The answer is 6.72
What is area diagram method?The length and width of a rectangle are defined by the factors being multiplied in an area model, which is a rectangular diagram used in mathematics to solve multiplication problems. Therefore, the area of the rectangle is the product. Subsequently, it is known as the "Region model for augmentation".
Given (4.2) x (1.6)
by area drawing method make an rectangle of 4.2 and 1.6 units and make perpendicular lines at distance of 4 units and 1 units on length and breadth, the rest distance will be 0.6 and 0.2 units, now we have four different rectangles as shown in image now find area of each rectangle and add all the areas.
area of rectangle 1 = 4 x 1 = 4
area of rectangle 2 = 1 x 0.2 = 0.2
area of rectangle 3 = 4 x 0.6 = 2.4
area of rectangle 4 = 0.2 x 0.6 = 0.12
total area = 4 + 0.2 + 2.4 + 0.12
total area = 6.72
Hence (4.2) x (1.6) = 6.72

A factory robot recently examined some bulbs, of which 4 were flawed and 26 were not. Considering this data, how many flawed bulbs would the robot be expected to find in a batch of 15 bulbs?
Answers
Answer:
2
Step-by-step explanation:
Given that:
Flawed bulbs = 4
Not flawed = 26
Total examined = (flawed + not flawed)
Total examined = (4 + 26) = 30
P(flawed) = flawed / total
P(flawed) = 4 / 30 = 0.1333333
If 15 is examined :
Expected number of flawed bulbs :
(4/30) * 15 = 2

A -foot-long footbridge has two diagonal supports that meet in the center of the bridge. Each support makes a angle with a short vertical support.
Answers
Complete question :
A 25-foot-long footbridge has two diagonal supports that meet in the center of the bridge. Each support makes a 65∘ angle with a short vertical support.
What is the length x of a diagonal support, to the nearest tenth of a foot?
Answer:
13.80 feets
Step-by-step explanation:
Taking either of the triangles formed and attached to the picture, the length of diagonal, x can be obtained using Pythagoras rule :
To obtain x :
Sinθ = opposite / hypotenus
Opposite = 12.5 feets ; hypotenus = x ; θ = 65°
Sin 65 = 12.5 / x
0.9063077 * x = 12.5
x = 12.5 / 0.9063077
x = 13.792225
x = 13.80 feets

In ΔMNO, n = 92 inches, ∠N=119° and ∠O=20°. Find the length of m, to the nearest 10th of an inch.
Answers
Answer:
Step-by-step explanation:
The length of the side of the triangle will be 69 inches.
What is the sine law?The Law of Sines The law of trigonometric functions, sine law, sine formula, or sinusoidal rule is a trigonometric equation that relates the sizes of any triangle's edges to the sines of its orientations.
The sine law in the triangle ΔMNO is given as,
n / sin N = m / sin M = o / sin O
The third angle is calculated as,
∠M + ∠N + ∠O = 180°
∠M + 119° + 20° = 180°
∠M = 41°
The length m is calculated as,
n / sin N = m / sin M
92 / sin 119° = m / sin 41°
m = 69 inches
The length of the side of the triangle will be 69 inches.

(We move all terms to the left)
3x+4*2x-(11)=0
( We multiply elements )
3x+8x-11=0
(We add all the numbers together, and all the variables )
11x-11=0

11x=11
