Answer:
1,120 square feet
Step-by-step explanation:
Area of a rectangle = length × width
Length = 32 feet
Width = 35 feet
Area of a rectangle = length × width
= 32 feet × 35 feet
= 1,120 square feet
Therefore,
Area of the rectangular living room = 1,120 square feet

A baseball is thrown straight up in the air with an
initial velocity of 128 feet per second from a point
exactly 4 feet off the ground.
Write the function for the height of this object at any
time (t seconds)
Answer:
Step-by-step explanation:
[tex]h(t)=-16t^2+v_0t+h_0[/tex] where
h(t) is the height of the ball after a certain amount of time has gone by,
-16t² is the pull of gravity in ft/s/s,
v₀t is the initial upwards velocity, and
h₀ is the height from which the ball was initially thrown. Our equation is then, filling in the info in the correct places:
[tex]h(t)=-16t^2+128t+4[/tex] where 128 is the given initial velocity and 4 is the number of feet from which the ball was initially launched.

Please I need help The original price of a car was reduced by $3000. Its discount price is now 16000
Answer:
$19,000
Step-by-step explanation:
The original or initial price of the car = discount price + amount by which the car was reduced
$16,000 + $3000 = $19,000
The percentage decrease in price = (amount discounted / original price) x 100
( $3000 / $19,000) x 100 = 15.79%

Polly is comparing the cost of cell phone services. The phone she wants costs $899 at BT&T Cellular, and the unlimited calling plan through their carrier would cost $2 per day. At Revizon Electronics, Polly could purchase the same phone for $799 and also get an unlimited calling plan for $3 per day. After some number of days, the two options would end up having the same total cost. What would the total cost be? How long would that take?
Answer:
The total cost = $1,099
It would take 100 days
Step-by-step explanation:
Let
x = number of days
Cost of BT&T Cellular = 899 + 2x
Cost of Revizon Electronics = 799 + 3x
Equate the cost of both cell phone services.
899 + 2x = 799 + 3x
899 - 799 = 3x - 2x
100 = x
x = number of days = 100 days
Cost of BT&T Cellular = 899 + 2x
= 899 + 2(100)
= 899 + 200
= $1,099
Cost of Revizon Electronics = 799 + 3x
= 799 + 3(100)
= 799 + 300
= $1,099

y= 3x - 13
3x + 2y = 19
Answer:
x = 5 y = 2
Step-by-step explanation:
3x + 2(3x - 13) = 19
3x + 6x - 26 = 19
9x = 45
x = 5
y = 3(5) - 13
y = 15 - 13
y = 2
In a two-digit number, the units digit is twice the tens digit. If the number is doubled
it will be 9 more than the number reversed. Find the number.
T=Tens
U=Unit
From the question... The Unit digit is twice the Tens digit
Let the Number be xy
Meaning
y is the unit number
x is the tenth Number
Can be inferred for the question that
y=2x ...........(i)
Also
If the Number is doubled x2(times 2)
"It'll be 9more than the reversed"
Now listen
if you want to express a 2digit Number...
Let's say 45...
It can be expressed as 10x4 + 5 = 45
or
66 can be expressed as 10x6 + 6 = 66
So
It'd be better if we express this our unknown number like that too
So
Let's express "xy" like "10x + y"
Hope you grab?
Now from the second statement of the question..
If The Number is doubled...It'll be 9 more than the reversed
What is the reverse of that Number??
The reverse would be "10y + x"
You can see that x and y switched places.
so
The statement said...
2(10x + y) + 9 = 10y + x (reversed)
20x + 2y + 9 =10y + x ........(ii)
Recall from our first eqn
y=2x
Now substitute y=2x into eqn ii
20x + 2(2x) + 9 = 10(2x) + x
20x + 4x +9 = 20x + x
20x - 20x + 4x - x = -9
3x = -9
x=-3
y=2x
y=2(-3)
y=-6
So The Number is 10x + y
= 10(-3) + (-6)
=-30-6
=-36
This answer obeyed the first part of the question because the unit is twice digit(2x3)
Let's check if it obeyed the second part
2[(10(-3) + (-6)] + 9 = 10(-6) + (-3)
2(-30-6) + 9 = -60-3
-63=-63
The 2nd part is also true.
So
Our Number is -36.
I'm Open to corrections if you spot any.
20. The tens and units digit of the number are the same. When the number is
added to its reverse, the sum is 110. What is the number?
Answer:
55
Step-by-step explanation:
55 has both its tens and units the same and when you reverse it, it is still 55 hence 55+55 is 110
Given : The tens and units digit of the number are the same
Let the given number be : NN
Given : When the number is added to its reverse, the sum is 110
As the tens and units digit of the number are same, the reversed number is also : NN
⇒ NN + NN = 110
⇒ 2NN = 110
⇒ NN = 55
Answer: The Number is 55

Let x = -3 f(-3) = 2*-3 +4 = -6+4 = -2
Let x = -2 f(-2) = 2*-2 +4 = -4+4 = 0
Let x = -1 f(1) = 2*1 +4 = 1+4 = 6
Let x = 3 f(3) = 2*3 +4 = 6+4 = 10
Let x = 4 f(4) = 2*4 +4 = 8+4 = 12

Given tan A=-√5 and cos A >0, find sin A.
PLEASE HURRY AND SHOW WORK
Answer:
sinA = - [tex]\frac{\sqrt{5} }{\sqrt{6} }[/tex]
Step-by-step explanation:
Given
tanA = - [tex]\frac{\sqrt{5} }{1}[/tex] = [tex]\frac{opposite}{adjacent}[/tex]
This is a right triangle with opposite = [tex]\sqrt{5}[/tex], adjacent = 1 and
hypotenuse h² = ([tex]\sqrt{5}[/tex] )² + 1² = 5 + 1 = 6 ⇒ h = [tex]\sqrt{6}[/tex]
Since tanA < 0 and cosA > 0 then A is in the 4th quadrant where sinA < 0
Then
sinA = - [tex]\frac{opposite}{hypotenuse}[/tex] = - [tex]\frac{\sqrt{5} }{\sqrt{6} }[/tex]

Answer:
170°
Step-by-step explanation:
The total degrees of a circle is 360°. So the math is pretty straight forward.
130 + 60 = 190 (First you find what the known degrees are together)
360 - 190 = 170 (Next you take that added total and subtract it from 360)
x = 170 (And there you go! Your answer!)

What is the length of the arc of a circle with radius 12 and central angle 3pi/4
Answer:
9 pi
Step-by-step explanation:
If the radius is 12, then the diameter would be 24 and the entire circle would be 24 pi.
24 times 3/8= 9
I used 3/8 because the unit circle has a circumference of 2pi so I divided it by 2.
De 1.620 trabajadores de una empresa textil 7/9 trabajan en confeccion y el resto en tareas administrativas. ¿cuantos trabajadores trabajan en confeccion?
Answer:
The number of employees work in clothing is 1260.
Step-by-step explanation:
Out of 1,620 workers in a 7/9 textile company work in clothing and the rest in administrative tasks. How many workers work in clothing?
Total workers = 1620
employees works for clothing = 7/9
So, the number of employees = 7/9 x 1620 = 1260
Usando la informacion dada, veremos que el número de trabajadores que trabajan en confección es 1,260.
Sabemos que hay un total de 1,620 trabajadores en la empesa textil.
7/9 de ellos trabajan en confección.
Queremos ver el número de trabajadores que trabaja en confección, para ello, simplemente debemos multiplicar la fracción del número total que trabaja en confección por el número total, es decir:
N = (7/9)*1,620 = 1,260
1,260 trabajadores trabajan en confección.

Como sacar la circunferencia ?
Answer: Así que harás radio multiplicado por 2 y luego diámetro multiplicado por pi, que es 3,14, así que básicamente diámetro multiplicado por pi
Step-by-step explanation:
Answer:
La circunferencia de un círculo es la distancia alrededor del círculo. Se podría llamar perímetro del círculo.
Como encontrar la circunferencia de un círculo:
La circunferencia de un círculo se puede averiguar multiplicando pi ( p= 3.14) por el díametro del círculo.
Si un círculo tiene un diámetro de 4, su circuferencia es 3.14*4=12.56
Si conoces el radio, el diámetro es dos veces su largo.
