Answer:
It does not make a right triangle
Step-by-step explanation:
To know if these measurements make a right triangle, let's square all values,
15² = 225
20² = 400
24² = 576
Looking at these values, no two values add up that would be equal to one of the values.
Therefore, it does not make a right triangle.
The y-intercept is the point where a line or curve intersects the y-axis; in other words, it's the point on the function where x = 0. If we want to find the y-intercept for the first function x + 4y = 8, we can replace x with 0 and solve for y:
0 + 4y = 8
4y = 8
y = 2
So, the y-intercept for the first function, and therefore the y-intercept for the second function, is (0, 2)
4*0.23
0.92
the answer is 0.92
Answer:
P = (21.4a+36.6) cm
Step-by-step explanation:
Given that,
The width of a rectangle, b = (6.9a+8.5) cm
The length of a rectangle, l = (3.8a+9.8) cm
We need to find the perimeter of the rectangle. Perimeter is the sum of all sides. So,
P = 2(l+b)
Put all the values,
P = 2(6.9a+8.5+3.8a+9.8)
= 2(6.9a+3.8a+8.5+9.8)
= 2(10.7
a+18.3)
= (21.4a+36.6)
So, the perimeter of the rectangle is (21.4a+36.6) cm.
Answer:
5.5 Hours
Step-by-step explanation:
Currently, the equation is 60=8.50h+13.25 and h stands for the hours that Sammie worked. So, you need to solve for h by first subtracting 13.25 (his tips) and getting the amount that he received for the hours that he worked.
You should now have 46.75=8.50h
Our final step, is to divide 46.75 by 8.50 to get h by itself and determine the total hours that Sammie worked.
In the end, you should come out with h=5.5, which means that Sammie worked 5.5 hours.
