Answer:
0.70x+5x=20
Step-by-step explanation:
This is because we are not given the exact number for the equation, so we use x to represent the missing numbers.
Answer:
28 were senior citizens
A common denominator between 9 and 5 is 45.
<u>4 ·5 20</u> <u>2 ·9 18</u>
9 ·5 45 5 ·9 45
20/45 + 18/45 is 38/45
38/45=x/180
solve for x
<u>38 ·4= 152</u>
45 ·4= 180
152 out of the 180 visitors were NOT senior citizens.
180-152=28
28 visitors were senior citizens
Hope this helped :)
First you have to make the assumption that these are the only two outcomes. There is also the possibility of hitting the ball and getting out.
However, if we assume that these are the only two cases, we know that the probability is 58.3%. This is because it has been on base 7 times out of 12.
Answer:
<em>$</em><em>420</em>
Step-by-step explanation:
<em>Principal</em><em> </em><em>=</em><em> </em><em>$</em><em>7000</em>
<em>Rate</em><em> </em><em>=</em><em> </em><em>8</em><em>%</em>
<em>Time</em><em> </em><em>=</em><em> </em><em>9</em><em> </em><em>months</em>
<em>9</em><em> </em><em>months</em><em> </em><em>=</em><em> </em><em>3</em><em>/</em><em>4</em><em> </em><em>or</em><em> </em><em>0.75</em><em> </em><em>of</em><em> </em><em>a</em><em> </em><em>year</em>
<em>Simple</em><em> </em><em>Interest</em><em> </em><em>=</em><em> </em><em>Principal</em><em> </em><em>*</em><em> </em><em>Rate</em><em> </em><em>*</em><em> </em><em>Time</em><em> </em><em>÷</em><em> </em><em>100</em>
<em>=</em><em> </em><em>$</em><em>7000</em><em> </em><em>*</em><em> </em><em>8</em><em>%</em><em> </em><em>*</em><em> </em><em>0.75</em><em> </em><em>÷</em><em> </em><em>100</em>
<em>=</em><em> </em><em>$</em><em>420</em>
Yo sup??
We can solve this problem by applying trigonometric ratios.
sin27=DC/BD
BD=DC/sin27
=8.8
