$9.60 because 4 times 3 is 12 so that’s 12 pens right there in 3 groups of 4 which 2.25 is the cost for one romp so 2.25 times 3 is 6.75 and u need 15 so 15-12 is 3 so u need 3 more and one pen cost 0.95 times 3 is 2.85 so that plus 6.75 is your answer for your profit of $9.60
The Pythagorean Theorem is a^2 + b^2 = c^2
It’s usually used on triangles when two sides are given but one isn’t. C represents the hypotenuse while A and B are interchangeable. So solving for the hypotenuse would look like √a^2+ b^2= c but solving for a or be would look like √c^2-b^2 = a and √c^2-a^2= b.
So number wise √5^2+12^2 = 13
7n-2n+3p+2p
5n+5p (combine like terms)
the answer is 5n+5p
Given that the slide is 4.3 m long and makes an angle of 31°, then to get how high the slide is above the ground we use trigonometry formula.
sin θ=opposite/hypotenuse
opposite=x=how high the slide is above the ground
hypotenuse=length of the slide=4.3 m
θ=31°
plugging the values in the formula and solving for x we obtain
sin 31=x/4.3
x=4.3×tan 31
x=4.3(0.6009)
x=2.58387
x~2.6 m
Hence we conclude that the top of the slide is approximately 2.6 m from the ground
