Usually it takes Mrs. Manny 5.2 hours to grade her students' assignments. Thisweekend, her daughter Lexi is home and has offered to help. If it would take Lexi 6.4hours to grade the papers alone, how long will it take the two to finish the task of grading,working together?
Mrs. Manny needs 5.2 hours to grade her students' assignments. It would take Lexi 6.4 hours to grade the assignments alone.
In one hour, Mrs. Manny completes 1 / 5.2 = 0.1923 of the work.
In one hour, Lexi completes 1 / 6.4 = 0.15625 of the work
Together, they complete 0.1923 + 0.15625 = 0.34856 of the work.
The full work would take them 1 / 0.34856 = 2.87 hours.
It would take 2.87 hours for them to finish the task together.
у 10 8 P 4 2 0 2 6 8 10 Which ordered pair represents the location of point P on the coordinate plane? a (5,6) b (6,5) (6,7) d (7,6)
The ordered pair that represents the location of point P is (6,5)
Explanation:
In order to determine the position of point P, we will need to trace its position to the x axis and also trace its position to the y axis.
Tracing its position to the x axis, we find it corresponds to 6 units
Tracing its position to the y axis, we find it corresponds to 5 units.
This because each line represents 1 units. After the 4 units, the next line is 5 units.
Using the coordinates (x,y):
The ordered pair that represents the location of point P is (6,5)

i need help please with m and b#1 and graph
ANSWER
• m = 2
,• b = -5
EXPLANATION
This equation is written in slope-intercept form,
[tex]y=mx+b[/tex]Where m is the slope and b is the y-intercept.
In this case, the slope is m = 2 and the y-intercept is b = -5. This tells us that the line intersects the y-axis at y = -5, so that is our first point. Then, we can find the next point using the slope,
[tex]m=2=\frac{\Delta y}{\Delta x}[/tex]The next point is 1 unit to the right of the y-intercept, and 2 units up,

Jenny has a deck of 52 alphabet cards (26 uppercase and 26 lower case). Jenny selects one card.What is the probability that she selects a vowel?
We know that we have five vowels in the alphabet. Since the deck has uppercase and lower case cards this means that it has a total of 10 vowels.
The probability is given by the quotient between the number of favorable outcomes and the number of total outcomes; then in this case we have:
[tex]P=\frac{10}{52}=\frac{5}{26}[/tex]Therefore the probability of selecting a vowel is 5/26
accounts that earn 6% interest. If Emma’saccount earns simple interest and Paul’saccount earns compound interest, which is thevalue of each person’s account after 8 years?A. Emma – $2,960; Paul – $3,187.708. Emma – $960; Paul – $3,187.70C. Emma – $2,960; Paut- $ 1,187.70
So,
Remember that the simple interest of an initial amount after "t" years, can be found using the following formula:
[tex]A=P(1+rt)[/tex]Where A is the final amount, P is the initial amount, r is the rate and t are the years involved.
If we replace our values, Emma will has the following amount after 8 years:
[tex]\begin{gathered} A=2000(1+\frac{6}{100}(8)) \\ A=2960 \end{gathered}[/tex]So, Emma will has $2,960 after 8 years.
To find the amount that Paul will has, we should remember what the compound interest is.
Remember that the compound interest is given by the formula:
[tex]A=P(1+i)^n[/tex]Where A is the final amount, P is the initial amount, i is the rate and n are the years involved.
If we replace our values, Paul will has the following amount of money after 8 years:
[tex]\begin{gathered} A=2000(1+\frac{6}{100})^8 \\ A=3187.70 \end{gathered}[/tex]So, Paul will has $3187,70 after 8 years.
Therefore, the correct answer is A.
About how far does the flag have to travel to complete full rotation?1. 37.68 ft2. 75.36 ft3. 150.72 ft4. 452.16 ftPlease explain if possible!
Due to the circular shape, one complete rotation of the flag is equal to the circumference of a circle with radius 12 ft.
Then, use the following formula for the cirumference:
C = 2π·r
where r is the radius. In this case, r = 12 ft and π = 3.14. Replace the previous values into the formula for C:
C = 2(3.14)(12 ft)
C = 75.36 ft
Hence, the flag has to travel 75.36 ft to complete a full rotation

Acetone (fingernail polish remover ) has a density of 0.7857 g/cm^3.A) what is the mass in grams of 17.56 mL of acetone?B) what is the volume in milliliters of 7.22 g of acetone?
We can use density as a factor of conversion.
To find the mass in grams of the volume of acetone, multiply the volume by the density (always check the units, that in this case are consistent because 1cm^3=1mL):
[tex]17.56mL\cdot\frac{0.7857g}{mL}=13.79g[/tex]To find the volume of the mass of acetone, divide the mass by the density:
[tex]7.22g\cdot\frac{1mL}{0.7857g}=9.18mL[/tex]9. A coin is tossed and a number cube is rolled. What is the probability of getting tails and rolling a two?
Okay, here we have this:
Considering the provided information, we are going to calculate the requested probability, so we obtain the following:
Probability of getting tails and rolling a two=Probability of getting tails * Probability of getting a two
And basing ourselves on the fact that when tossing a coin there are two possible events and in this case a favorable one, and when tossing the die there are 6 possible events and one favorable for this case, we have:
Probability of getting tails and rolling a two=1/2*1/6
Probability of getting tails and rolling a two=1/12
Finally we obtain that the probability of getting tails and rolling a two is 1/12.

Solution:
Step 1: Find the slope of the line:
Given the points (X1, Y1)=(-4,-5) and (X2, Y2)= (1,5), we have that the slope of the line that passes through the points (-4,-5) and (1,5) is:
[tex]m=\frac{Y2-Y1}{X2-X1}=\frac{5+5}{1+4}=\frac{10}{5}=2[/tex]Step 2: Write the provisional equation of the given line. If the slope of the line is m=2, we get that the provisional equation of this line is:
[tex]y\text{ =2x+b}[/tex]Step 3: Find the y-intercept b. Take any point (x,y) on the line and replace its coordinates into the above equation and then solve for b. For example, take the point (x,y)=(1,5), then we obtain:
[tex]5\text{ =2(1)+b}[/tex]this is equivalent to:
[tex]5\text{ =2+b}[/tex]solving for b, we get:
[tex]b\text{ = 5-2 = 3}[/tex]that is:
[tex]b\text{ = 3}[/tex]Step 4: Write the equation of the line. If the given line has slope m=2 and y-intercept b = 3, then its equation would be:

The coordinates of the quadrilateral after translation will be : A'( 0 , 6 ) , B'( 6 , 4) , C'( 0 , 1 ) and D'( 4 , -2 )
The given quadrilateral in the graph has the coordinates:
A(1,8) , B(7,7) , C(1,4) , D(5,4)
When this figure is translated 1 unit to the left and 3 units downwards we get :
A ( 1 , 8 ) → A'( 0 , 5 )
B ( 7 , 7 ) → B'( 6 , 4 )
C ( 1 , 4 ) → C'( 0 , 1 )
D ( 5 , 4 ) → D'( 4 , 1 )
Hence the translated figure will have the coordinates:
A'( 0 , 6 ) , B'( 6 , 4) , C'( 0 , 1 ) and D'( 4 , -2 ) .
In Euclidean geometry, a translation or transformation is still a geometric change that entails shifting every point in a figure, shape, or space uniformly in one direction.
Moving the origin of the coordinate system or adding a constant vector to each point are other ways to conceptualize translation.
