Answer:

<u>Defining Variables:</u>

Let the number of days the snail takes to climb = x days

Total distance climbed in x days = x*4

Total distance slipped in x days = 2*x

<u>Solving for the number of days:</u>

Since the total distance the snail climbs is 20ft (depth of well)

The total distance climbed - total distance slipped = 20

replacing the variables

4x - 2x = 20

2x = 20

x = 10

Therefore, it will take the snail 10 days to reach the top

notsponge [240]
If Paul mows the lawn once, he earns 1*25.50.  If he mows it twice, he earns 2*25.50, and so on.  So, he earns L*25.50.  But, he spends 3.50.  So the equation is:

L*25.50-3.50

Persons taking a​ 30-hour review course to prepare for a standardized exam average a score of 620 on that exam. Persons taking a
mihalych1998 [28]

Answer:

y = 4.125x + 496.25

Step-by-step explanation:

Set the data up as points. Then deal with the points.

Givens

(30,620)

(70,785)

y2 = 785

y1 = 620

x2 = 70

x1 = 30

Formula

Slope = (y2 - y1) / (x2 - x1)

Solution

Slope = (785 - 620)/(70 - 30)

Slope = 165 / 40

Slope = 4.125

===================

Now you need the y intercept. Either one of the two given points will give you that.

y = 620

x = 30

m = 4.125

y = mx + b

620 = 4.125*30 + b

620 = 123.75 + b

620 - 123.75 + b

b = 496.25

Landon used a semicirce, a rectangle, and a right triangle to form the figure shown.
ankoles [38]
Area of rectangle= base x height
6x4=24

Area of triangle= 0.5 base x height
We have the height but we don’t have the base, to calculate the base we subtract 10-6 which equals to 4
0.5 x 4 x4 =8

Area of a semicircle= o.5 x pi x r^2
We have the diameter and to find the radius we divide it by 2
4/2 = 2
0.5 x pi(or 3.14) x 2^2
=6.28
Total area = 24 + 8+ 6.28 =38.28cm^2
