Michelle has money in two savings accounts. One rate is 6%
and the other is 14%
. If she has $900
$
900
more in the 14%
account and the total interest is $209
, how much is invested in each savings account?
Answer:
$415 at 6% and $1315 at 14%
Step-by-step explanation:
She has x amount at 6%.
She has y amount at 14%.
y = x + 900
0.06x + 0.14y = 209
Since the first equation is already solved for y, we use the substitution method. Substitute x + 900 for y in the second equation and solve for x.
0.06x + 0.14(x + 900) = 209
0.06x + 0.14x + 126 = 209
0.2x = 83
x = 415
y = x + 900
y = 415 + 900
y = 1315
Answer: $415 at 6% and $1315 at 14%

268 cm^2
Step-by-step explanation:
Pink prism:
top: 2 cm * 2 cm = 4 cm^2
right, left, back, front: 4 * 2 cm * 6 cm = 48 cm^2
bottom: completely covered in connection to green prism
Total surface area of pink: 52 cm^2
Green prism:
bottom: 10 cm * 5 cm = 50 cm^2
front, back: 2 * 10 cm * 4 cm = 80 cm^2
right, left: 2 * 5 cm * 4 cm = 40 cm^2
top: 10 cm * 5 cm - 2 cm * 2 cm = 46 cm^2
Total surface area of green: 216 cm^2
Total surface area of composite solid:
52 cm^2 + 216 cm^2 = 268 cm^2

Which of the following equations gives the
relationship between the price in dollars, p, and the
number of pieces of salt-water taffy, s, in a bag of salt-
water taffy from Walter's Watery Taffy?
Answer: p=0.25s
Step-by-step explanation: I am taking the test to
The correct equation is p = ms + b, where m and b are constants.
This equation represents a linear relationship between the price p and the number of pieces of salt-water taffy s. The constant m represents the slope of the line, and the constant b represents the y-intercept.
The other equations are not correct because they do not represent a linear relationship. For example, the equation p = [tex]s^2[/tex] represents a quadratic relationship, and the equation p = s/2 represents a linear relationship with a slope of 1/2.
Here is a brief explanation of why the correct equation is p = ms + b.
The price p is a linear function of the number of pieces of salt-water taffy s. This means that the price increases at a constant rate as the number of pieces of salt-water taffy increases.
The constant m represents the slope of the line. The slope of the line tells us how much the price increases for every additional piece of salt-water taffy.
The constant b represents the y-intercept. The y-intercept tells us the price when the number of pieces of salt-water taffy is 0.
Therefore, the correct equation is p = ms + b.

f = faces she paint = 25 faces
M = 2.50(f) + 12 —> ? = 2.50(25) + 12 = 74.5
HELPPP THIS IS SO HARD Keegan and Jeff did some research and found that there are approximately 7,492,000,000,000,000,000 grains of sand on Earth. Jeff says that it is about 7 × 10(15) grains of sand. Keegan says that this is about 7 × 10(18) grains of sand.
Guys please add the step by step so they dont know im cheating
Answer:
Keegan is correct.
Step-by-step explanation:
Keegan is correct.
Put a decimal point after the first digit which is 7. Count decimal places there are after the 7, this will be your power of 10. There are 18 decimal places after the 7. This means the answer would be 7 x 10^18.
Basically, Keegan is right
when you present 7,492,000,000,000,000,000 in standard form, it is indeed, 7×10¹⁸, the reason Jeff is wrong is because he only counted Os and not the numbers 492 which Keegan rounded to Os. Ok, to simply this 7×10¹⁵ equals 7 000 000 000 000 000, and 7×10¹⁸ is 7 000 000 000 000 000 000 while is closer to thee original answer than Jeff's response.

Consider the following game. The diamonds are taken out of a deck of cards, and are shuffled randomly. You pay $5 to pick one of the diamonds. If you pick the ace of diamonds, you win $20. If you pick the jack, queen, or king, you win $10. However, if you pick any other card, then you don't win any money. What is the expected value of this game? Is it in the player's favor to play this game? Why or why not?
Answer:
It is not in the players favor because there is a 4/13 chance that the player will win money. That"s not even 50%. So its up to the player if they want to take that risk but its a 0.3% chance that the player will win money.
