The correct answer is: D urination

ANSWER:

Salt glands allow desert animals to reduce water loss because of Urination.

EXPLANATION:

The salt gland secretes various ions that help the desert animals to excrete excess salt present in the water they consume. This gland produces hyperosmotic fluid that helps in secretion of sodium chloride ions.

So salt-containing water excretes out in the form of urination and the remaining water returns to the blood fluid. Thus water loss through urination is reduced.

Explanation:

Equation of a  straight  line is y= m x + c

m = slope

c is y- intercept

1) y = (-1/2)x + c

substitute (5,-2)  for (x, y) points in the equation above

c = (1/2)

Therefore, the equation of the line is  y = (-1/2)x + (1/2)

substituting the options A  to D in to the equation to check for equality we find that option C does not lie on the Line  it should have been (4, -1.5)

2) y = (3/4)x + c

substitute (3,3)  for (x, y) points in the equation above

c = (3/4)

Therefore, the equation of the line is  y = (3/4)x + (3/4)

substituting the options A  to D in to the equation to check for equality we find that option B does not lie on the Line  it should have been (-6, -3.75)

3) y = (-1/5)x + c

substitute (-7,2)  for (x, y) points in the equation above

c = (3/5)

Therefore, the equation of the line is  y = (-1/5)x + (3/5)

substituting the options A  to D in to the equation to check for equality we find that option D does not lie on the Line  it should have been (4, -0.2)

4) y = (1/2)x + c

substitute (9,3)  for (x, y) points in the equation above

c = (-3/2)

Therefore, the equation of the line is  y = (1/2)x - (3/2)

substituting the options A  to D in to the equation to check for equality we find that option B does not lie on the Line  it should have been (6, 1.5)

5) y = (-2/3)x + c

substitute (5,3)  for (x, y) points in the equation above

c = (1/3)

Therefore, the equation of the line is  y = (-2/3)x + (1/3)

substituting the options A  to D in to the equation to check for equality we find that option A does not lie on the Line  it should have been (-3, 2.333)

6) y = (1/4)x + c

substitute (5,2)  for (x, y) points in the equation above

c = (3/4)

Therefore, the equation of the line is  y = (1/4)x + (3/4)

substituting the options A  to D in to the equation to check for equality we find that option C does not lie on the Line  it should have been (4, 1.75)

7) y = (-3/2)x + c

substitute (3,-4)  for (x, y) points in the equation above

c = (1/2)

Therefore, the equation of the line is  y = (-3/2)x + (1/2)

substituting the options A  to D in to the equation to check for equality we find that option B does not lie on the Line  it should have been (2, -2.5)

8) y = (3/5)x + c

substitute (3,2)  for (x, y) points in the equation above

c = (1/5)

Therefore, the equation of the line is  y = (3/5)x + (1/5)

substituting the options A  to D in to the equation to check for equality we find that option D does not lie on the Line  it should have been (-4, -2.2)

9) y = (1/3)x + c

substitute (5,1)  for (x, y) points in the equation above

c = (-2/3)

Therefore, the equation of the line is  y = (1/3)x - (2/3)

substituting the options A  to D in to the equation to check for equality we find that option A does not lie on the Line  it should have been (6, 1.333)

10) y = (-3/4)x + c

substitute (-5,4)  for (x, y) points in the equation above

c = (1/4)

Therefore, the equation of the line is  y = (-3/4)x + (1/4)

substituting the options A  to D in to the equation to check for equality we find that option B does not lie on the Line  it should have been (-2, 1.75)

Direct Stafford Loans are funded by the federal government, which provides these student loans via the college's financial aid office after changes were enacted in 2010 to eliminate private banks from the lending process.

Direct Stafford Loans are funded by the federal government. These are made to eligible undergraduate and graduate students to assist with the costs of higher education. There are two types of Direct Stafford Loans: Direct Subsidized Loans, which are based on financial need, and Direct Unsubsidized Loans, which do not require proof of financial need.

In March 2010, significant changes were made when President Obama signed a law that effectively transferred the responsibility of issuing student loans from private banks directly to the federal government through the college's financial aid office. This move not only cut out the intermediary private banks, which were assured profits with minimal risk but also aimed to expand the Pell grants program with the savings achieved.

Despite this change, banks still have a role in this system, as they now earn income by servicing the loans instead of originating them.

Answer:

x = 7

Explanation:

Because 25 is a perfect square of 5, we can turn

[tex]5^{3x - 5}[/tex] = [tex]25^{x + 1}[/tex]

into

[tex]5^{3x - 5}[/tex] = [tex]5^{2x + 2}[/tex]

Since the bases are now both equal, we can completely ignore them, as we are only trying to find x. This leaves us with:

3x - 5 = 2x + 2

All we have to do now is solve for x:

x - 5 = 2          Subtract 2x from both sides.

x = 7                Add 5 to both sides.

Hope this helps! :)

Answer:

x = 7

Explanation:

To solve for x in this equation, we're going to need to get the two exponents (3x - 5 and x + 1) equal to each other, but we can't do that unless our bases are the same.

For example, in [tex]A^{x} = B^{x + 1}[/tex], you cannot solve x = x + 1. In [tex]A^{x} = A^{x + 1}[/tex], you can solve x = x + 1.

Just by looking at the bases, 5 and 25, you can tell that it will be simple to make them match. 25 is just 5². The tricky part is going to be figuring out where to put the 2 into x + 1.

Let's look at another example. If you have [tex]2^{2 * 2}[/tex], then you can simplify it to [tex]2^{4}[/tex], which is 16. Or, you could do them one at a time, so [tex](2^{2}) ^{2}[/tex]. This way you'd have 4², which you'd be able to recognize as 16. Based on this example, we know that to make our bases the same, we need to change [tex]25^{x + 1}[/tex] to [tex]5^{2(x + 1)}[/tex].

[tex]5^{3x-5} = 25^{x+1}[/tex]   Change the right side to [tex]5^{2(x + 1)}[/tex]

[tex]5^{3x-5} = 5^{2(x+1)}[/tex]   Simplify that exponent using distribution

[tex]5^{3x-5} = 5^{2x+2}[/tex]  

Now that the bases match, you can get rid of them and just set the exponents equal to each other and solve for x.

3x - 5 = 2x + 2   Add 5 to both sides

3x = 2x + 7   Subtract 2x from both sides

x = 7

Now, check you work!

[tex]5^{3x-5} = 25^{x+1}[/tex]   Plug in 7 for x

[tex]5^{3(7)-5} = 25^{(7)+1}[/tex]   Simplify

[tex]5^{21-5} = 25^{8}[/tex]   Simplify one more time

[tex]5^{16} = 25^{8}[/tex]   Plug these into a calculator if you have one

152587890625 = 152587890625   So you know that x = 7 is correct.

Answer:

280

Explanation:

For ease of comparison $20/hr < $12/hr+ commission, let's do it by the hour first.

Hourly pay of the food truck is $12, every burger she sells, she gets 10% of the $12 burger, which is $1.2. Therefore all we need to figure out is 1.2x +$12 > $20. Minus both sides by 12, now all we have is down to the bare minimum: 1.2*X = $8

8 divided by 1.2 is 6.66 (infinite), but since she can't sell 0.6 of a burger, we need to round up, which is 7, keep in mind we are still at hourly. Now we know that she has to sell at least 7 burgers every hour she's working for the food truck, it's a 40-hour work week, 7*40 is 280.

Check:

Food truck: $12+ 12*0.1*7 = $20.4/hr  $20.4 > $20

Best of luck for your SAT!

Answer:

75

Explanation:

Grace has been eating gummy bears for two days.

 Let n = number of gummy bears at beginning of first day. Then

0.40n = number of gummy bears eaten on first day, and

0.60n = number of gummy bears remaining at end of first day

0.60n = number of gummy bears at beginning of second day.

0.40 × 0.60n = 0.24n = number of gummy bears eaten on second day

0.60n - 0.24n = 0.36n = number of gummy bears remaining at end of second day

0.36n = 27

      n = 27/0.36 = 75

There were 75 gummy bears in the bag at the beginning of the first day.

Answer:

a/b= 2/15

Explanation:

3a +b

----------- = 7/5

b

5(3a+b)=7 x b

15a +5b = 7b

15a = 7b-5b

15a = 2b

15a/2b = 1

a/b x 15/2 =1

we get,

a/b = 2/15

hope you have no doubt now !

If 3a+b/b=7/5. The value of a/b is 2/15.

The area of mathematics known as algebra deals with manipulating or performing operations on abstract symbols rather than numbers.

Algebra is a common thread that runs through practically all mathematics. It involves the study of variables and the rules for manipulating them in formulas.

Since all mathematical applications involve manipulating variables as though they were numbers, elementary algebra is a prerequisite.

Given that, 3a + b/b = 7/5

now cross multiple both side

5(3a+b)=7 x b

15a +5b = 7b

15a = 7b-5b

15a = 2b

15a/2b = 1

a/b x 15/2 =1

Multiply both sides by 2/15

we get,

a/b = 2/15

Therefore, the value of a/b is 2/15.

The probability that someone would be snoring given the percentage of men and women who snore would be 0.5875.

In general, for two independent events A and B, the probability that either A or B occurs is given by:

P(A or B) = P(A) + P(B) - P(A and B)

In this case, we'll need to assume that the man's snoring is independent of the woman's snoring, which seems reasonable in this context.

P(M and W) is the probability that both the man and the woman snore, and since the events are independent, it's given by:

P(M and W) = P(M) * P(W) = 0.45 * 0.25 = 0.1125

Substituting these values into the formula, we get:

P(M or W) = P(M) + P(W) - P(M and W)

P(M or W) = 0.45 + 0.25 - 0.1125

= 0.5875

When the broken clock reaches midnight, the normal clock will read 2:24 AM.

The broken clock loses 12 minutes every hour. Since it started at 12:00 noon and reaches midnight, it has been running for 12 hours (from 12:00 noon to 12:00 midnight). With a loss of 12 minutes per hour, the broken clock will have lost a total of:

Additionally, we know that the broken clock has lost 144 minutes, which is equivalent to 2 hours and 24 minutes (144 minutes ÷ 60 minutes per hour = 2.4 hours). So, when the broken clock reaches 12:00 midnight, the normal clock would be 2 hours and 24 minutes ahead of it.
