If 3/2 ÷ 1/4 = n, then n is between: A. 1 and 3 B. 3 and 5 C. 5 and 7 D. 7 and 9

1 answer:

8 0

3/2 ÷ 1/4 is 3/2 x 4/1 (the reciprocal)
Since 3/2 is the same as 1 1/2 we are asking how much are 4 x 1 1/2
Think money
1 1/2 is like $1.50
If I had $1.50 two times - I'd have $3.00
If I had $1.50 four times - I'd have twice as much or $6.00

Now I know that 6 is between 5 and 7 so answer c. is correct
You could also just multiply 3/2 x 4/1 but I think my explanation helps you understand it better than just using the multiplication algorithm.

How many different pizzas combinations can be created using three toppings when you have 10 to choose

Sergeeva-Olga [200]

Answer:

120 different combinations

Step-by-step explanation:

How complicate do you want it be? consider or not consider the repeat of topping or the order of toppings.

If not consider the order of topping and the topping can't be repeated than

C(₁₀ , ₃) = (10 x 9 x 8) / (3 x 2 x 1) = 120

What is the answer for 4x + 2y = 12

sesenic [268]

Answer:

(1,4), (2,2) (3,0)

Step-by-step explanation:

adjust the equation so that the y is isolated so subtract 4 x

2y=4x +12

Every number is divisible by 2 so you can further isolate the y

y=-2x+6

Plug your x coordinates into the equation so get the y coordinates

1. a type of bamboo holds a Guinness world record for the fastest growing plant.is can grow 91cm a day. how fast in inches per h

nikdorinn [45]

Given length is 91 cm

1 cm = 0.3937 inch

so, 91 cm = 91* 0.3937 = 35.826 inches

1 day = 24 hours

In 24 hours the bamboo grows = 35.826 inches

In one hour it will grow = $\frac{35.826}{24}$

= 1.492 inches per hour. Hence the bamboo grows 1.492 inches per hour.

We have to convert hours and seconds in minutes.

1 hour = 60 minutes

so 10 hours = 60 * 10 = 600 minutes.

60 seconds = 1 minute

so 24 seconds = $\frac{24}{60}$ = 0.4 minutes.

Now we have been given the total time as 10 hours, 39 minutes and 24 seconds

So adding all values in minutes, we get

600 + 39 + 0.4 = 639.4 minutes

So Saturn takes 639.4 minutes to complete one rotation

Given equation is 0.4(30h)+30h

0.4(30h) represents the amount of tax Kimberly has to pay.
