Answer:
oof
Step-by-step explanation:
Answer:
There are 200 centimetres in 2 metres. Therefore, 80 centimetres is equal to 80/200 x 100 = 40 percent of 2 metres
First, the biologist must define the variables:
Dependent- this is what will be measured. So the biologist may want to measure the weight and height of the tomatoes, or the leaf area or the time it will produce the fruit.
Independent- this is what will differ in the experiment and what the biologist thinks will affect the dependent variable. In this case, the biologist will use new fertilizer on plant A, old fertilizer on plant B, and no fertilizer on plant C.
Controlled- these variables must be held constant because the biologist doesn’t want other factors to affect the growth of the tomato plant, thus, destroying the purpose of the experiment, tomato plant A, B, and C will have equal amounts of soil, water, and carbon dioxide, and exposure to sunlight.
After his experimentation, he will conclude which of the plant has better weight, growth, leaf, and fruit. If Plant A is the best tomato plant of them all, then he can say that the new fertilizer is more effective.
Answer:
6. 40
7. 65
8. 50 and 80
Step-by-step explanation:
180-70-70=40
180-55-60=65
180-50-50=80 so that would have to be 50+50+80= 180
Becuase it all needs to add up to 180. :))
The equation of the parallel line is y = 
x + 
⇒ 3rd answer
Step-by-step explanation:
Parallel lines has:
- Same slopes
- Different y-intercepts
The slope-intercept form of the equation of a line is y = mx + b, where
- m is the slope of the line and b is the y-intercept
- The formula of m is
∵ Line EF has E (-2 , 5) and F (1 , 3)
∴ 
= -2 and 
= 1
∴ 
= 5 and 
= 3
- Use the formula of m above to find the slope of line EF
∴ 
∵ The line is parallel to line EF
∴ Their slopes are equal
∴ The slope of the parallel line is
- Substitute the slope of the line in the form of the equation
∴ y = x + b
- To find b substitute x and y in the equation by the coordinates
of a point on the line
∵ The parallel line passes through point (2 , 6)
∴ x = 2 and y = 6
∴ 6 = (2) + b
∴ 6 = 
+ b
- Add 
to both sides
∴ = b
∴ y = x +
The equation of the parallel line is y = x +
