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:

1092 cm^2

Step-by-step explanation:

Formula = 2 * Height (Length + Width)

2 * 26 (15 + 6) = 1092

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:

the second and third one

Step-by-step explanation:

Answer:

Given that angle DGC is 90 degrees and is vertical to AGB, they both are congruent so they will both have the same degrees.

So now we know angle AGB is 90 degrees

Angle AGE is 30 degrees, and in total all the angles would be equal to 180 degrees.

Now we just solve for x,

30 + 90 + x = 180

120 + x = 180

-120      -120

x = 60

The given data are the scores turned in by the amateur golfer, from

which the sample standard deviation can be calculated.

Responses:

The mean and sample standard deviation for the 2017 season are;

The mean and sample standard deviation for the 2018 season are;

The mean is given by the formula;

[tex]\overline x= \mathbf{\dfrac{\sum \left x_i }{N}}}[/tex]

N = 8

The mean for the 2017 season is therefore;

[tex]\overline x[/tex] = (72 + 76 + 77 + 75 + 73 + 71 + 73 + 75) ÷ 8 = 74

The sample standard deviation is given by the formula;

[tex]s =\mathbf{\sqrt{\dfrac{\sum \left (x_i-\overline x \right )^{2} }{N -1}}}[/tex]

[tex]\sum \left (x_i- \overline x \right )^2[/tex] = 30

N = 8

The sample standard deviation for 2017 season is therefore;

[tex]\sigma =\sqrt{\dfrac{30}{8-1}} \approx \mathbf{2.07}[/tex]

The mean and sample standard deviation for the 2017 season are;

The mean for the 2018 season is found as follows;

[tex]\overline x[/tex] = (62 + 68 + 73 + 75 + 83 + 78 + 83 + 78) ÷ 8 = 74

The sample standard deviation is given by the formula;

[tex]s=\mathbf{\sqrt{\dfrac{\sum \left (x_i-\overline x \right )^{2} }{N - 1}}}[/tex]

[tex]\sum \left (x_i- \overline x \right )^2[/tex] = 194

N = 8

The sample standard deviation for 2018 season is therefore;

[tex]Standard \ deviation \ for \ the \ 2018 \ seaon, \sigma =\sqrt{\dfrac{194}{8 - 1}} \approx \mathbf{5.26}[/tex]

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.

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°

Answer:

I'll do the first one as an example. The answer of the first one is 6.

Step-by-step explanation:

In the first example, they multiplied the number by 2 to get a common denominator for the two fractions so you can easily add. So, the first box will come 10 (5 times 2) and the second box will become 2 (1 times 2). Then simply add the fractions. The sum of the first question is 2. Because 2 10/12 + 3 2/12 = 6. Remember to add only the whole numbers and fractions. If you want, you can try using mathaway for additional help.

Answer: 17.5 lbs of plums are required to make 20 rolls of fruit leather.

Step-by-step explanation:

Since 7 lbs of plums yield 8 rolls of fruit leather, 1 lb will yield 1 1/7 rolls of fruit leather.

To find how many pounds of fruit will yield 20 rolls of fruit leather, divide how many rolls of leather you want to get by how many rolls of leather one pound will yield.

20 divided by 8/7 equals 17 1/2.

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

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

Answer:

Step-by-step explanation:

Each of the given equations describes a line on a graph. There are numerous ways to find the values of x and y that will satisfy both equations at the same time. Two of them you have seen are "substitution" and "elimination." Here, "substitution" is easily accomplished by equating one expression for y to the other expression for y:

  y = y

  100 +65x = 40 +80x . . . substitute for y

  60 +65x = 80x . . . . . . . subtract 40 from both sides

  60 = 15x . . . . . . . . . . . . subtract 65x from both sides

  4 = x . . . . . . . . . . . . . . divide both sides by 15

  y = 40 +80x = 40 +80(4) = 360 . . . . find the value of y

The values of x and y that satisfy both equations are ...

  (x, y) = (4, 360)

__

The point (4, 360) is on both lines. That is the point where the lines intersect. It means 4 hours work will cost $360 in either shop.

__

The time of 4 hours that we found above is the "break-even" or "crossover" point in the cost equations. For times below that point, the lowest cost comes because of the lowest "service charge". For times above that point, the lowest cost comes because of the lowest per-hour charge.

3 hours is less than 4 hours, so the shop with the lowest service charge will have a lower cost. That is Amy's shop. Her price for 3 hours is ...

  40 +80(3) = 40 +240 = $280 . . . for 3 hours work in Amy's shop

__

If you want to make sure of that, you can find the cost in Mike's shop:

  y = 100 +65(3) = 100 +195 = $295 . . . for 3 hours in Mike's shop

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.
