Two trains started moving at the same time, train A from Boston to New York, and train B from New York to Boston. The distance between the train stations in New York and Boston is 240 miles. The average speed of train A is 60 mph, which is 3 4 of the average speed of train B.
1. How soon will the trains meet
2. How far from New York will the trains meet?
Answer:
------
Step-by-step explanation:
1. The average speed of train A = 60 mph,
The average speed of train B = 60 / 3/4 = 80 mph
Time it takes for trains to meet = 240/(60 + 80) = 240/140 = 12/7 hours
2. The trains meet in 12/7 hours, each traveling at their own speed.
S = D/T, D = S*T
Therefore we can say:
12/7(60) = distance train A is from Boston = 720/7 miles
12/7(80) = distance train B is from New York = 960/7 miles
The distance from New York would = 960/7 miles

Tea bags are sold in three sizes of box. A small box of 50 tea bags costs £2.15 A medium box of 80 tea bags costs £3.29 A large box of 125 tea bags costs £5.17 Which size of box is the best value for money?
Answer:
medium box
Step-by-step explanation:
The computation is shown below:
For small box,
= £2.15 ÷ 50
= £0.043
For medium box
= £3.29 ÷ 80
= £0.041125
And, for large box
= £5.17 ÷ 125
= 0.04136
So as per the above calculation the medium box should represent the best value for the money
How many cubic blocks of side length of 173 inch would it take to fill a rectangular prism with a length width and height of 3/7 inch 1/7 inch and 370
Complete question :
How many cubic blocks of side length of 17 inch would it take to fill a rectangular prism with a length width and height of 3/7 inch 1/7 inch and 3/7 inch
Answer:
9 cubic blocks
Step-by-step explanation:
The volume of a rectangular prism is given as :
V = Length * width * height
V = 3/7 * 1/7 * 3/7 = 9 / 343 in³
The volume of block clube:
Take the cube of the side length :
(1/7)^3 = 1 / 343 in³
Number of cubic blocks required :
Volume of prism / volume of cube
9 / 343 ÷ 1 / 343
9 / 343 * 343 /1 = 9
Hence, 9 cubic cubes are needed to fill the rectangular prism

You want to frost a 13 in. by 9 in. cake that you just baked when you notice your little brother ate a piece right out of the middle. What area of cake is left to be frosted if he ate a 2 in. by 2 in. piece? no links pls :) thanks will give brainliest
Answer:
113 inches
Step-by-step explanation:
13 times 9 is 117 inches (this is the area for the whole cake)
2 times 2 is 4 (this is just the middle)
But since the brother ate the middle you will have to subtract the area of the middle piece from the whole area.
117-4 is 113 so the area now is 113 inches

What is the vertex of the following quadratic equation?
y = 7(x + 5)2 + 4
A. (5,4)
B. (-4,5)
C.(-5, 4)
D. (7,-4)
Answer:
C.(-5, 4)
Step-by-step explanation:
The vertex form of a parabola of this type is:
y = a ( x − h ) 2 + k [1]
where ( h , k ) is the vertex.
Explanation:
Given:
y = 7 ( x + 5 )² + 4 [2]
We can convert equation [2] into the same form as equation [1] by writing
+5 as − − 5 :
y = 7 ( x − − 5) ² + 4 [3]
We observe that the vertex is
( − 5 , 4 )

Answer:
18 boys
Step-by-step explanation:
There is a 3:5 ratio of boys to girls
The ratio we need to find is ?:30
5 times 6 is 30, which means we have to multiply 3 by 6 to find the number of boys
3 times 6 is 18
Two number cubes are rolled.
What is the probability that the first lands on an odd number and the second lands on an even number?
Enter you answer, as a fraction in simplified form, in the box
Answer:
1/4
Step-by-step explanation:
Assuming the number cube is a six-faced die, you have
1 2 3 4 5 6
three odd numbers, and three even numbers. Therefore, the chance of it landing on an odd number or even number is 3/6, which equals 1/2. That means you have a 50% chance to get an odd number, or an even number.
So, you have two die. Both have a 50/50 chance of getting an even or odd number. So what's the chance of one landing on an odd number, and the other landing on an even number?
You would have a 25% chance for an even and then an even numberYou would have a 25% chance for an odd and then an odd numberYou would have a 25% chance for an even and then an odd numberYou would have a 25% chance for an odd and then an even number.25% as a simplified fraction is 1/4. Therefore, 1/4 is your answer.

Step-by-step explanation:
Suppose you are in a building at 28 feet above ground level and you take an
escalator down to ground level. On the escalator, your distance above ground level
changes by - 2 feet per second. Write a linear function to describe the distance d
that
you are from ground level over time t in seconds.
The linear equation that represents the distance (d) above ground level after t seconds is d = -2t + 28
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
The standard equation of a linear equation is:
y = mx + b
Where m is the rate of change (slope) while b is the y intercept.
Let d represent the distance that you are from ground level over time t seconds.
Suppose you are in a building at 28 feet above ground level and you take an escalator down to ground level. On the escalator, your distance above ground level changes by - 2 feet per second. Hence:
d = -2t + 28
The linear equation is d = -2t + 28
