Write an equation to represent the real world problem below.
The area of a rectangle measures 9/14 ft^2. It has a length of 3/7 of a foot and a width of 1 1/2 feet.
The equation which represents the real world problem involving a rectangle as described in the task content is; 9/14 = 3/7 × 3/2.
What is the equation which represents the real world problem as given in the task content?It follows from the task content that the equation which represents the real world problem involving a rectangle be determined.
It follows from plane shape measures that the area of a rectangle is;
Area = length × width.
Hence, from the parameters given; we have;
Area = 3/7 × 1 1/2
Area = 3/7 × 3/2
Ultimately, the model according to the given parameters which hold true is;
9/14 = 3/7 × 3/2.

Answer:
3 18/19
Step-by-step explanation:
1. Change to improper fractions.
(You do this by multiplying the denominator and the whole number, then add the numerator.)
7 1/2 ⇒ 15/2
1 9/10 ⇒ 19/10
So now its: 15/2 ÷ 19/10
2. Keep, change, flip
Keep the first number (15/2), change the division to multiplication, flip the other fraction (From 19/10 to 10/19).
3. Multiply
15/2 × 10/19 = 150/38
Simplified, the answer is 3 18/19

You draw one card from a 52 card deck. Then the card is replaced in the deck and the deck is shuffled, and your draw again. Find the probability of drawing a five each time.
Answer:
1/169Step-by-step explanation:
There are 4 five's in the deck.
Probability of drawing a five is:
P (5) = 4/52 = 1/13Since the card is replaced, it has same probability the second time.
So the probability of drawing a five twice is:
P(5, 5) = 1/13*1/13 = 1/169Which expression is equivalent to
A:4x
B:4x+4
C:x^2+7x+10
D:-x^2-5x-6
The expression equivalent to [tex](x+2)+[4x-(\frac{x^{2}+6x+8 }{x+4})][/tex] is option (A) 4x.
As per the question statement, we are given with an expression [tex](x+2)+[4x-(\frac{x^{2}+6x+8 }{x+4})][/tex].
We are required to simplify the above mentioned expression.
To solve this question, let us simplify the expression, part by part.
First, We are considering the part (x² + 6x + 8), which can be rewritten as
[tex][( (x^{2} + 6x + 9) - 1][/tex]...(1)
Now, [tex](x^{2} +6x +9)=[(x)^{2} +(2*x*3)+(3)^{2}][/tex]...(2)
Comparing [tex][(x)^{2} +(2*x*3)+(3)^{2}][/tex] with the standard form of
[(a + b)² = (a² + 2ab + b²)], we get, (a = x) and (b = 3).
Therefore, [tex][(x^{2} +6x +9)=(x+3)^{2}][/tex], then,
[tex][( (x^{2} + 6x + 9) - 1] = [(x+3)^{2} -1]\\or, (x^{2} + 6x + 8)=[(x+3)^{2}-(1)^{2}][/tex]...(3)
Again, comparing [tex][(x+3)^{2}-(1)^{2}][/tex] with the standard expansion of
[(c²- d²) = (c + d)(c -d)], we get, [(x + 30 = c] and (d = 1).
Therefore, [tex][(x+3)^{2}-(1)^{2}]=[(x+3+1)(x+3-1)][/tex]
[tex]or, (x^{2} + 6x + 8) = (x+4)(x+2)[/tex].
Using the simplified value of (x² + 6x + 8) in the expression [tex](x+2)+[4x-(\frac{x^{2}+6x+8 }{x+4})][/tex], we get,
[tex](x+2)+[4x-(\frac{x^{2}+6x+8 }{x+4})]=(x+2)+[4x-\frac{(x+4)(x+2)}{(x+4)} ]\\or, (x+2)+[4x-(\frac{x^{2}+6x+8 }{x+4})]=(x+2)+[4x-(x+2)]\\or, (x+2)+[4x-(\frac{x^{2}+6x+8 }{x+4})]=(x+2)+[(4x-x)-2]\\or, (x+2)+[4x-(\frac{x^{2}+6x+8 }{x+4})]=(x+2)+(3x-2)\\or, (x+2)+[4x-(\frac{x^{2}+6x+8 }{x+4})]=[(x+3x)+(2-2)]\\or, (x+2)+[4x-(\frac{x^{2}+6x+8 }{x+4})]=4x[/tex]

What is x and what is y
The value of x is 3.6 and the value of y is 13.35.
We are given the equations that:
15 x - 26 = 28°
12 x + 1 = (4 y - 9)°
Now,
15 x - 26 = 28°
Add 26 to both the sides:
15 x = 28 + 26
15 x = 54
Divide both sides by 15, we get that:
x = 54 / 15
x = 3.6
Now, we have:
12 x + 1 = (4 y - 9)°
Substitute x = 3.6
12 (3.6) + 1 = 4 y - 9
43.2 + 1 = 4 y - 9
44.2 = 4 y - 9
4 y = 44.2 + 9
4 y = 53.2
y = 53.2 / 4

The speed of her plane in feet per second is 50 feet per second and the plane high was 1750 feet.
i. The speed of Hailey’s plane is 50 feet per second.
As Hailey’s plane took 90 seconds to climb 4,500 feet,

X= 50 feet per second.
ii. The plane was at 1750 feet at 35 seconds.
As the plane climb 50 feet per second,
X= 50 * 35
X= 1750 feet.
Jetliners typically fly between 240 and 285 km/h during take-off (130–154 km; 149–177 mph). Light aircraft, such a Cessna 150, accelerate to about 100 km/h after take-off (54 km; 62 mph). Even slower take-off speeds apply to ultra-lights.

How much pure acid should be mixed with 5 gallons of a 70% acid solution in order to get a 90% solution?
Answer:
You will need 10 gallons of pure acid to mix with 5 gallons of a 70% acid solution to get a 90% solution.
Step-by-step explanation:
.70(5) + x = .90(x + 5) I want to multiply both sides by 100 to clear the decimal
70(5) + 100x = 90(x + 5) Distribute the 70 and the 90
350 + 100x = 90x + 450 Subtract 90x from both sides
350 + 10x = 450 Subtract 350 from both sides
10x = 100 Divide both sides by 10

La rueda recorre una distancia de 75.420 metros tras 60 vueltas. (Correct choice: A)
Cuánta distancia recorre una rueda que da 60 vueltas?
La rueda se desplaza sobre el suelo mediante un tipo de movimiento conocido como rodadura, en la que la rueda experimenta rotación y traslación, cuyo centro instantáneo de rotación es el punto de contacto entre la rueda y el suelo.
Si no existe deslizamiento de la rueda con respecto al suelo, entonces la distancia recorrida tras una revolución de la rueda (s), en metros, es descrita por la siguiente ecuación:
s = 2π · r (1)
Donde r es el radio de la rueda, en metros.
Si tenemos que r = 0.20 m, entonces la distancia recorrida es:
s = 2π · (0.20 m)
s ≈ 1.257 m
Asimismo, la distancia recorrida es directamente proporcional al número de revoluciones de la rueda es y la distancia recorrida tras 60 vueltas es determinada por regla de tres simple:
S = 60 vueltas × (1.257 m / 1 vuelta)
