Step-by-step explanation:
If the length of one base of a trapezoid is 44, the median is 36, and the other base is 2x + 10, find x.
Answer:
9
Step-by-step explanation:
The median is the average of the base lengths. Where "b" is the length of the other base, we have ...
36 = (44 +b)/2
b = 72 -44 = 28
We are told this is the same as 2x+10, so we have ...
28 = 2x +10
18 = 2x . . . . . subtract 10
9 = x . . . . . . . divide by 2
The value of x is 9.

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times the measure of the first angle. The third angle is 14 more than the second. Let x, y, and z represent the measures of the first, second, and third angles, respectively. Find the measures of the three angles.
Answer:
[tex]x=30\\y=68\\z=82[/tex]
Step-by-step explanation:
x = measure of the first angle
y = measure of the second angle
z = measure of the third angle
The sum of the measures of the second and third (y+z) is five times the measure of the first angle (=5x)
[tex]y+z=5x[/tex]
The third angle is 14 more than the second
[tex]z=y+14[/tex]
And remember that the sum of these three angles must be equal to 180.
[tex]x+y+z=180[/tex]
Let's take these equations
[tex]y+z=5x\\z=y+14\\x+y+z=180[/tex]
If you take a look at the first equation, we have y+z = 5x and we have y+z in the third equation as well, we can replace that....
[tex]x+y+z=180\\x+(y+z)=180\\x+(5x)=180[/tex]
Distribute the + sign
[tex]x+5x=180[/tex]
Combine like terms;
[tex]6x=180[/tex]
Divide by 6.
[tex]x=\frac{180}{6}\\ x=30[/tex]
We have now defined that the measure of the first angle is 30º.
Let's take another equation... for example [tex]z=y+14[/tex]
I'm going to take this one because if I replace x and z in the third equation, all I'll have left will be y.
[tex]x+y+z=180\\30+y+(y+14)=180[/tex]
Distribute the + sign and Combine like terms;
[tex]30+y+y+14=180\\44+2y=180\\[/tex]
Subtract 44 to isolate 2y.
[tex]2y=180-44\\2y=136[/tex]
Now divide by 2.
[tex]y=\frac{136}{2}\\ y=68[/tex]
We already have the value of x and y. Once again, replacing this in the third equation will leave us with z to solve for.
[tex]x+y+z=180\\30+68+z=180\\98+z=180\\z=180-98\\z=82[/tex]
Today a shoe store it’s at 20% of the price of a pair shoes and for the next three days it will take 20% of the previous days price if the price of a pair of shoes yesterday was $200 what will be the price of the pair of shoes three days from now
A.160.00
B.128.00
C.102.40
D.81.92
If the price of the shoe yesterday was $200 and on this day 20 percent has been taken thus it will have $160. In the next 3 days if another 20 percent will be taken out from the previous $160 then the final answer is $128.

Answer
8,112 ounces
Step-by-step explanation:
505 pounds converted into ounces= 8080 ounces which is not more than 8,112
Step-by-step explanation:
1 pound = 16 ounces
505 pound = 505 x 16 = 8080 ounces
So 8112 ounces weighs more

simplify [tex]\sqrt{.49x^{18} }[/tex] where x<0
Answer:
-7x⁹
Step-by-step explanation:
[tex]\sqrt{49x^{18}} = \sqrt{(7^2)(x^9)^2} =\sqrt{(7x^{9})^2} = |7x^9|[/tex]
Since x < 0 ,then |7x⁹| = -7x⁹
What is the first step in factoring polynomials
Answer:
Factor out the greatest common factor
Step-by-step explanation:
The first step when factoring any polynomial is to factor out the GCF. The GCF is the greatest common factor for all the terms of the polynomial. By factoring out the GCF first, the coefficients and constant term of the polynomial will be reduced.

B. Week 6
Step-by-step explanation:
[tex]f(x) = 2^{x}[/tex]
We know that f(x) represents number of subscribers, x represents week number. So plug in 64 for f(x).
[tex]64 = 2^{x}[/tex]
Uh-oh, how do we solve this? We need to go from exponential form to logarithmic form.
[tex]64 = 2^{x}[/tex]
log₂(64) = x
We're basically asking the question: 2 to the what equals 64? And we can plug this into the calculator as log₂(64) (on TI-84, it's MATH->logBASE(). Or you can just think about it:
2 x 2 x 2 x 2 x 2 x 2 = 64.

What is sine of an angle?The sine (sin) of an acute angle in a right angled triangle is the ratio between the side opposite the angle and the hypotenuse of the triangle.
What is cosine of an angle?In a right triangle, the cosine of an angle is the length of the adjacent side (A) divided by the length of the hypotenuse (H).
What is tangent of an angle?The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.
What is cosecant of an angle?In a right angled triangle, the cosecant of an angle is the length of the hypotenuse divided by the length of the side opposite the angle.
According to the given question.
We have a right angle triangle ABC.
In which
AB = 7
AC = 4
Now by Pythagoras Theorem
[tex]AB^{2} =AC^{2} +BC^{2}[/tex]
⇒ [tex](7)^{2} = (4)^{2} + BC^{2}[/tex]
⇒ [tex]49 = 16 +(BC)^{2}[/tex]
⇒ [tex]49 - 16=BC^{2}[/tex]
⇒ [tex]BC^{2} = 33[/tex]
⇒ [tex]BC=\sqrt{33}[/tex]
In the right angle triangle
Hypotenuse, AC = 7
The side BC is the adjacent side w.r.t angle θ.
And, Side BC is the opposite side w.r.t angle θ.
Therefore,
[tex]tan\theta=\frac{4 }{\sqrt{33} }[/tex]
[tex]cos\theta= \frac{\sqrt{33} }{7}[/tex]
[tex]sin\theta= \frac{4}{7}[/tex]
[tex]cosec\theta=\frac{1}{sin\theta} =\frac{1}{\frac{4}{7} } =\frac{7}{4}[/tex]
Hence, the exact values of [tex]cos\theta[/tex], [tex]tan\theta[/tex], and [tex]cosec\theta[/tex] are [tex]\frac{\sqrt{33} }{7}[/tex], [tex]\frac{4}{\sqrt{33} }[/tex] and [tex]\frac{7}{4}[/tex] respectively.

A sector with a radius 12 cm has an area of 60 pi cm2. What is the central angle measure of the sector in degrees?
Answer:
The central angle measure of the sector is 150º.
Step-by-step explanation:
A sector of a circle is the portion of a circle enclosed by two radii and an arc.
When you know the central angle the area of a sector is given by
[tex]A=\pi r^2(\frac{C}{360} )[/tex]
where
r is the radius of the circle of which the sector is part.
C is the central angle in degrees.
We know that the area of the sector is [tex]60\pi \:cm^2[/tex] and the radius is 12 cm. Applying the above formula and solving for the central angle we get that
[tex]60\pi =\pi (12)^2(\frac{C}{360}) \\\\\pi \left(12\right)^2\left(\frac{C}{360}\right)=60\pi \\\\\frac{\pi 12^2\cdot \frac{C}{360}}{144\pi }=\frac{60\pi }{144\pi }\\\\\frac{C}{360}=\frac{5}{12}\\\\C=150[/tex]
