A train is traveling at a constant speed and goes 17 kilometers in 8 minutes. How far will the train travel in 60 minutes.

Answers

Answer:

Distance B = 1275 kilometers.

Step-by-step explanation:

Let the two distances and time be A and B respectively.

Given the following data;

Distance A = 17 kilometers.

Time A = 8 minutes.

Distance B =?

Time B = 60 minutes.

First of all, we would find the constant speed;

Speed = distance/time

Substituting into the equation, we have;

Speed = 17/8

Speed = 2.125 km/m

Now, to find the distance B;

Distance B = speed * time

Distance B = 2.125 * 60

Distance B = 1275 km

Which would be an equivalent way to write y= 2 - 3x ?

a) y= -3x - 2
b) y= -3x + 2
c) y= 3x - 2
d) y= 3x + 2

Answers

The answer is B, because the numbers in the equation are 2, and -3x. The signs have to stay with the numbers they are with. So if you move the 3 to the front you have to keep the negative with it.

y^2 + 6y + 9 = 49 factor

Answers

(y+10)(y-4)

Explanation:
In order to solve you must set the equation to 0. Meaning you subtract 49 from 9 to get the original equation to now be y^2+6y-40.
You then set that equation (y^2+6y-40) to zero in order to factor it out.
To do this, you have to find two numbers that multiply to make -40 but add to make 6, which is where you get 10 and -4.

calculate the value of 1/3 a = -5

Answers

Answer:

- 15

Step-by-step explanation:

[tex] \frac{1}{3} a = - 5 \\ \\ a = - 5 \times 3 \\ \\ a = - 15[/tex]

Answer:

-15

Step-by-step explanation:

As you can see, the denominator of 1/3 is 3. 1 third of a is -5. So what you do is, you multiply -5 * 3 and that'll give you -15. So, it is equal to -15.

Step-by-step explanation:

Given values in table :

x        f(x)

3         -1

4          0

5          1

6          2

Here we see there is a difference of 4 in the values of x and f(x)

i.e. 3-(-1)=4

or 4-0=4

Similarly 5-1=4

6-2=4

So x-F(x)=4

Adding F(x) -4 both sides

x-F(x) +F(x) -4=4+F(x) -4

We have F(x)= x-4

it due in a lil bit

Answers

The answer is D. You’re welcome.

Step by step: it’s asking you to find side BD, which is the adjacent to angle B.
And you know the opposite of angle B is AC or 3 inches.

This operation calls for TOA. T stands for Tan, OA stands for Opposite over Adjacent.
So we would do:
tan 60 = 3/x
And then next would be
x = 3/tan 60
Then, you probably have a calculator, so on a calculator do 3 divided by 60 and then press tan and press equal. You will get 1.73 which rounds to 1.7

5x - 4y = -10
y = 2x - 5

y =

Answers

Answer:

x=10

y=15

Step-by-step explanation:

Since we know y in terms of x, we can use substitution and say instead of-

5x-4y=-10

5x-4(2x-5)=-10

5x-8x+20=-10

-3x=-30

x=10

Substitute x into the equation-

y=2x-5

y=2(10)-5

y=20-5=15.

5x - 2y = 4
10x - 2y = 14

Answers

5x - 2y = 4 (1)
10x - 2y = 14 (2)

divide (1) to (2),
-5x = -10
x = 2

Then, to find the y you can substitute the x = 2 to (1),
5(2) - 2y = 4
10 - 2y = 4
- 2y = 4 - 10
- 2y = - 6
y = 3

So, the x = 2 and y = 3

Which measure is of an angle that is coterminal with a 95° angle?

Answers

Answer:

95° - (1,080 n) °, for any integer n

Step-by-step explanation:

Co-terminal angle are those angles who share the same initial side and terminal sides,

And, these angles are obtained by adding or subtracting the multiple of 360°,

That is, if Ф is an angle,

Then its co-terminal angles are,

Ф + 360 n

Where, n is any integer (negative or positive)

Here, Ф = 95°,

Since, n is an integer,

⇒ - 3n is an integer,

Thus, the co-terminal angles of 95° are,

95° + 360° (-3n)

= 95° - (1080 n) °; for any integer n.

Step-by-step explanation:

Hope this helps!~
