Tpy6a [65]

Answer:

SA = 2520 ft^2

Step-by-step explanation:

a = 21ft

b = 29ft

c = 20ft

h = 30ft

SA = 2 $A_{B}$ + (a+b+c)h

$A_{B}$ = s(s﹣a)(s﹣b)(s﹣c)

s = $\frac{a + b + c}{2}$

SA= ah + bh + ch + $\frac{1}{2}$ $\sqrt{-a^4 + 2(ab)^2 + 2(ac)^2 - b^4 + 2(bc)^2 - c4}$

SA= (21 * 30) + (29 * 30) + (20 * 30) +

$\frac{1}{2}$ $\sqrt{-(21)^4 + 2(21 * 29)^2 + 2(21 * 20)^2 - (29)^4 + 2(29 * 20)^2 - (20)^4}$

SA = 2520 ft^2

Eduardo and Paul are leaving the same airport in Florida. Eduardo’s flight to Jamaica is 273 miles long. Paul's flight to Hondur

k0ka [10]

Answer:

B. 41.8° is the correct answer

Step-by-step explanation:

We are given that,

Length of Eduardo's flight path = 273 miles

Length of Paul's flight path = 357 miles

Distance between their destinations = 238 miles.

Now, using the law of cosines, we get,

$238^2=273^2+357^2-2\times 273\times 357\times \cos \theta$

i.e. $56644=74529+127449-194922\times \cos \theta$

i.e. $56644=201978-194922\times \cos \theta$

i.e. $194922\times \cos \theta=145334$

i.e. $\cos \theta=0.7456$

i.e. $\theta=\arccos 0.7456$

i.e. θ = 41.8°

Hence, the angle between their flight paths is 41.8°.

A recipe uses 2/3 cup of flour and 5/8 cup of blueberries. Is there more flour or more blueberries in the recipe?

gladu [14]

Hey there!
In order to compare these fractions, we can give them a common denominator.
Our least common multiple of 3 and 8 is 24. We multiply 2/3 by 8/8 and 5/8 by 3/3 to get
16/24 and 15/24
Therefore, 2/3 is bigger.
Hope this helps!

Danielle says the answer is "A". Is she correct? If she is,why? And if she isn't,what is the correct answer?

Naddik [55]

Answer:

She is incorrect. The correct answer is 285.74

Step-by-step explanation:

A= (pi)r^2

Training wheel: A= (3.14)(3)^2=28.26in^2

Wheel: A= (3.14)(10)^2= 314in^2

314-28.26=285.74in^2

In Triagle ABC , DE is parallel to BC . The measure of < A is 60 degrees and the measure of < DEC is 125 degrees . What is

xxTIMURxx [149]

Step-by-step explanation:

Since DE is parallel to BC, the mL C = 180° -125° = 55°.

so, the measure of L B = 180° - L A - L C =

180° - 60° - 55 = 65°
