Mrs.Davis bought 6 pounds of grapes for 18 dallors at this rate how much would 72 ounces of grapes have cost

harkovskaia [24]

Answer:

Cost of 72 ounces of grapes is $13.5

Step-by-step explanation:

In order to solve his problem, we first need to get all the values in the same units.

1 pound = 16 ounces

∴ 6 pounds= 16×6 = 96 ounces

Now by unitary method, we solve the question as follows:

price of 96 ounces of grapes = $ 18

price of 1 ounce of grapes = $ (18÷96)

∴ price of 72 ounces of grapes = $ [(18÷96)×72]

= (0.1875×72) = $ 13.5

marco has 37 1/2 ounces of juice he wants to pass out samples of the juice each cup can hold 2 1/2 ounces of juice how many cups

Crank

So 37 1/2
each can hold 2 1/2 oz

how many cups can he fill

37 1/2=75/2
2 1/2=5/2

x=number of cups
x times 5/2=75/2
5/2x=75/2
multiply both sides by 2
5x=75
divide both sides by 5
x=15
he can fill 15 cups

Pls help me figure this out

hodyreva [135]

Answer:

C. $\frac{27}{225}=\frac{b}{100}$

Step-by-step explanation:

To find the number of black ribbons one would have subtract the amount of red ribbons from the total number of ribbons. Then one would have to express it as a proportion. Part over whole equals percent over 100. The number of black ribbons over total ribbons equals "b" over 100.

1- El area de un cuadrado es igual a 8 veces la medida de su lado ¿ Cuánto mide por lado el cuadrado?

Papessa [141]

El área de un cuadrado es igual a 8 veces la medida de su lado. ¿Cuánto mide por lado el cuadrado ?

El Area de un Cuadrado es : A = L²

L² = 8 x L -------------> L² / L = 8 ----------> L = 8

Cada lado mide 8 unidades.

2) El triple del área de un cuadrado menos seis veces la medida de su lado es igual a cero ¿Cuánto mide por lado el cuadrado?

El Area de un Cuadrado es : A = L²

(3 x L²) - 6 L = 0

Factorizando : 3L ( L - 2 ) = 0 --------> L = 0 ; L = 2

Cada lado mide 2 unidades.
