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.
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

Two questions can you please answer correctly.
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.

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.
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

What is the value of _a_ in the equation below?
2a + 3 = 4a + 5
Step-by-step explanation:
hope it is helpful to you
Step-by-step
Simplifying 2a + 3 = 4a + 5
Reorder the terms: 3 + 2a = 4a + 5
Reorder the terms: 3 + 2a = 5 + 4a
Solving 3 + 2a = 5 + 4a
Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right.
Add '-4a' to each side of the equation. 3 + 2a + -4a = 5 + 4a + -4a
Combine like terms: 2a + -4a = -2a 3 + -2a = 5 + 4a + -4a Combine like terms: 4a + -4a = 0 3 + -2a = 5 + 0 3 + -2a = 5 Add '-3' to each side of the equation. 3 + -3 + -2a = 5 + -3 Combine like terms: 3 + -3 = 0 0 + -2a = 5 + -3 -2a = 5 + -3 Combine like terms: 5 + -3 = 2 -2a = 2 Divide each side by '-2'. a = -1 Simplifying a = -1
