Your welcome!
Answer:
x = 13
Step-by-step explanation:
In order to solve this you need to know the Pythagorean theorem:
a^2 + b^2 = c^2
a - 1 side
b - 2nd side
c - hypoteneuse
Step 1: Find the missing side of the triangles
** Note both triangles are equal to each other as shown by the dashed line in both that signifies both sides are equal to each other, and the 90-degree angle there as well**
Solve:
17^2 + b^2 = 19^2
289 + b^2 = 361
361 - 289 = 72
√72 = √b^2
8.5 = b (approximately, to the tenth)
Step 2: Because both of the triangles are equal to each other, the missing side is equal to 8.5, but there are two of them, in order to determine x, you need to add both values together:
8.5 + 8.5 = 17
Then you subtract it from the base value: 31
31 - 17 = 13
Therefore, x = 13, as that is the remaining of the base.
All students in Ridgewood Junior High School either get their lunch in the school cafeteria or brought it from home on Tuesday. 5% of students brought their lunch. 36 students brought their lunch. How many students in total are in Ridgewood Junior High School?
Answer: 720
Step-by-step explanation:
5%=36
1%=36/5
1%=7.2
100%=7.2*100
100%=720 students
There is a total of 720 students are in Ridgewood Junior High School.
Given,
All students in Ridgewood Junior High School either get their lunch in the school cafeteria or brought it from home on Tuesday.
5% of students brought their lunch.
36 students brought their lunch.
To determine how many students in total are in Ridgewood Junior High School.
the percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Let there be x students in the Ridgewood Junior High School.
5% of students brought their lunch and equal to 36
so 5% of x = 36
5/100 * x = 36
x = 36*100/5
x = 36*20
x = 720
Thus, there is a total of 720 students are in Ridgewood Junior High School.

find x, find jl . any help is deeply appreciated :) !
Answer:
6. x = 15
7. JL = 78
Step-by-step explanation:
6. 8x - 23 = ½(10x + 44) (midsegment theorem)
Multiply both sides by 2
2(8x - 23) = 10x + 44
16x - 46 = 10x + 44
Collect like terms
16x - 10x = 46 + 44
6x = 90
Divide both sides by 6
x = 90/6
x = 15
7. MN = 5x - 16
JL = 4x + 34
MN = ½(JL) (midsegment theorem)
5x - 16 = ½(4x + 34) (substitution)
2(5x - 16) = 4x + 34
10x - 32 = 4x + 34
Collect like terms
10x - 4x = 32 + 34
6x = 66
x = 66/6
x = 11
JL = 4x + 34
Plug in the value of x
JL = 4(11) + 34 = 44 + 34
JL = 78

What is the remainder if f(x) = x4 – 5x2 - 6x - 10 is divided by x - 3?
Answer:-46
Step-by-step explanation: just took test
The remainder when f(x) is divided by (x - 3) is 8 and this can be determined by using the factorization method.
Given :
[tex]\rm f(x) = x^4-5x^2-6x-10[/tex]
The following steps can be used in order to determine the remainder if f(x) is divided by (x - 3):
Step 1 - Write the mathematical expression of the statement "f(x) is divided by (x - 3)".
[tex]=\dfrac{x^4-5x^2-6x-10}{x-3}[/tex]
Step 2 - Now, try to factorize the numerator in the above expression.
[tex]=\dfrac{x^4-3x^3+3x^3-9x^2+4x^2-12x+6x-18+18-10}{x-3}[/tex]
Step 3 - Further simplify the above expression.
[tex]=\dfrac{x^3(x-3)+3x^2(x-3)+4x(x-3)+6(x-3)+8}{x-3}[/tex]
[tex]=(x^3+3x^2+4x+6) +\dfrac{8}{x-3}[/tex]
So, the remainder when f(x) is divided by (x - 3) is 8.

1. Kenny is putting a brick border around his irregular shaped garden. Before installing the border, Kenny must
cut the bricks to fit the angles of the garden. Use the given measures to answer the question.
m&A = (2x + 20°
m&B= (4x - 5)
m&C = (3x + 15)°
m&D = (5x + 16)
me= (2x - 2)
What are the angle measures of each vertex of the garden? Show all calculations and work. Keep in mind that
the drawing may not be to scale.
Answer:
a=82
b=119
c=108
d=171
e=60
Step-by-step explanation:
since we can see the figure has 5 sides we can use the interior angle formula 180(n-2) and replace n for 5 getting 180(3) which woukd get us to 540. with this information we know that all the verticals have to equal 540 so we can add the equations together to get
16x+44=540 - subtract 44 from both sides to get x by itself
16x=496 - simplify
x=31
substitute x for 31 in the equations.
