Answer:
7
Step-by-step explanation:
56/2=28 (since the formula is w x l x 2)
28/4=7
Width is 7 inches and length is 21 inches.
7 + 21 = 28 x 2 = 56
Answer:
A
Step-by-step explanation:
The cosine of a right triangle is the adjacent over the hypotenuse. If the cosine is -3/5 then it must be a right triangle with sides 3, 4, & 5 since this is a Pythagorean triple. This means the sin will be -4/5. We know its negative because the tangent is positive so this is the 3rd quadrant where both Sine and Cosine are negative.
Answer:
The answer is D.
Step-by-step explanation:
Well, all the equations are the same except for the symbol so you don't need to figure out the equation of the line.
Anyways, note that the line is dotted, which means it cannot be A nor B since they have an "equal to."
Also, note that the shaded region is above the graph. Since it is above, it means that y is greater than whatever x is.
Thus, the answer is D.
(6+6+6)(36+1) = (18)(37) = 666. ... If you don't want an answer posted, there's a simple solution ... don't post the question ! And if it still mysterously somehow appears, then for heaven's sake, don't offer points as a reward for an answer. ... Finally ... devil's numbers belong in the Old Wives' Hooey category, not in the Mathematics one. They're not real.
X-intercept mean y=0
2/5x+1/10(0)=2
2/5x=2
X= 5
X-intercept = (5,0)
Y-intercept means x= 0
2/5(0)+1/10y=2
1/10y=2
y=20
Y-intercept = (0,20)
