Answer:

[tex]D_x\approx14.8mile[/tex]

Step-by-step explanation:

From the question we are told that

Distance between Edenville and Westfalls [tex]D_1=7[/tex]

Distance between  Westfalls  and Concord [tex]D_2=13[/tex]

Generally the equation for Pythagoras is mathematically given by

[tex]D_x^2=D_1^2+D_2^2[/tex]

[tex]D_x^2=7^2+13^2[/tex]

[tex]D_x=\sqrt{ 7^2+13^2}[/tex]

[tex]D_x=14.76482306mile[/tex]

The distance b/w Edenville to Concord is

[tex]D_x\approx14.8mile[/tex]

Answer: In general, look for key words like "is" and "are,"  or "be." These become the equal sign in the equation.

Other key words to help decide which operation to use:

"And," "plus," and "the total of. . ." are clues for addition.

"Difference" or anything that means distance or amount between two given values is a signal for subtraction.

When Linear dimensions are given and Area is to be found, it will be a multiplication equation. The words "times" and "by" usually mean multiply.

Fractions are often multiplied by some other number.

Ratios are usually division problems.

When a total amount is distributed among some number of people, or you need to find out how many people will get a given share or portion, it is a division equation.

Step-by-step explanation:

It's much easier to explain with specific examples. Here is one.

We set up 15 rows of  6 seats in each row. How many seats are there altogether?

Of is the clue for multiplication Are becomes the equal sign.

15 × 6 = ? how many altogether?

90 = the number of seats.

Answer:

Sample Response: First, the variable needs to be determined. Then identify key words and translate the description. If possible, create a model, such as a diagram or table. Then write the equation using the variable.

Answer:

what's the question? I dont see where your coming from.

Answer:

x = 28

Step-by-step explanation:

angle 1 and angle 2 are complementary (their sum is 90°)

x + 5 + 2x + 1 = 90 add like terms

3x + 6 = 90 subtract 6 from both sides

3x = 84 divide both sides by 3

x = 28

Answer:

3 3/4 cubic inches,

Step-by-step explanation:

Stephanie puts 30 cubes in a box. The cubes are 1/2 inch on each side. The box holds two layers with 15 cubes in each layer. What is the volume of the box awnsers 5cubic inches, 7 1/2 cubic inches,3 3/4 cubic inches, 15 cubic inches.

✓From the question we are informed that Stephanie puts 30 cubes in a box. The cubes dimension are 0.5 inch on each of the sides.

✓ Since the sides is 0.5inch each, the volume is (0.5×0.5×0.5) The volume of one cube = (0.5 inch)³ = 0.125 inch³

✓ we can calculate the Volume of 30 cubes as

[ 30 cubes in a box × 0.125 inch³]

= 3.75 inch³

✓ 3.75 inch³ can be converted into fraction as (3 3/4) inch³ which is the third Option.

Answer: 7/8

Step-by-step explanation: 1/2 can be written as 4/8. 4/8+3/8=7/8

Answer:

78 inches

Step-by-step explanation:

From the above question, our final answer is in inches, hence:

1 foot = 12 inches

The widths of the paintings are 10+*inches, 3+*feet, and 2 feet, 2),inches.

For painting 2

Converting 3 feet to inches

1 foot = 12 inches

3 feet = x

Cross Multiply

x = 3 × 12 inches = 36 inches

For painting 3

2 feet, 2,inches.

Converting 2 feet to inches

1 foot = 12 inches

2 feet = x

Cross Multiply

x = 2 × 12 inches = 24 inches

Adding up = 24 inches + 2 inches = 26 inches

If she hangs them next to each other with 3 inches between them, what is the total width of the wall space she will need?

This is calculated as:

10 inches + 3 inches + 36 inches + 3 inches + 26 inches

= 78 inches

Therefore, the total width of space she will need = 78 inches

Answer:

10

Step-by-step explanation:

budget (b) = 600,000

cost per firefighter (c) = 40,000+20,000 = 60,000

total amount of firefighters (t) = b/c

t = 600,000/60,000 = 10

Answer:

z=33 x=90

Step-by-step explanation:

33 X 5 = 165 - 75 = 90 degress and x is a right angle so x is 90 degrees

Answer:

Answer: It will take 199.5 gallons to paint the whole fence.

Step-by-step explanation:

Given:  Paint required to paint [tex]\dfrac47[/tex]of fence = 114 gallons

Then , paint required to paint whole fence = [tex]114\div\dfrac47[/tex]

i.e. paint required to paint whole fence = [tex]114\times\dfrac{7}{4}[/tex]

i.e.  Paint required to paint whole fence= 199.5 gallons

Hence, it will take 199.5 gallons to paint the whole fence.

Answer:

x= 7/3, y= 14/3

Step-by-step explanation:

5x-2x=7

x+y=7

Evaluate 5x-2x=7

5x-2x=3x

3x=7

divide both sides by 3

x=7/3

plug the x value into the second equation

7/3+y=7

subtract 7/3 from both sides

y=7-7/3

evaluate

21/3-7/3=14/3

x= 7/3, y= 14/3

Answer: 55 mph

Step-by-step explanation:

The family plans to drive for 220 miles and would like to do so in 4 hours.

To do so they would need an appropriate average speed.

Formula for speed is:

= Distance / Time

= 220 / 4

= 55 mph

Answer:

They will flash together at;

8:01 PM

Step-by-step explanation:

Here, we want to

calculate the time at which they would both flash together

What we have to do here is to calculate the lowest common multiple of 20

and 30 seconds

Mathematically, we have this as;

60 seconds

60 seconds is the same as 1 minute

So the time they will flash together is 8:01 PM

Answer:

Line A Gradient: 2

Lime B Gradient: -1

Step-by-step explanation:

✔️Gradient for line A using two points on line A, (0, 1) and (1, 3):

[tex] Gradient = \frac{y_2 - y_1}{x_2 - x_1} = \frac{3 - 1}{1 - 0} = \frac{2}{1} = 2 [/tex]

Gradient of line A = 2

✔️Gradient for line B using two points on line B, (5, 0) and (3, 2):

[tex] Gradient = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 0}{3 - 5} = \frac{2}{-2} = -1 [/tex]

Gradient of line B = -1

Answer:

The car must go at 108 km per hour

Step-by-step explanation:

Let us solve the question

∵ A journey by bus takes 45 minutes at 60 km per hour

∴ The speed of the bus = 60 km per hour

∴ The time of the journey = 45 minutes

→ Change the time from minutes to hours

∵ 1 hour = 60 minutes

∴ 45 minutes = 45 ÷ 60 = 0.75 hour

∴ The time of the journey = 0.75 hour

∵ Distance = Speed × Time

→ Substitute the speed by 60 and the time by 0.75

∵ The distance that the bus traveled = 60 × 0.75

∴ The distance that the bus traveled = 45 km

∵ A car goes to do the same journey in 25 minutes

∴ The distance that the car travels = 45 km

∴ The time that the car takes = 25 minutes

→ Divide it by 60 to change it to hours

∵ 25 minutes = 25 ÷ 60 = [tex]\frac{5}{12}[/tex] hour

∴ The time that the car takes =  [tex]\frac{5}{12}[/tex] hour

→ Use the rule of the distance above to find the speed of the car

∵ 45 = the car's speed ×  [tex]\frac{5}{12}[/tex]

→ Divide both sides by  [tex]\frac{5}{12}[/tex]

∴ 108 = the car's speed

∴ The car's speed = 108 km per hour

∴ The car must go at 108 km per hour

Answer:

Step-by-step explanation:

The positive and value of term difference is 5 every time.

Answer:

4.1271

Step-by-step explanation:

Look at the number to the right of the full cents, if the number is five or more, increase the cents by 1. If the number is four or less, keep the cents the same. For example: Round $143.864. Look at the last digit, that is 4, since 4 is less than 5 so keep cents the same.

4.1271

last number is 1 so the cents stays the same

Answer:

1/5

Step-by-step explanation:

[tex]5^{-x}[/tex] = 25 so  x = -2 because [tex]5^{2}[/tex] = 25

if x = -2 then plug in: 5^1/2(-2)  =  5^-1  = 1/5
