The right answer for the question that is being asked and shown above is that:

This can be answered using the Pythagorean Theorem.
h2 = a2 + b2
h = square root (8^2 + 5^2)
h = <span>square root (64 + 25)
h = </span><span>square root (89) in
h = 9.4 in

So the correct answer is 9.4 in given the dimension 5 inches and 8 inches.</span>

joey's mom baked two dozen cookies . that night, there were only 14 cookies left. what percentage of the cookies were eaten?

Aleksandr [31]

Answer:

41.67 % ( to 2 dec. places )

Step-by-step explanation:

Since 2 dozen cookies were baked, that is 24 and 14 were left.

Then 10 were eaten.

Calculate the percentage eaten as

percentage = $\frac{numbereaten}{original}$ × 100%

percentage eaten = $\frac{10}{24}$ × 100% ≈41.67%

Alexa is researching a cure for the coronavirus. She needs 14 test tubes for 4 experiments. The first experiment requires 2 test

grigory [225]

Answer:

She used 4 test tubes for the last experiment

Step-by-step explanation:

Total test tubes needed = 14

Experiment 1 = 2 test tubes

Total test tubes remaining = total - used

= 14 - 2

= 12 test tubes

Remaining experiment = 4 - 1

= 3

Test tubes used for the remaining experiment = test tubes remaining / Experiment remaining

= 12 / 3

= 4 test tubes

How many test tubes did she use for the last experiment?

She used 4 test tubes for the last experiment

Help please anyone???

Answer:

x^2/1 +y^2/81 = 1

Step-by-step explanation:

We know that the equation of a unit circle is ...

x^2 +y^2 = 1 . . . . . equation of a unit circle

We also know that replacing x with x/a in a function will expand the graph by a factor of 'a'. Similarly, replacing y with y/b will do the same in the vertical direction.

An ellipse is a circle that has had different expansion factors applied along its different axes. Here, the given points tell us the center of the ellipse is (0, 0), and that it has been expanded by a factor of 9 in the y-direction and a factor of 1 in the x-direction This means the equation for it would be ...

(x/1)^2 +(y/9)^2 = 1 . . . . . equation for desired ellipse

In the required form, this is ...

$\dfrac{x^2}{1}+\dfrac{y^2}{81}=1$
