Answer:
25 7/8inches
Step-by-step explanation:
The length of the rod is equal to the side length of the equilateral triangle
Let the length of the rod be x
Since an equilateral triangle has all its sides equal, its perimeter is expressed as;
P = x+x+x
P = 3x
Given x =8 5/8
P = 3(69/8)
P = 207/8
Express as mixed fraction
P = 25 7/8 inches
Hence the length of the rod used to create the bell is 25 7/8inches

7x-4+8x=6x+8 abcdefghijklmnop
Answer:
x = 4/3
Step-by-step explanation:
7x − 4 + 8x = 6x + 8
Answer:
x=[tex]\frac{4}{3}[/tex]
Step-by-step explanation:
So the equation is 7x-4+8x=6x+8. All we need to do is simplify. On the left side, 7x+8x=15x, so 15x-4=6x+8. Now, we bring the 6x from the right side to the left. When you bring a term from one side to another, you change its sign. As of now, the sign of 6x is positive, so we make it negative and move it to the left side. The new equation is 15x-6x-4=8. Simplifying the left side gives you a new equation of 9x-4=8. Now we move the -4 from the left side to the right side. We change the sign so it becomes 4 and we move it to the right. The equation is now 9x=8+4. 8+4=12, so the final equation is 9x=12. Now we divide by 9 on both sides, giving us the unsimplified answer of x= [tex]\frac{12}{9}[/tex]. We divide the numerator and the denominator by 3 and we get our final answer of x=[tex]\frac{4}{3}[/tex].
Reflection/rotation question!
Graph each inequality. anyone know
help if u can guys i’ll give u brainliest
Answer: the answer is 16 I think
Step-by-step explanation:
Answer: 16 inches
a^2+30^2=34^2
a^2+900=1156
-900 -900
a^2=256
Square both sides to cancel a^2
a=16

factorise x ^ 4 + 1/x ^ 4 - 3
Answer:
Step-by-step explanation:
Add 1 and subtract 1, so that the expression won't change.
[tex]x^{4}+\frac{1}{x^{4}}-3=x^{4}+\frac{1}{x^{4}}-3 +1 - 1\\\\=x^{4}+\frac{1}{x^{4}} - 2 + 1\\\\= (x^{2})^{2} + (\frac{1}{x^{2}})^{2}- 2 *x^{2}*\frac{1}{x^{2}} - 1\\\\[/tex]
[tex]= (x^{2} -\frac{1}{x^{2}})^{2} - 1\\\\=(x^{2}-\frac{1}{x^{2}})^{2}- 1^{2}[/tex]
(a² - b²) = (a+b)(a - b)
Here a = x² - (1/x²) and b = 1

A lake near The Arctic Circle is covered by a thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing it’s thickness to decrease at a rate of 0.2m per week. After 7 weeks, the sheet is only 2.4m thick.
Let y represent the ice sheets thickness (in meters) after x weeks.
Complete the equation for the relationship between the thickness a number of weeks.

What is the slope of y = 5x – 1?
Answer:
5
Step-by-step explanation:
The equation of a line is y=mx+b. b is the y-intercept when the line is graphed. The y-intercept is when the line intersects the y-axis. m is the slope of the line. In the given equation, m is equal 5, thus the slope is 5.
