$238.60
divide 1,550.90 by 6.5 = 238.60
check
238.60 x 6 = 1,431.60
238.60 / 2 = 119.30
total 1,550.90
Answer: <em>One ticket cost about $800 or to be exact: $824</em>
<em />
Step-by-step explanation:
You know that there are 3 plane tickets and total is is $2472.
To find out for ONE ticket, you can divide 2472 by 3 as shown below:
2472 ÷ 3 = 824
E=number of eight cent stamps
t=number of ten cent stamps bought
w=number of 2 cent stamps bought
number of eight=number of ten
e=t
as many 2 cent as the other 2 combined
e+t=w or
2e=w=2t
total she bouthgt 4.40
4.40=440 cents
8e+10t+2w=440
solve for t or e, I solve for t
8t+10t+2(2t)=440
18t+4t=440
22t=440
divide 22
t=20
t=e
20=e
w=2e
w=2(20)
w=40
answer is
20 eight cent
20 ten cent
40 two cent
Answer:
2.5 ft
Step-by-step explanation:
The figure for the given scenario is shown below.
There are two right angled triangles, ΔACD and ΔBCD
The height of flag staff is represented by segment AB, BC is the height of pedestal stand , D is a point on the ground that makes angles 30° and 60° with the bottom and top of staff at B and A respectively.
AB = 5 ft. Let the height of pedestal stand be 
ft and the distance of point D from the bottom of stand be 
ft as shown in the figure.
Now, from ΔACD,
From ΔBCD,
Plug in the value of in the first equation and solve for .
.
Therefore, the height of the pedestal stand is 2.5 ft.
