At a temperature of t degrees Fahrenheit, sound travels s feet per second, where s equals 21.9 StartRoot 5 t plus 2457 EndRoot

mafiozo [28]

Answer:

32.63 F

Step-by-step explanation:

The function:

$s = 21.9 \; \sqrt{ 5 t + 2457 }$

represents sound travels s at feet per second, where t is the temperature at Fahrenheit degrees.

We know that sound traveled at a rate of 1121 ft/sec. To find the temperature we need to replace with s value and isolate t for the above function.

$1121 = 21.9 \; \sqrt{ 5 t + 2457 }$

$\frac{1121}{21.9} = \sqrt{ 5 t + 2457 }$

$51.19^2 = 5 t + 2457$

$2620.13 - 2457 = 5 t$

$\frac{163.13}{5} = t$

$32.63 \; F= t$

Use the diagram to determine the base and the height of the triangle. The formula for the area of a triangle is A=bh/2

Arlecino [84]

The answer is 32ft. What you have to do is multiply 10 and 6.4 which equals 64. Then you take 64 and divide it by 2 and you get the answer of 32. The equation goes like this 10ft X 6.4ft = 64ft/ 64ft divided by 2 = 32ft.
