Answer:

x = 2

The smaller angle = 20

The larger angle = 70

Step-by-step explanation:

1/4 of a circle is  90 degrees

90 = 10x+ 20x+30

Combine like terms

90 = 30x+30

Subtract 30 from each side

90-30 = 30x+30-30

60 = 30x

Divide each side by 30

60/30 = 30x/30

2= x

10x = 10*2 = 20

20x+30 = 20*2 + 30 = 30+30 = 70

The number of employees for a certain company has been decreasing each year by 7​%. If the company currently has 790 employees a
Vikki [24]

Answer:

The number of employees in 8 years  is  442

Step-by-step explanation:

Given:

Decreasing rate = 7%

Current number of employees = 790

To Find:

The number of employees after 8 years is this same rate continues =?

Solution:

Let the number of employees after 8 years be x

The current number of employees is:

790(1-0.07)^0=790---------------------------------(1)

since the decrase rate is 7% we use 0.07

So after 8 years , eq (1) can be rewritten as

790(1-0.07)^8= x

790(0.93)^8= x

790 \times 0.5595= x

x= 442.005

x= 442 (approx)

Which box-and-whisker plot represents the data set?<br><br> 11, 6, 19, 14, 21, 7, 13, 15, 15
Katena32 [7]
The box and whisker plot is attached.

We first order the data from least to greatest:
6, 7, 11, 13, 14, 15, 15, 19, 21

The median is the middle value, or 14.
The lower quartile is the median of the lower half (split by the median).  This is between 7 and 11: (7+11)/2 = 18/2 = 9
The upper quartile is the median of the upper half (split by the median).  This is between 15 and 19:  (15+19)/2 = 34/2 = 17
The highest value is 21.
The lowest value is 6.

We draw the middle line of the box at 14, the median.  We draw the left side of the box at the lower quartile, 9.  We draw the right side of the box at the upper quartile, 17.  From the right side of the box, we draw a whisker to the highest value, 21. From the left side of the box, we draw a whisker to the lowest value, 6.

In triangle ABC, the side lengths are AB = 13, AC = 21, and BC = x. Write a compound inequality that represents the range of pos
N76 [4]

There is only 1 solution for the length of BC.

We can calculate it using Pythagorean theorem.

We can conclude that triangle's hypotenuse is AC.

AC^2=AB^2+BC^2

If that is the case we are looking for a side BC.

BC=\sqrt{AC^2-AB^2}

Now put in the data.

BC=\sqrt{21^2-13^2}=\sqrt{272}=\sqrt{272}\approx\boxed{16.49}

Hope this helps.
