Answer:
The ship arrived at 5 am on Saturday
Step-by-step explanation:
Here, we want to know at what time and day the ship arrive the second port
we simply need to add the time it left the first port and the amount of time the journey took
Mathematically, that will be;
22:45 + 7 1/4
1/4 is same as 60/4 = 15 minutes
So we have;
22:45 + 7:15
= 5 am on Saturday
log (x2 - 1) - log (2x + 2) = 0
Answer:
x=3
Step-by-step explanation:
log (x^2 - 1) - log (2x + 2) = 0
Add log (2x + 2) to each side
log (x^2 - 1) = log (2x + 2)
Since the logs with the same base are equal the x^2 -1 must equal 2x+2
x^2 -1 = 2x+2
Subtract 2x+2 from each side
x^2 -1 -2x-2 = 2x+2 -2x-2
x^2 -2x-3 = 0
Factor
What number multiplies to -3 and adds to -2
-3 *1 =-3
-3+1 =-2
(x-3) (x+1) =0
Using the zero product property
x-3 =0 x+1 =0
x=3 x=-1
Check to see if solutions are valid
x = -1
log ((-1)^2 - 1) - log (2*-1 + 2) = 0
log(0) - log 0 = 0
Log 0 is undefined x =-1 not a valid solution
x = 3
log ((3)^2 - 1) - log (2*3 + 2) = 0
log(8) - log 8 = 0
valid
solve the inequality: 8(7-x)<64
Answer: x>-1
solving For X
Answer:
x > -1
Step-by-step explanation:
8(7-x)<64 (solve for x)
56 - 8x < 64 (distribute!)
-8x < 8 (subtracted 56 from both sides)
x > -1 (divide by -8, flip sign anytime you divide by a negative!)

2 triangles are shown. The first triangle has side lengths x, x, 50. The second triangle has side lengths 45, 45, 75. What value of x will make the triangles similar by the SSS similarity theorem? 1.5 20 30 67.5
Answer:
30
Step-by-step explanation:
yes I can tell what it is
The value of x that will make the two triangles similar by the SSS similarity theorem is: C. 30.
What is the SSS Similarity Theorem?According to the SSS similarity theorem, if all the three corresponding sides of two triangles are proportional or have the same ratio, then both triangles are similar.
If the two triangles are similar we would have:
75/50 = 45/x
Cross multiply and find x
x = (45 × 50)/75
x = 30
Thus, the value of x would be: C. 30.

The ratio of band students to choir students is 4:6. There are a total of 60 students in the band and choir. How many students are in the band?
Answer:
24
Step-by-step explanation:
Given that:
The ratio of band students to choir students is 4 : 6.
Total number of students in the band and choir combined = 60
To find:
The number of students in the band = ?
Solution:
First of all, let us understand the meaning of the ratio given.
Ratio of 4 : 6 means there are 4 number of band students for every 6 number of choir students.
Also, number of band students will be in the multiples of 4 only and
number of choir students will be in the multiples of 6 only
Let the total number of band students = 4[tex]x[/tex]
Let the total number of choir students = 6[tex]x[/tex]
Total number of students = 60
As per question statement, we can write the following equation:
[tex]\Rightarrow 4x+6x=60\\\Rightarrow 10x = 60\\\Rightarrow x =6[/tex]
Total number of band students = 4 [tex]\times[/tex] 6 = 24

A ,B and C average is 45 ,b and C average is 40 then find b
This question is incomplete
Complete Question
The average weight of A, B and C is 45 kg. If the average weight of A and B be 40 kg and that of B and C be 43 kg, then the weight of B is :
Answer:
31 kg
Step-by-step explanation:
From the above question:
A ,B and C average is 45.
Hence, the total values of A, B, C is calculated as:
A + B + C /3 = 45
A + B + C = 45 × 3
A + B + C = 135
Also,
B and C average is 43
The total values of B, C is calculated as:
B + C /2 = 43
B + C = 43 × 2
B + C = 86
A and B average is 40
The total values of A, B is calculated as:
A + B /2 = 40
A + B = 40 × 2
A + B = 80
Hence:
A + B + C = 135
B + C = 86
A + B = 80
Hence, we can solve for A, we substitute 80 for A + B
80 + C = 135
C = 135 - 80
C = 55kg
B + C = 86
B + 55 = 86
B = 86 - 55
B = 31 kg
