Find the value of x in the isosceles triangle
Step-by-step explanation:
Since all 3 sides of the triangle is equal, it is not only an isosceles, but an equilateral triangle.
x = 8sin60° = 6.928 or sqrt48.
That is a question about triangles.
In my answer I will show 2 ways to solve that question, ok? Let's go.
First way - Pythagoras's theoremThe line segment x divide the biggest triangle in 2 equals right triangles.
Let's choose one of them and note that is a triangule with hypotenuse equals to 8 and one cathetus equals to half of 8.
The Pythagoras's theorem says that:
[tex]\boxed{a^2 = b^2 + c^2}[/tex]
a is the hypotenuse and b and c are cathetus.
So, in our case, we know the hypotenuse and one cathetus, let's substitute that in the expression:
[tex]a^2 = b^2 + c^2\\8^2 = 4^4 + c^2\\64 = 16 + c^2\\c^2 = 64 - 16\\c^2 = 64 -16\\c^2 = 48\\c = \sqrt{48}\\c= 4\sqrt{3}[/tex]
Therefore, the value of x is [tex]4\sqrt{3}[/tex].
Second way - The equilateral triangle heightThat way to solve the question is a consequence of the previous way.
That triangle has all the sides equals, so it is a equilateral triangle.The line segment x is the height of that triangle. And we can find the equilateral triangle height using that expression:
[tex]\boxed{h = \frac{S\cdot \sqrt{3} }{2} }[/tex]
h is the height and S is the triangle's side.
So, we know that the side of our triangle is 8. Let's change S value in the expression:
[tex]h = \frac{S\cdot \sqrt{3} }{2} \\h = \frac{8\cdot \sqrt{3} }{3} \\h = 4\sqrt{3}[/tex]
Thus, the value of x is [tex]4\sqrt{3}[/tex].
Note that in the 2 ways we find the same result, so that answer is correct.
I hope I've helped. :D

-3x + 5 < -19
Explanation: Just like any of your two-step equations,
in this inequality, start by isolating the x term which in this
case is -3x by subtracting 5 from both sides.
That leaves you with -3x < -24.
To get x by itself, divide both sides by -3 but watch out.
When you multiply or divide both sides of an inequality by a
negative number, you must switch the direction of the inequality sign.
So we have x < 8 and put your final answer in
set notation and it look like this → {x: x < 8}.

Which of the following is equivalent to 7^-2?
Answer:
C
Step-by-step explanation:
Answer:
C. [tex]\frac{1}{49}[/tex]
Step-by-step explanation:
When one puts a number to a negative exponent, such as;
[tex]a^{-b}[/tex]
One is essentially doing;
[tex]\frac{1}{a^{b}}[/tex]
Applying that knowledge;
[tex]7^{-2} \\= \frac{1}{7^{2}}\\= \frac{1}{49}[/tex]

Step-by-step explanation:
Basically all you have to do is combine those equations. How do you do that? You add/subtract the equations from each other, OR use substitution. It's hard to explain I recommend searching it up.
However, in this equation this is not what they are asking for. Only ONE equation has a solution when combined/substituted. Some have false solutions such as 3=0, which is not true. Some have infinite solutions where every number works.
Solving A:
This works because it actually gives us the value of y and x instead of giving us an incorrect statement.
Solving B:
This works as well!
Solving C:
This has no solution. It doesn't work and it ends up with 0 = -6, which is not true.
Solving D:
This has more than 1 solution.
Solving E:
This does not work, it has no solutions. It ends up with 0 = -2.
What is the value of the function at x=3
Answer:
4
Step-by-step explanation:
Since the line of the function is passing through the point (3, 4).
Here x = 3 and y = 4
So the value of the function at x=3 is 4.
Ethan is planning flowers in boxes East flower box can hold 4 Ethan wants to plan 38 red flowers and 33 white flowers in the flower boxes what is the fewest number of flower boxes he would need to plant all the flowers
Answer:
18 flower boxes
Step-by-step explanation:
Given that:
Capacity of each flower box = 4
Number of flowers to plant :
Red = 38
White = 33
Total = (38 + 33) = 71 flowers
Fewest number of flower boxes needed to plant all flowers :
Total flowers to plant / capacity of each plant
71 / 4
= 17.75
= 18 boxes

If f(x) = 2x, which of the following shows the graph of f(x) = 2(x) + 2?
Answer: the first graph
Step-by-step explanation:
The intersection of the graph of the function with the y-axis gives the y-intercept of that function. The correct option is A.
What is the y-intercept of a function?The intersection of the graph of the function with the y-axis gives the y-intercept of that function. The y-intercept is the value of y on the y-axis at which the considered function intersects it.
Assume that we've got: y = f(x)
At the y-axis, we've got x = 0, so putting it will give us the y-intercept.
Thus, y-intercept of y = f(x) is y = f(0)
Given f(x)=2, therefore, the graph will have a y-intercept as 0.
But when the value of f(x) = 2(x) + 2, then the graph of the function will have the y-intercept at 2.
Hence, the correct option is A.

While on vacation in Bloomington, Ashley went out for a dinner that cost $20. If sales tax in Bloomington is 10% and Ashley left a 15% tip on $20, what was the total cost of her meal?
Answer:
$25
Step-by-step explanation:
Given that:
Cost of Ashley's dinner in Bloomington = $20
Sales tax = 10%
Tip = 15% on $20
To find:
Total cost of the meal ?
Solution:
Let us find the sales tax first of all.
Sales tax is 10% of the total bill.
Therefore, sales tax = 10% of $20
[tex]\Rightarrow \dfrac{10}{100}\times 20\\\Rightarrow \$2[/tex]
Tip left is 15% of the total bill.
Therefore, tip = 15% of $20
[tex]\Rightarrow \dfrac{15}{100}\times 20\\\Rightarrow \$3[/tex]
Now, total cost of the meal = Food cost + Sales tax + tip
Total cost of the meal = $20 + $2 + $3 = $25
