how many times does 18 go into 40

To find out what percent of the distance Ava has walked so far, we can set up a proportion and solve for x. Ava has walked 60% of the distance to the train station.

To find out what percent of the distance Ava has walked so far, we can set up the following proportion:

15/25 = x/100

Where 15 is the distance Ava has walked, 25 is the total distance to the train station, x is the unknown percentage, and 100 represents 100%. To solve for x, we can cross multiply and divide:

15 * 100 = 25 * x

1500 = 25 * x

Dividing both sides by 25, we get:

x = 1500/25

x = 60

Therefore, Ava has walked 60% of the distance to the train station.

Final answer:

To find the percent of the distance Ava has walked so far to the train station, divide the distance she has walked by the total distance and multiply by 100. In this case, Ava has walked 15 blocks out of 25 blocks, so she has walked 60% of the distance.

Explanation:

To find the percent of the distance Ava has walked so far, you can divide the distance she has walked by the total distance to the train station and then multiply by 100.

In this case, Ava has walked 15 blocks out of 25 blocks to the train station. So, the percent of the distance she has walked so far can be calculated as:

Percentage = (15/25) * 100 = 60%

Step-by-step explanation:

we know that

In a circle, a radius that bisects a chord is perpendicular to the chord

so

CS is perpendicular to AC

The triangle GFC is a right triangle

Remember that the sum of the measures of the interior angles in a triangle must be equal to 180 degrees

m∠CGF+m∠GFC+m∠GCF=180°

we have

Length of sides of quadrilateral are 8 feet, 8 feet, 16 feet, 24 feet

Given that length of the sides of a quadrilateral are in extended ratio 1:1:2:3

Perimeter of the quadrilateral = 56 feet

Need to determine length of the sides

As length of the sides of a quadrilateral are in extended ration 1: 1: 2: 3  

lets assume that four sides of rectangle = 1x, 1x, 2x and 3x

Perimeter of quadrilateral = sum of length of four sides  

=> Perimeter of quadrilateral = 1x + 1x + 2x + 3x = 7x

As given that perimeter = 56 feet

=> 56 = 7x

x = 8

Then the length of sides are:

1x = 1(8) = 8 feet

1x = 1(8) = 8 feet

2x = 2(8) = 16 feet

3x = 3(8) = 24 feet

Answer:

66 pints of 70% pure fruit juice and 44 pints of 95% pure fruit juice must be used.

Step-by-step explanation:

Let

x ----> pints of pure fruit juice at 70%

y ----> pints of pure fruit juice at 95%

we know that

[tex]x+y=110[/tex] ----> [tex]x=110-y[/tex] ----> equation A

Remember that

[tex]70\%=70/100=0.70[/tex]

[tex]95\%=95/100=0.95[/tex]

[tex]80\%=80/100=0.80[/tex]

so

[tex]0.70x+0.95y=0.80(110)[/tex] ----> equation B

Solve the system by substitution

substitute equation A in equation B

[tex]0.70(110-y)+0.95y=0.80(110)[/tex]

solve for y

[tex]77-0.70y+0.95y=88[/tex]

[tex]0.25y=88-77[/tex]

[tex]0.25y=11[/tex]

[tex]y=44[/tex]

Find the value of x

[tex]x=110-y[/tex] ---> [tex]x=110-44=66[/tex]

therefore

66 pints of 70% pure fruit juice and 44 pints of 95% pure fruit juice must be used.

Answer:

The speed of River's mom drove for 10 miles distance is 0.234 mph

The speed of  River's mom drove for 25 miles is 10.234 mph  

Step-by-step explanation:

Given as :

The first distance cover by River's mom = 10 miles

The rate of speed = x mph

The second distance cover by river's mom = 25 miles

The rate of speed = x + 10 mph

The total driving time = 45 min

Now, According to question

Time = [tex]\dfrac{\textrm Distance}{\textrm speed}[/tex]

So, 45 = [tex]\dfrac{10}{x}[/tex] +  [tex]\dfrac{25}{x + 10}[/tex]

Or, 9 = [tex]\dfrac{2}{x}[/tex] +  [tex]\dfrac{5}{x + 10}[/tex]

Or, 9 × x × ( x + 10 ) = 2 × ( x + 10 ) + 5 x

Or, 9 x² + 90 x = 2 x + 20 + 5 x

Or, 9 x² + 90 x = 7 x + 20

Or, 9 x² + 90 x - 7 x - 20 = 0

Or, 9 x² + 83 x - 20 = 0

Solving this quadratic equation

x = [tex]\frac{-b\pm \sqrt{b^{2}-4\times a\times c}}{2\times a}[/tex]

Or, x = [tex]\frac{-83\pm \sqrt{83^{2}-4\times 9\times (-20)}}{2\times 9}[/tex]

Or, x = [tex]\frac{-83\pm \sqrt{7609}}{18}[/tex]

∴  x = [tex]\frac{-83+87.22}{18}[/tex] , tex]\frac{-83-87.22}{18}[/tex]

I.e x = 0.234 , - 9.4567

We consider x = 0.234

So, The speed for 10 miles distance = x = 0.234 mph

and The speed of 25 miles = x + 10 = 0.234 + 10 = 10.234 mph

Hence The speed of River's mom drove for 10 miles distance is 0.234 mph

and The speed of  River's mom drove for 25 miles is 10.234 mph   Answer

Final answer:

To find the two driving speeds, use the distance formula and set up two equations. Simplify the equations to find the speeds.

Explanation:

To find the two driving speeds at which River's mom drove, we can use the formula distance = speed x time. We know that the total driving time was 45 minutes. We can set up two equations using the given information:

10 = x ⋅ (45/60)

25 = (x + 10) ⋅ (45/60)

Simplifying the equations, we get:

x = 20 mph

x + 10 = 30 mph

Therefore, River's mom drove at speeds of 20 mph and 30 mph.

One kilogram is made of 1000 grams. So, 1/2kg is made of 500 grams. If we add 250 grams, we have 750 grams, or 0.75kg.

To increase 1/2 kg by 250g, add the two values is 750g.

In mathematics, we often encounter situations where we need to perform operations with different units of measurement. In this case, you want to increase 1/2 kg by 250g. The first step is to convert both quantities to a common unit to facilitate the addition.

Step 1: Convert 1/2 kg to grams

We know that 1 kg is equal to 1000 grams (1 kg = 1000g). To find out how many grams are in 1/2 kg, we multiply 1/2 by 1000:

1/2 kg * 1000g/kg = 500g.

So, 1/2 kg is equivalent to 500g.

Step 2: Perform the addition

Now, we have both quantities in the same unit (grams). The addition becomes straightforward:

500g + 250g = 750g.

Thus, when you increase 1/2 kg by 250g, the result is 750 grams.

In summary, to add quantities with different units, it's crucial to convert them into the same unit before performing the operation. Here, we converted kilograms to grams and then added the values to get the final result of 750g.

She ran 6.71km in the evening

Step-by-step explanation:

3km 290m = 3.29km

10 - 3.29 = 6.71km

Sylvia ran 6 km 710 m in the evening.

Given that, Sylvia ran a total of 10 km and 3 km 290 m in the morning.

We need to find the number of kilometres she ran in the evening.

When we are dealing with two numbers that are expressed in units, if the units are the same, we can add or subtract normally. However, if the units are different, then we can add or subtract only if the units can be converted into the same units.

Now, 3 km 290 m can be written as 3.29 km

So the distance ran in the evening =10-3.29

=6.71 km

=6 km 710 m

Therefore, Sylvia ran 6 km 710 m in the evening.

Answer:

byzantine style of architecture is an example of haggis sophias style

Step-by-step explanation:

Final answer:

To find out how much stock is needed for 4 servings of Mrs. Young's haggis recipe, we use proportional relationship calculations to arrive at 3/4 cup of stock.

Explanation:

The student needs to determine how much stock Mrs. Young will need for 4 servings of her haggis recipe if the original recipe, which serves 12, calls for 2 1/4 cups of stock. To solve this, a proportional relationship can be used, as follows:

Multiply the number of servings in the original recipe by the amount of stock to find the stock per serving.

Divide the original number of servings (12) from the result to find the stock needed for one serving.

Multiply the amount of stock for one serving by the new number of servings (4) to determine the total stock needed.

The calculation would be: (2 1/4 cups ÷ 12 servings) × 4 servings. Since 2 1/4 cups is equal to 9/4 cups, the arithmetic gives us: (9/4 cups ÷ 12) × 4 = 3/4 cup of stock needed for 4 servings.

The slope of a line graphed to represent the volume of water in a pool over time will be 6 and the equation of the line representing the table

y = - 6x + 50

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

We have a table as given in the question as follows -

Time (in minutes)         Water (in gallons)

0                                         50

1                                          44

2                                         38

3                                         32

4                                         26

5                                         20

We can write the slope of the line as follows -

The slope of the line will be -

m = (y₂ - y₁)/(x₂ - x₁)

m = (44 - 50)/(1 - 0)

m = -6

At [x] = 0, the [y] coordinate is 50. Therefore, the equation of the line representing the table -

y = - 6x + 50

Refer to the graph attached.

Therefore, the slope of a line graphed to represent the volume of water in a pool over time will be 6 and the equation of the line representing the table y = - 6x + 50

A baker's dozen (13) of cookies is on sale  for $2.08. What is the cost of an individual  cookie?

Answer:

The cost of an individual cookie is $0.16

Step-by-step explanation:

Given

Specifically, it was stated that the baker's dozen is 13 pieces

Hence. A dozen cookies = 13 cookies

Price of a dozen cookies = $2.08

In other words, the price of 13 cookies is $2.08

To get the cost of an individual cookie, we have to divide the price of a dozen cookies by the number of cookies. This is calculated as follows:

[tex]Cost of Cookies = \frac{Price of Cookies}{Number of Cookies}[/tex]

By Substituting the right values,

[tex]Cost of Cookies = \frac{Price of Cookies}{Number of Cookies}[/tex]  

becomes

[tex]Cost of Cookies = \frac{2.08}{13}[/tex]

[tex]Cost of Cookies = 0.16[/tex]

Hence, the cost of an individual cookie is $0.16
