The number 50 is 5 times as many as 10?
Answer:
yes you are correct 50 is 5 times as many as 10 because 10 times 5 is 50 thank me later
Step-by-step explanation:
The statement is indeed correct: 50 is 5 times as many as 10. This understanding comes from the powers-of-ten notation system. We can also relate this to the concept of order of magnitude; the order of magnitude of 50 is 10², providing an approximation of its size in powers of ten.
Explanation:The question is asking if the number 50 is 5 times as many as 10. In mathematics, if you multiply 10 by 5, you do get 50, so the statement is indeed correct. This concept is part of multiplication and understood by using the powers-of-ten notation system, which is based on increases of ten.
The powers-of-ten notation system is the basis of our counting system, where each digit's place is ten times greater than the digit to its right. This notation system is used because humans have ten fingers and started counting with them.
An interesting approach is to relate this to order of magnitude. The order of magnitude of 50 is 10² because it's closer to 10² (100) than 10³ (1000). The order of magnitude only changes when you pass the square root of 10 (~3.16). Since 5 is greater than 3.16, when you multiply it by 10, it surpasses 10² (100), giving the order of magnitude as 10³. This is slightly off from the actual value of 50, illustrating how order of magnitude provides an approximation, not an exact value.

Write 0.46 as a fraction simplest form
Answer:
23/50
Step-by-step explanation:
.46
There are 2 numbers after the decimal so we put it over 1 plus 2 zero's
46/100
Divide the top and bottom by 2
46/2 = 23
100/2 = 50
23/50
This is simplest form since 23 is prime and it does not go into 50 evenly
solve the proportional equation
5/12 = x/15
Answer: 6.25.
Step-by-step explanation:
Let's put your question into a proper proportional form, because it is a ratio that is equal.
[tex]\frac{5}{12} = \frac{x}{15}[/tex]
To solve proportions, you have to cross-multiply in the direction that has numbers, which is 5 and 15, then divide to 12.
[tex]5 * 15 / 12 = 6.25[/tex]
The answer you should get by doing this is 6.25.
Answer:
x=6.25
Step-by-step explanation:
Cross multiply
5/12=x/15
12*x=15*5
12x=75
Divide both sides by 12 to isolate the variable x
x=6.25
Or, multiply both sides by 15 to "reverse" the division being done to x
5/12=x/15
15*5/12=x/15*15
6.25=x
for a different punch recipe, the equation,s=4c represents the number of cups of seltzer,s, that you need for,c, cups of cranberry juice. what is the constant of proportionality?
Answer:

Natalia is a teenager and a customer of this company and her average savings was $470 per year. What is the z-value for Natalia’s savings rounded to the nearest hundredth?
Question 1 options:
a)
The z-value is -0.90.
b)
The z-value is 0.90
c)
The z-value is 0.31.
d)
The z-value is -0.31.
Answer:
d) The z-value is -0.31
Step-by-step explanation:
-Given that Natalia's saving is $470, mean claim amount is $490 and the standard deviation is $65
-Let Natalia's savings be X
#The z-value is calculated using the formula:

Answer:
676000
Step-by-step explanation
3 digits of the 5-digit code are number 0-9 which is 10 numbers that could go into that spot, after the three digits there are two letters and because there are 26 letters in the alphabet you would multiply 10*10*10*26*26 which equals 676000

Answer: -118

first multiply by 40. 37x 40 is 1480. No subtract 64 from both sides (1416). Multiply both sides by negative one to make the parentheses positive. -(1416)
on the inside that would be 12y so divide -1416 by 12 which is -118

How can I identify the shaded part of 100 grid as a fraction and a decimal?
To identify the shaded part of a 100 grid as a fraction, count the shaded squares; each represents 1%, making the denominator 100. The fraction formed can be simplified if possible, and converting it to a decimal involves dividing the numerator by the denominator.
To identify the shaded part of a 100 grid as a fraction and a decimal, you must first count the number of shaded squares. Since each square represents 1% of the total grid, the number of shaded squares can be directly written as a percent. For example, if 45 squares are shaded, the shaded part would represent 45%.
As a fraction, this is equal to 45/100, because the denominator should be 100 in order to represent a percent as a fraction.
To convert this fraction to a decimal, divide the numerator by the denominator which gives 0.45. If you have shaded half the grid, it means 50 squares are shaded out of 100. The fraction would therefore be 50/100, which simplifies to 1/2, and the decimal would be 0.50.

There will be 8 grams left after 36 minutes.
Step-by-step explanation:
A half-life is how long it takes for half of the amount to go away. in this case, we see that we have two half-life periods worth, which you can determine by dividing the total time by the half-life time.
36mins/16mins = 2 half lives.
now we can raise 1/2 to the power of how many half lives we have (2). then we multiply that by the amount in the sample.
(1/2)^2 * 36
1/4 * 36
8 grams
Assume that 2 cards are drawn from a standard 52-card deck. Find the following probabilities.

a. The probability of drawing 2 tens without replacement is
(Simplify your answer.)
b. The probability of drawing 2 tens with replacement is
(Simplify your answer.)
Answer:
Step-by-step explanation:
WITHOUT replacement of first card drawn:
P(a 10 is drawn) = 13/52 = 1/4
P(the next draw is a 10) = 12/52 = 3/13
P(drawing two 10s without replacement of the first draw) = (1/4)(3/13) = 3/52
WITH replacement of first card:
P(two 10s are drawn) = P(first card is a 10)*P(first card is a 10) = (4/13)(4/13) =

Three numbers that add up to 30
Answer:
1+2+27=30
3+6+21=30
20+3+7=30
So many more, but here are a few.
To find three numbers that add up to 30, you can choose different combinations. For example, you could use 10, 10, and 10 or figures like 15, 10, and 5. The specific numbers can vary based on the criteria involved.
Explanation:When dealing with numbers that add up to a specific value, there are many possible combinations depending on the criteria you use. For example, if you wish to find three different positive numbers that add up to 30, you could choose 10, 10, and 10. This is because each number is significant and can be repeated in this scenario. These would add up to 30, as 10+10+10 equals 30.
Alternatively, you could choose a variety of numbers such as 15, 10, and 5, which also add to 30. Here the expression is set up as 15 + 10 + 5. Another option could be three unit conversion factors like 12, 8, and 10. The method of finding three numbers that add up to a certain sum is an extension of practical problem-solving often used in daily life.

amount of sales will each need to make

gross pay?

Hal and Sal need to make $500 in sales to have their pay equal. Their gross pay will be $350 each.
Explanation:To find the amount of sales that Hal and Sal need to make their pay equal, we can set up an equation.
Let's say the amount of sales that Hal needs to make is x.
Hal's base wage is $150 per week, and he also earns a 40% commission on total sales. So his total pay can be expressed as:
Total Pay = Base Wage + Commission
Total Pay = $150 + (40% * x)
Similarly, Sal's total pay can be expressed as:
Total Pay = $175 + (35% * x)
To find the amount of sales that makes their pay equal, we can set these two equations equal to each other:
$150 + (40% * x) = $175 + (35% * x)
Now we can solve for x:
$150 + 0.4x = $175 + 0.35x
0.4x - 0.35x = $175 - $150
0.05x = $25
x = $25 / 0.05
x = $500
So, to make their pay equal, Hal and Sal both need to make $500 in sales.
To find their gross pay, we can substitute the value of x into the equations for their total pay:
Hal's Gross Pay = $150 + (40% * $500) = $150 + $200 = $350
Sal's Gross Pay = $175 + (35% * $500) = $175 + $175 = $350
