The approximate weights of the two animals are 5.12 x 102 lbs. and 6.8 x 102 lbs. Find the total weight of the two animals. Write the final answer in scientific notation with the correct number of significant digits. Can you please help me and stop deleting my question :(
these are the answers
1.2 x 103 lbs.
1.19 x 103 lbs.
11 x 102 lbs.
5.8 x 102 lb

Answers

Answer: Option A is the correct answer

Step-by-step explanation: I took the test and got it right

The total weight of the two animals is 1.19 x 10³ lbs. So the correct option is B.

Given approximate weights of the two animals are as:

1. 5.12 x 10² lbs

2. 6.8 x 10² lbs

We need to find the total weight of the two animals.

Step 1: Add the weights together:

5.12 x 10² lbs + 6.8 x 10² lbs

Step 2: Perform the addition:

(5.12 + 6.8) x 10² lbs

11.92 x 10² lbs

Step 3: Express the result in scientific notation with the correct number of significant digits:

The first number, 11.92, has three significant digits. To maintain three significant digits in the final answer, we can express it as 11.9 (rounding to the nearest tenth) and adjust the exponent accordingly:

11.9 x 10² lbs

This matches option 2 from your provided answers:

2. 1.19 x 10³ lbs.

So, the correct answer is: 1.19 x 10³ lbs.

A gem store in Fort Lauderdale received a shipment of 1 1/2 pounds of moonstone crystals if these moonstones crystals if these moonstone crystals were separated into 6 equal bags how much would each bag weigh?

Answers

Each bag would weigh 1/4 of a pound

A shipment of 1.5 pounds of moonstone crystals was divided into 6 equal bags. Each bag would weigh 0.25 pounds, which is the same as 4.0 pounds.

How to solve

To solve this problem, we can use the following equation:

total weight / number of bags = weight of each bag

In this case, the total weight is 1.5 pounds and the number of bags is 6. So, the weight of each bag is:

1.5 pounds / 6 bags = 0.25 pounds per bag

Since 0.25 pounds is the same as 4.0 pounds, each bag would weigh 4.0 pounds.

A rectangle has a length of 8 and width of 12. A scale copy was made with a width of 24. What is the area of the new rectangle?

Answers

Answer:

192 feet^2

Step-by-step explanation:

Length X Width = area

Answer:

The area of the new rectangle is 384 square units.

Step-by-step explanation:

For the original rectangle, the length is 8, and the width is 12. For the scale copy, the width is 24 (12 × 2), so the length will be 16 (8 × 2). Multiplying 24 by 16, we obtain 384 as the area of the new rectangle.

[tex]\displaystyle {y^4}[/tex]

Step-by-step explanation:

The GCF of a set of numbers is the biggest divider that will divide all the numbers without leaving a remainder
As an example, the GCF of 4, 8 and 20 is 4, for 3, 4 and 5 it is 1 since there is no common factor

[tex]\textrm {We have the three numbers as }[/tex] [tex]y^4, y^5 \;and\; y^{10}[/tex]

Which of these numbers will divide into each of these without leaving a remainder?

[tex]\mathrm{The \:exponent\:rule}:\quad \dfrac{x^a}{x^b}=x^{a-b}[/tex]

This means the smallest exponent value [tex]y^4[/tex] will be the GCF because
[tex]\dfrac{y^4}{y^4} = 1\\\\\dfrac{y^5}{y^4} = y^{5-4}} = y^1\\\\\dfrac{y^10}{y^4} = y^{10-4}} = y^6\\\\\\[/tex]

Find the slope of the line that has a y intercept of 4 and passes through the point (-3, 1)

Answers

Answer: m = 1 (m is slope)

Step-by-step explanation:

1. y-int is coordinate, so it is (0,4)

2. with (0,4), we can now use (-3,1):
4 - 1 = 3 and with the x, it is 0 + 3 = 3
So, it is 3/3 = 1, so the slope is 1

Answer:

Line L1 : Passes thro' (3,3)

y-intercept = 4 ===> (0,4)

Slope = (4 - 3)/(0 - 3) = 1/-3

Slope of L1 = -1/3.
