Greta uses 6 ounces of pasta to make 6 /7 of a serving of pasta. How many ounces of pasta are there per serving?

Answer:

Step-by-step explanation:

Given that Henry  deposited $420 into a savings account. There is a $5.00 per month service fee on the account. Also, Henry decides he wants to withdraw $25 a week for spending money.

Let us convert everything into days.

30 days a month and 7 days in a week

Service charges for 30 days = 5

withdrawn amount for 7 days = 25

Let x be the total no of days

Then [tex]\frac{25x}{7} +\frac{5x}{30}= 420\\\\750x+35x=420(7)(30)\\785x=420(7)(30)\\x=112.3567[/tex]

i.e. between 3 and 4 months

We can say in 3 months this will be exhausted.

Option A

If the street is already 24 m wide, and it is being expanded by 125%, then the correct answer is C. 30 m!

125% simply means 1 1/4.     1/4 of 24 is 6.    So, you have 24 + 6 = 30!

Answer:

The correct answer is C: the new street should be 30m wide.

Step-by-step explanation:

This is a simple problem of per-cents. Perhaps the easiest way to do it is to use a basic ‘‘rule of three’’. In this particular case the 100% is the width of the old street, i.e. 24 m; and we want to know the new width, that is 125% of the old street. So,

                   24 ---- 100%

                    x  ----- 125%

To find x we use the formula

[tex]x = \frac{24*125}{100} = 3000/100=30[/tex]

So, the width of the new street is 30m.

First, turn the two fractions into decimals : 7/9 = .77777 7/8 = .875

Now, all of the numbers are in common form so you can identify which is largest, etc. : .875, .77777, .7

Now put the values back to fractions : 7/8, 7/9, .7

The formula for area of this shape is (a+b)/2 * h

a = 8

b= 12

h = 6

Area = (8+12)/2 * 6

Area = 20/2 * 6

Area = 10 * 6

Area = 60 sq. m.

Answer:

[tex]V_{E} = -22.5 / 15 = 1.5 miles/minute\\V_{F} = 7.5 / 15 = 0.5 miles/minute[/tex]

Step-by-step explanation:

To answer this problem, we must bear in mind that the express train travels 3 times faster than the freight train.

If we call F the distance that the freight train travels and we call E at the distance that the express train travels, we must have the distance between them after 15 minutes it must be 30 miles.

So

[tex]F + E = 30\\[/tex]

We also know that:

[tex]E = 3F[/tex]

Since the express train travels 3 times faster than the freight train.

So, like both equations, we have to:

[tex]F + 3F = 30\\F = 30/4\\F = 7.5 miles\\[/tex]

Then [tex]E = 7.5*3 = 22.5[/tex] miles in the opposite direction.

This is the distance you traveled in 15 minutes.

Therefore, the speed of the express train ([tex]V_{E}[/tex]) is the distance traveled between the time it did

[tex]V_{E} = -22.5 / 15 = 1.5 miles/minute\\V_{F} = 7.5 / 15 = 0.5 miles/minute[/tex]

When the 12 numbers are listed in order, they are ...

... 13, 15, 18, 20, 23, 23, 27, 29, 30, 32, 36, 38

The extreme values are 13 and 38. Only the third plot has the ends of the whiskers on these values.

Since there are an even number of numbers, the median is the average of the middle two: (23 +27)/2 = 25. Only the third plot shows the median at 25.

Since each half of the data set has an even number of numbers, the 1st and 3rd quartile values are the averages of the middle two numbers in each half:

The third plot has the ends of the box in these places, confirming it is the correct choice.

The appropriate choice is the third one.

To find the y value in this line, we can simply plug 2 into the variable x and solve.

2(2) + 5

4 + 5 = 9

The y value for x 2, is 9.

This can be displayed as (2, 9).

Using the slope intercept relation, the missing y value in the points given is 9.

Given the slope intercept equation :

Substituting the value of x into the equation and solving for y :

The linear equation for the total combination age is [tex]X+7+(X+4)+7=24[/tex]

Step-by-step explanation:

If Jane is X years old today. And her brother is 4 years older then her brothers age is,

X+4.

Jane's age after 7 years = X+7

Jane's Brothers age after 7 years = (X+4)+7

Step-by-step explanation:

Answer:

2.72 m/s

Step-by-step explanation:

We are given that

Boy jogs=250 meters

Time taken by boy=110 seconds

We have to find the average speed in m/s

In order to find the average speed then we will divide distance by time

[tex]Average\;Speed=\frac{distance}{time}[/tex]

Using the formula then we get

Average speed=[tex]\frac{250}{110}=2.72 m/s[/tex]

Hence, the average speed=2.72 m/s

Final answer:

To calculate the average speed, the boy's distance jogged (250 meters) is divided by the time taken (110 seconds), yielding an average speed of 2.27 m/s.

Explanation:

The student's question asks how to calculate the average speed of a boy who jogs a certain distance in a given amount of time. To find the average speed, you divide the total distance traveled by the total time taken. In this case, the boy jogs 250 meters in 110 seconds.

The calculation for the average speed (v) would be:

Distance (d) = 250 meters

Time (t) = 110 seconds

Average Speed (v) = d / t

Plugging the values into the equation yields:

Average Speed (v) = 250 m / 110 s = 2.27 m/s

Hence, the boy's average speed is 2.27 meters per second.

"The correct answer is that diagrams showing how matter moves through organisms and the environment are called cycles because they depict continuous, circular pathways.

In ecosystems, matter is not created or destroyed but is continuously recycled. This recycling process occurs in a loop or cycle, where matter moves from the environment to organisms and then back to the environment. For example, in the carbon cycle, carbon dioxide is taken in by plants during photosynthesis, then passed on to animals that consume the plants, and eventually returned to the environment through processes like respiration and decomposition.

These cycles are essential for the sustainability of ecosystems because they ensure that nutrients and other materials are reused and not depleted. The term ""cycle"" reflects the repeating and ongoing nature of these processes, highlighting the interconnectedness and interdependence of organisms and their environment. By using diagrams to represent these cycles, we can visualize and better understand the complex interactions and pathways that matter follows in ecosystems."

Standard form of non-polynomials is purely to solve them.

10^4 = 10,000

2.1 * 10,000 = 21,000

Let's have the first number be x, the second number y, and the third number z.

Because the second number is six more than the first, y = x + 6.

Because the third number is twice the first, z = 2x.

The three numbers added together equals 26, so 26 = x + y + z.

Let's substitute y = x + 6 and z = 2x into 26 = x + y + z.  This gives us:

26 = x + x + 6 + 2x

26 = 4x + 6

We subtract 6 from both sides of the equation and divide by 4 to get:

5 = x

Now, we'll put x = 5 into our previous to equations to find y and z:

y = 5 + 6

y = 11

z = 2*5

z = 10

Let's check out answer.  10 + 11 + 5 = 26.  10 is twice of 5 and 11 is 6 more than 5.  Thus our three numbers are 10, 11, and 5.

The three numbers are 5, 11 (5 + 6), and 10 (2 * 5)

Let's call the first number x

The second number is 6 more than the first, so it is x + 6

The third number is twice the first, so it is 2x

The sum of the three numbers is 26, so we have the equation x + (x + 6) + 2x = 26

Combining like terms, we get 4x + 6 = 26

Subtracting 6 from both sides, we get 4x = 20

Dividing both sides by 4, we get x = 5

So the three numbers are 5, 11 (5 + 6), and 10 (2 * 5)
