The American Heart Association recommends that you consume less
than 1500 milligrams of sodium per day. Today you have already taken
in 400 milligrams of sodium. Write and solve an inequality that represents
the additional amount of sodium you can consume.
The inequality that represents the additional amount of sodium you can consume is x< 1100, where x is the additional consumption.
What is an inequality and how to solve it ?An inequality is a statement that compares two expressions we can solve an inequality by adding same number to both sides or by subtracting same number from both side. While adding or subtracting the sign of the inequality will not change .
Given that American Heart Association recommends that you consume less than 1500 milligrams of sodium per day
∴ total consumption per day < 1500 milligram
400 milligrams of sodium is already taken today and let x be the additional amount that can be consumed today
Total consumption today will be 400+ x milligrams
∴ (400+x) < 1500
Subtracting 400 from both sides
⇒ x<1500-400 = 1100
Therefore, the additional amount of sodium that can be consumed today must be less than 1100 milligrams today.

A salesperson makes 18% commission on every TV sold. If the salesperson sold four TV’s at $885 each, how much commission did they make?
Answer:
They made a $531 commission.
Step-by-step explanation:
The given is:
The price of each TV is $885The commission is 18% on every TV soldThe salesperson sold 4 TV'sWe need the value of the commission
Let us find the commission of every TV, then find the total amount of all
∵ The price of each TV is $885
∵ The commission is 18 %
→ Find 18% of $885
∴ The commission on every TV = 885 × 15%
∴ The commission on every TV = 885 × 15/100
∴ The commission on every TV = $132.75
∵ The salesperson sold 4 TV
∴ The commission on them = 4 × 132.75
∴ The commission on them = $531
They made a $531 commission.
Answer: $637.20
Step-by-step explanation:
Each TV is $885
do 885 · 18% or 885 · 18/100
that is 159.3
multiply that by the amount of TVs sold (4)
159.3 · 4 = 637.2
$637.20

Which of the polygons below makes the following statement false?
All ________ have at least one line of symmetry.
rectangles
trapezoids
rhombi
squares
Answer:
trapezoids.
Step-by-step explanation:
rectangles will always have symmetry because they have 90-degree angles and can't be irregular. squares are rectangles so they also have symmetry. Rhombi by definition have two pairs of identical angles, so they must be symmetrical.
Trapezoids have angled sides, which don't have to be the same, therefore, trapezoids makes the statement false

Zander is comparing the height and weight of his friends and family members. He'd like to create a data display to see if there is a relationship between his friends' height and weight. Below is the scatter plot he designed.
A scatter plot labeled Height and Weight is shown. The x-axis is labeled Height (in inches) and has tick marks ranging from 0 to 80, separated by increments of 10. The y-axis is labeled Weight (in pounds) and has tick marks ranging from 0 to 250, sepa
Explain, using complete sentences, whether or not this is the most appropriate format for representing this data and why. If it is not the best format, explain which format should have been used instead. (5 points)
Answer:
I believe it is a good representation because it shows the differences in the heights to the weights.
Answer:
No, I don't believe this is the most appropriate format, the scatter plot is good but the weight section is not labeled correctly, the dollar signs don't belong, they are irrelevant to weight and height. And the height section should be changed to feet instead of inches, it would just make more sense.

Write the equation of the parabola in vertex form.
vertex (4,4), point (3, -1)
Answer:
[tex]y=-5(x-4)^2+4[/tex]
Step-by-step explanation:
Equation of the Quadratic Function
The vertex form of the quadratic function has the following equation:
[tex]y=a(x-h)^2+k[/tex]
Where (h, k) is the vertex of the parabola, and a is a coefficient different from zero.
The vertex is located at (4,4).
Substituting the coordinates of the vertex, the equation of the function is:
[tex]y=a(x-4)^2+4[/tex]
The value of a will be determined by using the given point (3,-1).
[tex]-1=a(3-4)^2+4[/tex]
Operating:
[tex]-1=a(1)+4[/tex]
Solving:
[tex]a=-5[/tex]
The equation of the graph is:
[tex]\boxed{y=-5(x-4)^2+4}[/tex]

Round 345,047 to the nearest thousand ten thousand hundred thousand
345,000 ; 350,00 ; 300,000.
Answer:
300,000
Step-by-step explanation:
the ten hundred thousands place would be
100,000
therefore the nearest ten hundred thousand would be
300,000
because the 345,047 isn't a high enough digit to be 5+ and make the nearest thousand 400,000 and not 300,000
If that doesn't help, think of it like this...
Anything before the place is what determines if the number will be higher or lower.
45 is lower than 50 and 50+ is the passing number to make the number 400,000.
Tip: when your rounding numbers the only numbers that stay the same and don't turn into 0's is like the 3 in "345,047" but the "45,047" part turns into 0's is because those aren't needed and because you rounded it, it's like it takes those numbers to make what you rounded to higher or lower.
so if you look at it like that the answer is 300,000.

compounded semi animally to have $50,000 in the account after 6 years?*
Answer:
$33,090.
Step-by-step explanation:
The formula is A = P( 1 + r/2)^2n so we have:
50,000 = P(1 + 0.07/2)^(6*2)
50000 = P * 1.035^12
P = 50000/ 1.035^12
= $33,090 to the nearest dollar.

if (a, -12) is a point on the graph of y=x^2-7x, what is a?
If so, you can insert that y = -12 and solve for a which will equate to x.
[tex]-12=x^2-7x[/tex]
[tex]x^2-7x+12=0[/tex]
[tex](x-3)(x-4)=0\implies a_1=3,a_2=4[/tex]
So a could be 3 or 4 (has two solutions).
Hope this helps.
How might you prove your observations from question 4 about the length of a midsegment using geometric theorems? Briefly outline an approach using what you know about midpoints, parallel lines, and congruent triangles. Use the figure you created in GeoGebra to guide you.
Answer:
To prove the relationship about the length of a midsegment, I can use the properties of parallel lines and transversals. If I draw at least two midsegments, I see that they form congruent triangles within the original triangle, ∆ABC. I can prove the congruence of these triangles using triangle congruence criterion, and then use properties of congruent triangles and the Transitive Property to show that the length of the midsegment is half the length of the side it is parallel to.
