Andrew is using three pieces of scrap wood to build a wall shelf in his bathroom. The shelf will be shaped like a triangle, and the pieces of scrap wood measure 12 inches, 15 inches and 9inches long. Will the shelf be shaped like a right triangle? *
yes or no
Answer:
The answer is yes
Step-by-step explanation:
12=a
9=b
15=c
a+b=c
Solve for x. Then find the side lengths of the triangle. If needed, round to the nearest tenth of a foot.
40 ft
Bx ft
6x ft
side lengths =
ft and
Answer:
The side lengths are 17.9 feet and 35.8 feet
Step-by-step explanation:
Given lengths are;
40 feet, 3x feet and 6x feet
As the given triangle is right angled,
a = 3x, b = 6x and c = 40
Using Pythagorean theorem;
[tex]a^2+b^2=c^2\\(3x)^2+(6x)^2=(40)^2\\9x^2+36x^2=1600\\45x^2=1600\\[/tex]Dividing both sides by 45
[tex]\frac{45x^2}{45}=\frac{1600}{45}\\x^2=35.55[/tex]
Taking square root on both sides
[tex]\sqrt{x^2}=\sqrt{35.55}\\x=5.96[/tex]
Side lengths = 3x = 3(5.96) = 17.9 feet
and
6x = 6(5.96) = 35.8 feet
Hence,
The side lengths are 17.9 feet and 35.8 feet
Answer:
x=6

Math question highschool
Answer:
3589.85763 meters
Step-by-step explanation:
Essentially, we must have e^(-0.00012h) = 0.65 since 0.65 = 65%
Taking natural log of both sides, we get
-0.00012h = -0.430782916
0.00012h = 0.430782916
h = 3589.85763
Answer:

lee spent $26.85 for 3 yards of material what was the cost of 9 yards?
Answer:
$80.55
Step-by-step explanation:
Answer: $80.55
Step-by-step explanation:
First way:
3 yards cost $26.85
1 yard will cost $26.85 ÷ 3
26.85 ÷ 3 = 8.95
1 yard costs $8.95
9 yard will cost $8.95 × 9
8.95 × 9 = 80.55
9 yards cost $80.55
Second way:
3 yards cost $26.85
9 yards will cost $26.85 × 3
26.85 × 3 = 80.55
9 yards cost $80.55
Hope this helped!

A ticket to see your favorite baseball team costs $43.13. That price decreases by $0.45 for every game lost during the regular season. What equation could you use to find the cost C of a ticket after L losses? Represent the total change in the cost of a ticket after the team loses 39 games. What is the price of a ticket after the team loses 39 games?
Answer:
$25.58
Step-by-step explanation:
39 * 0.45= 17.55
43.13 - 17.55= $25.58
Find the value of x.
Answer:
x = 12
Step-by-step explanation:
it's indicated that all angles of this triangle are congruent; this means the triangle is called a 60-60-60 where all angles are 60 degrees.
If a triangle is equiangular then it is also equilateral, which means that if all angles are equal then all sides are equal.

B. 4
Step-by-step explanation:
Hypotenuse (h) = 5
base (b) = 3
perpendicular (p) = a = ?
We know by using Pythagoras theorem we get
p = √( h² - b²)
= √ ( 5² - 3²)
= √ (25 - 9)
= √16
= 4

Triangle K L J is cut by line segment N O. Line segment N O goes from side L K to side L J. The length of L N is (x minus 3) inches, the length of N K is (x + 2) inches, the length of L O is (x minus 4) inches, and the length of O J is x inches. Which value of x would make Line segment N O is parallel to line segment K J? 1 6 8 10
Answer: x= 8
Step-by-step explanation:
According to the converse of basic proportionality theorem,
If in ΔABC , DE is a line drawn from AB to AC such that [tex]\dfrac{AD}{DB}=\dfrac{AE}{EB}[/tex]
then, DE is parallel to the third side BC.
Applying converse of basic proportionality theorem, to get NO parallel to KJ, we must have
[tex]\dfrac{LO}{OJ}=\dfrac{LN}{NK}\\\\\Rightarrow \dfrac{x-4}{x}=\dfrac{x-3}{x+2}\\\\\Rightarrow\ (x-4)(x+2)=x(x-3)\\\\\Rightarrow\ x^2-2x-8=x^2-3x\\\\\Rightarrow\ -2x+3x=8\\\\\Rightarrow\ x=8[/tex]
Hence, the value of x should be 8, so that Line segment N O is parallel to line segment K J.

0.75x — 13 = 2
What's the value of x
Answer:
The value of x is 20.
Step-by-step explanation:
The steps are :
0.75x - 13 = 2
0.75x = 2 + 13
0.75x = 15
x = 15 ÷ 0.75
x = 20

What is the equation of the line that passes through the point (5,−2) and has a slope of -2/5
Answer:
y= -(2/5)x
Step-by-step explanation:
When you graph this line you can see it clearly passes through the point (5,-2)
Answer:
y + 2 = -2/5 (x - 5)
OR
y = (-2/5)x
Step-by-step explanation:
There are many ways you can find the equation.
There are two main ones, one called point-slope form, and the other called slope intercept form.
Point-slope form is easy. All you need a a point on the line, and the slope! Since they give you that in the question, all you need to do is plug things in.
Point slope form is y - [tex]y_{1}[/tex] = m(x - [tex]x_{1}[/tex])
x and y are any points. [tex]x_{1}[/tex] and [tex]y_{1}[/tex] are the points that the problem gives you. m is the slope.
The equation would be y + 2 = -2/5 (x - 5).
Slope intercept form is a bit harder. You need a point and the y-intercept.
Since you already have the slope, all you need to find is the y-intercept.
Slope intercept form is y = mx + b
x and y are the given points. m is the slope, and b is the y-intercept.
The y intercept is when the x value of a point is 0.
To find b, you can plug in the information you have, which is the point and the slope.
y = mx + b
-2 = (-2/5)(5) +b
-2 = -2 +b
b = 0
Since b is 0, the equation would just be y = (-2/5)x.

Given:
In an isosceles triangle,
One base angle = (4x-15)°
Vertex angle = 95°
To find:
The value of x.
Solution:
Let the triangle be ABC.
We have,
[tex]m\angle A=95^\circ[/tex]
[tex]m\angle C=(4x-15)^\circ[/tex]
Since ABC is an isosceles triangle and AB=AC, therefore, the base angles are equal.
[tex]m\angle B=m\angle C=(4x-15)^\circ[/tex]
Using angle sum property of triangles, we get
[tex]m\angle A+m\angle B+\angle C=180^\circ[/tex]
[tex]95^\circ+(4x-15)^\circ+(4x-15)^\circ=180^\circ[/tex]
[tex](8x+65)^\circ=180^\circ[/tex]
[tex](8x+65)=180[/tex]
On further simplification, we get
[tex]8x=180-65[/tex]
[tex]8x=115[/tex]
[tex]x=\dfrac{115}{8}[/tex]
[tex]x=14.375[/tex]
Therefore, the value of x is 14.375.
