9 4/10= 94/10, 9.4..
Answer 2

Answer:

the answer is 9.4

Step-by-step explanation:

9 4/10= 9+1/10

we know that 4/10 is the same as 4÷10.

therefor:

9 4/10=9+(4÷10)

then using long division for 4 divided by 10 we have:

=9+0.4=9.4

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 ;)

Answers

Answer:

30 problems

Step-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 = 30

They were able to solve 30 problems before the new mathletes joined

Answer:

Answers

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?

Answers

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.

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

Answers

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].
