Hernan cuts a board that is 7/10 of a meter long After the cut the board is 3/10 of a meter long how long is the piece that he c

Darina [25.2K]

Given that original lenght of the board before cut $= \frac{7}{10}$ meter

Lenght of the board that is left after cutting from the original piece by Hernan $= \frac{3}{10}$ meter

Now we have to find the lenght of the piece which is cut.

To find that we just need to subtract smaller piece from larger piece

Required Length $= \frac{7}{10}-\frac{3}{10}$ meter

Required Length $= \frac{7-3}{10}$ meter

Required Length $= \frac{4}{10}$ meter

reduce the fraction

Required Length $= \frac{2}{5}$ meter

Hence final answer is $\frac{2}{5}$ meter.

Need answers for 70-75

adoni [48]

Answer:

70. 0

71. -54

72. 12

73. 86

74. 59

Step-by-step explanation:

To evaluate an expression, substitute specific values for the variables and simplify using Order of Operations.

70. c-3d becomes

$(1)-3(\frac{1}{3}) = 1-(\frac{3}{3}) = 1-1 = 0$

71. $x+x^3-4x^4$ becomes

$2+2^3-4(2)^4 = 2+8-4(16) = 2+8-64=10-64=-54$

72. $5a+3a^2$ becomes

$5(-3)+3(-3)^2 = -15 +3(9) = -15 + 27 = 12$

73. $F=\frac{9}{5}C+32$ becomes

$F=\frac{9}{5}(30)+32=\frac{270}{5}+32 = 54+32 = 86$

74. $F=\frac{9}{5}C+32$ becomes

$F=\frac{9}{5}(15)+32=\frac{135}{5}+32 = 27+32 = 59$

Answer:

x = 8

Step-by-step explanation:

By AA similarity, ΔABD ~ ΔCDE. So, corresponding sides are proportional.

AB/BD = CD/DE

x/12 = 4/6

x = 12(4/6)

x = 8
