We should use lb to convert weight to kg

let unknown lb be = X
14 lb = 1 stone
X lb = 9 stone
Cross multiply : X × 1 = 9 × 14
X = 126 / 1 = 126 lb

9 stone = 126 lb
let unknown value of kg be = Y
2.2 lb = 1kg
126 lb = Y kg
Cross multiply : 2.2 × Y = 126 × 1
Y = 126 / 2.2 = 57.3 kg

So 9 stone = 126 lb = 57.3 kg

HOPE IT HELPED !!

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°.

garri49 [273]

Answer:

AB=15 BD=18

Step-by-step explanation:

AB is 15 because AB=AC and AC is 15

BD:

Using the Pythagorean Theorem

10²+15²=√325

√325=18

10 is from AB-CD

15 is the height which is AC

I need help with geometry!

ss7ja [257]

Step-by-step explanation:

If m is parallel to n and one of its angle is 25

Therefore, the vertically opposite angle to angle of 25 is also equal to 25

Now, we have to find x

Therefore, x=180-25 ( interer angles on the same side of the transversal so addition of both angles is 180)

Therefore, x =155

The length of each side of a square is 3 in. more than the length of each side of a smaller square. The sum of the areas of the

Taya2010 [7]

Answer:

$L_1 = 4$

And $L_2 = 3 +4 = 7$

Step-by-step explanation:

For this case we assume that for the first square we have the following dimensions:

$A_1 = L^2_1$

And we know that:

$L_2 = 3 + L_1$

And the area for the second square would be:

$A_2 = L^2_2 = (3+L_1)^2 = 9 + 6L_1 + L^2_1$

And we know that the sum of areas is 65 so then we have this:

$A_1 + A_2 = 65$

And replacing we got:

$L^2_1 + 9 + 6L_1 + L^2_1 = 65$

$2L^2_1 +6L_1 - 56=0$

We can divide the last expression by 2 and we got:

$L^2_1 + 3L_1 -28=0$

And we can factorize the last expression like this:

$(L_1 + 7) (L_1 -4) =0$

And we have two solutions for $L_1$ and we got:

$L_1 = 4, L_1 = -7$

Since the length can't be negative we have this:

$L_1 = 4$

And $L_2 = 3 +4 = 7$
