Answer:
6. 8 mi³
7. 72 cm³
Step-by-step explanation:
6. Volume of triangular pyramid = ⅓*A*H
Where,
A = area of triangular base = ½*b*h = ½*3*4 = 6 mi
H = height of pyramid 4 mi
Volume = ⅓*6*4 = 8 mi³
7. Volume of triangular prism = ½*bhl
Where,
b = 3 cm
h = 6 cm
l = 8 cm
Volume = ½*3*6*8 = 72 cm³
I am assuming when you write 27x5 u mean "27 times x to the power of 5".
therefore, your answer is 9x3-11x2-7x
Answer:
R___S___T
RT=RS+ST
(17y-33) =( 9y+3)+(3y+4)
17y-33 = 12y+ 7
17y - 12y = 7+33
5y= 40
y=40/5
y= 8
RS = 9y+3 = 9(8)+3= 72+3=75
ST= 3y+4 = 3(8)+4=24+4=28
RT= 17y-33= 17(8)-33= 136-33= 103 —>
<u>Or</u><u> </u><u>;</u> RT=RS+ST =75+28= 103
<h3><u>So</u><u>;</u></h3><h3>a. <u>Ans;</u> y=8</h3>
<h3>b. <u>Ans;</u> RS= 75 , ST = 28 , RT = 103</h3>
I hope I helped you^_^
The answer is true because 8 times 125 (8x125) is equal to 1000 therefore Tiara is correct
Answer:
