Please check the graph of a number line is also attached below.

Step-by-step explanation:

Given the inequality

[tex]6h+26\:\ge \:\:80[/tex]

solving inequality

[tex]6h+26\ge \:80[/tex]

subtract 26 from both sides

[tex]6h+26-26\ge \:80-26[/tex]

[tex]6h\ge \:54[/tex]

Divide both sides by 6

does 3/7 , 12/21 make a proportion

Answers

Yes it does hope this helps

Answer:

No, it does not.

Step-by-step explanation:

The question, does 3/7 and 12/21 make a proportion, does not. It does not make a proportion, because for 3 to equal 12, you must multiply by four. when you multiply 7 by 4, you get 28. that is not right. if this explanation is too confusing, i added a picture

Answer:

The measure, in degrees, of ∠ABC = 25°

Hence, option A is true.

Step-by-step explanation:

Given

The exterior angle m∠CBD = 155°

To determine

The measure of ∠ABC

We know that the exterior angle and interior angle are supplementary angles.

In other words, adding the interior angle and an exterior angle would give us 180°.

Here:

m∠CBD = 155° is exterior angle

∠ABC is the interior angle.

When we add m∠CBD and m∠ABC we would get 180°.

m∠CBD + ∠ABC = 180°

substituting m∠CBD = 155°

155° + ∠ABC = 180°

∠ABC = 180° - 155°

∠ABC = 25°

Therefore, the measure, in degrees, of ∠ABC = 25°

Hence, option A is true.

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.

Mr. Gorelick has gone crazy. He has climbed up to the rafters of the gym 35 feet up and has taken with him a large number of basketballs. Mr. Gorelick can throw a basketball so hard at an angle of declination of 40 degrees that it will knock you out for 17 hours. How far does one of his basketballs travel before hitting someone in the head?​

Answers

Answer:

Let the amount of feet be x

Let declination be y

so 35x at a declionation of 40 degrees 35x+40y=feet traveled before hitting the head

35x

40y

35x +40y= 40-y =35x+40-y

and 35x=35-x

35+40=x-y

The ball travels 43ft

Answers

your equation should be

160 +5x = 400
-160 -160

divide both sides by 5
5x/5 = 340/5
x = 68

so they need to sell 68 tickets at the door.

4(40) + 5(68) = 400
160 + 340 + 400

hypotenuse = ?

Now,

By the formula of Pythagoras Theorem,

h^2 = p^2 + b^2

h^2 = 30^2+16^2

h^2 = 900+256

h = sqrt ( 1156 )

h = 34

A carpenter has a wooden stick that is 84 centimeters long. She cuts off 25% from the end of
the stick. Then she cuts the remaining stick into 6 equal pieces. What is the length of each
piece?

How did you get 63?

Answers

Answer:   10.5 cm

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

Explanation:

25% = 25/100 = 0.25

25% of 84 = 0.25*84 = 21

So 21 cm has been cut off, leaving 84-21 = 63 cm left over

Or you could say that if 25% has been cut off, then 75% of the stick remains

So, 75% of 84 = 0.75*84 = 63 cm remains.

The remaining length of 63 cm is cut into 6 equal pieces

Each smaller piece is 63/6 = 10.5 cm long

Solve for the slope, x- and y-intercepts given the equation below.

7x + 2y = -10

x-intercept:

y-intercept:

Slope:

Answers

X intercept: (-10/7, 0)
Y intercept: (0, -5)
Slope: -7/2
First, you should put it into y-intercept form:
7x+2y=-10
2y=-10-7x
Y=(-7x-10)/2

The slope is the coefficient of x right now, so the slope is -7/2.

The x-intercept’s y is always 0, so we plug that into the equation as y=0.
7x+2y=-10
7x+2(0)=-10
7x+0=-10
X=-10/7

Therefore, the x-intercept is (-10/7,0).

Now, you do the same thing for the y-intercept where x=0 to find your y-intercept.
