Answer:

B. 63.8 mph

Step-by-step explanation:

IN order to solve this problem we just have to keep in mind that the miles per hour is calulcated by the number of revolutions that the tire is doing multiplied by the circumference of the tire, so the circumference of the tire is given by the first set of number in the tire the first one would be:

first:\frac{215}{60} \\Second: \frac{235}{70}

So we just have to multiply it by the first one and then divide it by the second:

\frac{215}{60}*60=215\\215*\frac{235}{70}=63.8

SO when the speedometer is on 60 mph, he will actually be going at 63.8 mph.

Answer:

Step-by-step explanation:

sin²β + sin²β×tan²β = tan²β

sin²β( 1 + tan²β ) = tan²β

~~~~~~~~~~~~~~~~

<u><em>sin²β + cos²β = 1  </em></u>

<u><em /></u>\frac{sin^2\beta }{cos^2\beta } + \frac{cos^2\beta }{cos^2\beta } = \frac{1}{cos^2\beta } ⇒ tan²β + 1 = sec²β ⇔ 1 + tan²β = sec²β

~~~~~~~~~~~~~~

1 + tan²β = \frac{1}{cos^2 \beta }

L.H. = sin²β ( \frac{1}{cos^2 \beta } ) = tan²β

R.H. = tan²β

dem82 [27]

We are given radius = 6 yards

area of circle = pi * r * r = 3.14 * 6*6 = 113.04 yard square

cost of carpet is $14 per square yard

cost of 113.04 square yard = 14*113.04= 1582.56 dollars

Answer: cost to carpet the planetarium is $1582.56
