Answer

well if dora earns a monthly salary of $3,568 and she gives boots $1189 and gives swiper the fox $1189 and keeps $1189 for herself that she can buy starbucks and clothes

Step-by-step explanation:

Answer:

3,694.71 dollars

Step-by-step explanation:

Given the following question:

Dora earns a monthly salary of $3,568...
She also earns a 1% commission...
Last month she sold $12,674 worth of products

To find the answer we have to find 1% of her last month's pay and then add that number to her monthly salary.

1% of $12,674
[tex]\frac{1\times12674}{100} =1\times12674=12674\div100=126.74[/tex]
1% of $12,674 is $126.74
[tex]3568+126.71=3694.71[/tex]
The number is already rounded to the nearest hundredth's place.
[tex]=3694.71[/tex]


So, in total Dora earns "$3,694.71" for last month.

Hope this helps.

Answer:

32 pints

Step-by-step explanation:

4 gallons * 8 pints/1 gallon = 32 pints

d=18h

18=18h

Therefore, he only needs to babysit one hour before he can get 18 dollars

If y = x² - 1, then y + 1 = x² and y' = 2x. Then in the DE, we would have

2x = - (x² - 1) x² / x   ⇒   2 = - x² + 1

but this only true for some values of x. So the first choice is not correct.

If y = 2/(x - 2), then y + 1 = x/(x - 2) and y' = -2/(x - 2)². In the DE,

-2/(x - 2)² = - (2/(x - 2)) (x/(x - 2)) / x   ⇒   -2/(x - 2)² = -2/(x - 2)²

so the second choice is the correct answer.

Answer:

speed of the plane = 190 mph

Step-by-step explanation:

Let x = speed of the plane, then speed of the car = x - 150

time = 200/(x - 150) = 950/x

Divide by 50 on both sides, get

4/(x - 150) = 19/x

Cross multiply:

4x = 19(x - 150)

4x = 19x - 19*150

15x = 19*150

x = 19*150/15 = 190

Answer:

option A is the answer because -4/3 is both negative and reciprocal of 3/4

Answer:

A. 3/4 & -4/3

Step-by-step explanation:

Negative reciprocal is the negative of the value and the numerator/denominator is switched to denominator/numerator.

For example, -7/15.

-7 is the numerator because -7 is above 15. But if we switch that, it will become -15/7. If we turn it from negative to positive or positive to negative, which in this case is negative to positive, since negative x negative is positive, it will become 15/7. I really took the time to explain this, so I hope this helps. =D

Answer:

85 km

Step-by-step explanation:

to find this answer you must use the pythagorean theorem

this formula is basically a^2 + b^2 = c^2

so square the two sides that you have and thats the answer of the hypotenuse squared

68^2 + 51^2 = c^2

4624 + 2601 = 7225

then you must take 7225 to the square root

that is 85

Answer:

5 cm

Step-by-step explanation:

Use the Pythagorean Theorem. a and b are legs, so a = 3 and b = 4. c is the hypotenuse.

[tex]a^{2} +b^{2} = c^{2} \\3^{2} + 4^{2} = c^{2} \\9 + 16 = c^{2} \\25 = c^{2} \\\sqrt{25} = \sqrt{c^{2} } \\c = 5[/tex]

Answer:

Step-by-step explanation:

ratio of out of state fans to total number of fans:

640 : 1580 = 640/1580 = 32/79

So 32 out of every 79 fans were out of state fans

Answer:

A) 32 out of every 79 fans attending were out-of-state fans

Step-by-step explanation:

640 were out-of-state fans :  1,580 fans in the game

32 were out-of-state fans : 79 fans in the game

✔A) 32 out of every 79 fans attending were out-of-state fans

B) 47 out of every 79 fans attending were out-of-state fans

C) more than 47 out of every 79 fans attending were out-of-state fans

D) at least 32 out of every 79 fans attending were out-of-state fans

Answer: if you’re asking for the missing angle then it’s 125°

Step-by-step explanation:

triangles always equal 180°

i’m assuming 25° and 30° are the other angle measures so

25° + 30° = 55°

180° - 55° = 125°

so the missing angle is 125°

hope this helps :)

Probability distributions can be represented using tables and graphs

The probability table is given as:

x              0       1        2       3      4

P(x) -> 0.191 0.319 0.287 0.128 0.074

The above table means that:

P(0) = 0.191

P(1) = 0.319

P(2) = 0.287

P(3) = 0.128

P(4) = 0.074

Next, we check if the table represents a probability distribution using:

[tex]\sum P(x) = 1[/tex]

So, we have:

[tex]\sum P(x) = 0.191 + 0.319 + 0.287 + 0.128 + 0.074[/tex]

[tex]\sum P(x) = 1[/tex]

The graph is not given. So, I will plot the graph
