n = 9.828
n = –5.2
n = –9.828
QUESTION 5
Use a transformation to solve the equation.
–8c = 56
c = –48
c = 7
c = –7
c = 48
Answers
Question 4:
-2.34n = -12.168
Divide both sides by -2.34;
n = 5.2 is your answer to #4 (Answer choice "C.)"
For Question 5:
-8c = 56
Divide both sides by -8 to solve for c;
c = -7 (remember your signs!) is your answer for #5 (Answer choice "C.)"
[tex] \frac{n}{-12.168} [/tex] = -2; To solve for this, we need to multiply both sides by -12.168 to isolate and solve for our variable.
[tex] \frac{n}{-12.168} [/tex] = -2; Multiply by -12.168

A classic counting problem is to determine the number of different ways that the letters of "generally""generally" can be arranged. Find that number.
Answers
Final answer:
To determine the number of arrangements for the word 'generally', one calculates 9 factorial divided by the factorial of the counts of each repeated letter. With 'E' and 'L' repeating twice each, the calculation is 9! / (2! × 2!) resulting in 90720 unique arrangements.
Explanation:
Calculating Arrangements of the Word 'GENERALLY'
To calculate the number of different ways the letters in the word 'generally' can be arranged, we have to take into account the repeated letters. The word 'generally' has 9 letters with the following repetitions: G-1, E-2, N-1, R-1, A-1, L-2, and Y-1. The formula to calculate the permutations of a set of objects where there are duplicates is the factorial of the number of objects divided by the product of the factorials of the number of duplicates for each object.
Thus, to find the number of arrangements, we would calculate 9! (9 factorial) and then divide it by the product of the factorials of the repeated letters, which are E and L. This gives us 9! / (2! × 2!), or 362880 / (2 × 2), which simplifies to 90720 unique arrangements for the letters in 'generally'.
This combinatorial approach is a useful exercise in understanding how to count arrangements and can be applied more broadly to comprehend more intricate probability and statistics problems
A container holds 3 quarts of lemonade. How much is this in cups? Use the table below. Include the correct unit in your answer.
Answers
To find out how many cups are in 3 quarts of lemonade, you multiply the number of quarts (3) by the conversion factor of 4 cups per quart, giving you 12 cups of lemonade.
To answer the question, 3 quarts of lemonade is equivalent to how many cups, we will need to use the conversion between quarts and cups. In the United States customary system, 1 quart is equal to 4 cups. Therefore, to convert quarts to cups, you would multiply the number of quarts by 4.
To solve:
Multiply the number of quarts by 4 to convert to cups.3 quarts x 4 cups/quart = 12 cups
Thus, 3 quarts of lemonade is equivalent to 12 cups of lemonade.
What is the approximate length of the midsegment parallel to BC. the coordinates are B(-6,1) C(5,-1) ? please help
Answers
Step-by-step explanation:
Let the mid-point of BC is M. So, the length of BM = MC.
The coordinates of B are (-6, 1) and coordinates of C are (5, -1). Therefore, using the distance formula find the distance as follows.
d = [tex]\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}[/tex]
Place the values form points B and C into the above formula as follows.
d = [tex]\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}[/tex]
= [tex]\sqrt{(5- (-6))^{2} + ((-1)- (1))^{2}}[/tex]
= [tex]\sqrt{(11)^{2} + (-2)^{2}}[/tex]
= [tex]\sqrt{121 + 4}[/tex]
= [tex]\sqrt{125}[/tex]
= 11.18 (approx)
Therefore, the length of mid-point of line segment will be [tex]\frac{11.18}{2}[/tex] = 5.59 (approx). BM = MC = 5.59.
The length of line segment which is parallel to BC = [tex]\frac{d}{2}[/tex].

How do I find the value of z?
Answers
The answer is z = 16..
Solve it like this..
#1) Regroup terms
-3 = -7+z/4 ---> -3 = z/4 - 7
#2) Add 7 to both sides.
-3 = z/4 - 7 ---> -3 + 7 = z/4
#3) Do the addition.
-3 + 7 = z/4 ---> 4 = z/4
#4) Multiply both sides by 4.
4 = z/4 ---> 4 * 4 = z.
#5) Do the multiplication.
4 * 4 = z ---> 16 = z

livia wants to purchase a pair of shoes for $50.She also wants to huy some socks that cost $2.20 each.She only has $64.00 to spend.How many pairs of socks can she buy along with the shoes?
Ps:please tell me how you how you got it showing your work! Please thank you so much I need this answer ASAP
Answers
she wants to purchase socks that cost 2.20 each......so the expression for this is 2.20s...with s being the number of pairs of socks bought
and she only has $ 64....so she has to spend 64 or less...< = 64
so ur inequality would be :
50 + 2.20s < = 64.....subtract 50 from both sides
2.20s < = 64 - 50
2.20s < = 14...divide both sides by 2.20
s < = 14 / 2.20
s < = 6.36....so she can purchase 6 pairs of socks without going over
Subtract the cost of the socks from the budget.
64 - 50 = 14
Next, divide 14 by 2.20.
14 ÷ 2.20 = 6.36
So, Livia can buy 6 pairs of socks.

A line with a slope of 1/2 passes through the point 2,-1 what is the equation of this line
Answers
The equation of the line is [tex]\( y = \frac{1}{2}x - 2 \)[/tex].
To find the equation of a line with a given slope passing through a specific point, you can use the point-slope form of a linear equation: [tex]\( y - y_1 = m(x - x_1) \)[/tex], where ( m ) is the slope and [tex]\( (x_1, y_1) \)[/tex] is the given point.
Given that the slope [tex]\( m = \frac{1}{2} \)[/tex] and the point ( (2, -1) ), we substitute these values into the point-slope form:
[tex]\( y - (-1) = \frac{1}{2}(x - 2) \)[/tex]
This simplifies to:
[tex]\( y + 1 = \frac{1}{2}(x - 2) \)[/tex]
To remove the fraction, distribute [tex]\( \frac{1}{2} \)[/tex]:
[tex]\( y + 1 = \frac{1}{2}x - 1 \)[/tex]
Now, isolate ( y ) by subtracting 1 from both sides:
[tex]\( y = \frac{1}{2}x - 1 - 1 \)[/tex]
[tex]\( y = \frac{1}{2}x - 2 \)[/tex]
So, the equation of the line is [tex]\( y = \frac{1}{2}x - 2 \)[/tex].
Use doubles minus one to solve 8+7. Write the number sentence
Answers
Answer:
8+8-1 = 15
Step-by-step explanation:
The doubles minus one is the technique to add two numbers which are consecutive.In this technique you add double the greatest number of the two consecutive and then subtract 1 from the result.
Here we have equation 8+7.
so doubling the greater number (8+8) or (8*2) gives us 16.
then subtracting 1 from it (16-1) gives us 15
so 15 is our answer.
Using the doubles minus one strategy, the greater value of the expression is doubled and one subtracted from the sum. Hence, we have 8 + 8 - 1 = 15
Given the expression :
8 + 7
The greater value of the two digits is 8
Doubling the greater value : 8 + 8
Subtracting 1 from the sum of the doubled digit :
8 + 8 - 1 = 8 - 7 = 15
Therefore, the result of the expression is 15

What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
Roland sold 26 candy bars during the first week.
The number of treats he sold during the subsequent week was 4 under twice the quantity of pieces of candy he sold during the principal week.
Then the number of candies sold in the second week will be calculated as,
⇒ 2 x 26 - 4
⇒ 48
The number of sweet treats he sold during the third week was 6 a greater number than 1 ¹/₂ time the number of pieces of candy he sold during the subsequent week. Then the number of candies sold in third week will be given as,
⇒ 48 x (1 ¹/₂) + 6
⇒ 48 x 1.5 + 6
⇒ 72 + 6
⇒ 78
The total candies are calculated as,
⇒ 26 + 48 + 78
⇒ 152
The number of candy bars Roland sold during the three weeks will be 152.

The life expectancy of a typical lightbulb is normally distributed with a mean of 2,000 hours and a standard deviation of 27 hours. What is the probability that a lightbulb will last between 1,975 and 2,050 hours?
A. 0.17619
B. 0.32381
C. 0.79165
D. 0.96784
Answers
1 Standard deviation = 27 hours (we will approximate to 25 hours)
Mean = 2,000
This means that 34% of the distribution is between 1975 and 2000 hours (within 1 standard deviation below the mean)
2,000- 2,050 covers the range within 50 hours above the mean.
50 hours is roughly 2 standard deviations. The second standard deviation (standard deviation between 1 and 2) covers around 14% on each side of the distribution.
50 hours is roughly 2 standard deviations, which means we add 34% + 14% = 48%.
The range of 1,975 - 2,050 hours covers 34% of the distribution below the mean and 48% of the distribution above the mean.
This means that the probability that the light bulb will last somewhere within this range is 34% + 48% = 82%
The closest answer is 79%. The difference can be explained by the fact that, for simplicity, we approximated the standard deviation to be ~25 hours instead of the real standard deviation of 27 hours.
