Answer:

0.20 - $117.76= $16.62

Step-by-step explanation:

if you  have a percentage you can always turn it into a decimal just put the number behind the period: 70% = .70, 49% = .49%       ....

then you do the rest of the equation and BOOM!

20% - $117.76 = $16.62 = 0.20 - $117.76= $16.62.

Answer:

Answer is below

Step-by-step explanation:

20% - $117.76 = $16.62 = 0.20 - $117.76 = $16.62.

or

20 x 100 / 100 - $117.76 = $16.62

Answer:

a, c, d, and f edge 2022 (friend me on disc Stormy#8913)

Step-by-step explanation:

The measures are given as follows:

5. Total area: 2.102 x 10^7 km².

6. Distance between the points: square root of 50 units.

The total area is obtained by the sum of the areas of each sea/ocean, given as follows:

To add two numbers in scientific notation, the bases have to be equal, hence:

1.4056 x 10^7 = 14.056 x 10^6 (multiply the base by 10 and subtract by 1 the exponent.

Hence:

6.963 x 10^6 + 14.056 x 10^6 = 21.091 x 10^6 = 2.102 x 10^7 km².

The coordinates of the points are:

\((x_1,y_1)\) and \((x_2,y_2)\)

The equation for the distance is of:

\(D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

Hence the distance between the points (−5, −3) and (−10, −8) is of:

\(D = \sqrt{(-5 - (-10))^2+(-3 - (-8))^2} = \sqrt{50}\)

Answer:

  5.  (a) 2.1019×10⁷ km²

  14.  (c) √50 units

Step-by-step explanation:

You want the total area of the South China Sea and the Arctic Ocean given their individual areas are 6.963×10⁶ km² and 1.4056×10⁷ km², respectively. And, you want the distance between the points (-5, -3) and (-10, -8).

The sum of the areas of the two bodies of water is ...

  6.963×10⁶ km² +1.4056×10⁷ km² = (0.6963×10⁶ +1.4056) ×10⁷ km²

  = 2.1019×10⁷ km² . . . . . total area

Both of the addends have a precision of 10³ km², so that precision is maintained in the sum.

The distance between the points is found using the distance formula:

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((-10 -(-5))² +(-8 -(-3))²) = √((-5)² +(-5)²) = √(25 +25)

  d = √50

The distance between the points is √50 units.

the meadian score is greater in Judy’s class compared to Ken’s class.

Kens class has a mean score of 83, and Judy's class has a mean score of 86.43(rounded) so, judging by the mean, Judy's class is smarter. If we take a look at the median, (Ken: 84, and Judy: 87) then Judy's class is smarter. So, overall Judy's class is smarter than Ken's class.

Answer: 80%

Step-by-step explanation: IM BAD AT MATH, I JUST LOOKED IT UP. PLEASE HELP ME I HAVE A QUESTION SAVED ON MY ACC. have a great day :D

Answer:

80%

Step-by-step explanation:

percent means per 100 you have to make the denominator 100 the numerator is the percentage

you have to find the decimal

inorder to find the decimal of a fraction you devide the denominator by the number

16 ÷ 20

16/20 is as a decimal is 0.8

after finding the decimal you multiply it by 100

0.8 × 100 = 80

I don't know how else to explain

Answer: The answer is $49.80.

Step-by-step explanation:

First, you set up the equation.

\(\frac{?}{249} = \frac{20}{100} = ?\)    

Now, you have to cross multiply, and divide to solve!

\(\frac{249*20}{100} = \frac{4980}{100} = 49.80\)    This is only the number that could be saved not the actual amount you would get the AirPod Pros for with the 20% discount.

The answer is $49.80.

Step-by-step explanation:

Finding the area of the canvas:

The canvas has sides measuring 3x - 3 and 4x + 1 inches. To find the area, we multiply the lengths of the sides. So, the area of the canvas is given by:

Area = (3x - 3) * (4x + 1)

= 12x^2 + x - 3

Therefore, the correct equation for the area of the canvas is A = 12x^2 + x - 3.

Finding the area of the circle created by the paint:

The rate at which the paint is spreading on the canvas is given by the function r(t) = 4t, where t represents time in minutes and r represents how far the paint has spread. The area of the circle created by the paint can be expressed as A[r(t)] = πr^2, where r(t) is the distance the paint has spread at time t.

Substituting the value of r(t) = 4t into the formula, we get:

A[r(t)] = π(4t)^2

= 16πt^2

Therefore, the area of the circle created by the paint is 16πt^2.

Determining if the circle will be at least 1300 in² in 5 minutes:

To check if the area of the circle will be at least 1300 in² in 5 minutes, we substitute t = 5 into the equation for the area:

A[r(5)] = 16π(5)^2

= 400π

Approximating the value of 400π, we get approximately, 1256.64.

Since 1256.64 is less than 1300, we can conclude that the area of the circle created by the paint after 5 minutes will not be at least 1300 in².

The answer is 8 so its a direct proportion

I think...

The constant of Proportionality is 8.

If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.

Given:

Total Baseball Caps= 30

Total amount of Cap= $240

let the number of caps sold be c.

Then, the equation is

30 c= 240

and, c= 240/30

c= 8

Hence, the constant of Proportionality is 8.

Answer:

Step-by-step explanation:Situation A: The hang glider descended 33.57 feet and again ascended 14.98. So 33.57 - 14.98 = 18.58. So now the hang glider is at 18.58 feet

Situation B: Initially they gained 7 2/5 yards and then lost 3/5 yards.

7 2/5 yards can be written as 37/5. As they lost 3/5 yards, 37/5 - 3/5 = 34/5. So the remaining yards are 34/5 yards.

Situation C: Hiker walked 3 1/6 miles and then 2 1/2 miles. So the total distance is 3 1/6 + 2 1/2 = 5 4/6 miles.

Situation D: Total amount earned is $23.66 + $15.84 = $39.5.

Answer:

\(a=3\text{ and } b=-17\)

Step-by-step explanation:

We are given that:

\(5x^2+bx-12=(5x+a)(x-4)\)

First, we can distribute the right-hand side:

\(5x(x-4)+a(x-4)\)

Distribute:

\(=5x^2-20x+ax-4a\)

Rewrite:

\(=5x^2+(-20+a)x-(4a)\)

Since it is equivalent to the above expression, the coefficients of the variables must match. This means that:

\(-20+a=b\text{ and } 12=4a\)

Solving for a in the second equation gives:

\(a=3\)

Therefore:

\(b=-20+3=-17\)

Answer:

Mean = 33.7

Median = 34.5

Mode = 34

Range = 33

After adding 26....

mean decreases by 0.7

median decreases by 0.5

mode is 34

range is 33

Step-by-step explanation:

mean = sum of all the data values/number of data values

= (18 + 19 + 20  + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7

To find median arrange the values in increasing order, find the mid value

If the number of data points is even, find the average of the mid 2 data values

Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51

Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5

The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once

Mode = 34

The range is highest - lowest = 51 - 18 = 33

After we add 26, we get the following data set arranged

18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51

we can calculate the stats using the same technique as above

We get the following values

mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33  

median = 34

mode = 34

range = 51-18 = 33

To find the decrease in mean and median subtract from the first set of values

Part A: 15x= $810.75. Part B: x= $54.05

The total money earned from 15 tickets is $810.75.

Assume, the money earned from selling 1 ticket is $x.

Therefore, the money earned from selling 15 tickets= 15*x= 15x= $810.75

Here, the variable, i.e. the changing value, is x which is the price of each ticket. The equation hence derived is 15x= $810.75.

Using the equation above,

15x= $810.75.

Dividing both sides by 15,

We get,

x= $54.05

Hence, $54.05 is the price of each ticket.
