Two snakes race the speed of the first is 24 1/2 inches per minute and the speed of the other is 26 inches per minute how far apart with they be in 3 min? 10 min?
Answer:
637, 245
Step-by-step explanation:
Speed is the rate of change in the position of an object. The distance between the two snakes after 10 mins is 15 inches.
What is the relation between speed, distance, and Time?We know that sped, distance, and time all are in a relationship to each other. this relationship can be given as,
[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]
Given to us
Two snakes race The speed of the first is 24 1/2 inches per minute The speed of the other is 26 inches per minute What is the distance between them after 3 mins?The relative speed between them, as they are moving in the same direction, therefore,
Relative speed = (26-24.5) = 1.5 inches per minute
[tex]\text{Distance between them after 3 mins}= \rm speed \times \rm time[/tex]
[tex]= 1.5 \times 3\ mins\\= 4.5\ inches[/tex]
Thus, the distance between the two snakes after 3 mins is 4.5 inches.
What is the distance between them after 10 mins?The relative speed between them, as they are moving in the same direction, therefore,
Relative speed = (26-24.5) = 1.5 inches per minute
[tex]\text{Distance between them after 10 mins}= \rm speed \times \rm time[/tex]
[tex]= 1.5 \times 10\ mins\\= 15\ inches[/tex]
Thus, the distance between the two snakes after 10 mins is 15 inches.

Abby bought 3 sweaters that each cost the same amount and 1 skirt that cost $15. The items she bought cost a total of $90 before tax was added. Determine which equation could be used to find, x, the cost of each sweater.
A 3x - 15 = 90
B 3x + 15 = 90
C 15 - 3x = 90
D 15x + 3 = 90
Answer:
B
x is the price of the sweater so 3x and add $15 for the skirt which would add up to $90
Answer:
3x + 15 = 90

The graph shows the distance, y, in miles, of a moving motorboat from an island for a certain amount of time, x, in hours:
What is the speed of the motorboat?
Group of answer choices
A. 35 miles per hour
B. 70 miles per hour
C. 105 miles per hour
D. 315 miles per hour
Answer: The speed of the motorboat is 70 miles per hour
Step-by-step explanation: Subtract the initial distance, 35, from the distance at any given time, then divide the remainder by the hours.
For example, at 2 hours, the distance shown on the graph is 175 miles
Subtract: 175 -35 = 140. Then divide 140/2 = 70
At 4 hours, the distance shown is 315 miles.
Subtract: 315 - 35 = 280. Then divide 280/4 = 70
70 mph is the speed.

Solve the inequality
what is the solution?
Answer:
The solution to the inequality is:
[tex]2\ge \frac{g}{-4}\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:g\ge \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:[-8,\:\infty \:)\end{bmatrix}[/tex]
Please also check the graph of the solution to the inequality.
Step-by-step explanation:
Given the inequality
[tex]2\ge \frac{g}{-4}[/tex]
switch sides
[tex]\frac{g}{-4}\le \:2[/tex]
Multiply both sides by -1 (reverse the inequality)
[tex]\frac{g\left(-1\right)}{-4}\ge \:2\left(-1\right)[/tex]
Simplify
[tex]\frac{g}{4}\ge \:-2[/tex]
Multiply both sides by 4
[tex]\frac{4g}{4}\ge \:4\left(-2\right)[/tex]
Simplify
[tex]g\ge \:-8[/tex]
Therefore, the solution to the inequality is:
[tex]2\ge \frac{g}{-4}\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:g\ge \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:[-8,\:\infty \:)\end{bmatrix}[/tex]

solving special systems.
Answer:
the system has infinitely many solutions
Step-by-step explanation:
Given the expressions
y - 2x = 4 .... 1
2x -y - 4 = 0 .... 2
We are to find the solution to the equation as shown
From equation 1: y = 4+2x
Substitute into 2:
2x - (4+2x) - 4 = 0
2x - 4 - 2x - 4 = 0
0 = 0
This shows that the equation has infinite number of solutions
Let y = k
Get x
Substitute y = k into equation 2
From 2: 2x -y - 4 = 0
2x - k - 4 = 0
2x = k+4
x = (k+4)/2 where k is any integer
Hence the system has infinitely many solutions

The population of a village is increased from 234 to 275 during one year. Find the percentage increase
Answer:
17.5%
Step-by-step explanation:
Let 234 = 100%
Percentage change = (new/old) x 100
(275/234) x 100 = 117.5213675% = 117.5% (1 d.p.)
117.5% - 100% = 17.5%
