Answer:
[tex]y= 500(1+0.15)^x[/tex]
Step-by-step explanation:
This problem can be solved using concept of compound interest
In compound interest
if p is the principal amount
and r is the interest rate
then value of principal amount(A) after n years time is given by
A = p(1+r)^n
=>[tex]A = p(1+r)^n[/tex]
__________________________________
in the problem
in place of n we have x years
y is the amount which is the total amount after n years
p is the principal money deposited = $500
r = 15%
substituting these value in the formula for amount after n years we have
[tex]y= 500(1+15/100)^x\\y= 500(1+0.15)^x[/tex]
Thus, function modeling the situation is [tex]y= 500(1+0.15)^x[/tex]

The percentage of salad bars offered to customers in 1998 is; 70%.
What is the percentage?The percentage refers to the value of a variable contained in a whole number.
The percentage is the ratio that a variable is contained in another.
Percentages, which are over 100, are depicted using the percentage sign (%).
Data and Calculations:
We are Given that Of the markets in a certain city, 7/10 offered customers a salad bar in 1998 .
7/10 salad bars were offered to customers,
The conversion to percentage = 70% (7/10 x 100)
Thus, the percentage of salad bars offered to customers in 1998 would be equal to 70%.

Can anybody help me.
Answer:
1st one
Step-by-step explanation:
Work out the percentage change to 2 decimal places when a price of £189 is decreased to £150.
Answer:
The percentage change is -21%
Step-by-step explanation:
The percentage change can be expressed by the formula;
(new price -old price)/old price * 100%
New price = £150
old price = £189
Inputing these values in the formula, we have;
(150-189)/189 * 100%
-39/189 * 100%
= -20.63% and that is approximately -21%

A number cube labeled 1 through 6 is rolled. Find the probability that the cube lands on a number less than 5
Answer:
2/3
Step-by-step explanation:
The number cube has 6 faces labelled 1 - 6.
There are 4 numbers less than 5 (1, 2, 3, 4).
Therefore, the probability that the cube lands on a number less than 5 is:
4/6 = 2/3
what is the scale factor of polygon qrstu to poligon defgh
Answer:
A
Step-by-step explanation:
Since the two polygons are similar, corresponding sides will have a constant ratio. So, the ratio between ST and FG will be the same as the scale factor between the two shapes.
[tex]\dfrac{FG}{ST}=\dfrac{15}{36}=\dfrac{5}{12}[/tex]
Therefore, the correct answer is choice A. Hope this helps!

Answer:
w = -5x^2+20x+160/x
Step-by-step explanation:
Divide both sides by x and since you can't divide -5(x-8)(x+4) by x, it becomes a fraction resulting the answer to be w = -5x^2+20x+160/x.

17. Write an informal proof to show triangles ABC and DEF are similar.
IF YOU LOOK CLOSE YOU CAN SEE THE NUMBERS AND LETTERS FOR THE SHAPE,!!
The smaller triangle is DEF which has sides
DF = 1DE = 2EF = 3The larger triangle ABC has side lengths of
AC = 2AB = 4BC = 6Note how the sequence 2,4,6 is exactly double that of 1,2,3. Therefore, the sides of triangle ABC are twice as large as the corresponding sides of triangle DEF.
Put another way, computing the ratios of the corresponding sides all lead to the same value, so we have BC/EF = 6/3 = 2, and we have AB/DE = 4/2 = 2, and finally AC/DF = 2/1 = 2. These three equations all confirm ABC is twice as large as DEF.
By the SSS (side side side) similarity theorem, we can conclude the triangles are similar. They have the same shape, but different size.

y= -3x +1
Simplify your answer and write it as a proper fraction, improper fraction, or integer.
Answer:
-3
Step-by-step explanation:
if ay=bx+c , then the slope is b/a
I have 1*y=-3*x+1, the slope is -3/1=-3
Or
the slope is y2-y1/x2-x1
if x1=1 ,y1= -3*1+1=-3+1=-2
x2=2, y2=-3*2+1=-6+1=-5
the slope is (y2-y1)/(x2-x1)=(-5+2)/1=-3

20 points for who ever get it right someone who knows what they doing please
Answer:
F is greater than 25
F is positive
Step-by-step explanation:
You know that F must be positive, since a number is subtracted from it and then another number is multiplied by that difference. Since a positive number multiplied by a negative number is negative, F must be positive.
You also know that F is greater than 25, because a number is subtracted from it and it is multiplied by a fraction between 0 and 1, meaning that that difference is further reduced.
Hope this helps!

Letters w, x, y, and z are angle measures. Lines r and s are intersected by line m. At the intersection of lines m and r, clockwise from the top, the angles are w, x, blank, blank. At the intersection of lines m and x, clockwise from the top, the angles are: 92 degrees, y, z, blank. Which should equal 92° to prove that r ∥ s? w x y z
Answer: Angle w and angle z should equal 92° to prove that r║s
Step-by-step explanation: Let us start by constructing the lines r and s, and then draw a transversal to intersect both lines as stated in the question. At the intersection of lines m and r, we have clockwise from the top angles w, x and the other two blank. This is as shown in the picture attached.
Also at the intersection of lines m and s, clockwise from the top, the angles are 92, y, z and a blank. This is also clearly marked in the picture attached.
If the two lines r and s are parallel, then it means;
(1) Angle 92 is equal to angle z (opposite angles are equal)
(2) Angle z is equal to the blank underneath angle x (corresponding angles on two parallel lines are equal)
(3) Angle 92 is equal to the blank underneath angle x (alternate angles on two parallel lines are equal)
(4) Angle 92 is equal to angle w (corresponding angles on two parallel lines are equal)
Therefore, of all four angles marked as w, x, y and z angles w and z should equal 92° to prove that line r is parallel to line s.
