You have to fill in 3 for x so it woul look like 3x3-3 and that would be 6.
Answer:
a= 168
p= 62
Step-by-step explanation:
25 24 and 7 are pythagorean triples. meaning the short side length is 7.
24*7 = 168
48+14=62
Answer:
33.89
Step-by-step explanation:
the side lengths are the distances between the corner points of the triangle.
P and Q have the same x value, and they therefore create a side parallel to the y-axis. and it is easy to find the length of this side : it is just the difference of the y values.
PQ = 6 - (-6) = 6 + 6 = 12
QR and RP are trickier.
we need Pythagoras to calculate the length of the direct connection between these points as the Hypotenuse of the right triangles with the differences in x and in y values as the other sides.
QR :
QR² = (-3 - 6)² + (-6 - -2)² = (-9)² + (-4)² = 81 + 16 = 97
QR = sqrt(97) ≈ 9.848857802
RP :
RP² = (6 - -3)² + (-2 - 6)² = 9² + (-8)² = 81 + 64 = 145
RP = sqrt(145) ≈ 12.04159458
the perimeter/circumference of the triangle is the sum of all 3 sides
= 12 + sqrt(97) + sqrt(145) ≈ 33.89
You can say : 15% ⇒ ? if 100% ⇒ 32.50 $
so next you can say : 15/100 = ?/32.50 ⇒ ? = (15/100) × 32.50 = 15 × 32.50 ÷ 100 = 4.875 ⇒ so the answer is 4.785 $ ;D i hope this will be helpful :))
Answer:
It is by definition. 210 means 21 tens or 21 * 10. 30 means 3 tens or 3*10.
Since there is a ten on the top and bottom of the divisor 210/30 is also the same thing as 21/3. All of which is 7 and all of which is true by definition.
