Answer:

The surface area of the cuboid is 648 m^2

Step-by-step explanation:

What we have here is cuboidal in outlook

By using the formula for the surface area of a cuboid, we can get the surface area of the shape

mathematically, we have the surface area of a cuboid as follows;

2(lb + lh + bh)

where l is the length, b is the breadth (width) and h is the height

We can have the length as 9 m, the width as 9 m and the height as 13.5 m

Substituting these values, we have the surface area of the cuboid as;

A = 2(9(9) + 9(13.5) + 9(13.5))

A = 2(81 + 243)

A= 2(324)

A = 648 m^2

I'm guessing the total amount of degrees is 360 degrees.

67 + 130 + 72 = 269

360 - 269 = 91

Answer = 91°

a ladder 13m long is placed on the ground in such a way that it touches the top of a vertical wall 12m high. find the distance o
Sergio039 [100]

Answer:

by applying Pythagoras theorem;

the ladder(13m) acts as hypotenuse

the wall (12m) acts as height

the distance between the the two is the base

therefore

a² + b² = c²

b²= c²- a²

b²= 169 - 144

b² = 25

√b² = √25

b= 5m

the distance is 5m

22 random samples were selected from a population that has a normal distribution the sample has a mean of 99 and a standard devi
olga2289 [7]

Answer:

(96.91, 101.09)

Step-by-step explanation:

To calculate the interval, you require the Z value at 95% confidence interval. The Z value is 1.96. The formula to calculate the confidence interval:

X-Zs/\sqrt{x} \\X+Zs/\sqrt{x}

Where X is the mean and s is the standard deviation and x the sample size:

99-1.96\cdot{5}/\sqrt{22} \\99+1.96\cdot{5}/\sqrt{22}

The interval is (96.91, 101.09)

alekssr [168]
The problem is modelled as right angle triangle, shown in the diagram below

The distance between the pilot and the house is labelled as x

Using the trigonometry ratio of sine
sin(31)= \frac{opposite}{hypotenuse}
sin(31)= \frac{2010}{x}
x= \frac{2101}{sin(31)} = 4079.3 ft
