At this weekend’s football game, 20 out of the first 50 people who entered the field were not wearing hats. If this sample is representative of the 300 people attending the game, about how many of them will probably NOT be wearing hats? Show all work and justify your answer.
Answers
Answer:
180 People will wear Hats
Step-by-step explanation:
If there are 30 people that wear hats out of 50 we extrapolate that data meaning we just multiply both till we get the disired number of 300, so 50x6 = 300, so 30x6= 180

Im trying to do IXL and I dont understand the way my teacher teaches (ironic right?)
the points (-2,-10) and (8,r) fall on a line with a slope of 1/10. What is the value of r?
Answers
-10-r/-2-8= 1/10
-10-r/-10= 1/10
Multiply the denominator (-10) on both sides
-10-r= -1
Add -10 to both sides
-r= 9
r= -9

Valeria already has $65 dollars in her savings account. If she puts $5 per week in her account, write and solve an inequality to find out how many weeks she must save to have at least $200 in her account.
Answers
Answer:
65 + 5x ≥200
Step-by-step explanation:
Hi, to answer this question we have to write an inequality with the information given:
Janice's savings (65) plus the product of the amount she saves per week (5) and the number of weeks (x) must be higher or equal to $200.
Mathematically speaking:
65 + 5x ≥200
If we solve it for x:
5x ≥200-65
5x ≥135
x ≥ 135/5
x ≥ 27 weeks
Feel free to ask for more if needed or if you did not understand something.

Answer:
First question: D. 6.28 ft
Second question: C. Rectangle
Step-by-step explanation:
The circumference of the circle is 6.28 ft. The first thing you do to find the circumference for this circle is find what the radius is. Since the diameter is equal to 2 times radius, and the diameter is 2, we know that the radius is one. Now, we can find the circumference. To find it, the formula is 2 times π times radius. For this problem, we use π for 3.14 and the radius for 2. In this case, 2 times 3.14 times 1 is equal to 6.28. Therefore, the circumference of this circle is equal to 6.28.
