Answer:
The answer is below
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, acute, scalene, obtuse, right and equilateral triangle.
A scalene triangle is a triangle in which all the three sides of the triangle have different lengths hence, all the angles of the triangle also have different lengths.
Therefore the set of straw lengths that can be used a scalene triangle must have different lengths, for example:
5, 7 , 8
Keri= 13/32x100/1=40.6%
Mathew=15/43x100/1=34.8%
Liam=12/28=3/7x100/1=42.86%
Highest=Liam
Lowest=Matthew
Answer: Cruz's biking is 16 miles per hour and his running speed is 10 miles per hour.
Step-by-step explanation:
Let x represent Cruz's speed when running.
He left his house at 6:00 and ran until 7:30. This means that the time spent while running is 1hour 30 minutes = 1.5 hours.
Distance = speed × time
Distance covered while running would be
1.5 × x = 1.5x
Then he rode his bike until 9:45. This means that the time he spent riding his bike is 2hours 15 minutes = 2 hours + 15/60 = 2.25 hours
His speed when biking was 1.6 times his speed when running. It means his speed when biking would be
1.6 × x = 1.6x
Distance covered while riding would be
1.6x × 2.25 = 3.6x
He covered a total distance of 51 miles. Therefore,
1.5x + 3.6x = 51
5.1x = 51
x = 51/5.1 = 10 miles per hour.
His biking speed would be
1.6 × 10 = 16 miles per hour.
I don’t know I’m just doing this for the points I’m sorry ☮️✌️
Answer:
All real numbers
(-∞, ∞)
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We see here that our function is a parabola. We also see that we can plug in any number <em>x </em>and we would get an output <em>y</em>. Therefore, our domain is all real numbers:
(-∞, ∞)
