Let the amount that the boys sold be x, the amount that girls sold will be 3x. The total will be given by:
x+3x=180
4x=180
solving for x we get:
x=180/4
x=45
Thus, boys sold $45, the girls provided 45*3=$135
Answer:
(0,0), (0,1), (1,2), (1,3)
Step-by-step explanation:
To determine what makes ordered pairs a function, we have to make sure each input (x) goes to exactly one output (y).
The reason this is the answer is that each input doesn't have exactly one output. (0 goes to 0 and 1. 1 goes to 2 and 3).
When you multiply radical expressions you multiply the numbers under the radical symbols.<span><span>3–√</span>×<span>7–√</span>=<span>21<span>−−</span>√</span></span>
When you add radical expression you CANNOT add the numbers under the radical symbols.
<span><span>3–√</span>+<span>7–√</span>≠<span>10<span>−−</span><span>√</span></span></span>
10^7 = 10,000,000
9.7x10^7 = 9.7x10,000,000
9.7x10,000,000 = 97,000,000
8.7x10^5 = 870,000
870,000x25 = 21,750,000
1. 21,750,000 new people are added after 25 years
2. The total population after 25 years is 118,750,000
The sum of given series is 44
<em><u>Solution:</u></em>
Given that we have to find the sum of the series
<em><u>Given series is:</u></em>
Substitute k = 1 to k = 4 to find the sum of the series
When k = 1:
When k = 2:
When k = 3:
When k = 4:
<em><u>Therefore, the sum of series is given as:</u></em>
Thus the sum of series is 44
