3. Ellen has 3 times as many CD's as Sammy. Together they have 32 CD's. How many does
each person have?
Answer:
8
Step-by-step explanation:
sammy has 8 and ellen has 24 then add sammy's 8
24+8=32
Final answer:
By setting up a system of equations, we find that Sammy has 8 CD's and Ellen has 24 CD's.
Explanation:
The student's question involves solving a system of equations to determine how many CD's each person has.
Let's define Ellen's number of CD's as E, and Sammy's number of CD's as S.
According to the question, Ellen has 3 times as many CD's as Sammy, so we can write this as
E = 3S.
We also know that together they have 32 CD's, which can be written as
E + S = 32.
By substituting the first equation into the second, we get
3S + S = 32
4S = 32.
Dividing both sides by 4 gives us
S = 8.
Therefore, Sammy has 8 CD's.
To find out how many CD's Ellen has, we substitute S back into the first equation:
E = 3 * 8
E = 24.
So Ellen has 24 CD's.
A scuba diver dives down 20 feet into the ocean. He then swims 11 feet back up towards the surface. What is the position of the scuba diver relative to the surface?
The position of the diver relative to the surface is -9 feets
Using the parameters given for our Calculation;
downward distance = 20Upward distance= 11Difference in distance
20 - 11 = 9Since, we are expressing position relative to the surface , The diver is 9 feets below the surface , which would be expressed as -9 feets.

Two right triangles are graphed on a coordinate plane. One triangle has a vertical side of 2 and a horizontal side of 6. The other triangle has a vertical side of 10 and a horizontal side of 30.
Could the hypotenuses of these two triangles lie along the same line?
(A) No, because they are not similar triangles
(B) No, because one is larger than the other
(C) Yes, because they are both right triangles
(D) Yes, because they are similar triangles
Answer:
Consider two right triangles: 1. ΔABC with vertices A(0,0), B(0,2), C(6,0). Then AB is perpendicular to AC and AB=2 units (vertical leg), AC=6 units (horizontal leg).2.

help! i need the answer to this
Answer:
Yes
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 270°
a point (x, y ) → (y, - x )
Thus
A(1, 1 ) → A'(1, - 1 )
B(1, 4 ) → B'(4, - 1 )
C(3, 4 ) → C'(4, - 3 )
D(6, 1 ) → D'(1, - 6 )
These are the correct coordinates for the diagram A'B'C'D'
A translation (x, y ) → (x + 4, y + 1 )
Add 4 to the x- coordinates and add 1 to the y- coordinates, that is
A'(1, - 1 ) → A''(1 + 4, - 1 + 1 ) → A''(5, 0 )
B'(4, - 1 ) → B''(4 + 4, - 1 + 1 ) → B''(8, 0 )
C'(4, - 3 ) → C''(4 + 4, - 3 + 1 ) → C''(8, - 2 )
D'(1, - 6 ) → D''(1 + 4, - 6 + 1 ) → D''(5, - 5 )
These are the correct coordinates for the diagram A''B''C''D''

At King’s Super Market, Clay bought 214 pounds of tomatoes for $13.50. Gabriella bought 112 pounds of tomatoes for $6.75 at the local farmer’s market. Who got the better deal?
At King’s Super Market, Clay bought 214 pounds of tomatoes for $13.50. Gabriella bought 112 pounds of tomatoes for $6.75 at the local farmer’s market. Who got the better deal?
Gabriella got the better deal, as she paid slightly less per pound for the tomatoes.
To determine who got the better deal, we need to calculate the price per pound of tomatoes for each person.
For Clay:
Price per pound = Total price / Total pounds
Price per pound = $13.50 / 214 pounds ≈ $0.0631 per pound
For Gabriella:
Price per pound = Total price / Total pounds
Price per pound = $6.75 / 112 pounds ≈ $0.0607 per pound
Comparing the two, we see that Gabriella paid approximately $0.0607 per pound, while Clay paid approximately $0.0631 per pound.

kara borrowed $3650 for one year at an annual interest rate of 16% how much did kara pay in interest show work
Kara will pay $584 in interest for a loan of $3650 at an annual interest rate of 16% after one year, calculated using the simple interest formula I = PRT.
Explanation:To calculate the amount of interest Kara pays on a loan of $3650 at an annual interest rate of 16%, we use the formula for simple interest, which is:
I = PRT
Where:
I is the interestP is the principal amount (the initial amount of the loan)R is the annual interest rate (in decimal form)T is the time the money is borrowed for, in yearsUsing the values given:
P = $3650R = 16% or 0.16 (as a decimal)T = 1 yearWe calculate the interest Kara will pay:
I = 3650 * 0.16 * 1
I = $584
Therefore, Kara will pay $584 in interest after one year.

Find the interest earned on a $30,000 deposit for 6 months at 12% interest.
compounded continuously.
Answer:
3,600
Step-by-step explanation:
First you have to know that 12% is the same as .12 Since you have 12%interest you would multiply 30,000 × .12 When you do you get 3,600. This is your interest. You could also do it another way. You could take 30,000 and divide it by the 6 months. You get 5,000. Now you would take this number and multiply it by .12(the 12%) and get 600. This is interest per month. Since you have 6 months you multiply 600×6. You end up with 3,600.
3.249 rounded to nearest tenth
The number 3.249 rounded to nearest tenth is; 3.2
According to the question;
We are required to round off the number 3.249 to nearest tenthAccording to the place value concept in mathematics; the place values after the decimal point in a decimal number are identified from left to right, as tenths, hundredths, thousandths etc.
Evidently, the number which occupies the tenths position in 3.249 is the digit 2.
Consequently, to round the number 3.249 to the nearest tenth; the digit 4 is considered and rounded off to 0 or 1 as the case may be.Since, 4 is less than 5, it is rounded off to 0 and added to the digit, 2 which occupies the tenths position in the number 3.249
Ultimately, the number 3.249 rounded to nearest tenth is 3.2.
