Un cuerpo de 180 kg se debe lanzar hacia una distancia de 25 m. ¿Qué valor tiene el trabajo que se realiza al lanzarlo?
Answer:
45, 000 J o 45 KJ
Step-by-step explanation:
Recordemos que trabajo realizado = fuerza * distancia
En este caso, fuerza = peso del objeto
Por lo tanto, peso del objeto = 180 Kg * 10ms ^ 2 = 1800 N
Por eso;
Trabajo realizado = 1800 N * 25 m = 45, 000 J o 45 KJ

Answer: 9.7
Step-by-step explanation: I got this question right
70+30 = 100
B = 180 - 100 - 20
B = 60°
80+20 = 100
C = 180 - 100 - 30
C = 50
DB/sin100 = 8/sin(60)
8*sin(100)/sin(60)
DB = 9.0973
DC/sin(30) = 8/sin(50)
8*sin(30)/sin(50)
DC = 5.22163
x = [tex]\sqrt{5.22163^{2} +9.0973^{2} -2*5.22163*9.0973*cos(80)[/tex]
x = 9.7

A store was trying to sell a bed set for 475$. After a while, they marked the price tag down 35%. If tax is 5% (of the sale price) how much would the bed cost
Answer:
$324.19
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Price = $475
Price tag down = 35%
Tax = 5%
So, price after tag down = $475 - ( $475 × 35%)
= $475 - $166.25 = $308.75
Now, we calculate tax value after price tag down,
Tax value = $308.75 × 5% = $15.44
So, we can calculate the bed cost by using following formula,
Bed cost = Price after tag down + Tax value
= $308.75 + 15.44
= $324.19
A 170 ft string attached to a kite makes a 40⁰ angle with the ground. What is the height of the kite to the nearest tenth? 130.2 ft 33 ft 142.6 ft 109.3 ft
Answer:
109.3 ft
Step-by-step explanation:
Remembering SOHCAHTOA
We would be using sin
sin = opposite / hypotenuse
sin 40 = x / 170
0.6428 = x/170
x = 0.6428 x 170 = 109.3 ft

Which equation is equivalent to 23x= 10?

log, 3x = 10
log 2 = 30
log 3.0

After applying some properties of logarithm the correct expression for the given logarithmic equation we get is 3x = log₂ 10.
Use the concept of logarithm defined as:
The logarithmic function is the opposite of the exponentiation of that function.
It can be mathematically defined as:
For [tex]x > 0 , a > 0[/tex], and [tex]a\neq1[/tex],
[tex]y= log_a x[/tex] if and only if x = ay
Then the function is given by
[tex]f(x) = log_a x[/tex]
Where a is the base of function.
The given expression is:
[tex]2^{3x} = 10[/tex]
Take log both sides,
[tex]\text{log } 2^{3x} = \text{log } 10[/tex]
Since we know that,
[tex]\text{ log} a^n = n\text{ log} a[/tex]
Therefore,
3x log 2 = log 10
Dividing both sides by 2
3x = log10/log2
Since we know that,
[tex]\text{log} _a b = \dfrac{\text{log}_c b}{\text{log}_c a}[/tex]
Therefore,
3x = log₂ 10.
Hence,
The correct expression is 3x = log₂ 10.

Part II: Using the variable you defined in Part I, write an expression to represent the
amount of money Sam will spend in one year (Sam's cost). (2 points)
Answer:
Number of wooden carving = a
Total amount Sam spend = 1,200 + 4a
Total revenue of Sam = 15a
Number of wooden carving make to earn profit $4,300 = 500 carvings
Step-by-step explanation:
Given:
Sales price of each wooden carving = $15
Fixed cost = $1,200
Variable cost = $4 for each
Find:
Number of wooden carving make to earn profit $4,300
Computation:
Part 1
Assume
Number of wooden carving = a
Part 2
Total amount Sam spend = 1,200 + 4a
Part 3
Total revenue of Sam = 15a
Part 4
Total profit of Sam = Total revenue of Sam - Total cost of Sam
4,300 = 15a - [1,200 + 4a]
4,300 = 15a - 1,200 - 4a
11a = 5,500
a = 5,500 / 11
Number of wooden carving make to earn profit $4,300 = 500 carvings

The sum of two numbers is 3, and twice the larger number is 36 more than three times the smaller number. Find the numbers.
Please use system of linear equations by elimination OR substitution. Please show the work as well.
Answer:
x = -6
y = 9
Step-by-step explanation:
The sum of two numbers is 3
x + y = 3
twice the larger number is 36 more than three times the smaller number
2y = 3x + 36
Divide both sides by 2
y = 1.5x + 18
substitute for y in the first equation
x + (1.5x + 18) = 3
2.5x = -15
divide both sides by 2.5
x = -6
Substitute for x in the first equation
-6 + y = 3
y = 9
The sum of two numbers is 3, and twice the larger number is 36 more than three times the smaller number. The number are x = -6 and y = 9.
What is linear equation?A linear equation is an equation in which each term has at max one degree.
Linear equation in variable x and y can be written in the form y = mx + c
Linear equation with two variables, when graphed on a cartesian plane
with axes of those variables, give a straight line.
It is given that the sum of two numbers is 3.
x + y = 3
Also, twice the larger number is 36 more than three times the smaller number, then
2y = 3x + 36
Divide both sides by 2
y = 1.5x + 18
By substituting for y in the first equation
x + (1.5x + 18) = 3
2.5x = -15
now, divide both sides by 2.5
x = -6
Substitute for x in the first equation
-6 + y = 3
y = 9

A number is chosen at random from 6 to 25. Find the probability of selecting an even number or multiple of 3.
Answer:
17/25
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
even numbers between 6 and 25 = 6 8 10 12 14 16 18 20 22 24
multiples of 3 = 6 9 12 15 18 21 24

How to find area of a composite figure?The figure above is a composite figure as it has both rectangle and a semi circle.
The area of the figure(sitting room) is as follows:
total area = area of rectangle + area of semi circle
area of rectangle = lw
where
l = lengthw = widthTherefore,
l = 15 ft
w = 14 ft
area of rectangle = 15 × 14 = 210 ft²
Area of semi circle = πr² / 2
Area of semi circle = 3.14 × 7² / 2
Area of semi circle = 3.14 × 49 / 2
Area of semi circle = 153.86 / 2
Area of semi circle = 76.93 ft²
