Answer:
A. 7
Step-by-step explanation:
We already know that 8+4 = 12, So now we have to find out how to make the equation equal 12.
2×6= 12, we have to find out what x will be in order to make the equation true.
2(7-1) = 2(6) = 12. Substitute the 7 for x.
x = 7
Solve for x. 4x^2 - 48x + 144 = 0
Step 2: Radii OK and NL are perpendicular to OM because of the radius-tangent theorem. By definition of perpendicular, angles KOM and LNM are right angles. This means that triangles KOM and LNM are right triangles. Angle LMN is common to both right triangles, so by the _________________________, triangles KOM and LNM are similar. please fill in the blank
Answer:
AAA postulate.Step-by-step explanation:
Givens
Angles KOM and LNM are congruent, because both are right.Angle LNM is common to both triangles.If two internal angles of two triangles are congruent, then the third angle is also congruent.
Therefore, the similarity is proven by AAA postulate, which states that if we have three corresponding angles congruent, then those triangles are similar.
Remember that similarity is about proportion between sides and congruence between angles.

1325.5
im not too sure, but i think that is the answer.
Answer:
Area = 2 x Sqrt (2) x r^2
Area = 2 x sqrt(2) x 20^2
Area = 2 x 1.414 x 400
Area = 1131.37

what is between 1/6 and 2/6 on a number line
Answer:
3/12 or 1/4
Step-by-step explanation:
To find what is between, we have to use the formula:
x + y= z
z/2 = midpoint!
So, we can do that with this number.
1/6 + 2/6 = 3/6. We could simplify it, but let’s keep it at 3/6
3/6 divided by 2 = 3/6 · 1/2 = 3/12
So, the midpoint would be 3/12.
Mr. Wilson bought a bag of bird seed and put half of it in the bird feeder.He split the other half equally among his 4 parrot birds how much of the bag did each pet bird eat
Answer:
Each parrot Bird ate 1/8 of a bag
Step-by-step explanation:
Here, we are interested in calculating the portion of the bag eaten by each of the pet birds
Firstly, we know he put 1/2 in the feeder, the amount not put in the feeder = 1-1/2 = 1/2 bag
Now this 1/2 bag was shared amongst 4 parrot birds, amount eaten by each of the parrot birds = 1/2 divided by 4 = 1/8 of the bag

Chara sold 52 boxes of candy for her marching band fundraiser. The large box costs $3.50 each and the small box costs $1.75 each. If Chara sold $112 worth of candy, how many boxes of each size did she sell?
Answer:
The number of boxes of candy sold are:
40 small boxes and
12 large boxes of candy.
Step-by-step explanation:
Let the number of small boxes sold = x
Let the number of large boxes sold = y
we are given the following information:
x + y = 52 - - - - - -(1) (Chara sold 52 boxes of candy)
3.5(y) + 1.75(x) = 112 - - - - - - (2) (Chara sold $112 worth of candy)
From the two equations above, x and y can be solved as follows:
x + y = 52 - - - - - -(1)
x = 52 - y - - - - - - (3)
putting the value if x in equation (3) to replace x in equation (2);
3.5(y) + 1.75(x) = 112 - - - - - - (2)
3.5(y) + 1.75(52 - y) = 112
3.5y + 91 - 1.75y = 112
(3.5y - 1.75y) + 91 = 112
1.75y = 112 - 91 = 21
y = 21 ÷ 1.75 = 12
y = 12
Now, let us put the value of y into equation (3)
x = 52 - y - - - - - - (3)
x = 52 - 12 = 40
Therefore,
40 small boxes and 12 large boxes of candy were sold.

Matt measures 3 pieces of string. The first piece is 544 centimeters. The second piece is 144 centimeters, and the thrill piece is 112 centimeters. How many meters of string does he have altogether?
Add all the strings together.
544 + 144 + 112 = 800
Conversion: 100cm = 1m
Divide.
800 / 100 = 8
Therefore, Matt has 8 meters of string altogether.

Question :
The triangular prism shown below is 6 cm wide and 4 cm deep. The vertical height is 7 cm. What is the length of the side edge, s, of the triangular prism? Round your answer to the nearest tenth.
Answer: 7.62cm
Step-by-step explanation:
Given the following :
Width = 6cm
Depth = 4cm
Vertical height = 7cm
Splitting the face of the prism into two:
Thus the width becoming 6cm/2 = 3cm and vertical height = 7cm
Using Pythagoras ;
The side edge 's' equals
s^2 = width^2 + height^2
s = √(width^2 + height^2)
s = √(3^2 + 7^2
s = √9 + 49
s = √58
s = 7.62cm

Drawing a time line that shows 9:00, and then counting backward 5 minutes at a time until you get to 5 minutes. Then count backward 1 more minute(s) for a total elapsed time of ____ minutes.
Answer:
54 minutes
Step-by-step explanation:
The elapsed time typically refers to the amount of time spent from the beginning of an event to the end of such event. Now id we have a time line; that shows 9:00; then if we count backward 5 minutes ; we have 55 more minutes for an hour to run out. Then we then count another 1 more minutes, leaving us with 54 minutes. The 54 minutes remaining is said to be our total elapsed time.
i.e 9:00 - (5 + 1) minutes
8:54 (8 hours 54 minutes)
Hence; 54 minutes remaining is said to be our total elapsed time.
