A small bar of gold measures 20 mm by 250 mm by 2 mm. One cubic millimeter of gold weighs about 0.0005 ounces. Find the volume in cubic millimeters and the weight in ounces of this small bar of gold.

Answer: 36

Step-by-step explanation: 6 + 3 = 9.

4 * 9 = 36

Veronica's statement is reasonable because they cost more than $30.

The total amount of sandwiches is $36

Given that:

She buys 1 sandwich for $4

She buys 6 ham sandwiches and 3 cheese sandwiches

To find the total cost for Veronica would be:

6+3 = 9 total sandwiches

4 * 9= 36 total cost of the sandwiches.

Therefore, Veronica's statement is reasonable because they cost more than $30

Using the volume formula, we will see that the volume of the sphere is V = 381.51 cm^3

For a sphere of radius R, the volume is given by the formula:

[tex]V = (\frac{4}{3})*3.14*R^3[/tex]

In this case, we can see that the diameter is 9 cm, then the radius is half of that:

R = 9cm/2 = 4.5cm

Now that we know the radius, we can replace it on the volume formula to get:

[tex]V = (\frac{4}{3})*3.14*(4.5cm)^3 = 381.51 cm^3[/tex]

Answer:

   they wont need to hire someone for nine months.

Charlie will be gone in 6 months, while Dash has 3 more months after til she leaves.

Answer: 18 months

Step-by-step explanation:

If both of them aren't at home, then they hire someone to look after the dog. However, if Charlie is on a trip and Dasha isn't, they don't. So they would need to be at business trips at the same time and that means they will hire someone to look after the dog. So we find the LCM of 6 and 9 which is 18 months.

Answer:

x > 5  should be your solution to the inequality.

Step-by-step explanation:

Your inequality: 14 - 3x < -1

You need to do two-step inequalities which are similar to two-step equations but different since you're using an inequality symbol as opposed to an equal sign.

Steps:

14 - 3x < -1

Subtract 14 from both sides

-3x < -1-14

Solve -1-14

That should be -15

-3x < -15

**You have to switch the inequality due to multiplying negatives rule.

While dealing with inequalities, when multiplying negatives the inequality sign should switch to its opposite.

-3x > -15

x > 5

5 is lesser than x

Answer:

∠1, ∠3, ∠5 and ∠7 = 126°

∠2, ∠4, ∠6 and ∠8 = 54°

Step-by-step explanation:

∠3 + ∠4 = 180°

If ∠3 = 126°, ∠4 = 54°

The same applies for ∠1 and ∠2, ∠5 and ∠6, ∠7 and ∠8 respectively.

Therefore,

∠1  = 126°,

∠3 = 126°,

∠5 = 126°, and

∠7 = 126°

∠2 = 54°,

∠4 = 54°,

∠6 = 54°, and

∠8 = 54°

3. Solve for b

-1 = b

All together the final equation is y=4x-1

Answer:

i think the first one

Step-by-step explanation:

so to do this, you first have to look at what the x means and what the y means

the x means the time

the y means the speed

now we check the graph, from the points (1, 112) and (7, 16) does x decrease? yes it does

so we can cross out all the "increase x "choices, you could choose the answer now, but lets undertstand

when x decreases y also decreases. you can know because when x is 1 y is 112 but when x is 2, y is 96

We need a system of equations to find the number of each type of ticket sold.

Thus, we have [tex]x+y=60[/tex], where x = the number of $6 tickets and y = the number of $10 tickets

We also have [tex]6x+10y=540[/tex]

We can use the elimination method to find y:

Answer:

0.95

Step-by-step explanation:

The probability that the next customer will pay with cash or a credit card is approximately 0.95 or 95%.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

To find the probability that the next customer will pay with cash or a credit card, we need to add the number of customers who paid with cash and the number of customers who paid with a credit card, then divide this sum by the total number of customers:

Number of customers who paid with cash or credit card.

= 53 + 2

= 55

Total number of customers

= 53 + 3 + 2

= 58

,

The probability that the next customer will pay with cash or a credit card is:

= 55/58

= 0.95 (rounded to the nearest hundredth)

Thus,

The probability that the next customer will pay with cash or a credit card is approximately 0.95 or 95%.
