Answer:
10.4
Step-by-step explanation:
We can use the Pythagorean theorem to solve for the unknown side since this is a right a triangle.
a^2 +b^2 =c^2
where a and b are the sides and c is the hypotenuse
6^2 + x^2 =12^2
36+x^2 = 144
Subtract 36 from each side
36-26+x^2 =144-36
x^2 =108
Take the square root of each side
sqrt(x^2) = sqrt(108)
x = sqrt(108)
x =10.3923
x =10.4 rounding to the nearest tenth
You would not subtract 2 from 6 because they are not like terms that you can combine - one of them contains a variable.
You would solve this equation like so:
6z - 2 = 0 The given equation
6z = 2 Add 2 to both sides
z = 1/3 Divide both sides by 6
Answer:
z = 1/3
Hope this helps.
When using distributive property for this it’s gonna be 5(5.75+4.25)
So 5•5.75=28.75
5•4.25=21.25
So then 28.75+21.25=50
Answer:
7 students.
Step-by-step explanation:
To pass science, a student requires at least 70 grades so students who scored below 70 will be failed.
From the given bar chart we can calculate the number of students who scored below 70 grades
Students who earned 50 - 59 = 2
Students who earned 60 - 69 = 5
Therefore, number of students who failed were
2 + 5 = 7 students.
Hello!
<h3><em><u>Answer</u></em></h3>
The area of the right triangle is 30 
. The perimeter is 40 in.
<h3><em><u>Explanation</u></em></h3>
First, we must find the measure of the hypotenuse of the triangle by using the Pythagorean Theorem.
+ 
64 + 225 = 
√289 =
17 = 
Now that we have all the side lengths, we can use the formulas to find the area and perimeter.
<h3>AREA:</h3>
A = 
A = (15 × 8) ÷ 2
A = 30
<h3>PERIMETER:</h3>
P = a + b + c
P = 8 + 15 + 17
P = 40
