Answer:
1200 miles
Step-by-step explanation:
Miss Turner drove 900 miles in March.
We are told that she drove 3 times as many miles in March as she did in January. This means that to get the number of miles she drove in January, we divide the number of miles she drove in March by 3:
900 / 3 = 300 miles
We are also told that she drove 4 times as many miles in February than January. This means that to get the number of miles she drove in February, we multiply the number of miles she drove in January by 4:
300 * 4 = 1200 miles.
Hence, she drove 1200 miles in February.

Answer:
$9627.46
Step-by-step explanation:
-The amount after 19 years for a 6.5% compounded continuously is given by the formula:
[tex]A=Pe^{rt}[/tex]
Where:
A is the final amount after investment
P is the initial amount invested
r is the stated annual interest rate.
t is period of investment
#We then substitute our values in the equation to solve for A:
[tex]A=Pe^{rt}\\\\=2800e^{19\times 0.065}\\\\=9627.46[/tex]
Hence, the amount after 19 years is $9,627.46
Nasim is making hot sauce. She puts in chile peppers and tomatoes in a ratio of 1 to 3. If she puts in 9 tomatoes, how many chile peppers should she put in?
Answer: 3
Step-by-step explanation:
Nasim is making hot sauce. Nasim puts in chile peppers and tomatoes in a ratio of 1 to 3.
Assuming Nasim puts in 9 tomatoes, the number of chile peppers should she put will be:
Ratio of chile peepers to tomato= 1;3
Since she put 9 tomatoes, chile peppers= (1×9)/3 = 9/3 = 3.
For 1 chile peeper, there'll be 3 tomatoes.
For 3 chile pepper, thee will be 9 tomatoes.
Answer: She needs to add 3 chile peppers.
Step-by-step explanation:
The ratio of chile peppers to tomatoes is 1:3
this means that for each 3 tomatoes, she puts one chile pepper.
Then if she puts 9 tomatoes, this means that she puts 3 tomatoes 3 times.
And we know that for each 3 tomatoes she needs to add 1 chile pepper, then she needs to add 1 chile pepper 3 times:
3*1 = 3 chile peppers.
She needs to add 3 chile peppers.
As of a certain date, 94,696 of the four-character sequences using either letters or digits had not yet been claimed. If a four-character name is randomly selected on that date, what is the probability that it is already owned? (Round your answer to four decimal places.)
Answer:
Hence the probability that are already owned are 0.943620
Step-by-step explanation:
Given:
No fo character sequences using either letter or digits had not been claimed=94696
To find :
What is probability that letter are already claimed ?
Solution:
We know that there are 26 alphabets and digits are 0,1,2.. 9
Hence total will be of 36.
Now we are going to Arrange the sequence for all possible values
as there 4 characters we get ,each of them with 36 possible values
=36*36*36*36
=36^4
=1679616.
Now we have a sequence with 94696 character and digits are not claimed .
Its probability
=94696/1679616
=0.05637.
So the required probability will be ,
P(claimed)=1- P(Not claimed)
= 1-0.056379
=0.943620
Hence the probability that are already owned are 0.943620

Suppose that $6500 is placed in an account that pays 3% interest compound each year. Assume that no withdrawals are made from the account
Find the amount in the account at the end of 1 year
Find the amount in the account at the end of 2 years
Answer:
1 year:
The amount is $6695 and the interest is $195
2 years:
The amount is $6895.85 and the interest is $395.85.
The balance in the account at the end of 1 year would be approximately $6695 and at the end of 2 years would be approximately $6899.85 with an initial investment of $6500 with a 3% interest rate compounded annually.
Explanation:The subject of this question is compound interest. When an amount of money is placed in an account with a certain interest rate, the amount grows over time. In this case, the initial investment is $6500 and the interest is compounded annually at a rate of 3%.
To calculate the total amount in the account after a certain period, you can use the following formula:
A = P(1 + r/n)^(nt)
A is the amount of money accumulated after n years, including interest. P is the principal amount (the initial amount), r is the annual interest rate (in decimal), n is the number of times that interest is compounded per year, and t is the time in years.
Applying this formula to the problem: for the end of first year, t=1, we will have:
A=6500(1 + 0.03/1)^(1*1) ≈ $6695
For the end of 2 years, t=2, we will get:
A=6500(1 + 0.03/1)^(1*2) ≈ $6899.85
Therefore, the balance in the account at the end of 1 year would be approximately $6695 and at the end of 2 years would be approximately $6899.85. Assume there are no withdrawals from the account during this period.

Mimi opened a savings account 6 years ago. The account earns 1% interest, compounded monthly. If the current balance is $1,000.00, how much did she deposit initially?
Round your answer to the nearest cent.
Answer: the initial amount is $941.6
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1 + r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
A = $1000
r = 1% = 1/100 = 0.01
n = 12 because it was compounded 12 times in a year.
t = 6 years
Therefore,.
1000 = P(1 + 0.01/12)^12 × 6
1000 = P(1 + 0.00083)^72
1000 = P(1.00083)^72
1000 = 1.062P
P = 1000/1.062
P = $941.6
Chase halls health insurance cost $373.50 per month he must pay 25% of the amount and his employer pay 75% of the amount how much does mr hall pay for health insurance each month
Answer:
$93.38
Step-by-step explanation:
To solve this, we simply multiple $373.50 by 25% to figure out how much Mr.Hall pays for health insurance each month. Don't forget that we need to change 25% to its decimal form (25% -> 0.25).

Round answer to the nearest hundredth if necessary. If YV= 28in, find the length of VYX
Answer:
282°
Step-by-step explanation:
VYX = 360° - (YW + 15°)YW = 180° - 117° = 63°VYX = 360° - (63° + 15°) = 360° - 78° = 282°To find the length of VYX, use the Pythagorean theorem and set up an equation to solve for the length by squaring the lengths of the other sides and adding them together. Then, take the square root of the sum to find the length of VYX.
Explanation:To find the length of VYX, we can use the Pythagorean theorem. In a right triangle, the square of the hypotenuse (VYX) is equal to the sum of the squares of the other two sides (VY and YX). Since we know VY (28 inches), we can solve for the length of VYX
Using the Pythagorean theorem: (VYX)2 = (VY)2 + (YX)2
Plugging in the values: (VYX)2 = (28)2 + (YX)2
Since the question asks for the length of VYX, we can take the square root of both sides to find the length of VYX: VYX = √[(28)2 + (YX)2]

Mitchell received a stipend at the beginning of the semester to buy textbooks. During the semester, he spent $429.17 on textbooks. He had $77.85 of the stipend left at the end of the semester How much was Mitchell's stipend? A. $584.87 B. $351.32 C. $390.25 D. $507.02
Final answer:
(Option D)Mitchell's stipend was $506.02.
Explanation:
To find out how much Mitchell's stipend was, we can subtract the amount he spent on textbooks from the amount he had left at the end of the semester.
Let's assume Mitchell's stipend was X dollars.
He spent $429.17 on textbooks, so the remaining amount would be X - $429.17.
We know that he had $77.85 left, so we can set up the equation:
X - $429.17 = $77.85
Now, we can solve for X:
X = $77.85 + $429.17 = $506.02
So, Mitchell's stipend was $506.02. This corresponds to answer (Option D).
Find the value of 4x^2– 2y when x = 3 and y = 2.
Answer:
The answer is 32.
Step-by-step explanation:
Remember that order of operation is very important in this problem.
Substitute x for 3 and y for 2 in the equation.
When solving the first term, we must note that we have to square the 3 first before we multiply it by 4. So, 4(3)^2 is basically 36. To simplify the second term you just have to do 2*2, which is 4. 36-4=32, which is the answer.
Final answer:
The value of the expression 4x² - 2y when x = 3 and y = 2 is 32, found by substituting the values of x and y into the expression and simplifying.
Explanation:
To find the value of 4x² - 2y when x = 3 and y = 2, we need to substitute these values into the expression.
Start by substituting x with 3: 4(3)² = 4(9) = 36.Next, substitute y with 2: -2(2) = -4.Now, combine these results: 36 - 4 = 32.So, the value of the expression 4x² - 2y when x = 3 and y = 2 is 32.
Tim and Cynthia leave Cynthia's house at the same time. Tim drives north and Cynthia drives west. Tim's average speed is 10 mph slower than Cynthia's. At the end of one hour, they are 70 miles apart. Find Cynthia's average speed. (Round your answer to the nearest tenth.)
Answer:
54.2 mph
Step-by-step explanation:
Since the drivers leave at the same time and travel in directions 90° from each other, their separation speed can be found using the Pythagorean theorem. Let c represent Cynthia's average speed. Then (c-10) will represent Tim's average speed. Their combined separation speed is 70 miles per hour, so we can write ...
70² = c² +(c -10)²
4900 = 2c² -20c +100 . . . . eliminate parentheses
c² -10c -2400 = 0 . . . . . . . . divide by 2; put in standard form
(c -5)² -2425 = 0 . . . . . . . . . rearrange to vertex form
c = 5 ±5√97 . . . . . . . . . . . . solve for c, simplify radical
c ≈ 54.244 ≈ 54.2 . . . . . . . use the positive solution
Cynthia's average speed was 54.2 miles per hour.

Answer:
The average weight of okapi is 290 kg
The average weight of llama is 160 kg
Step-by-step explanation:
To solve the question, we are to resolve the word problem as follows;
Let the average weight of Okapi be X
The average weight of llamas be Y
X + Y = 450 and
3 Y = X + 190
Solving the above simultaneous equation, we have
X = 450 - Y
∴ 3·Y = 450-Y+190
4·Y =640
Y = 160 and X = 450 - 160 = 290
Therefore, the average weight of okapi = 290 kg while the average weight of llama = 160 kg.
