In a school egg drop challenge 136 of the eggs broke out of 200 total what percent of eggs survived the drop ?

dusya [7]

To make this equation easier, we can just divide the data by 2, so that the exact number of eggs that survived, is the percentage that survived.

Explanation:

200 = 200 Total Eggs

136 = 136 Eggs That Broke

So, the ratio of eggs that broke to total eggs is:

136 / 200

So, subtract the number of eggs that broke to the total eggs, to find the amount that survived.

200 - 136 = 64

So now we know that, 64 eggs of 200 survived.

Which means, that 32% off the eggs had survived.

The graph above is the graph of: y = | x + 4 | − 2 y = | x − 4 | − 2 y = | x − 2 | − 4

Liono4ka [1.6K]

We need to identify the equation of the graph given.

This graph corresponds to a translation of the graph described as:

$y=|x|$

Comparing the graph given with the one above, we can see it was shifted 4 units to the left.

When we translate the graph of a function f(x) d units to the left, it is transformed as:

$f(x)\rightarrow f(x+d)$

The radius of a cylindrical vessel is 7 cm and height is 1400 m . Find the cost of painting its inner curved surface area at the

Olegator [25]

Answer:

Cost = 616000 DHS per square centimetre.

Step-by-step explanation:

curved surface of a cylinder = 2 $\pi$ rh

r = 7 cm

h = 1400 m = 140000 cm

The outer curved surface area of the cylinder = inner curved surface area of the cylinder

The inner curved surface of the cylinder = 2 $\pi$ rh

= 2 x $\frac{22}{7}$ x 7 x 140000

= 2 x 22 x 1 x 140000

= 6160000

The inner curved surface of the cylinder is 6160000 square centimetre.

But, the cost of painting is at the rate of 10 DHS per square centimetre.

The inner curved surface of the cylinder = 6.16 x $10^{6}$ square centimetre.

cost of painting the inner curved surface area = $\frac{6.16*10^{6} }{10}$

= 616000 DHS per square centimetre

The cost of painting the inner surface is 616000 DHS per square centimetre.
