Rewrite using a single positive exponent.
7^4 * 7^-9

Answers

Answer 1

Answer:

The expression $7^4 * 7^(-9)$ is equivalent to $1/7^(5)$ .

To rewrite the expression using a single positive exponent, we can use the properties of exponents.

Recall the property of exponents that says $a^m * a^n = a^(m + n)$ . This means that when you have the same base raised to different exponents and they are multiplied, you can add the exponents.

$7^4 * 7^(-9) = 7^(4 - 9)$

Now, simplify the exponent:

$7^(4 - 9) = 7^(-5)$

Recall another property of exponents that states $a^(-n) = 1 / a^n$ . This means that when you have a negative exponent, you can rewrite it as the reciprocal of the base raised to the positive exponent.

$7^(-5) = 1 / 7^5$

So, the expression $7^4 * 7^(-9)$ is equivalent to $1/7^(5)$ .

How is the difference 14/15-5/12 written as a decimal?

Answers

14 / 15 - 5 / 12 LCM of 12 and 15 is 60.

(14/15)*(60/60) - (5/12)*(60/60)

= 56 / 60 - 25 / 60

= (56 - 25) / 60

= 31 / 60. To change to decimal, use your calculator.

Which is the area of the figure? Can Someone Please Help Me. A. 192 square inches

C. 392 square inches
D. 480 square inches

Answers

Rather than thinking of it as one shape, think of it as 3 shapes; 3 rectangles. The large section on the left side of the figure is one, and the two parts that stick out on the right side are 2. On the bottom right, two measurements are given; 13, which is the width of the bottom-right rectangle, and the height is 4. 13*4 is 52, which is the area of the bottom-right rectangle. Since the area of the top-right rectangle is equivalent to the area of the bottom right one, it is also 52. Finally, for the large rectangle on the left. Since the entirety of the width of the shape is 24, And the width of the right side is 13, 24-13 is 11. That means that the width for the large rectangle is 11, and it already gives you the height; The 12 on the inside of the shape and the Two heights of 4 for the right-side rectangles. 12 + 4 + 4 is 20, so that means that the area of the large rectangle is 20*11, which is 220. 220 + 52 + 52 is 324. The area for the figure is B, 324. Don't forget to choose which answer is the Brainliest!

Which is the least? 3.95, 3 5/6, 3 4/5

Answers

3 4/5
=3.8

3 5/6
=3.8333333333333...

3.95

Therefore, 3 4/5 is the smallest of the three numbers.

3 4/5 : 3.8

3 5/6 : 3.83333333 and so on

3.95 : 3.95

so the answer is 3 4/5

Find the perimeter of the trapezoidal brick to the nearest tenth of an inch.

Answers

Answer:

The perimeter of the figure is 50 feet.

Step-by-step explanation:

The trapezoid is attached.

Remember, the perimeter is the sum of all sides. But, in this case, we don't know the lenght of all sides. So, we need to find them.

Notice that the missing side on the left is congruent to the vertical leg of the right triangle. So, we use the Pythagorean Theorem to find it. Also, observe that the horizontal leg of the right triangle is 6 feet long.

$10^(2) =6^(2) +h^(2) \nh^(2)=100-36\n h=√(64)=8$
