The perimeter of quadrilateral ABCD is 85. Find the value of x.

Answer:

about 21 kids out of 170 are expected to be nearsighted (20:170)

Step-by-step explanation:

we find 12% out of 70 by muliplying 170 x 0.12 which equals 20.4

However it has to round up because we cant have half a child so 21 children.

Answer:

y=-x+2, y=1/3x+2

Step-by-step explanation:

1) the y intercept is at 2, the slope is -1

2) the y intercept is at 2, the slope is 1/3

Answer:

m = 5 is the answer

Step-by-step explanation:

use symbolab I use it all the time

Answer:

the slope is 5

Step-by-step explanation:

the formula is y=mx+b and in this case 5 is m which stands for the slope

Answer: 138

Step-by-step explanation:

It’s slightly bigger than 90, so go with D, 138 degrees because 138 is 90 + 48. 48 is slightly more than 45, which is half of 90. 4 looks about 90 plus half of 90.

Answer:

[tex]176\ \text{ml/hr}[/tex]

[tex]58.08\ \text{mL/hr}[/tex]

[tex]11\ \text{gtt/hr}[/tex]

[tex]638.88\ \text{mg}[/tex]

Step-by-step explanation:

33 ​% dextrous solution ​( 33 mg per 100 mL of​ solution)

1.936 L of the solution is given over an 11-hour period

So the flow rate in mL/hr is

[tex]\dfrac{1.936\times 10^3}{11}=176\ \text{ml/hr}[/tex]

The flow rate in ml/hr is [tex]176\ \text{ml/hr}[/tex]

Flow rate of dextrous in mL/hr is

[tex]0.33\times 176=58.08\ \text{mL/hr}[/tex]

The flow rate dextrous in mL/hr is [tex]58.08\ \text{mL/hr}[/tex]

Each mL contains 16 drops​ so flow rate in gtt/h is

[tex]\dfrac{176}{16}=11\ \text{gtt/hr}[/tex]

The flow rate in units of​ gtt/hr is [tex]11\ \text{gtt/hr}[/tex]

The mass of dextrous delivered 11 hours in mg is

[tex]0.33\times 1.936\times 10^3=638.88\ \text{mg}[/tex]

The mass of dextrous delivered 11 hours in mg is [tex]638.88\ \text{mg}[/tex]

Answer:16.7

Step-by-step explanation:subtract 63.5 by 46.8 and you will get 16.7 degrees fahrenheit

If Friday and Saturday have such a temperature of 46.8 and 63.5 degrees Fahrenheit, respectively. Saturday's temperature is 16.7 degrees Fahrenheit lower than Friday's.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

In mathematics, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.

It is given that the temperature in a city on a Friday was 46.8 degrees Fahrenheit. On Saturday, the temperature was 63.5 degrees Fahrenheit.

The temperature on Saturday is how much less than the temperature on Friday found as,

= 63.5 - 46.8

= 16.7° F

Thus, If Friday and Saturday have such a temperature of 46.8 and 63.5 degrees Fahrenheit, respectively. Saturday's temperature is 16.7 degrees Fahrenheit lower than Friday's.

Answer:

10

Step-by-step explanation:

The mean for the set of data 6, 7, 10, 12, 12, and 13 is 10.

The arithmetic mean is defined as the ratio of the sum of observations to the total number of observations.

The formula for the mean of a given set of data is as follows:

Mean = Sum of Observations/Total number of observations

Given the set of observations as:

{6, 7, 10, 12, 12, 13}

To determine the mean of a set of data, add up all the numbers and divide by the total number of numbers.

So, for the given set of data:

Mean = (6 + 7 + 10 + 12 + 12 + 13) / 6

Mean = 60 / 6

Mean = 10

Therefore, the mean for the given set of data is 10.

Answer:

Step-by-step explanation:

Answer:

Expected value of the game is $1.75

Step-by-step explanation:

The probability of getting a head or a tail on flipping a coin is 1/2 and so the probability of winning is 1/2 as we need all heads or all tails . There are 3 fair coins so the expected value of winning is given by =

P(1st coin =x =head)= 1/2

P(2nd coin =x =head)= 1/2

P(3rd coin =x =head)= 1/2

P(1st coin =x =tail)= 1/2

P(2nd coin =x =tail)= 1/2

P(3rd coin =x =tail)= 1/2

E(X= win) = ∑xP(x)=  (1/2)³+(1/2)³= 1/8 + 1/8= 2/8

Expected value of winning the game is $ 7*2/8= 14/8=$ 1.75

$ 1.75- $1= $ 0.75

$ 0.75 (8) = $ 6

This means that for a total of $ 8  he gets $ 6.

Answer:

2,482 fishes will be in the pond after 5 months

Step-by-step explanation:

First, let us model an equation that is used to determine the fish population after n months:

Let the initial population of the fishes = P₀

Let the population after n months = Pₙ

percentage increase each month = 7%

[tex]P_n = P_{n-1} + 7 \%P_{n-1}\\P_n = P_{n-1} + 0.07P_{n-1}\\P_n = (1.07)P_{n-1}[/tex]

Next, we are told that 300 fishes are lost each month, therefore, the population after n months is given by:

[tex]P_n = (1.07)P_{n-1} - 300[/tex]

Therefore population after 5 months:

n = 5

[tex]P_5 = (1.07)P_{5-1} - 300\\P_5 = (1.07)P_4 - 300[/tex]

[tex]Remember\ P_0 = 3000\\starting\ at\ P_1\\P_1 = (1.07)P_0 - 300\\P_1 = (1.07)(3000) - 300\\P_1 = 3210 - 300 = 2910\\P_2 = (1.07)P_1 - 300\\P_2 = (1.07)(2910) - 300 = 2813.7\\\\P_3 = (1.07)(2813.7) - 300\\P_3 = 3010.66 - 300 = 2710.66\\\\P_4 = (1.07)(2710.66) - 300 = 2600.40\\\\P_5 = (1.07)(2600.40) - 300 = 2482.4\\[/tex]

Answer:

40(.50) + 200(.25) = 20 + 50 = $70

Step-by-step explanation:

40(.50) + 200(.25) = 20 + 50 = $70

Answer:

$60

Step-by-step explanation:

20 half dollars means that there's 10 dollars in it (because you divide 20 by 2 since 2 half dollars make one dollar)

It takes 4 quarters to make one dollar and if there's 200 quarters then there's 50 dollars in it (200 divided by 4 is 50)
