Find the slope of the line that contains the points (1, 6) and (10, -9)
Answer:
-15/9
Step-by-step explanation:
The slope is the steepness of the line. To find it, you divide how far up it goes by how far across it goes. This equals the diagonal incline. To find it with points, you find the difference between the y values and divide that by the difference in the x values!
-9-6=-15
10-1=9
-15/9=-15/9
This slope means that for every nine units the line goes across, it goes down 15 units!

Step-by-step explanation:
Ahmed wrote two numbers.The first number has 7 in it's tenth place.The second number has a 7 with a value that's 1,000 times greater than the value of the 7 in the first number.This is how we can represent it:
*The symbol 'x' represents the numbers that we don't know.
7xx.7
The first 'x' has a place value of ones.
The second 'x' has a place value of tens.
And the second number (7) has a place value of hundreds.

Answer: y = 6x + 2
Step-by-step explanation:
Slope: 8 - 2 / 3 - 0 = 6/1 = 6
y-intercept = 2
Slope intercept formula: y = mx + b
m = slope
b = y-intercept
y = 6x + 2

The water content of a soil volume is measured four times gravimetrically by oven drying. The mean value of the water content is 23.2%. If the standard deviation of the four measurements is 1.0%, the 99% confidence interval for the soil water content is most nearly:________.
A. (19.5%, 26.9%)
B. (18.6%, 27.8%)
C. (20.6%, 25.8%)
D. (20.9%, 25.5%)
99% confidence interval for soil water content is approx : A (19.5%, 26.9%)
Given : Mean x' = 23.2% = 0.232 , Standard Deviation s = 1% = 0.01 , Confidence Limit = 99%
Confidence Internal = x' + t ( s / √n)
t at 99% confidence limit, ie 1% ( 0.01 ) critical value
t at 0.01/ 2, for two sided = t 0.005 = 7.4534
0.232 + 7.4534 ( 0.01 / √4 )
= 0.232 + 0.03736
= ( 0.232 + 0.03736 , 0.232 - 0.03736 )
= 0.19474 , 0.26926
= 19.5% , 26.9%

ON wednesday Eddy goes to a velodrome to train. He cycles the first lap of the track in 25 seconds. Each lap Eddy cycles takes him 1.6 seconds longer thatn the previous lap.
Required:
a. Find the time in seconds, Eddy takes to cycle his tenth lap 2
b. Eddy cycles his last lap in 55.4 seconds. Find how many laps he has cycled on wednesday.
c. Find the total time in minutes, cycled by Eddy on Sunday.
Answer:
Step-by-step explanation:
The data of timing for each lap will form a arthmetic progression ( AP ) with first term as 25 s and common difference of 1.6 s .
a )
first term a = 25
common difference d = 1.6 .
10 th term of the series can be given by following formula
a₁₀ = 25 + ( 10-1 ) x 1.6
= 25 + 1.6 x 9
= 39.4 s
b )
Let n th be the last lap
a(n) = a + ( n-1 ) x d
55.4 = 25 + ( n- 1 ) x 1.6
n - 1 = 19
n = 20 .
c )
sum of all the term of AP
=( first term + last term ) x no of term / 2
= (25 + 55.4 ) x 20 / 2
= 804 s .
= 804 / 60 min
= 13.4 min .

Together a chair, a table, and a lamp cost $562. The chair costs 4 times as much as the lamp, and the table costs $23 less than the chair. Find the cost of the table.
Answer:
Cost of table is $237
Step-by-step explanation:
Cost of chair, table and lamp = $562
Cost of lamp = x
Cost of chair = 4x (The chair costs 4 times as much as the lamp)
Cost of table = 4x-23 (the table costs $23 less than the chair.)
We need to find the cost of table.
We know that:
Cost of chair, table and lamp = $562
We can write:
[tex]x+4x+4x-23=562[/tex]
First, we need to find value of x by solving the equation.
[tex]x+4x+4x-23=562\\9x=562+23\\9x=585\\x=\frac{585}{9}\\x=65[/tex]
So, we get x = 65
Now, we can find cost of table:
We are given:
Cost of table = 4x-23
Cost of table = 4(65)- 23 = 237
So, Cost of table is $237

Answer:
1 round = 220 meter wire
2 rounds = 440 meter wire
3 rounds = 660 meter wire
Step-by-step explanation:
Given that:
Perimeter of squared garden = 220m
As the perimeter is given, the length of the wire would be calculated with it.
The length of wire to fence with 1 round = 220 * 1 = 220m
The length of wire to fence with 2 rounds = 220 * 2 = 440m
The length of wire to fence with 3 rounds = 220 * 3 = 660m
Hence,
1 round = 220 meter wire
2 rounds = 440 meter wire
3 rounds = 660 meter wire
