Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Answers
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500
$4500
$4500
$4500

Remember to find the are and use 3.14 for the value of pi and please round the answer to the nearest tenth.
Answers
A=3.14(10)^2
A=314cm
Since the radius is 10, you multiple 10 by 10 (hence the second power) and you’d get 100.
Now multiplying 100 by pi, (3.14) you get 314
Your answer is 314.

these are the answers
1.2 x 103 lbs.
1.19 x 103 lbs.
11 x 102 lbs.
5.8 x 102 lb
Answers
Answer: Option A is the correct answer
Step-by-step explanation: I took the test and got it right
The total weight of the two animals is 1.19 x 10³ lbs. So the correct option is B.
Given approximate weights of the two animals are as:
1. 5.12 x 10² lbs
2. 6.8 x 10² lbs
We need to find the total weight of the two animals.
Step 1: Add the weights together:
5.12 x 10² lbs + 6.8 x 10² lbs
Step 2: Perform the addition:
(5.12 + 6.8) x 10² lbs
11.92 x 10² lbs
Step 3: Express the result in scientific notation with the correct number of significant digits:
The first number, 11.92, has three significant digits. To maintain three significant digits in the final answer, we can express it as 11.9 (rounding to the nearest tenth) and adjust the exponent accordingly:
11.9 x 10² lbs
This matches option 2 from your provided answers:
2. 1.19 x 10³ lbs.
So, the correct answer is: 1.19 x 10³ lbs.

Which fractions have a LCD of 30? A. 3/4 1/7 16 B.2/3 1/5 1/15 C. 2/15 1/4 1/3 D. 2/3 1/5 1/6
Answers
Answer:
1/5, 1/6 and 1/15
Step-by-step explanation:
Multiples of 15 are 30, 45, 60, 75, 90. Now, when you look at the list of multiples, you can see that 30 is the smallest number that appears in each list. Therefore, the least common denominator of 1/5, 1/6, and 1/15 is 30.
The fractions with LCD of 30 are D. 2/3, 1/5 and 1/6.
What is LCD?LCD, which is the abbreviated form for Least Common Denominator, is the lowest of all the common multiples of the denominators for a set of fractions.
We need to find the set of fractions with LCD as 30.
A. 3/4, 1/7 and 1/6
The denominators are 4, 7 and 6.
30 is not a multiple of 4 as well as 7.
So this set is not the answer.
B. 2/3, 1/5 and 1/15
Denominators : 3 and 5
Multiple of 3 = 3, 6, 9, 12, 15, ......
Multiples of 5 = 5, 10, 15, ......
Multiples of 15 = 15, 30, .....
15 is the LCD.
C. 2/15, 1/4 and 1/3
Denominators = 15, 4 and 3
Again 30 is not a multiple of 4.
D. 2/3, 1/5 and 1/6
Denominators = 3, 5 and 6
Multiples of 3 = 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, .......
Multiples of 5 = 5, 10, 15, 20, 25, 30, ......
Multiples of 6 = 6, 12, 18, 24, 30, .......
LCD of three fractions = 30
Hence the set of fraction is D. 2/3, 1/5 and 1/6 has LCD equals 30.
