Answer:

100 square cm

Step-by-step explanation:

Area of figure 1 = l *b = 10 *7 = 70 square cm

Area of figure 2 = 6* 5 = 30 square cm

Area of shape = 70 + 30 = 100 square cm

The sum of 1/6, 2/3, and 1/4 is

Verdich [7]

Sum indicates addition - you must add these fractions together. To add fractions, they must have a common denominator. The least common multiple of 6, 3, and 4 is 12. Multiply the fractions as follows to get a common denominator of 12.

1/6 × 2/2 = 2/12

2/3 × 4/4 = 8/12

1/4 × 3/3 = 3/12

Add the fractions (add their numerators).

2/12 + 8/12 + 3/12 = 13/12

Answer:

$\frac{13}{12}$ or $1\frac{1}{12}$

Apply the distributive property to factor out the greatest common factor.

podryga [215]

Answer:

12 + 20 = 4(3 + 5)

Step-by-step explanation:

The distributive property is ab + ac = a(b + c), where

a is the greatest common factor of the two terms ab and ac

Let us solve the question

∵ 12 = 1 × 12, 2 × 6, 3 × 4

∴ The factors of 12 are 1, 2, 3, 4, 6, 12

∵ 20 = 1 × 20, 2 × 10, 4 × 5

∴ The factors of 20 are 1, 2, 4, 5, 10, 20

→ Find their common factors

∵ The common factors of 12 and 20 are 1, 2, 4

∴ The greatest common factor of 12 and 20 is 4

∵ 12 ÷ 4 = 3

∵ 20 ÷ 4 = 5

∴ 12 + 20 = 4 × 3 + 4 × 5

→ Take 4 as a common factor

∴ 12 + 20 = 4(3 + 5)

The possible error involved in measuring each dimension of a rectangular box is ±0.02 inches. The dimensions of the box are 8 in

Vlad [161]

Answer:

Step-by-step explanation:

Given

Possible dimension error is $\pm 0.02 in.$

length of box $L=8 in.$

Width $W=5 in.$

height $h=12 in.$

Volume V is given by

$V=LWh$

$dV=LWdh+LhdW+WhdL$

and it is given

$dL=dW=dh=\pm 0.02\ in.$

since error always add therefore

$dV=(8\times 5+5\times 12+8\times 12)\cdot 0.02$

$dV=3.92 in.^3$

Propagated error is $3.92 in.^3$

relative error $=\frac{dV}{V}$

$=\frac{3.92}{480}$

$=0.00816$

$=0.816 \%$
