Answer:

Blue bottle holds more.

Step-by-step explanation:

Given:

Green Bottle = 8 3/5 = 43/5

Blue Bottle = 8 6/7 = 62/7

Now:

we can write 43/45 as;

43/5 x 7/7 = 301/35     (1)

similarly, 62/7 = 62/7 x 5/5 = 310/35   (2)

Comparing both (1) and (2),

301/35 < 310/35

:. (301 < 310)

Hence,

Blue Bottle will hold more.

The equation for the given situation is 5+10.50x=68.

Given that, the parking garage charges an initial fee of 5$.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the number of hours be x.

Garage charge $10.50 per hour parked. You had to pay $68.

So, equation is 5+10.50x=68

Therefore, the equation for the given situation is 5+10.50x=68.

Step-by-step explanation:

Each one goes up by .75 cents

The obtained coordinate points to plot the graph are matching with graph C. Therefore, option C is the correct answer.

Given that, a car's odometer starts at 25 miles and for every 25 miles traveled, 1 gallon of gas is used.

In mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related".

Let the number of miles traveled be y, and the gallons of gasoline used be x.

Now, the equation for the given situation is y=25x

By substituting x = 1, 2, 3, 4, 5,....we get

y = 25(1) =25

y = 25(2) =50

y = 25 (3) =75

y = 25 (4) =100

So, the coordinates to plot the graph are (1, 25), (2, 50), (3, 75) and (4, 100) and so on.

The obtained coordinate points to plot the graph are matching with graph C. Therefore, option C is the correct answer.

Answer:

24 runners

Step-by-step explanation:

If 1/4 of the runners dropped out, then 1 - 1/4 or 3/4 continued on. 3/4 of 56 or 3/4 *56 is 42 runners left. Then, out of these 42, 3/7 dropped out. This means 1 - 3/7 or 4/7 of the runners remained. This means that 4/7 * 42 or 24 runners finished the race.

The prime factorization of 54 = 2 × 3 × 3 × 3 = 2 × 3.

Step-by-step explanation:

Factor 54 into two numbers, then factor each of those factors as much as possible until you can't factor a number.

54

=  = ( 9 ) ⋅ ( 6 )  

= ( 3 ⋅ 3 ) ⋅ ( 2 ⋅ 3 )

Answer: 50 feet

Step-by-step explanation:

Since it is a rectangle and you in the corner diagonally; you can draw a line diagonally across in the rectangle and you are left with two triangles.

So since its two right-angled triangles

a = 14 feet

b = 48 feet

You need to find c which is the diagonal.

Using the pythagorean theorem which is:

[tex]c^{2} = a^{2} + b^{2}[/tex]

[tex]c^{2} = 14^{2} + 48^{2}[/tex]

Square the a and b then add

[tex]c^{2} = 136 + 2304[/tex]

[tex]c^{2} = 2500[/tex]

Now carry over the square on the c and change it to the square root

[tex]c = \sqrt{2500}[/tex]

when you square root

[tex]c = 50[/tex]

therefore it is 50 feet diagonally across

Step-by-step explanation:

first pool :

in 4 hours the pool gets 5200 gallons.

that means in 1 hour it gets 5200/4 = 1300 gallons.

so, the filing rate is 1300 gallons / hour.

second pool :

we seen on the graph that

in 3 hours the pool gets 10800 gallons.

that means in 1 hour it gets 10800/3 = 3600 gallons.

so, the filing rate is 3600 gallons / hour.

therefore, the second pool fills at a much faster rate than the first pool (3600 gallons vs. 1300 gallons / hour).

Answer:

3/4 would be .75

Step-by-step explanation:

1/4 would be .25 because .25x4=1. Because the denominator is a 4 you are trying to find a number that when multiplied 4 times would equal 1 or 4/4.

Answer:

3/4 cannot be .34 because that is not what it is equal to when converted to hundredths.

Step-by-step explanation:

The decimal 0.34 is in the value hundredths. 3/4's value when converted to hundredths is 75/100 or 0.75. We get this by multiplying 3 and 4 by the same factor that brings 4 to 100, which is 25.

So, 4*25=100(denominator), and 3*25=75(numerator). The decimal value is 0.75. Therefore, 3/4 cannot be 0.34 because the values are not the same.
