Which shows 0.00234 written in scientific notation?

topjm [15]

It’s D

the reason why is because the multiplier must be between 1 and 10
(
1
≤
x
≤
10
)
so first more your decimal there which you get:
2.34
then just count how many numbers the decimal jumped, if the decimal moved left the exponent is positive and if it moved right, as in your number, the exponent is negative

yours moved 3

A rectangular swimming pool measures 14 feet by 30 feet. The pool is

Zolol [24]

Answer:

The total cost of resurface the path is $\$600$

Step-by-step explanation:

step 1

Find the area of the path

The area of the path is equal to the area of the path plus the swimming pool minus the area of the swimming pool

$A=(14+3+3)(30+3+3)-(14)(30)$

$A=(20)(36)-(14)(30)$

$A=300\ ft^{2}$

step 2

Find the cost of resurface the path

Multiply the area of the path by $2 per square foot

$300*2=\$600$

A pilot and co-pilot are performing a test run in a new airplane. The pilot is required to take off and fly in a straight path a

crimeas [40]

Using the slope concept, it is found that:

The minimum horizontal distance is of 14,281.5 feet.

The maximum horizontal distance is of 15,398.6 feet.

<h3>What is a slope?</h3>

The slope is given by the <u>vertical change divided by the horizontal change</u>.

It's also the tangent of the angle of depression.

In this problem, the vertical change is the altitude of 10,000 feet.

The minimum horizontal distance is with an angle of 35º, hence:

$\tan{35^{\circ}} = \frac{10000}{d}$

$d = \frac{10000}{\tan{35^{\circ}}}$

$d = 14281.5$

The maximum horizontal distance is with an angle of 33º, hence:

$\tan{33^{\circ}} = \frac{10000}{d}$

$d = \frac{10000}{\tan{33^{\circ}}}$

$d = 15398.6$

FRANK has a paper clip.it has a mass of 9g and a volume of 3cm3.what is its density?

Pachacha [2.7K]

Answer:

<h2>3 g/cm³</h2>

Step-by-step explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume} \\$

From the question we have

$density = \frac{9}{3} = 3 \\$

We have the final answer as

<h3>3 g/cm³</h3>

Hope this helps you

I’m the triangle shown below what is the approximate value of x

Dafna1 [17]

Answer:

The answer is choice B: 22.52 units.

Step-by-step explanation:

We use the Pythagoras's theorem which says for a right triangle with sides $x,y$ and hypotenuse $z$ :

$x^2+y^2=z^2.$

In our case

$z=26$

$y=13$

So we solve for $x:$

$x=\sqrt{z^2-y^2}=\sqrt{26^2-13^2} =\boxed{22.52\: units.}$

Which is choice B.
