If 15% of x is 42, what is x?
Answers
The required whole value of x is 280 if 15% of x is 42.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
For example, If Misha obtained a score of 67% on her exam, that corresponds to 67 out of 100. It is expressed as 67/100 in fractional form and as 67:100 in ratio form.
To determine the value of x, we can set up the equation: (15/100)x = 42.
This equation states that 15% of x is equal to 42.
To solve for x, we can divide both sides of the equation by (15/100) to get:
x = (100/15) × 42
x = 280
So x = 280.
This means that if 15% of x is 42, then the whole value of x is 280.

Estimate 11.14+9.543 by first rounding each number to the nearest tenth.
HELP PLSZZ
Answers
To round each number to the nearest tenth, we have to look at the second digit after the decimal point, the hundredths. We look at tenths to round whole numbers, hundredths to round tenths, thousandths to round hundredths, etc. If the digit is 4 or below, then we would round down. If the digit is 5 or up, we would round up.
11.14
The digit is below 5, so we round down to 11.1.
9.543
The digit is also below 5, so we round down to 9.5.
Henceforth, adding these two numbers, we can conclude that an accurate estimation of the sum is 11.1 + 9.5, or 20.6.
If we wanted to round this answer further, we would use the same rounding rule. 20.6, where the tenths place digit, 6, is above 5, would be rounded up to 21.
total shrink for a three- and four-bend saddle is twice that of an offset. True or false?
Answers
False. The total shrink for a three- and four-bend saddle is equal to that of an offset.
The statement "total shrink for a three- and four-bend saddle is twice that of an offset" is true.
1. Shrink: Shrink refers to the amount of extra conduit length needed to account for bends in the conduit, so it maintains the required distance between two points after bending.
2. Offset: An offset is a two-bend conduit configuration used to navigate around obstacles while maintaining a straight path. The total shrink for an offset can be calculated using the formula: Shrink = offset height x (multiplier for the specific angle).
3. Saddle: A saddle is a conduit configuration with either three or four bends. It is used to navigate over or under obstructions while maintaining a straight path.
4. Comparison: For both three- and four-bend saddles, the total shrink is twice that of an offset. This is because a saddle consists of two sets of bends (either two offsets or an offset and a U-bend) and requires additional conduit length to accommodate these extra bends.
In conclusion, the statement is true, as the total shrink for a three- and four-bend saddle is indeed twice that of an offset.

If Reginald Wallace’s gross weekly salary is $515 and the Medicare tax is 1.45 percent of gross pay. The state tax is 1.5 percent of gross pay. The amount that is deducted from Wallace’s weekly wages for state tax and Medicare tax is: $15.19.
State tax and Medicare taxState tax=1.5 percent of gross pay
Medicare tax=1.45 percent of gross pay
State tax=$515 ×0.015
State tax= $7.725
Medicare tax=$515× 0.0145
Medicare tax = $7.4675
Hence:
State tax and Medicare tax=$7.725+$7.4675
State tax and Medicare tax=$15.1925
State tax and Medicare tax=$15.19 (Approximately)
Therefore If Reginald Wallace’s gross weekly salary is $515 and the Medicare tax is 1.45 percent of gross pay. The state tax is 1.5 percent of gross pay. The amount that is deducted from Wallace’s weekly wages for state tax and Medicare tax is: $15.19.

Provide an appropriate response. Use the Standard Normal Table to find the probability. Show your work.The distribution of cholesterol levels in teenage boys is approximately normal with mean=170 and standard deviation=30. Levels above 200 warrant attention. If 95 teenage boys are examined, how many would you expect to have cholesterol levels greater than 225?
Answers
We will expect 3 teenage boys out of the 95 examined to have cholesterol levels greater than 225.
How many teenage boys is expected to have greater than 225?Given:
Mean (μ) = 170
Standard Deviation (σ) = 30
We will get z-score for the cholesterol level of 225 using the formula: z = (x - μ) / σ
Substituting values:
z = (225 - 170) / 30
z = 55 / 30
z ≈ 1.83
Using standard normal distribution table, we find that the area to the right of z = 1.83 is 0.0336.
Now, we wil multiply proportion by the total number of boys examined.
Number of boys = Proportion × Total number of boys
Number of boys = 0.0336 × 95
Number of boys = 3.19
Number of boys = 3.
