Answer:
Monthly fee is $50
Step-by-step explanation:
100 + 12x = 700
12x = 600
x = 50
100 being the initial fee, 12x being the monthly fee (as there is 12 months in a year).
The equation of the line that passes through (2, -1) and is parallel to a line that has a slope of 3/4 is: 3x - 4y = 10.
<h3>What is the Equation of a Line in Standard Form?</h3>
The equation of a line can be expressed as, Ax + By = C, which is in standard form.
Given:
- A point (a, b) = (2, -1)
- Slope (m) = 3/4.
Plug the values into the point-slope form, y - b = m(x - a):
y - (-1) = 3/4(x - 2)
y + 1 = 3/4(x - 2)
4(y + 1) = 3(x - 2)
4y + 4 = 3x - 6
4 = 3x - 6 - 4y
4 + 6 = 3x - 4y
10 = 3x - 4y
3x - 4y = 10
The equation in standard form is: 3x - 4y = 10.

Answer:
C: 56,72,52
Step-by-step explanation:
we know that
An acute triangle is a triangle with three angles less than 90°
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
<u><em>Verify each case</em></u>
case A) The three measures are less than 90 degrees but the sum is not equal to 180 degrees (is not a triangle)
case B) The three measures are not less than 90 degrees
case C) The three measures represent an acute triangle ( the three measures are less than 90 degrees and the sum is equal to 180 degrees)
case D) The three measures are not less than 90 degrees. This triangle represent a right triangle
Answer:
99.38
Step-by-step explanation:
the area of all the circles by using the formula A=ℼr2 then filling in r with 3.2 A=ℼ3.22=32.2
Knowing that one circle is 32.2 4 circles would have an area of 128.8
Two circles have a combined length and height of 12.8 because the circumference of one circle is 6.4 so two circles reach the sides of the square. So all the sides of the square are 12.8. So finding the area of the square knowing what the sides are, so the area is a=163.84. To find the shaded area you subtract the volume of the square to volume of all 4 circles which is 163.84-128.8 which equals 35.04. Then you find the volume of the semi circle which is 64.34. Then the combination of both shaded regions is 99.38
