Ok so the formula is SA = 2(l)(w) + 2(l)(h) + 2(w)(h). Plug the numbers in. SA = 2(3)(9) + 2(3)(13) + 2(9)(13). Multiply the numbers; 2·3·9=54. 2·13·3=78. 2·9·13=234. Now you have SA= 54 + 78 + 234. Add them together and SA= 366mm²

SA = 2(wl+hl+hw)

SA = 2((3)(13) + (9)(13) + (9)(3))

Multiply:

SA = 2(39 + 117 + 27)

Add:

SA = 2(183)

Multiply:

SA = 366

The diagram shows a parallelogram.

emmasim [6.3K]

Answer:

27.44 square cm

Step-by-step explanation:

If the length of parallelogram is a and b and angle between side a and b is $\alpha$ .

Then area of parallelogram = $a*b*sin(\alpha ) = ab sin(\alpha )$

Given side length 4 cm and 7 cm

angle between them = 100°

value of sin(100°) = 0.98

Thus, area of given parallelogram = 4*7*sin(100°) = 28*0.98 = 27.44

Thus, area of given parallelogram is 27.44 square cm.

Solution:

Given that, Fred thinks of a number that is greater than 110 and less than 120

He can make his number with same number of hundreds,tens and ones

To find: Fred's number

Given that the number is greater than 110 and less than 120

The possible numbers are:

111 , 112, 113, 114, 115, 116, 117, 118, 119

But he can make his number with same number of hundreds,tens and ones

So the numbers in ones, tens and hundreds place are same

So the only possible number is 111

Thus the number Fred thinks of is 111

None, because you need to make over 15,000 a year to be taxed. And with all that money for one year would not be taxed.

Rita caught 5 fish. The lengths, in inches, of each tish are listed.

Aloiza [94]

Given:

The lengths, in inches, of each fish are listed:

9, 13, 9, 21, 18

To find:

The statement that best represents the meaning of the range for these data.

Solution:

The given data values are:

9, 13, 9, 21, 18

Arrange the data values in ascending order.

9, 9, 13, 18, 21

Here, the maximum value is 21 and the minimum value is 9.

We know that,

$\text{Range}=\text{Maximum value}-\text{Minimum value}$

$\text{Range}=21-9$

$\text{Range}=12$

The range of the data set is 12. Therefore, the difference between the shortest and longest fish is 12 inches.
