that compounds interest weekly. Use the TVM solver on your calculator to find the future
value of the account after nine years,
Answer:
16,507.38
Step-by-step explanation:
The equation for this would be 8600(1 + 0725/52)^52*9
9 is the years, 52 is the compounded weekly, and 8600 is the initial amount.
Solving the equation, we get:

Clothes company produce suites the variable cost to make each one is $20 each and sells them for $30 each. The cost to rent for the factory is $400. How many suits the company should sell to break-even point?
Answer:
Break-even point in units= 40
Step-by-step explanation:
Giving the following information:
Unitary variable cost= $20
Selling price per unit= $30
Fxed costs= $400
To calculate the break-even point in units, we need to use the following formula:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 400 / (30 - 20)
Break-even point in units= 40

B)
Factor out the greatest common factor.
C)
Factor out the greatest common factor; then factor

D)
Factor out the greatest common factor; then factor

Answer: C
Step-by-step explanation:
Determine the common ratio and find the next three terms of the geometric sequence. 8, -20, 50, ... a. -2.5; -125, 312.5, -781.25 c. 2.5; -125, 312.5, -781.25 b. -2.5; -70, 240.6, -642.85 d. 2.5; -70, 240.6, -642.85
Answer:
The common ratio is -2.5
The next three terms are;
-125, 312.5 and -781.25
Step-by-step explanation:
Here, firstly we want to determine the common ratio
To
do this, we have to divide the succeeding term by the preceding term
We have this as;
50/-20 = -20/8 = -2.5
Now, to get the next terms,
we multiply the given last term by the common ratio
That will be;
50 * -2.5 = -125
next is to multiply this by the common ratio
That will be;
-125 * -2.5 = 312.5
And lastly, we have
312.5 * -2.5 = -781.25

Answer:
The correct answer is C
Step-by-step explanation:
Helpful fact- All triangles are 180 degrees
Angle 1 = 31 degrees
Angle 2= 71 degrees
X= Angle 3
Y = Angle 1&2 Sum
So by adding Angles 1 & 2 we get a sum to subtract from 180 and get a difference. That difference will be Angle 3.
Angle 1 + Angle 2 = Y
180 - Y= X
31 + 71 = 102 degrees Y= 102 degrees
180 - 102 = 78 degrees X= 78 degrees

what is the median of 82, 4, 94, 4, 60, 91
And what is the mode and range
Answer:
The median is 55.833
The range is 90
The mode is 4
Step-by-step explanation:
To find median you
1. Arrange your numbers in numerical order.
2. Count how many numbers you have.
3. If you have an odd number, divide by 2 and round up to get the position of the median number.
4.If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.
To find mode you put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode. To find range you first put all the numbers in order. Then subtract (take away) the lowest number from the highest. The answer gives you the range of the list.

People use water to cook, clean, and drink every day. An estimate of 15.5% of the water used each
day is for cooking. If a family uses 68.2 gallons of water a day for cooking, how many gallons do they use every day?
Answer:
260 gallons
Step-by-step explanation:
An estimate of 26.5% of the water used each day is for cleaning and a family uses 68.9 gallons of water a day for cleaning,
Percentage of water used for cleaning= 26.5%
Gallons of water used for cleaning= 68.9
Let the number of gallons used everyday be represented by g. This will give:
26.5% of g = 68.9
26.5/100 × g = 68.9
0.265 × g = 68.9
0.265g = 68.9
Divide both side by 0.265
0.265g/0.265 = 68.9/0.265
g= 260
260 gallons of water are used everyday
Lightning strikes the earth more than 60 times per second. How many times would it strike in 3 minutes 15 seconds
Answer: 11,700 times
Step-by-step explanation:
First find the number of seconds in 3 minutes 15 seconds.
Each minute is 60 seconds so 3 minutes would be:
= 3 * 60
= 180
Add the 15:
= 195 seconds
Lightning strikes more than 60 times per second so we shall use 60 times
= 60 * 195
= 11,700 times
Chris tosses two number cubes labeled 1 to 6. What is the probability of rolling
double 4s?
Answer:
1/36
Step-by-step explananation:
The probability of rolling a 4 on one cube is 1/6. Any following throws are completely independent, so if we want the probability of rolling
double 4s, we multiply 1/6 by 1/6, obtaining 1/36.
The probability of rolling double 4s is 1/36.

From 10:00 am to noon, the rise in temperature is 4 degrees C, and from 3:00 pm to 5:00 pm, the fall in temperature is 6 degrees C. What is the average rate of: a) The rise in temperature per hour? b) The fall in temperature per hour?
Answer:
(a) 2 degree celsius per hour
(b) 3 degree celsius per hour.
Step-by-step explanation:
From the question,
(a) Avearge rate of rise in temperature per hour(T') = Rise in temperature(T)/Time required for the rise(t).
T' = T/t.................... Euqation 1
Rise in temperature (T) = 4 degree celsius, t = 10.00 am to noon = 2 hours.
Substitute into equation 1
T' = 4/2
T' = 2 degree celsius per hour.
(b) Also,
Average rate of fall in temperature per hour (T') = Fall in temperature (T)/Time(t)
T' = T/t
Given: T = 6 degree celsius, t = 3:00 pm to 5:00 pm = 2 hours
T' = 6/2
T' = 3 degree celsius per hour
Solve, using the substitution method.

• (-6, -5)
•(15,-4)
• (6, 1)
• (-10, -1)
Answer:
(-6,-5)
Step-by-step explanation:
X+y=-11
solve for x
x=-11-y
substiute x value into 2nd equation
2x-3y=3
2(-11-y)-3y=3
-22-2y-3y=3
-5y=25
y=-5
substitute -5 for y in either equation to find x
x+y=-11
x+-5=-11
x=-6
