<h3>
Answer: 130</h3>
Explanation:
Let x be the unknown angle we want to find.
Let y be adjacent and supplementary to x. This means x+y = 180
Let z also be adjacent and supplementary to x. So x+z = 180 also
Subtracting the two equations leads to y-z = 0 and y = z. So effectively we've proven the vertical angle theorem.
Since the supplementary angles to x add to 100, we know that y+z = 100. Plug in y = z and solve for z
y+z = 100
z+z = 100
2z = 100
z = 100/2
z = 50
Therefore,
x+z = 180
x+50 = 180
x = 180-50
x = 130
It is 1/3, add up the total number of kids, which is 30, the number of kids 6-8 is 10. 10/30 is equivalent to 1/3
Answer:
2400 people
Step-by-step explanation:
Let x be the number of people who had a swimming pool in the population of 10,000,
Thus, the ratio of people who had swimming pool to the total population = 
Since, out of 250 people 60 had swimming pool,
So, the ratio of the people who had swimming pool to the total population = 
Hence, 2400 people in the city might one expect to have a swimming pool.
First option is correct.
The product of the given expression is -120. Option A is correct
<h3>Product of negative numbers.</h3>
Given the expression below as shown;
−5⋅(−3)⋅(−8)
Since the product of two negative number is equal to positive, then;
−5⋅(−3)⋅(−8) = -8(5*3)
Simplify the result to have:
-8 * 15
find the final product
-8 * 15 = -8(5+10)
-8 * 15 = -40 - 80
-8 * 15 = -120
Hence the product of the given expression is -120
