Mathematics
1 answer:
Schach [20]2 years ago
7 0

Answer:

x = 20

Step-by-step explanation:

There is a right angle which is 90 degrees. Part of the angle is 30 degrees, so the other measure is 60 degrees, which is the 3x.

Make an equation.

3x = 60

Divide both sides by 3

3x/3 = 60/3

x = 20

timurjin [86]
If she goes with the 25% off she will have to pay 28.80

if she uses the $15 off she will have to pay
$35.33 plus the $15 off would be 20.33 so she's better off going through doing it this way rather than the 25% off

Complete Question

Peyton is a sprinter who can run the 40-yard dash in 4.5 seconds. He converts his speed into miles per hour, as shown below.

Which ratio is incorrectly written?

40 yd/4.5 sec • 3 ft/1 yd • 5280ft/1 mile • 60 sec/1 min • 60 min/1 hr

Answer:

5280ft/1 mile is the incorrect ratio

Hence, 40-yard dash in 4.5 seconds = 18.2 miles per hour(mile/hr)

Step-by-step explanation:

We are to convert 40 yards per 45 seconds to Mile per hour.

We are given the following conversion ratios:

40 yd/4.5 sec • 3 ft/1 yd • 5280ft/1 mile • 60 sec/1 min • 60 min/1 hr

The incorrect ratio is 5280ft/1 mile .

It should have been written as 1 mile/5280 ft.

Hence,

40 yd/4.5 sec • 3 ft/1 yd • 1 mile/5280ft• 60 sec/1 min • 60 min/1 hr

= 432000mile/23700 hr

= 18.181818182 mile/hr

Approximately= 18.2mile/hr
