Answer:
a = 10.9
b = 10.4
Step-by-step explanation:
part a: use sine
⇒ sine = [tex]\frac{opposite}{hypotenuse}[/tex]
⇒ sine 23 = [tex]\frac{y}{28}[/tex]
(sine 23 = 0.39)
⇒ 0.39 = [tex]\frac{y}{28}[/tex]
multiply each side by 28
⇒ 0.39 x 28 = [tex]\frac{y}{28}[/tex] x 28
⇒ 10.9
part b: use cosine
⇒ cos = [tex]\frac{adjacent}{hypotenuse}[/tex]
⇒ cos 29 = [tex]\frac{y}{12}[/tex]
(cos 29 = 0.87)
⇒ 0.87 = [tex]\frac{y}{12}[/tex]
multiply 12 on both sides
⇒ 0.87 x 12 = [tex]\frac{y}{12}[/tex] x 12
⇒ 10.4

x = 10-13 = -3
8= y+10/2
16= y+10
y = 16-10 = 6

Step-by-step explanation:
Lets convert everything into pure feet.
10ft 5in = 10 and 5/12 feet = 125/12 feet
14ft 2in = 14 and 1/6 feet = 85/6
Now lets calculate area:
1/2 * 125/12 * 85/6 = 125*85 / 144 = 73 and 113/144

PLSSS HELP MEEE DUDE HELP MEEEEEE Marshall High School’s community service club will be selling baked goods as a fundraiser. The club members plan on making cupcakes and cookies. There will be 5 cookies made for every 2 cupcakes made. The club members plan on making 280 total baked goods.
Plot the point on the coordinate plane below that represents the total number of cupcakes and the total number of cookies that the community service club members plan on making for the fundraiser.
To plot the point, click the pencil tool and select the thickest brush size.
Answers
Answer:
See Explanation
Step-by-step explanation:
Let the number of cookies be x and the number of cupcakes be y.
If the total is 280, then
[tex]5x + 2y = 280[/tex]
Subtract 5x from both sides
[tex]5x - 5x + 2y = 280 - 5x[/tex]
[tex]2y = 280 - 5x[/tex]
Make y the subject
[tex]y = 140 - \frac{5}{2}x[/tex]
See attachment for graph
Any of the following equation can be plotted on the graph (they literally represent the same thing)
[tex]5x + 2y = 280[/tex]
[tex]2y = 280 - 5x[/tex]
[tex]y = 140 - \frac{5}{2}x[/tex]

-89442719.1
Step-by-step explanation:
-12 × 5.47722558 =-657267069
3×2.44948974 = 7.34846923
657267069/7.34846923= -89442719.1
the square root of 30 is 5.47722558 which is multiplied by 12 to make -657267069
you the find the square root of 6 which is 2.44948974 and multiply it with 3.
after all, you divide -657267069 by 2.44948974 which is -89442719.1

The "key" to this is to recognize that the two lines have to be the same length, they put the drawing on it's side to make it harder to see that. :/ But another way to see this is that it's an isosceles triangle and you know the two legs that they are asking us about have to be the same length, knowing that.. we can set the two expression equal to each other
3x - 10 = 2x
now solve for x
3x - 10 -2x = 2x - 2x ( subtracting 2x from both sides )
3x - 2x - 10 = 0
x - 10 = 0
x - 10 + 10 = 0 + 10
x = 10 ( yay)
