En said the value of the expression 72-8^2 +6*3 is 50. What mistake did Ben make? Correct Ben’s mistake and give the value of th
posledela

Given:

72-\frac{8}{2}+6\times3

He does mistake in the order of giving preference.

We should give preference in the order, division, multiplication, addition, subtraction.

But, he gave the first preferrence to the subtraction.

72-8=64

Next, he used division

64/2=32

Next he adds 32 with 8.

So, he gets 50.

But the actual simplification is,

Simplifying we get,

\begin{gathered} 72-\frac{8}{2}+6\times3=72-4+18 \\ =68+18 \\ =86 \end{gathered}

Hence, the correct value of the expression is 86.

Find the degree of the term -5x to the power of 4
marysya [2.9K]

Answer:

4 or -625x^4 (Just in case I misunderstood)

Step-by-step explanation:

The degree is always the power of something. Since -5x has a power of 4, its degree is 4.

Just in case I misunderstood the question, I will solve it another way that I think you meant. (-5x)^4 is -5^4 times x^4.

-625 times x^4 is -625x^4.

Find ST. Help me solve please and thank you
slava [35]

Answer: ST is equal to 12

Step-by-step explanation:

If RU  is equal to 24 as a whole  and we are given that RS and TU are equal to 6 then we could set up an equation and solve for ST.

6 + 6 +x  = 24   where x is the length of ST

12 + x = 24  

-12         -12

x = 12

The volume of a gas is 10.0 liters and its pressure is 1.5 atm. If the pressure is decreased to 0.75 atm,
JulsSmile [24]

Answer:

The new volume is 20litres

Step-by-step explanation:

This problem bothers on the expansion of gases

According to Boyle's law

The volume of a given mass of gas at constant temperature is inversely proportional to the pressure

P∝1/v

Pv= constant

Given data

P1= 1.5atm

v1 = 10 litter

P2=0.75atm

v2=?

Applying P1v1= P2v2

v2= P1v1/P2

v2= 1.5*10/0.75

v2= 15/0.75

v2= 20litres
