Answer:

Step-by-step explanation:

Average speed = distance/time

Trip to dry dock

Let x be the velocity

Time = 2hours

Distance = average speed ×time

Distance = x×2

Distance = 2x

Return trip

Velocity = x-5 (5 miles per hour faster on the trip there than on the return trip)

Time = 3hrs

Distance = 3(x-5)

Since the distance is the same both to and fro;

2x = 3(x-5)

2x = 3x -15

2x-3x = -15

-x = 15

x = 15

Hence the aircraft carrier's average speed on the outbound trip is 15miles/hour

Answer:

The answer is

[tex] \huge y = 5[/tex]

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

where

m is the slope

( x1 , y1) is the point

From the question the point is (3,-5) and slope 0

We have

[tex]y + 5 = 0(x - 3) \\ y + 5 = 0 \\ y = 5[/tex]

We have the final answer as

[tex]y = 5[/tex]

Answer:

Given: An Angle in the figure is right angle. Its measure = 90°

So,

∠2 = 90° ( vertically opposite angles are equal )

∠1 + ∠2 = 180° ( Linear Pair )

∠1 = 180 - 90

∠1 = 90°

So, ∠1 and ∠2 are

Right angles because measure of both angles are 90°.

Adjacent angles because both a common arm and a common vertex.

Supplementary angles because sum of both angles is 180°.

Answer:

The equation to solve for x is 8x - 14 = 5x + 34

The value of x is 16

Step-by-step explanation:

Let us use the angles between the parallel lines to find x

∵ Lines l and m are parallel

∴ ∠(8x - 14)° and ∠(5x + 34)° are alternate exterior angles

∵ The alternate exterior angles are congruent

∴ ∠(8x - 14)° ≅ ∠(5x + 34)°  

→ Equate them

∴ 8x - 14 = 5x + 34

∴ The equation to solve for x is 8x - 14 = 5x + 34

Let us solve it to find x

∵ 8x - 14 = 5x + 34

→ Subtract 5x from both sides

∵ 8x - 5x - 14 = 5x - 5x + 34

∴ 3x - 14 = 34

→ Add 14 to both sides

∴ 3x - 14 + 14 = 34 + 14

∴ 3x = 48

→ Divide both sides by 3 to find x

∴ [tex]\frac{3x}{3}=\frac{48}{3}[/tex]

∴ x = 16

∴ The value of x is 16

Answer:

it is parallel

Slope is also known as the gradient of a line. The number of blocks that Teddy is weighing is 20 blocks per pound.

A slope is also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line. It also tells us the rate between the two given quantities.

As the graph is given to us and we need to find the number of blocks teddy is putting per pound, therefore, we need to calculate the rate of the graph also known as the slope of the graph, therefore, using any of the two points to calculate the slope of the graph,

[tex]{\rm Point1} : (x_1, y_1) = (0, 0)\\\\{\rm Point2} : (x_2, y_2) = (5, 100)[/tex]

We know that the slope of the line is given as,

[tex]\text{Slope of the line} = \dfrac{y_2-y_1}{x_2-x_1}[/tex]

Substitute the values,

[tex]\text{Slope of the line} = \dfrac{100-0}{5-0} = \dfrac{100}{5}=20[/tex]

Hence, the number of blocks that Teddy is weighing is 20 blocks per pound.

Molly’s monthly payment by using the Bankrate calculator is $286 per month.

It is given that

The downpayment Molly has = $2500.

Interest rate APR = 1.9%

Cash allowance by dealer = $500

Selling price = $25,495

Loan tenure N= 7 years

Amount of loan needed = 25495-2500-500 = $22495

An equated monthly installment (EMI) is a set monthly payment provided by a borrower to a creditor on a set day, each month.

The EMI or monthly payment will be calculated by the following formula,

[tex]EMI = \frac{P.\frac{APR}{12} .(1+\frac{APR}{12})^N }{(1+\frac{APR}{12})^N-1 }[/tex]

Put APR =0.019(decimal value of APR)

Answer:

y= -x/4 +7

Step-by-step explanation:

x+4y−28=0

Subtract x from both sides. Anything subtracted from zero gives its negation.

4y−28=−x

Add 28 to both sides.

4y=−x+28

The equation is in standard form.

4y=28−x

Divide both sides by 4.

4y/4 = 28−x/4

Dividing by 4 undoes the multiplication by 4.

y= 28-x/4

​

Divide −x+28 by 4.

y= -x/4 +7

Answer:

speed is 0.01 miles per minute

Step-by-step explanation:

We know speed = distance/time

since we need speed in miles per minute we need to convert KM into miles

and hours in minutes

--------------------------------------------------------

distance = 5 km

1 km = 0.621371 miles

5KM = 5*0.621371 miles = 3.10686 miles = 3.12 miles(rounded to nearest hundredth)

1 hour = 60 minutes

4.5 hours = 4.5*60 minutes = 270 minutes

speed = distance in KM/time in minutes = 3.12 miles/270 minutes

speed = 0.012 miles per minute

rounding the answer to  the nearest hundredth

speed is 0.01 miles per minute
