x = 18Explanation:
Line E B C Needs To Equal 180°Create An Equation3x + 5 + 3x + 4 + 3x + 9 = 180
Simplify Both Sides Of The Equation(3x + 3x + 3x) + (5 + 4 + 9) = 180( Combine Like Terms)
9x + 18 = 180
9x + 18 = 180
Subtract 18 From Both Sides9x + 18 − 18 = 180 − 18
9x = 162
Divide Both Sides By 9
9x / 9 = 162 / 9

I'm having trouble with the second to last step in the fifth question.
1
1 1
x 1 1 (This is a right triangle)
1 69° 1
1-------------1
11
1. first identify a trigonometric ratio that will make it possible to find the value of x.
Answer = X is opposite to the angle 69° and 11 is adjacent to the angle 69°
2. To find the unknown value, which trigonometric function should be used?
Answer = Tangent
3. Use the tangent ratio for TAN 69°.
Answer = TAN 69° = [tex]\frac{x}{11}[/tex]
4. Multiply both sides by 11.
TAN 69° = [tex]\frac{x}{11}[/tex]
Answer = 11 · TAN 69° = x
5. Simplify
11 · TAN 69° = x
11(2.6051) ≈ x
(Blank) ≈ x
Answer = 28.7 ≈ x < -- (Rounded to the nearest tenth)
11(2.6051) ≈ x This is the part I'm having trouble with. I don't understand how to get the decimal in the parenthesis. I've tried dividing, multiplying, multiplying and then dividing. I just can't get the correct answer. I think I'm suppose to use a geometry calculator and input TAN then multiply(or divide I don't know), but I don't have one right now so I need to know if there's any way I could get the same answer with a regular calculator.

The function below shows the cost of a hamburger with different numbers of toppings (t). f(t) = 1.90 + 1.40t What is the y-intercept, and what does it mean?
Answers
Answer:
[tex]1.9[/tex]
the cost of the hamburger will be [tex]\$1.9[/tex] if no toppings are added.
Step-by-step explanation:
The function is
[tex]f(t)=1.9+1.4t[/tex]
Let cost of toppings be [tex]y[/tex]
[tex]y=1.9+1.4t[/tex]
The y-intercept of a function is the value of the function when [tex]x=0[/tex]. Here number of toppings [tex]t=0[/tex].
So, the intercept of the function is [tex]1.9[/tex]
This means the cost of the hamburger will be [tex]\$1.9[/tex] if no toppings are added.

What are the one-sided limits around the discontinuity
shown in the graph?
Answers
The one-sided limits around the discontinuity shown in the graph are infinity and zero i.e. option 2.
What is a discontinuous function?Discontinuous functions are functions that do not have a continuous curve - there is a hole or jump in the graph.
In the shown graph of the function, the function is discontinuous at x=-3
[tex]\lim_{x \to \ -3} g(x)[/tex] tends to infinity so [tex]\lim_{x \to \ -3} g(x)[/tex] does not exist.
[tex]\lim_{x \to \ +3} g(x)=0[/tex]
Hence, the one-sided limits around the discontinuity shown in the graph are infinity and zero i.e. option 2.

Jesse measured his height to be 67 inches. His actual height is 68.5 inches. What is the percent error for Jesse's measurem
Answers
Answer:
2.24%
Step-by-step explanation:
Given that :
Actual height = 68.5
Measured height = 67
Percentage error :
(Error value / True value) * 100%
Error = Actual - observed = (68.5 - 67) = 1.5
Percentage error :
(1.5 / 67) * 100%
0.0223880 * 100%
= 2.2388%
= 2.24%

solve for x -1/2x + 1/3 > 3/5
Answers
Answer:
x > 8/15
Step-by-step explanation:
x -1/2x + 1/3 > 3/5
Combine like terms
2/2x - 1/2x +1/3 > 3/5
1/2x + 1/3 > 3/5
Subtract 1/3 from each side
1/2x + 1/3 -1/3 > 3/5 -1/3
1/2x > 3/5 -1/3
Get a common denominator
1/2x > 9/15 - 5/15
1/2x > 4/15
Multiply each side by 2
2 * 1/2x > 4/15 * 2
x > 8/15

13 ,85
Answers
Answer:
84
Step-by-step explanation:
I just use an online calculator.-
www.calculator.net/triangle-calculator
So, P² = H² - B²
Or, x² = 85² - 13²
Or, x² = 7225 - 169
Or, x² = 7056
i.e x = = 84
Hence, the third number to make it right triangle = 84 Answer
Is 3(5x - 4) = 15x - 12 a one solution , no solution or infinite solutions
Answers
Answer:
Infinite Solutions
Step-by-step explanation:
3(5x - 4) needs to be simplified
So we multiply 5x by 3
So 3 x 5x = 15x
Then we multiply -4 by 3
3 x -4 = - 12
Put those together we get 15x - 12
The same equation as the one on the right side
So since 15x - 12 = 15x - 12, the x variable can be any number

How can an area model help you set
up an equation for a problem situation?
Answers
Answer: In mathematics, an area model is a rectangular diagram or model used for multiplication and division problems, in which the or the and define the length and width of the rectangle.
We can break one large of the rectangle into several smaller boxes, using number bonds, to make the calculation easier. Then we add to get the area of the whole, which is the or quotient.
Step-by-step explanation:
For example, you can find the product 23 × 37 by finding the area of a rectangle with a width of 23 and a length of 37: Of course, there is little gained if you simply multiply 23 × 37! What makes the area model useful is that area is a conserved quantity.
What is the area of the following circle?
Answers
Answer:
78.53
Step-by-step explanation:
[tex]\pi[/tex] x [tex]5^{2}[/tex]
Answer:
78.5
Step-by-step explanation:
The formula for the area of a circle is A=πr^2. The radius, (r) is half of the diameter. The diameter of this circle is 10 in, so the radius is 5 in. Plug 5 into the formula A=πr^2 to get A=π5^2. Square 5 to get 25 and plug it back in the formula to have A=25π. Multiply pi (π, 3.14) by 25 to get 78.5.

Answers
Answer:
0.98
Step-by-step explanation:
Below is a drawing of the triangle (drawing it out is an important step if you have trouble visualizing it).
Sine = opposite/hypotenuse, in this case, SR (60) is the opposite of angle Q and RQ (61) is the hypotenuse.
Sin(angle Q) = 60/61 = 0.98
