find the value of xin the triangle shown below
Answer:
[tex]x=80^{\circ}[/tex]
Step-by-step explanation:
Solution 1:
Recall that in an isosceles triangle, the two angles adjacent to the congruent sides are equal. Since the sum of interior angles in a triangle add up to [tex]180^{\circ}[/tex], we set up the following equation:
[tex]x+50+50=180[/tex].
Solving, we get:
[tex]x+100=80,\\x=\fbox{$80^{\circ}$}[/tex].
Solution 2:
The Law of Sines states:
[tex]\frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}[/tex], for any triangle.
We can use this to set up a proportion with the information given:
[tex]\frac{\sin x}{18}=\frac{\sin 50^{\circ}}{14}[/tex].
Solving, we get:
[tex]x=\arcsin(\frac{18\cdot \sin 50^{\circ}}{14}),\\x \approx \fbox{$80^{\circ}$}[/tex].
Sewing patterns recommended buying extra fabric in case of mistakes. Darlene bought 7 yards of fabric, plus 20% extra fabric. Chris bought 4 yards of fabric plus 25% extra. Who bought more fabric. How much more?
Answer:
Darlene bought more fabric
Darlene bought 3.4 yards more
Step-by-step explanation:
Darlene = 7 yards + 20% extra
= 7 yards + (20% of 7 yards)
= 7 + (20% × 7)
= 7 + (0.2 × 7)
= 7 + 1.4
= 8.4 yards
Chris = 4 yards + 25% of 4 yards
= 4 yards + (25% of 4 yards)
= 4 + (25% × 4)
= 4 + (0.25 × 4)
= 4 + 1
= 5 yards
Darlene bought more fabric
How much more?
Darlene - Chris
= 8.4 yards - 5 yards
= 3.4 yards
Darlene bought 3.4 yards more

when an equation is in standard form you can easily find the x-intercept and y-intercept simply by substituting in ____ for each variable
Answer:
by substituting 0
Step-by-step explanation:
Similarly, any y-intercept will have an x coordinate of 0. Using the standard form of an equation we can easily find the intercepts. To find the x-intercept, we set y=0 and solve for x. To find the y-intercept, we set x=0 and solve for y.
We can complete the given statement as:
When an equation is in the standard form you can easily find the x-intercept and y-intercept simply by substituting 0 for each variable.
What are intercepts?Intercepts are the point of intersection, between the graph of an equation and an axis of the coordinate plane.
We have two intercepts:
x-intercept: The point at which the equation intersects the x-axis. This point is taken as (a,0), as any point on the x-axis has a y-coordinate = 0.y-intercept: The point at which the equation intersects the y-axis. This point is taken as (0, b), as any point on the y-axis has an x-coordinate = 0.How to solve the question?In the question, we are asked: when an equation is in the standard form you can easily find the x-intercept and y-intercept simply by substituting in ____ for each variable.
We know that the x-intercept has a y-coordinate = 0. Thus, when we substitute the value of y = 0, in the equation, we get the x-intercept 'a', as the point (a, 0) satisfies the equation.
We know that the y-intercept has an x-coordinate = 0. Thus, when we substitute the value of x = 0, in the equation, we get the y-intercept 'b', as the point (0, b) satisfies the equation.
Thus, we can complete the given statement as:
When an equation is in the standard form you can easily find the x-intercept and y-intercept simply by substituting 0 for each variable.

Noah already has $10.50, and he earns $3 each time he runs an errand for his neighbor. Noah wants to know how many errands he needs to run to have at least $30
Answer: 7 errands
Step-by-step explanation:
Noah wants to have at least $30. He however already has $10.50.
The amount that he needs is:
= 30 - 10.50
= $19.30
For every errand he runs, he makes $3. The number of errands needed to get to $30 is:
= 19.50/3
= 6.5

Slope is equal to the change in y over the change in x, or rise over run.

change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y
is equal to the difference in y-coordinates (also called r ise).

Substitute in the values of x and y into the equation to find the s lope.
m = −1 − (−2) /3 − (−1)
Simplify the numerator.
Multiply −1 by −2.
m = −1 + 2 /3 − (−1)
Add −1 and 2.

The length of a rectangle is 3 cm greater than its
width. Its area is 108 cm. Find the dimensions
of the rectangle.
The length is 12 cm and width is 9 cm.
what is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Area = 108 cm²
and, The length of a rectangle is 3 cm greater than its width.
let the width of rectangle be x.
so, length = x+ 3
So, Area of Rectangle = l x w
108 = x(x+ 3)
x² + 3x -108 = 0
x² + 12x - 9x -108 = 0
x( x+ 12) -9 ( x+ 12)= 0
(x + 12)(x- 9)=0
x= -12, +9
So, length is 12 cm and width is 9 cm.

Maria is bringing her sick dog, Pedro in for a series of appointments at the veterinary clinic. Her total cost over the course of treatment will be $150 for tests and medicine plus $30 per appointment "a". A) Write an equation to show the total cost, "t" she will owe. *
Answer:
t = 150 + 30a
Step-by-step explanation:
Treatment of Pedro costs = Expenditure for tests and medicines + fees given for appointments.
If number of appointments = a
Cost per appointment = $30
Cost of 'a' appointments = $30a
Therefore, equation representing the total cost 't' of the treatment will be,
t = 150 + 30a

Answer: Felix paid for 11 months.
Step-by-step explanation:
Let x = Number of months
Given: Annual fee = $ 20
charge per month = $15
Total amount = Annual fee + (charge per month) x (number of months)
[tex]\Rightarrow\ 185 = 20+15x\\\\\Rightarrow\ 165=15x\\\\\Rightarrow\ x = \dfrac{165}{15}\\\\\Rightarrow\ x =11[/tex]

The area of a rectangular pool table is: x2 + 14x +40. What are the dimensions of the table?
Formula: Area = (L) (W)
A(x + 8)(x + 5)
B(x + 20)(x - 2)
C(x + 4)(x + 10)
D(x +14)(x + 40)
Answer:
the width is (x + 4) and the length is (x + 10)
Step-by-step explanation:
The area of a rectangle is given by A = L * W, where L is the length and W the width.
If we factor the given x^2 + 14x + 40, we get (x + 10)(x + 4). Thus, the width is (x + 4) and the length is (x + 10).
