A snake at the zoo is 4 feet long. A scale model of the snake is 2 inches long. What is the scale factor?

Answer:

-20/12 as an example there are many others

mmm  answer is 139.5 (C)

7x4.5=31.5

12x9=108

108+31.5=139.5

Answer:

A=139.5cm^2

Step-by-step explanation:

12x9=108---->Area of the rectangle A=l x w

9x7=63 divided by 2=31.5--->Area of the triangle  A=1/2 (b x h)

108+31.5=139.5cm^2

Hope this helps and can you give me brainliest pls?

1. 12/40 or 30% chance

2. 60

Explanation: 1. Not gonna lie i searched it up

2. x/200 times 12/40 = 2400/40

Answer:

11.5

Step-by-step explanation:

x=8 & y=23

then

x=4 is half so you divide by 2

so half of 23 would be 11.5. If you are rounding then it would be 12

Answer:

Answer is E but not 100%

Step-by-step explanation:

Answer:

A is correct

E shows an error as the first two values are identical so one cannot be greater than the other.

Step-by-step explanation:

A shows 2.69 is equal to 2.696 which is more than 2.696 which is more than 2.696 which is more than 2.696

As when;

2.696 repeats in bold = 2.696969696  1st greatest

2.696 repeats in bold = 2.696696696 2nd in highest value so 2nd in order.

2.696 repeats in bold = 2.696666666 3rd in highest value so 3rd in order.

2.696 does not repeat = 2.696 so is the least greatest from the list.

Answer:

$15 / hr

$450 / week

Step-by-step explanation:

30 h x 52 w = 1560 hrs

$23400 / 1560 = $15 / hr

$15 * 30 hrs = $450 / week

Step-by-step explanation:

4<a<5

2<b<4   multiply

4x2 < axb < 5x4

8<ab < 20

Answer:

1<a/b<2.5

Step-by-step explanation:

bro you're gonna give me brainless ://

We are given 4<a<5 and 2<b<4 and are asked to find a/b.

Since there is a wide range of values of numbers from 4 to 5 and 2 to 4, there is no definite answer to this. However, we can take the most extreme values here and write them on the opposite ends of the inequality.

For example, the lowest value here is >4/4 (>1) because that is the smallest value from the first inequality divided by the largest value from the second inequality. The other extreme is the biggest value possible, which is <5/2 (<2.5).

Given these extremes, we can now rewrite the inequality.

(smallest value)<a/b<(largest value)

1<a/b<2.5

Answer:

C) C, B, D, E, A, F

Step-by-step explanation:

The closer the data points are to each other along the line of best fit on a scatter plot, the greater the correlation coefficient and vice versa.

Therefore, the scatter plot that has the least correlation coefficient would be the scatter plot with the data points that are farther apart from each other along the line of best fit which is C, followed by B, D, E, A, and F.

Answer:

Six Hundred Thousand One Hundred and Eight

Answer: C

Step-by-step explanation:

→ When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed).

→ If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.

Answer:

(a,b) ⇒ (-a,-b)

Step-by-step explanation:

When you reflect over the x-axis, the y-value changes sign.

When you reflect over the y-axis, the x-value changes sign.

So if you reflect across both, both values change sign. That is, if you reflect the point (a,b) across both axes, you will get (-a,-b)

(I've also attached a table that's handy for other reflections if you're curious)

Answer:

The best point estimate of the proportion of adults in the population who say that the law goes easy on celebrities is 0.72.

Step-by-step explanation:

Confidence interval concepts:

A confidence interval has two bounds, a lower bound and an upper bound.

A confidence interval is symmetric, which means that the point estimate used(best point estimate) is the mid point between these two bounds, that is, the mean of the two bounds.

In this question:

The two bounds are 0.692 and 0.748.

a.What is the best point estimate of the proportion of adults in the population who say that the law goes easy on celebrities.

The mean of the bounds, so:

(0.692+0.748)/2 = 0.72

The best point estimate of the proportion of adults in the population who say that the law goes easy on celebrities is 0.72.

Answer: $1.45

Step-by-step explanation:

We start by subtracting the change from how much she payed for.

d = dollars | g = goldfish

[tex]16d - 0.05d = 15.95d[/tex]

Then we divide by the goldfish

[tex]\frac{15.95d}{11g} = 1.45d[/tex]

Our answer is 1.45!

Answer:

g = 41⁄4

Step-by-step explanation:

4g + 13 = 54

∴ g = 41⁄4

Answer:

[tex]a = - 5[/tex]

Step-by-step explanation:

[tex]6 - 3a = 21 \\ - 3a = 21 - 6 \\ - 3a = 15 \\ \frac{ - 3a}{ - 3} = \frac{15}{ - 3} \\ a = - 5[/tex]

Hope this helps you.

Can I have the brainliest please?

Answer:

a = -5

Step-by-step explanation:

When you're solving a question like this, your aim is to get the unknown (in this case 'a') by itself on one side of the equation. You do this by adding/subtracting/multiplying/dividing, whatever is necessary for the question. Note that if you do something to one side of the equation, you must do the same to the other.

6-3a=21

First let's get rid of the 6: subtract 6 from both sides.

6-6-3a=21-6

-3a=15

Now let's get rid of the -3: divide both sides by -3.

-3a=15

-3a/-3 = 15/-3

a= -5

Solution :

Let

Waiting time for accessing one record = W

Read time for moving the information = R

Total time for accessing to get one block of information = X

So, the random variable X is defined as :

X = W + R

  = W + 7

a). Calculating E(X)

E(X) = E(W+7)

      = E(W) + 7

      [tex]$=\int_{0}^{28}\frac{1}{28-0}w dw +7$[/tex]

       [tex]$=\frac{1}{28}\int_{0}^{28}w dw +7$[/tex]

       [tex]$=\frac{1}{28}\left[\frac{w^2}{2}\right]_0^{28}+7$[/tex]

      [tex]$=\frac{1}{56}\left[28^2\right]+7$[/tex]

      [tex]$=\frac{28}{2}+7$[/tex]

     = 14 + 7

     = 21

b). Calculating Var(X)

V(X) = V(W+7)

      = V(W)+0

      = V(W)

     = [tex]$E(W^2)-[E(W)]^2$[/tex]

     [tex]$=\int_0^{28}\frac{1}{28}w^2 dw-[14]^2$[/tex]

    [tex]$=\frac{1}{28}\left[\frac{w^3}{3}\right]_0^{28}-196$[/tex]

   [tex]$=\frac{1}{28\times 3}\times 28^3-196$[/tex]

  [tex]$=\frac{28\times 28}{3}-196$[/tex]

 = 65.33

c). Considering A is the random variable that can be defined as follows:

A = 6(W+7)

   =6W + 42

So calculating E(A)

E(A) = E(6W + 42)

      = E(6W) +42

      = 6E(W) + 42

     = 6(14) + 42

     = 84 + 42

     = 126

Answer:

m∠G = 31.83°

Step-by-step explanation:

From the triangle FGH,

FH = 6 ft

FG = 11 ft

And measure of the included angle ∠F = 73°

We have to find the measure of ∠G.

By applying law of cosine in the triangle to get the measure of third side GH first,

GH² = FH² + FG² - 2(FH)(FG)cos(∠F)

GH² = 6² + 11² - 2(6)(11)cos(73°)

GH² = 36 + 121 - 38.593

GH = √118.407

GH = 10.88 ft

Now apply sine rule in the given triangle to get the measure of ∠G.

[tex]\frac{\text{sinG}}{FH}=\frac{\text{sinF}}{GH}[/tex]

[tex]\frac{\text{sinG}}{6}= \frac{\text{sin(73)}}{10.88}[/tex]

sin(G) = 0.527374

G = [tex]\text{sin}^{-1}(0.527374)[/tex]

m∠G = 31.83°

Answer:

No, because he has a sum of 0.

Step-by-step explanation:

Answer:

She can water 20 plants

Step-by-step explanation:

She has a total of 2 liters in each can, and if she uses 2 full cans, she has a total of 4 liters. 4 liters=4000 milliliters.

To find the amount of plants she can water, we need to divide the amount of water she has by how much it takes to water each plant. So,

[tex]\frac{4000}{200}[/tex]

[tex]=\frac{20}{1}[/tex]

[tex]=20[/tex]

So, she can water 20 plants with two full water cans.
