Acandidate took a phone poll of 110 people. of the 110 people polled, 87 said they would vote for the other person. there are 9570 people in the district.
about how many people are going to vote for the other candidate?

a) 7400 b) 7569 c) 7069 d) 7900

B)7569

Step-by-step explanation:

Total number of people in the district is 9570. The candidate took a phone poll of 110 people. The proportion of the total number people in the district that participated in the phone poll is 9570/110 = 87

This means that the total number of people in the district is 87 times the number that participated in the phone poll

If out of 110 people polled, 87 said they would vote for the other person, the number of people that would vote for the other person will be 87×87 = 7569

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
