Answer:

4 Hours

Step-by-step explanation:

The original boating fee is $60 then you add $20 per hour so 20 x 4 = 80

80+60=140 $140

Answer: 140=60+20x. He kept the boat for 4 hours

Step-by-step explanation:

x=hours

y=final cost and the final cost is $140

to find x you would use the equation: 140=60+20x

you would first subtract 60 from both sides and you would get:

80=20x

Now you would divide 20 from both sides

So x is 4

Answer:

1,2,4

Step-by-step explanation:

Okay so basically in a triangle, the sum of any two sides should be greater than the third remaining side. So if we had a triangle with sides A, B, and C, A+B>c, A+C>B, and B+C>A. If you look at 1,2, and 4, 1=2=3 which is less than 4. That is why that is not a triangle.

Answer:

x=19

Step-by-step explanation:

50 - 3x = x -26

50-3x-50=x-26-50

-3x=x-76

-3x-x=x-76-x

-4x= -76

x= -76/-4

x=19

Answer:

  b, c, d -- (all but the first)

Step-by-step explanation:

The key take-away regarding what relation is or is not a function is the following: a function has no repeated x-values.

The x-values in the table are -3, -1, 0, 2, so any suggested ordered pair with one of those as an x-value cannot be added to the table. The only such pair in the list is the first one (-3, 4). It cannot be added. All of the remaining three pairs can be added and the relation will remain a function.

Answer:

Answer: Betty should prepare all 60 cookies. Each cookie will receive a number. The numbers will be written on slips of paper, put into a hat, and shuffled well. The first 15 numbers drawn will indicate the cookies to be baked at 300°, the next 15 will indicate the cookies to be baked at 325°, and so on until all 60 cookies are allocated.

Step-by-step explanation: I just got it correct on Edge :)

The true option about the randomized design is (c) Betty should prepare all 60 cookies. Each cookie will receive a number. The numbers will be written on slips of paper, put into a hat, and shuffled well. The first 15 numbers drawn will indicate the cookies to be baked at 300°, the next 15 will indicate the cookies to be baked at 325°, and so on until all 60 cookies are allocated.

The given parameters are:

[tex]\mathbf{n = 60}[/tex]

[tex]\mathbf{Batches = 4}[/tex]

[tex]\mathbf{Cookies= 15}[/tex] ---- the number of cookies in each batch

[tex]\mathbf{Temperature= 300,325,350,375}[/tex]

To randomly assign the cookies to the given temperatures, all cookies have to be subjected to the same conditions (except the difference in the temperature).

This means that, she can bake all the cookies at once at different temperatures, while noting down the cookies with a given number.

Hence, the true option is (c)

Answer:

5 is the median

Step-by-step explanation:

Median

Arrange your numbers in numerical order.

Count how many numbers you have.

If you have an odd number, divide by 2 and round up to get the position of the median number.

If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

x^2=25

x=5

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

here's your solution

=> x^2 + 5 = 30

=> take constant to right side

=> x^2 = 30 - 5

=> x^2 = 25

=> now take square to right side it will be

converted into root

=> x = √25

=> x = 5

Answer:

23 x-29y=98.......(1)

29 x-23y=110.......(2)

adding (1) and (2)we get

52 x-52y=208

52(x+y)=208

x-y=4...(3)[we get four by dividing 208 with 52]

subtract (2) from (1) we get

-6 x-6y=-12

x-y=2.....(4)

adding (3) and (4) we get

2x=6

therefore x=3

now from (4) we get

x-y=2 [we substitute xfor 3]

3-y=2

y=2-3

y=-1( that is the answer for your first question)

Step-by-step explanation:

99x+101y=499.....(1)

101x+99y=501.....(2)

add (1) and (2)

(99+101)x+(101+99)=(499+501)

200x+200y=1000

200(x+ y)=1000

x+y=5.....(3)

subtract (2)from(1) we get

2x-2y=2

2(x-y)=2

x+y=1.......(4)

x+y=5

x-y=1(add them together)

2x=6

x=3

substitute x equal to 3 in equation (3)

x+y=5

3+y=5

y=2

y equal to 2 and x equal to 3

Answer:

£ 105.

Step-by-step explanation:

Since it is required to decrease £ 120 by 12.5%, to perform this subtraction the following mathematical operation must be performed:

100 - 12.5 = 87.5

100 = 120

87.5 = X

87.5 x 120/100 = X

10,500 / 100 = X

105 = X

Thus, decreasing £ 120 by 12.5% you get a total of £ 105.

Answer:

Using the Pythagorean Theorem we can see that:

[tex]9^2+40^2=1681\\\sqrt{1681}=41[/tex]
