Original:28
New:25

Original:21.2
New:10.75

Original:37
New:39

Original: $4.29
New:$2.82

Answers

Answer 1

Answer:

#1 = 10.71% decrease (not sure if you should write -10.71%)

#2 = 49.29% decrease (-49.29%) (-49.30% rounded)

#3 = 5.4% increase

#4 = 34.26% decrease (-34.26%. -34.27 if your teacher wants it rounded.)

Step-by-step explanation:

Original:28

New:25

Increase ÷ Original Number × 100.

28-25 =3

3/28 = 0.1071

0,1071*100= 10.71

Original:21.2

New:10.75

21.2-10.75= 10.45

10.45/21.2 = 0.4929

0.4929*100 = 49.29 (49.30)

Original:37

New:39

difference = 2

2/37 = 0.054

0.054*100 = 5.4

Original: $4.29

New:$2.82

4.29-2.82 = 1.47

1.47/4.29 = 0.3426

0.3426*100 = 34.26 (34.27)

Hope this helps! Have a great day! Also, let me know if it is correct.

Step-by-step explanation:

The population of 150,000 decreases each year by 150

  Since the population is decreasing it would be -150 iguana's

       

         \(\frac{-150 iguanas }{1 year}\)

Answer: A

Step-by-step explanation:

facts

there are 150,000 iguanas. each year, we lose 150.

The rate of change is a fixed amount of something increasing or decreasing in a certain amount of time. Since the population loses 150 iguanas each year, the rate of change, or unit rate, is -150 (if it decreases, its negative).

When rolling a 6-sided die twice, determine P(sum of 4).

A. 3/36
B. 5/36
C. 6/36
D. 2/6

Answers

the probability of rolling a sum of 4 when rolling a 6-sided die twice is,

⇒ 3 / 36.

What is mean by Probability?

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Now, To determine the probability of rolling a sum of 4 when rolling a 6-sided die twice, we need to first find all the possible outcomes when rolling a die twice.

Since, There are 6 possible outcomes when rolling a single die:

1, 2, 3, 4, 5, or 6.

Now, When rolling two dice, we can combine each of these outcomes with every other outcome.

Hence, This gives us a total of 6 x 6 = 36 possible outcomes when rolling two dice.

Thus, To find the number of outcomes that add up to 4, we can list them out:

1 + 3

2 + 2

3 + 1

So, there are three possible outcomes that add up to 4.

Hence, To find the probability of rolling a sum of 4, we need to divide the number of outcomes that add up to 4 by the total number of possible outcomes:

⇒ P(sum of 4) = 3/36

Therefore, the probability of rolling a sum of 4 when rolling a 6-sided die twice is 3 / 36.

The circumference of a woman’s basketball must be between 28.5 in. and 29 in., inclusive. What is a compound inequality that could show this?

Answers

Answer:

The ball should be BOTH greater than 28.5 AND less than 29 (although I don't think it's in inches...) Since it is not explicitly stated, let's assume we're talking about the basketballs diameter, D.

 

So now this may be written D > 28.5 and D < 29. Combining these two, we can write 28.5 < D < 29.

   

Also not explicitly stated is whether or not the basketball may be equal to 28.5 or 29. If, indeed, that is the case, then instead we may write this as D >= 28.5 and D <= 29, or combining, 28.5 <= D <= 29.

Hope this helps :D.

The compound inequality is 28.5 <= D <= 29.

It is required to find the compound inequality.

What is compound inequality?

A compound inequality  is two or more inequalities joined together with or or and . To be a solution of an or inequality, a value has to make only one part of the inequality true. To be a solution of an and inequality, it must make both parts true. For example: x≤−3 or x>2.

Given:

The ball should be BOTH greater than 28.5 AND less than 29 (although I don't think it's in inches...) Since it is not explicitly stated, let's assume we're talking about the basketballs diameter, D.

According to given question we have,

So now this may be written D > 28.5 and D < 29. Combining these two, we can write 28.5 < D < 29.

Also not explicitly stated is whether or not the basketball may be equal to 28.5 or 29. If, indeed, that is the case, then instead we may write this as D >= 28.5 and D <= 29, or combining, 28.5 <= D <= 29.

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.

Which one is right and why?

Answers

THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

Answer: A. -47

Hey ! there

Answer:

Value of expression is -47 . That means Option A is correct answer .

Step-by-step explanation:

In this question we are provided with an expression that 5 ( v - 10 ) - 7 and value of v as 2 . And we are asked to find the value of expression when value of v is 2 .

Solution : -

\( \quad \: \longmapsto \qquad \: 5(v - 10) - 7\)

Step 1 : Substituting value of v as 2 :

\( \quad \: \longmapsto \qquad \:5(2 - 10) - 7\)

Step 2 : Solving parenthesis :

\( \quad \: \longmapsto \qquad \:5( - 8) - 7\)

Step 3 : Multiplying 5 with -8 :

\( \quad \: \longmapsto \qquad \: - 40 - 7\)

Here we get ,

\( \quad \: \longmapsto \qquad \: \pink{\underline{\boxed{\frak{- 47}}}}\)

Henceforth , value of expression when v = 2 is -47 .Therefore , Option A is the valid answer.

Use the formula below if the sphere has a volume of 64π

V=4/3πr^3

Answers

The first step would be to plug in the given volume and solve for the radius, r:

64π = 4/3πr^3

Divide both sides by (4/3)π:

64π / (4/3)π = r^3

Simplify:

48 = r^3

Take the cube root of both sides:

∛48 = r

Simplify:

r ≈ 3.63

Therefore, the radius of the sphere with a volume of 64π is approximately 3.63 units.

Answer:

the value of r will be r =3.63

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

Answers

The value of A/B is given as follows:

What are the asymptotes of a function f(x)?

The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.

From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:

B = -1 -> as x + B = 0 -> x = -B = -1.

When x = 0, y = -2, hence the value of A is obtained as follows:

A/-1 = -2

A = 2.

Then the division is given as follows:

A/B = 2/-1 = -2.
