If a cube has the area of 144 m^2 on each face, then what would the surface area be?

Option D:

Right triangle

Solution:

Let us first define obtuse, acute right triangle and supplementary.

Obtuse angled triangle:

If any one of the angle in the triangle is more than 90°, then the triangle is an obtuse angled triangle.

Acute angled triangle:

If all the angles of the triangle are less than 90°, then the triangle is an acute angled triangle.

Right angled triangle:

If any one of the angle in the triangle is exactly 90°, then the triangle is a right angled triangle.

Supplementary:

If sum of the angles is 180°, then the angles are supplementary angles.

But this is not a kind of triangle.

In given triangle one of the angle is 90°.

Therefore, this is a kind of right triangle.

Option D is the correct answer.

Answer:

The expression for the width of the rectangle is [tex]9x^{5}y^{5}[/tex].

Step-by-step explanation:

The formula to compute the area of a rectangle is,

[tex]Area=length\times width[/tex]

Given:

Area = [tex]45x^{8}y^{9}\ square\ yards[/tex]

Length = [tex]5x^{3}y^{4}\ yards[/tex]

Determine the expression for the width of the rectangle as follows:

[tex]Area=length\times width\\45x^{8}y^{9}=(5x^{3}y^{4})\times width\\width = \frac{45x^{8}y^{9}}{5x^{3}y^{4}} \\=\frac{45}{5}\times [x^{8-3}]\times [y^{9-4}]\\ =9x^{5}y^{5}[/tex]

Thus, the width is [tex]9x^{5}y^{5}[/tex].

The numbers are 71 and 19

Solution:

Let "x" be the larger number

Let "y" be the smaller number

Given that,

Sum of two numbers is 90

Therefore,

x + y = 90 ------ eqn 1

The larger number 14 more than 3 times the smaller number

Larger number = 14 + 3(smaller number)

x = 14 + 3y ------ eqn 2

Let us solve eqn 1 and eqn 2

Substitute eqn 2 in eqn 1

14 + 3y + y = 90

14 + 4y = 90

4y = 90 - 14

4y = 76

Divide both sides by 4

y = 19

Substitute y = 19 in eqn 2

x = 14 + 3(19)

x = 14 + 57

x = 71

Thus the numbers are 71 and 19

Answer: The distance from the person on the ground to the bottom of the hotair balloon is 1,649 ft

Step-by-step explanation: Please refer to the attached diagram

From the diagram, the hotair balloon is labelled B. If Marero looks down and forms an angle of depression of 20°, that means he is forming an angle of 70° to point C where one of the two persons are standing. Point B is an angle of 70° (point A cuts point B at a perpendicular, that is, 90°)

With these we can now use the trigonometrical ratio of tangent to calculate the distance marked x on the diagram.

Tan B = opposite/adjacent

Tan 70 = x/600

When we cross multiply, we now have

Tan 70 × 600 = x

2.7475 × 600 = x

1648.5 = x

Rounded to the nearest feet

x = 1,649 feet

Final answer:

To determine the distance of the person from the ground point below the hot-air balloon, we use the angle of depression and the tangent trigonometric ratio. The calculation yields approximately 1648 feet when rounded to the nearest whole number.

Explanation:

To solve for the distance of the person at point C from the point on the ground directly below the hot-air balloon, we need to use trigonometric ratios. To find this distance, which we'll call 'd', we'll use the tangent of the angle of depression. The angle of elevation from the person looking up to the hot-air balloon would also be 20° because alternate interior angles created by a transversal intersecting two parallel lines are congruent. The relationship we use is:

tangent of angle = opposite/adjacent

In this case:

tan(20°) = 600/d

To isolate 'd', we take:

d = 600 / tan(20°)

Using a calculator, we find:

d ≈ 600 / 0.3640 ≈ 1648.35 feet

Rounded to the nearest whole number, the person at C is approximately 1648 feet from the point on the ground below the hot-air balloon.

step 1

Find the volume of a typical cereal box

[tex]V=LWH[/tex]

substitute the given values

[tex]V=(2.5)(7.75)(11.75)=227.65625\ in^3[/tex]

Convert to cubic feet

Remember that

[tex]1\ ft=12\ in[/tex]

so

[tex]1\ ft^3=1,728\ in^3[/tex]

so

[tex]227.65625\ in^3=(227.65625/1,728)\ ft^3[/tex]

step 2

Find the volume of all of the boxes of breakfast cereal bought in the united states in one year

Multiply the volume of one box by 2.7 billion boxes

[tex](227.65625/1,728)(2,700,000,000)=355,712,890.625\ ft^3[/tex]

step 3

If the warehouse is 10 feet tall what could the side lengths of the floor be?

Divide the volume by the height to obtain the area of the rectangular base

[tex]A=(355,712,890.625)/10=35,571,289\ ft^2[/tex]

If the floor were a square, the dimensions would be

5,964 ft by 5,694 ft approximate

The area of the warehouse's floor can be calculated by dividing the total volume of cereal boxes by the height of the warehouse, which is given to be 10 feet. The exact dimensions of the floor (length and width) cannot be determined from the information given. Many combinations of length and width can yield the same area.

Given the problem, it is implied we must estimate the size of the warehouse able to contain the volume of all the cereal boxes purchased in the United States in one year. The shape mentioned is a rectangular prism (a box), with known height 10 feet. The area of the warehouse floor (base) would be the total volume divided by the height of the warehouse.

However, the information needed to calculate the exact dimensions of the warehouse's base (length and width) is not provided in the question. Essentially, many combinations of length and width could yield the same area. For example, if the area was 200 sq ft, it could be 20 ft by 10 ft, or 40 ft by 5 ft, and so on.

To solve the equation -2/9m + 12 = -8 for m, subtract 12 from both sides, then multiply by -9/2. The solution is m = 90.

Explanation:

To solve the equation -2/9m + 12 = -8 for m, start by isolating the term involving m. Subtract 12 from both sides of the equation to get:

-2/9m = -8 - 12

-2/9m = -20

Next, multiply both sides by -9/2 to solve for m:

m = (-20) * (-9/2)

m = 180/2

m = 90

Therefore, the solution to the equation is m = 90.

Tyler gets $30 in change after buying a 7-day snowboarding ticket with a discount, having gone to the ticket counter with $340.

To calculate the change Tyler gets back, we must first determine the total cost of his 7-day snowboarding trip with the discount.

Tyler plans to snowboard for 7 days. A daily ticket costs $50. Since he is going to snowboard for 7 or more days, he gets a discount of $40 off the total.

Tyler goes to the ticket counter with $340. To find out how much change he gets back, we subtract the total cost from the amount he has:

$340 - $310 = $30

Therefore, Tyler will receive $30 in change.

Answer:

-6n-20=-2n+4(1-3n)

Solution

The bracket should be expanded

-6n-20=-2n+4-12n

Then we collect the like terms

-6n + 2n+12n = 20+4

8n=24

Now divide both sides by 8

8n/8 =24/8

n = 3

You can now insert 3 into anywhere you see n and see how it goes

-6n-20= -2n + 4(1-3n)

-6(3) - 20 = -2(3) + 4[ 1-3(3)]

-18 -20= -6 + 4(1-9)

To solve the equation, isolate and substitute variable 'y' in the first equation with 'x - 4'. This leads us to find 'x = 5'. Substituting 'x' in the first equation gives us 'y = 1'. Therefore the solution is 'x = 5, y = 1'.

The subject at hand is an algebra problem involving a system of two equations. First, we can select which variable to isolate. In our case, isolating 'y' in the first equation would be easier than it might seem. That would leave us with 'x = y + 4'.

Next, we can substitute 'y' with  'x - 4' in the second equation, giving us '3x + (x - 4) = 16'. We simplify this equation to '4x = 20'. Solving this gives us 'x = 5'. Lastly, we replace 'x' in the first equation with '5', which gives us the value of 'y = 5 - 4', so 'y = 1'.

The solution to the system of equations 'x = y + 4 and 3x + y = 16' therefore is 'x = 5, y = 1'.

To determine the house's value over time, a function can be created using the initial value and an annual growth rate. Specific details about the growth rate are needed for an accurate function, but a generic formula with a constant rate can still be provided.

Creating a Function for House Value Over Time

To write a function that determines the value of a house in thousands of dollars based on the number of years since purchase, we would need additional information about how the house's value appreciates or depreciates over time. This could involve a fixed annual appreciation rate, market trends, renovations, or depreciation.

Without specific data, a generic function can still be proposed, assuming a constant annual percentage increase. Let's call the annual growth rate 'r' (in decimal form) and the original value of the house 'V'. The function would then be:

f(t) = V × (1 + r)^t

For example, if Kyle bought the house at a value of $100,000 (or 100 in thousands of dollars) and the annual growth rate is 3% (or 0.03), the function defining the future value of the house would be:

f(t) = 100 × (1 + 0.03)^t

Using this formula, we can calculate the future value of Kyle's house after any number of years 't'.

Explanation:

(i) When the car has only 80 m to stop, show that [tex]3v^2+20v-1600<0.[/tex]

The distance, [tex]d[/tex] [tex]m[/tex], it takes for a car moving at a speed of [tex]v[/tex] [tex]m/s[/tex]  to stop completely is given by [tex]d=0.15v^2+v[/tex]

The car must stop before the 80 m, so the distance to stop is less than 80 m:

                       [tex]d<80[/tex]

                      [tex]0.15v^2+v<80[/tex]

             [tex]20\times 0.15v^2+20\times v<20\times 80\\\\3v^2+20v<1600[/tex]

            [tex]3v^2+20v-1600<0[/tex]

Which is the expression you wanted to prove.

(ii) Solve the inequality in part (i) to find the maximum speed of the car.​

To solve the inequality you need to factor the left side:

         [tex]3v^2+80v-60v-1600<0[/tex]

         [tex]3v^2-60v+80v-1600<0[/tex]

         [tex](3v^2-60v)+(80v-1600)<0[/tex]

        [tex]3v(v-20)+80(v-20)<0[/tex]

          [tex](v-20)(3v+80)<0[/tex]

There are two possible solutions: 1) the first factor is positive and the second negative, and 2) the first factor is negative and the second positive.

1. First tentative solution

              [tex]v-20>0\\\\v>20\\\\3v+80<0\\\\3v<-80\\\\ v<-80/3\\\\v<-26.26[/tex]

The speed cannot be greater than 20m/s and less than - 26.26 m/s at the same tine, thus, there are not solutions for this assumption.

2. Second tentative solution

              [tex]v-20<0\\\\v<20\\\\3v+80>0\\\\3v>-80\\\\ v>-80/3\\\\v>-26.26[/tex]

You are looking for an upper bound, thus the solution is that the speed is less than 20m/s.
