If departure time of a train is 03 45 and arrival time is 04 50. What will be the journey time? * A)1 h 20 min B)1 h 10 min C)1 h 05 min

Answer:

4 dollars per pair of socks.

Step-by-step explanation:

You already determined that x and y have a proportional relationship, as y is four times the x value. Therefore, when x is 1, that means one pair of socks will be four dollars.

Another way to solve this is by forming a linear equation.

y = 4x

Any number plugged into x to represent pairs of socks will give the cost, y.

For example: y = 4(7), which simplifies to y = 28.

This means that for every one pair of socks, it costs four dollars.

Answer:

yes and $4

Step-by-step explanation:

7*4=28

11*4=44

13*4=52

15*4=60

Answer:

See Below.

Step-by-step explanation:

The sum of an A.P. is given by:

[tex]\displaystyle S_n=\frac{n}{2}(a+x_n)[/tex]

Where n is the number of terms, a is the initial term, and xₙ is the last term.

Therefore:

[tex]\displaystyle S_{30}=\frac{30}{2}\Big(a+x_{30}\Big)=15(a+x_{30})[/tex]

And likewise:

[tex]\displaystyle S_{20}=\frac{20}{2}\Big(a+x_{20}\Big)=10(a+x_{20})\\\\ S_{10}=\frac{10}{2}\Big(a+x_{10}\Big)=5(a+x_{10})[/tex]

Substitute:

[tex]15(a + x_{30}) = 3(10 (a + x_{20}) - 5(a + x_{10} ))[/tex]

Distribute:

[tex]15a+15x_{30}=30a+30x_{20}-15a-15x_{10}[/tex]

Simplify:

[tex]15x_{30}=30x_{20}-15x_{10}[/tex]

Simplify:

[tex]x_{30}=2x_{20}-x_{10}[/tex]

The nth term for an A.P. is:

[tex]x_n=a+d(n-1)[/tex]

Where a is the initial term and d is the common difference.

So, it follows that:

[tex]x_{30}=a+d(30-1)=29d+a\\ x_{20}=a+d(20-1)=19d+a\\ x_{10}=a+d(10-1)=9d+a[/tex]

Therefore:

[tex]29d+a=2(19d+a)-9d-a[/tex]

Which follows that:

[tex]29d+a=38d+2a-9d-a\\ \\ 29d=29d \\\\ d\stackrel{\checkmark}{=}d[/tex]

Answer: D. (2,0) and (2,5) have the same x-value by different y-values

In other words, the input x = 2 leads to multiple outputs y = 0 and y = 5 at the same time. A function is where any input leads to exactly one output only (assuming that input is in the domain). So whenever x repeats itself like this is when we don't have a function.

This polynomial is a quartic (4th degree polynomial), and it is not linear, cubic, or quadratic.

Answer:

v= 13

w= -32

Step-by-step explanation:

2v+6w=-36

5v+2w=1

2w= 1-5v

2v+ (3)(1-5v)= -36

2v+3-15v= -36

3-13v =-36

3--36= 13v

39= 13v

13 = V

5×13+2w=1

65+2w=1

1-65= 2w

-64=2w

I took the quiz

Answer:

3 11/16 pounds

Step-by-step explanation:

Lynne bought a bag of grapefruit, 1 5/8 pounds of apples, and 2 3/16 pounds of bananas. The total weight of her purchases was 7 1/2 pounds. How much did the bag of grapefruit weigh?'

The Total weight = Weight of grape fruits + Weight of Apples + Weight of Bananas

Let the weight of the grape fruit = x

7 1/2 = x + 1 5/8 + 2 3/16

x = 7 1/2 - (1 5/8 + 2 3/16)

Lowest Common Denominator = 16

x= 7 1/2 - 3 + ( 10+ 3/16)

x = 7 1/2 - 3 + (13/16)

x = 7 1/2 - 3 13/16

Lowest Common Denominator = 16

x= 4 (8 - 13/16)

x = 4 (-5/16)

x = 3 11/16 pounds

Therefore, the bag of grapefruits weighed 3 11/16 pounds

sodas = 135 hot dogs = 45

Step-by-step explanation:

(S stands for sodas and H stands for hot dogs)

S + H = 180

3H+H = 180

4H = 180

H = 45

S = 45*3

S = 135

Answer:

A __function__ is a relation that assigns exactly one output value to one input value.

Step-by-step explanation:

Answer:

A function is a relation that assigns exactly one output value to one input value.        

Answer:

The value of "X" would be 2.

To solve for x, you'd have to get it by itself. To do so, you'd simplify both sides by solv8ng the exonents of each side (2^2 = 4) and (2^3 = 8). This leaves you with 4x = 8, which you'd then divide both sides by 4. Thus getting 2 as a final answer.

Answer: Jane needs 1 11/ 12 cups of flour more to make the cookie dough

Step-by-step explanation:

Recipe for cookie dough= 3 2/3cups of flour

Amount of flour available for Jane = 1 3/4 cups of flour

Amount of flour Jane needs to add to make cookie dough

=3 2/3 - 1 3/4

changing to improper fraction to make it easier to subtract

11/3 -7/4 = (44- 21)/12 = 23/12  =  1  11/12  cups of flour

Answer:

The plant grew [tex]12\frac{1}{14}[/tex] inches

Step-by-step explanation:

Operations with Fractions

Felipe planted seeds for a science project. One of the plants grew 6 2/7 inches in the first week and 5 11/14 inches in the second week.

We are required to find the total growth during the two weeks. We have to find the sum of:

[tex]6\frac{2}{7}+5\frac{11}{14}[/tex]

Let's convert both fractions to improper form:

[tex]6\frac{2}{7}+5\frac{11}{14}=6+\frac{2}{7}+5+\frac{11}{14}[/tex]

Adding the integers:

[tex]6\frac{2}{7}+5\frac{11}{14}=11+\frac{2}{7}+\frac{11}{14}[/tex]

Now we find the LCM of 7 and 14 is 14, thus:

[tex]6\frac{2}{7}+5\frac{11}{14}=11+\frac{4}{14}+\frac{11}{14}[/tex]

[tex]6\frac{2}{7}+5\frac{11}{14}=11+\frac{15}{14}=11+\frac{14+1}{14}[/tex]

[tex]6\frac{2}{7}+5\frac{11}{14}=11+1+\frac{1}{14}[/tex]

[tex]6\frac{2}{7}+5\frac{11}{14}=12+\frac{1}{14}[/tex]
