Zoe counts 5 times as many black kittens as white kittens for sale at the pet store. she counts a total of 25 kittens how many m
malfutka [58]

Let us say that:

a = black kittens

b = white kittens

 

We know that:

a = 5 b

a + b = 25

 

Therefore:

5 b + b = 25

6 b = 25

b = 4.17

But we cannot have a fraction value for the number of kittens, so round off:

b = 4

 

So a is:

a = 25 – 4 = 21

 

<span>Hence Zoe counts additional 1 black kitten.</span>

Why does a calculator return an error when trying to find inverse sine of 1.055?
Rashid [163]
The calculator returns an error as the answer for the inverse sine of 1.055 because the acceptable range for sine is only from 0 to 1.00 in which 1.055 is clearly greater than. This is also the same as for the cosine values.

What is the maximum height of of Anna's golf ball? The equation is y=x−0.04x2.
elena-s [515]

Given:

The height of a golf ball is represented by the equation:

y=x-0.04x^2

To find:

The maximum height of of Anna's golf ball.

Solution:

We have,

y=x-0.04x^2

Differentiate with respect to x.

y'=1-0.04(2x)

y'=1-0.08x

For critical values, y'=0.

1-0.08x=0

-0.08x=-1

x=\dfrac{-1}{-0.08}

x=12.5

Differentiate y' with respect to x.

y''=(0)-0.08(1)

y''=-0.08

Since double derivative is negative, the function is maximum at  x=12.5.

Substitute x=12.5 in the given equation to get the maximum height.

y=(12.5)-0.04(12.5)^2

y=12.5-0.04(156.25)

y=12.5-6.25

y=6.25

Therefore, the maximum height of of Anna's golf ball is 6.25 units.

How can i get the answer to 5 X 70 = 5 X ____ tens = ____ tens = _____
Maru [420]
Multiple 5x70 to get 350. Which makes the equation 350=5x and then you have to divide both sides by 5 to get x by itself.  so 5x/5 and 350/5 makes x=70
