Step-by-step explanation:

The only correct measurement that represents volume in the list is D.10.1 mm3, which uses cubic millimeters, a standard unit of volume. The others are either measurements of area or contain typos/error in notation.

To select all the measurements that could represent volume, we look for units that indicate three-dimensional space. Volume measurements typically have units raised to the third power, indicating length, width, and height dimensions. The correct options for units of volume are as follows:

Here are clarifications for the other options:

Volume in Various Units

When expressing volume, common standard units include milliliters (mL), cubic centimeters (cm3), and liters (L) for smaller volumes, and cubic meters (m3) for larger volumes. To provide a couple of examples:

Answer:

The length of segment EB = 4

Step-by-step explanation:

* Lets revise a fact in the circle

- When two chords intersect each other inside a circle, the

  products of their segments are equal

* Now lets use this fact to solve the problem

- AB and CD are two chords in the circle intersect each other

 at point E

- The segments of AB are AE and EB

- The segments of CD are CE and ED

* From the fact above

∴ AE × EB = CE × ED

∵ AE = 12 units

∵ EC = 8 units and ED = 6 units

∴ 12 × EB = 8 × 6

∴ 12 EB = 48 ⇒ divide both sides by 12

∴ EB = 4

* The length of segment EB = 4

Answer:

The length of segment EB = 4 units

Step-by-step explanation:

From the figure we can see a circle with two chords intersects each other.

The products of segments of chords are equal

To find the length of EB

we have EC = 8, ED = 6 and AE = 12

From the figure we can write,

AE * EB = EC * ED

EB =  (EC * ED)/AE

 = (8 * 6)/12 = 4 units

Therefore the correct answer is EB = 4 units

5INGH

Step-by-step explanation:

5 × 9 = 45

5 × - v = - 5 v

45 - 5 v

Answer:

This is what you would do!

One, you start off by multiplying 5 into the parentheses (9 and v)

Next, it will look like this,

5(9)-5(v)

Then multiply your equation

5x9=45

5xv=5v

And this is what it would look like

45-5v

(Sometimes this would just stay like this, put if your teacher wants the unknown number to be by itself, this is what you would do next)

Divide 5 to both problems

45/5  5v/5

9=v

Step-by-step explanation:

Answer:

A. 14 times

B. 5 times.

Step-by-step explanation:

We know the volume of the sink, now we need to find the volume of the cup(s) he's using to empty it out.. to find out how many scoops he'll have to do.  

We'll assume he can actually empty it all, even if it's unlikely he can scoop the last 5%-10% of it due to the shapes/sizes of the sink and the cup. We'll also assume he completely fills the cup (which is impossible due to angles).

The volume of the sink is 3000/3 π cubic inches,  let's simplify that as 1000  π cubic inches.

a - Cylindrical cup, diameter 6 inches, height: 8 inches.

We remember the volume of a cylinder is found using this formula:

V = π r²h

So, we have:

V = π * 3² * 8 = 72π

So, how many times does Michael has to scoop (S):

[tex]S = \frac{1000 \pi }{72 \pi } = 13.88[/tex]

Of course, he can't scoop 0.83 times... so we'll round it up.

So, Michael will have to scoop 14 times with this first cup.

b - Cylindrical cup, diameter 10 inches, height: 8 inches.

We remember the volume of a cylinder is found using this formula:

V = π r² h

So, we have:

V = π * 5² * 8 = 200π

So, how many times does Michael has to scoop (S):

[tex]S = \frac{1000 \pi }{200 \pi } = 5[/tex]

So, Michael will have to scoop 5 times with this second cup, which is not surprising since the volume of the second cup is nearly the triple of the first one.

Answer:

The estimate price for all three items is $22.00.

The actual price would be $21.97.

Step-by-step explanation:

To find the estimate price, just round each price to the nearest whole number, so $6.99 → $7.00, $8.99 → $9.00, and $5.99 → $6.00. Add them all together and you'll get $22.00.

To find the actual price without estimating, simply add $6.99 + $8.99 + $5.99, and the answer is $21.97.

Answer is square root of 65

Explanation:

Use the pathagreom theoream: a’2+ b’2= c’2 (C= hypotenus and a + b is legs)

Substitute:

7^2 + 4^2 = c^2

65= c^2

Square root both sides and you get … c= square root of 65

The hypotenuse of the triangle is AB = √65 feet

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of sides of the triangle are

The measure of AC = 7 feet

The measure of side BC = 4 feet

Now , for a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

AB² = AC² + BC²

On simplifying , we get

AB² = 7² + 4²

AB² = 49 + 16

Taking square roots on both sides , we get

AB = √65 feet

Hence , the hypotenuse of the triangle is AB = √65 feet

Answer: First option

12 candy bars were sold

Step-by-step explanation:

Call x the amount of candy sold and call z the amount of cookies sold. Then we know that

[tex]x + z = 20[/tex]

We also know that candy bars sell for $ 3 and cookies sell for $ 5. The profit was $ 76

So:

[tex]3x + 5z = 76[/tex]

To find the quantity of candy bars sold we must solve the system of equations:

[tex]x + z = 20\\\\3x + 5z = 76[/tex]

Multiply the first equation by -5 and add it to the second equation

[tex]-5x -5z = -100[/tex]

               +

[tex]3x + 5z = 76[/tex]

--------------------------------

[tex]-2x = -24\\\\x = 12[/tex]

Brad sold 12 candy bars.

To find this answer, you could do the following steps.

1. Use the formula $3b + $5c = $76 where "b" is the number of bars and "c" is the number of cookies.

2. Fill in each of the given answers (12, 14, 16, 18) into "b".

3. Subtract the given answers from 20 to get the number of cookies (8, 6, 4, 2).

4. Solve to see if it comes out even.

Below are all the solutions in which you use these steps.

A. $3 * 12 + $5 * 8 = $76

$36 + $40 = $76

$76 = $76

True

B. $3 * 14 + $5 * 6 = $76

$42 + $30 = $76

$72 = $76

False

C. $3 * 16 + $5 * 4 = $76

$48 + $20 = $76

$68 = $76

False

D. $3 * 18 + $5 * 2 = $76

$54 + $10 = $76

$64 = $76

False

Thus making 12 the answer. I hope this helps!

Answer:

b.The event may happen, but it is not likely.

Step-by-step explanation:

b.The event may happen, but it is not likely.  Why?  Because the probability given, 0.02, is very close to 0, which would indicate zero chance of the event happening.

Final answer:

The correct answer is b. The event may happen, but it is not likely. This is because a probability of 0.03 suggests a low likelihood of occurrence, being much closer to 0 than to 1.

Explanation:

The probability of an event is a way to quantify the likelihood that the event will occur, represented as a number between 0 and 1. A probability of 0 means an event is guaranteed not to happen, while a probability of 1 means an event is certain to happen. In this scenario, the probability of the given event is 0.03, which is quite small.

Considering that a probability value close to 0 indicates an event that is very unlikely to happen, and value close to 1 indicates an event that is very likely, it can be concluded that:

This statement (b) is true because a probability of 0.03 indicates that there is only a 3% chance of the event occurring, which suggests that while it's not impossible, it's far less likely to happen than not.
