if DF = 15 and DE = 6, find EF if E is between D and F?
Answer:
EF=9
Step-by-step explanation:
DF=15
DE=6 EF=9
Write equation 6+x=15
subtract 6 on both sides
x=9 EF=9

Answer:
3) Y = -1.5
Step-by-step explanation:
7=-2y+4
We move all terms to the left:
7-(-2y+4)=0
We get rid of parentheses
2y-4+7=0
We add all the numbers together, and all the variables
2y+3=0
We move all terms containing y to the left, all other terms to the right
2y=-3
y=-3/2
y=-1+1/2
. Bartholomew Jackson is paid $10.56 an hour to knit dog sweaters. He gets paid 1.5 times his normal wages for overtime (over 40 hours per week). If he works 55.5 hours in one week, how much money does he earn
Answer:
$667.92
Step-by-step explanation:
Use the equation (p*1.5)*o=t
the variable p is equal to his hourly pay.
the variable o is equal to hours worked overtime.
the variable t is equal to the total amount of money they will make.
As for the 1.5, this is the way overtime is always calculated, at 1.5 times the rate of your hourly wage.
Back to the question:
the variable p is replaced by his hourly pay, $10.56.
the variable o is replaced by the amount of hours he worked overtime. Now, this part is a bit trickier because the question is designed to confuse you. If his overtime only counts if he works over 40 hours a week, then you need to subtract the 40 from his total amount of hours worked. You should get 15.5 because 55.5-40=15.5. Thus, variable o=15.5.
Lastly, you have to calculate it.
Plug in the variables to get:
($10.56*1.5)*15.5= $245.52
DON'T STOP HERE!!!
Since the question asks for how much he has earned for the week, you have to add this onto his normal salary. This part is easy, just multiply the 40 hours by his pay. So,
40*$10.56= $422.40.
Finally, add the overtime ($245.52) to his normal pay ($422.40).
$422.40+$245.52= $667.92

a clock is circular in shape with diameter of 25 cm. find the length of the arc between the markings 12 and 5 rounded to the nearest tenth cm
Answer:
32.7 cm
Step-by-step explanation:
For central angle θ in radians, the arc length is given by ...
s = rθ
The angle between 12 and 5 is 5π/6 radians, and the radius is 25/2 cm, so the arc length is ...
s = (25/2 cm)(5π/6) = (125/12)π cm ≈ 32.7 cm
The arc length between the markings is about 32.7 cm.

Step-by-step explanation:
Jaiden is ordering 2.615, 2.65, 2.7, and 2.623 from least to greatest. Here are his steps: (1) Compare and order 2.7 and 2.65 because they have the fewest digits. (2) Compare each digit of the numbers 2.615 and 2.623. * The units digits are equal. * The tenths digits are equal. * 1 < 2 in the hundredths place so 2.615 < 2.623. (3) Combine the two lists into one: 2.7, 2.65, 2.615, 2.623. Which statement describes Jaiden’s error?
Hurry pleaseeee
Answer: D
Jaiden should have added zeroes to the ends of the shorter decimals to get 2.615 etc
Step-by-step explanation:
The numbers that have the same unit value but different digits in the decimal place can be ordered using place value.
The statement that describes Jaden's error is; Jaiden should have added
zeros to each of the shorter decimals to get 2.615, 2.650, 2.700, and 2.623,
then he should have compared them using place values.
Reasons:
The steps are;
(1) Comparing the digits to select the ones with the least amount of digits
(2) Comparing the digits in the place values of the numbers that equal number of digits
(3) Combining the list of the above comparison into one
Required:
To select the statement that describes Jaiden's error.
Solution:
The place value indicates the multiple of 10 by which the digit is multiplied. The given numbers have the same values in the ones place value, the difference are in the numbers to the right of the decimal point.
The given numbers are;
2.615
2.65
2.7
2.623
The steps to order the numbers from least to greatest;
Add zeros to the shorter decimals such that each number have the same number of digits after the decimal point; 2.615, 2.650, 2.700 2.623Then
Select the number with the lowest ones; Which gives all the numbersThen
From the above list, select the number with the lowest tenth, and move them to the left of the list; Which gives the numbers, 2.615, 2.650, 2.623, 2.700Next
From the above list, select the number with the lowest hundredth, and move them to the left of the list, in increasing order of the hundredth; Which gives the numbers, 2.615, 2.623, 2.650, 2.700The numbers 2.615, 2.623,2.650, 2.700, are in the order from least to
greatest.
Therefore Jaiden's error is that Jaiden should have added zeros to each of
the shorter decimals to get 2.615, 2.650, 2.700, and 2.623, then he should
have compared them using place values.

At noon, a ship is at the midpoint of the segment connecting the buoy and the lighthouse on the grid. Find the coordinates that best represent the ship's position at noon?
Answer:
[tex] (\frac{1}{2}, 2) [/tex]
Step-by-step explanation:
Using the midpoint formula, [tex] M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}) [/tex], we can find the coordinates that represents the position of the ship at noon.
Let [tex] L(-4, 7) = (x_1, y_1) [/tex] (given on the coordinate plane)
[tex] B(5, -3) = (x_2, y_2) [/tex] (given also)
Plug in the values into the formula and solve as follows:

Without solving, determine whether the equation has one solution, no solution, or infinitely many solutions. 6x+6=6(x+1)
Answer:
Infinite Solutions
Step-by-step explanation:
6x+6=6(x+1)
6x+6=6x+6
If both sides of the equations are equal, it will ALWAYS be infinite solutions:)
Answer:
Infinite solutions.
Step-by-step explanation:
You have to distribute the 6 to the x and the 1. You'll then realize that both sides have 6x+6, and since 6x-6x=0 and 6-6=0, If you solve this your answer would be 0=0 this means the problem has an infinite number of solutions.

6. The amount of time it took four soccer players to run from one goal line to the other is as follows:
Player #1 - 10.4 seconds
Player #2 - 10.1 seconds
Player #3 - 9.9 seconds
Player #4 - 9.4 seconds.
If the data was only accurate to the ones place, which soccer player's time would be different from the others?
A Player #1
B Player #3
C Player #2
D Player #4
Given:
The amount of time it took four soccer players to run from one goal line to the other is:
Player #1 - 10.4 seconds
Player #2 - 10.1 seconds
Player #3 - 9.9 seconds
Player #4 - 9.4 seconds
To find:
Soccer player whose time would be different from the others, if the data was only accurate to the ones place.
Solution:
We need to approximate the time to the ones place.
Player #1 - 10.4 seconds = 10 seconds
Player #2 - 10.1 seconds = 10 seconds
Player #3 - 9.9 seconds = 10 seconds
Player #4 - 9.4 seconds = 9 seconds
Therefore, the time of players 4 is different from others.
Hence, the correct option is D.
1) Find the value of X if m < EDG= 112 degrees
Answer:
x = 12
Step-by-step explanation:
From the question given above, the following data were obtained:
m < EDG = 112°
m < EDH = 6x – 9
m < HDG = 4x + 1
x =.?
Thus, we can obtain the value of x as shown below:
m < EDG = m < EDH + m < HDG
112 = 6x – 9 + 4x + 1
112 = 6x + 4x – 9 + 1
112 = 10x – 8
Collect like terms
112 + 8 = 10x
120 = 10x
Divide both side by 10
x = 120/10
x = 12
Therefore, the value of x is 12.

9/2x = 15/36
9 * 36 = 15 * 2x
324 = 30x
x = 324/30 = 10 8/10 = 10 4/5
