Answer:
<h3>9.43</h3>
Step-by-step explanation:
The formula for calculating the distance between two points is expressed as
D =√(x2-x1)²+(y2-y1)²
Given the coordinates (0,0) and (8,5)
D = √(5-0)²+(8-0)²
D = √5²+8²
D = √25 + 64
D = √89
<em>D = 9.43</em>
<em>Hence the distance between the life guard and the swimmer is 9.43</em>
<em></em>
Answer is C, just multiply and expand.
Answer:
The value of x is 7
Step-by-step explanation:
Complementary angles have a sum of 90°, therefore the equation to solve for x is:
∠1+∠2=90°
60°+5(x-1)°=90°
5(x-1)=30°
x-1=6
x=7
So the value of x is 7

Answer:
Krutika
Step-by-step explanation:
Lets convert each person's typing rate to words/min.
Krutika:
80 minutes = 6000 words
1 minute = (6000/80) words
= 75 words
Typing Rate: 75 words / min
Mark:
60 minutes = 4200 words
1 minute = (4200/60) words
= 70 words
Typing Rate: 70 words / min
David:
90 minutes = 5850 words
1 minute = (5850/90) words
= 65 words
Typing Rate: 65 words / min
From the above, we can see Krutika has the fastest rate of words per minute.
