To calculate total earnings: 40 hours multiplied by $8.95 leads to earnings of $358. After deducting expenses, the total earnings would be $358 - ($35.24 + $24.82 + $21.33) = $276.61.
Answer:
Upper limit: 3.116
Lower limit: 3.125
Step-by-step breakdown:
The random circle drawn by Hellen has a circumference of C=405 mm, measured to 3 significant figures, leading to a diameter, d, of 130 mm, accurate to 2 significant figures.
We utilize the formula

Substituting in the figures provides:


Consequently, Hellen’s value for π is recorded as 3.115 to three decimal places.
To find both limits, we divide the specified level of precision by two.

This figure is then added to the rounded number to determine the upper limit:
3.115+0.0005=3.1155
The lower limit calculates as 3.115-0.0005=3.1145

The value of y that would ensure OP runs parallel to LN is 36. Step-by-step explanation: This pertains to the concept of similar triangles. The diagram based on the provided data is attached. Given: The length of OL is 14, OM is 28, MP is y, and PN measures 18. The total length of MN is the combination of MP and PN, expressed as y + 18. The length ML is calculated as MO plus OL, giving us 28 + 14 = 42. For OP to be parallel to LN, the ratio MO to ML must equal MP to PN, formulated as MO/ML = 28/42 and MP/PN= y/(y+18). By equating both ratios 28/42 = y/(y+18), it simplifies to 42y = 28(y + 18). Solving for y leads to 42y being equal to 28y + 504, resulting in 14y = 504. Thus, y equals 504/14 = 36.
