m=(9-0)/(7-4)
m=9/3
m=3
2)
m=(y2-y1)/(x2-x1)
m=(4-2)/(6-9)
m=2/(-3)
m=-2/3
3)
m=(y2-y1)/(x2-x1)
m=(3-(-1))/4-4)
m=4/0

A puppet show crew uses a timer that includes both negative and positive minutes for before and during the play. If it takes the crew 40 minutes to assemble the box stage, 13 minutes to organize the sock puppets, and 10 minutes to greet the children, what time should the timer read when they begin?
–63 minutes
–17 minutes
0 minutes
53 minutes
Answer:
63 minutes
Step-by-step explanation:
40+13+10 = 63
Answer:
-63
Step-by-step explanation:
The time before the play are negative and the tmes during the play are positive
assembly = 40 min
organising the puppets = 13 min
greeting children = 10 min
All the above are done before the actual start of the play so they will be recorded in negative minutes
Total time:
(-40) + (-13) + (-10)
= - 40 - 13 - 10
= -63

Use a number line to order the numbers from least to greatest.
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25

say there are 2 candles per every 20 cakes. How many candles would there be for every 60 cakes?
Im using an analogy for my question bc its monitored 3
Answer:
There would be 6 candles.
Step-by-step explanation:
So you said that there would be 2 candles per 20 cakes, so I simplified it to 1 candle per 10 cakes. So, if there were 60 cakes, there would be 6 candles.
I hope it helped!
~Flipohrama
Answer:
6
Step-by-step explanation:
If you do 60/20 you get 3. Then you would 3 times 2 for every 2 candles. Your answer would be 6 because 2 times 3 equals 6.
\(\frac{5}{6} - \frac{1}{2} - \frac{1}{6}\)
Answer:
1/6
Step-by-step explanation:
So first you want to get the common denominators. So you want to times 1/2 by three which gives you 3/6. So if you subtract 3/6 from 5/6 you get 2/6 and if you subtract 1/6 from 2/6 you get 1/6.
PLEASE HELP!!!
Lee can type 1 1/3 pages every 15 minutes. How many hours does it take him to type 10 2/3 pages? Complete the rate table to solve the proportion.
pages---> 4/3=32/3
hours---> 1/4 = x
Lee can type 10 2/3 pages in _________ hours.
a. 1 3/4
b. 2
c. 2 1/4
d. 2 1/2
Answer:
First, we know that:
1 1/3 = 4/3
10 2/3 = 32/3
15 minutes = 0.25 hours
Let's imagine that x (hours) is the time it takes Lee to type 32/3 pages.
From the information, we can tell that:
Lee can type:
4/3 pages in 0.25 hours
32/4 pages in x hours
So x should be:
x = (32/4 . 0.25)/4/3 = 2 (hours)
So it takes Lee 2 hours ro type 10 2/3 pages

Need help with trig problem in pic
Answer:
a) \(cos(\alpha)=-\frac{3}{5}\\\)
b) \(\sin(\beta)= \frac{\sqrt{3} }{2}\)
c) \(\frac{4+3\sqrt{3} }{10}\\\)
d) \(\alpha\approx 53.1^o\)
Step-by-step explanation:
a) The problem tells us that angle \(\alpha\) is in the second quadrant. We know that in that quadrant the cosine is negative.
We can use the Pythagorean identity:
\(tan^2(\alpha)+1=sec^2(\alpha)\\(-\frac{4}{3})^2 +1=sec^2(\alpha)\\sec^2(\alpha)=\frac{16}{9} +1\\sec^2(\alpha)=\frac{25}{9} \\sec(\alpha) =+/- \frac{5}{3}\\cos(\alpha)=+/- \frac{3}{5}\)
Where we have used that the secant of an angle is the reciprocal of the cos of the angle.
Since we know that the cosine must be negative because the angle is in the second quadrant, then we take the negative answer:
\(cos(\alpha)=-\frac{3}{5}\)
b) This angle is in the first quadrant (where the sine function is positive. They give us the value of the cosine of the angle, so we can use the Pythagorean identity to find the value of the sine of that angle:
\(cos (\beta)=\frac{1}{2} \\\\sin^2(\beta)=1-cos^2(\beta)\\sin^2(\beta)=1-\frac{1}{4} \\\\sin^2(\beta)=\frac{3}{4} \\sin(\beta)=+/- \frac{\sqrt{3} }{2} \\sin(\beta)= \frac{\sqrt{3} }{2}\)
where we took the positive value, since we know that the angle is in the first quadrant.
c) We can now find \(sin(\alpha -\beta)\) by using the identity:
\(sin(\alpha -\beta)=sin(\alpha)\,cos(\beta)-cos(\alpha)\,sin(\beta)\\\)
Notice that we need to find \(sin(\alpha)\), which we do via the Pythagorean identity and knowing the value of the cosine found in part a) above:
\(sin(\alpha)=\sqrt{1-cos^2(\alpha)} \\sin(\alpha)=\sqrt{1-\frac{9}{25} )} \\sin(\alpha)=\sqrt{\frac{16}{25} )} \\sin(\alpha)=\frac{4}{5}\)
Then:
\(sin(\alpha -\beta)=\frac{4}{5}\,\frac{1}{2} -(-\frac{3}{5}) \,\frac{\sqrt{3} }{2} \\sin(\alpha -\beta)=\frac{2}{5}+\frac{3\sqrt{3} }{10}=\frac{4+3\sqrt{3} }{10}\)
d)
Since \(sin(\alpha)=\frac{4}{5}\)
then \(\alpha=arcsin(\frac{4}{5} )\approx 53.1^o\)

The number that is four greater than three times its additive inverse
is - 3n + 4.
What are additive and multiplicative inverses?A number's additive inverse is a number that is added to it until the result is zero.
A number multiplied by another such that the result is 1 is the multiplicative inverse of that number.
Let the unknown number be 'n' so its additive inverse is '-n'.
So, the number that is four greater than three times its additive inverse is,
Three times of additive inverse is -3n.
Now the number is 4 greater than 3 times its additive inverse which is
= - 3n + 4.

James buys 4 pens for $3. Which three points lie on the line that best represents the total cost, y, of x pens?
Which order pair is NOT on the line that best represents this relationship?
Responses (8,6) (4,3) (0,0) (6,8)
James buys 4 pens for $3, so each pen costs $3/4. The total cost of x pens is $3x/4.
The points (0,0), (4,3), and (8,6) all lie on the line y = $3x/4. The point (6,8) does not lie on this line.
Therefore, the answer is (6,8).

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Area of five squares = 1289.09 square units
Perimeter = 194.6 units
Step-by-step explanation:
Area of square and perimeter:
First find the length of each square, then find the area of each square.
To find the area of five squares, add all the area of each square.
Side of square1 = 27 units
\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)
Area of square1 = 27*27 = 729 square units
Area of square2 = 18*18 = 324 square units
Area of square3 = 12*12 = 144 square units
Area of square4 = 8*8 = 64 square units
Area of square5 = 5.3*5.3 = 28.09 square units
Area of five squares = 729 + 324 + 144 + 64 +28.09
= 1289.09 square units
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)
= 90 + 42 + 28 + 18.7 + 15.9
= 194.6 units
