4.5÷6=estimate the quotient
2 answers:
<u>We are given the expression:</u>
4.5 / 6
<u>Simplifying the given expression:</u>
<em>We can rewrite 4.5 as 4/10:</em>
<em /><em />
<em>Since 45 and 6 have a common factor: 3</em>
<em /><em />
<em>The 3 in the numerator and the denominator will cancel out:</em>
<em /><em />
<em>We know that 15/2 is 7.5</em>
0.75
Hence, the quotient of the expression: 4.5/6 is 0.75

Answer: Third option 15.75 m
Answer:
Step-by-step explanation:
The given trapezoid has vertices at A(−1,4), B(0,2), C(1,2) and D(2,4).
The transformation rule for 90° counterclockwise rotation is
This implies that:
This is followed by a translation 3 units to the right.
This also has the rule:
Therefore:
As you've got 15%, the best thing to do is to find 10%, then multiply it by 1.5. Once you've found the tip, you add this onto the cost of the meal.
Therefore, the total cost of $25 meal with a 15% tip is $28.75
Hope this helps :)
