Write an equation for the hanger diagram and then us the sketch to show how to solve the equation algebraically.
Step-by-step explanation:
Since there are 3 w's and a 1 on one side and 7 1's on the other and the hanger diagram shows they are even, we can set them equal to each other.
3w + 1 = 7 Subtract 1 from both sides
3w = 6 Divide 3 from both sides
w = 2

Un comerciante compra 16 máquinas de coser a S/.408 cada una: 27 equipos de sonido a S/. 732 cada uno y 19 lavadoras a S/. 652 cada una. ¿Cuánto pagó por todo?
Answer:
Costo Total= $38,680
Step-by-step explanation:
Dada la siguiente información:
Un comerciante compra 16 máquinas de coser a S/.408 cada una: 27 equipos de sonido a S/. 732 cada uno y 19 lavadoras a S/. 652 cada una.
Para calcular el costo total, debemos usar la siguiente formula:
Costo Total= costo unitario * cantidad adquirida
Costo Total= 408*16 + 732*27 + 652*19
Costo Total= $38,680
The total amount of everything including sewing machines, sound systems, and washing machine is $38,680.
What is the cost price?The cost price refers to the original price of the items, it is the total amount of money that costs a manufacturer to provide a given product.
The unit cost of sewing machines = 408
The unit cost of a sound system = 732
The unit cost of a washing machine = 652
Total cost = 408 × 16 + 732 × 27 + 652 × 19
= 6528 + 19764 + 12388
= $38,680
Therefore, the total amount of everything including sewing machines, sound systems, and washing machine is $38,680.

Step-by-step explanation:
The volume of a cone is 1/3(B*h) where B is the base area and h is height.
The base of a cone is a circle.
Area of a circle=πr^2
Area of the circle=π6^2
Area of the circle=36π
Plug it into the formula for the volume:
V=1/3(36π*10)
V=1/3(360π)
V=120π
V=376.99
