Answer:
i think the given triangle is equilateral triangle because all side are equal.
Answer:
d. 0
Step-by-step explanation:
Given that:
A rational number is multiplied by a irrational number.
And the result is a rational number.
To find:
Such rational number wil be:
a. ![\frac{1}2](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D2)
b. 1
c. ![\frac{1}{10 }](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B10%20%7D)
d. 0
Solution:
Let us consider the given options one by one.
Let the irrational number be = ![\pi](https://tex.z-dn.net/?f=%5Cpi)
Checking option a.
Multiply
and
.
Result is:
which is again irrational.
So, a. is not correct.
Checking option b.
Multiply
and 1.
Result is:
which is again irrational.
So, b. is not correct.
Checking option a.
Multiply
and
.
Result is:
which is again irrational.
So, c. is not correct.
Checking option d.
Multiply
and 0.
Result is: 0 which is rational.
So, d. <em>0 </em>is the correct answer.
Hi there!
![2x + 6 {x}^{2} - 1 = 3 {x}^{2}](https://tex.z-dn.net/?f=2x%20%2B%206%20%7Bx%7D%5E%7B2%7D%20%20-%201%20%3D%203%20%7Bx%7D%5E%7B2%7D%20)
First subtract 3x^2 from both sides.
![2x + 3 {x}^{2} - 1 = 0](https://tex.z-dn.net/?f=2x%20%2B%203%20%7Bx%7D%5E%7B2%7D%20%20-%201%20%3D%200)
Now rearrange the equation.
![3 {x}^{2} + 2x - 1 = 0](https://tex.z-dn.net/?f=3%20%7Bx%7D%5E%7B2%7D%20%20%2B%202x%20-%201%20%3D%200)
Finally we can see our answer.
![a = 3](https://tex.z-dn.net/?f=a%20%3D%203)
![b = 2](https://tex.z-dn.net/?f=b%20%3D%202)
The smaller triangle has a ratio of 11 : 10.
The smaller triangle and the larger triangle should have the same ratio.
The total of the left side of the larger triangle is 132cm
The ratio of the larger triangle is:
132 : (5x + 10) + 10
132 = 5x + 20
If you multiply the 11 : 10 ratio by 12, you get:
132 : 120
Since you know the other side should equal 120, to find x you do:
5x + 20 = 120
5x = 100
x = 20
Answer:
y = 6x + 100
Step-by-step explanation:
Slope-intercept form is y = mx + b, where m is the cost to produce each item and b is the fixed cost. Let's input the given values for m and b into the equation:
y = 6x + 100
This is the cost equation. $6 multiplied by x amount of items pluss the fixed cost of $100 gives you the total cost (y) to produce x amount of items.
Hope this helps :)
