What’s 0.0025 cm written in scientific notation
0.0025 cm in scientific notation is 2.5 x 10⁻³cm.
It represents the number 2.5 multiplied by 10 raised to the power of -3, indicating the decimal point moved 3 places to the left, making the number smaller.
To write 0.0025 cm in scientific notation,
we need to express it in the form of a number between 1 and 10, multiplied by a power of 10.
The given number is 0.0025 cm.
To convert it to scientific notation,
we can move the decimal point to the right until it becomes a number between 1 and 10.
The number of places we move the decimal point gives us the power of 10.
Therefore, 0.0025 cm can be written in scientific notation as 2.5 x 10⁻³ cm.

Identify the initial amount a
and the rate of growth r
(as a percent) of the exponential function y=10(1+0.4)t
. Evaluate the function when t=5
. Round your answer to the nearest tenth.
In the equation y=10(1+0.4)t, the initial amount a is 10 and the rate of growth r is 40%. Evaluating this exponential function when t=5 gives us a value of 56.2.
Explanation:In the exponential function y=10(1+0.4)t, the initial amount a is indicated by the coefficient of the function, which in this case is 10. The rate of growth r can be determined from the value added inside the parentheses, given as 0.4, which when converted to percent is 40%. Now, to evaluate the function when t=5, you substitute 5 for t in the equation y=10(1+0.4)*5.
Solving this: y=10*(1+0.4)5 = 10*(1.4)^5 = 56.2 (rounded to the nearest tenth).

Type an integer or a decimal.)b. If you send or receive an average of 5050 text messages each month, which plan would you choose? Why?The plan with ▼ because ▼ than?
text messages are sent or received each month.
Answer:
a.150
Step-by-step explanation:
We are given that a cell phone provider offers a plan that cots $30 per month plus $0.20 per text message sent or received.
A comparable plan costs $60 per month but offers unlimited text messaging.
a.If number of text messages sent or received =150
For I plan
Cost of one text message sent or received per month=$0.20
Cost of plan per month=$30
Costs of 150 text messages sent or received=[tex]0.20\times 150=$30[/tex]
Hence, total costs of plan I =$30+$30=$60
But in II plan no charge for text message and cost of plan per month is $60
Hence, the text messages 150 would have to be sent or received in order for the plans to cost the same each month.
b.If number of text messages =50
Then the cost of messages in plan I=[tex]02.0\times 50[/tex]=$10
Cost of plan I =$30
Total cost of plan I=30+10=$40
But in second plan no charge for text messaging and cost per month is $60.
Therefore, plan I is better than second plan.Because the cost of plan I is less than the cost of second plan per month.

Answer:
Jadyn's claim is wrong.
Step-by-step explanation:
We are given the following information in the question:
Weight of Jadyn's fish = 2.120
Weight of Leah's fish = 2.12
Jadyn says his fish weighs more because 120 is larger than 12.
Jadyn is incorrect claiming the above fact as:
[tex]2.120 = 2.12\\\\2.120 = \displaystyle\frac{2120}{1000} = \displaystyle\frac{212}{100} = 2.12[/tex]
120 parts out of 1000 are compared to 12 parts of 100 which is equal.

For what value of x will 9, 16 and x have the same mean (average) as that of 26 and 12?
The value of x that will make the mean of 9, 16 and x to have the same mean as the mean of 26 and 12 is 32.
Mean is also known as the average of a set of numbers. It is the sum of a set of numbers divided by the total numbers.
Mean = sum of numbers / total numbers
Mean of 26 and 12
(26 + 12) / 2
= 38 / 2 = 19
Mean of 9, 16 and x must equal 19. This can be represented with this equation:
(9 + 16 + x) / 3 = 19
In order to determine the value of x, multiply both sides of the equation by 3
(9 + 16 + x) = 19 x 3
(9 + 16 + x) = 57
Combine similar terms
x = 57 - 9 - 16
x = 32

The values that belong to the solution set are [tex]\(-3\), \(-6\), and \(-4\)[/tex]
To solve the inequality[tex]\(9 \leq 6 - y\)[/tex], we need to isolate the variable \(y\). Let's do this step by step:
1. Subtract 6 from both sides of the inequality:
[tex]\[9 - 6 \leq 6 - 6 - y\][/tex]
[tex]\[3 \leq -y\][/tex]
2. To isolate [tex]\(y\)[/tex], multiply both sides by -1. Remember, when you multiply or divide by a negative number, the direction of the inequality sign reverses:
[tex]\[-1 \cdot 3 \geq -1 \cdot (-y)\][/tex]
[tex]\[-3 \geq y\][/tex]
Now, we have [tex]\(y \leq -3\).[/tex]This inequality states that any value of [tex]\(y\) t[/tex]hat is less than or equal to -3 is a solution.
Let's check each given value to see if it satisfies the inequality:
[tex]- \(0 \): \(0 \nleq -3\) (False)[/tex]
[tex]- \(3 \): \(3 \nleq -3\) (False)[/tex]
[tex]- \(-3\): \(-3 \leq -3\) (True)[/tex]
[tex]- \(-1\): \(-1 \nleq -3\) (False)[/tex]

The values that belong to the solution set are [tex]\(-3\), \(-6\), and \(-4\).[/tex]
In conclusion, the solution set of the inequality [tex]\(9 \leq 6 - y\) is \(y \leq -3\),[/tex] and the values from the given options that belong to this solution set are [tex]\(-3\), \(-6\), and \(-4\).[/tex]

Kala found an icicle 26 inches long. How long is it in feet?
Answer:
It is 2.1 feet in length.
Step-by-step explanation:
You have to divide 26 by 12 since 12 inches are in 1 foot.
Kala's 26-inch long icicle is approximately 2.17 feet when converted from inches to feet using the conversion factor of 1-foot equals 12 inches.
Converting Inches to Feet
Kala found an icicle that is 26 inches long. To convert inches to feet, we need to know that 1 foot is equal to 12 inches. Therefore, we will divide the total length in inches by 12 to find the length in feet.
Start with the total length in inches: 26 inchesUse the conversion factor: 1 foot = 12 inchesDivide the length in inches by 12: 26 ÷ 12 = 2.17So, the icicle is approximately 2.17 feet long.

what is the measure of <RST (MULTIPLE CHOICE)
Answer:
Option D, 77°
Explanation:
The image shown depicts two chords within a circle intersecting creating four separate central angles, two of which have arc measurements listed on the outer edges.
Central angles have the same measurement as the arcs they create, therefore if the arc around ∠RST is 77°, ∠RST itself must have a measurement of 77°.
