[tex]\text{ \$278.75}[/tex]EXPLANATION
We have that Sammi has $125.75 in her account and deposits (adds) $25.50 every month for 6 months.
To find how much is there after 6 months, first, find out how much she added to the account and then add that to the initial amount that was there.
After 6 months she deposited:
[tex]\begin{gathered} 6\cdot25.50 \\ \text{ \$153} \end{gathered}[/tex]Now, add that to the initial amount there:
[tex]\begin{gathered} 125.75+153 \\ \text{ \$278.75} \end{gathered}[/tex]That is the amount in the account at the end of 6 months.
Hello, is it possible to help me understand this question a little better?
1) Since the degree of the denominator is lower than the numerator's we can divide these expressions through long division that way:
As we can see in each step the aim is to cancel the leading coefficient.
2) Note that a Long Division, has a way to write its answer so we can tell that this is the answer:
[tex]\frac{3x^3-4x^2+5x-2}{3x+2}=\quad x^2-2x+3-\frac{8}{3x+2}[/tex]Note that the remainder is written above the divisor on the final answer.

What is the value of x?
SOLUTION
The principle behind the Exterior Angle Theorem is that:
the sum of two interior angles is equal to one exterior angle.
In this question, we have that :
X + ( X - 48 ) = X + 50
Collecting like terms, we have that:
2 X - 48 = X + 50
2X - X = 50 + 48
X = 98 Degrees.
CONCLUSION: The value of X = 98 Degrees.
if you walk 200 meters in 1 minute, 400 meters in 4 minutes and 800 meters in 10 minutes find your average velocity for the whole walk

Okay, here we have this:
Considering the provided figure and information, we are going to calculate the requested measure, so we obtain the following:
So to calculate the length of the base, we will solve in the formula for the area of the triangle, we have:
Triangle Area=(Base*height)/2
Triangle Area*2=Base*height
Base=(Triangle Area*2)/height
Let's replace:
[tex]\begin{gathered} Base=(24.75cm^2\cdot2)\frac{\placeholder{⬚}}{5.5cm} \\ =\frac{49.5cm^2}{5.5cm} \\ =9cm \end{gathered}[/tex]Finally we obtain that the length of the base of triangle is 9 cm.

What are the domain and range of the function f(x)=2x+1?domain: (0.00)range: (-0.00domain: (-0.00)range: (0.co)domain: (-0.00)range: (2.00)domain: (0.00)range: (2.0)
The given function is expressed as
f(x) = 2^(x + 1)
The domain of a function is the set of all the possible values of x that would satisfy the function.
The range of a function is the set of all the possible values of y that would satisfy the function.
Since the fuction has no denominator or even root, the values of can be all real numbers. This means that the domain would be between - infinity and infinity
For the range, no matter how small the value of x that we input into the function, the value of f(x) or y would never be lesser than zero. Also, there is no limit to the value of f(x) even if we input very large values of x. Thus, the range is between 0 and infinity. Thus,
the correct option is the second one

[tex]\begin{gathered} a)\text{ 23 \%} \\ b)\text{ w\lparen t\rparen= 90e}^{0.23t} \end{gathered}[/tex]Explanation:
a)We have the general representation as follows:
[tex]w(t)\text{ = ae}^{kt}[/tex]when t = 3, we have the value doubling
Thus: w(t) = 2 * 90 thousand = 180 thousand megawatts
Thus:
[tex]\begin{gathered} 180\text{ = 90e}^{3k} \\ e^{3k}\text{ = 2} \\ k\text{ = }\frac{ln\text{ 2}}{3}\text{ = 0.231} \end{gathered}[/tex]This means we have the continuous growth rate at 23%

Rewrite the expression using the distributed Property and for the final answer cant have Double signs/operations
Distributive Property
The distributive property of the product with respect to the sum states that if a product and a sum are to be operated like follows:
x* ( y + z )
Then the result is the product of x by each term separately:
x* ( y + z ) = x*y + x*z
Now, we have the expression:
8 ( 2m + 1 )
Applying the distributive property:
8 * 2m + 8 * 1
16m + 8

Two-thirds of the people on a hike are adults. If there are 36 adults, what isthe total number of people on the hike?
You have the following information:
- Two-thirds (which means 2/3) of the people on a hike are adults.
- There are 36 adults
In order to calculate the number of people, you consider that 36 is 2/3 of the total people. If you name x as the total people, the number of adults is 2/3x. Thus, you can write the following algebriac expression:
2/3 x = 36
you solve the previoues equation for x. First, you multiply both sides by 3 and you divide both sides by 2.
x = 36(3/2) = 108/2 = 54
Hence, the number of people on the hike is 54
5. What is the order of magnitude for the total weight of 5 cars that weigh 3,000 pounds each?6. 20,000 people voted in each county, and there are 7 counties. What is the order of magnitude for the total number of people who voted?
An order of magnitude is the class of scale of any amount in which each class contains values of a fixed ratio to the class preceding it. Usually, the amount scaled is 10, and the scale is the exponent applied to this amount.
Question 5
The weight of each car is 3,000 pounds. There are 5 cars in total. Therefore, the total weight is given to be:
[tex]\Rightarrow3000\times5=15000\text{ pounds}[/tex]Writing the calculated weight in standard form, scaling to 10, we have:
[tex]15000=1.5\times10^4[/tex]Therefore, the order of magnitude is 4.
Question 6
The number of people that voted per county is 20,000. There are 7 counties in total. Therefore, the total number of people that voted is:
[tex]\Rightarrow20000\times7=140000[/tex]Writing the calculated number in standard form, scaling to 10, we have:
[tex]140000=1.4\times10^5[/tex]Therefore, the order of magnitude is 5.

Of 100 students in a club,23 are freshman. What percent of the students are freshman ?
Answer
Percentage of students that are freshman = 23%
Explanation
Total number of students in a club = 100
Number of freshman = 23
Percentage of students that are freshman = [(Number of freshman)/(Total number of students in a club)] x 100
Percentage of students that are freshman = (23/100) x 100
Percentage of students that are freshman = 23%

On election day the polls open at 7:30 am and closes at 9pm. Marlene worked all day exceptfor a break at lunch 10:30 am to 12 pm and dthen break for dinner at 5:30 pm to 7 pm. Marleneworked What fraction of the time that the polls were open?(a) 4/7(b) *(C) ?(d)?(e) ?
ANSWER;
The fraction of the time she worked was 7/9 of the time the polls were opened
EXPLANATION;
Here, we want to get the fraction of the time in which Marlene worked
What we have to do here is to calculate the total time the pool was opened, then calculate the total time in which she went for break. Then we divide the break time by the total opening time
We proceed as follows;
From 7 : 30 am to 9pm
7:30 am to 9:30 pm is 14 hours
Kindly note that we are to subtract 30 minutes, so we have the total time as 13 hours and 30 minutes
For ease of calculations, we shall have all the time in minute
Recall, 60 minutes are in an hour
So, in 13 hours, we have 13(60) = 780 minutes
Added to the 30, we have a total of 780 minutes + 30 minutes = 810 minutes
Break Times
The first break is 10; 30 am to 12 pm; that is a total time of 1 hour 30 minutes
The second break is from 5:30 pm to 7 pm; that is another 1 hour 30 minutes
Total time spent on breaks is 3 hours
Converting to minutes, we simply multiply by 60 and that will give 3(60) = 180 minutes
Thus, we can now proceed to divide;
[tex]\frac{180}{810}\text{ = }\frac{6}{27}\text{ = }\frac{2}{9}[/tex]The above is the fraction spent on breaks. To get the farction worked, we simply subtract the above fraction from 1
We have this as;
