Answer:
23.00
Step-by-step explanation:
If you want to leave a 20% tip, multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total including tip. If you want to leave a 18% tip, multiply the cost by 0.18 to get the tip amount or multiply the cost by 1.18 to get the total including tip.
To answer the question, let x be the number of adults going to the zoo and 2x be the number of children. The total amount gained from the ticket sales should be,
1650 = 6x + 4(2x)
The values of x is equal to 117.86. Therefore, the school bought approximately 118 tickets for adults and 236 for children.
Answer:
the P value is 45.22%
Step-by-step explanation:
The computation of the P value is as follows;
Given that
standard deviation = 14.9
mean = 675
Reduction in diameter= 673.2
Based on the above information,
We have to applied the following formula i.e.

Now the P value for -0.1208 is 0.4522 i.e. 45.22%
Hence, the P value is 45.22%
The same is to be considered
Change the information into an equation and do sequence. pull out any necessary information.
y = 2x + 1
starts at 1... so your first sequence is 1.
plug in x=1 then it becomes 3. then the next sequence you plug in 3 (, the answer to your previous solve) you get 7. continue to do this. next sequence you plug in x=7 into the equation y = 2x + 1.
thus, y = 2(7) + 1 =15... so forth...
therefore the answer is B.
Hope this helps :)
Answer:
8 Faces
Step-by-step explanation:
The Euler’s formula is:
V-E+F=2
Where V is number of vertices, E is number of edges and F is number of faces.
In our example, E=20, V=30, so we have:
30-20+F=2
10-F=2
F=8
