What are equivalent ratios?

"Two or more ratios that reflect the same relation or comparison of numbers are known as equivalent ratios," according to the definition of the equivalent ratio in mathematics. The idea of corresponding fractions is comparable. The term "proportion" also refers to the equivalence of two ratios. Even if the values of the antecedent and the consequent are different, if we simplify them, we will still arrive at the same value.

How to solve?

Mia's height=1.65 m

Tree's equivalent height=26.45m

Mia's height w.r.t. the tree's shadow=26.45-21.40 =5.05m

Ratio of the equivalent height w.r.t original height=5.05:1.65 =3.06

Tree's original height= tree's equivalent height: ratio of Mia's height

                                   = 26.45:3.06 =8.64m

A rectangular yard measuring 35 ft by 55 ft is bordered (and surrounded) by a fence. Inside, a walk that is 3 ft wide goes all the way along the fence. Find the area of this walk. Be sure to include the correct unit in your answer.

Answers

The area of walk is 504 square feet

Area of rectangle

The area of rectangle is define as a  product of length L and width w

calculate the area of rectangle yard

Area = L x W,  

where A equal the Area, L equals the length and W equal width.

A = 35 x 55

A= 1925 square feet

Area of the rectangular yard is 1925 square feet

From the question, we have 3ft wide goes all the way along the fence inside.

Therefore, we subtract six feet from each of the value of length ( 35) and width (55) because each side has 3feet .

Area = L x W

A = 29 x 49

A = 1421 square feet

Area of new rectangle formed by allowing for three foot walk is 1421 square feet

Area of Walk

To get the area walk;  we subtract area of new rectangular formed from area of rectangular yard

Area of Walk = Area of Rectangular yard - Area of new rectangle

Area of Walk = 1925 - 1421

Area of Walk = 504 square feet.

The linear equations that represent the relationships in the question order are;

y = 4·x - 1y = -x + 4[tex]y = \frac{1}{4} \cdot x -1[/tex][tex]y = -x + \frac{1}{4}[/tex]

What is a linear equation?

A linear equation is an equation of the form; y = m·x + c

The slope of the line is found as follows;

(-5 - (-21))/(-1 - (-5)) = 4

The equation is y - (-5) = 4·(x - (-1)) = 4·x + 4

y = 4·x + 4 - 5 = 4·x - 1

y = 4·x - 1

The y-intercept is (0, 4), the x-intercept is (4, 0)

The slope is therefore; (0 - 4)/(4 - 0) = -1

The equation is therefore; y - 0 = -1 × (x - 4) = -x + 4

y = -x + 4

The y-intercept is (0, -1), the x-intercept is (4, 0)

The slope is therefore; (0 - (-1))/(4 - 0) = 1/4

The equation is therefore; y - 0 = (1/4) × (x - 4) = x/4 - 4/4 =

y = x/4 - 1

The slope of the line is; [tex]\dfrac{-3\frac{3}{4} - \left(-\frac{3}{4}\right) }{4-1} = -1[/tex]

y - (-3/4) = -1 × (x - 1) = -x + 1

Answers

Answer: One Real Solution

We can Identify the coefficients a, b, and c from your equation because as it says, it is in the format of the quadratic equation ( ax^2 + bx + c = 0 )

a=2,b=-4,c=2

Now we can use the discriminant to determine how many solutions this has using the equation b^2 - 4ac

Once we plug in our coefficients:

(-4)^2 - 4 x 2 x 2

Once we simplify, we get 0.

One real solution.

I hope this helps.

In this case, we first need to simplify the given quadratic equation 2x² - 4x = -2, and to do so, we perform the following simplification steps:

For a quadratic equation of the form ax² + bx + c = 0, the discriminant is calculated using the following formula:

   Δ = b² - 4ac

In this case, we have that the equation that we must solve is 2x²-4=-2, which implies that the corresponding coefficients are:

a = 2b = -4c = 2

By introducing these values into the formula we get:

         Δ = b² - 4ac = (-4)² - 4·(2)·(2) = 0

Therefore, the discriminant for the given quadratic equation is Δ=0=0, which is zero, and indicates that the equation 2x²-4=-2 has only one real root.

We can say: It has a Real solution.

Cindy is attempting to calculate how much her car payment would be for a car that costs $27,000 to be repaid with monthly payments in 4 years at 4% APR.

Answers

Cindy's monthly payment of $609.63 will cost her $29,262.24 in 4 years at a 4% APR.

How is the total cost determined?

The total cost that Cindy will spend on the car which costs $27,000 is computed by multiplying the monthly payment by 48 months (the payment period).

The monthly payment can be determined using an online finance calculator that compounds the interest rate monthly for four years.

Cost of car = $27,000

Annual Percentage Rate (APR) = 4%

Payment period = 4 years (monthly)

N (# of periods) = 48 months (4 years x 12)

I/Y (Interest per year) = 4%

PV (Present Value) = $27,000

FV (Future Value) = $0

Results:

PMT = $609.63

Sum of all periodic payments = $29,262.24

Total Interest = $2,262.45

Thus, Cindy will spend $29,262.24 for a car that costs $27,000, if she repays monthly for 4 years.

How many children attended?
How many adults attended?

Answers

Answer is 2000 child tickets and 1700 adult tickets for a total of 3700 tickets sold

Step by step

a = adult tickets
c = child tickets

adult tickets = 3700 - child tickets
a = 3700 - c (equation 1)

$1.50 child tickets + $5 adult tickets = $11500
1.50c + 5a = 11500 (equation 2)

Now we have two equations.
Substitute equation 1 for “a” in equation 2 to solve for “c”

1.50c + 5(3700 - c) = 11500
Distribute

1.50c + 18500 -5c = 11500
Combine

-3.5c + 18500 = 11500
Subtract 18500 from both sides to isolate c

-3.5c + 18500 - 18500 = 11500 - 18500

-3.5c = -7000
Divide both sides by -3.5 to solve c

-3.5/-3.5 c = -7000/-3.5

C = 2000 child tickets sold

We know adult tickets = 3700 - child tickets

equation a = 3700 - c

Substitute our c value of 2000 into equation

a = 3700 - 2000

a = 1700 adult tickets sold

What are the coordinates of B′ after the pentagon is rotated 90° about the origin?

Assuming that the rotation is anticlockwise (as it is not defined) the coordinates of B after the rotation are (-5, 1), so the correct option is C.

What are the coordinates of B' after the rotation?

If the pentagon is rotated 90°, then all the vertices are also rotated 90° about the origin.

Here we don't know if the rotation is clockwise or anticlockwise, so we assume it is anticlockwise, as this is the standard rotation.

The orignal coordiates of point B are (1, 5)

This is on the first quadrant, a rotation of 90° anticlockwise will:

Interchange the x-value and the y-value.Add a negative sign to the new x-value.

So we will go from a point (x, y) to (-y, x)

Then the new coordinates of B' are (-5, 1)

Thus, the correct option is C.

Answers

The time it would take the rocket to hit the ground upon launch is; 3 seconds.

At what time does the rocket hit the ground?

It follows from the task content that the time taken for the rocket in discuss to hit the ground upon launch is to be determined.

Since the given formula for the height in terms of time, t is;

h = - 3t² + 3t + 18

It follows that ; when the rocket hits the ground; the height; h = 0.

Therefore;

0 = - 3t² + 3t + 18

0 = -3t² + 9t - 6t + 18

0 = -3t ( t - 3 ) - 6 ( t - 3)

-3t - 6 = 0 OR. t - 3 = 0.

t = -2. OR. t = 3.

Therefore, since the time after launch can only be positive; the time taken for the rocket to hit the ground is; 3 seconds.

How to find the equation of the line?

For a linear equation with a slope m and a known point (h, k), the slope-point form is written as:

y = m*(x - h) + k

Where y and x are the two variables.

Here we know that the slope is 1/2, and the known point is (1, -2), then the values on the equation above are:

Addends in math can be defined as the numbers that we add together to get a sum. The numbers you use in addition are called addends; in multiplication, the analogous term is a factor. If you add 7 to 112, the 7 is an addend, and the second number is an augend, though you're unlikely to hear anyone other than a math teacher use either of these phrases. Addere, which means "to add to, join, or attach," is the Latin root of the word addend.

Any number that is added to another is referred to as an addend in mathematics. When you add 10 to 15, 10 is the addend. An addend can alternatively be referred to as a summand.

At what radial distance from the center of a toroid of 300 windings does the magnitude of the magnetic field equal that found inside a solenoid that has 400 turns per meter of length? Assume that the current is the same through both devices.The magnitude of the magnetic field inside a toroid of total Ntturns and carrying a current I is, Bt=0NtI2s, where s is the distance of the field point from the center of the toroid. The magnitude of the magnetic field inside a solenoid of Ns turns per unit length and carrying a current I is Bs=0NI. So if for a value of s, the magnetic field inside a toroid and a solenoid are the same, then the value of s can be found by using the equation, 0NtI2s=0NsI. wendy is in school learning to be a welder. she spends long hours studying (and drinking coffee) and long hours practicing in the hot, dirty shop (and therefore takes frequent showers). wendy has $70.00 per month to spend on the soap and coffee she needs to function properly. in the accompanying graph, move the bc line to correctly depict wendy's budget constraint, assuming the soap costs $3.50 per bottle, and the coffee costs $14.00 per pound. if a point will not go where you want to put it, try placing the other endpoint there. If an element has an atomic number of 15 then (a) the atomic mass must also be 15 (b) the atom has 15 electrons (c) there are 7 electrons in the outermost shell (d) the atom has 15 neutrons (e) the atom must have only one orbital a. after spending hours researching his choices, mark decides on a laptop that will cost him $799. as he walks into his local retailer, a salesman presents him a laptop with marginally better features at the same price. however, mark would have to do further research to verify that the new alternative is in fact better. as a result, he decides that the laptop he previously decided on is good enough and buys it. Marks decision is an example ofa. bounded rationalityb. fairnessc. risk aversion examine a culture of rotifers, drawing what you see. label the corona, and describe its movement. add a tiny amount of the red-celled alga rhodomonas. can you observe the capture of cells by the corona?
