The actual length of side t is 0.045 cm. Use the scale drawing to find the actual side length of w. A) 0.06 cm B) 0.075 cm C) 0.

Tems11 [23]

Answer: The answer is B 0.075 cm

Step-by-step explanation:

Since the drawings is a scale of the original you must use a proportion to solve the desired side. 0.045/.9=w/1.5;w=0.075.

Sum of two numbers is -17. Their difference is 41. Find the numbers

wel

Answer:

$Suppose~the~two~numbers~are~x~and~y.\\From~the~first~condition,\\x+y=-17...........(1)\\From~the~second~condition,\\x-y=41.............(2)\\Adding~eq^n(1)~and~eq^n(2),~we~get,\\x+y+x-y=-17+41\\or, 2x = 24\\or, x=12\\Substituting~x=12~in~eq^n(2),\\y = -17-x = -17-12 = -29$

$So,~the~two~numbers~are~12~and~-29.$

the volume of a solid triangular prism is 726 cubic centimeters. its height is 12 centimeters and its bases are congruent right

aivan3 [116]

9514 1404 393

Answer:

11 cm

Step-by-step explanation:

The volume of the prism is given by the formula ...

V = Bh

where B is the area of the triangular base, and h is the height.

Filling in the given information, we find the area of the triangular base to be ...

726 cm³ = B(12 cm)

B = 726 cm³/(12 cm) = 60.5 cm²

The area of an isosceles right triangle is half the area of a square with the same side lengths:

B = 1/2s²

60.5 = 1/2s²

s = √(2(60.5)) = √121 = 11

The length of each of the equal sides of the base is 11 cm.
