I'm not sure what your asking, but if your asking how long it took her, it took her one hour. There is 12 boxes, and each one took her 5 minutes. 12*5 is equal to 60.

Tarush is a landscape architect. For his first public project he is asked to create a small scale drawing of a garden to be plac
Lunna [17]

Answer:

See the attached figure 2.

Step-by-step explanation:

The question is as shown at the attached figure 1.

given: The garden is a right triangle with base 10 m and height 15 m.

We need to draw the garden such that 1 unit on the grid represents 2 m.

So the scale factor is 1 unit = 2 m

base = 10 m = 10/2 = 5 units

height = 15 m = 15/2 = 7.5 units

So, the garden on the grid will be a right triangle with base 5 units  and height 7.5 units.

See the attached figure.

An expression is given: 2 open parentheses square root of k minus 1 close parenthesis plus square root of 8. If on adding negati
neonofarm [45]

Answer:

Possible value of k is √2

Step-by-step explanation:

The information given are;

The expression, 2·(√k - 1) + √8 to which may be added -6·√2 to obtain a rational number, we therefore have;

2·(√k - 1) + √8 - 6·√2 = R

Therefore, simplifying gives;

2·√k - 2 + 2·√2  - 6·√2 =  2·√k - 2 - 4·√2 = R

2·√k - 2 - 4·√2 + 2= R + 2 = R

2·√k - 2+ 2 - 4·√2 = R

2·√k - 2+ 2 - 4·√2 = R

2·√k + 0 - 4·√2 = 2·√k - 4·√2 = 2·(√k - 2·√2) = R

(√k - 2·√2) = R/2 = R

Therefore, √2 is a factor of √k such that √k - 2·√2 = R

Which gives k = x·√2, where x = a rational number

When x = 1, k = √2.

Therefore, a possible value of k is √2

A baby wriggled so much that weighing him at the clinic was a problem. So the doctor held the baby and stood on a scale. Then th
Pepsi [2]
X = <span>weight of the baby.
y = </span>weight of the doctor.
z = weight of the nurse.

x + y = 78 so y = 78 - x
x + z = 69 so z = 69 - x
x + y + z = 142

substitute y = 78 - x and z = 69 - x into x + y + z = 142

x + y + z = 142
x +78 - x + 69 - x = 142
-x + 147 = 142
-x = - 5
 x = 5

answer

<span>the weight of the baby was 5 kg</span>
