The equation that should be solved in order to find x is [tex]sin\ 26^\circ =\frac{x}{10}[/tex]. The correct option is C. [tex]sin\ 26^\circ =\frac{x}{10}[/tex]
Trigonometry: Solving a right triangleFrom the question, we are to determine which equation should one solve to find x
Considering the right triangle in the diagram,
Opposite = x
Adjacent = 9
Hypotenuse = 10
By SOH CAH TOA
We have that
[tex]sin\theta = \frac{opposite}{hypotenuse}[/tex]
Where θ is the angle
Then, we can write that
[tex]sin\ 26^\circ =\frac{x}{10}[/tex]
This is the equation that should be solved in order to find x
Hence, the equation that should be solved in order to find x is [tex]sin\ 26^\circ =\frac{x}{10}[/tex]. The correct option is C. [tex]sin\ 26^\circ =\frac{x}{10}[/tex]

After school activities activity number student Spanish club 19 baseball 24 drama 15 homework help 17 soccer 20 which ratio compares the numbers of students to Spanish clubs in the the total number of students
Answers
Answer:
19:95
Step-by-step explanation:
Spanish club have 19 students
Baseball have 24 students
Drama have 15 students
Home work help have 17 students
Soccer have 20 students
The first step is to calculate the total number of students
= 19 + 24 + 15 + 17 + 20
= 95 students
Since the Spanish club have 19 students and the total number of students is 95 then, the ratio which compares the number of students in Spanish club to the total number of students is 19:95
Answer: 19:95, 19 to 95, or 19/95. They all equal the same so it depends which one is your option. ORDER OF RATIO MATTERS!!
Explanation: The students in the Spanish club are 19 and to find the total number of students, you add 19 + 24 + 15 + 17 + 20 which equals 95. Then you put 19 first then 95. This is because it asked to compare the number of students in the Spanish clubs (so this is first) to the the total number of students (so this is second).
En una clase de 25 alumnos hay 15 cajas de lápices de colores. Cada caja contiene 20 lápices. Queremos que todos los alumnos tengan el mismo número de lápices. ¿Cuántos lápices tendrá cada alumno?
Answers
Answer: Each student will have 12 pencils.
Step-by-step explanation:
Given: Total students= 25
Total colored boxes = 15
Total pencils in 1 box =20
Then total pencils in all 15 boxes = 20 × 15 = 300
Now, the number of pencils each students will get = (Number of pencils in all 15 boxes) ÷ (Total students)
= 300÷ 25
= 12
Therefore, Each student will have 12 pencils.

What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The slope of line AB is m=2+1/-4+8
m=3/4

russell bought a CD player that costs $120 before it went on sale for 15% discount. If he paid 5% sales tax on the sale price, how much did russell pay for the cd player?
Answers
Answer:
$107.10
Step-by-step explanation:
The original price of the CD player is $120 and we need to take 15% off.
We can find how much we need to subtract by multiplying 120 by .15, which equals 18. Then we can subtract that from 120, to get a sales price of $102.
A shortcut is subtracting 15 from 100 to get 85, and then doing 120*.85 = 102.
From the sales price of 102, there's a 5% tax to add on. 102 * .05 = 5.1
102+5.1 = 107.1
Answer:
$107.10
Step-by-step explanation:
First, find the discount.
Multiply the discount rate, 15% by the price of the CD player, $120
discount rate * price
15% * $120
Convert 15% to a decimal. Divide 15 by 100 or move the decimal place two spots to the left.
15/100= 0.15 or 15.0 --> 1.5 --> 0.15
0.15 * $120
$18
Since it is a discount, subtract $18 from the regular price of $120.
$120-$18
$102
Next, find the tax.
Multiply the tax rate, 5% by the price of the discounted CD player, $102
tax rate * discounted price
5% * $102
Convert 5% to a decimal. Divide 5by 100 or move the decimal place two spots to the left.
5/100= 0.05 or 5.0 --> 0.5 --> 0.05
0.05* $102
$5.10
Since it is tax, add $5.10 to the discounted price of $102.
$102 + $5.10
$107.10
Russell will pay $107.10 for the CD Player after a discount and tax.

Which equation shows the inverse property of multiplication? 4 + (-4) = 0 -8 + (-3) = -3 + (-8) 2 times one-half = 1 Eight-fifths + 0 = Eight-fifths
Answers
Answer:
2 times one-half = 1
Step-by-step explanation:
In order to show a property of multiplication, the equation must involve multiplication. There is only one choice that does.
2 times one-half = 1
__
The multiplicative inverse of a number, multiplied by the number, results in 1, the multiplicative identity element.
Equation C,2 times one-half = 1 shows the inverse property of multiplication. Option C is correct.
What is multiplicative inverse?A multiplicative inverse is a number whose value is equal to 1 when multiplied by the original number.
The left-hand side of the equation is;
LHS = 2 times one-half
LHS = 2×(1/2)
LHS = 2
The right-hand side of the equation is;
RHS =1
If both LHS and RHS are equal and the RHS value is equal to 1 the RHS is the multiplicative inverse of LHS.
Equation C,2 times one-half = 1 shows the inverse property of multiplication.
Hence, option C is correct.

the side length of a square measures 2 x+1 and the side lengths of a triangle are 2x, 2x, and 3x+10.The square and triangle have the same perimeter. Find the perimeter
Answers
Answer:
perimeter = 52
Step-by-step explanation:
side of square = 2x + 1
so first lets find the perimeter of squarep = 4 × s (side)
p = 4(2x +1)............. from the given
p = 8x + 4...... we will come back for this equation
side of trianles = 2x,2x,3x + 10
second lets find the perimeter of trianglep = s + s + s ( all the three sides)
p = 2x + 2x + 3x + 10
p = 7x + 10........we got another equation we will use it later
The question says the perimeter of square and the perimeter of triangle are equal so8x + 4(the perimeter of square we solved before) = 7x + 10(the perimeter of triangle we solved before)8x + 4 = 7x + 10
8x - 7x = 10 - 4
x = 6 ... now lets substitute x
8x + 4
8 × 6 +4
48 + 4
52
the same thing will happen if we substitute for the perimeter of triangle too.

The diagonal of a square is 10m long. What is the length of the side of the square?(Give your answer to the nearest cm)
Answers
Explanation:
Form: d = a sqrt(2)
Where d = diagonal = 10m and a = side length
10 = a sqrt(2)
10/sqrt(2) = a
Rationalize the denominator:
10/sqrt(2) x sqrt(2)/sqrt(2)
= 10 sqrt(2)/2
= 5 sqrt(2)
Thus, a = 5 sqrt(2)m
Change to cm:
5 sqrt(2) x 100cm = 500 sqrt(2)cm
