Answer:
Step-by-step explanation:
In exponent multiplication, if the bases are same then add the exponents.
Area of the bottom triangle = 1/2 x 10 x 8.7 = 43.5 cm²
Area of the 3 rectangles = 3(10 x 6) = 180 cm²
Area of the top triangle = 3 (1/2 x10 x 4) = 60 cm²
Total surface are = 43.5 + 180 + 60 = 283.5 cm²
Answer: 283.5 cm²
Answer:
x = 4
Step-by-step explanation:
A midpoint divides the segment into two equal parts. Each is half the length of the whole.
XY = (1/2)XZ
5x+4 = (1/2)(8x +16)
5x +4 = 4x +8
x = 4 . . . . . . . . . subtract 4x+4 from both sides
_____
<em>Check</em>
5x+4 = 5(4)+4 = 24
8x+16 = 8(4) +16 = 48
So, XY is half of XZ.
Answer:
Step-by-step explanation:
Sammie is x,,,, Jennie is 9 years younger than him. So, Jennie ( y) = x-9
According to second condition eq is
(X-5) = 4(y-5)
Place the value of y in eq 2
You will find x= 17
Put x in eq 1
Y = 8
Yes!
1/4 will equal 3/12
2/3 will equal 8/12
