Which of the following expressions is not equal to 64?

A. 2^4 . 2^-3 .2^4 .2
B. 2^2 .2^8 .2^-4 .2^0
C.2^0 .2 . 2^2 .2^3
D. 2^6 . 2^-3 . 2^4 . 2

Answers

Answer 1

Answer:

A. 2^4 . 2^-3 . 2^4 . 2

Step-by-step explanation:

Option A,

2^4 . 2^-3 . 2^4 . 2

= 2^4 . 2^-3 . 2^4 . 2^1

= 2^( 4 + 4 + 1 - 3 )

= 2^( 9 - 3 )

= 2^6

= 64

So, Option A is the correct answer.

Answer:

Step-by-step explanation:

x²y = k, where k is a real constant.

When x = 3.5, y = 8.

=> (3.5)²(8) = k, k = 98.

When y = 8/9,

we have x²(8/9) = (98).

=> x² = 110.25

=> x = 10.5 or x = -10.5.

Since we want the negative value,

the answer is x = -10.5.

Answer:

A. y = -2x + 2      B. y = x - 1

Step-by-step explanation:

A.

We have two given points, which are (0, 2) and (1, 0). Because one of the given points has the x-coordinate 0, it means it is the y-intercept. The y-intercept is 2, which means that 2 is the B of our equation. Now, I will use the skeleton method to find the slope.

((2) - (0))/((0) - (1)) = -2    

Now we know that -2 is the slope, so we can form the equation.

y = -2x + 2

B.

The line shown in exercise B is actually a 1x equation since it is seen that it goes through every whole number without forming decimals. So our m is 1. The y-intercept, which can be seen by looking at the y-coordinate at x = 0, is -1. So -1 is our B.

The equation is as follows.

y = x - 1

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

Then the tangent of an angle is the ratio of the perpendicular and the base of the right-angle triangle.

The numbers 1 to 8 are placed in a hat. What is the probability that you will pick an odd number, and without replacing the number in the hat, select the number 2?

Answers

Answer:

1 /7

Step-by-step explanation:

Sample space =. (1, 2, 3, 4, 5, 6, 7, 8)

Odd numbers = (1, 3, 5, 7)

Probability of picking an odd number = number of odd numbers / sample space

P(odd number) = 4 / 8 = 1/2

Without replacement :

P(picking a 2) :

Sample space = 8 - 1 = 2

Hence,

P(picking a 2) = 2 / 7

P(picking an odd number and the a 2) =

1/2 * 2/7 = 2 /14 = 1/7

The perimeter

The expression for perimeter is

P= 2L+2W

P= 2(1.5t+6)+ 2(6t-1.5)

open bracket

P= 3t+12+ 12t-3

collect like terms

P= 3t+12t+12-3

P= 15t+9 ft

Hence the perimeter is  15t+9 ft

Step-by-step explanation:

Recall that P = 2W + 2L.  Here L = 10" and P = 34".

Thus, 2(10") + 2W = 34", or

2W = 14"

Then the width of the photo is W = 14" / 2, or 7"

i think the answer would be 7/50

Answer:

7/50 is the correct answer

Step-by-step explanation:

First you would need to convert this to an improper fraction which it would be 0+14/100.

Then you would add 0 and 14/100 to get the same answer 14/100

After this you would factor out the 14 and 100

Finally you should get

2(7)/ 2(50)

Now you should be able to cancel out the 2 and be left with 7/50.
