Answer:

(4)($3)

Step-by-step explanation:

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

Answer:

Answer:

7. y

/2

x  +  4

8.  y= (0,4)

Step-by-step explanation:

7. the slope is -1/2 and the y intercept is 4

8. so basically, the y intercept is when y is zero, which makes this one (0,4)

Answer:

2916

Step-by-step explanation:

[tex] {(54)}^{2} \\ \\ = ( {50 + 4)}^{2} \\ \\ = {(50)}^{2} + {(4)}^{2} + 2 \times 50 \times 4 \\ \\ = 2500 + 16 + 400 \\ \\ = 2916[/tex]

Answer:

x=4

Step-by-step explanation:

distribute first 3x+18-13=17

combine like terms 3x+5=17

subtract 5 from both sides 3x=12

divide 3 from both sides x=4

Answer:

-5/6

Step-by-step explanation:

Use slope intercept form: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\frac{-2-8}{20-8}[/tex] = [tex]\frac{-10}{12}[/tex] = -5/6

Answer:

k=88

Step-by-step explanation:

as 8*11=88

Answer:

k = 88

Step-by-step explanation:

Given

[tex]\frac{k}{8}[/tex] = 11 ( multiply both sides by 8 to clear the fraction )

k = 88

Answer:

x = 3

Step-by-step explanation:

32 * 2^x = 2^8

32 * 2^x = 256

divide 32 from both sides

2^x = 8

then solve for x

2^3 = 8

Answer:

205......

Step-by-step explanation:

maybe i tried.

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:

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.

GH = [tex]\sqrt{26}[/tex]

Step-by-step explanation:

Answer:  Please look at the steps to see the answers.

Step-by-step explanation:

The line y= 2 has a slope of 0 meaning that for any input of x  the results will always be 2.

This means the the graph will be a horizontal line through the point, (0,2)

You can also use this table to graph it;

Answer:

i. 5(x + 0.2x) yards

ii. 6x yards

Step-by-step explanation:

Since the requested quilts are 20% larger than the normal pattern, then;

20% of x = 0.2 x

Thus,the yards of material to make each of the requested quilts increased by 0.2x yards.

So that;

To make one of the requested quilt, the yards required = x + 0.2x

For 5 requested quilts, the total yards required = 5(x + 0.2x)

Total yards of material for the requested quilts is 5(x + 0.2x).

Also,

5(x + 0.2x) = 5x + 5(0.2x)

                  = 5x + x

                  = 6x

Thus, the total yards required is 5(x + 0.2x) or 6x.

Here is your answer and an explanation

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:

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.
