tex]
This gives us,
[tex] \frac{x}{3} = 6[/tex]
Multiply both sides by 3.
[tex]x = 6 \times 3[/tex]
[tex]x = 18[/tex]
Therefore the number is 18.

A survey of eating habits showed that approximately 4% of people in a certain city are vegans. Vegans do not eat meat, poultry, fish, seafood, eggs, or milk. A restaurant in the city expects 350 people on opening night, and the chef is deciding on the menu. Treat the patrons as a simple random sample from the city and the surrounding area, which has a population of about 600,000. If 17 vegan meals are available, what is the approximate probability that there will not be enough vegan mealslong dashthat is, the probability that 18 or more vegans will come to the restaurant? Assume the vegans are independent and there are no families of vegans.
The approximate probability that there will not be enough vegan meals is 94.88%.
Explanation:To calculate the approximate probability that there will not be enough vegan meals, we need to find the probability that 18 or more vegans will come to the restaurant. Since the survey showed that approximately 4% of people in the city are vegans, we can use this information to estimate the probability.
First, we find the number of vegans in the city and surrounding area by multiplying the total population by the percentage of vegans: 600,000 * 0.04 = 24,000.
Next, we calculate the probability of 18 or more vegans showing up out of 24,000 by using a binomial distribution with n = 350 (the number of people expected on opening night) and p = 0.04 (the probability of a person being vegan). We then sum the probabilities for 18, 19, 20, ..., 350 vegans.
Using a calculator or statistical software, we find that the approximate probability is 0.9488, or 94.88%.

Find the annual interest rate I equals $562.50 P equals to $1500 T equals five years
Answer: The rate is 7.5%.
Step-by-step explanation: The formula to calculate simple interest is:
Interest = Principal x Rate x Time
So, we need to plug our information into the formula:
$562.50 = $1,500 x R x 5
Now, perform the multiplication that you can:
$562.50 - $7,500R
Next, divide both sides by $7,500:
.075 = R
Therefore, the rate is 7.5%.
Please help!! Double points! write the ratios for sin X and cos X (Image attached)
Will give BRAINLIEST to the person correct answer and please please show your work :))
Answer:
The ratio for sin(X) is [tex]\frac{\sqrt{119} }{12}[/tex]
The ratio for cos(X) is [tex]\frac{5}{12}[/tex]
Step-by-step explanation:
- The ratio of the sine of a right triangle is:
[tex]sin(\alpha)=\frac{opposite-side}{hypotenuse}[/tex]
Since we need the ratio for angle X, [tex]\alpha =X[/tex]. From the picture we can infer that the opposite side of X is [tex]\sqrt{119}[/tex]. The hypotenuse (the side opposite to the right angle) is 12, so replacing the values:
[tex]sin(X)=\frac{\sqrt{119} }{12}[/tex]
- The ratio of the cosine is:
[tex]cos(\alpha)=\frac{adjacent-side}{hypotenuse}[/tex]
Similarly, [tex]\alpha =X[/tex], adjacent side = 5, and hypotenuse = 12, so
[tex]cos(X)=\frac{5}{12}[/tex]
Answer:
Sin X =√119/12
Cs X = 5/12
Step-by-step explanation:
It is given a right angled triangle.
Points to remember
Sin θ = Opposite side/Hypotenuse
Cos θ = Adjacent side/Hypotenuse
To find the value of Sin X
Here X is an angle
Opposite side = √119
Hypotenuse = 12
Sin X = Opposite side/Hypotenuse = ZY/XY = √119/12
To find the value of Cos X
Adjacent side of X = 5
Cos X = Adjacent side/Hypotenuse = XZ/XY = 5/12

Nakesha’s Sporting Goods is running a sale on golf shoes this week. The sale price is $95.98. The shoes cost Nakesha’s $63.45. What is the markup rate based on cost?
Answer:
Markup rate = 0.512 or 51.2%
Step-by-step explanation:
Mark up rate is the increase amount added to the original price.
Sales Price = $95.98
Original Price= $63.45
Gross profit margin = Sales Price - Original cost
= $95.98 - $63.45
= $ 32.53
Mark up Rate = Gross profit margin/ original price
= 32.53 / 63. 45
= 0.51
converting into percentage by multiplying with 100
Mark up Percentage = 0.512 * 100
= 51.2 %
What is the value of the remainder if 10x4 – 6x3 + 5x2 – x + 1 is divided by x – 3?
Answer:
Remainder is 691.
Step-by-step explanation:
Given function is [tex]10x^4-6x^3+5x^2-x+1[/tex].
Now we need to find remainder if we divide given function [tex]10x^4-6x^3+5x^2-x+1[/tex] by (x-3)
(x-3) means plug x=3 into [tex]10x^4-6x^3+5x^2-x+1[/tex] to find remainder.
[tex]10x^4-6x^3+5x^2-x+1[/tex]
[tex]=10(3)^4-6(3)^3+5(3)^2-(3)+1[/tex]
[tex]=10(81)-6(27)+5(9)-(3)+1[/tex]
[tex]=810-162+45-3+1[/tex]
[tex]=856-162-3[/tex]
[tex]=856-165[/tex]
[tex]=691[/tex]
Hence remainder is 691.
Answer:
The remainder = 691
Step-by-step explanation:
Let p(x) = 10x⁴ - 6x³ + 5x² - x + 1
We have to divide p(x) by (x - 3)
To find the remainder we have to find p(3)
To find the remainder
p(x) = 10x⁴ - 6x³ + 5x² - x + 1
p(3) = 10 * (3)⁴ - 6*(3)³ + 5* (3)² - 3 + 1
= (10 * 81 ) - ( 6 * 27 ) + (5 * 9) - 3 + 1
= 810 - 162 + 45 - 3 + 1 = 691
Therefore the remainder is 691

Sadie made a rectangular cake. If she wants to cut it into 1/8 portions,how many portions can she cut?
Answer:
8
Step-by-step explanation:
If each portion is 1/8 of the cake, there are 8 equal-size portions. That is what the denominator of the fraction means.
Sadie can cut the rectangular cake into 8 portions if each portion is 1/8 of the whole cake.
To determine how many portions Sadie can cut the rectangular cake into if each portion is 1/8, we need to understand that she is essentially dividing the cake into 8 equal parts.
Here's a step-by-step explanation:
Whole Cake: The entire rectangular cake represents one whole (1).
→ Portion Size: Each portion is 1/8 of the whole cake.
→ Calculation: We divide 1 by 1/8. Mathematically, this is the same as multiplying by the reciprocal,
so 1 ÷ (1/8) = 1 × 8
= 8.
Therefore, Sadie can cut the rectangular cake into 8 portions of size 1/8 each.

If you know the radius, r, of a circle, what do you multiply r by to get the circle's CIRCUMFERENCE?
Answer:
multiply the radius by 2π
Step-by-step explanation:
The formulas for circumference of a circle is
C = πD where D is the diameter,
or
C = 2πr where r is the radius.
Either formula is correct, but we will work with the second one since the question is asking about radius.
We see that 2π(r) = the circumference, so multiply r by 2π to get the circumference
Hello there! How are you doing? I am doing fine! I'll answer the question now.
So basically when wanting to find the circumference of a circle you simply use the formula, C = 2 times PI times R. PI is the infamous number known for 3.1415912654... and the R represents the radius. You would multiply 2 times PI and then after getting that you would basically multiply it by the radius. And then that would be the circumference and be the answer to any problem you face like this. Know that diameter is 2 times the radius and that all.
Hope this helped! Your welcome! I can help with other history stuff too! And byee! :)
What number represents the same amount as 2 hundreds ++plus 14 tens ++plus 3 ones?
343 is the answer because 14 tens is 1 hundred and 4 tens
The number that represents 2 hundreds, 14 tens, and 3 ones is 343, by adding each place value: 200 + 140 + 3.
Explanation:The student asks how to represent the quantity consisting of 2 hundreds, 14 tens, and 3 ones in a single number.
To solve this, we can convert each quantity to its respective place value in the decimal system and sum them.
Two hundreds is equal to 200 (2 x 100), 14 tens equals 140 (14 x 10), and 3 ones equals 3 (3 x 1).
Adding them together gives us 200 + 140 + 3 = 343.
Points A and B split the circle into two arcs. Measure of minor arc is 150°. Point M splits major arc with the ratio 2:5 (point M is closer to point B). Find m?BAM.
Answer:
∠BAM=30°
Step-by-step explanation:
Points A and B split the circle into two arcs. If the measure of minor arc AB is 150°, then the measure of the major arc AB is 360°-150°=210°.
If point M splits major arc with the ratio 2:5, then
∠BOM=2x°;∠AOM=5x°.Angles BOM and AOM together form angle with the measure 210°, thus
2x+5x=210,
7x=210,
x=30°
and ∠BOM=60°, ∠AOM=150°.
Consider isosceles triangle BOM. In this triangle,
∠OBM=1/2(180°-60°)=60°.
Consider isosceles triangle AOB. In this triangle,
∠OAB=1/2(180°-150°)=15°.
Consider isosceles triangle AOM. In this triangle,
∠OAM=1/2(180°-150°)=15°.
Thus, ∠BAM=15°+15°=30°
Answer:
arc BAM = 300°
Step-by-step explanation:
Refer to the figure attached.
arc AB = 150°
then:
arc AMB = 360° - 150° = 210°
arc AMB can be decomposed as:
arc AM + arc MB = arc AMB (eq. 1)
From data:
arc MB/arc AM = 2/5
arc MB*(5/2) = arc AM (eq. 2)
Replacing equation 2 into equation 1:
arc MB*(5/2) + arc MB = 210°
arc MB*(7/2) = 210°
arc MB = (2/7)*210° = 60°
On the other hand:
arc MB + arc BAM = 360°
arc BAM = 360° - 60° = 300°
The function f(x)=x^2-4x+4 is shifted 3 units to the right to create g(x). What is g(x)
Answer:
g(x) = x² - 7x + 16Step-by-step explanation:
f(x) + n - shift the graph of f(x) n units up
f(x) - n - shift the graph of f(x) n units down
f(x - n) - shift the graph of f(x) n units to the right
f(x + n) - shift the graph of f(x) n units to the left
===================================
f(x) = x² - 4x + 4 shifted 3 units to the right. Therefore g(x) = f(x - 3):
g(x) = (x - 3)² - (x - 3) + 4 use (a - b)² = a² - 2ab + b²
g(x) = x² - 2(x)(3) + 3² - x - (-3) + 4
g(x) = x² - 6x + 9 - x + 3 + 4 combine like terms
g(x) = x² + (-6x - x) + (9 + 3 + 4)
g(x) = x² - 7x + 16
