The case 1 (a certificate of deposit (CD) ) will earn more interest.
What is simple interest?Simple interest is the interest amount for a particular principal amount of money at some rate of interest.
Simple Interest is calculated using the following formula: SI = P × R × T, where P = Principal, R = Rate of Interest, and T = Time period.
Given
Case 1:
Principal p = $500
Time t = 3 years
Rate of interest r = 2%
Based on the given conditions
Simple Interest = [tex]\frac{prt}{100}[/tex]
= [tex]\frac{500(2)(3)}{100}[/tex]
= $30
Case 2:
Principal p = $250
Time t = 2 years
Rate of interest r = 3%
Based on the given conditions
Simple Interest = [tex]\frac{prt}{100}[/tex]
= [tex]\frac{250(3)(2)}{100}[/tex]
= $15
The case 1 CD will earn more interest.

Kevin's Pie Shop sold 60 pies last month; 2/10 were apple pies and 4/10 were peach pies. How many pies were neither apple nor peach?
Answer: 4/10, or 40%, or 24
Step-by-step explanation: 2/10+4/10 is 6/10, which is 60-36, which is 24. This means the remaining 24 pies are neither apple or peach.
Number of pies that were neither apple nor peach = 24
What is fraction?Fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Given,
Total pies sold last month = 60
No. of apple pies = 2/10 of 60
= 2 × 60/10
= 12
No. of peach pies = 4/10 of 60
= 4 × 60/10
= 24
Pies that are neither apple nor peach pie
= Total pies - (No. of apple pies + No. of peach pies)
= 60 - (12 + 24)
= 60 - 36
= 24
Hence, 24 pies are neither apple nor peach.

x(2y-x)^2 + 2x^2 (x-2y)
Answer:
[tex]=x(2y-x)(2y-3x)[/tex]
Step-by-step explanation:
We want to factor the following expression:
[tex]x(2y-x)^2+2x^2(x-2y)[/tex]
First, notice that both of the terms have an x. Thus, let's factor out the x first:
[tex]=x((2y-x)^2+2x(x-2y))[/tex]
Now, notice the similarity between (2y-x) and (x-2y). If we multiply either of them by a negative, they will be the same.
Therefore, we can factor out a negative from (x-2y). This will give us:
[tex]=x((2y-x)^2+2x(-(2y-x))[/tex]
Since multiplication is commutative:
[tex]=x((2y-x)^2-2x(2y-x))[/tex]
Now, we can factor out the (2y-x):
[tex]=x(2y-x)((2y-x)-2x)[/tex]
And we can simplify this to get:
[tex]=x(2y-x)(2y-3x)[/tex]
Alternate Method:
Starting from here:
[tex]x((2y-x)^2+2x(x-2y))[/tex]
We can factor out a negative from the (2y-x)² term. This yields:
[tex]=x((-1(x-2y))^2+2x(x-2y))[/tex]
Since -1 squared is positive, we can simplify:
[tex]=x((x-2y)^2+2x(x-2y))[/tex]
Now, we can factor out the (x-2y):
[tex]=x(x-2y)((x-2y)+2x)[/tex]
Simplifying gives:
[tex]=x(x-2y)(3x-2y)[/tex]
While this looks different, they are exactly the same. If we factor out a negative from both the second and third term, we get:
[tex]=x(-(2y-x))(-(2y-3x))[/tex]
The negatives will cancel, leaving us with:
[tex]=x(2y-x)(2y-3x)[/tex]
This is exactly the same as what we acquired previously.
Therefore, both answers are correct.
What is the slope of the line that passes through the points (-10,8) and (-15,-7)
Answer:
3
Step-by-step explanation:
Use the formula y2-y1/x2-x1
Plug in the values (-7-8)/(-15-(-10))
-15/-5
3
Answer:
slope = m , m = rise / run rise = change in y run = change in x
Step-by-step explanation:
to find change in y just subtract the second y from the first , like thus,
P1=(-10,8) = (X1,Y1)
P2=(-15,-7) = (X2,Y2)
-7-8=-15= change in Y
to find the change in X just subtract the second x from the first, like thus,
-15-(-10) = -15+10 = 5
m= -15/5
m=-3
