Volume=16^3



Volume=4096

Answer:

16^3

Step-by-step explanation:

A change from 20 to 25 represents a positive change (increase) of 25% Percent change = [(20 - 25) / 20] x 100 = 25 % (increase)Where: 20 is the old value and 25 is the new value. In this case we have a positive change (increase) of 25 percent because the new value is greater than the old value.

Hope this helps :)

percent change=100 times change/original
change=new-origianl

change=25-20=5
original=20

percent change=100 times 5/20-500/20=25
answer is 25% change

Percentages are easy to represent as decimals. Just remember this: If the value is under 100%, just place a decimal point in front of the percent value and remove the percentage sign. If it's over 100%, you'd put the decimal after whatever is in the hundreds place. The reason you can do this is because percent represents a value out of one hundred, and decimals do the same representing values as part of one.
So, 39%->.39

Explanation:
_________________
2)  "Solve: | m + 8| = 16 ";  Assuming we are to solve for "m"; we would use:
____________
"Case 1" and "Case 2" scenarios;
_______________
 since we need to find the value for "m" when:
__________________
Case 1:   (m + 8) = 16; AND:
_____________
Case 2:  - (m + 8) = 16 .
_________________
→ Let's solve, starting with Case 1:
_____________________
m + 8 = 16;  → Subtract "8" from EACH SIDE of the equation;
_____________________
→ m + 8 − 8 = 16 − 8 ; →  To get: →  m = 8
______________
→ Let us solve for "Case 2" :
____________
- (m + 8) = 16 ;
__________________________
Note the distributive property of multiplication:
_____________________
→ a*(b + c) = ab + ac ;
___________________________
→ As such: - (m + 8) = 16 ;
____________________________
Consider this equation as:
_____________________
- 1(m + 8) = 16 ;
_______________________
→ Note the  "-1" is implied, since anything multiplied by "1" is that same thing. The "negative" in the "negative 1" comes from the "negative sign" already present.
_________________________
→  - 1(m + 8) = 16 ;   →  (-1*m) + (-1*8) = 16 ; 

→  -1m + (-8) = 16 ; →  Rewrite as: -1m − 8 = 16 ; 
_______________
→ Add "8" to EACH SIDE of the equation ; →  -1m − 8 + 8 = 16 + 8 ;
→  to get: -1m = 24 ;
________________
→ Divide EACH SIDE of the equation by "-1"; to isolate "m" on one side of the equation; & to solve for "m" ;  →  -1m / -1 = 24 / -1 ; → m = -24
_____________
So we have: m = 8; and m = -24 ; which is: "Answer choice: [A]: {-24, 8}" .
_____________________
3) Given: |2n - 3| = 5 ; Solve for "n" ; 
_______________
Case 1:  2n − 3 = 5 ; 
_______________
→ Add "3" to EACH side of the equation;  2n − 3 + 3 = 5 + 3 ; → 2n = 8 ; 
    →  Now, divide EACH SIDE of the equation by "2"; to isolate "n" on one side of the equation; and to solve for "n";     → 2n / 2 = 8 / 2 ;  → n = 4 .
__________
Case 2: - (2n − 3) = 5 ;
_________________
Simplify: - (2n − 3);  → - 1(2n − 3)  = (-1*2n) − (-1*3) = -2n − (-3) = -2n + 3 ;
_________________
→ Rewrite the equation, "- (2n − 3) = 5 " ;  as:
→  -2n + 3 = 5;   → Now, subtract "3" from EACH side of the equation:
→  -2n + 3 − 3 = 5 − 3 ; → -2n = 2 ;
_____________
→ Divide EACH SIDE of the equation by "-2"; to isolate "n" on one side of the equation; and to solve for "n" ;  → -2n / -2 = 2 / -2 ; → n = -1 . 
→ So, n = 4, AND -1; which is: Answer choice: [C]:  {-1, 4} .
__________________________
4)  Given: |x/3 + 1| = 6 ; Solve for "x";
____________
Case 1: (x/3) + 1 = 6; Subtract "1" from EACH side of the equation;
 _______________
→ (x/3) + 1 − 1 = 6 − 1 ; → (x/3) = 5 ; → x = 5*3 = 15
 _____________
Case 2:  - [ (x/3) + 1] = 6;  → -1 [(x/3) + 1] = 6 ; → [-1*(x/3) ] + (-1*1) = 6 ;  
______________
→   - (x/3) + (-1) = 6 ;  →  - (x/3) − 1 = 6 ; 
→ Add "1" to EACH side of the equation:  
→ - (x/3) − 1 + 1 = 6 + 1 ;  →  - (x/3) − 1 + 1 = 6 + 1 ; 
   →  - (x/3) = 7 ↔  -x / 3 = 7;  -1x = 7*3 ; →  -1x = 21;
____________
→ Divide EACH SIDE of the equation by "-1"; to isolate "x" on one side of the equation; & to solve for "x" ;
____________
→ -1x / -1 = 21 / -1 ; → x = -21;  
So, x = 15, AND -21; which is:  Answer choice: [A]:  {-21, 15} .
_____________
5)  Given: |2 − 3x| = 7 ; Solve for "x"; 
__________
Case 1:  (2 − 3x) = 7
______________
Given: 2 − 3x = 7 ;  → Subtract "2" from EACH side of the equation;
______________
→ 2 − 3x − 2 = 7 − 2 ; → to get: -3x = 5 ; 
____________
→ Now, divide EACH side of the equation by "-3"; to isolate "x" on one side of the equation; and to solve for "x" ;   →  -3x / =3 = 5/ -3  = - (5/3).
________
→Case 2:  -(2 − 3x) = 7 ; Simplify,
________________________
Note: The distributive property of multiplication:
 → a*(b + c) = ab + ac ; AND:  → a*(b − c) = ab − ac ;
__________
→  - (2 − 3x) = 7 ; →  -1(2 − 3x) = 7 ;  → (-1*2) − (-1*3x) = 7 ;
_________
→  - 2 − (-3x) = 7 ; → - 2 + 3x = 7 ; → Add "2" to EACH side of the equation ;
→  - 2 + 3x + 2 = 7 + 2 ;  → 3x = 9 ; 
____
→ Now, divide EACH side of the equation by "3"; to isolate "x" on one side of the equation; and to solve for "x" ;   →  3x / 3 = 9 / 3 ;  x = 3; 
_____
So, x = - 5/3; AND 3;  which is: Answer choice: [C]: {-5/3, 3} .

What is Right Angle Triangle?

A right triangle or right-angled triangle, or more technically an orthogonal triangle, historically known as a rectangled triangle, is a triangle with one right angle (that is, a 90-degree angle) and two perpendicular sides. Trigonometry is founded on the relationship between the sides and other angles of a right triangle.

Solution:

According to the Question,

Let, Base = x and Height = y

x = 7 + y

Using the Pythagorous Theorem

a^2 + b^2 = c^2

Final answer:

To determine how many 3/4 are in 7/8, you would divide the first fraction by the second, which involves multiplying 7/8 by the reciprocal of 3/4 (which is 4/3), resulting in approximately 1.17.

Explanation:

To find out how many 3/4 are in 7/8, you have to divide 7/8 by 3/4. Division in fractions requires the multiplication of the first fraction by the reciprocal of the second fraction.

So, the reciprocal of 3/4 is 4/3. Now, you multiply 7/8 by 4/3 to get:

(7/8) * (4/3) = 7*4 / 8*3 = 28/24

Simplify the fraction 28/24 by dividing both numbers by their greatest common divisor, which is 4, resulting in the fraction 7/6.

The length is 15 cm.  The width is 3/5 of that.
15/5 = 3
3 x 3= 9. 9 cm is the width.
Perimeter: 15(2) + 9(2) = 48 cm
Area: 15(9) = 135 cm

The area of the rectangle is 135 [tex]cm^{2}[/tex], and the perimeter is 48 cm, given that the width is 3 / 5 of the rectangle's length which is 15 cm.

To find the area and perimeter of a rectangle where the width is 3/5 of the length, we apply the formulas. First, calculate the width:

Width = 3 / 5 × Length

Width = 3 / 5 × 15

Width = 9 cm

Now, calculate the area:

Area = Length × Width

Area = 15 cm × 9 cm

Area = 135 cm²

Next, calculate the perimeter:

Perimeter = 2 x (Length + Width)

Perimeter = 2 x (15 cm + 9 cm) = 2 x (24 cm)

Perimeter = 48 cm

The area of the rectangle is 135 cm2, and the perimeter is 48 cm.
