Solution :

Give that a shark can chase prey about 30 miles per hour.

1 hour = 60 minute

by using unitary method, we will convert miles per hour into miles per minute

in 60 minutes the shark can chase the prey 30 miles

In 1 minute the shark can chase $\frac{30}{60} miles = \frac {1}{2} miles= 0.5 miles$

Hence the shark can chase the prey about 0.5 miles per minute.

A tissue can be 0.000075 meters thick.

Setler [38]

Answer:

The required expression is $7.5\times 10^5$

Step-by-step explanation:

Consider the provided information.

A tissue can be 0.000075 meters thick and we need to represent it into scientific notation.

Steps to write a number in scientific notation.

Move the decimal place to the right so that the new number from 1 up to 10.

Determine the exponent, the exponent is the number of times you moved the decimal.

Now, consider the number 0.000075

Move the decimal point to 5 place right so that the new number from 1 up to 10.

Now, put the exponent the number of times you moved decimal. $7.5\times 10^5$

Hence, the required expression is $7.5\times 10^5$

Two cities are 3 1/2 inches apart on a map the map scale says that 1/4 inch is 1 mile how many miles apart are the two cities

maria [59]

Answer:

every 1/4 inch on the map is 1 mile.

You need to find the number of 1/4 inches there are in 3 1/2 inches.

There are four 1/4 inches per inch.

3 x 4 = 12

There are two 1/4 inches in 1/2 inch.

12+2 = 14

The cities are 14 miles apart.

Margaret makes bracelets and sells them to tourists. the function s(t) approximates how many bracelets margaret makes per hour.

Fantom [35]

The units for the composite function s(w(h)) is <u>bracelets over a week</u> when the function s(t) approximates how many bangles Margaret makes per hour and the function w(h) represents how many hours per week Margaret spends making the bracelets.

To define the unit of the composite function s(w(h)), we first need to find the units of the functions s(t) and w(h).

The function s(t) represents the number of bangles per hour, so its unit will be bangles over an hour.

The function w(h) represents the hours per week spent on making the bracelets, so its unit will be hours over a week.

Now, we can define the unit of the composite function s(w(h)).

To find the unit of the composite function we follow these steps:-

s(w(h)),

= s(hours over a week) {replacing the function w(h) by its units},

= (bangles over an hour(hours over a week)) {replacing the function s(t) with its units},

= bangles over a week {Simplifying}.

Thus, the units for the composite function s(w(h)) is <u>bracelets over a week</u> when the function s(t) approximates how many bangles Margaret makes per hour and the function w(h) represents how many hours per week Margaret spends making the bracelets.
