Answer:
a
Step-by-step explanation:
just did it
We know the triangle is an isosceles triangle. So, we use the Pythagorean Theorem.
a^2+b^2=c^2
The c would be 22, because it's the longest edge. Now find a or b. They are the same, that is how you find the two sides of the triangle for part A.
To find the area of the triangle, the forumla is a=hb/2
Plug in the numbers for that formula and the answer would be found for part B.
I hope I helped.
Answer:
18, 21, 36
Step-by-step explanation:
Let L represent the least number. Then the greatest is 2L and the middle number is (L+3). Their sum is ...
L +(2L) +(L+3) = 75
4L = 72 . . . . . . . . . subtract 2, collect terms
L = 18 . . . . . . . . . . . divide by 4
L+3 = 21
2L = 36
The numbers are 18, 21, and 36.
Answer:
Step-by-step explanation:
Let's assume this is a function
<u>The points are</u>
<u>Since it is linear relation, we'll get the slope intercept form</u>
- g = ms + b, where g- number of gallons, s- time in seconds, b- y intercept
<u>Using the points, let's calculate the formula</u>
- m = (10 - 13)/(60 - 40) = -3/20
- 10 = -3/20*60 + b
- 10 = - 9 + b
- b = 19
<u>So the formula is:</u>
