You can use the circumference of the circle that the blade makes to calculate the linear velocity at the end of the blade.
The linear velocity at the end of the blade is 13571.7 inches per minute
How to find the linear velocity of the lawnmower blade?You can think of it as if some circle is being drawn by the end of the blade and then that circle is like wheel of a bicycle and its travelling on road. Each rotation will make it cover distance equal to its circumference. Since there are 60 revolutions of the blade in each minute, thus, 60 rounds of that wheel.
The total distance in 1 minute = 60 times circumference of the circle made by the end of the blade of the lawnmower.
Since the blade is 36 inches long, it can be taken as radius of that circle.
The circumference is thus calculated as [tex]2 \times \pi \times 36 = 226.19 \: \rm inches[/tex]
Thus, linear velocity = 226.19 times 60 inches per minute = 13571.7 inches per minute
Thus,
The linear velocity at the end of the blade is 13571.7 inches per minute

Step-by-step explanation:
3x + 2y = 8
5x + 2y = 12
Step-by-step explanation:
to solve simultaneously
subtract the 1st equation from the 2nd.
5x + 2y = 12
3x + 2y = 8
5x - 3x + 2y - 2y = 12 - 8
2x = 4
x = 4 / 2
x = 2.
Pablo made $357 for 17 hours of work.
At the same rate, how many hours would he have to work to make $168?
Answer:
8
Step-by-step explanation:
357÷17=21
168÷21=8
so $357 divided by the 17 hours is 21
then you do the $21 per hour multiplied by the money is what he makes then divide 21 and 168

In mathematics, the Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
so QT² = 25² - ST²
QT = 24
RT² = 51² -25²
RT = 45
RS = 45 - 7 = 38 cm

Answer:
300 ft³
Step-by-step explanation:
The easiest thing to do is to separate it into 3 cuboids. Then work out the volumes of each cuboid and add them together.
Volume of a cuboid = width x height x depth
The left cuboid has a width of 12 - 5 - 4 = 3 ft
From inspection, it has a height of 4 ft and a depth of 5ft.
So the volume of this is 3 x 4 x 5 = 60 ft³
The middle cuboid has a height of 6 + 2 = 8 ft
From inspection, it has a width of 5ft and a depth of 5ft
So the volume of this is 8 x 5 x 5 = 200 ft³
Finally, the right cuboid has a width of 4ft, a height of 2 ft and a depth of 5ft. So the volume is 4 x 2 x 5 = 40 ft³
Therefore, the total volume = 60 + 200 + 40 = 300 ft³

Hint: There are 16 cups in 1 gallon.
===============================================
Work Shown:
1 gallon = 16 cups
3 gallons = 48 cups ... multiply both sides by 3
(2 cups of milk)/(1 cake) = (48 cups of milk)/(x cakes)
2/1 = 48/x
2x = 1*48

7. Maria quiere cercar con malla un huerto de hortalizas de forma cuadrada cuya área es de 41 m?, ¿cuál es la medida aproximada que deben tener los lados de la superficie?
Considerando la definición de área, la medida aproximada que deben tener los lados de la superficie es 6.40 m.
Definición de áreaEl área es la medida de un espacio delimitado por un contorno al que se denomina perímetro. En otras palabras, el área es la medida de la región o superficie encerrada por de una figura geométrica.
El área en un polígono es la superficie que esta abarca, es decir, el área es todo el interior de la figura que está conformada por sus lados, pues el área es toda la superficie que encierran estos lados.
Área de un cuadradoEl cuadrado es un polígono de cuatro lados, con la particularidad de que todos ellos son iguales. Además sus cuatro ángulos son de 90 grados cada uno.
El área de esta figura se calcula a partir de uno de sus lados, lo que corresponde al producto de la base por la altura. Ya que todos los lados tienen la misma longitud, el área del cuadrado será:
Área= Lado× Lado= Lado²
Lado del huerto de hortalizasMaría quiere cercar con malla un huerto de hortalizas de forma cuadrada cuya área es de 41 m².
Para calcular los lados de la superficie, se debe reemplazar el valor de la superficie en la definición:
41 m²= Lado²
Resolviendo:
√41 m²= Lado
6.40 m≅ Lado
Finalmente, la medida aproximada que deben tener los lados de la superficie es 6.40 m.
