Explanation:
25% = 25/100 = 0.25
25% of 84 = 0.25*84 = 21
So 21 cm has been cut off, leaving 84-21 = 63 cm left over
Or you could say that if 25% has been cut off, then 75% of the stick remains
So, 75% of 84 = 0.75*84 = 63 cm remains.
The remaining length of 63 cm is cut into 6 equal pieces
Each smaller piece is 63/6 = 10.5 cm long

solve the equation
2(h-8) - h=h - 16
A h = 8
B h= -8
C h = infinitely many solutions
D h = no solution
Answer:
2(h-8)-h=h-16
2(h-8)=h+h-16
2(h-8)=2h-16
2(h-8)=2(h-8)
h-8=h-8
h-h=8-8
0=0 so their can be infinite value of h.
hence c is correct
we can put in place of anything but answer will be zero.
Answer:
C h= infinitely many solutions
Step-by-step explanation:
when you replace h with any number it is true
say h= 3
2(3-8) - h = h-16
2(-5) - 3 = 3 - 16
-10 - 3 = -13
-13 = -13
using distributive property:
2h-16-h = h-16
combine like terms
h-16=h-16
it is the same expression on both sides of the equal sign
hope that helps!

Answer:
the answer is 2.
Step-by-step explanation:
How do I know this? well, those red arrows on the line show that those 2 sides (ED) and (AB) are congruent which means they are equal. therefore if they are equal and we know ED is 2, then we know AB is also 2. Hope this helped :)

Answer:
2.89 m
Step-by-step explanation:
The attached shows the figure drawn accurately. It also shows that the angle of the line of sight is 102° -90° = 12° below the horizontal. The sine relation is useful in this situation.
The side opposite the angle in the triangle of interest is the difference in building heights, 5.3 -4.7 = 0.6 m. So, the useful relation is ...
Sin = Opposite/Hypotenuse
sin(12°) = (0.6 m)/(PR)
PR = (0.6 m)/sin(12°) ≈ 2.886 m
PR ≈ 2.89 m
The distance to the subject is about 2.89 meters.

A compound is made up of various elements totaling 90 ounces. If the total amount of uranium in the compound weighs 18 ounces, what percent of the compound is made up of uranium? If necessary, round your answer to the nearest hundredth.
Answer:
20%
Step-by-step explanation:
The percent of the compound that is made of uranium is calculated as:
(Number of ounces of uranium /Number of ounces of the compound)
× 100
Total amount of uranium in the compound weighs = 18 ounces
A compound is made up of various elements totaling = 90 ounces.
Hence:
= 18/90 × 100
= 1800/90
= 20%
Therefore, the percent of the compound that is made up of uranium is 20%

Step-by-step explanation:
The product 55 x 25 equaled to 1375
What is Multiplication?Multiplication is a method of finding the product of two or more numbers
55 x 25 is equal to 1,375.
To calculate this product, we can multiply the units digit (5) of the two numbers and write it as the units digit of the result.
Then, we multiply the tens digit (5) of 55 by 25 and add any carry-over from the previous step (0) to get the tens digit of the result.

Solve the following inequality. 36> -2(x+4)+14
Answer:
x > - 15
Step-by-step explanation:
Given
36 > - 2(x + 4) + 14 ← distribute and simplify right side
36 > - 2x - 8 + 14
36 > - 2x + 6 ( add 2x to both sides )
2x + 36 > 6 ( subtract 36 from both sides )
2x > - 30 ( divide both sides by 2 )
x > - 15

Two given angles cannot be both..
A. congruent and complementary
B. vertical and congruent
C. adjacent and congruent
D. vertical and adjacent
Please help me :(
If vertical angles are directly opposite each other and do not share a common side, therefore, two given angles cannot be both: D. vertical and adjacent.
Recall:
If two angles are said to be vertical when both angles are directly opposite each other and are also congruent or equal in measure.
Vertical angles share a common vertex or point but do not share a common side.
Adjacent angles share a vertex and a common side.
Thus, if vertical angles are directly opposite each other and do not share a common side, therefore, two given angles cannot be both: D. vertical and adjacent.
