Percent error : (approximate value - exact value) / exact value.....x 100

percent error : (5.75 - 6.25) / 6.25......ignore any negative signs
0.5 / 6.25 = 0.08.....x 100 = 8% error <==

Answer:

1). a = 9.42 m

2). b = 6.37 m

3). c = 4.48 m

Step-by-step explanation:

In the figure attached,

By applying tangent rule in triangle ADE,

tan47 = \frac{h}{c}

c = \frac{h}{\text{tan}47}

c = \frac{4.8}{\text{tan}47}

c = 4.476

c ≈ 4.48 m

Now we apply the same rule in triangle ACE,

tan37° = \frac{h}{b}

b = \frac{h}{\text{tan}37}

b = \frac{4.8}{1.0724}

b = 6.37 m

Now apply the tangent in triangle ABE,

tan27° = \frac{h}{a}

a = \frac{h}{\text{tan}27}

a = \frac{4.8}{0.5095}

a = 9.42 m

Snow cone holders are sold in sleeves of 50. How much paper is needed for each sleeve if the cones have a slant height of 5 inch
Genrish500 [490]

Answer:

The correct answer is

Step-by-step explanation:

Snow cone holders are sold in sleeves of 50.

The cones have a slant height (l) of 5 inches and a radius (r) of 3 inches.

Surface area of each cone holder = π × r × l = π × 15 = 15π square inches.

Surface area of all 50 cones in the sleeve = 15π × 50 = 750π = 2357.143 square inches.

Thus 2357.143 square inches pf paper would be necessary for each sleeve each having 50 cone holders.

Towns X, Y, and Z are on the same straight road. Town Y is between Town X and Town Z. Town X is 57 miles from Town Z, and Town Y
Ber [7]
29 miles 
because town y is between town x and town z so you can take the distance between town x and town z and subtract the distance from town y to town z
