A snail climbs to the top of a coconut tree 18 meters high. In an hour it will climb 2 meters. But if it go 2 meters, it will slips down one meter. Then how long does it take for the snaik to reach the top of the coconut?
Answers
Answer:
The snail will reach the top of the coconut in 18 hours.
Step-by-step explanation:
If the snail will climb 2 meters in 1 hour but it will slip down one meter for every 2 meters climbed, then the distance traveled will be:
[tex] d = 2 m - 1 m = 1 m [/tex]
Since in 1 hour, it climbs 2 meters minus 1 meter, the time in which the snail will reach the top is:
[tex] t = \frac{1 h}{1 m}*18 m = 18 h [/tex]
Therefore, the snail will reach the top of the coconut in 18 hours.

How much did it rain on Tuesday?
Answers
Answer:0.38 inch
Step-by-step explanation: If it rains 0.72 inch on Monday and on Tuesday it rains 0.34 less inch then, you would have to subtract them to get 0.38 inch aka answer.
Answer: The answer is 0.38 inches
Step-by-step explanation:
The question said that on Tuesday, it rain 0.34 less than on Monday which mean to subtract. Therefore, 0.72-0.34=0.38 inches.

Answers
Answer:
Cost of one CD = $9.98
Step-by-step explanation:
Total cost = $214.60
Total shipping and handling fee = $15.00
Number of CDs = 20
Cost of 20 CDs = Total cost - Total shipping and handling fee
= $214.60 - $15.00
= $199.60
Cost of one CD = $199.60 / 20
= $9.98
Cost of one CD = $9.98
Answer:
$9.98

what is the equation of a line that is perpendicular to the line whose equation is Y=3/5x-2 and that passes through the point (3,-6)?
Answers
The equation of the line that is perpendicular to the line whose equation is Y=3/5x-2 and that passes through the point (3,-6) is; y=-5/3x-1
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
Where x₁ - x coordinate, y₁ - y coordinate, m - slope
Point (3,-6)
Then perpendicular line whose equation is Y=3/5x-2
Slope m = -3/5
Now Write the equation as;
y=-5/3x-1
Hence, the equation of the line that is perpendicular to the line whose equation is Y=3/5x-2 and that passes through the point (3,-6) is; y=-5/3x-1

PLEASE HELPPP!!!Which function passes through the points 2,15 and 3,26?
Answers
Answer:
B. y = 11x - 7
Step-by-step explanation:
first we find the slope by using the formula
[tex]m = \frac{y_{2} -y_{1} }{x_{2}-x_{1} }[/tex]
Now let (2,15) be [tex](x_{1}, y_{1} )[/tex] , and (3, 26) be [tex](x_{2} , y_{2} )[/tex]. So now the slope is equal too.....
[tex]m = \frac{y_{2} -y_{1} }{x_{2}-x_{1} }= \frac{26 - 15}{3-2} = \frac{11}{1} = 11[/tex]
Now we use the slope-point form of the equation and obtain the following....
[tex]y - y_{1} = m(x - x_{1} )\\y - 15 = 11(x - 2)\\y - 15= 11x -22\\y = 11x - 22 + 15\\y = 11x - 7[/tex]

Dave found the blueprint of his house. It shows the hallway is 4 inches long. If the scale factor is 1 inch: 1.25 feet, then what is the length of the hallway in real life?
Answers
Answer:
5 feet
Step-by-step explanation:
The scale factor = 1 inch: 1.25 feet
The length of the Hally = 4 inches
The length of the hallway in real life is calculated as:
1 inch = 1.25 feet
4 inches = x feet
Cross Multiply
x feet = 4 × 1.25 feet
x feet = 5 feet
Therefore, the length of the Hallway in real life is 5 feet

The rate of change in the population of the Siberian tigers loses 65% every two years.
What is an exponent?Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. X is the base and n is the power.
Bozena is an ecologist who studies the change in the tiger population of Siberia over time. The relationship between the elapsed time t, in years, since Bozena started studying the population, and the number of tigers, N(t), is modeled by the following function:

An isosceles triangle has angle measures of (2x degrees) and (5x degrees). What are three possible angle measures of the triangle? Show all work.
Answers
Answer:
[tex]40^{\circ},\:40^{\circ},\: 100^{\circ}[/tex]
Step-by-step explanation:
The interior angles of any triangle always add up to [tex]180^{\circ}[/tex]. In an isosceles triangle, (at least) two sides are congruent and therefore their base angles are also congruent. We can then form the following equation:
[tex]2x+2x+5x=180[/tex], where [tex]x[/tex] is some constant.
Solving, we get:
[tex]9x=180,\\x=20[/tex]
Therefore, plugging our constant back in, our angles are:
[tex]2(20),\: 2(20), \: 5(20), \\\fbox{$40^{\circ},\:40^{\circ},\: 100^{\circ}$}[/tex].
Note this is only one group of possible angles. We could've also set the angle represented by [tex]5x[/tex] to be the pair of angles that are congruent, and depending on your definition of isosceles, each angle measure could be [tex]60^{\circ}[/tex] (equilateral).
Answer:
100, 40, 40
Step-by-step explanation:
First, do 2x+2x+5x because an isosceles triangle has two equal angles. We know that a triangle's total angle is 180 degrees so we do 180/9=20 x=20. Then multiply 2 by 20 to get 40. Then multiply 5 by 20 to get 100. So you get 40 40 100.
