Answer:
(x,y)=(3/2, -1/2)
Step-by-step explanation:
2x+4y=1 /*3
3x-5y=7 /*(-2)
6x+12y=3
-6x+10y=-14
...........................
/ 22y=-11
y= -11/22
y= -1/2
2x+4*(-1/2)=1
2x-2=1
+2 +2
2x=3
x=3/2
so the solutionis (x,y)=(3/2, -1/2)
Answer:
3/4*5/11=15/44
Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
Diameter of pool A = 2 * radius = 2 * 22
= 44 feet
= 44 * 0.305 = 13.42 meters.
The diameter of Pool B ( 13. 6 m) is greater than the diameter of Pool A.
The circumference of Pool A is 13.42 * pi = 42.16 m and that of B is 42.73 m, so that the circumference of Pool B is greater than that of Pool A by
0.57 m.
Answer: 31.25 cm^2
Step by Step Explination: I just went onto Google and typed in "surface area of a pyramid formula," and then entered the given values, and the given length and width are equal.
Hope this helps!
Area = (1/2) * 4 * 5 = 10 cm²
