2/5k - 3/5 + 1/10k ?

Answers

Answer 1

Answer:

Since it is not an equation u wont get a numerical value

so basically its just fraction addition and subtraction

which is ((2/5)-(3/5)+(1/10))k

so answer is (-1/10)k

Answer 2

Step-by-step explanation:

[tex] \frac{2}{5} k \: - \frac{3}{5} + \frac{1}{10} k[/tex]

[tex] \frac{4}{10} k + \frac{1}{10} k - \frac{3}{5} [/tex]

[tex] \frac{5}{10} k - \frac{3}{5} [/tex]

[tex] \frac{k}{2} - \frac{3}{5} [/tex]

A circular disc has an area that measures between 1,650 and 1,700 square inches. What could be the length of its radius? Use 3.14 for . 23 in. 24 in. 25 in. 26 in.

Answers

Answer:

23 in

Step-by-step explanation:

We know the area of the circular disc is A = πr² where r = radius and π = 3.14.

So, r = √(A/π)

Now, if A = 1650 square inches,

r = √(A/π)

= √(1650 in²/π)

= √525.48 in²

= 22.92 in

≅ 22.9 in

Also, if A = 1700 square inches,

r = √(A/π)

= √(1700 in²/π)

= √541.40 in²

= 23.27 in

≅ 23.3 in

If the area is between 1650 in² and 1700 in², that is 1650 in² < A < 1700 in²

then, the radius is between 22.9 in < r < 23.3 in.

Since the left and right side of the inequality are approximately 23 in, the radius of the circular disc is 23 in.

The length of the radius of the circular disc is approximately is 23 in.

Hence, option A)23 in is the correct answer.

What is a circle?

A circle is simply a closed 2-dimensional curved shape with no corners or edges.

The area of a circle is expressed mathematically as;

A = πr²

Where r is radius and π is constant pi ( π = 3.14 )

Now, if the area of the circular disc is 1650in², the radius r will be;

A = πr²

1650in² = 3.14 × r²

r² = 1650in² / 3.14

r² = 525.4777in²

r = √( 525.4777in² )

r = 22.9in

Also, if the area of the circular disc is 1700in², the radius r will be;

A = πr²

1700in² = 3.14 × r²

r² = 1700in² / 3.14

r² = 541.40127in²

r = √( 541.40127in² )

r = 23.3in

Next we take the average of the two radii

Radius = ( 22.9in + 23.3in )/2 = 46.2/2 = 23.1 ≈ 23 in

The length of the radius of the circular disc is approximately is 23 in.

Hence, option A)23 in is the correct answer.

Find the value of x and y

Answers

Answer:

y = 23

x = 28

Step-by-step explanation:

Find y first.

3y + 5y - 4 = 180                     The two angles are supplementary if the all the lines are parallel.  Combine the left side.

8y - 4 = 180                              Add 4 to both sides

8y - 4 + 4 = 180 + 4

8y = 184                                   Divide both sides by 8

y = 23

====================================

Now if the lines are parallel, then 3y = 2x + 13

But we already know y

3*23 = 2x + 13                         Do the multiplication

69 = 2x + 13                             Subtract 13

56 = 2x                                    Divide by 2

x = 56/2

x = 28

Answer:

y = 23

x = 28

(05.05) Which of the following inequalities matches the graph? (1 point)​

Answers

Answer: Choice C.  [tex]y \ge -1[/tex]

==========================================================

Explanation:

The boundary line is a solid line and it's horizontal. Every point on the boundary line has y coordinate -1. So y = -1 is the equation of the boundary line. We can write it as y = 0x-1.

The shading is above the boundary line, so the inequality is [tex]y \ge -1[/tex]

Any point (x,y) in the shaded region has y coordinate that is y = -1 or greater.

For example, the point (0,2) in the shaded region has y coordinate y = 2, and it satisfies the inequality [tex]y \ge -1[/tex] because [tex]2 \ge -1[/tex] is a true statement.

Note: the boundary line is solid, so any point on the boundary line is part of the shaded solution set. This is due to the "or equal to" as part of the inequality sign.
