42
Step-by-step explanation:
use the Pythagorean theorem :D
Answer:
[tex] \underline{\boxed{x = 42}}[/tex]
Step-by-step explanation:
[tex] {70}^{2} = {x}^{2} + {56}^{2} \\ {x}^{2} = {70}^{2} - {56}^{2} \\ x = \sqrt{( {70}^{2} - {56}^{2} )} \\x = \sqrt{(4,900 -3,136) } \\ x = \sqrt{1,764} \\ x = 42[/tex]

Oh phone company offers to monthly plans plan a cost $13 plus an additional $.14 for each minute of calls Plan B cost $18 plus an additional of $.09 for each minute of calls.
For what amount of calling do the two plans cost the same?
What is the cost when the two plans cost the same?
Answer:
For 100 minutes
Step-by-step explanation:
Step one:
given data
Oh phone company
monthly plans plan a cost $13 plus an additional $.14 for each minute of calls
let the number of minutes be x, and the total be y
y= 13+0.14x--------------------1
Plan B cost $18 plus an additional of $.09 for each minute of calls
let the number of minutes be x, and the total be y
y= 18+0.09x--------------------2
Step two:
Equate 1 and 2 above
13+0.14x=18+0.09x
collect like terms
18-13= 0.14x-0.09x
5=0.05x
divide both sides by 0.05
x=5/0.05
x=100 minutes

the drama club is selling tickets for the spring musical each student ticket is $5 each adult ticket is $8 total of $222 tickets were sold the total ticket sells for $1,626 which system of equation can be used to represent the situation
Answer and Step-by-step explanation:
I don’t really know which system of equation to use, but I did the work. I also think there is supposed to be an attached picture but it’s fine
——————————————————————————————————————
Let x be students
Let y be adults
x + y = 222
5x + 8y = 1,626. <— let’s use the elimination/addition method to Solve this. Also, let’s eliminate y.
8 (x + y = 222)
-1 (5x + 8y = 1,626)
8x + 8y = 1,776
+ -5x - 8y = -1,626 <— add both of them
——————————————
3x = 150 <— divide 150 by 3
x = 5
Which equation is NOT a linear function?
y = 17
y=-4x – 12
y = x2-2
y = 5x
I ready
Answer:
y=x^2-2
Step-by-step explanation:
this equation is not a linear function because the equation is that of a quadratic function
3x − 2y = 18
y = 2x − 13
Answer:
x = - 8
3x - 2y = 18 is the same as 3x - (2x - 13 times 2) = 18
Then I used an algebra site for the rest.
It should be x = - 8
I'm guessing you want x and y solved.
Answer: x=10 and y=6
Explanation:
For X: Substitute the y-equation (y-2x-13) into the first equation (3x-2y=18) so your equation is 3x-2(2x-13)=18. Do the distribution property and the equation will be 3x-4x+26=18. Put like terms on the same side of the equal sign and combine like terms (subtract 26 on both sides) and the equation will be -x = -10. To make x positive, make both sides positive and you get x=10.
For Y: Substitute your x answer (10) into the first equation (3x-2y=18) and you will get 30-2y=18. Subtract 30 from both sides and you get -2y=12. Divide both sides by the common factor of -2 and you get y=6.
A study of pet owners included 752 owners who were chosen at random. Of these pet owners, 63% said they had spayed or neutered their pets. Vet records show that only 39% of pet owners spay or neuter their pets. Identify the statistic and the parameter. (4 points)

Seven hundred fifty-two is the statistic and 63% is the parameter.
Seven hundred fifty-two is the parameter and 39% is the statistic.
Answer:
Sixty-three percent is the statistic and 39% is the parameter.
Step-by-step explanation:
The statistic and the parameter are to be considered as 63% is the statistic and 39 % is the parameter.
Identification of the statistic and the parameter:Here the parameter represent the fixed measure that explained the overall population that share the related and common attributes.
And, the statistic means the attribute of the sample or the portion of the target population.
Hence, Sixty-three percent is the statistic and 39% is the parameter.

Please help me with my homework!!!!!!!
Answer:
A, C, E
Step-by-step explanation:
- (3/4) = -3/4
A: A is correct because it is the same equation as above.
B: -3/-4
The negatives cancel out each other, so it would just be 3/4, which is not the same as -3/4, so B is incorrect
C: -3/4 is equal to -3/4, so C is correct
D: -(-3/4)
The negative signs cancel each other out, so it equals 3/4. D is incorrect
E: 3/-4 = -3/4, so E is correct

1.6(1 + 0.5n) - 3, 2 = 1.1(n - 6.8)
please answer with work
Answer:
67
Step-by-step explanation:
__
Answer: 5.4945...
Step-by-step explanation:
1.6 (1 + 0.5n) − 3 , 2 = 1.1 (n − 6.8)
Rewrite the equation as 1.1 (n − 6.8) = 2.
1.1 (n − 6.8) = 2
Divide each term by 1.1 and simplify.
Divide each term in 1.1 (n − 6.8) = 2 by 1.1.
1.1 (n − 6.8)/1.1 = 2/1.1
Cancel the common factor of 1.1.
n − 6.8 = 2/1.1
Divide 2 by 1.1.
n − 6.8 = 1.81...
Move all terms not containing n to the right side of the equation.
Add 6.8 to both sides of the equation.
n = 1.81... + 6.8
Add 1.81... and 6.8.
n = 8.618...
Replace the variable n with 8.618... in the expression.
1.6 (1 + 0.5 (8.618...)) − 3
Simplify each term.
Multiply 0.5 by 8.618...
1.6 (1 + 4.309...) − 3
Add 1 and 4.309...
1.6 ⋅ 5.309... − 3
Multiply 1.6 by 5.309...
8.4945... − 3
Subtract 3 from 8.4945...
5.4945...
