Answer:

The answer is: 5/20 or a 25% chance

The probability that the pet store owner randomly selects a grey mouse for the window display is 0.25 or 25%.

The question asks for the probability of selecting a grey mouse from a pet store that has a total of 20 mice consisting of 11 white, 5 grey, and 4 brown mice. To find the probability, we use the ratio of the number of grey mice to the total number of mice.

The formula for probability is:

Probability (P) = Number of favorable outcomes / Total number of outcomes

We apply the formula as follows:

P(grey mouse) = Number of grey mice / Total number of mice = 5 / 20 = 0.25 or 25%

Therefore, the probability that the pet store owner selects a grey mouse for the window display is 25%.

Answer: y=- 1/3x

Step-by-step explanation:

Answer:

The correct option is C.) half the measure 62°

Step-by-step explanation:

i) Intercepted arc measures 124°

ii) The measure of the inscribed angle will be half of the intercepted arc

  therefore inscribed angle  = 124° / 2 = 62°

iii) Therefore the correct option is C.) half the measure 62°

The measure of an angle inscribed in a circle is half the measure of its intercepted arc. Therefore, if the intercepted arc is 124°, the inscribed angle would be 62°.

This problem is related to the relationship between arcs and inscribed angles in circles. In geometry, there's a specific rule that states: the measure of an angle inscribed in a circle is half the measure of its intercepted arc.

Therefore, if the intercepted arc measures 124°, its inscribed angle would have half the measure, or 62°. If the inscribed angle were to have the same measure, it would imply that the arc measure was double the angle, which is not the case here.

Answer:

2)  m∠CBD = 60         3) x=15; 95 and 85     4) 12 = x; 98 for both angles

Step-by-step explanation:

2)  2x + 14 + x + 7 = 90       The angles add up to 90 degrees

    3x + 21 = 90                   Combine like terms

          - 21  - 21                    Subtract 21 from both sides

    3x = 69                           Divide both sides by 3

     x = 23

Plug 23 in the equation

2(23) + 14

46 + 14

60

3)  2x + 65 + 3x + 40 = 180       The angles add up to 180 degrees

    5x + 105 = 180                      Combine like terms

          - 105  - 105                      Subtract 105 from both sides

5x = 75                                       Divide both sides by 5

x = 15

Plug in 15 into both equations

2(15) + 65 = 95

3(15) + 40 = 85

4) 5x + 38 = 9x - 10

  - 5x         - 5x                 Subtract 5x from both sides

38 = 4x - 10

+ 10       + 10                      Add 10 to both sides

48 = 4x                              Divide both sides by 4

12 = x

Plug in 12 into both equations

5(12) + 38 = 98

9(12) - 10 = 98

64 inches

Step-by-step explanation:

12 inches equals 1 foot so

12*5=60 inches which means it will be bigger than 5 feet.

Answer:

70 gallons

Step-by-step explanation:

x gallon of 50%

x * 0.5 + 70 * 0.3 = (x + 70) * 0.4

0.5x + 21 = 0.4x + 28

0.1x = 7

x = 70

To get a mixture that is 40% antifreeze, we need to mix 70 gallons of 30% antifreeze solution with 40 gallons of 50% antifreeze solution. This conclusion is reached by establishing an equation representing the total amount of antifreeze in the mixture before and after and then solving for the unknown.

Your question deals with the concept of a weight ratio in a chemical mixture. Specifically, we're going to solve it using algebra. Let's say you need x gallons of the 50% antifreeze solution. We can work this out by forming an equation based on the information given in the problem:

The total amount of antifreeze in the 70 gallons of 30% solution and x gallons of 50% solution must be equal to the total amount of antifreeze in the (70 + x) gallons of 40% solution.

Therefore, we can write: 0.3 * 70 + 0.5 * x = 0.4 * (70 + x)

Solving the equation above, we find that x equals 40 gallons. So, you would need to mix 40 gallons of a 50% antifreeze solution with 70 gallons of 30% solution to obtain a final solution with a 40% antifreeze concentration.

The function to represent the growth of the bacteria overtime in your science experiment is:

[tex]y = 70(3^x)[/tex]

Solution:

Given that,

Suppose you are performing an experiment in science class in which you start with 70 bacteria and the amount of bacteria triples every hour

Let,

y is the number of bacteria at time x

x is the number of hour(time)

As per the given information,

You start your experiment with 70 bacteria,and the bacteria triples in every hour

Therefore,

At end of 1 hour,

y = 70 x 3 = 210

At the end of 2 hours,

[tex]y = 210 \times 3 = 630\\\\Which\ can\ also\ be\ written\ as\\\\y = 70 \times 3^2 = 70 \times 9 = 630[/tex]

At the end of 3 hours,

[tex]y = 630 \times 3 =1890 \\\\Which\ can\ also\ be\ written\ as\\\\y = 70 \times 3^3 = 70 \times 27 = 1890[/tex]

Thus at end of "x" hours we will have,

[tex]y = 70 \times 3^x\\\\y = 70(3^x)[/tex]

Thus the function to represent the growth of the bacteria overtime in your science experiment

49 pieces of string can be cut from a ball of string that has 100 feet

Solution:

Given that, Carle is cutting pieces of string that are exactly 24 3/8 inches long

Therefore,

[tex]Length\ of\ each\ string = 24\frac{3}{8}\ inches = \frac{8 \times 24 + 3}{8} = \frac{195}{8}\ inches[/tex]

How many pieces can she cut from a ball of string that has 100 feet

Total length of string = 100 feet

Convert feet to inches

1 feet = 12 inch

100 feet = 1200 inch

Therefore, number of pieces that can be cut is given as:

[tex]\text{Number of pieces } = \frac{\text{total length of string}}{\text{length of each string}}[/tex]

Substituting the values we get,

[tex]\text{Number of pieces } = \frac{1200}{\frac{195}{8}}\\\\\text{Number of pieces } = 1200 \times \frac{8}{195}\\\\\text{Number of pieces } = 49.2307 \approx 49[/tex]

Therefore, 49 pieces of string can be cut from a ball of string that has 100 feet

Correct statements are:

If it is reflected across the y-axis, its length still will be 12 units.

If it is rotated 270° about the origin, its length still will be 12 units.

If it is translated 15 units up, its length still will be 12 units.

Step-by-step explanation:

Whatever it may be rotation, reflection or translation, the size of the line will never change. So length of the line is same as 12 units in the image.

So the wrong statements are

If its reflected across y = -x then the length will no longer be 12 units.

If it is rotated 90° about the origin, then the length will no longer be 12 units.

If it is translated 18 units to the right,  then the length will no longer be 12 units.

You can use the fact that reflection, rotation or translation, all three are not modifying the line itself and only its position can change. Whatever be the position, if the line segment itself isn't modified, the length will be same.

Thus, the correct choices are:

Rest of the choices are wrong since they blame reflection or rotation or translation to modify the length of that line segment.

Suppose you've got a baseball stick. Will it's length change when you take it somewhere else like from your home to playground? No. Will its length change if you hold it upside down? No.

This is the same case with line segment being rotated, reflected, or translated. All these processes do not change the line segment's length and can just move that line segment from one position to other.

Since reflection, rotation, or translation won't affect the length of the line segment,.

Thus, the correct choices are:

Rest of the choices are wrong since they blame reflection or rotation or translation to modify the length of that line segment.

Answer:

Pythagoras’ theorem  is a way to find a side or hypothesis when you have 2 sides.  

The formula is:  a^2 + b^2 = c^2

a and b are sides

c is the hypothesis

Ex:  A triangle has a leg that is 5 inches and a leg that is 7 inches.  Find the hypothesis using Pythagoras' theorem.  

A leg is another way of saying a side.

5^2 + 7^2 = c^2

25 + 49 = x^2

sqrt(74) = sqrt(x^2)

sqrt(74) inches = hypothesis

Ex:  A triangle has a leg that is 9 feet and a hypothesis that is 25 feet.  Find the other leg using Pythagoras' theorem.

9^2 + b^2 = 25^2

81 + b^2 - 81 = 625 - 81

sqrt(b^2) = sqrt(544)

b = sqrt(554)

Step-by-step explanation:

The situation described where the number of miles a car can run depends on the gallons of gasoline in the tank is a relation that is a function. Because for each amount of gas, there is one corresponding maximum distance the car can travel.

The situation described illustrates a relation that is a function. In this case, the amount of gasoline (in gallons) in the car's tank is the input or the independent variable (the domain), and the distance the vehicle can travel (the output or dependent variable) is a function of this input. For each amount of gasoline, there is only one corresponding maximum distance the car can travel, so this is a function. Thus, the best answer is B. A relation that is a function.

Option B: [tex]11,304 \mathrm{mm} ^2[/tex] is the area of the compact disc.

Explanation:

The diameter of the compact disc is [tex]120mm[/tex].

To determine the area of the compact disc, let us substitute the values in the area of the circle formula,

[tex]A=\pi r^2[/tex] where [tex]r=\frac{d}{2}[/tex]

Substituting the value of d in [tex]r=\frac{d}{2}[/tex], we get,

[tex]r=\frac{120}{2} =60[/tex]

Thus, [tex]r=60[/tex] and [tex]\pi=3.14[/tex]. Let us substitute these values in [tex]A=\pi r^2[/tex], we get,

[tex]A=3.14\times(60)^2[/tex]

Simplifying, we have,

[tex]A=3.14\times3600[/tex]

Multiplying, we get,

[tex]A=11304mm^2[/tex]

Thus, the area of the compact disc is [tex]11,304 \mathrm{mm} ^2[/tex]

Hence, Option B is the correct answer.
