The ratio of green beads to yellow beads in a bracelet is three to four. The total number of beads is 14. How many green beads a
Alja [10]

Answer:

There are 6 green beads there.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of green beads

y is the number of yellow beads

The ratio of green beads to yellow beads in a bracelet is three to four.

This means that

\frac{x}{y} = \frac{3}{4}

So

3y = 4x

y = \frac{4x}{3}

The total number of beads is 14.

This means that x + y = 14

How many green beads are there ?

This is x.

x + y = 14

However

y = \frac{4x}{3}

So

x + \frac{4x}{3} = 14

Using multiplying by the gcm(3)

3x + 4x = 42

7x = 42

x = 6

There are 6 green beads there.

Answer:

46.2^o

Step-by-step explanation:

<u><em>The correct question is</em></u>

If b = 9 and c = 13, what is the measure of ∠A? (round to the nearest tenth of a degree)

The picture in the attached figure

we know that

In the right triangle ABC

cos(A)=\frac{b}{c} ---> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

cos(A)=\frac{9}{13}

using a calculator

A=cos^{-1}(\frac{9}{13})=46.2^o
