Answer:
5. 50.3 m²
6. 113.1 cm²
7. 102.1 yards²
8. 50.3 yards²
9. 452.2 ft²
10.379.8 ft²
Step-by-step explanation:
Area of a circle = nr²
The circumference of a circle = 2nr
n = pi = 22/7
r = radius
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
radius = diameter / 2
5. (22/7) x 4² = 50.3 m²
6. (22/7) x 6² =113.1 cm²
7. radius = 11.4/2 = 5.7 yards
(22/7) x 5.7² =102.1 yards²
8. radius = 8/2 = 4 yards
(22/7) x 4² = 50.3 yards²
9. 2nr = 75.4 yards
2 x (22/7) x r = 75.4
to find r, divide both sides of the equation by 2 and 7/22
r = 12 ft
Area = (22/7) x 12² = 452.2 ft²
10. 2nr = 69.1 yards
2 x (22/7) x r = 69.1
to find r, divide both sides of the equation by 2 and 7/22
r = 10.99 ft²
Area = (22/7) x 10.99² = 379.8 ft²
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
L=30in
w Width

Answer:
La base salarial de cada trabajador es de $ 425
Step-by-step explanation:
Aquí queremos calcular la base salarial de cada trabajador
Antes del incremento, sea la base salarial $ x
Entonces, sin el incremento, lo que ganarán los 3 es x + x + x = 3x
Con el incremento, cada uno ganará 3 (x + 50)
Esto es lo que es igual a 1425 Así; 3 (x + 50) = 1425
x + 50 = 1425/3
x + 50 = 475
x = 475 - 50
x = 425
Y=-2/3x+-4. Here is the original equation for a line. (M is slope and b is y-intercept((the point which the line goes through the Y-axis))) y=Mx+b
