The sum of the speeds of two trains is 724.3 miles per hour. If the speed of the first train is 11.7 mph faster than that of the second train, find the speeds of each.
Answer:
A=368 miles
B= 356.3 miles
Step-by-step explanation:
Given data
Let the two trains be A and B
A+B=724.3----------1
A-B=11.7--------------2
From eqn 1
A= 724.3-B
put this in place of A in eqn 2
724.3-B-B= 11.7
724.3-2B= 11.7
724.3-11.7= 2B
712.6=2B
B= 712.6/2
B= 356.3 miles
Put B=356.3 in eqn 1
A+356.3=724.3----------1
A= 724.3-356.3
A=368 miles

180x - 30 = 1050
180x = 1020
x = 5.67
Find the value of x.
Answer:
x + 42 + 58 = 180x + 100 = 180x = 80°Answer:
x = 80°
Step-by-step explanation:
The measure of the angles of the inside of a triangle, when added result in 180°
58° + 42° + x = 180°
x = 180° - 42° - 58°
x = 80°

Answer:
A & C & F
Step-by-step explanation:
i did this just now i got it right!
Answer:
Step-by-step explanation:
The square root of 9 is 3, while the square root of 4 is 2
3 x 2 = 6
So
A is true
B is true
C is true because we can multiply the two terms of the root and mantain the same root. In fact √36 = 6
D is wrong because the result of the expression is not 6
E is wrong for the same reason of D
F wrong because the result of the expression is 12
If p p and q q vary inversely and p p is 14 when q q is 12, determine q q when p p is equal to 84.
Answer:
q = 2
Step-by-step explanation:
p α 1/q
p = k/q
Where, k = constant of proportionality
p = 14 ; q = 12
We can obtain the value of k
p = k/q
14 = k/12
k = 14 * 12
k = 168
p = 168/q
pq = 168
q = 168 / p
Value of q, when p = 84
q = 168 / 84
q = 2

The pair of points is on the graph of an inverse variation. Find the missing value.
(2.4, 3) and (5, y)
A. 1
B. 1.44
C. 6.25
D. 0.69
Answer:
Step-by-step explanation:
In verse variation would be 3 = k / 2.4 so k = 7.2
So we have y = 7.2 / 5 = 1.44
Answer is 1.44.
Answer:
Hence, the value of y is:
1.44
Step-by-step explanation:
It is given that:
The pair of points is on the graph of an inverse variation.
(2.4, 3) and (5, y)
We have to find the missing value y in the point.
As we know that in the inverse variation the value of y is the inverse value of x by some k.
i.e. in first point (2.4,3) let 'k' be a number such that:
Hence, the inverse is k=7.2
Now in the second point (5,y) we find the value of y as:
Hence, the value of y is:
1.44
Variation can be direct, inverse, joint or combined.
The missing value of y is (b) 1.44
The points are said to represent inverse variation.
So, we have:
[tex]x_1 \times y_1 = x_2 \times y_2[/tex]
Substitute x and y values in the equation
[tex]2.4 \times 3 = 5\times y_2[/tex]
Multiply 2.4 and 3
[tex]7.2= 5\times y_2[/tex]
Divide both sides by 5
[tex]1.44 = y_2[/tex]
Rewrite as:
[tex]y_2 = 1.44[/tex]
Hence, the missing value of y is (b) 1.44

Answer: 534
Step-by-step explanation:
an=a1+(n-1)d
Here,
d is the common difference
=>a2-a1=12-3=9
& a1=3
a60=3+(60-1)9
a60=3+(59)*9
a60=3+531
a60=534
60th term is 534.
Answer:
60th term = 534
Step-by-step explanation:
The easier way:
3 + (60 -1) (9)
3 + (59) (9)

8) The volume of a cuboid 12cm long 9 sm broad and 6 cm high is
a) 648 cm
b) 648 m
c) 648 cm
d) 648 m
Answer:
648 cm³
Step-by-step explanation:
For Cuboid
l = 12cm
b = 9cm
h = 6cm
Now, The volume of a cube is
l × b × h
12 × 9 × 6 cm
108 × 6 cm
648 cm³
Thus, The volume of a cuboid 12cm long 9 sm broad and 6 cm high is 648 cm³
