Answer:

The second one and the fourth one

Step-by-step explanation:

The second one:

We start off with 3 2/3 yards, and cut it into 4 sections. In other words, it is being divided  into 4 sections.

The fourth one:

There are 4 friends and 3 2/3 pizzas. To equally split it, you divide the amount by 4.

Given parameters:

Quantity of mushroom bought = 4.25pounds

Cost of each mushroom  = $2.99

Unknown:

Best estimate for the cost of the mushroom = ?

Solution:

The cost of the mushroom is:

 Total cost = quantity of mushroom bought x cost of each mushroom

  Total cost  = 4.25 x 2.99

    You can round 4.25 to 4 and 2.99 to 3

                  Or  4 x 3 = $12

62 cm^2

Step-by-step explanation:

the sides are 3*5, 3*2, and 2*5, and there are two of each. 3*5 is 15, 3*2 is 6, and 2*5 is 10.

we need to find 15*2, which is 30, 6*2, which is 12, and 10*2 which is 20. then we need to add all of these together, which is 62

Answer:

If you use 30 instead of 15, that means that  your sum will double

Step-by-step explanation: 30 is double 15

Answer:

its A (12-i)

Step-by-step explanation:

got it right on edge 2020

The complex number with modifying bar will be 12 - i so option (A) will be correct.

Complex numbers are helpful in finding the square root of negative numbers.

A complex number is the sum of a real number and an imaginary number.

The general form of a complex number is a + ib where the first part a called real and the ib is called imaginary.

If we solve x² + 1 = 0 ⇒ x = √(-1) which is called as iota(i).

Bar of complex number = replace i (iota) with - i (iota)

since z = 12 + i

So,

z bar = 12 - i

So 12 - i will be the correct answer to the given question.

Answer:

  9.404 cm

Step-by-step explanation:

A regular polygon with n sides inscribed in a circle of radius r will have a side length given by ...

  s = 2r·sin(180°/n)

For r = 8 and n = 5, this gives a side length of ...

  s = 2·8·sin(180°/5) = 16·sin(36°) ≈ 9.404 . . . cm

Answer: y = -2/3x

Explanation:

This can be determined by calculating the gradient of the straight line, using:

m=ΔyΔx

=−6−34−(−2)

=−96

=−32

Then we use the slope-point form of the straight line:

y−y1=m(x−x1)

to give:

y−3=−32(x−(−2))

∴y−3=−32(x+2)

∴y−3=−32x−3

∴y=−32x

Answer:

Just place a point on (2,-1) and another on (-2,-2)

this should create the line you need

Answer:

You see this is a tricky question but its not that hard if you put your mind to it, but 128 and 100 aren't perfect cubes.

Answer:

Step-by-step explanation:

If either the numerator or a denominator in a fraction is negative, the slope if negative. However, if both the numerator and denominator are negative, it is positive.

The sign of the slope depends on the sign of the numerator and the denominator.

The slope of a line is given by the ratio of the change in the y-coordinate to the change in the x-coordinate between any two points on the line.

If the numerator is positive and the denominator is negative, then the overall sign of the fraction will be negative. Therefore, the slope will be negative.

For example, suppose the numerator is 3 and the denominator is -2. Then, the slope would be:

slope = 3/(-2) = -1.5

This means that the line has a negative slope, which indicates that the line is decreasing as it moves from left to right.

Thus, the slope of a line is negative if it is sloping downwards from left to right, and positive if it is sloping upwards from left to right.

Answer:

Answer- 8 cause 6 x 7 =42 he would need another on

Step-by-step explanation:

Answer:

8 boxes.

Step-by-step explanation:

We have to find out how many times 6 goes into 45.

45/6 = 7.5

Unfortunately, you can't have half a box. To correct this and be able to find the fewest amount of boxes, you simply round to the nearest whole number.

In this case, since the max amount of shirts that can fit in a box is 6, you must round up.

7.5 rounded up is 8.

The fewest amount of boxes you need is 8.

Answer:

y =[tex]-\frac{1}{2}[/tex] x + 5

Step-by-step explanation:

Given parameters:

Coordinates = (-6,2)

Slope  = [tex]-\frac{1}{2}[/tex]

Unknown:

Equation of the line that passes through = ?

Solution:

The equation of a line is expressed as;

        y  =mx + c

y and x are the coordinates

m is the slope

c is the y-intercept

    let us find c;

       2  =  [tex]-\frac{1}{2}[/tex]  x 6 + c

       2  = -3 + c

        c  = 5;

The equation of the line is;

Answer:

$119, $7.

Step-by-step explanation:

First, we need to find the unit rate of pay, in dollars.

Divide $35 by 5 to get $7 per hour.

Now, we multiply the unit rate of pay by 17 to find out how much money is made in the 17 hours that were worked.

By doing this, we get the answer: $119.
