Answer:
tanΘ = - [tex]\frac{24}{7}[/tex]
Step-by-step explanation:
Given
cosΘ = [tex]\frac{7}{25}[/tex] = [tex]\frac{adjacent}{hypotenuse}[/tex]
The right triangle has sides 7, 24, 25 ← Pythagorean triplet
with adjacent = 7 and opposite = 24
Since position is in fourth quadrant then tanΘ < 0 , thus
tanΘ = - [tex]\frac{24}{7}[/tex]

Factor: 9x^2 + 6x + 12x + 8 *
please help me
Answer & Step-by-step explanation:
9x² + 6x + 12x + 8
First, simplify the expression.
9x² + 18x + 8
Now that you have simplified the expression, you can start factoring it. First, you have 9x². You can factor into 3x and 3x because 3 times 3 is 9 and once you multiply x by x, you will get x².
(3x + )(3x + )
Now that we have this part of the factoring, we have to find the other part. We can do this by looking at our constant number. Constant meaning a number that does not have a variable beside it. So, in this case, our constant is 8. We can reduce 8 into 2 and 4 because 2 times 4 is 8.
(3x + 2)(3x + 4)
So, the factored form of 9x² + 6x + 12x + 8 is (3x + 2)(3x + 4)

what is causation in a scatter plot
Answer:
A scatter plot displays data about two variables as a set of points in the x y x y x y -plane and is a useful tool for determining if there is a correlation between the variables. Causation means that one event causes another event to occur. Causation can only be determined from an appropriately designed experiment.
Step-by-step explanation:
Example: Correlation between Ice cream sales and sunglasses sold. ... Causation takes a step further than correlation. It says any change in the value of one variable will cause a change in the value of another variable, which means one variable makes other to happen. It is also referred as cause and effect.
Find the areas of the trapezoids.
Rotate it 90 degrees so that the would be the top.
Area of a trapezoid = (top+ bottom)/2 x height.
Each line on the graph is 2 units.
Top = 2
Bottom = 8
Height = 6
Area = (2+8)/2x6 = 30square units
The hexagon has all sides the same length and opposite sides are parallel, but is not a rhombus. Why?!
Although the sides are equal, it isn't a rhombus because there is 6 sides and not 4.
Find the value of x in the quadrilateral below.
Answer:
120
Step-by-step explanation:
The sum of the degrees in any quadrilateral is 360. So add up all of the degrees you know and subtract it from 360 to get your answer.
120 + 60 + 60 = 240
360 - 240 = 120
another way you know that's easier is the angles that are diagonal are equal to one another, so since x is diagonal to 120, it is equal to 120.

Find m ABC. Need help
Answer:
<ABC = 30°
Step-by-step explanation:
<ABC + <CBD = 90 [Complementary angles add up to 90°]
x+7+2x+14 = 90
3x + 21 = 90
3x = 90-21
3x = 69
Dividing both sides by 3
x = 23
Now
<ABC = 23+7
<ABC = 30°

ms kazenas has 4 pounds of cake mix which she discovers is only 25 of the cake mix she needs to make a whole cake how many more pounds of cake mix does ms kazenas need
Answer:
Step-by-step explanation:
entire cake = x
4 lbs of cake mix on hand = 25% of x
4 = 0.25x
x = 0.25/4
x = 16 lbs
She will need 16-4 = 12 lbs more
Lower quartile of 6 8 10 12 14 15 15 20
Answer: The lower quartile is 6
Step-by-step explanation: To find the lower quartile of a set of data, we can find the median of the data and then find the median of the first half. This strategy is similar to dividing a cake into halves, and then dividing one of the halves in half so that you end up with a quarter of the cake.
If a stack of 45 coins fits snugly in the coin wrapper shown, how thick is 1 coin?
coin
wrapper
d=21.17 mm V=28,470 mm
Answer:
1.797 mm
Step-by-step explanation:
The key to solving this problem is finding the length of the coin wrapper, or "height" of the cylinder.
The volume of a cylinder equation is:
V = hπr^2
- We want to find h
- We are given diameter and we will want the radius so we divide
21.17/2 = 10.585
r = 10.585
So to find h we manipulate the equation by dividing both sides by pi and r^2
resulting in the following:
h = [tex]\frac{V}{\pi r^2}[/tex]
now substitute given values and we get
h = [tex]\frac{28470}{\pi10.585^{2} }[/tex] = 80.883
Now to find the thickness of a single coin we divide the length of the sleeve (h) by the number of coins in the sleeve (45).
Thickness = 80.883/45 = 1.797 mm
Michael bought a stereo on sale for 20% off the regular price. The regular price of the stereo was $180. What was the sale price of the stereo?
Answer:
144

Take the original price and multiply by the discount
180* 20%
180 *.20
36
Subtract this from the original price
180-36 =144
The sale price is 144
Cards for Candy Two ladies played cards for candy; the winner received one piece per game from the loser. When it was time for one of the ladies to go home, one lady had won three games, while the other lady had a profit of three pieces of candy. How many individual games had they played?
Answer:
6 games
Step-by-step explanation:
if one lady had 3 pieces of candy, that means she must have gotten them from the other lady. And since the other lady had only won 3 games, that means that she must have lost an additional 3, so she had to give her candy to the other lady.
The number of individual games they played is 6 games.
How many games did they play?Given the cards for Candy two ladies played cards for candy; the winner received one piece per game from the loser. When it was time for one of the ladies to go home, one lady had won three games, while the other lady had a profit of three pieces of candy.
If one woman had three candies, it is obvious that she must have obtained them from the other woman. She had to give her candy to the other lady because she had only won three games, implying that she must have lost three more.
Therefore, the number of individual games they played is 6 games.

For which acute angle are the sine of the angle and cosine of the angle equal?
Answer:
∠45°
Step-by-step explanation:
When looking at a unit circle, the only acute angle (an angle between
0° and 90°) that consists of an equal sine and cosine is 45°. This is because:
[tex]sin 45 = \frac{\sqrt{2} }{2}[/tex]
[tex]cos45 = \frac{\sqrt{2} }{2}[/tex]
45° is the only acute angle that contains an equal sine and cosine.
Answer:
45 degrees
Step-by-step explanation:
Since Sin(90-x) = Cos(x), we can find that the angle at which 90-x=x is 45 degrees. This corresponds to [tex]\frac{\pi }{4}[/tex] radians

Step-by-step explanation:
x^2 -6x+y^2+4y-68 = 0
Complete the square
x^2 -6x+y^2+4y-68+68 = 0+68
x^2 -6x+y^2+4y = 68
Find the term to add for x
-6 /2 = -3 -3^2 = 9
Find the term to add for y

Answer:
Fatima's unit rate is 9.5 minutes per mile.
Step-by-step explanation:
To compute the one unit value of a variable divide the total values of n variables by n.
It is provided that it took Fatima 19 minutes to run 2 miles.
Then the unit rate at which Fatima runs is:
[tex]\text{Unit Rate}=\frac{19}{2}[/tex]
[tex]=9.5[/tex]
Thus, Fatima's unit rate is 9.5 minutes per mile.
Joshua owns a trucking company. For every truck that goes out, Joshua must pay the driver $25 per hour of driving and also has an expense of $2 per mile driven for gas and maintenance. On one particular day, the driver drove an average of 50 miles per hour and Joshua's total expenses for the driver, gas and truck maintenance were $625. Write a system of equations that could be used to determine the number of hours the driver worked and the number of miles the truck drove. Define the variables that you use to write the system.
Let h= the number of hours the driver drove
Let m= the number of miles driven
25h+2m=625
m=50h
System of equations are 25x + 2y = 625 and y = 50x
Where x represents number of hour of driving and y represent number of mile driven for gas and maintenance.
Since, Joshua pay the driver $25 per hour of driving
So for x hours pay $ 25x
And also has an expense of $2 per mile driven for gas and maintenance
So for y miles pay $ 2y
Thus, for the driver drove an average of 50 miles per hour
Equation is, y = 50 x
And since, Joshua's total expenses for the driver, gas and truck maintenance were $625.
So equation is, 25x + 2y = 625
