Answer:

(a) 39

(b) 63

Step-by-step explanation:

(a) 4^3-5^2

In this kind of equation, ensure that the square on each of the figures is well treated

Deal with the square first before dealing with the given equation

Here it's goes

4^3 means cube of 4 which means 64

5^2 means square of 5 which is 25

Back to the question

4^3-5^2

64-25

=39

Therefore the final answer is 39

(b)6^2+3^3

Which means 6^2 square of 6 and it equals to 36

3^3 means cube of 3 which equals to 27

Back to the question

6^2+3^3

36+27

=63

Therefore the final answer is 63

Job natural peanut butter normally cost four dollars today it’s on sale for $3.60 what is the percentage of the discount
Rzqust [24]
We can make an equation that would help this. X will be the discount rate.
4x=3.60
Now, we need to solve the equation to find what X is.
Let's divide each side by 4.
x=.9
So, we know that the item was sold for 90% of what it was before, meaning that it has a 10% discount.

Lesechka [4]

Answer:

2x -3y =1 and 3x-2y= 4 has

Step-by-step explanation:

The pair of linear equations 2x-3y=1 and 3x-2y=4 has one unique solution. , then it has a unique solution other wise not. Since , , it means the pair of linear equations has only one unique solution. Hence, the pair of linear equations 2x-3y=1 and 3x-2y=4 has only one unique solution.

a1/a2= 2/3

b1/b2= 3/-2 (-) cancle so it remains

c1 / c2 = 1/4

a1/a2 = b1/b2 not equal to c1/c2 as no solution

6. A hospital needs a supply of an expensive medicine. Company A has the most
Anton [14]

We are required to find the total milligrams if medicine the hospital can get from the three companies.

The total quantity of medicine the hospital can get from the three companies is 2.75 milligrams

There are there companies:

Company A

Company B

Company C

Company A = 1.3 milligrams

Company A is 0.9 milligrams more than Company C's

A = 0.9 + C

1.3 = 0.9 + C

1.3 - 0.9 = C

0.4 = C

C = 0.4 milligrams

Company A is also twice the difference between the weight of

Company B's supply and Company C's

A = 2(B - C)

1.3 = 2(B - 0.4)

1.3 = 2B - 0.8

1.3 + 0.8 = 2B

2.1 = 2B

Divide both sides by 2

B = 2.1/2

B = 1.05 milligrams

Therefore,

A + B + C

= 1.3 + 1.05 + 0.4

= 2.75 milligrams
