Step-by-step explanation:
Answer:
XY=4
CE=14
Step-by-step explanation:
A)since the 2 traingles are similar, there is a ratio between the 2 of them. we can find that by dividing the side :10/25 =0.4. so XYZ is 0.4 of PQR. to check that we can try to multiply pr by 0.4 to see if it gets XZ. 25 • 0.4 =10.To get XY we will do the same thing: PQ • 0.4 = 10 • 0.4 = 4
B)AB= 7
CD= AB =7
AD = 3 AB
AD = 3•7
AD= 21
Since ABCD is congruent to DEFG
AD =ED = 21
CE = ED-CD = 21-7=14
Answer:
(n+5)/6
n is a number plus 5. All divided by 6
Answer: The correct answer is x=5
Step-by-step explanation:
x=2−5−−75=2−5−5i3=−2.5000−4.3301i
x=2−5+−75=2−5+5i3=−2.5000+4.3301i
x=5

Answer:
9.14
Step-by-step explanation:
The family vehicle can go 300 miles on a tank of gas worth $40.
1. Find the cost of the gas in two options for Day 1.
First option:
300 miles - $40
304 miles - $x
Write a proportion:
\begin{lgathered}\dfrac{300}{304}=\dfrac{40}{x}\\ \\300x=304\cdot 40\\ \\30x=304\cdot 4\\ \\30x=1,216\\ \\x=\dfrac{1,216}{30}=\dfrac{608}{15}\approx 40.53\end{lgathered}
304
300
=
x
40
300x=304⋅40
30x=304⋅4
30x=1,216
x=
30
1,216
=
15
608
≈40.53
Second option:
300 miles - $40
260 miles - $y
Write a proportion:
\begin{lgathered}\dfrac{300}{260}=\dfrac{40}{y}\\ \\300y=260\cdot 40\\ \\3y=26\cdot 4\\ \\3y=104\\ \\=xy\dfrac{104}{3}\approx 34.67\end{lgathered}
260
300
=
y
40
300y=260⋅40
3y=26⋅4
3y=104
=xy
3
104
≈34.67
2. Calculate the total price:
First option:
Gas cost = $40.53
National park = $25
Lakes - free
Total cost = $65.53
Second option:
Gas cost = $34.67
Water park for 4 persons =4\cdot \$5=\$20=4⋅$5=$20
Amusement park for 4 persons =4\cdot \$5=\$20=4⋅$5=$20
Total cost =$74.67
Difference = 74.67 -74.67−65.53 = $9.14
