Tamika builds a wooden skateboard ramp. The ramp measures 63 centimeters, and the length of its horizontal base is 60 centimeter

Softa [21]

So imma be using the Pythagorean Theorem, which is $a^2+h^2=c^2$ . The a and h variable represent the legs of the right triangle while c variable stands for the hypotenuse. And since we have one of the legs and the hypotenuse, we are solving for the other leg.

So first we are gonna plug in 60 and 63 in their appropriate spots: $60^2+h^2=63^2$

Solve the exponents to get $3600+h^2=3969$

Subtract 3600 on each side to get $h^2=369$

To cancel out the squared power, you have to square root each side of the equation, and your final answer should be $h=19.2$ cm

You are a bus driver and are scheduled to depart from Terminal A at 9:18 a.M. And arrive at Terminal B at 10:03 a.M. You arrive

Vesna [10]

Answer:

9 minutes

Step-by-step explanation:

departure terminal A : 9:18 a.M

arrive terminal B : 10:03 a.M

time between B and A : 60 minutes (1 hour) - 18 minutes + 3 minutes = 45 minutes

arrive to a stop at : 9:58 a.M

time between A and stop : 58 minutes - 18 minutes = 40 minutes

5 mores tops including B

a stop - 1 stop next -2 stops next -3 stops next -4 stops next -B

average time between stops: 2 minutes

loading unloading time : 1 minute

a stop 40 minutes + (2 minutes to stop 1 + 1 minute in stop 1 )+ (2 minutes to stop 2 + 1 minute in stop 2 )+ (2 minute to stop 3 + 1 minute in stop 3 )+ (2 minutes to stop 4 + 1 minute in stop 4 )+ (2 minutes to stop B)

40 + 2 + 1 + 2 + 1 + 2+ 1 + 2+1 +2=54 minutes

real time between terminal B and A : 54 minutes

schedule time between terminal B and A : 45 minutes

minutes past scheduled time to arrive at Terminal B: 54 minutes -45 minutes=

9 minutes

Use scientific notation to estimate the number of inches in 1,225 miles. Include all calculations in your final answer. 1 inch ≈

mr_godi [17]

Answer:

7.763×10^7 inches

Step-by-step explanation:

$(1225\,mi)\dfrac{1\,in}{1.578\cdot 10^{-5}\,mi}=\dfrac{12.25}{1.578}\cdot 10^{2-(-5)}\,in \approx 7.763\cdot 10^7\,in$

When writing 1225 in scientific notation, it is convenient to choose an exponent so that the division result comes out with the right scale factor. It is easy to see that 1.2 < 1.6, so use of numbers with exactly one digit to the left of the decimal point would result in a fraction as an answer. We want the answer to have 1 digit left of the decimal point, so by scaling the operands to be 12. and 1.6, we get that result. Of course, the powers of 10 are adjusted accordingly.

This scaling process only matters if you're computing the results by hand. Any calculator can properly keep track of the required exponents.

"Back in the day" when slide rules were the calculating tool of choice, the operands and answer to any multiplication or division problem were only shown as 3 (sometimes 4) significant digits. All of the power-of-ten scaling was done "by hand" (usually, mentally). That is, the division would be 1225/1578 ≈ 776 × some scale factor. This is where thinking of the numbers as 12.25/1.578 = 7.76 comes in handy.
