Answer 1

Answer: The dimensions of the bottom of the drawer are:
20 cm × 40 cm

So the area is : 800 cm² (rectangular shaped)

The area formula of a circle is:
$\pi$ r²
The diameter of the plate is 20cm
so the radius is half the diameter which is 10cm
Apply the given to the formula:
$\pi$ (10)²
100 $\pi$
314.16 cm²

2 plates in the bottom drawer
Area of two plates:
2 × 314.16
628.32 cm²

Area of the non-covered space in the bottom drawer:
Area of drawer - area of two plates
800 - 628.32
171.68 cm²

Bill measures the circumference of a circular fish pond to be 28 ft.What is the diameter of the fish pond, rounded to the nearest foot?
Use 3.14 to approximate pi.

ft

Answers

9ft? to get the circumference, we multiply the diameter to pi, so all we need to do is divide 28 ÷ π, and round.

9ft because to get circumference you multiply by π (pi or 3.14) so to get circumference you just do it the other way around like: 28 ➗π (3.14) = 8.91710... Which rounds to 9. So, the diameter is 9ft. I hope I helped and just message me if you need anything else!

a)46. Take 42 and divide it by 3. Then multiply 14 by 4.
b)2:1. There are 2 wings for every 1 beak on a bird.
c)15 minutes. multiply 50 times 60 and that's how many times it beats per minute. Then divide 45000 by that number and that's how many minutes it should take.
d) 28%. You have to add all the students together, and you get 200. Then you divide 56 by 200.

for the first one:

You take the number of plain chips and divide it by 3, then multiply by four. You do this because there is a 4 to 3 ratio of hot to plain chips.

42 / 3 = 14, 14 x 4 = 56.

Second one:

Birds (usually) have two wings for each beak. Why? I don't know, ask Darwin. There is a 2:1 (two to one) ratio of wings to beaks.

Third:

50 flaps per second, 60 seconds in a minute. 50 x 60 = 3000.

45,000 / 3000 = 15 minutes.

Fourth:

56 + 120 + 24 = 200

56 / 200 = 28% of the students ate pasta

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.

Which value of k makes the equation true?

1) 6

$Answer: \n 12a + 9b = k(2a + (3)/(2) b) \n \Leftrightarrow 6(2a + (3)/(2) b) = k(2a + (3)/(2) b) \n \Leftrightarrow k = 6 \n$

Tanyas boyfriend gave her a box of chocolates for valentines day. 3/4 of the chocolates were milk chocolate. 1/8 of them were white chocolate and the rest were dark chocolate. how many dark chocolate were in the box if there were a total of 16 chocolates in all?

Answers

3/4 of 16 is 12.

16-12=4

1/8 of 16 is 2.

12 of them are milk, 2 of them are white. If you know how many are white, the amount for the other is obvious because it's the same fraction.

2 are dark chocolate
