Answer:
1. 3/8
Step-by-step explanation:
Total tossed times = 3
Total Possibilities = 8
Possibilities = (Head, Head, Head), (Tails,Tail,Tails), (Head,Head,Tails), (Head,Tail,Head), (Tails,Head,Head), (Head,Tail,Tail), (Tail,Tail,Head), (Tail,Head,Tail)
Number of options with a head and two tails = 3
So, Probability = Number of correct options ÷ Number of total possibilities
= 3 ÷ 8 or 3/8
Answer:
Kayla and Maddy will be in the same level in 4 days.
Step-by-step explanation:
Kayla: y = 6x + 12
Maddy: y = 2x + 28
6x + 12 = 2x + 28
Subtract 2x from both sides;
4x + 12 = 28
Subtract 12 from both sides;
4x = 16
Divide both sides by 4;
x = 4
The ratio of corresponding sides is same for all the sides for similar polygon. the correct proportion is,

Thus the option H is the correct option.
To find the correct proportion we need to know about the properties of slimier polygon.
<h3>What are the properties of similar polygon?</h3>
Two polygons are said to be similar or congruent pentagon-
The corresponding angle of two pentagons are congruent.
The ratio of corresponding sides is same for all the sides.
The figure given in the problem of similar two polygons with six sides.
Rearrange the second figure as shown in figure.
As for the similar polygons, the ratio of corresponding sides is same for all the sides.
Thus the sides shown in the two rearranged figure must be same. Therefore,

Hence the correct proportion is,

Thus the option H is the correct option.

Answer:
First one
Step-by-step explanation:
First choose because they are all multiply by 5
N and d are both numbers of thousands of dollars.
Thus, if n = 1, that means $1000.
Here n = d + 0.4.
Note that in C, n+0.04=n is completely wrong.
Similarly, in D, d = 0.04 = n is completely wrong.
The "combined profit amount" for Nov. and Dec. is n + d = 3.15.
Only A matches this info. Your answer is A.
