Answer:
1. (29 + 19) ➗ 3
(48) ➗ 3
48➗ 3
There are 16 cards in each pile
Step-by-step explanation:
2. 14 3. 110 4. 71 5. 54 6. 16 7. 23
8. 75 9. 32 10. 22 11. 20 12. 48 13. 53
14. Spit 6 in half to get Melinda's length so the answer is 3
15. No the answer is not the same because you have to minus 18 to 8 (which is in the parenthesis) so the answer is 10. But the other way around you have to add 15 (which is in the parenthesis) plus 5.
I really hope I helped you
Answer:
the answer is 3.78
Step-by-step explanation:
Answer:
Answer is 71.95°
Step-by-step explanation:
Cosine formula is
a^2=b^2+c^2-2bc(cosA)
cos A =b^2+c^2-a^2/2bc
if a= 119,b=94,c=173
cos A=94^2+173^2-119^2/2(94*173)
=8836+29,929-14,161/2(16,262)
=38765-14,161/32,524
=24604/32,524
=0.7564
cos A=0.7564
cos^-1=40.85°.that's for angle A.
Using the same formula
B=31.1°
C=180-(40.85+31.1)
C=180-71.95
C=108.05
Since angle on a straight line is 180
therefore x is 71.95
Also the sum of angles A and B
Answer:
y = -x - 8
Step-by-step explanation:
Midpoint of the line:
x = (x1 + x2)/2 = (-8 + -4)/2 = -12/2 = -6
y = (y1 + y2)/2 = (-5 + 1)/2 = -4/2 = -2
so midpoint is (-6,-2)
Slope of the line: Slope m = (y2-y1)/(x2-x1)
m = (-1 - -5)/(-4 - -8) = (-1 + 5)/(-4 + 8) = 4/4 = 1
Perpendicular lines have slopes that are negative reciprocals of one another
so slope of the perpendicular line is -1/1 is -1
y = mx + b
y = -x + b
Using (-6,-2)
-2 = -(-6) + b
-2 = 6 + b
b = -8
so y = -x - 8
