After a few mathletes join the team, the team is able to solve 40% more problems per session. Of the team can solve 42 problems per session now, how many problem were they able to solve before the new mathletes joined? (Please EXPLAIN how you got it ;)
Answer:
30 problemsStep-by-step explanation:
Let the number of the problems the team could solve before is x.
Then we have:
x + 40% = 421.4x = 42x = 42/1.4x = 30They were able to solve 30 problems before the new mathletes joined
Answer:
[tex]\tt{}x = 30 \\ [/tex]
Step-by-step explanation:
[tex]\tt{}x + 40\% = 42[/tex]
[tex]\tt{}1.4x = 42[/tex]

Answer:
Not bad
Step-by-step explanation:
According to the internet, there are a number of factors to consider before estimating your waste percentage when buying carpets.
You may have to check the shape of your room, if it has multiple walls or if it is just complicated. For this kind you can estimate a 20% waste factor.
But for uncomplicated rooms having the same width as the carpet, the rule of thumb is to add a 10% waste factor to the square footage area.

find the area of the isocele triangle formed by the points of intersection of parabolas y=-x^2+9 and y=2x^2-3 and the origin
Answer:
[tex]10\ \text{sq. units}[/tex]
Step-by-step explanation:
The parabola's are
[tex]y=-x^2+9[/tex]
[tex]y=2x^2-3[/tex]
So
[tex]-x^2+9=2x^2-3\\\Rightarrow 12=3x^2\\\Rightarrow \\\Rightarrow x=\sqrt{\dfrac{12}{3}}\\\Rightarrow x=\pm 2[/tex]
[tex]y=-x^2+9=-(2)^2+9\\\Rightarrow y=5[/tex]
[tex]y=-(-2)^2+9=5[/tex]
So, the points at which the parabola's intersect each other is [tex](2,5)[/tex] and [tex](-2,5)[/tex]
The three points of the triangle are [tex](2,5)[/tex], [tex](-2,5)[/tex] and [tex](0,0)[/tex]
Area of a triangle is given by
[tex]A=\dfrac{1}{2}[x_1(y_2-y_3) + x_2(y_3-y_1) + x_3(y_1-y_2)]\\\Rightarrow A=\dfrac{1}{2}[2(5-0)+(-2)(0-5)+0(5-5)]\\\Rightarrow A=10\ \text{sq. units}[/tex]
Area of the triangle formed is [tex]10\ \text{sq. units}[/tex].
The high temperatures, in degrees Fahrenheit, of 10 U.S. Cities during a day in October are listed below. 72, 50, 54, 66, 58, 79, 54, 99, 40, 68 What is the range of the temperatures? A. 54°F B. 59°F C. 62°F D. 64°F
Answer: B. 59°F
Step-by-step explanation:
Range = Maximum - MInimum.
From the given temperatures, Maximum temperature = 99 degrees Fahrenheit
Minimum temperature = 40 degrees Fahrenheit
Range = Maximum temperature - Minimum temperature
i.e. Range =99-40 = 59 degrees Fahrenheit
Hence, the range of the temperatures = 59°F i.e. B is the correct option.

Train A and train B leave a central station at the same time. They travel the same speed, but in opposite directions, with train A heading towards station A, and train B heading towards station B. Train A reaches station A after 4 h. Train B reaches station B after 3 1/2 h. Station A and Station B are 562.5 mi apart.
What are the rates of the trains?
Answer:
since the rate is the same for both trains, and we know that the distance train A travels plus the distance train B travels equals 562.5 miles, we can use the D(istance) = R(ate) * T(ime) formula to solve this.
Train A:
da = R * 4
Train B:
db = R * 3.5 (using 3.5 instead of 3 and 1/2)
Solve for R:
R * 4 + R * 3.5 = 562.5
7.5 * R = 562.5
R = 75
The trains are traveling at 75 miles per hour.
Step-by-step explanation:
Answer:
speed = distance / time
since they are moving in opposite direction, the time is the sum of the two times = 2 1/2 + 4 = 6 1/2 = 13/2
speed = 585/(13/2) = 90 miles per hour.

HELLLLPPPPP, will make brainiest :)
Answer:
no
Step-by-step explanation:
the area of the whole box is 17,280 cubic units because 24x24x30=17,280. If each cubic unit is .004 lbs then multiply 17,280 by .004. And it equals 69.12 lbs. And 69 is bigger than 30, so no he cant lift it.
