Answer:
c=0
Step-by-step explanation:
15 = 80% * x
15 = 80/100 * x
15 = 8/10 * x
x = 15 * 10/8
x = 150/8
x = 18.75
<span>80% of 18.75 is </span>15<span>.</span>
Answer:
Step-by-step explanation:
The altitude to the hypotenuse of a right triangle create two smaller triangles, all of which are similar to the original. This means corresponding sides are proportional.
3. Using the above relationship, ...
short-side/hypotenuse = 8/y = y/(8+23)
y^2 = 8·31
y = 2√62
__
long-side/hypotenuse = z/(8+23) = 23/z
z^2 = 23·31
z = √713
__
short-side/long-side = 8/x = x/23
x^2 = 8·23
x = 2√46
_____
4. The picture is fuzzy, but we think the lengths are 25 and 5. If they're something else, use the appropriate numbers. Using the same relations we used for problem 3,
y = √(5·25) = 5√5 . . . . . . . = √(short segment × hypotenuse)
z = √(20·25) = 10√5 . . . . . = √(long segment × hypotenuse)
x = √(5·20) = 10 . . . . . . . . . = √(short segment × long segment)
Step-by-step explanation:
Length (L) = 2 cm
Breadth (b) = 2 / 3 cm
Area of the rectangle
= L * b
= 2 * 2/3
= 4/3 cm²

Answer:
commutative property of multiplication
Step-by-step explanation:
The value of the product of the given equation remain the same while the order is reversed
The number sequence 4 × 6 = 6 × 4 is an example of the commutative property of multiplication
Reason:
The given number sentence is 4 × 6 = 6 × 4
Required: The property the number sentence is an example of (represent)
Solution:
The difference between the left and right expression is that the order of the
values being multiplied is changed or reversed (commute)
Therefore, the number sentence states that the value of the multiplication
of two variables remain equal when the places of variables are
interchanged as follows; a × b = b × a
a × b = b × a is an example of commutative property of multiplication
Therefore;
4 × 6 = 6 × 4 is an example of the commutative property of multiplication
