Answer:
The ratios are not equal.
Step-by-step explanation:
To justify the answer we will assume the dimes and quarters.
Let number of dimes be denoted by 'x'.
Let number of quarters denoted by 'y'.
In Siri's coin purse
Number of dimes (x) = 6
Number of quarters (y) = 4
Therefore ratio of quarter to dimes we get;
⇒ equation 1.
In Martha Coin purse.
Number of dimes (x) = 5
Number of quarters (y) = 3
Therefore ratio of quarter to dimes we get;
⇒ equation 2.
Now we will check if both have the same ratios.
We will check by making both equation 1 and equation 2 equal.
By cross multiplication we get;
Hence the ratios are not equal.
Answer:
3 by 2
Step-by-step explanation:
3+2+3+2=10
3*2=6
Hope this Helps!!!
The perimeter is the sum of the lengths of the sides.
1) Upper base: 6 - 4 = 2 units
2) Lower base: 8 - 2 = 6 units
3) left side:
left side ^2 = (4 - 2)^2 + (9 - 4)^2 = 2^2 + 5^2 = 4 + 25 = 29
=> left side = √29 units
4) rigth side = (8 - 6)^2 + (9 - 4)^2 = 29
=> right side = √29 units
5) Perimeter = 2 units + 6 units + √29 units + √29 units = 8 + 2√29 units
Answer: option D. 8 + 2√29 units
Answer: The answer is D :)
