First lets simplify the first term and yield (2a)

The second term:
1.   2a * (-1/2) = -a
2.   -a + a = 0

Now we have simplified both terms to: (2a) (0)

Anything multiplied by 0 is 0, so the answer is also 0.

A(2)*(2a(-1/2)+a)
= (2a)*(-1*a+a)
=(2a)*(-a+a)
=(2a)*0
=0

So 0 is the final answer.

Hope this would help :))

Hakim saves money for one year to buy a computer.
elena55 [62]

Answer:

$111

Step-by-step explanation:

First we need to take a look at the bank account of Hakim. Hakim initially invested $700 in the bank with a 5% simple interest annually. Since Hakim waited for an entire year before buying the computer, he will then have the extra 5% interest from the bank.

Let's first compute for how much Hakim will have in total in the bank.

A = P(1 + rt)

P = 700 Initial Investment

r = 5% or 0.05 Interest

t = 1 Year

A = 700(1 + (0.05 x 1))

A = 700(1 + 0.05)

A = 700(1.05)

A = 735

So now we know that Hakim has a total of $735 in his bank account.

Now let's move on to calculating the total cost of the computer. We know that the sales tax is always computed after the discounted price.

So first we find the discounted price.

x = 750

d = 20% or 0.20

Discount = 750 x 0.20

Discount = 150

Now that we have the discount of the computer, we then simply subtract the discount to the initial price.

750 - 150 = 600.

The computer will then cost $600 with the discounted price.

Now we have to find the sales tax.

Sales Tax = 4% or 0.04

Total Discounted Price = 600

600 x 0.04 = $24

Now that we have the sales tax, we simply add the sales tax to the discounted price.

600 + 24 = 624.

Now that we know how much the total cost of the computer is with the discount and sales tax, we simply subtract the total cost of the computer to Hakim's current account balance.

735 - 624 = 111

Hakim will have a total of $111 in his bank account after purchasing the computer.

Which graph correctly represents 1/3y-1/2x>2 ?
Tanzania [10]
<span>Put it in the form of y =mx +b, or in this instance, y> mx +b 
move the (1/2) x to the right by adding it to both sides of the inequality 
(1/3)y>(1/2)x +2 
Multiply by 3 on both sides to get y by itself. 
y>(3/2) x +6 
This is a graph with y intercept of (0,6) and a moderate upward and to the right slope. Because it is > , the line on the graph will NOT be part of the solution. 

The easiest way to find the side of the graph that the inequality satisfies is to use (0,0) and see if it works or doesn't work. In the original equation, 0-0>2 does NOT work, so the area where the inequality works is to the up and left of the graph, which should be a dotted line to show that the inequality is greater than only. 
The point (6,-2) should work.
Test it. 6*(1/3)-(-2)*(1/2)>0 ; 2-(-1)=3, and 3>2 It does work. 
The point (6,2) should not work 
Test it. 6 *(1/3)-2(1/2)=2-1 ; 1 is NOT >2, so it does not work. 
If the graph goes through the origin, then pick a point near the graph with a small x or y.</span>

The total surface area of a cube is 294cm2. work out the volume of the cube.
Mamont248 [21]

Answer: 343 cm³

Step-by-step explanation:

The surface area of a cube is 6s^2, where s is the side length of a square.  Thus, first do 294/6 to get 49.  Then take the square root of 49 to get that each side of the cube is 7.  The volume of a cube is s^2, so simply do 7*7*7 to get that the volume of the cube is 343cm^3

i need help with math my question is i hope this question doesnt get deleted so my question is which of the following numbers is
DENIUS [597]
Any number that ends with 0 or 5 is divisible by 5. If it ends with any other numbers such as 1 2, 3, 4, ,6, 7, 8, 9 then it is not divisible by 5. If a number is divisible by it means that the number can be divided by 5.

5, 10, 15, 20, 25, 1234567890, 9876543210, etc. are going to be divisible by 5 because they end or a 0.

So, look through your given options. Which answer choice has a 0 or a 5 at the end of the number? That's your answer. :)

Hope that helped. (:
