Answer:
a) x + 8 ≥ 6
Step-by-step explanation:
x + 8 ≥ 6
Step 1: Subtract 8 from both sides
x + 8 - 8 ≥ 6 - 8
Step 2: Simplify
x ≥ -2
And since the symbol is greater than, we use a closed circle. Also, since the inequality is like an arrow pointing to the right, we draw the arrow going to the right.
Here are what the inequality symbols mean:
> = Greater than
≥ = Greater than or equal to
< = Less than
≤ = Less than or equal to
Open circles are used for numbers that are less than or greater than (< or >). Closed circles are used for numbers that are less than or equal to and greater than or equal to (≤ or ≥).

Answers
Answer:
30 gram doses
Step-by-step explanation:
First, turn the fractions into decimals.
1/4 gram to .25 gram
7 1/2 gram to 7.5 gram
Then, divide 7.5 total grams by the .25 grams for each dose.
7.5/.25 = 30
Therefore, you can obtain 30 1/4 gram doses from a 7 1/2 gram vial of medication.
Given:
Weight of the vial = [tex]7\frac{1}{2}[/tex] grams
Weight of one dose = [tex]\frac{1}{4}[/tex] gram
To Find:
Number of doses in one vial.
Solution:
Let the number of doses in a vial = n
Therefore, weight of 'n' doses = [tex]n\times \frac{1}{4}[/tex]
= [tex]\frac{n}{4}[/tex] grams
Since, the weight of the n doses is equal to the weight of one vial,
[tex]\frac{n}{4}=7\frac{1}{2}[/tex]
[tex]\frac{n}{4}=\frac{15}{2}[/tex]
[tex]n=\frac{15\times 4}{2}[/tex]
[tex]n=30[/tex] doses
Therefore, 30 doses can be obtained from one vial of medication.

A supplementary angle is an angle that forms 180°. To put into simpler words, it's the angle that makes a straight line.
A complementary angle is an angle that makes a 90° angle or a right angle.
An acute angle is an angle that is less than 90°.
An obtuse angle is an angle that is between 90 & 180 degrees.
A reflex is one that makes a 270° angle.
And finally you have a full/complete angle which makes a 360° angle
Finding the original price given the sale price and percent...
At a sale this week, a sofa is being sold for $234. This is a 28% discount from the original price.
What is the original price
Answers
Answer:
$325
Step-by-step explanation
78% is 234
x is 100%
cross multiply
[tex]\frac{234}{72}[/tex] = [tex]\frac{x}{100}[/tex]
234 × 100 = 72x
23400 = 72x
23400÷72 =72x ÷72
325 = x
The value of the original price of the sofa would be $325.
Used the concept of percentage that is,
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating the hundredth part of any quantity is called a percentage.
Given that,
At a sale this week, a sofa is being sold for $234.
And, This is a 28% discount from the original price.
Let us assume that the original price = x
Hence, the given condition is written as,
[tex]x - (28\% \ \text{of } x) = 234[/tex]
Solve for x,
[tex]x - (0.28 x) = 234[/tex]
[tex]0.72x = 234\\[/tex]
Divide both sides by 0.72,
[tex]x = \dfrac{234}{0.72}[/tex]
Therefore, the original price would be,
[tex]x = \$325[/tex]

Step-by-step explanation:
Answer:
using the simple interest rate Formula, I = prt.
given 3,000 as the principle,
6% as the rate, and 9 years as the time
I = (3000)(6%)(9)
I = (27000)(6%)
I = (27000)(0.06)
I = 1620$
Present value = I + p
present value = 1620$ + 3000$

Answer:
n = .3168
Step-by-step explanation:
Multiply .44 by .72.
You can use a calculator to do this or do it by hand.
If you choose to do it by hand, multiply using long multiplication without paying mind to the decimals, and then when you are finished, add the decimal four places to the left (at the very beginning of the number you should get). So, 3168 becomes .3168, or your final answer.

What is the radius of the circle in the xy-plane that
has center (1,5) and contains the point (4,9)?
Answers
[tex] \huge \qquad \sf \underline{\boxed{ {☘ \sf Sσlutiσn}}}[/tex]
The distance between the centre and any point satisfying the circle is its radius ~
Hence, the distance between the points is equal to length of radius.
[tex]\qquad \sf \dashrightarrow \: r = \sqrt{(4 - 1) {}^{2} + (9 - 5) {}^{2} } [/tex]
[tex]\qquad \sf \dashrightarrow \: r = \sqrt{(3) {}^{2} + (4) {}^{2} } [/tex]
[tex]\qquad \sf \dashrightarrow \: r = \sqrt{9 + 16} [/tex]
[tex]\qquad \sf \dashrightarrow \: r = \sqrt{25} [/tex]
[tex]\qquad \sf \dashrightarrow \: r = 5[/tex]
As we know, equation of a circle is :
[tex] \qquad \sf(x - h) {}^{2} + (y - k) {}^{2} = {r}^{2} [/tex]
where,
h = x - coordinate of centre k = y - coordinate of centre r = radius of the circleHence, equation of our required clrcle is :
[tex] \qquad \sf(x -1 ) {}^{2} + (y - 5) {}^{2} = {5}^{2} [/tex]
The radius of the circle that has center (1,5) and contains the point (4,9) is 5 units
How to determine the radius of the circle?The center of the circle is given as:
Center (a,b) = (1,5)
The point on the circle is given as:
Point (x,y) = (4,9)
The radius is calculated using the following distance equation
[tex]r = \sqrt{(x - a)^2 + (y - b)^2}[/tex]
So, we have:
[tex]r = \sqrt{(4 - 1)^2 + (9 - 5)^2}[/tex]
Evaluate the exponents
[tex]r = \sqrt{25}[/tex]
Take the square root of 5
r = 5
Hence, the radius of the circle is 5 units

plsss answerre huhu helppp
Answers
Answer:
L = (6u + 5)m ; W = (2u-3)m
Step-by-step explanation:
Given;
Area of the rectangular vegetable garden, A = (12u² - 8u - 15)m²
Let the length of the rectangular vegetable garden = L
Let the width of the rectangular vegetable garden = W
A = L x W
Factorize the given area;
= 12u² - 8u - 15
= 12u² -18u + 10u - 15
= 6u(2u - 3) + 5(2u - 3)
= (6u + 5)(2u-3)
Thus, L = (6u + 5)m and W = (2u-3)m
Option B, is the right solution, although it was wrongly typed.
