Thirty minutes of exercise per day can reduce your blood pressure. Which of the following is a guideline for establishing causality?
a) Look for evidence that smaller amounts of exercise produces a reduction in blood pressure.
b) Check if lower blood pressure is present or absent when exercise is present or absent
c) Perform a randomized, controlled experiment.
d) Control the number of minutes of exercise and blood pressure to get the same results.
Answer:
perform a randomized, controlled experiment
Step-by-step explanation:
A crew of highway workers paved 1/5 mile in 1/8 hour. If they work at the same rate, how much will they
pave in one hour?
A. 1 and 3/5 miles
B. 1 and 4/5 miles
C. 2 miles
D. 2 and 1/5 miles
Answer:
The easiest approach is to realise that one hour is 3 times longer than 20 minutes. The longer the time, the more they will pave.
215 of a mile, in 20 minutes, how much in 60 minutes?#
They will pave 3 times more.
215×31=615 of a mile
615=25 of a mile
You could also use the 'unitary method' where you find out how much they pave in ONE minute (divide by 20) and them multiply by 60 to find how much in one hour.
Look at what happens:
215÷20×60
=215×120×603
=215×3 ← exactly the same maths.
=25
Which is the simplified form of the expression
Answer: B
Step-by-step explanation:

the sum of three numbers is 66.the second number is twice the first number and the third number is 3x the first number
what is the first and second number?
Answer:
The first number: 11;
The second number: 22;
The third number: 33
Step-by-step explanation:
The first number: 11
The second number: 11 x 2 = 22
The third number: 11 x 3 = 33
11 + 22 + 33 = 66
Answer:
11 and 22
Step-by-step explanation:
let the first number ne x then second is 2x and third is 3x and sum is
x + 2x + 3x = 66 , that is
6x = 66 ( divide both sides by 6 )
x = 11
2x = 2 × 11 = 22
first number is 11 and second number is 22

Give THREE reasons why it is important to revise your study methods
Ken solved the linear equation 2(5y - 1) = 18 using the following steps.
Step 1: 2(5y - 1) = 18
Step 2: 10y - 1 = 18
Step 3: 10y = 19
Step 4: y = 1.9
Which statement is true about Ken's method?
A. Ken made a mistake between Steps 1 and 2.
B. Ken made a mistake between Steps 2 and 3.
C. Ken made a mistake between Steps 3 and 4
D. Ken solved the equation correctly.
Answer:
A
Step-by-step explanation:
in step 1, when expanding the bracket, ken needed to do 2×5y AS WELL as 2×-1 which they didn't do. the correct answer after the first step should be 10y-2=18
Calculate x,y and z fully and give reasons.
Answer:
X=67°,Z=113°,Y=0°
Step-by-step explanation:
2.1=
X+113°=180°(being straight angle)
Or, X=180°-113°
Or,X=67° answer
Now,
Z=113°(being alternative angle)
Again,Y+Z+X=180°(being co-interior angle)
Or, Y+113°+67°=180°
Or,Y+180°=180°
Or,Y=180°-180°
=Y=0° answer
Find out the area and circumference of a circle of diameter 50cm
Step-by-step explanation:
d=2r.
50=2r
r=50/2
r=25cm.
circumference of circle =2πr
=2×22/7×25
=157cm(approx)
area of circle=πr²
=22/7×(25)²
=704cm

What does the function f(x)=/x+1’- 1 have in its range that are not in the range of the graph g(x)?
[-1,1)
(-1,1)
(- infinity, 1]
(- infinity, 1)
Answer:
(-1,1)
Step-by-step explanation:
First split it into 2 functions, when x≥0 let f1(x)=x1+x and when x<0 let f2(x)=x1−x now we have 2 functions that are continuous on their domains.
Solve for x: x + 8 = 15
Answer:

The area of the rectangle is 68 square units. Notice that you can divide the rectangle into two squares with equal area. How can you estimate the side length of each square? Estimate the length and width of the rectangle.
let "L" represent the length of the rectangle
let "W" represent the width of the rectangle
Area of the rectangle = LW
68= LW --------eqn 1
Area of a square = L/2 ×L/2
34= L^2/4
136=L^2
L= 11.67
From eqn 1 , W=68/L
W=68/11.6619
W=5.83
