The expression shows Aliya's rate in miles per hour will be 1/2.
How to compute the expression?From the information, Aliya hikes up a mountain for 2 hours and during this time, she hikes a distance of 1 miles.
Therefore, the rate will be:
= Distance / Time
= 1 / 2
Therefore, the expression shows Aliya's rate in miles per hour will be 1/2.

5r+5= 3(5r - 4) – 10r
Answer: No solution
Step-by-step explanation:
5r + 5 = 3(5r - 4) - 10r Do multiplication
5r + 5 = 15r - 12 - 10r combine like terms
5r + 5 = 5r - 12 This is impossible. 5r cannot equal 5 and 12 meaning there is no value of r that makes this equation true so there's No Solution.
You could continue
5r + 17 = 5r
-5r =-5r
17=0 which is also not true

What do we mean by random sample?A simple random sample (or SRS) in statistics is a subset of individuals (a sample) chosen at random from a larger set (a population) with the same probability.It is the process of selecting a sample at random. In SRS, each subset of k people has the same chance of being chosen for the sample as any other subset of k people.To find what number of children occurred the least frequently:
We know that a total of 1250 couples were polled.Determine the lowest frequency and divide it by the total number of couples surveyed.The lowest frequency corresponds to 5 or more children.The percentage is as follows:
50/1250 × 100 = 4.72Therefore, only (B) 4.72% of the couples polled have 5 or more children.

Mel makes arm bracelets . she is making one for each arm of her six friends . How
many should she make
Mel should make 12 bracelets.
Here, we are given that Mel makes arm bracelets.
She is making a bracelet for each arm of her 6 friends.
We know that a humans by default have 2 arms each.
We will assume that all of her 6 friends have 2 arms each.
Thus, 6 of her friends will get 2 bracelets each, one for each arm.
This means that the total number of bracelets Mel should make will be given by-
2 + 2 + 2 + 2 + 2 + 2
or we can also write this as
2 × 6
6 times 2 is equal to 12.

2. y varies directly as the square root of x, and y = 12, when x = 49. Find the value of y when x = 225. 3. R is inversely proportional to the cube of S and R = 8 when S = 3. Find the value of R when S=6. 4. n varies directly as the square root of t and inversely as l. If n = 5 when t = 16 and 1 = 2, find t when n = 10 and 1 = 3.
We need to use the concept of proprotionality for the given question.The value of y is 25.7, value of R is 1 and value of t is 144.
It is given that y varies directly as the square root of x which means that y is directly proportional to x, we can write it as
y∝[tex]\sqrt{x}[/tex] which can again be written as y=[tex]\sqrt{x} k[/tex] where k is a proportionality constant,we need to find the value of k inorder to find the value of y.We know that y=12 when x=49
12=[tex]\sqrt{49} k[/tex]=7k⇒12=7k⇒k=[tex]\frac{12}{7}[/tex]
when x=225 then y=[tex]\sqrt{225}[/tex]×[tex]\frac{12}{7}[/tex]=15×[tex]\frac{12}{7}[/tex]=25.7
R is inversely proportional to the cube of S,we can write it as
R∝[tex]\frac{1}{S^{3} }[/tex] ⇒R=[tex]\frac{k}{S^{3} }[/tex]
We need to find the value of k inorder to find the value of R, it is given that R=8 when S=3
8=[tex]\frac{k}{27}[/tex]
k=27x8=216
Value of R when S=6 will be
R=[tex]\frac{216}{6^{3} } =\frac{216}{216} =1[/tex]
It is given that n varies directly as the square root of t and inversely as l,we can write it as
n∝[tex]\frac{\sqrt{t} }{l}[/tex] which can be again written as n=[tex]\frac{\sqrt{t} }{l} k[/tex] where k is a proportionality constant,we need to find the value of k first to find the value of t
We know that n=5 when t=16 and l=2
5=[tex]\frac{\sqrt{16} }{2}k=\frac{4}{2} k=2k[/tex]
k=[tex]\frac{5}{2}[/tex]
We know that n=10,l=3 and k=[tex]\frac{5}{2}[/tex] substituting these values we can get the value of t
t=[tex](\frac{nl}{k} )^{2}[/tex]=[tex](\frac{10.3.2}{5} )^{2} =12^{2} =144[/tex]
Thus we can see that using the concept of proportionality we found out the values of y,R and t. Value of y is 25.7, R is 1 and t is 144.

Madelyn read 45 pages in 1 1/3 hours . At what rate , in pages per hour , did she read?
Madelyn reads at the rate of 33.75 pages per hour.
Here rate is defined as the number of pages read per hour. Rate or unit rate is defined as the quantity that is done in 1 unit of time(second, minute or hour). Distance per time is called speed. Velocity per time is called acceleration.
Here it is given Madelyn reads 45 pages in [tex]1\frac{1}{3}[/tex] hours.

Following are the steps to construct a line segment that is twice the given segment :
Step 1 : Take the compass and measure the length of the given line segment let’s say AB
Step 2 : Now with that measure put one end of the compass on one of the points of a line segment, either point A or point B.
Step 3 : Now mark an arc on the right side of the point if the compass is on point B or mark the arc on the left side if the compass is on point A.

Given,
3.The points are:
(-1,-2) and (1,-8)
let the points be :
(-1,-2) = (x₁,y₁)
and (1,-8) = (x₂,y₂)
The equation of the line passing through the points (-1,-2) and (1,-8)
x - x₁/x₂-x₁ = y - y₁/y₂-y₁
For the given points, the equation is:
x-(-1)/1-(-1) = y-(-2)/-8-(-2)
x+1/2 = y+2/-6
-6(x+1) = 2(y+2)
-6x-6=2y+4
-6x-2y-6-4=0
-6x-2y-10=0
-2(3x+y+5)=0
3x+y+5=0 is the equation of the line.
4.The points are:
(-3,6) and (3,0)
let the points be :
(-3,6) = (x₁,y₁)
and (3,0) = (x₂,y₂)
The equation of the line passing through the points (-1,-2) and (1,-8)
x - x₁/x₂-x₁ = y - y₁/y₂-y₁
For the given points, the equation is:
x-(-3)/3-(-3) = y-6/0-6
x+3/6 = y-6/-6
-6(x+3) = 2(y-6)
-6x-18=2y-12
