how do you write 3,901.25 as a scientific notation?
Answer: 3.90125×10⁻³
Step-by-step explanation:
The scientific notation consists of two parts
the number based: a, where 0<a<10the exponent based: 10ˣ, which is determined by how we change the number based "a"So the final version should be: a×10ˣ
-------------------------------------------------------------------
STEP ONE. Number based
We are given 3,901.25
In order to make it within the range of a, we should move the decimal to the left three places, or divide the number by 10³, which is times 10⁻³
We get 3.90125
STEP TWO: Exponent based
Since we changed the number by 10⁻³, this will be our exponent-based.
Therefore, it is 3.90125×10⁻³
Hope this helps!! :)

On a recent survey, 60% of those surveyed indicated that they preferred walking to running.
If 540 people were surveyed, how many preferred walking to running?
*Remember: change your % to a decimal and multiply by the other number
A 480 people
B 425 people
C 324 people
D) 32 people
Answer:
324 people, C
Step-by-step explanation:
You first make 60 percent a decimal by moving the deciaml point up two digits, which makjes the number .60. Then, multiply 540 x .60 which gets your 324.
The side of polygone have length 5,7,8,11&9, the perimeter of similar polygone is 75cm ,finde the length of the side of large polygon?
Answer:
The side lengths of the larger polygon are;
15 cm
20.625 cm
16.875 cm
9.375 cm
13.125 cm
Step-by-step explanation:
Firstly, we need to calculate the perimeter of the first polygon
Mathematically, we can get this by adding the side lengths together
We have this as;
5 + 7 + 8 + 11 + 9
= 40 cm
so we have the ratio of the lengths of both as;
75 cm/40 cm = 1.875
Now, we simply will multiply the lengths of the smaller polygon by 1.875
So we have the side lengths of the bigger polygon as;
1.875 * 5 = 9.375 cm
1.875 * 7 = 13.125 cm
1.875 * 8 = 15 cm
1.875 * 9 = 16.875 cm
1.875 * 11 = 20.625 cm
Explain why the exponents cannot be added in the product 12^3 x
11^3.
Answer:
see explanation
Step-by-step explanation:
The exponents can only be added if the bases are the same
Here one base is 12 and the other is 11
So the rule of addition is not applicable.
Answer:
Because the bases (12 and 11) are different.
Step-by-step explanation:
You can only add exponents when the bases are the same.
Two athletic shoe brands were studied to see which brand was manufactured with the least amount of defects. Brand A was found to have 5 out of 600 pairs of shoes with a defect. Brand B was found to have 5 out of 250 pairs of shoes with a defect.
Which brand of shoes is most likely to have defects in their shoes? Explain your reasoning.
Brand B of shoes is most likely to have defects in their shoes.
What is percentage?A relative value indicating hundredth parts of any quantity.
Brand A was found to have 5 out of 600 pairs of shoes with a defect.
Brand B was found to have 5 out of 250 pairs of shoes with a defect.
As per the data the brand B shoes get more often defected.
For every 250, 5 are defected,
The percent probability for brand A is
= 5/250*100
= 2%.
while Brand B

What point on the parabola y=3-x^2 is closest to the point (3,3)?
What is the equation of the line that passes through (4, 3) and (-4, -1)?
y = 2 x + 7
y = + 1
2 x + 1
y = + 7
Answer:
Step-by-step explanation:
First find the slope of the line
(4 , 3) ; x₁ = 4 ; y₁ = 3
(-4,-1) ; x₂ = -4 ; y₂ = -1
slope [tex]= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\[/tex]

carnival. After riding 5 rides, he had $20
left. If each ride costs the same, what
was the price of each?
Answer:
$2
Step-by-step explanation:
Step-by-step explanation:
Given, John had $30
after riding 5 rides, He had $20
( Let's subtract the balance and the balance he had after ride )
$(30 - 20)
$10
Therefore, Each ride costs = $10 ÷ 5
(dividing 10 and 5, we get 2)= $2

Genny is arranging flowers in vases for every 1 rose shes uses 6 tuilps .How many tulips would she use for every 5 roses
Answer:
30
Step-by-step explanation:
Ah okay, so this is a simple proportion.
If 1 rose = 6 tulips, then you just multiply however many roses you have by 6. So in your case, 5 x 6 = 30. So in short, for every 5 roses Genny uses, she will use 30 tulips.
Answer:
30 tulips
Step-by-step explanation:
This question gives us the amount of tulips for one rose.
Let us make 1 rose as r and a tulip is t. Now write an equation for the tulips.
Tulip = 6r
If we have 5r:
5r = 6t x 5
Solve!
5r = 30t
5 roses = 30 tulips

D. 65.22%
Answer: 65.22%
Step-by-step explanation: 15 is more than half of 23 which means it can’t be the other options because the others aren’t more than half.
65.22 % of teachers ordered the salad bar
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
According to the question
A school cafeteria offers three lunch options on Mondays:
Spaghetti, sub sandwiches, or salad bar.
Percentage of teachers ordered the salad bar
Total number of teachers = 23
Total number of teachers ordered the salad bar = 15
= [tex]\frac{15}{23}[/tex]
= 0.6522
= 65.22%
Thus, 65.22 % of teachers ordered the salad bar
