Marcus jogged [tex]2\frac{1}{2}[/tex] miles over the weekend.
Marcus jogged [tex]1\frac{2}{5}[/tex] miles on Saturday and 9/10 miles on Sunday.
we first need to find a common denominator:
[tex]1\frac{2}{5}[/tex] = 7/5
9/10 = 0.9 miles
Now, we can round each of these to the nearest 1/2:
7/5 is closer to [tex]1\frac{1}{2}[/tex] than 1, so we round to [tex]1\frac{1}{2}[/tex]
0.9 is closer to 1 than 1/2, so we round to 1
Adding these rounded values, we get:

Select all the correct answers. What are the solutions to this equation? 2 x 2 = - 10 x + 12 x = - 6 x = - 2 x = 1 x = - 3 x = 6
Answer:
The correct solutions to the equation 2x^2 = -10x + 12 are x = -2 and x = 3.
Step-by-step explanation:
An entrepreneur invests in a new play. The cost includes an overhead of $33,750 plus production costs of $1700 per performance. A sold-out performance brings in $2325 . Assume every performance is sold out, and let x represent the number of sold-out performances.
The entrepreneur's revenue is $2325x, entrepreneur's cost is $33,750 + $1700x and entrepreneur's profit from x sold-out performances is $625x - $33,750
The entrepreneur's revenue from x sold-out performances is given by the formula:
Revenue = (Price per Performance) x (Number of Performances)
Revenue = $2325 x x
Revenue = $2325x
The entrepreneur's cost from x sold-out performances is given by the formula:
Cost = Overhead + (Production Cost per Performance) x (Number of Performances)
Cost = $33,750 + $1700x
The entrepreneur's profit from x sold-out performances is the revenue minus the cost:
Profit = Revenue - Cost
Profit = $2325x - ($33,750 + $1700x)
Profit = $625x - $33,750

Mrs.lealas living room has an area of 144 square feet.
Her dining room is ⅓ the area of the living room and ⅖ the area of the kitchen. What is the area, in square feet, of the kitchen?
The Area of Kitchen is 120 square feet.
We have,
Area of living room = 144 square feet
So, the dining room
= 1/3 (area of living room)
= 1/3 (144)
= 48 square feet
and, Area of Dining room = 2/5 x Area of kitchen
48 = 2/5 x Area of kitchen

Every winter, the math club sells cookie dough to raise money. Last year, they sold 1,080 pounds of cookie dough to 360 people. This year, they predict that they will sell cookie dough to between 460 and 500 people. About how many pounds of cookie dough will they need?
A.
2,880
B.
1,440
C.
720
D.
2,160
The number of pounds of cookie dough needed is 1,440. Therefore, option B is the correct answer.
Given that,
Last year, they sold 1,080 pounds of cookie dough to 360 people.
This means that they sold an average of 3 pounds of cookie dough per person.
Number of pounds of cookie dough = 3 pounds/person × Number of people
Here, 3×460=1,380
3×500=1500
To get a more accurate estimate, we can take the average of these two numbers, which is 1,440 pounds of cookie dough.

If you can buy one bunch of seedless green grapes for $2, then how many can you buy with $18?
If you can buy 1 bunch of seedless green grapes for $2, then $18 we can buy 9 bunches.
The concept used here is a simple division to find out how many bunches of seedless green grapes can be purchased with a given amount of money.
In this case, we know the cost of one bunch of seedless green-grapes ($2) and we are given a total amount of money ($18) that we can spend on grapes. We can use division to find out how many bunches we can buy with that amount.
⇒ Number of bunches = ($18)/($2) per bunch,
⇒ Number of bunches = 9 bunches;

Select the correct answer below:
y=2/3x2
2y4(x2+y2)=3x2
2x4(x2+y2)=3y2
y=√3/2x
Answer: correct answer is A 2/3x^2
Step-by-step explanation:Multiply each side of the equation by 2cos2θ to get 2rcos2θ=3sinθ.
Multiply each side of the equation by r to get 2r2cos2θ=3rsinθ. Using the relationships x=rcosθ and y=rsinθ, the equation becomes 2x2=3y.
Divide each side of the equation by 3 and reverse the order of the equation to find that y=2/3x^2
[tex]x-\sqrt{x} +4-2\sqrt{x+3} =0\\[/tex]
The solution of the equation x - √x + 4 - 2√(x+3) =0 is given by x ≈ 0.449 or x = 2.
The expression is equal to,
x - √x + 4 - 2√(x+3) =0
By rearranging the terms and simplifying the expression as follows,
x - √x + 4 - 2√(x+3) = 0
⇒x + 4 = √x + 2√(x+3)
Square both sides to eliminate the square root,
⇒ (x + 4)² = (√x + 2√(x+3))²
⇒ x² + 8x + 16 = x + 4(x+3) + 4√x√x+3
⇒x² + 8x + 16 -x -4x -12 = 4√x√x+3
⇒ x² + 3x + 4 = 4√x√x+3
⇒x² + 3x + 4 = 4√x√(x+3)
⇒ x² + 3x + 4 = 4√(x²+3x)
Squaring both sides again gives,
⇒ (x² + 3x + 4)² = 16(x²+3x)
Expanding the left side gives,
x⁴ + 6x³ + 17x² + 24x + 16 = 16x² + 48x
Simplifying and rearranging the terms,
x⁴ + 6x³ + x² - 24x + 16 = 0
Factor this equation as follows,
(x² + 4x - 2)(x² + 2x - 8) = 0
The solutions are,
x²+ 4x - 2 = 0 or x² + 2x - 8 = 0
Solve each quadratic equation using the quadratic formula,
For x² + 4x - 2 = 0
x = (-4 ± √(4² - 4(1)(-2))) / (2(1))
⇒ x = (-4 ± √24) / 2
Simplifying the expression under the square root gives,
⇒ x = (-4 ± 2√6) / 2
⇒ x = -2 ± √6
For x² + 2x - 8 = 0
x = (-2 ± √(2² - 4(1)(-8))) / (2(1))
⇒x = (-2 ± √36) / 2
Simplifying the expression under the square root gives,
⇒ x = (-2 ± 6) / 2
⇒ x = -4 or x = 2
Discard the negative solution -2-√6 and -4
As it would lead to a negative value under the square root.
The final solutions are,
x ≈ 0.449 or x = 2
Therefore, the solution of the given equation is equal to x ≈ 0.449 or x = 2.

How many liters each of a 50% acid solution and a 60% acid solution must be used to produce 60 liters of a 55% acid solution? (Round to two decimal places if necessary.)
To produce 60 liters of a 55% acid solution, we need 18 liters of a 50% acid solution and 42 liters of a 60% acid solution.
Let x be the number of liters of the 50% acid solution needed, and y be the number of liters of the 60% acid solution needed.
We can set up two equations based on the amount of acid and the total volume:
0.50x + 0.60y = 0.55(60)
x + y = 60
Simplifying the first equation:
0.50x + 0.60y = 33
5x + 6y = 330 (multiplying both sides by 10)
We can solve for one variable in terms of the other in the second equation, and substitute into the first equation:
y = 60 - x
5x + 6(60 - x) = 330
Simplifying:
x = 18
So we need 18 liters of the 50% acid solution, and:
y = 60 - x = 42
So we need 42 liters of the 60% acid solution.

The formula given is incorrect.
The correct formula for Pythagorean triples with a given integer z is:
(z² - 1², 2z, z² + 1²)
Using this formula, we can find the two legs of the right triangle with hypotenuse 29 as follows:
z² + 1² = 29²
z² + 1 = 29²
z² = 29² - 1
z² = 840
z = √840
z = 28.98
Since z must be an integer, we can try integer values close to 28.98 to find one that works.
Trying z = 29,
a = z² - 1² = 840 - 1 = 839
b = 2z = 58

The biker needs to travel 45 km more to complete his journey.
Given that, a biker traveled 2/5 of the road on the first day, then traveled 5 kilometers less on the next day, which is equal to 3/8 of the road, we need to find how much he need to cover more,
Let the total distance of the road be x,
So,
2x/5 - 5 = 3x/8
2x/5 - 3x/8 = 5
Solving for x,
Multiply by 40 to both sides,
16x-15x = 200
x = 200
Therefore, the total distance of the road is 200 km.
Since, he travelled =
200 (2/5) = 80 km + 200 (3/8) = 75 km = 155 km
Therefore, he needs to travel 200-155 = 45 km more.
