Find sin X.
a. sin X= 4/5
b. sin X= 3/4
c. sin X= 3/5
d. sin X= 5/4
Answer:
sin X = 4/5
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin X = opp side/ hypotenuse
sin X = 36/45
= 4/5
Let's find the value of sin X,
→ opp/hyp
→ 36/45
→ 4/5
The required answer will be,
→ a. sin X= 4/5
So, option (a) is the answer.
Abel bought a mini hi-fi set for S600.
He sold it to Bob at a loss of 20%.
Bob sold it to Charles and made a profit of 5%. How much did Charles pay for it?
Answer:
$504
$600* .8 = $480
$480 * 1.05 = $504
Step-by-step explanation:
Answer:
Step-by-step explanation:
Abel:
Cost price = $ 600
Loss = 20%
Selling price = [tex]\frac{100-loss}{100}*Cost \ price[/tex]
[tex]= \frac{(100-20)}{100}*600\\\\=\frac{80}{100}*600[/tex]
= 80 * 6 = $ 480
Cost price for Bob = Selling price of Abel = $ 480
Bob's cost Price = $480
Selling price = [tex]\frac{100+Profit}{100}*CP\\\\[/tex]
[tex]= \frac{100+5}{100}*480\\=\frac{105}{100}*480[/tex]
= $ 504
Amount paid by Charles =$ 504

What are ways using coordinate geometry, that I could determine that this is a trapezoid?
One method to see it's a trapezoid is to find the slope of lines BC and AD.
The slope formula is
m = (y2-y1)/(x2-x1)
You should find that BC and AD both have the same slope (of -1), so that means the lines are parallel. That proves we have a trapezoid.
-----------------------
To prove this trapezoid is isosceles, you can use the distance formula
[tex]d = \sqrt{ \left(x_1-x_2\right)^2 + \left(y_1-y_2\right)^2}[/tex]
to find the lengths of AB and CD (the two non-parallel sides). You should find that AB = CD.
Because AB and CD are horizontal and vertical respectively, this means you can simply count out the spaces to find that AB and CD are 3 units each. For any other rotated version of this trapezoid, use the distance formula instead.
What is the slope-intercept form is?
Can someone help me with this math homework please!
Answer:
It's 2, 1, and y = 2x + 1.
Step-by-step explanation:
You can see the rise is 2 and the run is 1, making the slope = 2, and the y-intercept is 1 because that is where it crosses the y axis. Once you have the slope and y intercept, you can put it in a function, with the form being y=2x+1, the slope being the number before the x and the y-int value being after the x.
Answer:
1. 2
2. 1
3. y = 2x+1
Step-by-step explanation:
1. [tex]\frac{rise}{run}[/tex]
2. Where does the line cross the y-axis?
3. y = mx+b
m= slope
b = y-intercept
Scarlett tried to shade all the factors of 15 on the hundred chart.What mistake did Scarlett make? A.Scarlett shaded the factors of 5 instead of the factors of 15. B.Scarlett did not make a mistake. C.Scarlett shaded the multiples instead of the factors of 15. D.Scarlett shaded 15, but factors are always less than the number.
Answer:
C. Scarlett shaded the multiples instead of the factors of 15
Step-by-step explanation:
Scarlett tried to shade all the factors of 15 on the hundred chart 15,45,75,30,60,90 What mistake did she make
She shaded 15,45,75,30,60,90 on the chart
Factors of 15 are 1, 3, 5 and 15
15, 45, 75, 30, 60, 90 are multiples of 15
That is,
15 × 1 = 15
15 × 3 = 45
15 × 5 = 75
15 × 2 = 30
15 × 4 = 60
15 × 6 = 90
Therefore Scarlett's mistake is:
C. Scarlett shaded the multiples instead of the factors of 15

Assume that the radius of the hydrogen nucleus is 1.4 · 10-15 meters. How much larger than the nucleus is the entire hydrogen atom? (Calculate the atomic radius for n = 1. Round answer to nearest tenth.)
________times larger than the nucleus.
(A). 3.8 x 10⁴
(B). 3.8 x 10¹⁴
(C). 3.8 x 10^-5
(15 points reward)
Answer:
A
Step-by-step explanation:
I did not look up the actual numbers, but it can only be A.
of course, the whole aim is larger than the nucleus, which is why C is impossible with its negative exponent (which would make the whole aim smaller than the nucleus).
and B. can't be true, because it is so big 10¹⁴ times bigger than a 10-¹⁵ atom ? this would make the whole atom the size of about 10-¹ meters. so, 10 cm. a single hydrogen atom would be bigger than a tennis ball. which it isn't.
so, that only leaves A.
Which statement are true regarding undefinable terms in geometry
Answer:
A plane has an unlimited number of points.
Step-by-step explanation:
A plane has an unlimited number of points.
An exact solution represents a point's position on the coordinate plane (x, y).
Even though a point has no dimensionality, the second assertion is incorrect.
Because a linear has only one component, length, the third assertion is likewise incorrect.
a: A point has no length or width.
B: a point indicates a location in a coordinate plane.
E: a plane consists of an ifinite plans
F: a line consists of an infinite set of points.
5 – 2x = 3 what is x?
Answer: x=1
Step-by-step explanation:
To solve for x, we want to isoate the variable.
5-2x=3 [subtract both sides by 5]
-2x=-2 [divide both sides by -2]
x=1
Now, we know that x=1.
Answer:
X = 1
Step-by-step explanation:
Add 2x to both sides of the equation
5-2x+2x=3+2x
5+0=3+2x
Subtract 3 from both sides of the equation
5-3=3-3+2x
2=0+2x
2x=2
x=2/2
X = 1
According to the rational root theorem what are all potential rational roots of F(x)=9x^4-2x^2-3x+4
Answer:
The answer is
[tex]( + - )(1)( \frac{1}{3} )( \frac{1}{9} )(2)( \frac{2}{3} )( \frac{2}{9} )(4)( \frac{4}{3} )( \frac{4}{9} )[/tex]
Explanation:
Rational root theorem, also called rational root test, in algebra, theorem that for a polynomial equation in one variable with integer coefficients to have a solution (root) that is a rational number, the leading coefficient (the coefficient of the highest power) must be divisible by the denominator of the fraction and
and the constant term (the one without a variable) must be divisible by the numerator.
In f(x), the ratio is
[tex] \frac{4}{9} [/tex]
because 4 is the constant and 9 is leading term
So our factors are
[tex] \frac{4}{9} = \frac{ + - (1)(2)(4)}{ + - (1)(3)(9)} [/tex]

Parallelogram PARL is similar to parallelogram WXYZ. If AP = 18, PL = 24, and WZ = 96, find the value of c.
A. 4
B.96
C.42
D.72
somebody can help me
Answer: c = 72
Step-by-step explanation:
You didn't tell us which segment has a length of c, but I'm assuming you meant WX because it corresponds to PA. If two figures are similar, we know that their side length are in proportion. With this, we can set up our proportion[tex]\frac{18}{24} =\frac{c}{96}[/tex] where c is the length of WX. By cross multiplying and dividing, you get 72 for the value of c.

Answer:
108
Step-by-step explanation:
Surface area = total area of net
The net is made up of 2 unique shapes
A square with a side length of 6
The area of a square can be calculated by squaring the side length
6^2 = 36
The area of the square = 36
The net is also made up of 4 triangles
The triangles have a base length of 6 and a height of 6
The area of a triangle can be calculated by using the formula A = (bh) / 2
Where b = base length and h = height
If the triangles have a base length of 6 then b = 6 and if they have a height of 6 then h = 6
So A = 6*6/2
6 * 6 = 32
32/2 = 18
We then multiply that by 4 to get the area of all four triangles
18 * 4 = 72
Finally we add the areas together
72 + 36 = 108
The surface area is 108
