D. A kidney is an organ is correct.

Step-by-step explanation:

A kidney is a part of our body that cleans our blood, ridding it of all uncleanliness, similar to a water filter.

A kidney is an organ because it's one of the essential parts of our body that we need to survive. Our body couldn't live with too much/ too little salt and other substances in our blood.

Therefore, the correct answer is D. A kidney is an organ.

given x = 2^p and y = 2^q, express in terms of x and/or y

I) 2^p+q

II) 2^2p

III) 2^q-1

Answers

Answer:

|||)2^ (p + q) = 2^p • 2^q because you'd add the exponents, so xy2^ 2q = 2^(q + q) = 2^q • 2^q as above, so y^22^ (p-1) = 2^p / 2^1 because you subtract exponents when dividing, so x/2

If xy = 32 then x = 32/yso 2xy^2 would = 2(32/y)•y^2 = 64y = 32 so y = 1/2making x = 64 since xy = 32

so 64 = 2^p; p = 61/2 = 2^q; q = -1

2 3/4 - 5 1/8
simplified : 11/4 - 41/8
create a common denominator : 11/4x8 is 88/32 and 41/8x4 is 328/32
simplified : 88/32 - 328/32
simplified : 11/4 - 41/4 (divide both of the fractions by 8)
11/4 - 41/4 is -30/4
the answer is -30/4 or -7 2/4 or -7 1/2
Answer is -2 3/8

Step by step

To add or subtract fractions, the denominator (bottom) has to be the same, so you are working with the same fractional part of the whole.

The product of the given fractions is 21.

The given expression is 9 × [tex]2 \frac{1}{3}[/tex]

What is the fraction?

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Now, the product of fraction can be solved by multiplying numerators and write the result in numerator and multiplying denominators and write the result in denominators.

That is, 9 × [tex]2 \frac{1}{3}[/tex] = 9 × [tex]\frac{7}{3}[/tex] = 21

Therefore, the product of the given fractions is 21.

What is the value of x in the equation? 6(x +1) -5x = 8 + 2(x - 1) *

Answers

Answer:

x = 0

Step-by-step explanation:

6 ( x + 1 ) - 5x = 8 + 2 ( x - 1 )

6x + 6 - 5x = 8 + 2x - 2

-x = 0

x = 0

Answer:

x = 0

Step-by-step explanation:

First distribute both sides to simplify the equation

6(x +1) -5x = 8 + 2(x - 1)    =

6x + 6 - 5x = 8 + 2x - 2

Combine like terms

x + 6 = 6 + 2x

Subtract x from both sides

6 = 6 + x

Subtract 6 from both sides

0 = x

Compare -8.9 and -9.3.


A.
-8.9 = -9.3

B.
-8.9 > -9.3

C.
-8.9 < -9.3

Answers

A number line will be helpful to compare the two of the given terms. The correct option is B, -8.9 > -9.3.

What is a number line?

A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. It’s not a ruler, so the space between each number doesn’t matter, but the numbers included on the line determine how it’s meant to be used.

The two of the given numbers can be compared as shown below.

-8.9 > -9.3

This is because on a number line, numbers on left are of less value than numbers on the right. And since -8.9 is close to 0, then -9.3.

Hence, the correct option is B, -8.9 > -9.3.

If a driver uses 1/ 10 of gas every day what fraction of a tank will he use in 1 week​

Answers

The fraction of gas the driver use in one week is 7/10 of a tank.

Fraction of gas the driver use in one week

A fraction is a number which has a numerator and a denominator. such as 7/10

Numerator refers to the upper or top value. 7 is the numerator.

Denominator refers to lower or bottom value. 10 is the denominator.

Fraction of gas used in a day = 1/10Number of days in a week = 7 days

Fraction of gas the driver use in one week = Fraction of gas used in a day × Number of days in a week

= 1/10 × 7

= (1 × 7) / 10

= 7/10 of a tank

Therefore, the fraction of gas the driver use in one week is 7/10 of a tank.

For the experiment of rolling an ordinary pair of​ dice, find the probability that the sum will be less than 3 or greater than 5.

Answers

According to the given statement the probability that the sum will be less than 3 or greater than 5 = 27/36.

What is Probability?

Probability is simply the likelihood of something occurring. When we are uncertain about the result of an event, we might discuss the probabilities of several outcomes—how likely they are. Statistics is the study of occurrences guided by probability.

According to the given information:

When two dice are rolled, the total number of possible outcomes is 36.

sum     possibilities            probability(favorable/ total outcomes of the event)

2          (1,1)                                                       1/36

3          (1,2) , (2,1)                                             2/36

4          (2,2), (3,1) , (1,3)                                    3/36

5          (4,1), (1,4),(2,3),(3,2)                              4/36

6          (1,5),(5,1),(2,4),(4,2),(3,3)                       5/36

7           (2,5),(5,2)(1,6),(6,1),(3,4),(4,3)               6/36

8           (2,6),(6,2), (5,3),(3,5),(4,4)                   5/36

9           (3,6),(6,3),(5,4),(4,5)                            4/36

10          (5,5),(4,6),(6,4)                                   3/36

11           (6,5),(5,6)                                            2/36

12          (6,6)                                                    1/36

probability that the sum will be less than 3 or greater than 5 = probability for the sum to be 2 +  probability for the sum to be 6 +  probability for the sum to be 7 + probability for the sum to be 8 + probability for the sum to be  9 + probability for the sum to be 10 + probability for the sum to be 11 + probability for the sum to be 12.

=   (1/36) + (5/36) + (6/36) + (5/36) + (4/36) + (3/36) + (2/36) + (1/36)

= (1 + 5 + 6 + 5 + 4 + 3 + 2 + 1)/36

= 27/36

According to the given statement  the probability that the sum will be less than 3 or greater than 5 = 27/36.
