Answer:
1 unique
Step-by-step explanation:
Given the angles of the triangle in the question, only one unique triangle can be formed.
This is because, if we look at the angles given, we can see that we have two of the angles equal.
This will give rise to the formation of an isosceles triangle which is a triangle in which two of the sides are equal in length
The equal angles made it in such a way that this is the only type of triangle that can be formed from the angles given

Solve for the letter A. ab+d=c
Answer:
a=c/b-d/b
Step-by-step explanation:
Answer:
a=c-d/b
Step-by-step explanation:
We first need to isolate the variable "a" by doing the opposite operation.
1. subtract "d" on both sides
After step 1- ab=c-d
2. divide both sides by "b" because that is the only way to isolate a permanently
After step 2- a=c-d/b
Solve for x.
50x + 54 = 34x + 46
Answer:
x = -1/2
Step-by-step explanation:
50x + 54 = 34x + 46
Subtract 34x from each side
50x-34x + 54 = 34x-34x + 46
16x +54 = 46
Subtract 54 from each side
16x+54-54 = 46-54
16x = -8
Divide by 16
16x/16 = -8/16
x = -1/2
Answer:
[tex]x=-\frac{1}{2}[/tex]
Step-by-step explanation:
So we are given an equation and we are asked to solve for x.
50x + 54 = 34x + 46
Subtract 54 from both sides.
50x = 34x - 8
Subtract 34x from both sides.
16x = -8
Divide both sides by 16.
[tex]x=-\frac{1}{2}[/tex]
So now we have solved for x. We have found that [tex]x=-\frac{1}{2}[/tex].

Complete Question
Engineers must consider the breadths of male heads when designing helmets. The company researchers have determined that the population of potential clientele have head breadths that are normally distributed with a mean of 6.4-in and a standard deviation of 0.9-in.If you were to draw samples of size 47 from this population, in what range would you expect to find the middle 50% of most averages for the breadths of male heads in the sample
Answer:
The range is from [tex] \=x_1 = 6.312 [/tex] to [tex] \=x_2 = 6.488 [/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 6.4 \ in[/tex]
The standard deviation [tex]\sigma = 0.9 \ in[/tex]
The sample size is n = 47
Generally the standard error is mathematically represented as
[tex]\sigma_{\= x} = \frac{0.9}{\sqrt{47} }[/tex]
=> [tex]\sigma_{\= x} = 0.13128 [/tex]
Generally the proportion where the middle 50% of most average for the breaths of male heads in the sample is mathematically evaluated as
[tex]P(\= x_1 < \= X < \= x_2 ) = P(\frac{\=x_1 - \mu }{\sigma_{\= x} } < \frac{\= X - \mu }{\sigma_{\= x} } < \frac{\=x_2 - \mu }{\sigma_{\= x} } ) = 0.5[/tex]
Generally [tex]\frac{\= X - \mu }{\sigma_{\= x} } = Z(The \ standardized \ value \ of \ \= X )[/tex]
So
[tex]P(\= x_1 < \= X < \= x_2 ) = P(\frac{\=x_1 - 6.4}{ 0.13128 } <Z < \frac{\=x_2 - 6.4 }{0.13128} ) = 0.5[/tex]
From the z table the z-score of 0.5 is
[tex]z-score = \pm 0.674[/tex]
So
[tex]\frac{\=x_1 - 6.4}{ 0.13128 } = -0.674[/tex]
[tex] \=x_1 = 6.312 [/tex]
and
[tex]\frac{\=x_2 - 6.4}{ 0.13128 } = 0.674[/tex]
[tex] \=x_2 = 6.488 [/tex]

Write a function that models the following description: A man drove a total of 40 miles over a 2-hour period. (1 point)
Answer:
The function is Speed, f(t) = x/t
Step-by-step explanation:
The given information are;
The distance the man drove = 40 miles
The duration of time the man drove = 2-hours
Given that a function maps each item of the input domain to a single item of the output domain, we can have the following relation for the above parameters;
Speed = (Distance travelled)/(Time taken)
Where, speed f(t), is a function of the time taken, t, to travel a distance x
The function is therefore;
Speed, s = f(t) = x/t
Speed = 40/2 = 20 mile per hour.
Answer:
The function is Speed, f(t) = x/t

Answer:
47°
Step-by-step explanation:
a staight angle equals 180 degrees
180=6x+29+3x+124
x=3
18+29=boc
boc=47
btw, if u know how to do my question could u plz help
thx
Answer: angle BOC is 47°
Step-by-step explanation:
Supplementary angles add to 180°
6x + 29 + 3x + 124 = 180
6x + 3x + 29 + 124 = 180
9x + 153 = 180
9x = 180 -153
9x = 27
x = 3
Substitute 3 for x in ∠BOC = 6x +29
6(3) + 29 = ∠BOC
18 + 29
47° =m∠BOC

A truck is leaving a post office and heading out to deliver mail. The table shows the truck's distance d from the post office at time t. Calculate the average rate of change over the interval from 8 to 15 minutes.
Answer:
1km per minute
Step-by-step explanation:
Given the table in the picture :
The average rate of change over the interval from 8 to 15 minutes will be :
Change in distance / change in time
Change in distance between 8 and 15 minutes :
Distance d1 at 8 minutes t1 = 7km
Distance d2 at 15 minutes t2 = 14km
Average rate of change = (d2 - d1) / (t2 - t1)
Average rate of change = (14 - 7)km / (15 - 8)min
Average rate of change = 7km / 7minutes
Average rate of change = 1km per minute
Answer:
The rate of change is 1 kilometer per minute

If g(x) = 2x2 - 4, find g(-2)
Answer:
2(-2)2=0
Step-by-step explanation:
if you meant to put it a different way tell me and i can do the correct one, just because this one seems weird lol
The value of the function when x = -2 then g(-2) = 4.
What is a function?A function is defined as a relation between the set of inputs having exactly one output each. The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can be represented by mathematical symbol.
WE have been given an function as g(x) = 2x² - 4
Now plug the value x = -2 in the given function;
g(-2) = 2(-2)² - 4
g(-2) = 2 x 4 - 4
g(-2) = 8 - 4
g(-2) = 4
Therefore, the value of the function when x = -2 then g(-2) = 4.

To measure a stone face carved on the side of a mountain, two sightings 700 feet from the base of the mountain are taken. If the angle of elevation to the bottom of the face is 35 and the angle of elevation to the top is 38 , what is the height of the stone face?
Iet us say we have two right triangles. With a base of 700. The first has angle of 35o and the other has an angle of 38degree
Then we need the Height
From trigonometry
Tan = opposite/adjacent.
In this case the adjacent is 800
Tan 35 = 0.7002
Tan 38 = 0.781

The graph shows a system consisting of a linear equation and a quadratic equation. What is the solution to the system?
Can zero be a solution of a quadratic equation? Explain
- tysm pooo
Answer:
If the discriminant is less than 0, the equation has no real solution. Looking at the graph of a quadratic equation, if the parabola does not cross or intersect the x-axis, then the equation has no real solution. And no real solution does not mean that there is no solution, but that the solutions are not real numbers. The Zero-Product Property states that for all real numbers a and b, if [tex]ab=0[/tex], then a=0 or b=0.
We can The Zero-Product Property to solve a quadratic equation when we can factor the standard form of the equation. Because when we apply The Zero-Product Property to a factored quadratic equation we can find the x-intercepts of the graph of the related functions. Respectively we can find the solutions to the quadratic equation.
