Answer:
The total in the account after 10 years would be: $14,190.68
Step-by-step explanation:
Recall the formula for continuous compounding:
[tex]A=P\,e^{r\,t}[/tex]
where "A" is the accrued value after t years (what we need to find), "P" is the principal invested (in our case $10,000), "r" is the interest rate in decimal form (in our case r = 0.035), and "t" is the time in years (in our case t = 10). Therefore the formula becomes:
[tex]A=P\,e^{r\,t}\\A=10000\,\,e^{0.035\,*\.10}\\A=14190.68[/tex]
Therefore the total in the account after 10 years would be: $14,190.68
In a football game, the home team scored 1 touchdown and one extra point during every quarter. How many points did the home team have at the end of the game?
Answer:

Step-by-step explanation:
A touch down is 6 points and an extra point is 1 point
There are 4 quarters
6+1 = 7
4 quarters
4*7 = 28
They scored 28 points

Please answer these simultaneous equations ASAP. Thank you (lots of points only for full answers)
Step-by-step explanation:
for number 4:
2x + 5y = -10
2x - y = 8
subtract it
6y = -18
y = 6/-18
y = -0.3
now go back to the first equation
2x + 5 x -0.3 = -10
2x -1.5 = -10
2x = -8.5
-4.25
x = -4.25, y = -0.3

Step-by-step explanation:
Tim and jane both work for a company that sells boxes of breakfast cereal the boxes of cereal cost 3 pounds and the amount of cereal in each box weighs 160g the company wants to have a special offer here is Tim's idea for the special offer: PUT 25% MORE CEREAL IN EACH BOX AND DO NOT LOWER THE PRICE here is Jane's idea: REDUCE THE PRICE AND DO NOT CHANGE THE AMOUNT OF CREAL IN EACH BOX Jane wants her idea to give the same value of money as Tim's idea by what percentage does she need to reduce the price?
Answer:
In order to give the same value for money as Tim's idea, Jane has to reduce the price by 25%
Step-by-step explanation:
The given parameters are;
Cost of each box of breakfast cereal = 3 pounds
Amount of cereal in each box of breakfast cereal = 160 g
160 g of cereal = 100%
25% of one box of cereal = 25% of 160 g = (25/100)×160 g= 40 g
Given that Jane wants her idea to give the same value of money as Tim's idea, we have;
160 g of cereal costs 3 pounds
1 g of cereal will cost 3/160 pounds
40 g of cereal will cost 40*3/160 = 3/4 pounds
Therefore, the percentage 3/4 pound is of 3 pounds = [tex]\dfrac{\frac{3}{4} }{3} \times 100 = 25 \%[/tex]
Which gives, Jane has to reduce the price by 25% to give the same value for money as Tim's idea.
To give the same value of money as Tim's idea, she need to reduce the price by 20%.
Given that:
Cost of one box of breakfast cereal is 3 pounds.
Weight of 1 box of cereal is 160g.
Tim's idea is to put 25% more cereal.
Let Jane's idea is to reduce price by x pounds such that the value of the item is same as that after applying Tim's idea.
Value in case of Tim's idea:
[tex]160g + \dfrac{160 \times 25}{100} \: \: in \: \: 3 \: pounds\\\\200g \: \: in \: \: 3 pounds\\1g \: \: in \: \: \dfrac{3}{200} \: pounds[/tex]
Value in case of Jane's idea:
[tex]160g \: \: in \: \: (3-x) \: pounds\\\\1g \: \: in \: \: \dfrac{(3-x)}{160} \: pounds\\[/tex]
Since values have to stay same, thus we have:
[tex]\dfrac{3}{200} = \dfrac{3-x}{160}\\\\\dfrac{12}{5} = 3-x\\\\5x = 3\\\\x = \dfrac{3}{5}\\\\x = 0.6 \:pounds[/tex]
To calculate percentage, we can do as follows:
[tex]\begin{aligned}percentage &= \dfrac{x \times 100}{3}\\&= \dfrac{60}{3}\\&= 20\end{aligned}[/tex]
Thus, to give the same value of money as Tim's idea, she need to reduce the price by 20%.

Answer:
$216 for the Train Ride and visit to the Museum.Step-by-step explanation:
There are two values to find and add together.
o The admission cost for the Museum
o The admission cost for the Train Ride
Let's make some equations.
x=number of people
Museum: 3x=total cost for Museum (m)
Train Ride: 5x=total cost for Train Ride (t)
m+t= total money spent
Now, let's replace the values.
Museum: 3(27)=$81
Train Ride: 5(27)=$135
$81+$135=$216 for the Train Ride and visit to the Museum.
Hope this helps!

Assume that when adults with smartphones are randomly selected, 49% use them in meetings or classes. If 30 adult smartphone users are randomly selected, find the probability that exactly 23 of them use their smartphones
Answer: 0.0013684
Step-by-step explanation:
Given the following :
Probability (p) = 49% = 0.49
Number of selected adults (n) = 30
Find the probability that exactly 23 use their smartphone.
The problem is abive can be solved using the binomial probability function.
Binomial probability :
P(X = x) = [n! / x! (n-x)!] * P^x * (1 - P)^(n-x)
At x = 23
P(X = 23) = [30! / 23! (30-23)!] * P^23 * (1-0.49)^(30-23)
P(X = 23) = [30! / 23! (7)!] * 0.49^23 * (0.51)^7
P(X =23) = (2035800) × 6.72203E−10
= 0.0013684

Explain how you can determine that the following system has one unique solution – without actually solving the system.
2x+y=4
2y=6-2x
Answer:
Step-by-step explanation:
Well, first you'd have to get the equations in slope-intercept form in order to make it easier for you to see it in the bigger picture. 2x+y=4 would be y= 2x-4, and the other equation would be y= x-3. If you were to solve it, there would be one solution since the y's cancel out. If you graphed it, there would be a point of intersection, unlike when the lines are parallel if there's 0 solutions or only one line's there if there's infinitely many solutions.

Answer:
[tex]\frac{p}{2} + $580[/tex]
Step-by-step explanation:
p = Penny's salary
Karen's salary = $580 more than half of p
We can use the fraction [tex]\frac{p}{2}[/tex] to represent half of p.
Since Karen's salary is $580 more, her salary is $580 + [tex]\frac{p}{2}[/tex] .

63', 64°, 82°, 49° and 58°
Answer: 44°
Step-by-step explanation:
The sum of the exterior angles of a polygon is 360°
If your polygon has six sides, the final angle will be:
= 360 - (63 + 64 + 82 + 49 + 58)
