Work out 50 divided by [6-4]

1 answer:

8 0

This is pretty simple. This requires the order of operations. So for the order of operations, it basically tells you the order on how you solve operations.

The first order is brackets, the second one is division, the third one is multiplication and the fourth one is addition or subtraction.

For this case, you have { 6-4 }. 6-4 is on brackets, so you have to solve it first. The answer is 2.

After that, you can divide 50 by 2, which gives you 25.

I hope I have been helpful. Good luck! :)

$100000=P\left(1+\frac{0.066}{2}\right)^{2\cdot 20}\implies 100000=P(1.033)^{40} \\\\\\ \cfrac{100000}{1.033^{40}}=P\implies 27288.97\approx P$

vladimir1956 [14]

Answer:

7/40

Step-by-step explanation:

There are 3 girls+9 boys = 12 students in the 7th grade

P (girl in 7th grade) = girls/ total

= 3/12 = 1/4

There are 7 girls+3 boys = 10 students in the 8th grade

P (girl in 8th grade) = girls/ total

= 7/10

P(7th grade girl, 8th grade girl) = 1/4 * 7/10 = 7/40

A rectangle has a width of 3 units and a length of 4 units. Nancy needs to increase both the length and the width of the rectang

yarga [219]

Step-by-step explanation:

The length of a rectangle, l = 3 units

The breadth of a rectangle, b = 4 units

Nancy needs to increase both the length and the width of the rectangle by 2 units.

The area of a rectangle is given by

A = length(l) × breadth(b)

Here,

A = 3 × 4

= 12 unit²

If both length and width of the rectangle increase by 2 units,

New length = (4+2) = 6 units

New width = (3+2) = 5 units

New area = 6 × 5 = 30 unit²

Hence, new area becomes 30 unit².
