Answer: The second one, 10 rolls for $12. 1.29 (Rounded)
Step-by-step explanation:
14/18 is 1.29 (Rounded)
10/12 is 1.20.
The unit rate is cheaper, therefore making it the better buy
Answer:
Similar states:
- They have the same geometric shape.
- Their corresponding sides are in proportion.
Given the statement: Pentagon JKLMN is similar to pentagon STUVW .
If NJ = 4 units WS = 3 units and JK = 5 units.
We have to find ST.
By definition of similar;
.
then;
Substitute the given values, to solve for ST;
By cross multiply we have;
Divide both sides by 4 we get;
Therefore, the value of ST = 3.75 units
Plug in 4 for l, 6 for w, and 7 for h
V = (1/3)(4)(6)(7)
Multiply the terms together
V = (1/3)(168)
Note that when multiplying 1/3 with 168, you are really dividing by 3
V = 168/3
V = 56
B) 56 cu. in is your answer
hope this helps
The expression (5³)⁹÷5¹² is simplified to 5^15
<h3>What are index forms?</h3>
Index forms are defined as the exponent or power of a number or variables.
It is also seen as a mathematical method of writing numbers that are too large or too small in simpler forms.
The laws of exponents are;
- Add the powers when they are being multiplied the bases are the same
- Subtract the exponents when they are divided and have the same base.
- Multiply the exponents when the bases are the same
Given the expression;
(5³)⁹÷5¹²
This is represented as;
(5³)⁹/5¹²
expand the bracket
5^27/5^12
Take the inverse exponent of the denominator
5^27-12
5^15
Thus, the simplified form is 5^15
