Answer: x = 38°
Steps:
The little square in the corner tells us that the angle is 90°
x + 52 = 90
x = 90 - 52
x = 38°
Check:
x + 52 = 90
52 + 38 = 90
90 = 90 ✅
If this was helpful and correct I would appreciate the brainliest! :)
Let 2_1/2 = 5/2.
Let t = time to fill 8 tires
(5/2)/8 = (5/2)/t
8(5/2) = (5/2)t
20 = (5/2)t
20 ÷ 5/2 = t
20 • 2/5 = t
8 seconds = t
Done.
Answer:
x = 30
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , thus
x + 4x + 30 = 180
5x + 30 = 180 ( subtract 30 from both sides )
5x = 150 ( divide both sides by 5 )
x = 30
To model this, I would use a 10 x 10 grid. To show exactly 77%, you would shade 77 out of the 100 boxes that would be created by the grid. This will be the most basic way to model what exactly 77% is representing. To make it more realistic, you may want to space out the 77 boxes.
Answer:
D. 
Step-by-step explanation:
Let B represent the total bill in dollars.
We have been given that last night, 6 friends went out to dinner at a restaurant. They split the bill evenly.
We can find the amount paid by each friend for the dinner by dividing B by 6.
As we are told that each friend paid $14.75, so upon equating this amount to our equation we will get,
Therefore, the equation can be used to find the total amount of bill in dollars and option D is the correct choice.
