A soccer player has made 3 of her last 10 field goals, which is a field goal percentage of 30%. How many more consecutive field
Monica [59]

Answer:

4 consecutive goals

Step-by-step explanation:

If 3 of last 10 field goals = 30%

Which is equivalent to

(Number of goals scored / total games played) * 100%

(3 / 10) * 100% = 30%

Number of consecutive goals one has to score to raise field goal to 50% will be:

Let y = number of consecutive goals

[(3+y) / (10+y)] * 100% = 50%

[(3+y) / (10+y)] * 100/100 = 50/100

[(3+y) / (10+y)] * 1 = 0.5

(3+y) / (10+y) = 0.5

3+y = 0.5(10 + y)

3+y = 5 + 0.5y

y - 0.5y = 5 - 3

0.5y = 2

y = 2 / 0.5

y = 4

Therefore, number of consecutive goals needed to raise field goal to 50% = 4

Help the question is the picture
nikdorinn [45]

Answer:

a>-21(1/3)

Step-by-step explanation:

3/4a>-16

first thing is to divide both sides by 3/4 to isolate the variable.

Since it is not negative, the sign stays the same.  

-16/0.75=-21.3 repeating or just 1/3

How do I find the value of xfor the following triangles
Naddik [55]

Given at the figure 1

A right triangle of legs of 10 and 16

We need to find the angle x

The side of 16 represent the opposite side of the angle x

The side of 10 represents the adjacent side of the angle x

According to the known sides, we can find x using tan function :

So,

\begin{gathered} \tan x=\frac{opposite}{adjacent} \\  \\ \tan x=\frac{16}{10}=1.6 \\  \\ x=\tan ^{-1}1.6=57.995 \end{gathered}

Rounding to the nearest degree

So, the measure of angle x = 58
