Original price: $1,050.00
Increase by 0.5%
Final price: x
Proportional constant:
Answer:
Final price = $1,055.25
Step-by-step explanation:
Given:
Original price = $1,050
Rate of increase = 0.5%
Find:
Final price
Computation:
Final price = Original price + [Original price x Rate of increase]
Final price = 1,050 + [1,050 x 0.5%]
Final price = 1,050 + 5.25
Final price = $1,055.25

The price of XYZ stock fluctuates widely. In January it closed at $3.50 but In February it Closed at $2.25. However at the end of March it shot back up to $5.00.
What was the average monthy change in the price of XYZ stock from january through march?
Answer:
$3.583
Step-by-step explanation:
Given the monthly stock prices :
January = $3.50
February = $2.25
March = $5.00
The average monthly change in price of XYZ stock from. JANUARY through MARCH is;
(January + February + March) / 3
Average monthly change :
(3.50 + 2.25 + 5.00) / 3
$10.75 / 3
= $3.583
A student usually saves $20 a month. He would like to reach a goal of saving $350 in 12 months. The student writes the equation
350 = 12(x + 20) to represent this situation. Solve the equation for x.
• Show your work or explain your answer.
Write your answer as a sentence that describes what the variable x represents.
Answer:
Step-by-step explanation:
350=12(x+20)
(divide both sides by 12)
29.1667=x+20
(subtract 20 from both sides)
x=9.16667
X (9.17) is the additional amount of money the student must save each month in order to reach his goal.

Answer:
d. 340
Step-by-step explanation:
4 x 4 = 16
4 x 4 = 16
11 x 24 = 264
11 x 4 = 44
16 + 16 + 264 + 44 = 340
the gradiant y=2x³-5x+1 at point (2,7)
Given:
The equation of the curve is:
[tex]y=2x^3-5x+1[/tex]
To find:
The gradient (slope) of the given curve at point (2,7).
Solution:
We have,
[tex]y=2x^3-5x+1[/tex]
Differentiate the given equation with respect to x.
[tex]y=2(3x^2)-5(1)+(0)[/tex]
[tex]y'=6x^2-5[/tex]
Now we need to find the value of this derivative at (2,7).
[tex]y'_{(2,7)}=6(2)^2-5[/tex]
[tex]y'_{(2,7)}=6(4)-5[/tex]
[tex]y'_{(2,7)}=24-5[/tex]
[tex]y'_{(2,7)}=19[/tex]
Therefore, the gradient (slope) of the given curve at point (2,7) is 19.

Step-by-step explanation:
Which improper fraction is represented by the shaded
area?
Answer:
11/8
Step-by-step explanation:
If we look at each bar, we can see that it is split into 8 pieces.
This means our improper fraction will be over 8.
Now, we want to count the red blocks.
There are 11.
This means that our fraction is 11/8.
Hope this helps!
Answer:
11/8
Step-by-step explanation:
Firstly, one whole piece is shaded so that is 1.
Then, the other piece is 3/8.
The mixed number would be 1 3/8.
Now convert this to a improper fraction.
Multiply the denominator and the whole number. 1 * 8 = 8
Then the product of that, add that to the numerator, 8 + 3 = 11
So you get 11. That would be the numerator of the improper fraction. The denomintaor stays the same.
So you would get, 11/8

Nick is making bread.
He needs 103 cups of flour to make one whole loaf of bread.
He has 53 cups of flour.
Use the drop-down menus to complete the statements below about the bread that Nick can make.
Answer:
Well, I can't see the drop-down options but with that amount of flour, I suppose he could make one half of a loaf but he can't make an entire loaf.
Edit:
The answers for the drop-down options:
1.) Nick can make less than one whole loaf of bread.
2.) Nick can make exactly 1/2 loaf of bread with the flour he has.

Answer:
- 7 < - 5
Step-by-step explanation:
Because negative 7 is technically lower than negative 5. Due to them being negative the more closer you are to -1 the more higher of a number it is. I don't know how to explain it but I hope that it makes sense!

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 8 N acts on a certain object, the accelerstion of the object is 4 m/s2. If the acceleration of the object becomes 9 m/s?, what is the force?
8N = 4m/s^2
2N = 1m/s^2
18N = 9m/s^2

9514 1404 393
Answer:
136
Step-by-step explanation:
The attached chart shows the result of using the numbers in the problem statement to calculate the percentage of the population in each category.
95% accuracy on infected individuals is assumed to mean that 95% of the 2% who are infected return a positive test result. The other 5% return a negative test result.
Similarly, 90% accuracy on uninfected individuals is assumed to mean that 90% of the 98% who are not infected will return a negative test result, and the remaining 10% of those 98% will return a (false) positive test result.
Then of the 11.7% who return a positive test result, only 1.9% are actually infected. This fraction is a/b = 19/117, so ...
a + b = 19 + 117 = 136
_____
Additional comment
When forming ratios of percentages, one must be very clear about the base of the percentage. Above, the base for every percentage is the entire population of mathletes. The fraction 19/117 is the fraction of those who tested positive that are actually infected (about 16.2% of positives).

the answer is 136

Hi please help me with this asap.
I need help with Algebra 2. Thank you! :)
Answer:
B: 6.0
Step-by-step explanation:
-3t^2+9t+54 = 0
This is the equation that needs to be solved
Divide both sides by -3
t^2 - 3t - 18 = 0
The factors of 18 are: (1 18) (2 9) (3 6)
3 - 6 = -3 and 3 x -6 = -18
So: (t + 3) (t - 6) = 0
t = -3, 6
It can't be negative so the answer is 6
