A train leaves at 1314 and arrives at 1508. It travelled at an average speed of 105 km/h.
How far did it travel? Give your answer in km to 1DP
Answers
Answer: The train traveled 199.5 km
Step-by-step explanation:
We know the relationship:
Distance = Time*Speed
We know that the speed of the train was 105km/h
And we know that it leaves at 13:14, and arrives at 15:08.
Then the total amount of time that the train was traveling is:
T = (15 hours and 8 mins) - (13 hours and 14 mins)
= (15 - 13) hours and (8 - 14) mins
= 2 hours and (-6) mins.
We know that one hour has 60 minutes, then this is equal to:
T = 1 hour and 54 minutes.
But because the speed is kilometers per hour, we need to rewrite the 54 minutes in hours.
This can be done as follows:
1 hour = 60 minutes.
Then: 54 minutes = (54/60) hours = 0.9 hours.
Then:
1 hour and 54 minutes = 1.9 hours.
Now we know the speed and the time, then the distance can be calculated as:
Distance = speed*time = 105km/h*(1.9 h) = 199.5 km
The train traveled 199.5 km
Answer:

If f(x)=2x−2 and g(x)=x2−8x+19, then f(x)=g(x) for what values of x?
x=−1 and x=−4
x=−3 and x=−7
x=1 and x=4
x=3 and x=7
Answers
Answer:
D) x =3 and x =7
Step-by-step explanation:
Step(i):-
Given function f(x) = 2x -2
g(x) = x² - 8x +19
Given that f(x) = g(x)
⇒ 2x -2 = x² - 8x +19
⇒ x² - 8x +19 -2x +2 =0
⇒ x² -10x +21 =0
Step(ii):-
The factors are x² -10x +21 =0
⇒ x² - 7x - 3x +21 =0
⇒ x( x-7) -3( x-7) =0
⇒ (x-3)(x-7) =0
x =3 and x =7

Mark wants to make an enclosure for his cows.
He has 44 metres of fencing.
He wants the width to be 8 metres less than the length.
What dimensions should the field have?
?
Answers
Answer:
the length and width be 15 meters and 7 meters respectively
Step-by-step explanation:
The computation of the dimension of the field is given below;
Let us assume the fencing be p
Length be x
And, the width be x - 8
So,
P = 44
P = x - 8 + x - 8 + x + x
= 4x - 16
Now
4x - 16 = 44
4x = 44 + 16
4x = 60
x = 15
And, the width be 15 - 8 = 7
So, the length and width be 15 meters and 7 meters respectively
A farmhouse shelters 14 animals. Some are

Answers

Answer:
8 pigs6 chickensStep-by-step explanation:
Maybe you want to know the number of each kind of animal.
__
We can write two equations in the two unknowns.
p + c = 14 . . . . . . number of animals
4p +2c = 44 . . . number of legs
Dividing the second equation by 2, it becomes ...
2p +c = 22
Then subtracting the first equation gives ...
(2p +c) -(p +c) = (22) -(14)
p = 8
8 +c = 14
c = 6
The farmhouse shelters 8 pigs and 6 chickens.

Westminster Street and Lake Avenue intersect. If Westminster Street is 7 meters wide and Lake Avenue is 5 meters wide, what is the distance between two opposite corners of the intersection? If necessary, round to the nearest tenth.
Answers
Answer:
the distance between two opposite corners of the intersection is 8.60 meters
Step-by-step explanation:
The computation of the distance between two opposite corners of the intersection is given below:
Here we applied the Pythagoras theorem
[tex]= \sqrt{7^2 + 5^2} \\\\= \sqrt{49 + 25} \\\\= \sqrt{74}[/tex]
= 8.60 meters
hence, the distance between two opposite corners of the intersection is 8.60 meters

Let’s use a random equation
(3x-7)(6x+2)
the F stands for “first”... the 3x is first in its parenthesis. The 6x is the first in its parenthesis. So multiply those. You get 18x^2
The O stand for “outer” the 3x and 2 are the outer. They equal 6x.
the I stand for “inner”. -7 and 6x are the inner parts of the equation. They equal -42x
The L stand for last. The last are -7 and 2. They equal-14.
Put it all together
18x^2+6x-42x-14

Angle A and Angle B are complementary. If angle A is 48°, what is the measure of angle B?
Answers
Answer:
B = 42°
Step-by-step explanation:
hope it help
plz fo"ow me
The measure of the angle B when angle A and angle b is complementary angle should be 42 degrees.
Calculation of the measure of angle B:Since
Angle A and Angle B are complementary. And, angle A is 48°.
We know that
The sum of complementary angles is 90 degrees
So it can be like
A + B = 90
48 + B = 90
B = 90 - 48
= 42 degrees
hence, The measure of the angle B when angle A and angle b is complementary angle should be 42 degrees.

Answer:
m = 11, and the correct equation is m + 7.28 = 18.28
Step-by-step explanation:
First, we need to solve:
0.2*m = 2.20
To do it, we need to divide by 0.2 in both sides:
0.2*m/0.2 = 2.20/0.2
m*(0.2/0.2) = 11
m = 11
Ok, we know the value of m.
Now we need to input the value of m in each one of these 4 equations and see which one is the correct one.
The correct equation is;
m + 7.28 = 18.28
When we replace m by 11, we get:
11 + 7.28 = 18.28
So the equation is correct.
