Mathematics
1 answer:
kogti [31]3 years ago
7 0

Answer:

In both cases, we have similar figures.

This means that the shape of the figures is the same, but the size is different:

PQST is similar to STNR and to NRPQ

VUYZ is similar to YZWX and to VUWX

this means that, for example, in problem 18, the ratio between ST and NR must be the same as the ratio between PQ and ST. This happens because the measure increases by the same scale factor.

With this in mind, we can solve the problem:

18)

ST = 7.5

NR = 5.5

Then the quotient ST/NR is:

ST/NR = 7.5/5.5

And, as we said above:

PQ/ST = ST/NR

PQ/7.5 = 7.5/5.5

PQ = (7.5/5.5)*7.5 = 10.23

19) Here we should have:

YZ/VU = WX/YZ

Then:

22.9/35 = WX/22.9

(22.9/35)*22.9 = WX = 14.98

beks73 [17]

Answer:

The answer is 13 1/6

Step-by-step explanation:

The answer is 18 because 7 1/3 turns into 7 2/6 and 7 * 6 is 42 and 42 plus 2 is 44. Next You turn 5 5/6 into a improper fraction which turns into 35/6 and 35 plus 44 is 79/6 and 79/6 simplified is 13 1/6

Find the surface area of the composite solid.
kicyunya [14]
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
