Answer:
29°61°Step-by-step explanation:
Complementary angles are two angles that add up to be 90 degrees.
We can write an equation and solve for x.
(3x - 4) + (5x + 6) = 90
~Combine like terms
8x + 2 = 90
~Subtract 2 to both sides
8x = 88
~Divide 8 to both sides
x = 11
Angle DEF:
3x − 4
3(11) - 4
33 - 4
29°
Angle FEG:
5x + 6
5(11) + 6
55 + 6
61°
Check:
29 + 61 = 90°
Best of Luck!

In trapezoid EFGH, EF¯¯¯¯¯ and HG¯¯¯¯¯¯ are the bases. Point J is the midpoint of EH¯¯¯¯¯¯ and point K is the midpoint of FG¯¯¯¯¯ . EF=3x+2 , HG=7x−2 , and JK=15 .
What is the value of x?
Answer:
6
Step-by-step explanation:
The required value of x is 3 for the given trapezoid.
What is a trapezoid?A trapezoid is a quadrilateral having two parallel bases and one set of other sides called as legs.
Given that EF and HG are the bases and J and K are the midpoints of the legs, we can use the midsegment theorem which states that:
The segment connecting the midpoints of the legs of a trapezoid is parallel to the bases and is equal to half the length of the bases.
We can use this theorem to write the equation:
JK = (EF+HG)/2
Now we are given that:
EF=3x+2 , HG=7x−2 , and JK=15
So we can substitute these values in the equation:
15 = (3x+2+7x-2)/2
15 = (10x)/2
15 = 5x
x = 3
Thus, the required value of x is 3.

When playing a track on the outer edge, a CD rotates 300 times per
minute. Through how many degrees does it rotate in one second?
Answer:
I think it's 1800 Degress
Step-by-step explanation:
If the CD rotates 300 times per minute, we know that equals 300 rotations/60 seconds
That ends up being 5 rotations per second.
Since we know that a full rotation is 360 degrees, then it should equal 1800 degrees.
Hope that helps, let me know if this does or not.

Point A is located at negative 4 over 6 and point B is located at negative 1 over 6. What is the distance between points A and B?
negative 4 over 6 minus negative 1 over 6 = negative 3 over 6; therefore, the distance from A to B is absolute value of negative 3 over 6 equals negative 3 over 6 units
negative 4 over 6 minus negative 1 over 6 = negative 3 over 6; therefore, the distance from A to B is absolute value of negative 3 over 6 equals 3 over 6 units
negative 4 over 6 plus negative 1 over 6 = negative 5 over 6; therefore, the distance from A to B is absolute value of negative 5 over 6 equals 5 over 6 units
negative 4 over 6 plus negative 1 over 6 = negative 5 over 6; therefore, the distance from A to B is absolute value of negative 5 over 6 equals negative 5 over 6 units

Question 3 What is the slope of the line that passes through the points (0.-7) and (-4, 3)? 0 -3/11 O -2/5 À O -5/2 0 10/4 Question 4
Answer:
Gradient = Change in y / Change in x
Gradient = (-7-3) / (0-4)
Gradient = -10/-4
Gradient = 2.5
So the answer is 10/4, which is 2.5
The slope of the line passes through the points (0.-7) and (-4, 3) is -5/2. The correct option is B.
What is a slope?Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope is defined as the ratio of the rise to the run.
Given that the points are (0.-7) and (-4, 3). the slope of the line will be calculated as,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = ( 3 - (-7) / ( -4 - 0 )
Slope = 10 / -4
Slope = -5 / 2

9514 1404 393
Answer:
y = 2/3x -23/3
Step-by-step explanation:
In a version of point-slope form this is ...
y = m(x -h) +k . . . . . line with slope m through point (h, k)
Expanding this, we have ...
y = mx +(k -mh) . . . . slope-intercept form
For the given point and slope, the equation is ...
y = 2/3x +9 -2/3(2)
y = 2/3x -23/3

At a local pumpkin patch you can pick your own pumpkins. There is a $5 charge to enter the patch and then a $0.25 charge per pound of pumpkin. Let p
represent the weight of the pumpkin you choose and C(p)
represent the total cost of the pumpkin in terms of the weight of the pumpkin. Equation, in function notation:
Answer:
C(p) = 0.25p + 5
Step-by-step explanation:
$5 is the amount of money you have to pay when you don't get a pumpkin (a pumpkin that's 0 lbs), so the y-intercept is 5. 0.25 is the rate at which the price increases as the weight increases, so the slope is 0.25.
m = slope, b = y-intercept
C(p) = mp + b
C(p) = 0.25p + 5
In last weekend's track meet, Lakeland High School had 30 individual-
event placers score a total of 111 points. First-place finishers score 7 points, second-place finishers score 4 points, and third-place finishers score
1 point. The number of first- and second-place finishers was twice the
number of third-place finishers. Find the number of runners that finished in
each place.
Answer:
The number of runners that finished in first place , second place and third place are 7 , 13 and 10 respectively.
Step-by-step explanation:
Let the no. of runners fished at first place be x
Let the no. of runners fished at second place be y
Let the no. of runners fished at third place be z
We are given that Lakeland High School had 30 individual- event placers
So, x+y+z=30 -----1
First-place finishers score 7 points
So, Total score of x runners = 7x
Second-place finishers score 4 points
So, total score of y runners = 4y
Third-place finishers score 1 point.
So, total score of z runners = z
We are given that 30 individual- event placers score a total of 111 points
So, 7x+4y+z=111 ----2
We are also given that The number of first- and second-place finishers was twice the number of third-place finishers.
x+y=2z ---3
Substitute the value from 3 in 1
x+y+z=30
2z+z=30
z=10
Substitute the value of z in 1 and 2
x+y=20 ----4 and 7x+4y=101 ---5
Substitute the value of x from 4 in 5
7(20-y)+4y=101
140-7y+4y=101
140-3y=101
39=3y
`13=y
Substitute the value of y and z in 1
x+13+10=30
x=7
Hence the number of runners that finished in first place , second place and third place are 7 , 13 and 10 respectively.

10x-6y=-48
standard to slope intercept form
Answer:
[tex]y=\frac{5}{3}x+8[/tex]
Step-by-step explanation:
Remember, slope intercept form is:
y = mx + b
where m is the slope and b is the y-intercept.
To get the given equation into slope-intercept form, we would have to first solve for y in terms of x.
10x - 6y = -48
Subtract 10x from both sides.
-6y = -48 - 10x
Multiply both sides by -1.
6y = 10x + 48
Divide both sides by 6.
[tex]y=\frac{5}{3}x+8[/tex]
And now, looking at the equation that we found and the equation for slope-intercept form, we can see that we have found the equation for 10x - 6y = -48 in slope-intercept form.

---- = ----
100 x
So you cross multiply which would give you 30x = 1500, then you divide by 30 on both sides leaving you with 50. If you want to check it, you can then multiply 50 by .30 which would give you 15.

Answer:
p = 6
Step-by-step explanation:
I'm omitting the x since you cannot have 2 unknowns.
(15 + 17 + 19 + 20 + p +23) /5 = 20 Combine the left
(94 + p) / 5 = 20 Multiply both sides by 5
94 + p = 20 * 5
94 + p = 100 Subtract 94
P = 100 - 94
P = 6
