A ceramic artist can shape a pot in 3 minutes. It takes 10 minutes to fire one batch of pots in the kiln. If there are p pots in a batch, which expression represents the time it takes to shape and fire one batch of pots? How long will it take the potter to form and fire a batch of 10 pots? A.The expression is 3p. It takes 30 minutes to shape and fire 10 pots.B.The expression is 3p − 10. It takes 20 minutes to shape and fire 10 pots.

C.The expression is 3(p + 10). It takes 60 minutes to shape and fire 10 pots.

D.The expression is 3p + 10. It takes 40 minutes to shape and fire 10 pots.

Answers

Answer 1

Answer:

Answer:

D. The expression is $3p+10$ . It takes 40 minutes to shape and fire 10 pots.

Step-by-step explanation:

Let the number of pots in a batch = p

Now, one pot takes 3 minutes to get in a shape.

Then, 'p' pots will take $3p$ minutes to get in a shape.

Also, it takes 10 minutes to fire one batch of pots.

Thus, the expression for the time taken to form one batch of pots = $3p+10$

So, when number of pots = 10 i.e. p= 10.

Time taken to fire the pots = $3* 10+10$ = 30+10 = 40

That is, 'It takes 40 minutes to shape and fire 10 pots'.

Thus, option D is correct.

Answer 2

Answer: 3p to shape and 10 minutes to fire
= 3p + 10
3x10 + 10 = 40 minutes for a batch of 10 pots
therefore D is the correct answer

A kayaker paddles 2 km upstream in the same time that it takes to paddle 3 km downstream. The average speed of the current is 1 km/h. What is the average speed of the kayak in still water?I need the work as well pleasee!!

Answers

Let x represent speed of kayak in the still water.

We have been given that a kayaker paddles 2 km upstream in the same time that it takes to paddle 3 km downstream. The average speed of the current is 1 km/h.

Speed of kayak upstream would be speed of kayak in still water minus speed of the current that is $x-1$ .

Speed of kayak downstream would be speed of kayak in still water plus speed of the current that is $x+1$ .

$\text{Time}=\frac{\text{Distance}}{\text{Speed}}$

Time taken to travel 2 km upstream would be $(2)/(x-1)$ .

Time taken to travel 3 km upstream would be $(3)/(x+1)$ .

Since both times are equal, so we can equate both expressions as:

$(3)/(x+1)=(2)/(x-1)$

Cross multiply:

$3(x-1)=2(x+1)$

$3x-3=2x+2$

$3x-2x-3=2x-2x+2$

$x-3=2$

$x-3+3=2+3$

$x=5$

Therefore, the average speed of Kayak in still water is 5 km per hour.

A bag contains 24 blue marbles, 32 yellow marbles, 43 white marbles, and 21 red marbles. If a marble is drawn from the bag and replaced 90 times, about how many times would a yellow marble be drawn? A. 15 B.24 C.30 D.60

Answers

The answer would be B
Steps
1. Add all the numbers 43+24+32+21

2. You should get 120

3. 120 will be your denominator

4. Determine how many yellow marbles there are, there are 32

5. Simplify 32/120 you should get 4/15, I simplified by 2 to get the answer, I simplified until I could simplify no more

6. Now change 4/15 to a decimal

7. To do step 6 you must divide 4 by 15

8. you should get0.26666666666

9. Now multiply 90*0.26666666666

10. You should get 23.9

11. round 23.9 by tenth place

12. You should get 24 thats how the answer is B
