8[2(3)-3)
=8[6-3]
=8(3)
=24
If this is the correct equation then this should be the right answer:
3(3)+2
=9+2
=11
Answer: 18°
Step-by-step explanation:
Complementary angles are the angles that when we add them together, the value will equal 90°.
In this question, we've to add both angles and equate them to 90°. This will be:
(2x - 4) + (5x + 17) = 90
2x - 4 + 5x + 17 = 90
Collect like terms
2x + 5x = 90 + 4 - 17
7x = 77
x = 77/7
x = 11
Angle A will be:
= (2x-4)
= 2(11) - 4
= 22 - 4
= 18°
Answer:
3/2 im oretty sure thats the answer
Answer:
5 gallons per week
Step-by-step explanation:
He uses 1.25 gallons per 5 hrs
How many times does he use a full tank in a week?
20/5 =<u> 4 times</u>
To find the total amount of fuel used take 1.25 times 4
1.25 * 4 = 5 gallons
This is the general formula for circle.
x² + y²=r²<span> ,where r is the radius
</span>
Consider the building as the centre of the circle, then the radius is equal to the furthest distance between <span>you and the tower that allow you to have coverage.
Hence,
r</span>² = 2025
r=√2025 = 45 miles
