(2x + 26) = 180 degrees
2x + 26 = 180
2x = 154
x = 77
x = 77
2x + 26 = 180
2x = 154
x = 77
x = 77
−0.2x + 1.2 < 1.1
Subtract 1.2 from both sides:
-0.2x < -0.1
Divide by -0.2 (note that dividing by a negative number reverses the inequality sign):
x > -0.1 / -0.2
x > 0.5
Therefore, the solution to the inequality is x > 0.5.
Given:
Total saved = $5000
Amount spent on travel and lodging = $25
Amount spent on meals = 14% of the remaining amount after travel and lodging
First, calculate the total amount spent on travel and lodging:
$25
Subtract the amount spent on travel and lodging from the total saved:
$5000 - $25 = $4975
Calculate the amount for meals, which is 14% of $4975:
$4975 * 0.14 = $696.50
Therefore, Ginger and her friends will have to spend $696.50 on meals.
Since this is not an exact match to the provided response options, I recommend rounding to the nearest whole dollar, which in this case would be $697.
Therefore, the closest response option is:
$750
To find the lateral surface area of a cylinder, you need to calculate the height multiplied by the circumference of the base.
Given:
Diameter of the base = 5 inches
Radius (r) = diameter / 2 = 5 / 2 = 2.5 inches
Height (h) = 7.5 inches
Radius = 2.5 inches
The height of the cylinder forms the length of the lateral side, and the circumference of the base forms the width of the lateral side.
Circumference of base = 2 * π * radius
Circumference = 2 * 3.14 * 2.5 = 15.7 inches
Lateral surface area = Height * Circumference
Lateral surface area = 7.5 * 15.7
Lateral surface area = 117.75 square inches
Rounded to the nearest tenth, the lateral surface area of the cylinder is approximately 117.8 square inches.
Therefore, the correct response option is:
117.8 square inches.
Volume = Area of the base * Height
Given that the figure is a triangular prism, the base is a triangle. The formula for the area of a triangle is:
Area of a triangle = 1/2 * base * height
Given:
Base of the triangle = 12 inches
Height of the triangle = 10 inches
Height of the prism (perpendicular to the base) = 8 inches
First, calculate the area of the triangle (base * height * 0.5):
Area of triangle = 0.5 * 12 * 10
Area of triangle = 60 square inches
Then, calculate the volume of the triangular prism (area of the base * height of the prism):
Volume = 60 * 8
Volume = 480 cubic inches
Therefore, the correct volume of the triangular prism is 480 cubic inches.
Among the given responses, the closest option is:
240 in3
The most appropriate choice based on the calculation would be 480 in3, if all options are considered.
