To divide fractions, we do Keep, Change, Flip. Keep means that we keep the first fraction the same ( which is 8/1). Then for Change, we change the division sign to a multiplication sign. After that we Flip the second fraction itś reciprocal (or multiplicative inverse).
So your equation would be:

8/1 x 3/1 which equals 24

What is the sum of the digits of 29999999^2?

Answers

Answer:

Sum of digits = 9*6+8+4+1 = 67

Step-by-step explanation:

29999999^2 = 899999940000001

Final answer:

To find the sum of the digits of 29999999^2, calculate the square of 29999999, and then add up the individual digits of the result. Therefore, the sum of the digits of 29999999^2 is 77.

Explanation:

To find the sum of the digits of 29999999^2, we first need to calculate the square of 29999999. This can be done by multiplying 29999999 by itself. After calculating this product, we can add up the individual digits of the result to find the sum.

Calculating 29999999^2 results in a large number: 899999940000001. To find the sum of its digits, we can break down the number: 8 + 9 + 9 + 9 + 9 + 9 + 9 + 9 + 4 + 0 + 0 + 0 + 0 + 0 + 0 + 1 = 77.

Therefore, the sum of the digits of 29999999^2 is 77.

Find the area of the image below:A. 24.6 square units
B. 25.8 square units
C. 26.3 square units
D. 27.5 square units

Answers

Answer:

Option D. $27.7\ units^(2)$

Step-by-step explanation:

we know that

The area of the image is equal to the area of the complete square minus the area of triangle 1, minus the area of triangle 2, minus the area of triangle 3, minus the area of trapezoid 4

see the attached figure to better understand the problem

Find the area of the complete square

$A=8^(2)=64\ units^(2)$

Find the area of triangle 1

$A=(1/2)(4)(5)=10\ units^(2)$

Find the area of triangle 2

$A=(1/2)(3)(3)=4.5\ units^(2)$

Find the area of triangle 3

$A=(1/2)(3)(3)=4.5\ units^(2)$

Find the area of triangle 4

$A=(1/2)(3+4)(5)=17.5\ units^(2)$

The area of the image is equal to

$A=64-10-4.5-4.5-17.5=27.7\ units^(2)$

The area of the given image, calculated using the Shoelace Formula based on the coordinates of its vertices, is 27.5 square units.

The correct answer is option D.

To determine the area of the provided image formed by the points H(0,0), L(1,5), K(4,8), J(-1,8), and I(-4,5), we can employ the Shoelace Formula. This formula calculates the area of a polygon based on the coordinates of its vertices. For a polygon with vertices (x₁, y₁), (x₂, y₂), ..., (xₙ, yₙ), the formula is:

Area = 1/2 * |x₁y₂ + x₂y₃ + ... + xₙy₁ - y₁x₂ - y₂x₃ - ... - yₙx₁|

Applying this formula to the given points:

Area = 1/2 * |(0 * 5 + 1 * 8 + 4 * 8 + (-1) * 5 + (-4) * 0) - (0 * 1 + 5 * 4 + 8 * (-1) + 8 * (-4) + 5 * 0)|

Area = 1/2 * |(0 + 8 + 32 - 5 - 0) - (0 + 20 - 8 - 32 + 0)|

Area = 1/2 * |35 - (-20)|

Area = 1/2 * 55

Area = 27.5 square units

Therefore, the correct answer is D. 27.5 square units.

PLEASE HELP! THANKS!The measures, in degrees, of the 3 angles of a triangle are given by 2x +1, 3x - 3, and 9x.
What is the measure of the smallest angle?

A.) 13 degrees
B.) 27 degrees
C.) 36 degrees
D.) 117 degrees

please show how to solve this I GIVE THANKS!!!

Answers

if you add everything up then
14x-2=180
14x=182
x= 13

So the angles would equal
2(13)+1= 27
3(13)-3= 36
9(13)= 117
The angles are 27 36 and 117
Which makes the smallest angle 27 which is B.

You first have to know that the measure of the three angles of a triangle= 180add the terms and equal them to 1802x+1 + 3x-3 =9x= 18014x-2 = 18014x= 182x=13 This is not what you are looking for, you need tosubstitute 13 in the original measures2 (13) +1= 27 degrees3(13) -3= 36 degrees9 (13) = 117 degreestherefore the smallest angle is 27 degreesif you add all three angle measure it will = 180 degreesHope this helps you
