Answer:
Each of the legs of isosceles right triangle is 5
Step-by-step explanation:
Watch the attached figure for the isosceles right angled triangle
Looking at the figure we see that AB=5√6 and BC=CA
According to the Pythagorean theorem the square of the hypotenuse is equal to the sum of the squares of the other two sides of a right triangle.
1) Applying the Pythagorean theorem to the isosceles right triangle, we have
2) Let BC=a and CA=a as they both are equal
So,
=> 
=> 
=> 
(since √6*√6 = (√6)²= 6)
=> 
3) Dividing both sides by 2, we get
4) Cancelling out the 2's on the left, we get
= 75
5) Taking the square root on both sides, we have
=> a = 5
So,
Each of the legs of isosceles right triangle is 5
The answer is y=4x-5. hope that helped
Answer:
The approximate number of gallons of water that flow over the waterfall in 1 day is:
Step-by-step explanation:
To obtain the answer to the question, you must multiply the number gallons of water flow over a waterfall each second (6.5 x 10^5 gal/s) by the number of seconds in a day (8.6 x 10^4 s), as I show you below:
- Gallons of water that flow over the waterfall in 1 day = Number of gallons * Number of seconds in a day.
- Gallons of water that flow over the waterfall in 1 day = 6.5 x 10^5 gal/<u>s</u> * 8.6 x 10^4 <u>s</u>
Now, we must cancel the seconds, then:
- <u>Gallons of water that flow over the waterfall in 1 day = 5.59 x 10^10 gallons</u>
How you can see, <em>once you have multiplied these two values, the answer is the same to the option A</em>.
The temperature is 46°F
Step-by-step explanation:
Given the temperatures in F for the past four days as: 45, 38, 46, 35
The mean for the five days is 42 °F
Find the total temperatures with the mean of 42 in 5 days. Perform multiplication
42*5= 210 ° F
Sum of temperature in 4 days is 45+38+46+35=164 °F
The temperatures for the first day will be : 210°F-164°F=46°F
