Answer:
2.36
Step-by-step explanation:
order of operations : pemdas
parenthesis, exponents
multiplication, division
addition, substraction
first parenthesis, so
(32-4) = 28
parenthesis again
[10+28] = 38
now you have
90/38 = 45/19 = 2.36
Answer:
2/6

It would take 2 hours. To complete the whole lawn you would need:

To make a whole, so to get that we multiply:

So we use the same number required for the whole lawn, and multiply it times the hours
Expression is 900 - 75n
Step-by-step explanation:
- Step 1: Maximum watts that can be used is 900W. Find amount of watts used by n light bulbs.
⇒ Watts used by n light bulbs = 75 × n = 75n
- Step 2: To find the remaining amount of wattage, subtract the maximum possible W and the watts used by the light bulbs.
⇒ 900 - 75n
Answer:
The answer is "Construct a circle from point R with the radius RP".
Step-by-step explanation:
Please find the diagram to this question in the attached file.
In this question, the line is perpendicular to the PQ and the bisector perpendicular to the PQ throughout the given diagram, and in the next section, it draws the tangent through point A to the circle by drawing 'Draw a circle with radius RP through point R. It circle crosses that given circle P in 2 points. Its tangents could only be achieved with any of these new points by adding point Q.
