Answer:
I think you're looking for 74,099
I need help please !!
Step-by-step explanation:
A has no solution.
15x - 45 = 15x + 75
-45 = 75
is false for every value of x.
in other words, when you add to the same thing different amounts, the result cannot be identical ever.
B has a solution
-45x - 45 = -75x + 75
-120x = 120
-x = 1
x = -1
C has a solution
45x - 45 = -15x + 75
60x = 120
x = 2
D has a solution
15x - 45 = 75x + 75
-120 = 60x
-2 = x
I need to know the price of 15% for all of them
Here is the completed table:
Name of the food Price with 15% profit
Apple (whole) $9.20
Banana (whole) $8.34
Chocolate (whole) $6.90
Chocolate chip ( 1 dozen) $5.46
Oatmeal ( 1 dozen) $5.75
Pecan (whole) $11.50
Pumpkin (whole) $13.80
Snickerdoodle ( 1 dozen) $4.89
Vanilla (whole) $5.18
What are the prices with 15% profit?Percentage is used to represent statistics. Percentage means to rewrite a number per hundred. To convert a number to percentage, multiply the number by 100. The sign that is used to represent percentage is %.
Profit is the excess of the cost of production over the price at which the good is sold.
Profit = ( 1 + targeted profit) x cost
= (1 + 0.15) x cost
1.15 x cost
Profit on Apple (whole) = 1.15 x 8 = $9.20
Profit on Banana (whole) = 1.15 x 7.25 = $8.34
Profit on Chocolate (whole) = 1.15 x 6 = $6.90
Profit on Chocolate chip ( 1 dozen) = 1.15 x 4.75 = $5.46
Profit on Oatmeal ( 1 dozen) = 1.15 x 5 = $5.75
Profit on Pecan (whole) = 1.15 x 10 = $11.50
Profit on Pumpkin (whole) = 1.15 x 12 = $13.80
Profit on Snickerdoodle ( 1 dozen)= 1.15 x 4.25 =$4.89
Profit on Vanilla (whole) = 1.15 x 4.5 = $5.18

How much credit is left on the card after Keith uses it for 30 minutes of calls
The credit that is left on the card after Keith uses it for 30 minutes of calls is $48.35.
How to calculate the cost?From the information given, Keith purchased a prepaid phone card for $50.75. Calls cost 8 cents a minute using this card
The equation was given as C=50.75-0.08x
Therefore, the credit that is left on the card after Keith uses it for 30 minutes of calls will be:
C=50.75-0.08x
C = 50.75 - 0.08(30)
C = 50.75 - 2.40

You are running a left-tailed 2-sample z-test at the 0.05 level of significance and you find a test statistic of z=-1.87. shoudl you reject or not reject the null?
Using the critical value, we should reject the null.
What is a test statistic?A test statistic is a quantity derived from a sample that is used in statistical hypothesis testing. A hypothesis test is usually specified in terms of a test statistic, which is a numerical summary of a data set that reduces the data to a single value that can be used to perform the hypothesis test. In general, a test statistic is chosen or defined in such a way that it quantifies, within observed data, behaviors that distinguish the null hypothesis from the alternative hypothesis, where such an alternative is prescribed, or that characterize the null hypothesis if no alternative hypothesis is explicitly stated.So,
Test = 2.85Critical value = Z(0.05) = 1.645RR: Reject if the Z test > 1.645Z test = 2.85 > 1.645 ⇒ RejectTherefore, using the critical value, we should reject the null.

Explain the difference between partitioning a directed line segment MN in a 2:7 ratio
versus a 7:2 ratio. Include a specific example as part of your explanation.
The difference between partitioning a directed line segment MN in a 2:7 ratio versus a 7:2ratio because of following
To understand this let us take the line segment MN which is of a length is divided into 9 equal parts. Here, we are dividing it into nine parts because the proportions 2 and 7 make a sum of 9.
When we divide the line segment MN in the ratio 2:7, the first two parts out of the nine from the left side are separated from the rest 7. This means that the first proportion from the left hand side of the line is smaller than the other.
Now, when we divide the line segment MN in the ratio7:2, the first seven parts out of the nine from the left side are separated from the rest two. This means that the first proportion from the left hand side of the line is larger than the other.

The depth of a local lake averages 38 ft, which is represented as |−38|. In February, it measured 6 ft deep, or |−6|, and in July, it was 25 ft deep, or |−25|. What is the difference between the depths in February and July?
32 feet
31 feet
19 feet
13 feet
The difference between the depths in February and July is 19 feet.
To find the difference between the depths in February and July, we need to subtract the depth in February from the depth in July.
The depth in February is given as |−6|, which is 6 feet, and the depth in July is given as |−25|, which is 25 feet.
Difference = Depth in July - Depth in February
Difference = 25 feet - 6 feet
Difference = 19 feet
Therefore, the difference between the depths in February and July is 19 feet.In February, the depth of the lake is given as |−6|, which represents the absolute value of -6. The absolute value of a number disregards its sign, so |−6| is equal to 6 feet.
In July, the depth of the lake is given as |−25|, which represents the absolute value of -25. Again, disregarding the sign, |−25| is equal to 25 feet.
To find the difference between the depths in February and July, we subtract the depth in February from the depth in July:
Difference = Depth in July - Depth in February
Difference = 25 feet - 6 feet
Difference = 19 feet
Therefore, the difference between the depths in February and July is 19 feet. This means that the lake experienced a change of 19 feet in depth between those two time points.

Keep in mind that two line segments do not always need to intersect. In the illustration above, move point B higher until the intersection of the two line segments disappears.

a company's charge for electricity is ¢6.434 per kilowatt-hour. in addition, each monthly bill contains a customer charge of $7.81. if last year's bills ranged from a low of $51.74 to a high of $192.28, over what range did usage vary (in kilowatt-hours)?
The range did usage vary over from 823.81 to 2461.97 kilowatt-hours.
What is kilowatt-hour?Kilowatt-hours are units of energy that represent one kilowatt of electricity for one hour (SI symbol: kWh or kWh; typically abbreviated as kWh). It is 3.6 megajoules in terms of standard units (MJ). For electrical energy supplied to customers by electric utilities, kilowatt-hours are a typical billing unit. The abbreviation "kWh," which is derived from the letters kilowatt and hour, stands in for the kilowatt-hour and is a commonly used abbreviation. In addition to being often used in commercial, academic, and scientific publications as well as in the media, it is also frequently employed by electric utility companies to bill consumers for energy delivered to them. One kilowatt (kW) sustained for one hour (multiplied by one) is equivalent to one kilowatt-hour, a composite unit of energy.
$64.34=6434 cents
$192.28=19228 cents
So 6434 cents correspond to 6434/7.81
=823.81 kilo watt hours
19228 cents=19228/7.81
=2461.97 kilowatt-hours

Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
2y + 50 + y + 10 = 180
3y + 60 = 180 ( subtract 60 from both sides )
3y = 120 ( divide both sides by 3 )
y = 40
2y = 2 × 40 = 80
y + 10 = 40 + 10 = 50
Answer:
y = 40
2y = 80
y + 10 = 50
Step-by-step explanation:
The sum of the angles of a triangle is 180°
Using values given,
2y + (y + 10) + 50 = 180
2y + y + 10 + 50 = 180
3y + 60 = 180
3y = 180-60 = 120
y = 120/3 = 40
2y = 80
y + 10 = 40 + 10 = 50

A) The rate for the first 3 years :
15,600 - 7500 = 8100
8100/3 years = 2,700 per year depreciation.
B) The rate between 3 and 8 years:
