help me solve -2/7x -5=-13 and please add how to do it​

Answer:

The distance from the plane to the building is ___2553.2___meters.

Step-by-step explanation:

Given that An airplane is at an altitude of 1200 m.

The angle of depression to a building at the airport on the ground measures 28°.

We need to find the distance from the plane to the building.

Please check the attached diagram.

Let 'x' be the required distance in meters.

It forms a right-angled triangle as shown in the attached diagram.

The angle = Ф =  28°

The opposite to angle = 1200 meters

All we need to find the hypotenuse to determine the distance from the plane to the building.

Using the trigonometric ratio

sin θ = Perpendicular ÷ Hypotenuse

sin (28°) = 1200 ÷ x

x = 1200/sin (28°)

  = 1200 / 0.47         ∵ sin (28°) = 0.47

   = 2553.2 m

Thus, the distance from the plane to the building is ___2553.2___meters.

Answer:

86

Step-by-step explanation:

This is because the angles should add up to 180. So 32 + 64 is 96. Then you subtract 96 from 180 to get 86.

Grace will pay $7 for a student ticket.

Let's write the cost of a student ticket as "S." The price of an adult ticket, according to the information provided, is equal to the cost of a student ticket plus $8. Therefore, this relationship can be expressed as an equation:

Price of adult ticket = Price of student ticket + $8

Since the price of an adult ticket is $15 and the price of a student ticket is "S," the equation becomes:

$15 = S + $8

We now need to separate "S" on one side of the equation in order to figure out how much Grace will pay for a student ticket ("S"). To accomplish this, take $8 away from either side of the equation as follows:

$15 - $8 = S

$7 = S

Answer:

1 week 2 inches

Step-by-step explanation:

Pretty self explanatory

so we started with 4cm and by week 3 its 10cm.

So since the 4cm doesn’t count toward the 10 cm since it was already there, that turns it into 6 becuase 10-4 is 6. So 3 weeks, 6 inches, find the unit rate by dividing 6 and 3 and you’ll get 2, so 2 inches every week, now to check they gave us another week which is by 6 weeks, its 16 cm tall, now remember to subtract the 4, so 12, 12/6=2. So 2 inches every week.

DOUBLE CHECK:

So 6 weeks in total, thats 12cm  becuase each week is 2cm 6*2=12. Add the 4 from the beginning, it’s 16

TRIPLE CHECK

make equation:

X for growth each week

6*x+4=16

You’ll get 2

Step-by-step explanation:

Answer:

1. {12,0}

hope it helps.

Answer:

3 and 4

Step-by-step explanation:

X - 9y = 12     If x=3 and y=-1

3 - (9*-1) = 12

3 +9 = 12

12 = 12

and

X - 9y = 12     If x=0 and y=-4/3

0 - (9 * -4/3) = 12

0 + 12 = 12

12 = 12

We need to know about translation along vector to solve the probelm. The coordinates of the figure after translation along the vector (5,-4) are (2,-4), (3,0) and (4,-4).

Translation means moving an object from one place to another. Every point on the object moves the same amount of distance and in the same direction. Translation of a point along a vector means moving the point to a different location with respect to the given vector. Here we have three points which form a triangle JKL, we have to translate triangle JKL with respect to the vector (5,-4) to get triangle QRS. Inorder to translate a point along a vector we add the x-coordinate of the vector to the x-coordinate of the point and same for the y-coordinates.

J (-3,0)    Q (-3+5,0-4)≡(2,-4)

K (-2,4)    R (-2+5,4-4)≡(3,0)

L (-1,0)     S (-1+5,0-4)≡(4,-4)

Therefore we get the coordinates of triangle QRS after translation of triangle JKL along vector (5,-4) to be (2,-4), (3,0) and (4,-4)

Answer:

Step-by-step explanation:

The first one

Answer: 4√2

square root of a number is the factor that we can multiply by itself to get that number.

The square root symbol is also called as a RADICAL.

Perfect squares are the squares of the integers also called as square numbers.

to find the square root of non-perfect squared numbers we have to check the number with a near-perfect squared numbers

how to find square root of non perfect squared numbers:

If we can't figure out what factor multiplied by itself will result in the given number, we can make a factor tree.

Factor tree of 32 = 2*2*2*2*2

                            = (2*2) * (2*2) *2

                            = (4)2 *2

Therefore √/32 = √/2*2*2*2*2

                          = √/(4)2*2

                          = 4√/2

Answer:

2/16 I think

Step-by-step explanation:

if she only wants two apples and there is a total of 16 peices of fruit in the bowl she has a 2/16 chance she will get an apple

The probability she will choose two apples is 7/30.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

Total Apple= 8

Total Oranges= 8

So, on the first pick the probability of getting Apple

= 8/16

Now, in second pick the number of apple remained = 7

So, the probability of getting apples on second pick

= 7/ 15

So, the probability she will choose two apples

= 8/16 x 7/15

= 7/30.

Both companies will charge the same cost for renting the truck for 50 miles.

Given that

Declan is moving into a college dormitory and needs to rent a moving truck.

For the type of truck he wants, Company A charges a 30$ rental fee plus $0.95 per mile driven,

Company B charges a 45$ rental fee plus $0.65 per mile driven.

To find

How many miles is the cost of renting the truck the same at both companies?

So, according to the question

we have,

Charges of company A

For rent = $30

For drive = $0.95 per mile

Total cost charges by company A = 0.95(The total distance traveled by truck) + 30

Charges of company A

For rent = $45

For drive = $0.65 per mile

Total cost charges by company A = 0.65(The total distance traveled by truck) + 40

Let's assume The total x miles distance traveled by truck is produced same cost for both companies.

So, we can say that

     Total cost charges by company A = Total cost charges by company B

Now, putting the all given values

We will get,

 0.65(x) + 45 = 0.95(x) + 30

 0.65x + 45 = 0.95x + 30

0.95x - 0.65x = 45 - 30

0.3x = 15

x = 15/0.3

 x = 50

At 50 miles is the cost of renting the truck the same at both companies
