Answer:

2.57 yards longer

Step-by-step explanation:

Step one:

given data

We are told that the Jiaozhou Bay Bridge in China, spans 26.4 miles

Also, The longest sea bridge in the United States is the Lake Pontchartrain Causeway in Louisiana, which spans 41,940 yards

Required

Unit conversion from yards to miles

Step two:

let us convert 41,940 yards to miles

We know that 1 yard is 0.000568182 miles

hence 41,940 yards is x miles

cross multiply we have

x= 41,940*0.000568182

x=23.83 yards

Hence the difference in their lengths is

=26.4-23.83

=2.57 yards

Answer:

40 and 35

Step-by-step explanation:

If we say the first car uses x gallons then the second car must use 75 - x gallons.

The distance travelled is the number of gallons used * the efficiency of the car.

20x + 15(75-x)=1325

20x + 1125 - 15x = 1325

5x = 200

x = 40

This means that the first car uses 40 gallons and the second car uses 75-40= 35 gallons

Answer:

4 your welcome have a nice day

If Bananas cost $0.56 per pound at Walmart. If I purchased bananas for $1.96 then 3.5 pounds of bananas purchased.

Let x represent the number of pounds of bananas you purchased.

The cost of bananas per pound is $0.56.

Therefore, the total cost of the bananas you bought is given by:

Total cost = Cost per pound × Number of pounds

$1.96 = $0.56 × x

To solve for x, we divide both sides of the equation by $0.56:

x = $1.96 / $0.56

Using a calculator, we can calculate the value of x:

x = 3.5

Therefore, you purchased approximately 3.5 pounds of bananas.

Answer:

17 horses and 19 geese

Step-by-step explanation:

Let x be the number of horses and y be the number of geese

We know that, horses have four feet and geese have 2 feet

It is given that

x+y=36 (i)

and

4x+2y=106 (ii)

Solve the two equations simultaneously by substitution,

From equation (i)

y=36-x (iii)

Substitute y with 36-x in equation (ii)

4x+2(36-x)=106

4x+72-2x=106

4x-2x=106-72

2x=34

x=17

Then

Substitute x=17 to equation (iii)

y=36-17=19

x=17, y=19

We therefore have 17 horses and 19 geese

Step-by-step explanation:

2.97/11= 0.27

4.74/18=0.26333

Answer: You should probably go for the $4.74

Step-by-step explanation:

Because you can pay that price and get 18 slices, but on the other hand,  if you get the other you would be paying 2.97 for only ONE package of sliced cheese. So you would pay for the $4.74 package of cheese to get more for your money.

Step-by-step explanation:

Given

[tex]x + y= 5[/tex] --- (1)

[tex]7x + 9y = 6[/tex] ---- (2)

Required

Find x and y

Make x the subject in (1)

[tex]x + y= 5[/tex]

[tex]x = 5 - y[/tex]

Substitute 5- y for x in (2)

[tex]7x + 9y = 6[/tex]

[tex]2y = -29[/tex]

Divide both sides by 2

[tex]y = -\frac{29}{2}[/tex]

Substitute this for y in [tex]x = 5 - y[/tex]

Step-by-step explanation:

Answer:

( 40 37 , − 39 37 )

Step-by-step explanation:

Answer:

2880 ways

Step-by-step explanation:

There can be only one arrangement in which boys and girls can sit.

G-B-G-B-G-B-G-B-G

but position of individual boy and girls can be changed.

So, there are 5 girls and 5 slots for them that means they can be arranged in 5! ways,

similarly boys have 4 slots, so they can be arranged in 4! ways.

now, one more thing to consider is that out of 5! arrangements of girls, with each arrangement boys can be arranged in 4! different positions.

so to get the total number of boys and girls arrangements together we would need to multiply the arrangements of both boys and girls.

so the desired answer would be: 5!*4! = 120*24 = 2880 ways.

There are 2880 ways for 5 boys and 4 girls to be seated on a bench so that the girls and the boys occupy alternate seats.

The number of possible arrangements for a given set is calculated mathematically, and this process is known as permutation. Simply said, a permutation is a term that refers to a variety of possible arrangements or orders. The arrangement's order is important when using permutations. A permutation is a way to arrange each component in the proper order. The combination is a choice of components from a group.

Given There are 5 girls and 4 boys needed to be seated on the bench so that boys and girls occupy alternate seats.

There can only be one seating arrangement for boys and girls.

G-B-G-B-G-B-G-B-G

However, the location of each boy and girl can be adjusted individually.

Girls can be ordered in 5 ways since there are 5 slots available for them, and boys can be placed in 4 ways because there are 4 slots available for them. There is also the fact that boys can be put in 4! distinct positions for each of the 5! configurations of girls.

Therefore, we would need to multiply both the boys' and girls' arrangements in order to determine the total number of boys' and girls' arrangements.

Therefore, 5!*4! = 120*24  or 2880 ways would be the desired response.
