4 (0.5f - 0.25) = 6 + f
2.0f - 1.0 = 6.0 + f
1.00f = 6.0 + f
f = -5.0
hope this is right,

Understanding perpendicular and parallel lines are extremely important, especially in the engineering field when building infrastructures or houses because they need to calculate how they will keep a building stable. For example, bridges we see have a lot of perpendicular and parallel lines, that's because without those the bridge can't hold itself up, it needs support from the metals that are parallel and perpendicular.
hope this helps!!
(a) There are 1/4 cups of flour per serving
<u>Work:</u> 1.5/6=1/4
(b) There are aprox. .18 cups of sugar per serving.
<u>Work:</u> 9/12+4/12=13/12 n then divide 13/12 by 6
(c) You need 2 1/4 cups of flour to make 9 servings
<u>Work:</u> 1.5/2=.75 1.5+.75=2.25=2 1/4 cups
(d) Someone would need to know the amount of sugar per serving to make the recipe accurate.
<em>Question 2</em>
(a) You're account is at $10 dollars
<u>Work:</u> $5x5 (days)=$25. add 25 to -15 and you have $10 dollars in you're account.
(b) 5 days.
<u>Work:</u> 10/2=5 10-10=$0
Answer:
sin^2(θ)+cos^2(θ)=1
Step-by-step explanation:
We know that the statement above is true because of the Pythagorean identity theorem, which states the aforementioned equation. If you solve the equation for 1 you get the same equation.
To do this first multiply both sides by cos(θ), this gives you (cos^2θ)/1+sinθ = 1-sinθ
Then, multiply both sides by sinθ. This equals cos^θ=1-sin^2θ.
Finally, add sin^2θ to both sides. This equals the final answer of cos^2θ+sin^2θ=1. Which is true.
