Answer:
4. Circumference = diameter × π
8× 3. 14= 25. 12 ~25. 1
5. 13×3. 14= 40. 82 ~40. 8
6. Diameter= radius ×2
3. 5×2=7
Diameter = 7
7× 3. 14= 21. 98 ~22
Answer:
He pays $39.56
Step-by-step explanation:
If finding the discount, always divide the percent by 100.
25% = 0.25
52.75*0.25=13.1875
Because its money, round to hundredths place, $13.19
Subtract the "percent" (13.19) from 52.75
52.75 - 13.19 = $39.56
136×25%=136×25/100= 3 400/100=34
so the markeup value is
136+34= 170
170×17%=170×17/100=2 890/100=28.9
170-28.9=141.1
Selling price=136+170=306
Area of a triangle is half multiplied by the height multiplied by the base.So multiplying the two together and halfing is shown below
Bear in mind that, when it comes to trigonometric functions, the location of the exponent can be a bit misleading, however recall that sin²(θ) is really [ sin( θ )]²,
