Step-by-step explanation:
If r is directly proportional to s and r 8 when s 3 find s when r 11
Answer:
s = 33/8 or 4 1/8
Step-by-step explanation:
find 'k', constant of proportionality first:
8 = 3k
k = 8/3
11 = 8/3s
s = 11/1 ÷ 8/3
s = 11/1 x 3/8
s = 33/8 or 4 1/8

Answer:
1. 6.13
2. 0.57
Step-by-step explanation:
1. 7 x 4 = 28
28 / 8 = 3.5
3.5 x 7 = 24.5 / 4 = 6.13
s = 6.13
2. 2 x 3 = 6
6 / 7 = 0.85
0.85 x 2 = 1.71
1.71 / 3 = 0.57
s = 0.57
Sorry if I get most of them wrong

The formula can be used to work outthe cost, in riyals, of hiring a helmet inQatar for a number of days.Kasun wants to hire a bicycle and a helmetfor the same number of days .
Answer:
The answer is below
Step-by-step explanation:
a) Cost of hiring the bicycle for 14 days is:
Cost = 65 * 14 days + 44 = 954 riyals
b) The number of days the bicycle is hired is to be the same as the number of days the bicycle is to be hired. Let us assume that the bicycle and helmet is to be hired for x days, hence:
Cost of bicycle = 65 * x + 14 = 65x + 44
Cost of helmet = 12.5 * x = 12.5x
Total cost = 65x + 44 + 12.5x = 77.5x + 44
Since 750 riyals is available, hence:
750 = 77.5x + 44
77.5x = 706
x = 9.11
Therefore the maximum number of days is 11. The total cost for 11 days is:
Total cost = 77.5(9) + 44 = 741.5 riyals
Money not spent = 750 riyals - 741.5 riyals = 8.5 riyals

In a science experiment, a student concluded that a ray has to travel a distance from one corner at the top of the rectangular prism to the opposite side where the surface touching the floor is intersected. If the length, width, and height of the prism are given as 24 inches and 8 inches, 6 inches respectively, what is the distance travelled by the ray?
Answer:10
Step-by-step explanation:24-6-8=10
The distance travelled by the ray will be 26 inches. Then the correct option is B.
What is coordinate geometry?Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

Then the distance travelled by the ray will be
We know the formula
D² = L² + W² + H²
We have
L = 24 in
W = 6 in
H = 8 in
Then the distance will be
D² = 24² + 6² + 8²
D² = 576 + 36 + 64
D² = 676
D = 26 in
Thus, the correct option is B.

An object’s will remain constant throughout the universe, but its can change from planet to planet. If you increase the mass of a planet, what happens to its gravity? If the gravity on a planet decreases, what happens to the weight of an object on that planet?
Answer:
Step-by-step explanation:
it becomes lighter :P or maybe you could say "bouncier" :P
Answer:
It decreaases
Step-by-step explanation:
If the gravity of a planet decreases, there is less pull to the center of said planet, making the object weigh less.

Answer:
c = 3477 feet (As rounded to the nearest whole number)
Step-by-step explanation:
We will use the Sin ratio for this problem since the opposite side of the Angle 15 is given and we have to find the triangle's hypotenuse;
Sin(15) = [tex]\frac{900}{c}[/tex]
=> Now isolate the variable c all to itself;
Sin(15) * c = 900
c = [tex]\frac{900}{Sin(15)}[/tex]
c = 3477.33 or 3477 feet

Solve the equation for all values of x in simplest form:
(x + 1)^2 = 25
Answer:
x =4, x = -6
Step-by-step explanation:
1. Square root the whole equation on both sides
2. You get x+1 = ±5 as the answer.
3. Simplify that to get x = 4 and x = -6.
4. This equation is a quadratic equation, so you should get 2 answers.
Answer:
x=6,−4
Step-by-step explanation:
1.Take the square root of each side of the equation to set up the solution for x
2.Remove the perfect root factor x−1 under the radical to solve for x.
3. Simplify the right side of the equation.
4. The complete solution is the result of both the positive and negative portions of the solution.
5. You get your answer!

Place the regions in order according to their population densities from least to greatest.
Answer: Region C ⇒ Region A ⇒ Region B
Step-by-step explanation:
Density = Number of people / Area of region
The regions are in circles based on the fact we were given the radius and area of circle = π * radius²
Region A Density = 14,200,000 / (3.142 * 13²)
= 26,742 people per square mile
Region B Density = 19,700,000 / (3.142 * 15²)
= 27,866 people per square mile
Region C Density = 23,550,000 / (3.142 * 18²)
= 23,133 people per square mile
Order from least to greatest is:
Region C ⇒ Region A ⇒ Region B
