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]
Simplify
[tex]6h\ge \:54[/tex]
Divide both sides by 6
[tex]\frac{6h}{6}\ge \frac{54}{6}[/tex]
Simplify
[tex]h\ge \:9[/tex]
Therefore,
[tex]6h+26\ge \:80\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:h\ge \:9\:\\ \:\mathrm{Interval\:Notation:}&\:[9,\:\infty \:)\end{bmatrix}[/tex]

does 3/7 , 12/21 make a proportion
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
The length of a rectangle is 15 more than 3 times the width. The perimeter is 110. What is the area
Answer:
450 units squared
Step-by-step explanation:
2(length)+2(width)=Perimeter
W=x Length=15+3w Perimeter=110
2(15+3w)+2w=110
30+6w+2w=110
8w=80
w=10
So: Length is 45 and Width is 10
Area is l*w
Area=45*10
Area is 450 units squared

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.
Will the solution (4, 6) satisfy the following equation: x + y = 18?
Five years ago you deposited a sum of money into a savings account which has earned $150 in interest. The interest rate for the account is 3% simple interest per year. How much money was originally deposited in the account?
Answer:
$1000
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year,
then, solving our equation
I = 1000 × 0.03 × 5 = 150
I = $ 150.00
The simple interest accumulated
on a principal of $ 1,000.00
at a rate of 3% per year
for 5 years is $ 150.00.

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?
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

Step-by-step explanation:
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.
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.

what is the solution of √5x+1-√x=5
Answer: x= 16
Step-by-step explanation:
Solve for x
√(5x + 1) − √x = 5
Add √x to both sides of the equation.
√(5x + 1)^2 = 5( + √x )^2
To remove the radical on the left side of the equation, square both sides of the equation.
√5x + 12 = (5 + √x)^2
Simplify each side of the equation.
5x + 1 = 25 + 10√x + x
Solve for 10√x.
10√x = 4x − 24
To remove the radical on the left side of the equation, square both sides of the equation.
(10√x)^2 = (4x − 24)^2
Simplify each side of the equation.
100x = 16x^2 − 192x + 576
Solve for x.
x = 9/4 , 16
Exclude the solutions that do not make √5x + 1 − √x = 5 true.x = 16
