Shaila bought 30 t-shirts at a clothing store. 20% of the t-shirts were blue and ½ of the shirts were black. How many of the t-s
abruzzese [7]

Answer:

9 shirts

Step-by-step explanation:

20% of the shirts were blue

20% of 30 is 6

6 shirts were blue

1/2 of the shirts were black

1/2 = 50%

50% of 30 is 15

15 shirts are black

15 + 6 = 21

30 - 21 = 9

(or you could add the percentages to get 70%, and get 30%. 30% of 30 is 9.)

Hope this helps!

Please!! What is the slope of each line? <br><br> Are they the same or different?
Korvikt [17]

Given:

The graph of two lines.

To find:

The slope of each line and check whether they are same or different.

Solution:

If a line passes through two points, then the slope of a line is:

m=\dfrac{y_2-y_1}{x_2-x_1}

From the graph 1, it is clear that the line passes through the points (2,175) and (3,165). So, the slope of first line is:

m_1=\dfrac{175-165}{3-2}

m_1=\dfrac{10}{1}

m_1=10

The slope of first line is 10.

From the graph 2, it is clear that the line passes through the points (1,175) and (2,165). So, the slope of first line is:

m_2=\dfrac{175-165}{2-1}

m_2=\dfrac{10}{1}

m_2=10

The slope of second line is 10.

m_1=m_2

Therefore, the slopes of both lines are same, i.e. 10.

Answer:

x = 56.31%

Step-by-step explanation:

to find x, use tan^{-1}

tan^{-1} x = \frac{opposite}{adjacent}

tan^{-1} x = \frac{15}{10}

tan^{-1} x = 1.5

x = 56.3099

56.3099 = 56.31
