Answer:
562.5 mph
Step-by-step explanation:
First, let's find how fast the car is going in miles per hour. We do this by dividing the miles by how many hours it took:
225/4 = 56.25
The car was going 56.25 mph
A high-speed train is ten times faster than this car so you multiply 56.25 by 10
(10)(56.25) = 562.5
The train's speed is 562.5 mph

using the pythagorean theorem
a^2+b^2 = c^2 where c is the hypotenuse
9^2 +12^2 = x^2
81 + 144 = x^2
225 = x^2
taking the square root of each side
sqrt(225) = x
15 =x
x = 15 inches
Answer:
FORMULA FOR SURFACE AREA OF SPHERE = 4 pi r^2
r = 6 " area = 4 pi X 6 X 6 = 144 pi " squared
r = 12 "
area = 4 X pi X 12 X 12 = 576 pi" squared
ANSWER Area will be 4 times the original
Step-by-step explanation:
The order from least to greatest is 4 7/ 8, 4 9/ 10 , 5
<h3>What are fractions?</h3>
Fractions are simply representatives of part of a whole.
The types of fraction are;
- Mixed fractions
- Simple fractions
- Improper fractions
- Proper fractions
From the information given, we have to arrange in order from least to greatest
5, 4 7/8, 4 9/10
Turn mixed fractions to improper fractions;
5, 39/ 8 , 49/ 10
From least to greatest is written thus;
39/ 8, 49/ 10 , 5
Thus, the order from least to greatest is 4 7/ 8, 4 9/ 10 , 5

Let the integers be x, x+1, and x+2
3(x+x+1)=13+4(x+2)
3(2x+1)=13+4x+8
6x+3=4x+21
2x=18
x=9
the integers are 9,10,11
