Answer:
x > -5.25
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
A rate is a ratio where time is usually involved such as 60 km/ 1 hour.
So, the answer is true.
Your question is somewhat ambiguous.
If you want to solve this equation for y in terms of x, first multiply all of its terms by the LCD (which is 5), to remove the fractions.
5(3/5)x + 5(1.4y) = 5(2/5)
Then 3x + 7y = 2 This is the equation of the line in "standard form."
Next, subtract 3x from both sides: 7y = -3x + 2
Dividing by 7, y = (-3/7)x + (2/7)
This is the slope-intercept form of the given equation. It has a slope of -3/7 and a y-intercept of (0, 2/7).
The point-slope form of the same equation is
y- 2/7 = (-3/7)(x - 0), or -3x/7. y - 2/7 = (-3/7)x
Answer: ![A=530.66\ cm^2](https://tex.z-dn.net/?f=A%3D530.66%5C%20cm%5E2)
Step-by-step explanation:
For this exercise it is necessary to remember that the area of a circle can be calculated with the following formula:
![A=\pi r^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2)
Where "A" is the area of the circle and "r" is the radius of the circle.
In this case, based on the information given in the exercise, you know that the circular plate has the following radius:
![r=13\ cm](https://tex.z-dn.net/?f=r%3D13%5C%20cm)
Therefore, knowing the radius, you can substitute them into the formula and finally, you must evaluate in order to calculate the area of the plate (Remember that you must use 3.14 for
).
Then, you get that this is:
![A=\pi r^2\\\\A=(3.14)(13\ cm)^2\\\\A=530.66\ cm^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2%5C%5C%5C%5CA%3D%283.14%29%2813%5C%20cm%29%5E2%5C%5C%5C%5CA%3D530.66%5C%20cm%5E2)
