What is the the value of x. Pleaseeeee help I’ll mark you brainlist
Answer:
11.75
Step-by-step explanation:
All angles of a right triangle equal 180°.
So you have to do a substitution method to find the value of x.
Which leaves us with: angle 'A' = 5 × 11.75, angle 'B' = ((3 × 11.75) -4), and angle 'C' = 90. If you add all of them together it is equivalent to 180°.
∴ x = 11.75
The ratio of Warrior fans to Laker fans at a basketball game was 5 to 3. If
there were 21 Laker fans, how many Warrior fans are there
Answer:
35
Step-by-step explanation:
Create a proportion where x is the number of Warrior fans
[tex]\frac{5}{3}[/tex] = [tex]\frac{x}{21}[/tex]
Cross multiply and solve for x
105 = 3x
35 = x
So, there were 35 Warrior fans
Answer:
[tex] \bf\huge warrior \: fans = 35[/tex]
Step-by-step explanation:
Given that :The ratio of Warrior fans to Laker fans at a basketball game was 5 to 3.If there were 21 Laker fans.to find :how many Warrior fans are there.let us assume :warrior fans is X .explanation :finding the warrior fans
⟼ warrior : laker fans = 5 : 3 = x : 21
⟼ 5 : 3 = x : 21
⟼ [tex]\frac{5}{3} \times \frac{x}{21} [/tex]
⟼ x = 5 × 7
⟼ x = 35.
⟼ warriors fans = 35.
∴ laker fans is 21 and warriors fan is 35.
∴ warriors : laker fans = 5 : 3 = 35:21.

If there was only one government class, and Wes and Maureen were in that class of 38 students, what would be the probability that both Wes and Maureen would be selected as the two students to go to Washington? Is this still an example of independent events
The probability of an event is 1/19. Therefore, the given situation is not an independent event.
Given that, Wes and Maureen were in the government class of 38 students.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes
Total number of outcomes =38
Number of favourable outcomes = 2
So, probability =2/38
= 1/19
Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event.

At the start of a hike, a hiker was at an elevation of -50 feet (where 0 represents sea level). The hiker climbs at a rate of 15 feet per minute. a. Write an inequality that represents t, the number of minutes after the start of the hike, when the hiker’s elevation was higher than 5 feet above sea level.
Answer:
15t - 50 > 5Step-by-step explanation:
Initial point = -50 ftClimbing rate = 15 ft / minTime = tRequired inequality:
15t - 50 > 5Solution:
15t > 55t > 55/15t > 3 10/15 = 3 40/60 min = 3 min 40 secondsAnswer:
Solution given:
Initial point = -50 ft
Climbing rate = 15 ft/min
Time = t(let)
So Required inequality:
15t-50 > 5
adding 50 on both term
15t> 55
dividing both term by 15
t > 55/15

In the interval 0° < x < 360°, find the values of x for which sin x = 0.6691 Give your answer tot he nearest degree
Answer:
x are 42 and 138degees
Step-by-step explanation:
Given the expression sin x = 0.6691
sin x = 0.6691
Take the sin inverse of both sides
sin⁻¹(sin x) = sin⁻¹(0.6691 )
x = sin⁻¹(0.6691 )
x = 41.99
x = 42 degrees (to the nearest degree)
Since sin theta is positive in the second quadrant;
x = 180 -theta
x = 180 - 42
x = 138degrees
Hence the value of x are 42 and 138degees

You 5-year loan of $14,000 is at 4.3% compounded annually. How much will you have paid in total for your loan?
Answer:
$17,276
Step-by-step explanation:
Given data
Time= 5 years
Principal= $14,000
Rate= 4.3%
We want to find the final amount
A=P(1+r)^t
Substitute
A= 14000(1+0.043)^5
A= 14000(1.043)^5
A= 14000*1.234
A=$17276
Hence the total amount is $17,276
Un alumno multiplica un número por 32 en lugar de multiplicarlo por 23, obteniendo un producto mayor en 54 al producto original. Halla la suma de cifras del producto original
Answer:
La suma de cifras del producto original es igual a 12.
Step-by-step explanation:
De acuerdo a la información proporcionada, si multiplicas un número "x" por 32 su resultado sería igual al producto original "y" más 54 dado que dice que se obtiene un producto mayor en 54 al producto original, lo que se puede expresar de la siguiente forma:
32x=y+54
Además, se puede inferir a partir del enunciado que si el número x se hubiera multiplicado por 23 el resultado habría sido el producto original que lo denominamos como "y", por lo que puedes decir que:
y=23x
Ahora puedes reemplazar y=23x en 32x=y+54 y despejar x:
32x=23x+54
32x-23x=54
9x=54
x=54/9
x=6
Finalmente, puedes reemplazar el valor de x en y=23x:
y=23x
y=23*6
y=138

Six friends attend a music concert and spend $27 per ticket. They each purchase a souvenir t-shirt. If the friends spend a total of $231, how much does each souvenir t-shirt cost
Answer:
11.50
Step-by-step explanation:
6x27=162
231+-162=69
69 divided by 6 is 11.5
11.5=11.50
11.50 is your answer
Answer:
$11.50.
Step-by-step explanation:
If there are 6 friends, and every ticket costs $27, then we need to multiply.
6 x 27 = 162.
Then, we subtract the cost of the tickets so we can find the total cost of the souvenir t-shirts.
231 - 162 = 69.
Since each of the 6 friends bought a souvenir t-shirt, we divide the total cost by the number of people.
[tex]\frac{69}{6}[/tex] = 11.5.
So, each t-shirt costs $11.50.

Answer:
37.3032cm^2
Step-by-step explanation:
Given data
Diameter= 0.6cm
Radius= 0.3cm
Lenght = 19.5cm
Surface area (A) =2πrh+2πr^2
Substitute
A=2*3.14*0.3*19.5+2*3.14*0.3^2
A=36.738+0.5652
A=37.3032
Hence the surface area is
