Chelsea takes the bus to school, but she walks home. The bus travels to the school at an average speed of 45 miles per hour. While going home from school, Chelsea walks at a speed of 2.5 miles per hour.
In total, she takes 1 hour to travel to school and back. If t is the time it takes to go to school by bus, the equation that will help find the time it takes Chelsea to get to school on the bus is ANSWER1
. The equation will have ANSWER2
PLS ANSWER ANSWER 1 AND 2
Answer:45 * t = 2.5 * (1-t)...the equation will have one solution.
Step-by-step explanation:
For this case, the first thing you should know is:
d: v * t
Where,
d: distance
v: speed
t: time
To go to school by bus we have:
d = 45 * t
To return from school we have:
d = 2.5 * (1-t)
how the distance is the same:45 * t = 2.5 * (1-t)

W 3 Aisha has $100 saved from her job. She wants to buy as many charms for her bracelet, at $4 each and earrings at $5 per set, as she can without spending all of her money. The inequality represents her spending, where x is the number of charms and y is the number of sets of earrings. 4x + 5y < 100
Simplifying 4x + 5y < 100 Solving 4x + 5 < 100. Solving for variable 'x' move all terms containing x to the left, all other terms to the right.

Consider the series
[infinity]
∑ (-1)^n (x+1)^n/ (n+1)!
n=0
a. Find the series' radius and interval of convergence.
b. For what values of x does the series converge absolutely?
c. For what values of x does the series converge coditionally?
(a) If
[tex]f(x)=\displaystyle \sum_{n=0}^\infty (-1)^n \frac{(x+1)^n}{(n+1)!}[/tex]
then by the ratio test, the series converges for all x, since
[tex]\displaystyle \lim_{n\to\infty} \left| \frac{ (-1)^{n+1} \frac{(x+1)^{n+1}}{(n+2)!} }{ (-1)^n \frac{(x+1)^n}{(n+1)!} } \right|=\lim_{n\to\infty}\frac{|x+1|}{n+2}=0[/tex]
so the series radius of convergence is ∞ and the interval of convergence is (-∞, ∞).
(b) The series converges everywhere absolutely, because the ratio test for
[tex]\displaystyle \sum_{n=0}^\infty \frac{|x+1|^n}{(n+1)!}[/tex]
also shows the radius of convergence is ∞.
(c) The series converges absolutely, so conditional convergence is moot.
find the distance between (-8,7) and (13,-1)
Answer:
22.4722
Step-by-step explanation:
To answer this question we need to use the distance formula. The distance formula is as follows:
[tex]d = \sqrt{(x2 - x1)^2+(y2 - y1)^2}[/tex]
Now, let's identify what each variable is:
x2 = 13
x1 = -8
y2 = -1
y1 = 7
Next, let's put these into the equation:
[tex]d = \sqrt{(13 - (-8))^2 + (-1 -7)^2}[/tex]
Time to solve the equation:
[tex]d = \sqrt{(21)^2+(-8)^2} \\d = \sqrt{441 + 64} \\d = \sqrt{505} \\d = 22.4722[/tex]
Therefore, the distance between the points of (-8,7) and (13,1) is 22.4722.
I hope this helps!!

Scarlett is playing a video game. She spends 900 minerals to create 18 workers. Each worker costs the same number of minerals.
So you would do 900÷18 to get the amount each worker is worth, which would be 50 minerals.
Answer: m=50w
Step-by-step explanation:
When you divide 900 by 18, you get 50.
Since we are trying to find the amount of minerals per worker, m is the first variable. w is the second because that is the number of workers you can get with the minerals Scarlett has.

Answer:
x
Step-by-step explanation:
Answer:
when you are graphing do x first
Step-by-step explanation:
The slope of a line is usually represented by the letter m. (x1, y1) represents the first point whereas (x2, y2) represents the second point. It is important to keep the x-and y-coordinates in the same order in both the numerator and the denominator otherwise you will get the wrong slope.

Round 6.487 and 2.049 to the hundredths place. What is the sum of the rounded numbers? *
Answer:
8.54
Step-by-step explanation:
If thousandth's place is ≥ 5 , then add 1 to the hundredth place.
6.487 = 6.49
2.049 = 2.05
6.487 + 2.049 = 6.49 + 2.05 = 8.54
Louis and Max are contestants in a jellybean-eating contest. Louis eats 18 jellybeans
in 30 seconds. Max eats 24 jellybeans in 40 seconds.
Answer: They ate at the same pace.
Step-by-step explanation: assuming you want to know who ate more faster you can do 18 / 30 and 24 / 4 to find out who ate more in 10 seconds each.
18 / 3 = 6 and 24 / 4 = 6. So they ate at the same speed / pace.
