Answer:
8x + 20y = 5
Step-by-step explanation:
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
given
y = - 0.4x + 0.25 ( multiply all terms by 20 to eliminate fractions )
20y = - 8x + 5 ( add 8x to both sides )
8x + 20y = 5 ← in standard form
Hi There!
Step-by-step explanation:
4.2 + 3 = 7.2
7.2 * 1.75 = 12.6
Answer:
Harold spent $12.60 on apples.
Hope This Helps :)
The actual dimension of the sail are 6 m tall and 4.5 m wide.
The model is 20 cm tall. First we need to find the ratio which Kendall used in his model.
6 meters of actual length is represented in model by 20 cm.
6 meters of actual length is represented in the model by 0.2 m.
1 meter of actual length is represented in the model by 0.2/6 = 1/30 meters
So, the ratio of actual measure to model measure will be:
1 : 1/30
or
30 : 1
The actual width of the sail = 4.5 meters
The width of the sail in the model will be = 4.5 x 1/30 = 0.15 m = 15cm
So, the dimensions of the sail in the model will be 20 cm tall and 15 cm wide.
Answer: The derivative would be 
Step-by-step explanation:
Since we have given that
As we will use "Chain Rule"
and at last we will use the identity ''
''
We need to find the derivative of the function:
Hence, the derivative would be
To perform the correct operation as to subtract numbers, make sure the denominators are the same, and then one can then subtract and remove a smaller number from the larger one.
This same method also holds true for adding fractions together as well.
Another way to subtract fractions is to convert them from fraction form to decimal form and then align the decimal points and subtract the values.
