Answer:
hindi sila pareho pero huwang mong sagutin kung hindi sila same terms dapat pareho sila
Step-by-step explanation:
dapat ganto 2x-2x= -x²
"27 percent" means 0.27
"of" means "times"
"27 percent of 300" means (0.27 x 300) = 81 .
At the beginning, you asked what percent this is.
81 is 8,100 percent .
Answer:
x = 2√7, y = √21
Step-by-step explanation:
The textbook has right angles, so we can use Pythagorean theorem to find the missing lengths.
For the triangle on top of the textbook:
c² = a² + b²
8² = 6² + x²
64 = 36 + x²
28 = x²
x = √28
x = 2√7
For the triangle on the side of the textbook:
c² = a² + b²
7² = x² + y²
49 = 28 + y²
21 = y²
y = √21
a
x 0.5x + 10 y
0 0.5(0) +10 = 10 (0,10) the y intercept
1 0.5(1) + 10 = 10.5 (1, 10.5)
4 0.5(4) + 10 = 12 (4, 12)
5 0.5(5) + 10 = 12.5 (5, 12.5)
6 0.5(6) + 10 = 13 (6, 13)
b
see attached graph
c
Since they add ten for each call before they multiple miles it is not proportional.
d.
No because the graph shows negative numbers and presumably the company can't charge you if they don't drive there.
Answer:
Using the formula to calculate the area of a square, the side of the patio can be 11.4 ft.
Step-by-step explanation:
Square patio
Area: A=130 square feet= 130 ft^2
Side of the square: s=?
The formula to calculate the area of a square is:
A = s^2
Replacing A by 130 ft^2
130 ft^2 = s^2
Solving for s: Square root both sides of the equation above:
sqrt(130 ft^2) = sqrt(s^2)
11.40175425 ft = s
s = 11.40175425
Rounding to the nearest tenth:
s = 11.4 ft
