Answer:
Train B is going faster than Train A
Step-by-step explanation:
The distance travelled by Train A, d = 80t
The distance travelled by Train B is given as follows;
Time (hours) [tex]{}[/tex] Distance (km)
2 [tex]{}[/tex] 190
4 [tex]{}[/tex] 380
5 [tex]{}[/tex] 475
Therefore, we have that the rate of change of Train B is given as follows;
(475 - 380)/(5 - 4) = 95 km/h
(475 - 190)/(5 - 2) = 95 km/h
The rate of change of Train B = 95 km/h
While the distance covered by Train A per 1 hour, t = 1 is given as follows
Distance covered in 1 hour for Train A, d = 80 × 1 = 80 kilometers
The rate of train A = Distance covered/(Time in which the distance was covered)
The rate of train of change A = 80 km/(1 hour) = 80 km/hour
The rate of train of change A = 80 km/h
Therefore, Train B is going faster than Train A.

Answer:
b
Step-by-step explanation:
express the ratio 60cm to 20m
Answer:
3 cm : 1 cm
Step-by-step explanation:
1. 60 : 20
2. divide 10 on both sides = 6 : 2
3. divide by 2 on both sides = 3 : 1
4. 3 cm : 1 cm
I'm so sorry, I just read the ratio is 60 cm to 20 M
So edit:
convert both into a unit, we'll take m.
1 cm = 100 m
so 60 x 100 = 60000 m
= 60000 m : 20 m
= divide by 20 in both sides...
= 3000 m : 1 m

What is the equation in slope - intercept form of the line that has a slope of 0.25 and passes through the point (6, -8)?
Step-by-step explanation:
y-b=m(x-a)
y--8=1/4(x-6)
y+8=1/4(x-6)
4y+32=1(x-6)
4y+32=x-6
4y=x-38
y=1/4x-38/4
or -x+4y+38=0
or -×+4y= -38

How do you write 7 is subtracted from seven times a number
Penguins can swim at a speed of up to 33 ft./s use dimensional analysis to convert the speed to miles per hour 1 mile equals 5280 feet
Answer:
v = 22.5 miles/hour
Step-by-step explanation:
It is given that,
The speed of Penguins is 33 ft/s.
We need to convert the speed to miles per hour.
We know that, 1 mile = 5280 feet
Speed,
[tex]v=33\ \dfrac{ft}{s}\\\\=33\times \dfrac{\dfrac{1}{5280}\ \text{miles}}{\dfrac{1}{3600}\ \text{hour}}\\\\=22.5\ \text{miles/hour}[/tex]
So, the speed of the Penguins is 22.5 miles/hour.

Which of these expressions is equivalent to -2(x - 5)?
-2x + 5
-2x - 10
-2x + 10
-2x-5
Question 3
Mathematics
The equivalent expression is: -2x + 10. therefore the correct option is C.
What are equivalent expressions?Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.
To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.
From the distributive property;
-2(x - 5)
Then, multiply -2 and -5
-2 * x = -2x
-2 * -5 = 10
because two negatives make a positive
Therefore the answer would be -2x+10.
Hence,The equivalent expression is: -2x + 10. therefore the correct option is C.
