Answer:
962.5 ft²
Step-by-step explanation:
Area of landing pad = Area of circle
d = 35 ft, r = 35/2 ft
Area = [tex]\pi r^2[/tex]
[tex]\pi r^2[/tex] = [tex]\frac{22}{7} * \frac{35}{2}* \frac{35}{2}[/tex]
= 962.5 ft²
Thus area of landing pad = 962.5 ft²

Rectangle JKLM
is rotated to obtain J′K′L′M′
. Which statement is true
a.J′K′L′M′ will be a quadrilateral but not a rectangle because the measurements of line segments and angles are preserved in a rotation, but parallel lines are not.
b.J′K′L′M′ will be a parallelogram but not a rectangle because parallel lines are preserved in a rotation, but the measurements of line segments and angles are not.
c.J′K′L′M′ will be a rectangle because the measurements of line segments and angles, and the presence of parallel lines are preserved in a rotation.
d. J′K′L′M′ will not be a rectangle because the measurements of line segments and angles, and the presence of parallel lines are not preserved in a rotation
Answer:
Answer is A - Angles that are congruent are complementary to the same angle.

Choose the set that is the possible side lengths of a right triangle.
a)1,1,2 b)3,5,9 c)3,4,7 d)1,1,square root2
Answer:
D
Step-by-step explanation:
Mathematically, for us to have a right triangle, Pythagoras’ theorem must be obeyed
From the theorem, the square of the hypotenuse (longest side) equals the sum of the squares of the two other sides
Let us take a look at the given set of numbers:
2 square is not same as 1 squared + 1 squared
9 squared is not equal to 3 squares + 5 squared
7 squared is not equal to 4 squared + 3 squared
But;
root 2 squared equals 1 squared plus 1 squared and that is our answer

2 supplementary angles are in the ratio 6:3
Find the angles
Answer:
The angels are 60 degrees and 120 degrees
Step-by-step explanation:
The sum of two supplementary angels equal 180 degrees.
So, lets look at the ratio: 6:3
We then add 6 and 3 together which gives us 9.
Then you put it in this equation:
9x = 180
x= 20
- You are adding the two numbers and dividing the sum by 180 because the answer will tell us how much 1 would equal.
- In this case, we multiply 20 by 6 = 120 degrees
- Then we multiply 20 by 3 = 60 degrees.
(We can check our answer by: 120 + 60 = 180 degrees) :)

How many solutions does this equation have?
8z − 5 = 8z
Answer:
Zero
Step-by-step explanation:
Solve the equation by subtracting 8z from both sides:
8z − 5 = 8z
-5 = 0
-5 [tex]\neq[/tex] 0
This is a false statement, because -5 is not equal to zero.
This means that there are no solutions to the equation.
So, the equation has zero solutions
Because both sides of the equation have the same variable ( they both have 8x) this equation does not have any solutions.

Camille is attending a fundraiser. She pays for her admission and buys several raffle tickets.
The function S = 5r + 13 represents the total amount of money she paid, S.
and the number of tickets she bought, r. Which is a correct statement?
Camille paid total of $18 at the fundraiser.
The admission was $5.
Camille bought 13 tickets.
The admission was $13.
Answer: S=5r+85 i think try it out
Step-by-step explanation:
Answer:
The second statement.
Step-by-step explanation:
The function S = 5r + 13 means that the Total = 5 * Tickets + 13 Admission
So if Camille bought 13 tickets, the + 13 at the end means that no matter what, she had 13 dollars admission.

A student in a chemistry lab has access to two acid solution .The first solution is 20% acid and the second is 45% acid .(the percentage are by volume). How many milliliters of each solution the student mix together to obtain 100 ml of a 30% acid solution?
Answer:
x = 20% acid = 60 ml
y = 45% acid = 40 ml
Step-by-step explanation:
Let
x = 20% acid
y = 45% acid
x + y = 100 (1)
.20x + .45y = .3 ×100
.20x + .45y = 30 (2)
From (1)
x + y = 100 (1)
x = 100 - y
Substitute x = 100 - y into (2)
.20x + .45y = 30
.20(100 - y) + .45y = 30
20 - .20y + .45y = 30
- .20y + .45y = 30 - 20
.25y = 10
y = 10/.25
y = 40 ml
Substitute y = 40 into (1)
x + y = 100
x + 40 = 100
x = 100 - 40
x = 60 ml
x = 20% acid = 60 ml
y = 45% acid = 40 ml
Si un empresario paga diariamente 50 a cada trabajador le faltaria 110 pero si les pagara 45 le sobraria 60 cuantos trabajadores tiene dicho empresario
Answer:
34 trabajadores.
Step-by-step explanation:
Supongamos que el empresario tiene N trabajadores, y tiene la cantidad de dinero D para pagarles cada día.
Si el empresario decide pagarle 50 a cada trabajador le faltan 110.
Esto se puede reescribir como:
50*N = D + 110
(50 por número de empleados es igual que el dinero que tiene más lo que le falta para pagar)
También sabemos que si pagara 45 a cada empleado, le sobraría 60.
Esto se puede reescribir como:
45*N = D - 60
Entonces tenemos dos ecuaciones:
50*N = D + 110
45*N = D - 60
Para resolver esto, el primer paso es aislar una de las variables en una de las ecuaciones, en este caso aislaré D en la segunda ecuación.
45*N + 60 = D
Ahora podemos reemplazar esto en la primer ecuación y resolver para N
50*N = (45*N + 60) + 110
50*N = 45*N + 170
50*N - 45*N = 170
5*N = 170
N = 170/5 = 34
El empresario tiene 34 trabajadores.

Jordan has a bag that contains orange chews, strawberry chews, and lime chews. He performs an experiment. Jordan randomly removes a chew from the bag, records the result, and returns the chew to the bag. Jordan performs the experiment 61 times. The results are shown below: An orange chew was selected 11 times. A strawberry chew was selected 17 times. A lime chew was selected 33 times. Based on these results, express the probability that the next chew Jordan removes from the bag will be strawberry chew as a decimal to the nearest hundredth.
Answer:
17/61 or 0.27
Step-by-step explanation: 17 out of 61 times Jordan will pull out strawberry so the probability of pulling out a strawberry chew is 17/61 which is 0.27 as a decimal

2-2N=3N+17
help plz thank you
Answer:
-3 = N
Step-by-step explanation:
2-2N=3N+17
Add 2N to each side
2-2N+2N=3N+2N+17
2 = 5N +17
Subtract 17 from each side
2-17 = 5N+17-17
-15 = 5N
Divide each side by 5
-15/5 = 5N/5
-3 = N
Answer:
N= -3
Step-by-step explanation:
First, bring 3N on to the left side by subtracting 3N with 2N
2-2N-3N=17
Then, move 2 to the right side by subtracting 17 and 2: -2N-3N= 17-2
Solving the like terms gives us -5N= 15
N= 15/-5
N= -3

Determine the best method to solve the system of equations. Then
solve the system. x - 3y = 25 and 2x + y = 64. can you please help!!!!!
Answer:
(31, 2); Substitution.
Step-by-step explanation:
x - 3y = 25
Use SUBSTITUTION by setting everything in the above equation equal to x...
x = 3y + 25
2(3y +25) + y = 64
6y + 50 + y = 64
7y + 50 (-50) = 64 (-50)
7y = 14
y = 2
Then, substitute y = 2 into the original equation.
x - 3(2) = 25
x - 6 = 25
x = 31
(x, y) = (31, 2)
