Answer:
18 daysStep-by-step explanation:
Remember :
Number of workers is inversely proportional to the amount of days requiredHere :
6 workers construct 10 m long wall in 4 daysThen, for 2 workers to construct the same length, it will take 3 times the amount of time as number of men has been divided by 32 workers to construct 10 m long wall = 4 x 3 = 12 daysFor them to construct 15 m long wall, multiply the number of days by 1.5 as 10 x 1.5 = 15No. of days for 2 workers to construct 15 m long wall :12 x 1.5 = 18 daysAnnabeth logged onto her computer for school at 1:09 pm she paused for a snack break for 30 minuted then started again and then she logged off at 3:47 pm. How long was Annabeth on the computer for?
Starting time:-
1:09PM=13:09+0:30=13:39Now
Ending time:-
3:47PM=15:47PMTotal active time:-
15:47-13:392:08hoursOr
2hours 8minAnswer:
2 hours 8 minutes
Step-by-step explanation:
Let the total amount of time of Annabeth's being on the computer be x hours
since she paused using computer for a snack break for 30 minuted, our x turns out to be
[tex]x+0:30[/tex]
The initial time is 1:09 pmThe final time is 3:47 pmThus our equation would like
[tex]1:09+x+0:30=3:47[/tex]solving the equation yields:
[tex]1:09+x+0:30=3:47\\\implies 1:39+x=3:47\\\implies x=3:47-1:39\implies \boxed{x=2:08}\rm hours [/tex]
hence,
Annabeth was on her computer for 2 hours 8 minutes

The equation in slope-intercept form of the line that passes through the point (2,-2) and is perpendicular to the line represented by y = x + 2 is y = -1/2 - 3
Equation of a lie in slope-interceptThe equation of a line in slope intercept form is expressed as:
y = mx + c
m is the slope
c is the intercept
Given the equation of a line y = x + 2, the slope of the line perpendicular is -1/2. If this line pass through the point (2, -2), the required equation will be
y - (-2) = -1/2(x+2)
2(y+2) = -(x+2)
2y + 4 = -x - 2
2y = -x - 6
y = -1/2 - 3
Hence the equation in slope-intercept form of the line that passes through the point (2,-2) and is perpendicular to the line represented by y = x + 2 is y = -1/2 - 3

Answer:
B is your answer: Angle pair "MTS" should be 107 and "STN" should be 73
Step-by-step explanation:
You need to do 180-73 because "s" is unknown.
That should be 107 degrees.
Angle pair "MTS" should be 107 and "STN" should be 73
This is due to alternate interior angles, same side angles, and congruency properties.

Assuming that the families use the same appliances in the same way, who spends more to run these appliances in a given 30 day period and by how much? a. the reed family spends $13.80 more than the merrill family. b. the reed family spends $0.46 more than the merrill family. c. the merrill family spends $58.80 more than the reed family. d. the merrill family spends $18.60 more than the reed family.
The family who spends more to run these appliances in a given 30 day period is given by: Option A: The reed family spends $13.80 more than the merrill family.
How to interpret integral multiplication?Suppose that there are two positive integer numbers( numbers like 1,2,3,.. ) as a and b
Then, their multiplication can be interpreted as:
[tex]a \times b = a + a + ... + a \: \text{(b times)}\\\\a \times b = b + b +... + b \: \text{(a times)}[/tex]
For example,
[tex]5 \times 2 = 10 = 2 + 2 + 2 + 2 + 2 \: \text{(Added 2 five times)}\\or\\5 \times 2 = 10 = 5 + 5 \: \text{(Added 5 two times)}[/tex]
For this case, the missing table for expenses of both families is:
Reed Family Appliances
Gas range 5 cents per day
Gas dryer 1 load per day-10 cents per load
Electric water heater 90 cents per day
Typical later model refrigerator 16 cents per day
Total cost per day 5+10+90+16= 166 cents = $1.21
Merrill Family Appliances
Electric range 13 cents per day
Gas dryer - 1 load per day 10 cents per load
Gas water heater 40 cents per day
Energy Star-labeled refrigerator 12 cents per day
Total cost per day 13+10+40+12 = 75 cents = $0.75
Since each of them used these appliances for 30 days, so we get:
Case 1: Expense by Reed Family in 30 days:Expense in 30 days = [tex]30 \times[/tex] expense per day
Expense in 30 days = [tex]30 \times 1.21 = \$36.3[/tex]
Case 2: Expense by Merrill Family in 30 days:Expense in 30 days = [tex]30 \times[/tex] expense per day
Expense in 30 days = [tex]30 \times 0.75 = \$22.5[/tex]
So, Reed family spent more.
The difference is $36.3 - $22.5 = $13.80
Thus, the family who spends more to run these appliances in a given 30 day period is given by: Option A: The reed family spends $13.80 more than the merrill family.

3. Over what interval is the function decreasing?
The derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′(x) > 0 at each point in an interval I, then the function is said to be increasing on I. f′(x) < 0 at each point in an interval I, then the function is said to be decreasing on I.
Answer:
x∈(-∞; 0).
Step-by-step explanation:
1) the given function is a parabola with its vertex in (0;0). Then
2) the increasing interval is (0:+∝), decreasing interval is (-∝;0).

20 POINTS!!!! ill mark brainliest! The hypotenuse of the triangle measures 18, what is the radius of circle A? Is the radius the same all around?
Answer:
The radius is 3 and it is the same all around
Step-by-step explanation:
Since The hypotenuse equals the two other sides squared, let's find out what those are.
[tex]\sqrt{9} + \sqrt{9} = \sqrt{18}[/tex]
Now, let's find the square root of those 9s.
[tex]\sqrt{9} = 3[/tex]
Those other sides we talked about (more specifically the base of the triangle) are the radius of the circle because of how they extend to the exterior of the circle, which means since their length is 3, the radius is also 3.
The radius is always constant so it is supposed to be the same all around.

4 < x < 10
–5 < x < 2
x < 4 or x > 10
x < –5 or x > 2
The questions are illustrations of inequalities
The solution to the inequality is 7 < x < 11The range of the function is (c) R: {f(x) ∈ ℝ | f(x) > 5}The solution to the inequality is x < –5 or x > 2The solution to the inequalityThe inequality is given as:
x² - 18x < -77
Add 77 to both sides
x² - 18x + 77 < 0
Expand the inequality
x² - 7x - 11x + 77 < 0
Factorize the inequality
x(x - 7) - 11(x - 7) < 0
Factor out x - 7
(x- 7)(x - 11) < 0
Solve for x
x < 7 or x < 11
This means that the solution to the inequality is 7 < x < 11
The graph that represents the solutionThe inequality expression is given as:
y ≤ x² + 2
See attachment for the graph of the inequality
The range of the functionThe function is given as:
f(x) = |x| + 5
The smallest value of |x| is 0.
So, we have:
f(x) > 0 + 5
Evaluate
f(x) > 5
Hence, the range of the function is (c) R: {f(x) ∈ ℝ | f(x) > 5}
The solution to the inequalityThe inequality expression is given as:
|2x + 3| < 7
Remove the absolute expression
2x + 3 < 7 or 2x + 3 < -7
Subtract 3 from both sides
2x < 4 or 2x < -10
Divide both sides by 2
x < 2 or x < -5
