Answer:
D.
Step-by-step explanation:
We can see from our graph that triangle CED is similar to triangle CBA. Side length BA corresponds to ED and Side length AC corresponds to DC.
Since we know that corresponding sides of two similar triangle are in the same proportion. To find value of x we will set proportion of the corresponding sides of our given triangles equal.
Upon cross multiplying our given equation we will get,

Upon distributing 7 we will get,




Therefore, x equals 8.57 and option D is the correct choice.
Answer:
c
Step-by-step explanation:
Answer: 254.5
Step-by-step explanation:
Length x width is the formula.
so 18 x 18 for 7.
22 x 24 for 8.
and 8 would probably be 5 x 5 to equal 20. so the length and width would be 5 and 5 because 20 is the area
Answer:
(a) $7/ticket
(b) 3 cats/dog
(c) 10 ft/sec
(d) 16 cups/gal
Step-by-step explanation:
(a) $35 for 5 tickets
$35/(5 tickets) = $7/ticket
(b) 21 cats and 7 dogs
21 cats/(7 dogs) = 3 cats/dog
(c) 40 ft in 4 seconds
40 ft/(4 sec) = 10 ft/sec
(d) 48 cups for 3 gallons
48 cups/(3 gal) = 16 cups/gal
