Answer:

$5820.07

Step-by-step explanation:

Substitute 243 into the equation for n:

[tex]c=117\sqrt[3]{243^{2} }+1264\\c=117\sqrt[3]{59049}+1264\\c=117*38.9407384+1264\\c=4556.06639+1264\\c=5820.06639[/tex]

Answer:

11 students  :)

Step-by-step explanation:

That should be correct if I'm wrong just ignore this.

The number of students who took more than 45 minutes to complete their homework is 11.

A stem-and-leaf display, also known as a stem-and-leaf plot, is a technique used to visualize the shape of distribution by displaying quantitative data in a graphical fashion, similar to a histogram.

For the given stemplot the number of students who took more than 45 minutes to complete their homework can be calculated by counting the number of observations that are more than 45.

Therefore, the observations that are more than 45 are 48, 49, 51, 53, 53, 53, 53, 55, 60, 60, and 60.

Hence, the number of students who took more than 45 minutes to complete their homework is 11.

Answer:

40 kilometers

Step-by-step explanation:

the hypotenuse is a² + b² = c²

so first we have to get 32 and 24 into ²

            32² = 1024       (32 × 32)

            24² = 576         (24 × 24)

1024 + 576 = 1600

now we need to find the square root of 1600

√1600 = 40     (calculator)

therefore, the hypotenuse is 40 kilometers

Step-by-step explanation:

10x^2=50x

10x=50

x=5

Answer: x=0.1

Step-by-step explanation:

Given

The function is given by [tex]F(x)=x^2-0.2x+0.01[/tex]

A standard quadratic equation is given by [tex]ax^2+bx+c=0[/tex]

The given equation has an exponent of x as 2 which confirms it is a quadratic equation. Compare it with the standard equation

[tex]a=1,b=0.2,c=0.01[/tex]

Therefore, the given equation is the quadratic equation.

Its solution is given by

[tex]\Rightarrow x=\dfrac{0.2\pm \sqrt{(-0.2)^2-4\times 1\times 0.01}}{2\times 1}\\\\\Rightarrow x=0.1[/tex]

Answer:

[tex]\boxed {\boxed {\sf D. \ x=20}}[/tex]

Step-by-step explanation:

If line m and line r are parallel, the two angles must be congruent, because they are alternate interior angles. Notice how the 2 lines and the transversal form a backwards "Z" and the angles are in the inner corners.

So, if the angles are congruent, we can set them equal to each other.

[tex]7x-115=3x-35[/tex]  

Now, solve for x by isolating the variable. First, move all the constants to one side and the terms with variables to another.

115 is being subtracted and the inverse of subtraction is addition. Add 115 to both sides.

[tex]7x-115+115=3x-35+115\\7x= 3x+(-35+115) \\7x=3x+80[/tex]

3x is being added and the inverse of addition is subtraction. Subtract 3x from both sides.

[tex]7x-3x=3x-3x+80 \\4x=80[/tex]

x is being multiplied by 4. The inverse of multiplication is division. Divide both sides by 4.

[tex]4x/4=80/4\\x=20[/tex]

If the lines are parallel, then x=20 so the angles are congruent.

Answer:

11

Step-by-step explanation:

H =V/(LxW)/3

H = 297/(9x9)/3

H = 297/(81)/3

H = 297/27

H = 11

Therefore, the height of the pyramid is 11ft square

Answer:

the median is 5 the mode is 5 and 2 the mean is 6.25 and the range is 15

Step-by-step explanation:

the mode is 5 and 2 because they both occur the most often

The median is 5 because even though the amount of numbers is even and there is no exact middle the two middle numbers are both 5 and 5+5 equals 10 divided by 2 equals 5

the mean is 6.25 because all numbers added together 75 divided by the amount of numbers 12 equals 6.25

the range is 15 because the range is the diff between the highest and lowest value

Answer:

39.19 yards^2

25.15 yards

Step-by-step explanation:

To determine the squares square yards of carpet needed, we have to determine the area of the room

The room is shaped like a rectangle

area of a rectangle = length x breadth

5.7 x 6 7/8

To multiply, convert 6 7/8 to a  decimal

to do this, divide 7 by 8. Add the value gotten to 6

5.7 x 6.875 =39.19 yards^2

To determine the yards needed for the border, calculate the perimeter of the room

Perimeter = 2 x (length + breadth)

2 x(5.7 + 6.875) = 25.15 yards

Answer:

Explanation:

since this triangle is a right-angled triangle and one its angles equals 45° then it's an isosceles right triangle which means that the side opposite 45° (the side to the left) is equal to 13 too.

so according to pythagoras theorem c = √(a²+b²)

x =√(13²+13²)

x = √(169+169)

x = √338

x ≈ 18.38

note: in the question it's mentioned to find y! and I believe it is just an error! it's about to find x and that's more resonable!

Answer:

$250

Step-by-step explanation:

Given:  Cost for d days carnival = $2d^3 .....(i)

where d is number of days

Now we have to calculate the total cost incured for 5 days of carnival

we can simply put d = 5 in above equation (i)

= 2×5^3 = 2×125 = $250.

Therefore carnival cost if Eduardo goes for d 5 days = $250
