Mathematics

tester [12.3K]1 month ago
5 0

The question provided states that,

George took a direct flight from Dallas to Los Angeles covering 1,233 miles. Initially, the plane was traveling at a speed of 460 miles per hour for the first 75 minutes, then at a speed of 439 miles per hour for the remaining duration.

Let x denote the hours during which the flight flew at 439 miles per hour.

Based on this, we can establish the following:

460* \frac{75}{60} + 439*x = 1233

575 + 439x =1233
\\
439x = 1233 - 575
\\
439x = 658
\\
x = \frac{658}{439} hours

To convert this into minutes, we must multiply by 60, resulting in

x = \frac{658}{439}*60 =approx \ 90 \ minutes

Step-by-step explanation:

°C = °K - 273

°F = 9/5 °C + 32

Substitute the first equation into the second

°F = 9/5 (°K - 273) + 32

Svet_ta [12734]

Miguel's batting average is roughly 0.330

Explanation

Miguel Cabrera achieved 205 hits in 622 at-bats.

To calculate batting average, we need to divide the hits by the total at-bats and round the result to three decimal places since batting average is conventionally rounded in this manner.

Hence, Miguel's batting average =\frac{205}{622}=0.32958.... ≈ 0.330 (Rounded to three decimal points)

Response:

Max = 18\ mins

Min = 12\ mins

Step-by-step explanation:

Information given:

Time = 15\ mins

Variation = 3\ mins

Objective:

Calculate the maximum and minimum values

The max value is found as follows:

Max = Time + Variation

Max = 15\ mins + 3\ mins

Max = 18\ mins

The min value is identified as follows:

Min = Time - Variation

Min = 15\ mins - 3\ mins

Min = 12\ mins
