Answer: (b>4)÷3

Step-by-step explanation:

A is 3 times as smaller as b which is (b>4)

Answer:

4(x-1)+9=17

Step-by-step explanation:

3(-2x+1) + 5 = 3x-4-5x

expand

-6x + 3 + 5 = 3x-4-5x

-6x + 8 = -2x - 4

add 2x to both sides to put all x values + coefficients on one side

-4x + 8 = -4

subtract 8 from both sides to isolate x and its coefficient

-4x = -12

divide both sides by -4 to isolate x

x = 3

plug x=3 into each option to see if it works

1. 5(3+3)-4 = 30-4 = 26 != 10

2. 2(3+1) = 8 != 4

3. 4(3-1)+9 = 17 = 17

4. 4(3)+7 = 19 != 3+8 = 11

Answer:

Step-by-step explanation:

0.1315 with a bar over all numbers means that the pattern of digits under the bar repeats without end. So the number is 0.1315131513151315131513151315....... etc

There is a formula to kind of simply this but I do not think that is what you are asking for.

Answer:

[tex]\overline{0.1315}=\frac{1315}{9999}[/tex]

Step-by-step explanation:

The trick is that because there are 4 digits being repeated infinitely, then this is equivalent to 1315/9999 because of the four 9s.

A) 15:10

Answer:

Category A      3 1 8

Category B      3 2 1

Step-by-step explanation:

The relative frequency of the columns are:

                             Group 1                 Group 2                Group 3

Category 1                4/11                         1/4                         11/19

Category 2                7/11                         3/4                        8/19.

What is the frequency?

The number of times a specific value appears in the data is its frequency (f). A variable's distribution is its frequency pattern, or the collection of all conceivable values and the frequencies corresponding to those values. Frequency tables or charts are used to represent frequency distributions.

Given table is

                            Group 1                 Group 2                Group 3

Category 1                4                           3                             11

Category 2                7                          9                             8

The frequency of group 1 is (4+7) = 11

The frequency of group 2 is (3+9) = 12

The frequency of group 3 is (11+8) = 19.

The relative frequency is the ratio between the number of times an outcome value appears in the set of all outcomes and the total number of outcomes.

                             Group 1                 Group 2                       Group 3

Category 1                4/11                    3/12 = 1/4                          11/19

Category 2                7/11                     9/12 = 3/4                        8/19.

Answer: It is not possible to determine whether Josh is correct without more information. In order to determine whether they bought the same amount of cheese, it would be necessary to know the weight of the cheeses that Charlie and Josh bought. If the weight of the cheeses that Josh bought is equal to the weight of the cheeses that Charlie bought, then Josh is correct and they did buy the same amount of cheese. However, if the weight of the cheeses that Josh bought is not equal to the weight of the cheeses that Charlie bought, then Josh is incorrect, and they did not buy the same amount of cheese.

Step-by-step explanation: It's hard to say because you would need the weight of the cheese.

Answer:So let's start by guesstimating the slopes:

the green line has a slope close to -x, but more negative than that, possibly -2; the pink line has a slope close to +x, but higher towards +2.

Next let's look at the solution: the two lines intersect at the point (1, -1).

**you could just simple plug that x (1) into all the equations, but let's rule out answers anyway. ;)

A) is incorrect because the slopes of -1 and +1 are off from out predicted -2 and +2

B) is incorrect because of a similar reason, the slopes of +3 and +1 don't make any sense

C) Ooh, we do have a +2 and -2 for the slopes, and... violà! plug in 1 for the x's and we get -1 for the y in both equations

D) slopes are closer than in A and B, but plugging in 1 doesn't get us -1

So the correct answer is:

C) y = 2x - 3 and y = −2x + 1

Answer 64

Step-by-step explanation: if x is 8 you do 8 x 9 which is 72. Then you do 2 x 4 which is 8. So now you have 72 - 8 which is 64.

Answer: Carter will have to ride 3.9 miles on his bicycle every day in order to achieve his goal.

Step-by-step explanation:

Finding the answer to this problem isn't too complicated, and all we have to do is make and solve an equation. First, we know how many miles Carter wants to ride his bicycle (this is what our equation will be equal to), and how many miles he's completed already (we add that to how many he has to do daily). We also know how many days he has left to complete this goal (multiply the number he has to do daily by three).

All we have to do now is construct a basic equation:

17 + 3x = 28.7

Let's move the 17 over to the other side of the equation. To do that, subtract 17 from both sides.

3x = 28.7 - 17

3x = 11.7

This gives us the amount of miles Carter still has to ride - in total. To find out how many miles he has to ride daily, we just divide 3 from both sides.

3x/3 = 11.7/3

x = 3.9 (miles - don't forget the units!)

Carter will have to ride 3.9 miles on his bicycle every day in order to achieve his goal. Hope this helps!

Answer: The volume of box is 6×8×10 cm^3

All of 6,8 and 10 are divisible by 2 so your cubes will fill the box, the volume of the cube is 2×2×2=8 cm^3 divide the volume of the box by 8; number of cubes fitting in the box is 6×10=60

Step-by-step explanation:All of 6,8 and 10 are divisible by 2 so your cubes will fill the box, the volume of the cube is 2×2×2=8 cm^3 divide the volume of the box by 8; number of cubes fitting in the box is 6×10=60

Answer:

50 cubes

Step-by-step explanation:

The maximum number of 2cm cubes that can fit into a box measuring 10cm by 8cm by 5cm is 50 cubes.

You can find this by dividing the total volume of the box (10 x 8 x 5 = 400 cm^3) by the volume of a single cube (2 x 2 x 2 = 8 cm^3). So 400cm^3 / 8cm^3 = 50 cubes.

Hence, The maximum number of 2cm cubes that can fit into a box measuring 10cm by 8cm by 5cm is 50 cubes.

Orleans might have got the answer from subtracting wrong or adding them together.

Hope this helps! :)

Orleans must have chosen C as the correct answer, which is 13/15 hours. This means that Kado spent 13/15 hours longer painting the fence than walking his dog.

To find out how much longer Kado spent painting than walking his dog, we need to calculate the difference between the time he spent painting and the time he spent walking his dog.

Kado spent 1 2/3 hours painting the fence.

He spent 4/5 of an hour walking his dog.

To make the calculation easier, let's convert 1 2/3 hours into an improper fraction:

1 2/3 = (3*1 + 2)/3 = 5/3 hours

Now, the time difference is:

Time spent painting - Time spent walking

= (5/3) - (4/5)

To subtract fractions, we need to find a common denominator, which in this case is 15 (the least common multiple of 3 and 5):

= (5/3)(5/5) - (4/5)(3/3)

= 25/15 - 12/15

Now, we can subtract the fractions:

= (25 - 12)/15

= 13/15 hours

Orleans must have chosen C as the correct answer, which is 13/15 hours. This means that Kado spent 13/15 hours longer painting the fence than walking his dog.
