A rectangular block is 16cm long, 12cm broad and 5cm high. find its total surface area and volume​

Answers

Answer 1

Answer:

volume is l×b×h.

thats 16*12*5 that is 960cm cubed.

total surface area is 2(l×b+b×h+h×l).

that's 2(16×12+12×5+16×5).

664 cm squared .

Answer 2

Answer:

surface area=2(lb+bh+hl)

surface area=2(16×12+12×5+5×16)

surface area=664cm²

volume = 16cm×12cm×5cm

volume= 960cm³

Answer:

70

Step-by-step explanation: Triangle angle sum theorem states the interior angles of a triangle sum to 180 degrees. We know one angle is 40 degrees and the two remaining angles are equal in measure.

Since angle J and angle L are equal in measure we can substitute 2x for angles J and L into the equation.

40 + 2x = 180. Subtract 40 from both sides.

2x = 140. Divide both sides by 2.

X = 70

Answer:

The area of the shape is 21.87 square feet.

Step-by-step explanation:

Assuming the indent on the right is a perfect semicircle, then you need only subtract the area of the semicircle from the area of the rectangle.

The rectangle is six feet on both directions, giving it an area of 36 square feet.

The circle then has a radius of 3 feet.  The area of a circle is equal to πr², so in this case, π × 9.  Using a pi value of 3.14, nine times that is 28.26.  We only want half the circle's area though, giving us 14.13.

Now we can subtract that semicircle from the square giving us:

36 - 14.13 = 21.87

So the total area is 21.87 square feet.

y=-x/3+2

Step-by-step explanation:

If you graph out 3x-y-7=0, you will get a line that goes through the points (0, -7), and about (2.3, 0). If you graph out y=x/3+2, you have to make sure that this line forms a 90 degree angle on the previous line, thus making this line perpendicular to the previous line.

An apartment manager would like to survey a sample of residents to determine whether there may be interest in building a pool what is the best way that the apartment manager could select he sanple

Answers

Answer: b. randomly select people from all residents of the apartment building.

Step-by-step explanation:

This issue at hand concerns all residents of the building so the apartment manager should randomly select people to participate in the survey from the entire population of all the residents of the apartment building.

Selecting only those who have children would not be representative of the whole population as there will be people with less or more children than 5 and some would not have children. Option C and D are wrong because only current residents should be included.

There are 107 coins in a jar, all dimes and nickels. The coins are worth $6.70. How many of each kind of
coin is in the jar?

Answers

d = number of dimes

n = number of nickels

The jar contains a total of 107 coins, so

d + n = 107

Each dime is worth $0.10 and each nickel is worth $0.05, and the jar contains a total value of $6.70, so

0.10d + 0.05n = 6.70

Multiply both sides of the second equation by 100 to eliminate the decimal points:

10d + 5n = 670

Multiply both sides of the first equation by -5:

-5d - 5n = -535

Add the corresponding sides of these two equations to eliminate n and solve for d :

(10d + 5n) + (-5d - 5n) = 670 + (-535)

(10 - 5)d + (5 - 5)n = 670 - 535

5d = 135

d = 135/5 = 27

Then

n = 107 - d = 80

so the jar contains 27 dimes and 80 nickels.

Explain why this common mistake is wrong. Many people might say that (2, 4) is an intercept of the equation 5x + 2y = 18.

Answers

Answer:

Step-by-step explanation:

(2,4) is point lying on the line represented by 5x + 2y  = 18.

They are not intercepts.

x-intercept is point where the line crosses the x-axis and so, y-co ordinate at x-intercept is 0.

y-intercept is point where the line crosses they-axis and so,x-co ordinate at y-intercept is 0.

5x + 2y = 18

To find x-intercept, put y = 0 in the equation

           5x = 18

             x = 18/5

             x = 3.6

To find y-intercept, put x = 0 in the equation

          2y = 18

             y = 18/2

             y = 9

x-intercept : (3.6 , 0)

y-intercept :(0, 9)
