What is a equivalent fraction for 24/30
liq [111]
There's an infinite number of equivalent fractions for 24/30 - all you need to do is to divide or multiple both numerator and denominator by the same number. For example:

24/30 = 48/60 (because 24 * 2 = 48 and 30 * 2 = 60)
24/30 = 12/15 (because 24 ÷ 2 = 12 and 30 ÷ 2 = 15)
24/30 = 72/90 (because 24 * 3 = 72 and 30 * 3 = 90)
24/30 = 4/5 (because 24 ÷ 6 = 4 and 30 ÷ 6 = 5)
etc...

Change the order or grouping to find the sum. Explain how you used properties to find the sum. 63 + 86 + 77
notsponge [240]
You can't change the sum by changing the grouping. Any way you cut it, you will always get 226, as you only have addition operations, and the commutative property [a+(b+c)=(a+b)+c] means that the sum will always be the same.

HELP A FELLA OUT Please
Vanyuwa [196]

I'll write "x" instead theta.

sin x + 1 = cos(2x)

formula: cos(2x) = 1 - 2sin²x

sin x + 1 = 1 - 2sin²x

2sin²x + sin x = 0

sin x (2sin x + 1) = 0

sin x = 0 or sin x = -1/2

x1 = πk and x2 = -π/6 + 2πk and

x3 = 5π/6 + 2πk

for domain 0≤x<2π :

x1 = 0 (for k=0 in x1)

x2 = π (for k=1 in x1

x3 = 11π/6 (for k=1 in x2)

x4 = 5π/6 (for k=0 in x3).

k is an integral.

There are between 50 and 60 number of eggs in a basket. When Loza counts by 3's, there are 2 eggs left over. When she counts by
Strike441 [17]

Answer:

The number of eggs in the basket is 56

Step-by-step explanation:

Given as :

Let The number of eggs in the basket = 3x + 5x

When Loza counts 3's , there are 2 eggs left over

I.e , 3 ( x - 2 )

And  When Loza counts 5's , there are 4 eggs left over

I.e 5 ( x - 4 )

∴ 3 x - 6 = 5 x - 20

Or, 20 - 6 = 5 x - 3 x

Or,  14 = 2 x

∴     x = 7

So, the number of eggs = 3 × 7 + 5 × 7

                                        = 21 + 35 = 56

Hence The number of eggs in the basket is 56   Answer

A bedroom set lists for $7,000 and carries a trade discount of 20 percent. Freight (FOB shipping point) of $120 is not of the li
kirza4 [7]

Answer:

The total price is $5720

Step-by-step explanation:

According to the given statement a bedroom set lists for $7,000 and carries a trade discount of 20 percent. Freight (FOB shipping point) of $120 is not of the list price.

A bedroom lists for = $7000

Discount = 20% = 0.2

Now multiply 7000 by 0.2 = 7000* 0.2 = 1400

It means the discount value was $1400

Now subtract 1400 from 7000 = 7000 - 1400 = $5600

Now to get the total price add 5600 with 120 we get,

$5600+120 = $5720

Thus the total price is $5720 .....
