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

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.
so basically you can just tell me where the boxes go and bam you get 20 points

You select a marble without looking and then put it back. If you do this 25 times, what is the best prediction possible for the number of times you will pick a marble that is not blue?
LOOK AT IMAGE
Answers
Answer:
15
Step-by-step explanation:
Green is 3/5 of the set.
3/5 of 25 is 15.
Answer:
15 times
Step-by-step explanation:
Assuming that you are picking the marbles without replacement, the probability of picking a marble that is not blue is 3/5. This is because there are 3 green marbles and 2 blue marbles in the bag, so out of 5 possible outcomes, 3 of them are not blue.
To find the best prediction for the number of times you will pick a marble that is not blue in 25 trials, you can multiply the probability by the number of trials. This gives you 3/5 x 25 = 15. So, the best prediction is that you will pick a marble that is not blue 15 times out of 25.

It takes 18 hours to fill a pool using 8 garden hoses. How long would it take to fill the same pool using 9 garden hoses?
Answers
We want to find how long will take for 9 garden hoses to fill the pool given that we know how long 8 of them need.
9 garden hoses will fill the pool in 16 hours.
Now, let's see how to solve the problem.
We know that for 8 gardener hoses, the pool is filled in 18 hours.
So, if every gardener hoses fill the pool at a rate R, we have the equation:
(8*R)*18 hours = 1 pool.
We can solve this for R:
R = (1 pool)/(8*18 hours).
Now, if we have 9 gardener hoses, we will have:
(9*R)*T = 1 pool.
Now we want to find the value of T.
We start by replacing the value of R that we found.
(9*(1 pool)/(8*18 hours))*T = 1 pool.
(1 pool/16 hours)*T = 1 pool.
T = (1 pool)/(1 pool/16 hours) = 16 hours.
Then we can conclude that 9 garden hoses will fill the pool in 16 hours.

Answers
Answer:
400,000 in sales
Step-by-step explanation:
50% of 10,000 is 5,000. 5,000x40=200,000
25% of 10,000 is 2,500. 2,500x30=75,000
25% of 10,000 is 2,500. 2,500x50=125,000
add 200,000+75,000+125,000=400,000 in sales

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answers
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143
The Smith family went to eat at Buffalo Wild Wings. The bill was $43.86. They gave the server a 20% tip. How much did they pay altogether?
Answers
$52.63
Step-by-step explanation:To find 20% of $43.86 we multiply $43.86 by 0.2
$43.86 • 0.2 = $8.772
Now add $43.86 and $8.772 to find out how much the family paid altogether.
$43.86 + $8.772 = $52.632
In money the smallest place value is cents so we have to round to the hundredths place.
Doing this we get the grand answer of:
$52.63
To find the altogether cost of the meal including tip you need to multiply the bill ($43.86) by 1.20
43.86(1.2) = 52.632
Same would go for if you were leaving a 10% tip but you would multiply by 1.10
