Answer: base a=2ft
height hₐ=5ft
Step-by-step explanation:
use equation for area of triengle
A=a*hₐ/2
hₐ-height of tringle
a-base of triangle
hₐ=a+3
A=a(a+3)/2
2A=a²+3a
A=5ft
2*5=a²+3a
a²+3a-10=0
a=(-3±√9+40)/2
a=(-3±7)/2
a=-5ft
a=2 ft
hₐ=2+3=5ft
Answer:
<h2>25 mph</h2>
Step-by-step explanation:
<h3>
Step 1: Convert miles to feet</h3>
First, we need to convert the miles to feet keeping in mind that:
1 mile = 5,280 feet
655 ft 19 sec
5,280 ft 4 min 24 sec
<h3>Step 2: Divide the distance by the time to find the unit rate</h3>
3,447 feet per minute
1,245 feet per minute
<h3>Step 3: Convert minutes to hours</h3>
206,820 feet per hour
74,700 feet per hour
<h3>Step 4: Convert feet to miles</h3>
39.17 miles per hour
14.15 miles per hour
To find how much faster Michael ran, we need one more step.
<h3>Step 5: Subtract smaller amount from larger amount</h3>
39.17 - 14.15 = 25
I'm always happy to help :)
1.
18.98 per 1000
320,000 / 1000 = 320
18.98 x 320 = $6073.60
2. smoker: 9.36 * 100 = 936
non smoker: 7.85 * 100 = 785
936 - 785 = $151
