Step-by-step explanation:
Solve for k
Please help!
Answer:
k = 0.3
Step-by-step explanation:
Multiply both sides by 2 * k
3 = 5 * 2*k Combine like terms on the right
3 = 10 * k Divide by 10
k = 3/10
k = 0.3

A triangle is shown with side lengths labeled 0.3x plus 24, 5x, and 0.2x minus 15.
Answer: The expression is 5.5x + 9 for the perimeter of the triangle described.
Step-by-step explanation: Add the three lengths given to find the perimeter.
0.3x + 24,
+ 5x,
+ 0.2x - 15 Combine like terms

A train traveling at 37 M.P.H. had its speed increased by 22 ft. per sec.
If 88 ft./sec. = 60 M.P.H., then the train is now traveling at M.P.H.
Answer:
52 mph
Step-by-step explanation:
If 88 ft/sec = 60 mph
The 22 ft/ sec is 60/4 = 15 mph
This is so because 88/22 is 4
So we simply proceed to add this to the previous speed in mph
That gives a total of 15 + 37 = 52 mph
charles buys a pair of sneakers for 6.30. he wants to re-sell the pair of sneakers. he marks up the price by 40%. how much will he sell the pair of sneakers?
Answer:
Step-by-step explanation:
if Charles bought the sneakers for 6.30 and wants to re-sell them with 40% more,
first lets see how much is 40% of 6.30
(6.30*40)/100=2.52
he will resell the shoes with
6.30+2.52=8.82
Answer:
$[tex]8.82[/tex]
Step-by-step explanation:
[tex]6.30 + 0.4\times6.30 = 8.82[/tex]
[tex]\therefore[/tex] Charles will sell the sneakers at a price of $[tex]8.82[/tex]

How many solutions does 46x– 23 = 46x + 23 have
Answer:
no solution
Step-by-step explanation:
Let's first try to solve this.
Notice that there is a 46x term on both sides, so we can subtract both sides by 46x, leaving us with:
-23 = 23
Well... this is a false statement: -23 does not equal 23.
Thus, this as no solution.
Answer:
No solutions found
Step-by-step explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
46*x - 23 - (46*x + 23) = 0
Equations that are never true
Solve : -46 = 0
This equation has no solution.
A non-zero constant never equals zero.

Would the phrase
“Net Change” mean I would subtract the given numbers? I’m on a post test and I’m a little confused. Please answer if you know.
Answer:
Net change means the differnce between the before result and the after result. You would subtract the numbers, but if you have a gain(the before result smaller than after result) you would do its absolute value. If it's a loss(the before result bigger than after result) you would put a negative behind its absolute value.
e.g. if 2019 had $1 net worth and 2020 had $2 net worth, since 2>1 it would be |2-1| = 1. If 2019 had $2 net worth and 2020 had $1 net worth, since 1<2 there would be a - |2-1| = -1 net change.
However, if there is no change it would be just 0.

When it comes to two equations, when their slopes are the same, they are parallel. If the slopes are negatively reciprocated then they are perpendicular.
Starting at the same point, Tom and Juanita go biking in opposite directions. If Tom rides at a speed of 20 mph, and Juanita rides at a speed of 20 mph, how far apart will they be in 2 hours?
Answer:
Concept: Mathematical Analysis
They go in opposite directions They start at the same point, let's define that as (0,0) on the ordinary differntiable x-y axis Hence Tom can ride 20 units left in one hour and Juanita can ride 20 units right in one hour.We want to know the distance they are at the end of 2 hours So we set up the equation y= 20(x)Let x be the hours and y be the distance So 20×2=40 miles At the end of 2 hours they will be 40 miles apart assuming constant rate of change and a starting point of (0,0)This question is worth 100 points please answer now.

Show all work to identify the asymptotes and zero of the function f of x equals 4 x over quantity x squared minus 16.
Answer:
The vertical asymptotes occur at x = 4 and x = -4
The zero of the function is (0, 0)
Step-by-step explanation:
The given function is [tex]f(x) = \dfrac{4\cdot x}{x^2 - 16}[/tex]
Therefore, we have;
[tex]f(x) = \dfrac{4\cdot x}{x^2 - 16} = \dfrac{4\cdot x}{(x - 4) \cdot (x + 4)}[/tex]
The asymptote is given at the value of x for which the denominator = 0, therefore, the asymptote are the values of x that make the denominator of the equation equal to zero, which are given as follows
For the asymptote, the denominator = x² - 16 = (x - 4)·(x + 4) = 0
Therefore, the vertical asymptotes are the lines x = 4 and x = -4.
The zero of the function is given as follows;
[tex]f(x) = \dfrac{4\cdot x}{x^2 - 16} = 0[/tex]
Therefore, 4·x = (x - 4)·(x + 4) × 0 = 0
x = 0/4 = 0
Therefore, when f(x) = 0, x = 0 and the zero of the function = (0, 0).

Factor the expression:
280z - 25y - 30
PLS ASAP
Answer:
[tex]5(56z - 5y - 6)[/tex]
Step-by-step explanation:
Forst step is finding a common factor, you can do this easily by looking at the ones digit. All 3 values end in 0 or 5, so a factor is definately 5.
We now divide all values by 5.
[tex]280z \div 5 = 56z \\ (- 25y) \div 5 = ( - 5y) \\ ( - 30) \div 5 = ( - 6)[/tex]
Once you get a prime number after factoring, that is the GCF, Greatest Common Factor. We can make an equation like what is below to show oir factored answer.

The sums of n terms of two arithmetic progressions are in the ratio 5n+4: 9n+6. Find the ratio of their 18th terms.
Answer:
179:321
Step-by-step explanation:
If Sn is the sum of the first n term of a sequence, the ratio will be expressed as:
Sn/S'n = 5n+4/9n+6
The sum of nth term of a sequence is expressed as
Sn = n/2[2a+(n-1)d]
The expression becomes
{n/2[2a+(n-1)d]}/{n/2[2a+(n-1)d']} = 5n+4/9n+4
Open the bracket
a+(n-1/2)d/a+(n-1/2)d' = 5n+4/9n+4
Since the 18th tern is expressed as
T18 = a+(18-1)d
T18 = a+17d
The expression becomes
T18/T'18 = a+(n-1/2)d/a+(n-1/2)d'
a+17d/a'+17d' = a+(n-1/2)d/a+(n-1/2)d'
Compare and contrast to get n
On comparing both sides of the equation
17 = n-1/2
n-1 = 17×2
n-1 = 34
n = 34+1
n = 35
If the nth term is 5n+4
18th term will be 5(35)+4 = 179
If the nth term is 9n+6
18th term will be 9(35)+6= 321
Hence the ratio of their 18th term will be 179:321
n-6+4=24 solve for n

What is the y-coordinate of point W?
PLS ASAP
============================================================
Explanation:
Draw a horizontal line from W to the y axis. You should arrive somewhere between -1 and -2. While this isn't exact, it looks like we should arrive right at the middle of -1 and -2; therefore we should get to -1.5
The y coordinate of W is -1.5
Keep in mind this is based on the assumption we reach the halfway point. Unfortunately, W is not on any horizontal grid lines to be able to determine exactly where W is along the y axis.

Calculate simple interest : $125. 4 years, at 10% interest ..(how much is the interest alone?)
Here we have been clearly given with Principal, time period and rate of interest.

S.I. is simple Interest R is rate of interest T is timePutting the values :

https://brainly.com/question/26734922The hemmings borrowed $3 000 for home improvements. They repaid the loan and $600 in simple interest four years later. What simple annual interest rate did they pay
Answer:
5%
Step-by-step explanation:
Given that:
Principal = $3000
Simple Interest paid = $600
Period = 4 years
Simple interest = principal * rate * time
$600 = $3000 * rate * 4
$600 = $12000 * rate
Rate = $600 /$12000
Rate = 0.05
Hence, simple interest rate paid = (0.05 * 100%) = 5%
