-8/7 is the correct answer.
Answer: x = 27
Step-by-step explanation:
2x+3x+45=180º because all of the angles of a triangle add up to 180
5x=180-45
5x=135
x=135/5
x=27
Answer:
d = 16.88
Step-by-step explanation:
Start by simplifying both sides of the equation then isolate the variable
Answer:
the lateral area of the regular prism is 30 cm².
Step-by-step explanation:
Given;
the base of the regular prism, b 4cm
height of the prism, h = 2.5 cm
The lateral area of the regular prism is calculated as the product of the base perimeter and height of the prism.
L.A = P x h
where;
P is the perimeter of the base = 3 x 4cm (equilateral triangle has equal sides)
P = 12 cm
L.A = 12 cm x 2.5 cm
L.A = 30 cm²
Therefore, the lateral area of the regular prism is 30 cm².
100%=9.99
×%=6.75
9.99x=100×6.75
9.99X=675
X=675/9.99
67.567% or 67.57
you could also say:
6.75/9.99=0.67567
0.67567×100=67.57%
so the markup is 100%-67.57%=32.43%
32.43%off
