Answer:

HCF: 20

LCM: 300

Step-by-step explanation:

This is a simpler and easier way to answer this question. Refer to the picture.

Put the numbers (two or more numbers) side-by-side, then find a common factor. Put the factor on the right (2 in this case) and divide both numbers by the factor, then put the quotients below their respective dividends. Keep going until there are no more common factors. Then, for the HCF, use only the number on the left (i.e. 2, 2, and 5). Multiply them to get the HCF. 2*2*5=20

For the LCM, multiply the numbers on the left and the bottom, i.e. 2*2*5*5*3 = 300

$100 = 2 \times 2 \times 5 \times 5 \\ 60 = 2 \times 2 \times 3 \times 5 \\ hcf = 2 \times 2 \times 5 = 20 \\ lcm = 2 \times 2 \times 5 \times 3 \times 5 = 300$

Answer:

1) 12

2) c=-25

3) x = -16 2/3

Step-by-step explanation:

1) ..........................

6*(4-10+8) =
6*(- 6+8) =
6*2=
12

2) ..........................

34 + 2c = -16
2c = - 16 -34
2c = -50
c = -50/2
c=-25

3) ..........................

40 = -3x - 10
40+ 10 = -3x
-3x = 50
x = 50/-3
x=-16 2/3

Borland, Inc., has a profit margin of 5.6 percent on sales of $13.6 million. If the firm has debt of $6.4 million and total asse

aniked [119]

Answer:

ROA = 7.77 percent

Step-by-step explanation:

Borland, Inc., has a profit margin of 5.6 percent on sales of $13.6 million

Thus, profit = 5.6% of $13.6 million

profit = 5.6 / 100 * $13.6 million = $0.7616 million

Profit is same as net income

Formula for ROA (return on asset) = net income/ total asset

total asset as given = $9.8 million

Thus, ROA = $0.7616/ $9.8 = 0.0777

ROA in percentage = 0.0777*100 = 7.77

Thus, ROA is 7.77 percent .

A family wants to build a rectangular garden on one side of a barn. If 600 feet of fencing is available to use, then what is the

vovangra [49]

Answer: (A) $A=300l-l^{2}$

(B) Length varies between 1 and 150

Step-by-step explanation: Suppose length is l and width is w.

The rectangular garden has perimeter of 600ft, which is mathematically represented as

$2l+2w=600$

Area of a rectangle is calculated as

$A=lw$

Now, we have a system of equations:

$2l+2w=600$

$A=lw$

Isolate w, so we have l:

$2w=600-2l$

w = 300 - l

Substitute in the area equation:

A = l(300 - l)

A = 300l - l²

(A) Function of area in terms of length is given by A = 300l - l²

(B) The practical domain for this function is values between 1 and 150.

(C) For the largest area, we need to determine the largest garden possible. For that, we take first derivative of the function:

A' = 300 - 2l

Find the values of l when A'=0:

300 - 2l = 0

2l = 300

l = 150

Replace l in the equation:

w = 300 - 150

w = 150

Now, calculate the largest area:

A = 150*150

A = 22500

The largest area the fence can enclose is 22500ft².
