#1) A
#2) E
#3) C
#4) 0.5840
#5) 0.6945
#6) 0.4911
#7) D
#8) G
#9) 0.4375
#10) 0.5203

The formula we use for this is
$v_w=f\lambda$ ,
where $v_w$ is the speed of sound, f is the frequency (or pitch) of the note, and λ is the wavelength.

#1) 0.77955f = 343

Divide both sides by 0.77955:
0.77955f/0.77955 = 343/0.77955
f = 439.997 ≈ 440. This is the pitch for A.

#2) 0.52028f = 343
Divide both sides by 0.52028, and we get f = 659.260. This is the pitch for E.

#3) 0.65552f = 343
Divide both sides by 0.65552, and we get f = 523.25. This is the pitch for C.

#4) 587.33λ = 343
Divide both sides by 587.33 and we get λ = 0.583999 ≈ 0.5840.

#5) 493.88λ = 343
Divide both sides by 493.88, and we get λ = 0.6945.

#6) 698.46λ = 343
Divide both sides by 698.46 and we get λ = 0.49108 ≈ 0.4911.

#7) 0.5840f = 343
Divide both sides by 0.5840 and we get f = 587.3288 ≈ 587.33. This is the pitch for D.

#8) 0.4375f = 343
Divide both sides by 0.4375 and we get f = 784. This is the pitch for G.

#9) 783.99λ = 343
Divide both sides by 783.99 and we get λ = 0.4375.

#10) 659.26λ = 343
Divide both sides by 659.26 and we get λ = 0.52028 ≈ 0.5203.

Answer:

14. 2384 in²

15. 291.8 in²

Step-by-step explanation:

14. The total surface area consists of the area of two equal triangles and three rectangles.

The area of each triangle is $\frac{1}{2} bh$ , which is $\frac{1}{2}(24)(14)=168 in²$ . The area of both triangles combined is 336 in².

The area of each of the slanted rectangles is base x height, which is 25x32=800 in². The area of both rectangles combined is 1600 in².

The area of the base rectangle is 14x32=448 in².

Therefore, to find the total surface area, you add the area of each side together: 336+1600+448=2384 in².

15. The equation for the surface area of a cylinder is $2\pi r^{2} +2\pi rh$ .

The radius (r) is 4.6 in and the height (h) is 9.1 in.

Therefore, the surface area is:

$2\pi (4.6)+2\pi (4.6)(9.1)=28.888+262.88=291.8\\$ in²

Answer:

I will make <u>$ 13.20</u> per hour

Step-by-step explanation:

Given:

Employee gets money for Working from 2.00 PM to 6.00 PM = $\$ 12$ per hour

Employee gets money for working from 6.00 PM to 12.00 AM will get additional 10 $\%$ = $\frac{10}{100}\times12= \$ 1.2$ per hour

Employee gets money for working from 12.00 AM to 01.00 AM will get additional 15 $\%$ = $\frac{15}{100}\times12= \$ 1.8$ per hour

Solution:

Employee works from 2.00 PM to 12.00 AM= Employee gets money for Working from 2.00 PM to 6.00 PM + 10 $\%$ extra wage = $\$ 12 + \$ 1.2 = \$ 13.2$

A rectangle is drawn so that the width is 3 feet shorter than the length. the area of the rectangle is 40 square feet. find the

Tpy6a [65]

Draw a rectangle and label the right side as L-3 and the bottom side as L.

Area is L x W...in this case L(L-3) = 40.....we get

L^2 - 3L = 40 (subtract 40 from each side we get...)
L^2 - 3L - 40 = 0 (factor this out to get the L and W)
