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?The expression is 3p. It takes 30 minutes to shape and fire 10 pots.

The expression is 3p − 10. It takes 20 minutes to shape and fire 10 pots.

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

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

Answers

3p + 10 (40 minutes)

3p+10. 3 minutes per pot to shape it. Time taken to shape all p pots is 3p. Then it takes 10 minutes to fire the batch.

The function y=-4(x - 3)2 + 8 shows the daily profit (in hundreds of dollars)of a taco food truck, where x is the price of a taco (in dollars). Find and
interpret the zeros of this function,
Select two answers: one for the zeros and one for the interpretation.
O
A. Interpretation: The zeros are where the daily profit is $0.00.
O B. Zeros: x = 3 - V3 = 1.58 and x = 3 + v = 4.41
O
c. Interpretation: The zeros are where the price of a taco is $0.00.
O D. Zeros: x = 3 and x = -3

Answers

Answer:

Interpretation: The zeros are where the daily profit is $0.00.

Zeroes are x = 1.58 and x = 4.41.

Step-by-step explanation:

Given function,

$y=-4(x-3)^2+8$

For finding the zeros,

y = 0,

$-4(x-3)^2+8=0$

$-4(x-3)^2=-8$

$(x-3)^2=2$

$x-3=\pm √(2)$

$\implies x = 3\pm √(2)$

$\implies x\approx 4.41\text{ or }x=1.58$

Hence, the zeroes of the function are x = 1.58 and x = 4.41,

∵ x represents the price of a taco and y represents daily profit,

Therefore, the zeroes are where the daily profit is $ 0.00.

Answer:

Step-by-step explanation:

To find the zeros, set y=-4(x - 3)2 + 8 = 0. Then -4(x - 3)^2 = -8, and:

4(x - 3)^2 = 8. Dividing both sides by 4 yields (x - 3)^2 = 2.

Taking the square root of both sides yields x - 3 = ±2, so that

x = 3 ±2, or x = 5 and x = 1. These are the zeros. The correct interpretatioon is A: where the daily profit is $0.

Boys:girls in a ratio 2:4. If there are 12 boys, how many girls

Answers

It would be 24 girls because 12 is half of 24, just like 2 is half of 4. It's also 24 because it's multiplying by 6, and 6 x 4 = 24.

Solve for c in a+b+c=180

Answers

Answer:

c = -a - b + 180

Step-by-step explanation:

Isolate the c. Note the equal sign, what you do to one side, you do to the other. Subtract a and b from both sides

a (-a) + b (-b) + c = 180 (-a) (-b)

c = 180 - a - b

c = -a - b + 180 is your answer

What is the area of a rectangle with the height of 25mm, and the length of 12mm? After you get the product, turn it into feet.

Answers

Area = (length) x (width) = (25mm x 12mm) = 300 square millimeters

You can't convert 'square millimeters' to feet. One is a unit of area,
but the other is a unit of length.

You can convert square millimeters to square feet, though.

(300 mm²) x (1 ft / 304.8 mm)² = 0.00323 square foot (rounded)

300 feet is the answer
