Answer:
(3250/100)*80 = $ 2600 - 3250 = $650
Step-by-step explanation:
Answer:
745.4 cm^2
Step-by-step explanation:
The composite figure is made up of a rectangle 25 cm by 20 cm and a semicircle of radius 12.5 cm.
We add the two areas to find the total area.
total area = area of rectangle + area of semicircle
TA = LW + (1/2)(pi)r^2
TA = (25 cm)(20 cm) + (1/2)(3.14159)(12.5 cm)^2
TA = 500 cm^2 + 245.4 cm^2
TA = 745.4 cm^2
Follow PEMDAS:
First, distribute 3 to all terms within the parenthesis
3(4x) = 12x
3(5) = 15
12x + 15 + 2
Simplify. Combine like terms
12x + (15 + 2)
12x + 17
12x + 17 is your answer

Answer: Angle C = 51.5°
Step-by-step explanation:
The diagram of the triangle is shown in the attached photo.
we would apply the law of Cosines which is expressed as
c² = a² + b² - 2bcCosC
Where a,b and c are the length of each side of the triangle and C is the angle corresponding to c.
Therefore,
18² = 23² + 14² - 2(23 × 14)CosC
324 = 529 + 196 - 2(322)CosC
324 = 725 - 644CosC
644CosC = 725 - 324
644CosC = 401
CosC = 401/644
CosC = 0.623
C = Cos^- 1(0.623)
C = 51.5° to the nearest tenth
