steve and elsie are camping in the desert, but have decided to part ways. steve heads north, at 8 am, and walks steadily at 2 miles per hour. elsie sleeps in, and starts walking west at 2.5 miles per hour starting at 11 am.
After 2.57 hours, the distance between Steve and Elsie will be 25 miles.
What exactly is the distance?Distance is the sum of an object's movements, regardless of direction. The distance can be defined as the amount of space an object has covered, regardless of its starting or ending point. Use the formula d = st, or distance equals speed times time, to find the distance. Since both represent a certain amount of distance per unit of time, such as miles per hour or kilometers per hour, rate and speed are comparable.So, let t (hours) represent the amount of time Elsie needs to travel before they are 25 miles apart.
Steve takes longer because he is 2 hours earlier, so his time is t + 2.
Steve travels x[tex]s_s=2(t+2)[/tex] miles to the north.Elsie travels a distance [tex]s_c=2.5 t[/tex] to the west.So, according to the formula the distance between Steve and Elsie will be:
[tex]\sqrt{s_s^2+s_c^2}=\sqrt{(2(t+2))^2+(2.5 t)^2}=25[/tex]Solve for t as follows:
[tex]\begin{aligned}&(2(t+2))^2+(2.5 t)^2=25^2=625 \\&4(t+2)^2+6.25 t^2=625 \\&4\left(t^2+4 t+4\right)+6.25 t^2=625 \\&10.25 t^2+16 t-609=0 \\&t=\frac{-b \pm \sqrt{t^2-4 a x}}{2 a} \\&t=\frac{-16 \pm \sqrt{(16)^2-4 *(10.25) *(-109)}}{2 *(10.25)} \\&t=\frac{-16 \pm 68.74}{20.5}\end{aligned}[/tex]
So, t = 2.57 or t = -4.13.
As we know that time can only be positive so it t = 2.57.Therefore, after 2.57 hours, the distance between Steve and Elsie will be 25 miles.

A local pizza shop has a membership program for frequent buyers. The membership costs $25 per month and members get a discounted price of $1.25 per slice of pizza. Justin purchased a membership to this pizza shop. How much would Justin have to pay the pizza shop if he bought 12 slices of pizza this month? What would be the monthly cost for x slices of pizza?
PLEASE HURRY!
The amount that Justin would have to pay the pizza shop if he bought 12 slices of pizza this month is $15.
The monthly cost for x slices of pizza is $25 + $1.5x
What is the total cost?In order to determine the amount that Justin would have to pay the pizza shop if he bought 12 slices of pizza can be determined by multiplying the cost per pizza by the number of pizzas sold.
Multiplication is the operation used in mathematics that is used to calculate the product of two or more numbers. The sign that is used to represent multiplication is x.
Cost of 12 slices of pizza = discounted price x number of slices bought
$1.25 x 12 = $15
The monthly cost is the sum of the membership fee and the total cost of the pizzas bought
Monthly cost = monthly membership fee + cost of the slices
Monthly cost = monthly membership fee + (discounted price x number of slices bought)
$25 + (1.25 x x)

Using properties of exponents, the simplified expression for 5³ x 5^(-5) is given by:
A. 1/(5²).
How do we multiply two terms with the same base and different exponents?The exponent property applied to multiply the terms with the same base but different exponents is that we keep the bases and then add the exponents.
For this problem, the expression is given as follows:
5³ x 5^(-5)
Hence:
The base is of 5.The exponents are of 3 and -5.Adding the exponents, we have that:
3 + (- 5) = 3 - 5 = -2.
Hence the simplified expression is:
5³ x 5^(-5) = 5^(-2).
When a number has a negative exponent, we can move it to the denominator, then the exponent becomes positive, hence:
5^(-2) = (1/5)² = 1/5² = 1/25.
Meaning that option A is correct.

There are 15 year 12 pupils in a football club, out of a total of 46 pupils. write this proportion as a percentage. give your answer correct to 1 decimal place when appropriate.
In the football club, the percentage of 15-year 12 pupils out of 46 pupils is equal to 30%.
The proportion can be found by dividing the number of 15-year pupils by the total number of pupils. Therefore;
number of 15-year pupils / total number of pupils = 12 / 46 = 0.260
Rounding it to one decimal;
0.260 = 0.3
Percentage in mathematics can be defined as a number or a rate in each hundred. A decimal value can be converted into a percentage by multiplying the decimal value by 100.
0.3 × 100 = 30%
Therefore, the proportion of the 15-year pupils in the football club is 12/46 and this proportion can be written in percentage as 30%.

The midpoint is equal to one-half of the sum of the two points' x-coordinates and half of a sum of the two points' y-coordinates.For the given question;
The end point of the line segment is (0,0).
The mid-point of the line segment is at (4,-6).
Thus,
(x₁, y₁) = (0,0)
(x₂, y₂) = ?
(xₐ, yₐ) = (4,-6)
Thus, the formula for finding the mid point is;
xₐ = (x₁ + x₂)/2
Put the values;
4 = (0 + x₂)/2
