Answer:
P = 28.66 ft
Step-by-step explanation:
So perimeter of half circle
= 2π × 6/2
= 2π × 4/2
= 8π ft/2
= 4 π
Total Perimeter = 6 ft + 8π/2 ft + 10 ft +
= 6 ft + 4 π ft + 10 ft
= 28.666 ft
Total Perimeter = 28.66 ft
PLEASE MARK ME AS BRAINLIEST AND HAVE A NICE DAY
Answer:
28.56
Step-by-step explanation:
The sides of the triangles are already given, so that will be 16. The diameter of the circle is given to be 8, so the radius will be half of it, 4. The circumference of a circle 2πr, so the circumference is 8π. we need to divide this by two because it is a semicircle, so the circumference of the semicircle is 4π. The answer should be 16+4π, and we can substitute in 3.14 for π to get 12.56+16=28.56

An electronic salesman wants to earn $4,000 in November. He receives a base salary of $2000 per month as well as a 10% commission for all sales in that month. How much merchandise will he have to sell to earn the amount of money he wants
20000
Based on the given conditions, formulate:
[tex](4000-2000)\div10\ percent[/tex]
Calculate
[tex]\frac{4000-2000}{0.1}[/tex]
Calculate the sum or difference
[tex]\frac{2000}{0.1}[/tex]
Multiply both the numerator and denominator with the same integer
[tex]\frac{20000}{1}[/tex]
Any fraction with a denominator of 1 is equal to its numerator
[tex]20000[/tex]
I hope this helps you
:)
Step-by-step explanation:
his salary =$2000
his commission should be (to make a total of $4000/month )=$4000-$2000 =$2000
let he should sell x amount over $7000 to get $2000 commission
So, 7% of x = 2000
7x/100 = 2000
x= (2000*100)/7 =28571.43 approx
As he will get commission on sales over $ 7000,so his should sell in a month
=$7000+$28571.43
= $ 35571.43
Determine the equation of the line containing the points given in the table below.
Answer:
BTW where is the table??2k+8=0 Can someone help explain how to solves this please?
Answer:
2k + 8 = 0
2k + 8 - 8 = 0 - 8
2k = - 8
2k/2 = - 8/2
k = - 4
Step-by-step explanation:
you gotta put the 8 on the other side by subtracting and the divide both sides to get k
Answer:
k = -4
Step-by-step explanation:
2k + 8 = 0
Subtract 8 from both sides.
2k = -8
Divide both sides by 2.
k = -4

Everything provided below in picture
Answer:
[tex]1. \frac{4}{3}[/tex]
[tex]2.\frac{1}{3}[/tex]
Step-by-step explanation:
To find the scale factors, you find the length of one side from the image, and divide it by the length of the similar side in the image.
So, for #1, the image side is 8 units, and the pre-image is 6.
8/6 = 4/3
For #2, the image is 3 units, and the pre-image is 9 units.
3/9 = 1/3

Answer:
C. 72
Step-by-step explanation:
The whole angle measures 106 degrees as mentioned on top and we know that angle HFG is 34 degrees because it says so in that angle. Just do this: 106-34. The answer is 72. We subtract because we're finding the remaining/missing number in this problem. If you want to check if your answer is correct, you can add 72 and 34.
Another way you could do this is by just adding each option with 34 to see if you get a total of 106.
Triangle ABC has vertices A(−2,10) , B(4,8) , and C(2,4) .
What are the coordinates of A′B′C′ after triangle ABC has undergone the following transformation?
rotation 90° clockwise about the origin
Enter your answers, as ordered pairs (x, y) , in the boxes.
A′=
B′=
C′=
A'=(10,2)
B'=(8,-4)
C'=(4,-2)
To rotate a point 90° clockwise about the origin,
The new coordinates become (y,-x)
So the first one was A(-2,10)
x=-2 & y=10
The new coordinates become A'(y,-x)
So y=10 and -x=-(-2)=2
A'(10,2)
Answer:
A' =(2,4)
B'=(8,2)
C′=(6,-2)

Answer:
y = 5
x = 0
Step-by-step explanation:
soo i think elimination was this:
so first lets make -x = 3x
so we multiply -3 to the whole equation
3x + 3y = 15
now we eliminate (i think this is elimination)
3x + 5y = 25
-
3x + 3y = 15
----------------------------
0 + 2y = 10
2y = 10
y = 5
now substitute to one of the original equations
3x + 5(5) = 25
3x + 25 = 25
3x = 0
x = 0
now lets check
-0 -5 = -5?
-5 = -5
Ms. Heinz spent 12 dollars on 30 bus tokens for
the field trip. What was the cost of 12 tokens
Answer:
4.8
Step-by-step explanation:
Firstly, you take the ratio 12d/30t(d=dollars, t=tokens). And you switch it to (unknown)d/30t. And if you execute the formula(12 * 12 / 30) you get 4.8.

Josephine is in HR and believes the population mean amount of new employee hires per year in the region is greater than 64. She would like to find evidence of this claim against the standard belief that the population mean amount of new employee hires per year is exactly 64. Josephine gathers a random sample of 56 companies from the region and calculates the sample mean amount of new employees per year to be 64.79 with a sample standard deviation of 2.77. Should the pharmacist reject or fail to reject the null hypothesis given the sample data below? H0:μ=64 versus Ha:μ>64 α=0.05 (significance level) t0=2.13 0.01

The population mean is p = 64
The sample size is n = 56
The sample mean is [tex]\= x = 64.79[/tex]
The standard deviation is [tex]s = 2.77[/tex]
The null hypothesis is [tex]H_o : \mu = 64[/tex]
The alternative hypothesis is [tex]H_a : \mu > 64[/tex]
The test statistics [tex]t = 2.13[/tex]
The level of significance is [tex]\alpha = 0.05[/tex]
The p-value is [tex]0.01 < p-value < 0.025[/tex]

y = sec(x) has a range of f(x) ≤ -1 and f(x) ≥ 1
Thus does not include zero in the range scale.
Extra's:
y = cos(x) has a range of -1 ≤ f(x) ≤ 1
y = cot(x) has infinity range
y = tan(x) has infinity range.
Answer:
sec x
Step-by-step explanation:
Let's set each function equal to zero to see if they have zero in their function.
If there is no solution, then we no solution of zero.
[tex] \cos(x) = 0[/tex]
[tex]x = \frac{\pi}{2} + 2\pi(n)[/tex]
So there is a solution of zero.
[tex] \cot(x) = 0[/tex]
[tex] \frac{ \cos(x) }{ \sin(x) } = 0[/tex]
There answer here is
[tex]x = \frac{\pi}{2} + 2\pi(n)[/tex]
So there is a solution. of zero here
If cot x=0, has a solution of zero, then tan x does as well. Since we can use
[tex] \frac{ \sin(x) }{ \cos(x) } = \tan(x) [/tex]
[tex] \frac{ \sin(x) }{ \cos(x) } = 0[/tex]
The answer here will be
[tex]0 + 2\pi(n)[/tex]
So that leaves sec x.
Proof:
[tex] \sec(x) = \frac{1}{ \cos(x) } [/tex]
1 divided by any number won't equal zero, so the solution will never be 0.

How do you do this question?
Problem 1
You are correct. The answer is choice C.A sequence is just a list of numbers where the order matters. Something like (1,2,3,4,5) is different from (3,1,2,5,4)
A series is where you add up that list of numbers to get a single value. For instance, the sum of the list (1,2,3) is 1+2+3 = 6. This is basically a partial sum when talking about infinite sequences because the next partial sum would be 1+2+3+4 = 10 and the next partial sum would be 1+2+3+4+5 = 15, and so on.
=======================================================
Problem 2
Answer: Choice AWhy is this? Each time we get a partial sum, we're basically forming a new sequence. We're forming a sequence of sums. Going back to the example in problem 1, we had the partial sums (6,10,15). If we keep this process going, we'll have the list of partial sums grow forever and not approach some finite value. Therefore, this series diverges.
If the sums were to slowly get closer to some fixed value, then we would say the series converges.
