The estimate of the sum by rounding each number to the nearest tenth is 0.8

Estimation is a method used for calculating the approximate value of a quantity (just to get a 'rough answer')

In estimation 1, 2,3, and 4 are rounded down while 5, 6, 7, 8 and 9 are rounded up.

Rounding each number to the nearest tenth:

0.214 = 0.2

0.61 = 0.6

The sum = 0.2 + 0.6 = 0.8​

-3x+12  choice A

Answer:

[tex]\huge\boxed{f^{-1}(x)=4x+48}[/tex]

Step-by-step explanation:

In order to find the inverse of a function, we need to follow a couple of steps.

We can follow these steps to find the inverse of this function.

Step 1: We can just replace the f(x) with y, making our function [tex]y=\frac{1}{4}x-12[/tex].

Step 2: We can swap where the x and y values are, making our equation

[tex]x = \frac{1}{4}y-12[/tex]

Step 3: We can now solve for y.

We now have the function as [tex]y = 4x+48[/tex].

Step 4: We can now replace the y with [tex]f^{-1}(x)[/tex].

[tex]f^{-1}(x) =4x+48[/tex]

Therefore the inverse of [tex]f(x) = \frac{1}{4}x-12[/tex] is [tex]f^{-1}(x) =4x+48[/tex].

Answer:

bar graph??? we need a pic

The requried table that represents the bar graph is table H.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
The total number of students is 30,

Now,

10% of students take lunch,
So the number of students who take lunch,
= 10% of 30
= 3

Similarly,

Number of students who takes Breakfast = 9
Number of students who takes super = 18

Thus, the requried table that represents the bar graph is table H.

Your welcome

Answer:

Yen is the currency of Japan

Answer:

9,000

Step-by-step explanation:

You would add it together.

6107 + 2960 = 9,067

You round the thousand (9) to the 0.

The rule is that if any number next to the one your rounding is higher then 5 or is 5 then the rounding number will go up, if its 4 or below if won't go up but stay the same.

9,067 would not go up but stay the same because of the rule.

Estimations are guesses from the mind so an exact answer wouldn't work but its whatever.

Answer:

interior angle of a hexagon = 720

straight line is a 180 degree angle.

180- 116 = 64

a=64

180- 82 = 98

116 + 98 + 90 = 304

720 - 304 = 416

416/3 =138.666666

b=138.666666

Answer:

2 stickers

Step-by-step explanation:

We multiply his 7 friends by 8 (stickers given to each friend) to get 56 stickers given total.

We subtract 56 from 58 to get 2 stickers remaining for Justin.

Step-by-step explanation:

Justin is giving out 8 stickers to 7 of his friends

To find out how many stickers he passed out, you would need to do 7×8

7×8 = 56

Now you want to subtract 56 from 58 to figure out how many stickers he had left

58 - 56 = 2

Justin is left with 2 stickers

Answer:

  an = -7(1/3)^(n-1)

Step-by-step explanation:

The explicit formula for a geometric sequence with first term a1 and common ratio r is ...

  an = a1·r^(n-1)

The multiplier in the recursion relation is the common ratio: 1/3. The first term is given as a1 = -7. Putting these in the general formula, we have ...

  an = -7·(1/3)^(n-1)

Answer: 417

Step-by-step explanation:

Since the digit in the ones place is the fourth odd number that the person count beginning with 1, then the digit will be 7.

This means the number will be:

____ _____ 7. The number in the units and hundreds place are still unknown. But since the addition of the three numbers gives 12, and approximating to the nearest hundred gives 400. Then the number will be 417.

Check: 4 + 1 + 7 = 12

417 = 400 to nearest hundred

Answer:

n = -7

Step-by-step explanation:

49 = -5n - 2n

combine like terms

-5 - 2 = -7

49 = -7n

divide both sides by -7

49/-7 = -7n/-7

49/-7 = n

49/-7 = -7

-7 = n

Answer: 6 Containers are needed

Step-by-step explanation:

The ideal number of Kanban cards can be calculated using the following formula;

N = (DT × ( 1 + X)) / C

where N is total number of container,

D is panned usage rate of using work Centre

T is Average waiting time for replenishment of parts plus average production for a  container of parts,

X is policy variable set by management that reflects possible inefficiency in the system ,

C is capacity of standard container.

Now, given that;

D = 105 parts

T = 90min = 90/60 = 1.5 hrs

X = 0.35

C = 3 × 12parts = 36 parts

so; we substitute

N = (105×1.5 × ( 1 + 0.35)) / 36

N = 212.626 / 36

N = 5.9063 ≈ 6

Therefore 6 Containers are needed

Answer:

[tex]H = 5200[/tex] - Hypotenuse

[tex]S_1 = 2000[/tex] - Leg 1

[tex]S_2 = 4800[/tex] - Leg 2

Step-by-step explanation:

Represent the dimensions as:

[tex]H = Hypotenuse[/tex]

[tex]Other\ Legs = \{S_1,S_2\}[/tex]

So, we have:

[tex]S_1 = 2000[/tex]

[tex]H = 400 + S_2[/tex]

Required

Determine the dimensions

Apply Pythagoras theorem

[tex]H^2 = S_1^2 + S_2^2[/tex]

This gives:

[tex](400 + S_2)^2 = 2000^2 + S_2^2[/tex]

Open bracket

[tex]160000 + 800S_2 + S_2^2 = 4000000 + S_2^2[/tex]

[tex]160000 + 800S_2 = 4000000[/tex]

Collect Like Terms

[tex]800S_2 = 4000000 - 160000[/tex]

[tex]800S_2 = 3840000[/tex]

Solve for S2

[tex]S_2 = \frac{3840000}{800}[/tex]

[tex]S_2 = 4800[/tex]

Recall that:

[tex]H = 400 + S_2[/tex]

[tex]H = 400 + 4800[/tex]

[tex]H = 5200[/tex]

Hence, the dimensions are:

[tex]H = 5200[/tex]

[tex]S_1 = 2000[/tex]

[tex]S_2 = 4800[/tex]
