Answer: 10

Step-by-step explanation:

I think it is 10 because they take 30 min. To do it together. Gertrude must take longer since she is the one who did 40 min. And if you subtract 40-30=10.

Again that’s what I think so... hope you get it right!

Answer:

120 hours

Step-by-step explanation:

Both take 30 minutes, meaning that in one minute they do  1/ 30 of the task

if Gertrude takes forty minutes then in one minute she does 1/40 of the task

To get the fraction that Bertha does in one hour we subtract the fraction that Gertrude does from the fraction they both do in one minute.

1/30-1/40=1/120

thus the number of hours taken is given by taking the reciprocal of 1/120

=120 hours

Answer:

∠ XZY ≈ 23.6°

Step-by-step explanation:

Using the sine ratio in the right triangle, that is

sinXZY = \frac{opposite}{hypotenuse} = \frac{XY}{YZ} = \frac{6}{15} , then

∠ XZY = sin^{-1} (\frac{6}{15} ) ≈ 23.6° ( to 1 dec. place )

If the length of a side of a square is x CM its perimeter is​
andreev551 [17]

Square perimeter =4x cm.

The complete length that a square's edge encompasses is referred to as its perimeter. Any enclosed geometric shape's perimeter may be computed by measuring the space around it.

By calculating the total of all the sides of a square, the perimeter may be determined. The perimeter of a square will be stated as,

The perimeter of square = s + s + s + s

⇒Perimeter of square = 4s, where "s" is the side length of the square.

This is because all edges of a square are equal and each edge measures "s" units.

<h3>Calculating the perimeter of a square:</h3>

Mathematically, the formula for calculating a square's perimeter is: Square perimeter, (P) = 4 Side

⇒P= 4x cm

It is concluded that the solution is 4x cm.
