a fish tank has a base of 45cm2 and is filled with water to the depth of 12cm. if the height of the tank is 25cm, how much more water will be needed to fill the tank to the brim?

Answers

Answer 1

Answer: volume = base area x height.
Required amount of water = volume of tank - amount of water currently in the tank. = (45 x 25) - (45 x 12) = 45(25 - 12) = 45 x 13 = 598 cm^3

What times what equals 19

Answers

19 is prime meaning that only 1 and itself can multiply to get that number (excluding decimals and fractions)
so the answer would be 1 times 19

or if you want to multiply by a fraction to divide you could do
38 times 1/2=19

The number 19 is a prime number, which means it is only divisible by 1 and itself.

In the case of 19, it is a prime number because it has only two distinct factors: 1 and 19. This means that there are no other whole numbers that you can multiply together to obtain 19.

To illustrate this further, let's check all the possible pairs of numbers that could potentially multiply to 19:

1 * 19 = 19

As you can see, the only combination of two numbers that yields 19 as their product is 1 and 19.

Therefore, 19 cannot be expressed as the product of two different whole numbers.

Answer:

Area of the rectangle: 24 cm²
Area of the circle: 380.13 cm²
Area of between the circle and the rectangle: 356.13 cm²

Explanation:

The question describes a rectangle of dimensions 4 cm × 6 cm inscribed in a circle with radius 11 cm.

You can find:

The area of the rectangle
The area of the circle
The area between the rectangle and the circle.

1. Area of the rectangle:

$Area=length* width=4cm* 6cm=24cm^2$

2. Area of the circle:

$Area=\pi* radius^2=\pi * (11cm)^2\approx 380.13cm^2$

3. Area between the rectangle of the circle:

This is the area of the circle that does not belong to (or is outside of) the area of the rectangle.

$Area=\text{area of the circle - area of the rectangle}\n \n Area=380.13cm^2-24cm^2=356.13cm^2$

The average weight of the largest fish, the whale shark, is 50,000 pounds. How many tons is this?

Answers

1 ton = 2000 lbs
so we just need to divide 50,000 by 2000 and we have our answer
$(50000)/(2000) =$ 25 tons

3/4 (4c + 16) = 2c ÷ 9. what is c

Answers

Distribute

(3/4)(4c)+(3/4)(16)=2c/9

3c+12=2/9 c

Now subtract 2/9 c from both sides

3c+12-2/9 c=2/9 c-2/9 c

25/9 c+12 =0

Now we need to subtract 12 from both sides

25/9 c+12-12=0-12

25/9 c=-12

Just multiply both sides by 9/25 so we find the value for c

25/9 *(25/9 c)=-12(9/25)

c= -108/25

Let x represent the cost of an adult ticket, and let y represent the cost of a child’s ticket. Which graph represents the possible costs of the tickets?

Answers

(2y + 4x) - 4x = (40) - 4x
2y = -4x + 40
(2y) / 2 = (-4x + 40) / 2
y = -2x + 20
20 is the y intercept
(-2 / 1) is the slope

B

(Or whichever the one that has a y-intercept of 20 and an x-intercept of 10.)

the answer is B or the 2nd option
