To answer this I believe you have to use cross-multiplication. If she scores 4 goals in 6 games, how many would she score in 21 games? We can set up the equation 4/6 = x/21. This implies that both sides are equal, hence the same rate of scoring. Now all that's left is to solve for x. You have to cross-multiply, so 4 times 21 = 84, and 6 times x = 6x. Now the equation looks like 84 = 6x. Now divide by 6 on both sides to solve for x. 84 divided by 6 = 14. So Latasha scored 14 goals in the season.

Step-by-step explanation:

First question:

You are given a side, a, and its opposite angle, A. You are also given side b. Use that in the law of sines and solve for the other angle, B.

$\dfrac{a}{\sin A} = \dfrac{b}{\sin B}$

$\dfrac{10}{\sin 30^\circ} = \dfrac{40}{\sin B}$

$\dfrac{1}{0.5} = \dfrac{4}{\sin B}$

$\sin B = 2$

The sine function can never equal 2, so there is no triangle in this case.

Answer: no triangle

Second question:

You are given a side, b, and its opposite angle, B. You are also given side c. Use that in the law of sines and solve for the other angle, C.

$\dfrac{b}{\sin B} = \dfrac{c}{\sin C}$

$\dfrac{10}{\sin 63^\circ} = \dfrac{}{\sin C}$

$\sin C = \dfrac{8.9\sin 63^\circ}{10}$

$C = \sin^{-1} \dfrac{8.9\sin 63^\circ}{10}$

$C \approx 52.5^\circ$

One triangle exists for sure. Now we see if there is a second one.

Now we look at the supplement of angle C.

m<C = 52.5°

supplement of angle C: m<C' = 180° - 52.5° = 127.5°

We add the measures of angles B and the supplement of angle C:

m<B + m<C' = 63° + 127.5° = 190.5°

Since the sum of the measures of these two angles is already more than 180°, the supplement of angle C cannot be an angle of the triangle.

Answer: one triangle

A car is driving 90 kilometers per hours how far in meters does it travel in 3 second

serious [3.7K]

Answer:

<u><em>I hope it will work</em></u>

Step-by-step explanation:

as given

speed = v = 90 km/hr convert to meter and sec we get

v =( 90 *1000 meter)/(3600 sec)

v=25 m /sec

as given t= 2 sec so

v=s/t

s= v*t

s=25*2

s=50 meter

if its help-full hit the stars and brain list it thank-you
