Kelly says that she can find the change by subtracting -5.1 from the temperature
at 12 PM on Wednesday.
Who is correct? Use the drop-down menus to explain your reasoning and find the
change in temperature.
and the distance from 0 to the Wednesday 12 PM temperature is 2.5
Steve is correct. Steve can find the difference in temperature between 7 AM and 12 PM on Wednesday by adding the distances from 0.
By using a number line, Steve can find the difference in temperature between 7 AM and 12 PM on Wednesday by adding the distances from 0. One temperature is negative and the other is positive, but by adding their distances, he can find the difference. Kelly's method of subtracting -5.1 from the temperature at 12 PM on Wednesday is not necessarily incorrect, but it does not give the exact difference in temperature between the two times. Therefore, using Steve's method, the change in temperature would be the sum of the distance from 0 to the temperature at 7 AM (which is 2.5) and the distance from 0 to the temperature at 12 PM (which is also 2.5), resulting in a difference of 5 degrees.

The diagram shows triangle ABC.

Angle CDB = 90°
Angle DCB = 40°
Work out the size of angle EAD. Give your answer correct to 1 decimal place.
You must show all your working.
Please help
The size of angle EAD is 40°.
To find the size of angle EAD, we can use the information given in the diagram and apply some basic trigonometry principles. Let's go step by step.
First, we notice that triangle CDB is a right triangle since angle CDB is given as 90°. We also know that angle DCB is 40°. This means that angle CBD can be found by subtracting 40° from 90°:
angle CBD = 90° - 40° = 50°.
Since E is the midpoint of DB, we can conclude that angle CBE is also 50°, as it is vertically opposite to angle CBD.
Now, let's consider triangle ADE. We know that angle EAD is the angle we're trying to find. We can use the fact that the angles in a triangle add up to 180° to write the equation:
angle EAD + angle ADE + angle DEA = 180°.
Since E is the midpoint of DB, we can conclude that angle ADE is equal to angle CDE. Angle DEA is equal to angle CEA. Therefore, we can rewrite the equation as:
angle EAD + angle CDE + angle CEA = 180°.
We can substitute the values we know: angle CDE is 90° (since it's a right angle), and angle CEA is 50° (since it's vertically opposite to angle CEB).
angle EAD + 90° + 50° = 180°.
Simplifying the equation:
angle EAD = 180° - 90° - 50° = 40°.
Therefore, the size of angle EAD is 40°.

A pound of flour costs $12. How many ounces of flour can be purchased for $3.30?
Answer:
4.4 ounces/ 4 ounce (if rounded)
Step-by-step explanation:
There are 16 ounces in a pound, therefore the equation 12/16 will be useful since 16 ounces in a pound can be divided by 12, in conclusion 12/16=0.75 which is how much an ounce costs.
Then you will take $3.30 and divide it by 0.75 to get your answer for how many ounces you can buy for $3.30 which will equal 4.4 ounces but if you were to round it would be 4 ounces

- Darrell Morris has a family plan. The HMO annual premium is $12,240. The employer pays 90% of the cost.
a) How much is Darrell's annual contribution? b) How much is his semimonthly deduction?
Answer:The employer pays .90 * 12240 = $ 11016. The emplyee pays .10 *12240 = $ 1224 = annual contribution. Contribution rate = (100% - 90%) = 10%.
Step-by-step explanation:
Answer:
a) $1,224
b) $51
Step-by-step explanation:
a) To calculate Darrell's annual contribution, we need to determine the portion he pays out of the total premium.
Given that the employer pays 90% of the cost, Darrell is responsible for the remaining 10%.
Annual contribution = Total premium × 10%
= $12,240 × 0.10
= $1,224
Therefore, Darrell's annual contribution is $1,224.
b) To find Darrell's semimonthly deduction, we divide his annual contribution by the number of semimonthly periods in a year.
Number of semimonthly periods in a year = 12 (months) × 2 (semimonthly periods per month) = 24
Semimonthly deduction = Annual contribution / Number of semimonthly periods
= $1,224 / 24
= $51
Therefore, Darrell's semimonthly deduction is $51.

the difference between 4/9 of a number and 7 is 5
first what quantities do we need to talk about?
the problem speaks of “a number”, let’s call that number x.
now write the equation that relates x to the other numbers we know.
the first clue is the word “difference”.
this means “subtraction”, but we need to subtract something from something else.
what are the two somethings? ”a number times 7” and “4”.
so, since we have a name for “a number”, let’s translate this as x*7 - 4 what else do we know?
it says the difference is 9. So complete the equation x*7 - 4 = 9 if we rewrite this cosmetically, 7x - 4 = 9
i assume that you know how to solve this for x.
so then wehn solving 7x - 4 =9 we take -4 change it to +4 so then +9 we go and get 13
7x = 13
7/7 = 13/7

\(y \geq -3x + 2\\\\y \leq x + 3\)
is the equation of the given system.
Equation of the line using the coordinates (-3, 0) and (0, 3), we get:
slope = (3 - 0) / (0 - (-3)) = 1
Now we have the slope of the line. Next, we can use the point-slope form of the equation of a line, which is:
y - y1 = m(x - x1)
where m is the slope and (x1, y1) is a point on the line.
Using the point (-3, 0) and the slope we just found (which is also the slope of the line passing through the point (0, 3)), we get:
y - 0 = 1(x - (-3))
Simplifying, we get:
y = x + 3
Therefore, the equation of the line passing through (-3, 0) and (0, 3) is y=x+3.
Similarly, the equation of the line passing through (1, -1) and (0, -4) is y = -3x + 2.

in a data set consisting of 30 positive integers, the minimum value is 13. the number 6 is added to the original set to create a set of 31 positive integers. which of the following measures must be 7 greater for the new data set than for the original data set?
a. The mean
b. The median
c. The range
d. The standard deviation
The mean, median, range, and standard deviation for the new data set must all be 7 greater than for the original data set.
The mean is the sum of all the values divided by the number of values. Adding the number 6 to the original data set of 30 positive integers increases the sum of all the values by 6, which means the mean for the new data set must be 7 greater than the mean for the original data set.
The formula for the mean is: Mean = (Sum of Values)/(Number of Values)
For the original data set: Mean = (Sum of Values)/30
For the new data set: Mean = (Sum of Values + 6)/31
Therefore, the mean for the new data set must be 7 greater than the mean for the original data set.
The median is the middle value in a set of data. Adding the number 6 to the original data set of 30 positive integers increases the total number of values to 31, which means the median is calculated differently for the new data set than the original data set. The median for the new data set must be 7 greater than the median for the original data set.
The formula for the median is: Median = (n+1)/2
For the original data set: Median = (30+1)/2 = 15.5
For the new data set: Median = (31+1)/2 = 16.5
Therefore, the median for the new data set must be 7 greater than the median for the original data set.
The range is calculated by subtracting the smallest value from the largest value in a data set. Adding the number 6 to the original data set of 30 positive integers increases the largest value by 6, which means the range for the new data set must be 7 greater than the range for the original data set.
The formula for the range is: Range = (Largest Value) - (Smallest Value)
For the original data set: Range = (Largest Value) - 13
For the new data set: Range = (Largest Value + 6) - 13
Therefore, the range for the new data set must be 7 greater than the range for the original data set.
The standard deviation is a measure of how spread out the values in a data set are. Adding the number 6 to the original data set of 30 positive integers increases the total number of values by 1, which means the standard deviation for the new data set must be 7 greater than the standard deviation for the original data set.
The formula for the standard deviation is: Standard Deviation = √ (Sum of (Values - Mean)2 / Number of Values)
For the original data set: Standard Deviation = √ (Sum of (Values - Mean)2 / 30)
For the new data set: Standard Deviation = √ (Sum of (Values - Mean)2 / 31)
Therefore, the standard deviation for the new data set must be 7 greater than the standard deviation for the original data set.
