In this question, we're trying to find the depth of the fish after 12 seconds

We know that the fish descends at a rate of 18 in. per second.

We need to represent this as an equation

Our equation would be:

y = -18x

x = seconds of descending

y = depth

We don't know where the fish started, so we can assume that it started at a depth of 0

Plug in 12 to the equation and solve:

y = -18(12)

y = -216

The fish would be at a depth of -216 inches.

Answer:

-216 inches

Answer:

216 inches/ 18 feet

Step-by-step explanation:

Multiply the descension by the number of seconds.

18*12 = 216 inches, or 18 feet.

In Drosophila, the genes for withered wings (whd), smooth abdomen (sm) and speck body (sp) are located on chromosome 2 and are s

boyakko [2]

Answer:

The number of expected double crossover progeny is 47.275

To the nearest whole number 47

Step-by-step explanation:

Consider the provided information.

The distance between withered wings (whd) and smooth abdomen (sm) is 30.5,

That means the probability of crossover between them is 0.305.

The distance between smooth abdomen (sm) and speck body (sp) is 15.5,

That means the probability of crossover between them is 0.155

The resulting phenotypically wild-type females were mated with males that had the mutant phenotype for all three traits,

That means the expected frequency of double crossover progeny will be:

0.305×0.155 = 0.047275

It is given that they producing 1000 offspring, therefore,

0.047275×1000 = 47.275

The number of expected double crossover progeny is 47.275

To the nearest whole number 47

A chemist wants to mix a 66% alcohol solution with eight liters of 54% alcohol solution to produce a solution that is 65% alcoho

Rzqust [24]

Answer:

We have 8 liters of 54% alcohol.

We will add "x" liters of 66% alcohol to make "8 +x" liters of 65% alcohol.

54 * 8 + 66 x = 65 (8 + x)

432 + 66x = 520 + 65x

x = 88 liters

Priya drew a circle whose area is 25 cm. Dan drew a circle whose diameter is 4 times the radius of Priya's circle. How many time

Vitek1552 [10]

Answer:

400

Step-by-step explanation:

first work out the radius of priya's circle with the equation a = $\pi r^{2}$

$25 = \pi r^{2}$

$\frac{25}{\pi } = r^{2}$

$r = \sqrt{\frac{25}{\pi } }$

we know the diameter of a circle is 2 times the radius so the diameter of priya's circle is 2x $\sqrt{\frac{25}{\pi } }$

this means that if the diameter of dan's circle is 4 times bigger it must be

8x $\sqrt{\frac{25}{\pi } }$

to find the radius of dan's circle we divide the diameter by to 2 to give

4x $\sqrt{\frac{25}{\pi } }$

then use the a= $\pi r^{2}$ equation again

$a= (4 \sqrt{\frac{25}{\pi } })^{2} \pi$

which equals 400

hope that helped
