Which choice is equivalent to the expression below?2^8.24

A. 2^8+2^2/10+2^4/100
B.2^8*2^2/10*2^4/100
C. 2^8*2^24/10
D.2^8+2/10+4/10

Answers

Answer:

2^(8)\cdot 2^{(2)/(10)}\cdot 2^{(4)/(100)}

B is correct

Step-by-step explanation:

Given: 2^(8.24)

Using exponent law,

x^(a+b)=x^a\cdot x^b

Expand exponent 8.24

Position of each digit:

8 ⇒ It is at tens place (1 x 8)

2 ⇒ It is at tenth place (1/10 x 2)

4 ⇒ It is at hundredth place (1/100 x 4 )

8.24=8+.2+.04

8.24=8+(2)/(10)+(4)/(100)

2^(8.24)=2^{8+(2)/(10)+(4)/(100)}

Using exponent law

2^(8.24)=2^(8)\cdot 2^{(2)/(10)}\cdot 2^{(4)/(100)}

Hence, The equivalent expressionis2^(8)\cdot 2^{(2)/(10)}\cdot 2^{(4)/(100)}
B is your answer because if you check each one in the calculator B is the same as the expression and also 2^8 makes up the first part and the second half makes up the .24

ox is 6 times the weight of tiny, yet tiny can lift ox even when he's holding 80 pounds. tiny is holding up 410 pounds right now (ox plus 80 lbs). How much does tiny weigh.

Answers

Answer:

55

Step-by-step explanation:

Find the weight of OX:

If Tiny is carrying 410 pounds, 80 of which are not Ox, then subtract the 80 from the 410.

410-80=330

Now divide the weight of Ox by six, since he weighs six times more than Tiny.

330/6=55

Therefore Tiny is 55 Pounds.

Let f(x) = -x + 5 and g(x)=3x+ 2. Find f(x) – g(x).

Answers

Answer: f(x) - g(x) = -4x+3

=============================================

Work Shown:

f(x) - g(x) = ( f(x) ) - ( g(x) )

f(x) - g(x) = ( -x+5 ) - ( 3x+2 )

f(x) - g(x) = -x+5 - 3x - 2

f(x) - g(x) = (-x-3x) + (5-2)

f(x) - g(x) = -4x+3

In step 3, make sure to distribute the negative to everything in the parenthesis for (3x+2)

the ski team has a race in 3 hours and it is 120 miles away. the team drives 50 miles each hour. will they arrive at the same time?

Answers

They won't arrive exactly when the race starts, but they will arrive before the race starts because, assuming they leave exactly three hours before the race, they can drive a total of 150 miles in three hours (3h*50mi/h). Because they only need to drive 120 miles, they will make it to the race before it starts.
