Tristan and Evan are employees for a company. Tristan is making a salary of $49,000. Evan is earning a salary that is 29% lower than the salary of Tristan. What salary is Evan earning?
Answers
evan=$34790
you can do this two ways:
Find what is 29% of 49,000:
29/100 x 49,000 = 14,210
Then, minus it from 49,000:
49,000-14,210=34790
Evan earns $34790
The second way to do this is by using a multiplier:
First, minus 29 from 100:
100-29=71
Then, convert it to a multiplier by dividing by 100:
71/100=.71
.71 is now your multiplier, multiply this with 49,000:
49,000x.71=34790
You get the same answer as the first method

******HINT: If you have anything you can use to SHOW why it worked, try that. I recommend M&M's or a candy that has color. I suggest showing your number, and whats done to it in one color... 10 and what happens to that in another.*******
Think of a number 1-10
Double it
Add 10 to that number
Divide it by 2
Subtract your original number
Your answer is 5

Answer:
10 divided by 2 equals 5 and your original number added then subtracted would be 0, so 0 + 5 equals 5

Question:Determine if the two triangles are congruent. If they are, state how you know.
Answers
Answer: If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
Step-by-step explanation: So we know that two triangles are congruent if all of their sides are the same-- so side, side, side. We also know they are congruent if we have a side and then an angle between the sides and then another side that is congruent-- so side, angle, side.

1# Jason is participating in a walkathon. He writes the equation m = 2d + 50 to represent the amount of money he collects from each sponsor for walking d kilometers. What number represents the rate of change?
2# Cierra is keeping track of the amount of money in her lunch account each week. She writes the equation A = -6w + 40. What number represents the rate of change?
Answers
Answer:
The rate of change is the slope
In this case
m=2d+50 is a slope intercept equation.
where m is where the y would be
the 2 which is originally where the slope or (m) would be
the d for the (x)
and 50 for the y intercpet or (b)
so
#1=2
The expalantion is the same but different numbers, when asked for the rate of change look at the slope or the number next to the variable. Also put it in y=mx+b form to make sure the number is correct.
#2= -6
Mark often buys lunch at the deli next to his work. Lunch at the deli costs $7.50. Mark sets aside $150 for lunches at the deli at the beginning of the month. Which equation describes how much money, y, Mark has after eating lunch at the deli x times during the month?
Answers
Answer:
y = 150 - 7.50x
Step-by-step explanation:
Given that:
Cost per lunch = 7.50
Amoint budgeted for lunch = $150
The equation which models the amount of money, y Mark has after eating x times at the Deli
Amount left = Amount budgeted for lunch - (cost per lunch * number of lunch eaten)
y = $150 - ($7.50 * x)
y = 150 - 7.50x
f(3) = 3x² +b For the function, f, defined above, f(4) = 49. What is the value of b?
Answers
Answer: 5.4~
Step-by-step explanation:
For the problem F(3) = 3x^2 +b, you have to first figure out what F(3) is and in this case it is 49, so now you have part of the question solved. Then you start working on the other side of the equation 3x^2 +b = 49, we don't know what x is so lets figure it out, by that you need to do 3x^2, the equals 9. So, so far we have the equation 49 = 9x +b. Now we need to get rid of the x on the 9, having a variable is considered multiplying so you need to divide 9 by 9, but remember what you do to one side you have to do to the other, so now you have to divide 49 by 9 and you get 5.444444444. Now the equation is b=5.4~ meaning that b is around 5.4, I hope this helps.

Answer:
(c) f(x) = -3x^2 +x
Step-by-step explanation:
Points either side of (0, 0) have lower y-values, so you know the parabola opens downward. This eliminates the first two choices.
Trying one of the other points in the one of the remaining equations tells you which equation works.
For example, usint (-1, -4) in the third choice, we get ...
f(-1) = -3(-1)^2 +(-1) = -3 -1 = -4 . . . . . matches point (-1, -4)
The correct function is the third choice:
f(x) = -3x^2 +x
