The 30 members of a choir are trying to raise at least $1,500 to cover travel costs to a singing camp. They have already raised
Darya [45]

Answer:

B

Step-by-step explanation:

30 is the amount of members and each have to raise at least the goal but they have already raised $600. For them to reach this goal the amount they get does not have to be more than the goal since it's at least and they need to raise the goal. So they need to raise at least $1500 which leads us to answer B 30x+600>=1500 (in word terms thirty x plus six hundred is greater than or equal to fifteen hundred). Hope this helps and I got threw this a little while back sucks at first but you'll get it with time easier.

Answer:

If your asking us to just combine like terms it would be -3b^2-2b^2+1.4b+4c+c

but if your asking us to answer the question it would be -5b^2+1.4b+5c

Hope I helped :)

Which is the equation of Line B?
notka56 [123]
  • Slope-Intercept Form: y = mx + b, with m = slope and b = y-intercept
  • Slope Formula: \frac{y_2-y_1}{x_2-x_1}

So firstly, to find the slope of this equation, plug the two points, (1,1) and (-3,2), into the slope formula and solve as such:

\frac{1-2}{1-(-3)}=-\frac{1}{4}

Next, plug either one of the points into the x and y coordinates to solve for b as such:

2=-\frac{1}{4}*-3+b\\2=\frac{3}{4}+b\\\frac{5}{4}=b

<u>Our final equation is y=-\frac{1}{4}x+\frac{5}{4} , or the third option.</u>

If the cost is $138.25 and the desired markup is 12.5%, then what is the price after markup?
KIM [24]
First, you must turn the 12.5% into a decimal, which would then become .125. You then multiply that by the $138.25 and you would get 17.28. Then you just add the $138.25 to the $17.28 where you would then get $155.53 as your answer. Please let me know if I am wrong.

Takashi ran 200 yards in 40 seconds Ana ran 150 yards in 25 seconds can u tell who runs faster without rewriting the rates expla
Marina86 [1]
150 is smaller than 200 so 25 is smaller than 40, but 25, in perspective to the numbers, is much smaller than 40. Ana is faster.

Check:

Takashi: 200 divided by 400 equals 5 yd/sec
Ana: 150 divided by 25 equals 6 yd/sec
