D (2+3/7)+4/7
(I'll give brainliest for the correct and most accurate answer.)

Answers

Answer 1

Answer:

D. (2 + 3/7) + 4/7

Step-by-step explanation:

In B and C, the numbers involved in expressions are integers.

Hence, they can be easily added or subtracted.

In D, the numbers involved in expression are fractions which are not grouped together.

They can be added but by using associative property, it becomes much more easier.

That is, grouping fractions.

The function f(x) is shown on the graph.

On a coordinate plane, a curved line with 3 arcs, labeled f of x, crosses the x-axis at (negative 2, 0), (negative 1, 0), (1, 0), and (3, 0), and the y-axis at (0, negative 6).

What is f(0)?

Answers

Given :
On a coordinate plane,a curved line with 3 arcs, lab led f of x, crosses the x-axis at (negative 2,0), (negative 1,0), (1,0), and (3,0) and the y axis at (0, negative 6).

To find:
f when x = 0. i.e. f (0).

Solution:
since the graph has 3 arcs and 4 solutions, it can be visualized as the follows:
Between each solution, the function has to increase and decrease giving arcs in between.
1. One of the arcs is between (negative 2,0) and negative (1,0)
2. Second arc is between (negative 1,0) and (1,0)
-this arc cuts the y axis, since x= 0 lies between x= -1 & x=1-
3. Third arc is between (1,0) and (3,0)
Therefore only the 2nd arc cuts the y axis
It’s given that the curve cuts the y axis at (0, -6)
That is when x= 0, f(0) =-6
Therefore the value of f (0) is -6 only.

steps to the answer of 1/3(n+6)=−10?

Answers

Answer: n=−36

Step-by-step explanation: When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 n+36

 ———— • 3 = 0 • 3

  3  

Now, on the left hand side, the  3  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  n+36  = 0

 Solve  :    n+36 = 0  

Subtract  36  from both sides of the equation :  

                     n = -36

1. Distribute to clear out parentheses
2. Subtract 2 from both sides
3. Multiply by 3 on both sides

1. considering that there are 16 ounces in one pound, and the question is asking for one pound, I would think that there would only need to be 16 ounces observed.

2. Through calculations of the given number of oz, there are 71 calories per oz. By multiplying that by 16 (the number of oz in a lb) there are a total of 1,136 calories in a lb.

Step-by-step explanation:

Working days : 5

Working hours : 3.5 + 4 = 7.5 Hours

Earning in a day = 7.5 * 18.75 = 140.625

Earning in the week (working days only): 140.625 * 5 = 703.125

According to the problem,

Mrs. Rodriguez worked 5 days last week. She worked 3.5 hours before and 4 hours after lunch. Mrs. Rodriguez earned $18.75 per hour.

Total hours of work = (3.5 + 4) hours = 7.5 hours in one day

In 5 days she worked (7.5 x 5) hours = 37.5 hours

In the last week Mrs. Rodriguez worked 37.5 hours.

Amount of money she earned =  $ (37.5 x 18.75) = $703.125

Answers

Using the multiplication operation, the Number of ergs produced in [tex]1.55 \times 10^{7} [/tex] is [tex] 6.045 \times 10^{40} \: ergs [/tex]

Eggs produced per second = [tex]3.9 \times 10^{33} [/tex]

Number of seconds = [tex]1.55 \times 10^{7} [/tex]

Total number of ergs produced can be calculated thus :

Ergs per second × number of seconds

[tex]3.9 \times 10^{33} \times 1.55 \times 10^{7} = 6.045 \times 10^{33+7} = 6.045 \times 10^{40} \: ergs [/tex]

Therefore, the Number of ergs produced in [tex]1.55 \times 10^{7} [/tex] is [tex] 6.045 \times 10^{40} \: ergs [/tex]

Due to the very small measure of the diameter of the human hair, a measure of [tex]1.8 \times 10^{2} mm[/tex] would be too large, Hence, the value [tex]1.8 \times 10^{-2} mm[/tex] would be more appropriate
