Determine whether each triangle with sides of given lengths is a right
triangle. Justify your answer. (Example 3)
30 cm, 122 cm, 125 cm
5
Answer:
It is not.
Step-by-step explanation:
The formula of a right triangle is "[tex]a^{2}+b^{2} =c^{2}[/tex]" where c is the hypothenuse (the longest side of the triangle) if we replace the formula with the values we will get
"[tex]30^{2} +122^{2} =125^{2} \\900 + 14884 = 15625\\15784\neq 15625[/tex]
Which of these needs to be completed first in order to construct a circle that circumscribes a triangle?
A. the perpendicular bisectors of any two sides of the triangle
B. the lines perpendicular to any two sides of the triangle
C. the altitudes of any two sides of the triangle
D. the medians of any two sides of the triangle
Step-by-step explanation:
step 1. draw a perpendicular bisector for 2 sides of a triangle.
step 2. where they cross is the center of the circle.
step 3. construct a circle starting at one triangle point and the circle will connect all triangle points.

find the dot product of the uv given: u v=
9514 1404 393
Answer:
19
Step-by-step explanation:
u =<2,5> v=<7,1>
The dot product is the scalar sum of products of corresponding components:
u·v = 2·7 + 5·1 = 14 +5 = 19
The dot product is 19.

Brad has a garden with dimensions 12 feet long x 7 feet wide. He wants to enlarge the garden to an area of 119 square feet. How much farther will he need to extend the length of the garden to attain his desired
Answer:
the length will need to be increased by 5 feet
He will need to 5 feet extend the length of the garden to attain his desired.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Brad has a garden with dimensions 12 feet long x 7 feet wide.
And, He wants to enlarge the garden to an area of 119 square feet.
Now,
Let the number of additional feet added to the length = x
So, We can formulate;
⇒ 7 (12 + x) = 119
⇒ 84 + 7x = 119
⇒ 7x = 119 - 84
⇒ 7x = 35
⇒ x = 5
Thus, He will need to 5 feet extend the length of the garden to attain his desired.

Find the area of a triangle with the following sides
Step-by-step explanation:
step 1. The easiest way is to use Herons formula.
step 2. s = (a + b + c)/2 = (3 + 5 + 6)/2 = 7
step 3. A = sqrt(7(7-4)(7-5)(7-6))
step 4. A = sqrt(7(3)(2)(1))
step 5. A = sqrt(42)
step 6. A = 6.4807 = 6.5cm^2.

INEQUALITIES PLEASE HELP!!!
The record for the most rolls of wrapping paper sold for the school fundraiser is 593. Let w = the number of rolls of wrapping paper sold.
Choose Yes or No to tell if each inequality represents a number that would beat the school record.
w ≥ 593 (YES OR NO?)
w > 593 (YES OR NO?)
w ≤ 593 (YES OR NO?)
593 < w (YES OR NO?)
Answer:
The record is 593.
To beat the record you need a greater number:
w > 593Options:
w ≥ 593 NO, it includes 593 w > 593 YES w ≤ 593 NO, it includes 593 and smaller numbers 593 < w YESEASY MATH PLS HELP !!!

17 + 4x = 94. Solve for x.
______________________________
1.) Subtract 17 from both sides:[tex]17-17=[/tex] Cancels Out[tex]94-17=77[/tex]
- We do this to get 1 number left over at the end sum of the equation. To do this you do the opposite of what you see. In this case we have a positive 17, so you subtract 17 on each side.
2.) Divide both sides by 4:[tex]4x[/tex] ÷ [tex]4=x[/tex][tex]77[/tex] ÷ [tex]4=19.25[/tex]
- We do this to get x alone. To do this you do the opposite of what you see. In this case we have [tex]4(x)[/tex] being multiplied, so you divide by 4 on each side.
So your answer is [tex]\bold{19.25}[/tex].
______________________________
Answer:
x= 77/4
Step-by-step explanation:
(You will first have to rearrange terms)
17+4x-94
4x+17=94
(Now you will have to subtract 17 from both sides of the equation.)
4x+17=49
4x+17-17=94-17
(You will have to simplify now)
4x=77
(You will have to divide from both sides of the equation by the same term.)
4x=77
4x=77
--- --- (Divide by 4.)
4 4
(you will now simplify)
x=77/4
and that's how you get your answer.
I hope this helps. :)
