Answer: (-19/80, -1/2)
Step By Step Explanation:
First you want to do 2/5 - 7/8. Once you get -19/40, you want to divide it by 2. After doing this step, you will get -19/80. Next, you want to do the same thing with the other one. -2/5 -3/5 or 2/5+3/5 except the answer will be negative. Now you get -1/2. Therefore, the answer is (-19/80, -1/2). Sorry if my explanation is trashy.
I think that would be 100 million pounds of coal.
Answer:
Average cost per ball: $22.2
Step-by-step explanation:
Cost per ball: $22
Cost of 300 balls: 300 × 22 = $6600
Total No. of Orders: 3
Delivery fee per order: $20
Total Delievery fee: 20 × 3 =$60
Total cost including delivery cost: $6600 + $60 = $6660



<u><em>Note: It seems you may have unintentionally missed to add the complete question statement, but I will make sure to make you understand the concept of angle congruence anyways using which you may be able to clear all your queries regarding the concept.</em></u>
Answer:
When we say the angles Y and B are Congruent. It means these congruent angles have the same angle measured in degrees. (or in radians as both are units of measure for angles).
The figure a is also attached below to visualize the concept.
Step-by-step explanation:
When we say the angles Y and B are Congruent. It means these congruent angles have the same angle measured in degrees. (or in radians as both are units of measure for angles).
Here are some additional things to observe:
- Angles are congruent as long as the angles are the same
- they don't have to point in the same direction
- they don't have to be made with lines of the same length.
For instance, below is the example. Where,
As the measure of these angles is same. It means the angles Y and B are Congruent. The figure a is also attached below to visualize the concept.

Answer:
Step-by-step explanation:
the perimeter of the semi-circle would be the diameter plus the circumference of half of the circle.
They want to know the perimeter of a square using the diameter of the sem-circle as ONE side, so the perimeter of the square would be 4 times the ONE side.
We should recall:
diameter = 2 times the radius circumference of a cirlce = 2π r
How do we find the diameter of the of the semi circle?
The perimeter of the semi circle is given as 108 cm
Perimeter of the semicirle = 2r + π r diameter plus semi circumference
108 = r ( 2 + π) factor out the r and solve for r
108 / (2 + π) = r divide both sides by ( 2 + r)
Now we know r, the perimeter of the squqre is 4 times 2r or 8r
perimeter of square = 8 [ 108 / (2 + π) ] π I used 3.14
= 864 / 5.14
= 168.1 cm I got rounded to nearest tenth
