Step-by-step explanation:
Before we answer, the area of a Circle given it radius is
[tex]a = \pi r {}^{2} [/tex]
The area of a circle given it diameter is
[tex]a = \pi( \frac{d}{2} ) {}^{2} [/tex]
So let answers question 1-4.
1. The area is
[tex]1024\pi[/tex]
2. The area is
[tex]576\pi[/tex]
3.
[tex]1.225\pi[/tex]
4.
[tex]309.76\pi[/tex]
For the 5th problem, circumference is
[tex]\pi \times d[/tex]
where d is the diameter and
[tex]2\pi r[/tex]
where r is the radius.
A circumference of 100 m means the radius is 50 because
[tex]2\pi \times r = 100\pi[/tex]
[tex]r = 50[/tex]
So this means the area is
[tex]2500 {\pi}[/tex]

if x = 5, y = 6, and z= 2, is V x2 + y2 + z2 + 50
rational or irrational? Explain.
Answers
Answer:
irrational
Step-by-step explanation:
because
5² + 6² + 2² + 50 = 25+36+4+50 = 115
and 115 is not a squared integer or rational number, so that sqrt(115) is one of these numbers with infinite digits after the decimal point but without any repeating pattern.
and that is per definition irrational.

A lawn in the shape of a trapezoid has an area of 1,800 square meters. The length of one base is 50 meters, and the length of the other base is 40 meters. What is the width of the lawn?
Answers
1800= 1/2h(50+40)

19. The product of two numbers is 120 and the sum of their squares is 289. The sum of the number is (a) 20 (b) 23 (c) 169 (d) None of these
Answers
Answer:
B
Step-by-step explanation:
Let the two numbers be a and b.
The product of the two is 120 and their sum of their squares is 289. In other words:
[tex]\displaystyle ab = 120 \text{ and } a^2 + b^2 = 289[/tex]
And we want to find the sum of the two numbers.
We can use the perfect square trinomial. Recall that:
[tex]a^2 + 2ab + b^2 = (a+b)^2[/tex]
From the first equation, multiply by two:
[tex]2ab = 240[/tex]
Add the two equations together:
[tex](a^2+b^2)+(2ab) = (289)+(240)[/tex]
Simplify and rewrite:
[tex]a^2+2ab+b^2 = 529[/tex]
Factor using the perfect square trinomial pattern:
[tex](a+b)^2 = 529[/tex]
And take the square root of both sides:
[tex]\displaystyle a + b = \pm\sqrt{529} = \pm23[/tex]
Hence, the sum of the two numbers is 23 or -23.
In conclusion, our answer is B.

b is obvious since you can just plug In a point to solve

In the Tigers Football Club, there are 9 players to each coach, while in the Eagles Football Club, there are 17 players to every 2 coaches. If the total number of players and coaches in the two clubs is 232, how many players and coaches are in each club?
Answers
9514 1404 393
Answer:
Tigers: 8 coaches, 72 playersEagles: 16 coaches, 136 playersStep-by-step explanation:
We can define a "basic unit" of each team to be the minimum number of players and coaches that can have the given ratio. For the Tigers, that is 1 coach and 9 players, for a total of 10 team members. For the Eagles, that is 2 coaches and 17 players, for a total of 19 team members. If we have t basic units of Tigers and e basic units of Eagles, then we want ...
10t +19e = 232 . . . . . the total of players and coaches in the two clubs
We want t and e to be integers, so this is a Diophantine equation. It can be solved any of several ways, including use of the Extended Euclidean Algorithm. Here, we'll make some observations based on "number sense."
The value of e must be an even number between 0 and 232/19 = 12. The product of e and 19 must be a number that ends in 2, because 10t will end in 0, and the sum with 19e must end in 2.
The only multiple of 9 that ends in 2 is 9×8 = 72, so the value of e must be a positive number less than 12 that ends in 8. We must have e=8.
Then t=(232 -8×19)/10 = 8. This tells us there are 8 "basic units" of each team.
The Tigers have 8 coaches and 72 players.
The Eagles have 16 coaches and 136 players.

union and intersection of sets
Answers
Answer:
The union of two sets contains all the elements contained in either set (or both sets). The union is notated A ⋃ B. The intersection of two sets contains only the elements that are in both sets. The intersection is notated A ⋂ B.
Answer:
UnionThe union of a set A with a B is the set of elements that are in either set A or B. The union is denoted as A∪B. For example, if A is the set {♢,♡,♣,♠} and B is the set {△,♡,♠}, then A∪B={♢,♡,♣,♠,△}.
IntersectionIntersection of two given sets is the largest set which contains all the elements that are common to both the sets. To find the intersection of two given sets A and B is a set which consists of all the elements which are common to both A and B. The symbol for denoting intersection of sets is '∩'.
Miguel reads that the average low temperature today is −4.2°F and that the average high temperature is 9.1º F.
Miguel plots the points on the number line to determine the temperature change between these two readings.
What is the temperature change?
° F
Answers
Answer: 13.3
Step-by-step explanation:
took on k12 :]
The change in today's temperature between the two readings as measured by Miguel is 13.3°F
Miguel's temperature readings :
Average low temperature = -4.2°F
Avetage high temperature = 9.1°F
The change in temperature is the difference between the two temperature readings :
Average high temperature - Average low temperature
(9.1 - (-4.2))°F
(9.1 + 4.2)°F = 13.3°F
Hence, the change in temperature reading = 13.3°F

Answer:
m<ABD = 37°
m<DBC = 58°
Step-by-step explanation:
m<ABD + m<DBC = m<ABC
2x + 23 + 9x — 5 = 95
11x + 18 = 95
-18 -18
--------------------
11x = 77
/11 /11
---------------------
x = 7
Now, plug this into the equation for m<ABD and m<DBC to find their values.
m<ABD = 2x + 23
= 2(7) + 23
= 14 + 23
= 37
m<DBC = 9x — 5
= 9(7) — 5
= 63 – 5
= 58
Now, check to see if our values are right or not.
2x + 23 + 9x — 5 = 95
2(7) + 23 + 9(7) — 5 = 95
14 + 23 + 63 – 5 = 95
100 – 5 = 95
95 = 95 CORRECT
