Answer:
-2t + 1400
Step-by-step explanation:
If t represents the number of hours Lamar worked as a tutor, the number of hours he worked as a waiter can be represented by 100 - t.
Create an equation to represent the situation:
12t + 14(100 - t) = total earned
Simplify:
12t + 1400 - 14t = total earned
-2t + 1400 = total earned
So, the expression for the amount he earned is -2t + 1400

Hope it helped youThe selling price of a refrigerator, is $638.00. If the markup is 10% of the dealer's cost, what is the dealer's cost of the refrigerator?
25% markup = original + 25% = 125% of original = 1.25 x original
Selling price = 1.25 x dealer price
Answer = 521.25/1.25=$417
The dealers price would be 100% they sell it for 10% more so it is sold at 110 % of what the dealer pays.
Divide the selling price by 110% to get the dealers cost.
638 / 110% = 638 / 1.1 = 580
The dealers cost is $580

The table shows the estimated number of deer living in a forest over a five-year period. Are the data best represented by a linear, exponential, or quadratic model? Write an equation to model the data.
Year
Estimated Population
0 91
1 70
2 54
3 42
4 32
A. quadratic; 0.77x2 + 91
B. exponential; y= 91 * 0.77x
C. linear; y= 0.77x + 91
D. quadratic; y= 91x2 + 0.77
Answer:
All I can say is that it isn't linear, as the number would then be the same every year
Answer:
B. exponential; y= 91 * 0.77x
Step-by-step explanation:
The Answer is A.
y=91*0.77^x
I just substituted the x on all of them and only one got the corrct y which is A.

i really need to find out how to find a,b, and c in the quadratic formula can u please help ASAP will mark as BRAINLIEST!!
Answer:
Brainliest, please! (Answer below)
Step-by-step explanation:
The basic form for any quadratic function is:
ax^2 + bx + c.
The constant of the 1st term, the x^2 constant, is a, the constant of the second term, the x constant, is b, and the constant, the third term, is c. There are some instances where there will not be a b or c. For example, x^2 + 2, or 3x^2 - 4x. However, there must always be an a, or else the function isn't quadratic.

Find the height of the triangle by applying formulas for the area of a triangle and
your knowledge about triangles.
A. 5.8 mm
B. 2.0 mm
OC. 4.4 mm
D. 6.2 mm
Answer:
Step-by-step explanation:
a= 12 mm ; b = 16 mm ; c = 18 mm
s = (a + b+c)/2
[tex]=\dfrac{12 + 16 + 8}{2}\\\\= \dfrac{36}{2}\\\\= 18\\\\[/tex]
s -a = 18 - 12 = 6 mm
s -b = 18 - 16 = 2 mm
s -c = 18 - 8 = 10 mm
[tex]area = \sqrt{s(s -a)(s-b)(s-c)}[/tex]
[tex]= \sqrt{18*6*2*10}\\\\= \sqrt{2160 }\\\\=46.47\\\\=46 \ mm^{2}\\[/tex]
[tex]\dfrac{1}{2}* \ base * \ height = 46\\\\\dfrac{1}{2}*16* \ height = 46\\\\height = \dfrac{46*2}{16}\\\\[/tex]
= 5.75
Height = 5.8 mm
Answer:
A. 5.8mm
Step-by-step explanation:
[tex]area \: of \: triangle = \sqrt{s(s - a) \times (s - b) \times (s - c)} \\ s = \frac{a + b + c}{2} \\ s = \frac{12 + 8 + 16}{2} \\ s = 18 \\ area \: of \: triangle \: = \sqrt{18(18 - 12) \times (18 - 8) \times (18 - 16)} \\ = \sqrt{2160} \\ = 46.47 {m}^{2} \\ area \: of \: triangle \: = \frac{1}{2} \times base \times height \\ 46.47 = \frac{1}{2} \times 16 \times h \\ h = \frac{46.47}{8} \\ h = 5.8mm[/tex]
I need help mhm yeah need help I can’t stop cussing ( not so much tho ) so my mum got mad at me and she keeps comparing me to my cousin and saying that she’s way better than me *sigh* it just gives me no self-esteem and brings me down, makes me thinking that I’m not worth it and everything else i don’t know what to do anymore any advice? ( sorry if this is not educati)
Answer:
just a random Teenage who's been through the same thing
Step-by-step explanation:
if you really care about what your mom think I'd suggest changing some thing's about you . maybe study more or something . if you don't usually try then go ahead try harder.
but if youre doing everything right but your cousin just seem to be better then you can't do much but try to explain to her that you're trying your best
stay safe and don't do anything you'd regret
Your question is not educational, but I'll be happy to give you some advice.
From a person who has dealt with a parent comparing me to others, I completely understand how you feel. Parents do sometimes get mad at their children for misbehaving but it not acceptable whatsoever to bring them down like that. I hope you understand that no one but YOU is allowed to dictate your worth. If you can, I suggest bringing this matter up with your mother and tell her how her remarks make you feel. If you cannot do that, I suggest speaking with a school counselor, friend, relative, or teacher about this. Sometimes expressing your feelings with others is the best medicine.
Have a great day!

Carson buys eggs and lemons at the store.
He pays a total of $39.62.
He pays $6.74 for the eggs.
He buys 8 bags of lemons that each cost the same amount.
Which equation could be used to determine xx, how much each bag of lemons costs?
Answer:
8x = 39.62 - 6.74
Step-by-step explanation:
Cost of 1 bag of lemons = $ x
Cost of 8 bags of lemons = 8 *x = 8x
Cost of 8 bags of lemons = Total cost - cost of the eggs
8x = 39.62 - 6.74
Answer:
3.
Step-by-step explanation:
[tex]x + y = 39.62 \\ x = 6.74 \\ y = \frac{39.62 - 6.74}{8} [/tex]

which best describes the meaning of the word theorem
A. A conjecture based on inductive reasoning
B. A statement that is accepted as true without proof
C. a statement explaining the meaning of a geometric term
D. A conclusion proved by deductive reasoning
Answer:
Step-by-step explanation:
It's D.
A theorem is true by some sort of mathematical logic.
It is not a definition. Not C
It is not in the end true because of inductive reasoning (a theorem may lend itself to inductive reasoning, but it must be proved.) Not A
It certainly not assumed to be true without proof. Not B

What is the measure of B?
Select the best answer from the choices provided.
A.33°
B. 57
C. 770
D.123
Answer:
B =57
Step-by-step explanation:
The sum of the angles of a triangle is 180
A+B+C = 180
58+B+65 = 180
123+B = 180
B = 180-123
B =57
The angle sum property of a triangle:
The total measure of the three angles of a triangle is 180°∠A + ∠B + ∠C = 180°
∠A = 58° ∠B = 65° ∠C = x⇛58° + 65° + x = 180°
⇛123° + x = 180°
⇛x = 180° - 123°
⇛x = 57°
Option B is the correct answer

The length of a rectangle is 9 inches more than the width. The perimeter is 34 inches. Find the length
Answer:
length = 13 inches
Step-by-step explanation:
let the length be x
hence, the width = x-9
perimeter = 2(x+x-9) = 34
2(2x-9) = 34
4x- 18 = 34
4x = 52
x = 13
