Spent a lot of time in this, please rate brainiest?
Answer:
8
Step-by-step explanation:
10 minus 4 goes first because of BODMAS so thats 6
then 3 times 2 because again bodmas to thats 6
so then its 8 + 6 - 6
can be done in any order not affected by bodmas
6-6 cancels out so the answer is 8
comment if you want an in depth explanation on bodmas lol
Answer:
x = 28 cm
Step-by-step explanation:
Given:
Area of link shaded regions = 84 cm²
Required:
The value of x (diameter of the semicircle/length of the rectangle)
Solution:
Diameter of the semicircle = 2r = x
Length of rectangle (L) = 2r = x
Radius of semicircle (r) = ½x
Width of rectangle (W) = radius of semicircle = ½x
Use 3.14 as π
Area of the link shaded regions = area of rectangle - area of semicircle
Thus:
Area of the link shaded regions = (L*W) - (½*πr²)
Plug in the values
84 = (x*½x) - (½*3.14*(½x)²)
84 = x²/2 - (1.57*x²/4)
84 = x²(½ - 1.57/4)
84 = x²(0.5 - 0.3925)
84 = x²(0.1075)
Divide both sides by 0.1075
84/0.1075 = x²
781.4 = x²
√781.4 = x
27.9535329 = x
x = 28 cm

Answer:
Maxine is correct
Step-by-step explanation:
Given
last week= 15 hours
this week= 18 hour
Prove that hours this week is 120% than the hours last week
15 hours* 120%= 18 hours
18 hours/ 15 hours=1.20 x 100%= 120%
Maxine is correct. She spent 120% more time doing homework this week.
