A family has two cars. The first car has a fuel efficiency of 40 miles per gallon of gas and the second has a fuel efficiency of

15 miles per gallon of gas. During
one particular week, the two cars went a combined total of 1625 miles, for a total gas consumption of 50 gallons. How many gallons were consumed by each of
the two cars that week?

Answer:

first car = 35, second car= 15

Step-by-step explanation:

40x+15y=1625

x+y=50

multiplying the 2nd by -15 and add the 2 equations, we get x= 35 and by substituting on second equation we get y= 15

Answer:

0.17

Step-by-step explanation:

2.9^2 ÷ 50 = 0.1682

rounded to nearest hundredth which is the 6 so your answer is

0.17

*remember to round you look at the place to the right if its 4,3,2,1, or 0 it stays the same if it 5,6,7,8 or 9 it goes up one and all the numbers behind it turns to zeros

I hope this helps!!

According to the Census Bureau, in 2014 California had an estimated population of 3.88 x 10^7 and Wyoming had an population of 5
Verdich [7]
The population of California is 3.88 x 10^7 - 5.84 x 10^5 = 3.82 x 10^7 more than the population of Wyoming. Alternatively the population of California is 3.88 x 10^7 / 5.84 x 10^5 = 66 times the population of Wyoming.

Find the sum of the geometric series for which a = 160, r = 0.5, and n = 6.
harina [27]

\\ \sf\longmapsto S_n=\dfrac{a(1-r^n)}{1-r}

\\ \sf\longmapsto S_n=\dfrac{160(1-0.5^6)}{1-0.5}

\\ \sf\longmapsto S_n=\dfrac{160(1-0.015625)}{0.5}

\\ \sf\longmapsto S_n=\dfrac{160(0.984378)}{0.5}

\\ \sf\longmapsto S_n=80(0.984378)

\\ \sf\longmapsto S_n=78.75

Suppose you have a complete, weighted graph with 8 vertices. How many Hamilton Circuits are there in this graph?
Natali5045456 [20]

The number of Hamilton Circuits with 8 vertices are 5040.

Given that, a complete, weighted graph with 8 vertices.

<h3>What are Hamilton Circuits?</h3>

A Hamiltonian circuit is a circuit that visits every vertex once with no repeats. Being a circuit, it must start and end at the same vertex. A Hamiltonian path also visits every vertex once with no repeats, but does not have to start and end at the same vertex.

For N vertices in a complete graph, there will be (n−1)!=(n−1)(n−2)(n−3)…3⋅2⋅1 routes. Half of these are duplicates in reverse order, so there are (n−1)!/2 unique circuits.

A complete graph with 8 vertices would have = 5040 possible Hamiltonian circuits. Half of the circuits are duplicates of other circuits but in reverse order, leaving 2520 unique routes.

Therefore, the number of Hamilton Circuits with 8 vertices are 5040.
