Given: ABC is a right triangle with right angle C. AB= 14 centimeters and mA = 33°
What is AC?
Enter your answer, rounded to the nearest tenth, in the box
Answers
Answer:
AC ≈ 7.6 cm
Step-by-step explanation:
I've attached a drawing of this problem below as a visual aid.
We know that this is a right triangle (one of the angles is 90°), one of the other angles (mA) is 33°, and the hypotenuse (AB) is 14 cm. We need to calculate the length of one of the other sides. We can use sine, cosine, or tangent.
Remember SOHCAHTOA?
→ soh (Sine = Opposite / Hypotenuse)
→ cah (Cosine = Adjacent / Hypotenuse)
→ toa (Tangent = Opposite / Adjacent)
The side we want to calculate happens to be adjacent to the angle mA (33°). So, we use cosine. We put in the values we know and solve for x, the missing side:
→ sin(33°) = [tex]\frac{x}{14}[/tex]
→ x = sin(33°) × 14
→ x ≈ 7.6
The length of AC is 7.6 centimeters.

Answer:
y=1/2x-3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(0-(-4))/(6-(-2))
m=(0+4)/(6+2)
m=4/8=1/2
y-y1=m(x-x1)
y-(-4)=1/2(x-(-2))
y+4=1/2(x+2)
y=1/2x+2/2-4
y=1/2x+1-4
y=1/2x-3
In a proportional relationship when x=9 we know that y=15. Which of the following is the value of y when x=24?
(1) 30 (3) 48 (2) 40 (4) 54
Answers
Answer:
y=40
Step-by-step explanation:
x y
9 15
24 y
9/24=15/y
24*15=9y
360=9y
40=y
Therefore, 40 is correct.
If x and y are proportional, when x=24 we get y=40. Therefore, option (3) is the correct answer.
What is a proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".
Given that, in a proportional relationship when x=9 we know that y=15.
If x is directly varies to y we get
x∝y
x=ky
Now, 9=15k
k=9/15
k=3/5
So, equation is x=3/5y
When x=24, we get
24=3/5y
24×5=3y
y=40
Therefore, option (3) is the correct answer.

Help ASAP!! In which pair do both decimals represent rational numbers
Answers
Answer:
A is right
Step-by-step explanation:
The pair of both decimals that represent rational numbers is in option [tex](a)[/tex].
What are rational numbers ?A rational number is a number which is expressed as the ratio of two integers, where as the denominator should not be equal to zero [tex](\neq 0)[/tex] and are terminating and no-terminating but repeating decimals.
What are irrational numbers ?Irrational numbers can not be expressed in the form of fractions and are non-terminating and non-recurring.
We have,
[tex]0.752[/tex] and [tex]0.232323.....[/tex]
In the above given numbers [tex]0.752[/tex] is terminating, so it is a rational number.
And,
[tex]0.232323....[/tex] is non-terminating and repeating number, so it is also a rational number.
So, the pair of option [tex](a)[/tex] i.e. [tex]0.752[/tex] and [tex]0.232323.....[/tex] is the pair of rational number.
Hence, we can say that the pair of both decimals that represent rational numbers is in option [tex](a)[/tex].

===================================================
Explanation:
Since AE = BE, we know that triangle ABE is isosceles with A = B as the congruent base angles (it might help to rotate the triangle 90 degrees clockwise). The congruent base angles are always opposite the congruent sides of an isosceles triangle.
Focus on triangle ABE. Let's find the missing angle E.
A+B+E = 180
55+55+E = 180
110+E = 180
E = 180-110
E = 70
So angle BEA = 70 degrees
This means angle DEC is also 70 degrees. Angles BEA and DEC are congruent vertical angles.
--------------------
Now focus on triangle DEC. We just found E = 70. The diagram shows D = 34. Use these items to find C
D+E+C = 180
34+70+C = 180
104+C = 180
C = 180-104
C = 76
Angle C is 76 degrees

if an item sells for $44.28 per kilograms, how many cents per ounce does the item cost? Round the answer to the nearest ten-thousandth place
Answers
Answer:
The item cost 125.53159 cents per ounce if its sales price is $44.28 per kilograms
Step-by-step explanation:
The sale price of item is $44.28 per kilograms. We need it to convert into cents per ounce.
We know that 1 dollar per kilogram = 2.83495 cents per ounce
So, 44.28 dollars per kilograms = 2.83495 * 44.28 cents per ounce
= 125.53159 cents per ounce
So, the item cost 125.53159 cents per ounce if its sales price is $44.28 per kilograms

Answers
Answer:
The probability is 1/8
Step-by-step explanation:
There are two spinners here, total result on each of the two is 4
Probability of even number of the first
The even numbers are 2 and 4
Probability of an even number is 2/4 = 1/2
For the second spinner
Probability of having a 3 on the second spinner is 1/4
So the probability of an even number on the first and a 3 on the second spinner will be;
1/2 * 1/4 = 1/8

La utilidad máxima esperada por la venta de televisores en una tienda departamental para el primer mes se representa por la siguiente ecuación de utilidad U = - x2 + 500x + 100,000; obtenga las unidades y la utilidad máxima esperada por esa venta.
Answers
Explicación paso a paso:
La ganancia máxima esperada ocurre cuando dU / dx = 0
Dada la función U = - x2 + 500x + 100,000
dU / dx = -2x + 500
Dado que dU / dx = 0
Por lo tanto -2x + 500 = 0
Solución para x;
-2x = -500
x = 500/2
x = 250
Sustituya x = 250 en la función para obtener la máxima ganancia esperada como se muestra;
U = - (250) ^ 2 + 500 (250) + 100.000
U = -62500 + 125000 + 100000
U = 162,500 '
Por lo tanto, la ganancia máxima esperada por las ventas es de 162,500

At Escobar Middle School, 5% of sixth-grade students, which is 20 students, are enrolled in both art and choir. How many sixth-grade students are there in total
Answers
If 20 is 5% multiplying it by 20 would give us 100%, so 20*20=400. There are 400 sixth-grade students in total.
The total number of sixth-grade students at Escobar Middle School is 400 students
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
Let the total number of students in sixth grade = x
5 % of sixth grade students is = 20 students
So ,
We need to calculate the total 100 % students in the sixth-grade
And ,
10 % of sixth-grade students = 2 x 5 % of sixth grade students
= 2 x 20 students
= 40 students
Now ,
100 % of sixth-grade students x = 10 x 10 % of sixth-grade students
= 10 x 40 students
= 400 students
Therefore , there are 400 students
Hence , the total number of sixth-grade students is 400 students
