Answer:
66 inches
Step-by-step explanation:
1. Yards to Feet:
1 yard= 3 feet
(6 yards)(3)= 18
6 yards = 18 feet
2. Number of Groups:
30 students/6 students per group= 5 groups
3. Total String Needed:
(5 groups)x(2.5 feet string)= 12.5 feet total string
4. Remaining String:
18 feet-12.5 feet= 5.5 feet
5. Feet to Inches:
1 foot= 12 inches
(5.5 feet)(12)= 66 inches
66 inches of string will remain

A positive integer squared plus 5 times its consecutive integer is equal to 11. Find the integers.
Answer:
The integer is 1
Step-by-step explanation:
Required
Translate and solve
Let the positive integer be x.
So, we have;
The square of the integer is: x^2
Plus 5 times its consecutive integer is: x^2 + 5(x + 1)
Equals 11 is: x^2 + 5(x + 1) = 11
So, we have:
[tex]x^2 + 5(x + 1) = 11[/tex]
Open bracket
[tex]x^2 + 5x + 5= 11[/tex]
Subtract 11 from both sides
[tex]x^2 + 5x -6= 0[/tex]
Expand
[tex]x^2 + 6x - x-6= 0[/tex]
Factorize:
[tex]x(x + 6) - 1(x+6)= 0[/tex]
Factor out x + 6
[tex](x - 1) (x+6)= 0[/tex]
Split
[tex]x - 1 = 0\ or\ x + 6 = 0[/tex]
Solve for x in both cases
[tex]x = 1\ or\ x = -6[/tex]
Since the number is positive, then [tex]x = 1[/tex]

Step-by-step explanation:
Without using a calculator, match each expression to the correct point.
Answer:
The locations of each irrational number are the following:
[tex]\sqrt{16}[/tex] - Point [tex]a[/tex]
[tex]\sqrt{27}[/tex] - Point [tex]b[/tex]
[tex]\sqrt{32}[/tex] - Point [tex]c[/tex]
Step-by-step explanation:
[tex]\sqrt{16}[/tex] is an irrational number that is also rational, since [tex]4^{2} = 16[/tex]. Then, [tex]\sqrt{16}[/tex] must be point [tex]a[/tex].
Both [tex]\sqrt{27}[/tex] and [tex]\sqrt{32}[/tex] are greater than [tex]\sqrt{25} = 5[/tex] and less than [tex]\sqrt{36} = 6[/tex]. Then, both are between 5 and 6. Since [tex]\sqrt{27} < \sqrt{32}[/tex], [tex]\sqrt{27}[/tex] must be point [tex]b[/tex] and [tex]\sqrt{32}[/tex] must be point [tex]c[/tex].

A large pizza has a radius of 7 in. The pizza is cut into 8 slices of equal size. What is the area of 1 slice, rounded to the nearest whole number? Use 3.14 for π.
Answer:
The area of 1 slice is of 19 square inches.
Step-by-step explanation:
Area of a circle:
The area of a circle of radius r is given by:
[tex]A = \pi r^2[/tex]
A large pizza has a radius of 7 in.
So its area of the pizza, in square inches, is of:
[tex]A = \pi(7)^2 = 49\pi = 49*3.14 = 153.86[/tex]
The pizza is cut into 8 slices of equal size. What is the area of 1 slice, rounded to the nearest whole number?
Area of the pizza divided by 8. So
153.86/8 = 19.2
Rounding to the nearest whole number, the area of 1 slice is of 19 square inches.

Diego is at the batting cage where they are currently offering batting cage customers their choice of The Slow
Ball Challenge or The Fast Ball Challenge.
The Slow Ball Challenge: There will be 10 pitches, each at 60 mph. Diego estimates that he will hit each
individual pitch 95% of the time. If Diego can hit all 10 pitches, he will win a total of $25; otherwise he will lose
$5.
The Fast Ball Challenge: There will be 3 pitches, each at 90 mph. Diego estimates that he will hit each
individual pitch 60% of the time. If Diego can hit all 3 pitches, he will win a total of $60; otherwise he will lose
$10.
What are Diego's expected winnings from playing The Slow Ball Challenge? Round your answer to the nearest

The batting cage is allowing customers to participate in their choice of either The Slow Ball Challenge or The Fast
Ball Challenge a total of 10 times.
If Diego wants to maximize his expected winnings, what should he do?
Answer:
The expected winnings from The Slow Ball Challenge rounded to the nearest dollar are $13
The expected winnings from The Fast Ball Challenge rounded to the nearest dollar are $5
Since The Slow Ball Challenge has higher expected winnings, Diego should play The Slow Ball Challenge all 10 times.

Roddy adjusts his simulation, making it easier and easier to win. Eventually, he finds that if the random numbers are between 1 and 4, and the contest only runs for 4 days, about 39 out of 10,000 people are likely to win (by getting 4,4,4,4).
He runs this simulation repeatedly to be sure and then sets aside 39 concert tickets, plus a few more to be safe.
When the contest is launched into the real world, though, what factors might affect the actual number of winners? Select all that apply.
The random chance of the number generator
People who get a 1 and then stop playing the game
The number of people who participate in the game
The results of his simulated trials
People who get a few 4s and then stop playing the game

Sam and you are going to paint your room together.
Sam takes 10 minutes to paint 25 square feet.
It takes you 5 minutes to paint 25 square feet.
Sam says, "If we paint together, then it will take 15 minutes for us to cover
feet."
TI
of
Give an explanation to convince Sam that she is incorrect.
.
Answer:
Sam is incorrect because you would not add the two times together. Hence there being 2 people working it would take you guys less time. You would actually subtract the times to get 5 minutes
Step-by-step explanation:
Answer:
Sam 's thinking is incorrect.
Step-by-step explanation:
Because If Sam takes 10 minutes to paint 25 square feet, then 5 minutes will be paint 12.5 sf... So if 15 minutes will paint 37.5 square feet. (by Sam)
---For me: if 5 mutes to paint 25 square feet.--->10 minutes will be 50 sf---> then 15 minutes will paint 75 square feet...
So If Same and I paint together will be 12.5 + 75 = 112.5 square feet
---Not 50 square feet...
What Sam says is incorrect....He can't add times together., that' s wrong.
Point Z is a centroid of the triangle VWY. If VZ = 42 cm, what is VX?

What is 42 + 21 ?
There you go, you have your answer!
VX = 63cm
Triangle is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
If Z is the centroid of the triangle VWY
VZ = ZX
VX = VZ + ZX
The value of VX is 84 cm.
Option D is the correct answer.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Point Z is a centroid of the triangle VWY.
VZ = 42 cm
Now,
Centroid means,
VZ = 42 cm
VZ = ZX
VX = VZ + ZX
VX = 42 + 42 = 84 cm
Thus,
The value of VX is 84 cm.
Option D is the correct answer.

Answer: (The first number are the years and the second are the amount of Komodo's) (0, 0) (1, 4) (2, 20) (3, 100) (4, 500) (5, 2,500)
Step-by-step explanation:
If there are 4 Komodo's in the first year because that's when they moved in, then there would be zero in the 0 year.
If they keep multiplying their population by 5 each year then for every year, you would multiply the existing population of that year by 5
Starting at year 1 which is (1, 4) multiply that by 5 to get 20 and so on to get the function.
