Answer: The answer is 3 3/5 because you divide 2 1/4 and 5/8 you do KCF keep change flip but since it is a whole number divided by a fraction you multiply the whole number with the denominator and than add it by the numerator so no the problem is 9/4 • 8/5 which is 72/20 which is a improper fraction so it is 3 12/20 but it can be reduced to 3 3/5 and thats how you do it.
Step-by-step explanation:
We need to find the height of the triangle first.
Height=>sin(60°)=h/3 but sin(60°)=√3/2
h=3×√3/2=3√3/2
Area=½×base×height
A=½×3×3√3/2
A=9√3/4
Answer is option A
Answer:
a
Step-by-step explanation:
just read through the answer choices and you can see that the other three are wrong
Answer:
Cost of Pizza for 1 inch radius is $0.5.
The Direct variation between cost of pizza and radius in inches of pizza is
Step-by-step explanation:
Given:
Cost of 6 inch pizza = $3.00
We need to find the direct variation equation to represent cost of pizza with a 1 inch radius.
Let Cost f Pizza be represented by 'C'.
Also radius in inches of pizza be represented by 'r'.
First we will find Cost of pizza for 1 inch radius.
Now 6 inch pizza = $3.00
So 1 inch Pizza = Cost of pizza for 1 inch radius.
By Using Unitary method we get;
Cost of pizza for 1 inch radius =
Cost of Pizza for 1 inch radius is $0.5.
Hence We can say the direct variation would be given as;
Hence The Direct variation between cost of pizza and radius in inches of pizza is
So the first one, 1.2 >11/5. and the second one 1/3> 1/2
