Step-by-step explanation:
if x-3 is directly proportional to the square y and x=5 when y=2 find x when y=6
Answer:
If x-3 is directly proportional to the square of y, then we can say that:
(x-3) = ky^2
Where k is a constant of proportionality.
If x=5 when y=2, we can substitute these values into the equation to find the value of k:
(5-3) = k(2)^2
2 = 4k
k = 0.5
Now that we have the value of k, we can use it to find the value of x when y=6:
(x-3) = (0.5)(6)^2
x-3 = 18
x = 21
So, if x is directly proportional to the square of y and x=5 when y=2, then x=21 when y=6.

In the given right angled triangle ABC, right
angled at B. P is the mid-point of AC. Prove that
BP=1/2AC
The right angled triangle is missing, so i have attached it.
Answer:
Proved below
Step-by-step explanation:
From the attached image, we can see that QP is parallel to BC.
Now, looking at triangles AQP and ABC, we can see that;
∠ AQP = ∠ ABC
Also;
∠ APQ = ∠ ACB
This means that triangles ABC and AQP are similar.
We are told that P is the mid-point of AC.
Thus; AP = PC
We can now say that;
AP:AC = 1:2 and AQ:AB = 1:2
Since AQ:AB = 1:2, it means Q is the midpoint of AB.
Now, ∠ AQP = ∠ BQP
However, according to SAS congruence test, AQP is congruent to BQP.
Thus; AP = BP = CP
Since AP:AC = 1:2 as we saw earlier, then;
BP:AC = 1:2
Thus:
BP/AC = ½
BP = ½AC

The value of x is 12/5 from the equation 2x+[tex]4\frac{1}{5}[/tex]=9
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 2x+[tex]4\frac{1}{5}[/tex]=9
Two times of x plus four and one fifth equal to nine.
Convert the mixed fraction to improper
[tex]4\frac{1}{5}[/tex]=21/5
Now the equation will be 2x+21/5=9
Now subtract 21/5 from both sides by substitution property
2x=9-21/5
2x=45-21/5
2x=24/5
Divide both sides by two by division property.
x=24/10
x=12/5
Hence, the value of x is 12/5 from the equation 2x+[tex]4\frac{1}{5}[/tex]=9

Answer:
Lauren will finish the race faster 7 seconds faster, and 14 meters ahead.
Step-by-step explanation:
To answer this question, I will use the strategy of finding the slope of each of the proportional relationships (y = 8x for Lauren's run and y = ?x for Amani's run). The slope represents the rate at which the distance changes for each unit of time, so the person with the greater slope will finish the race faster.
To find the slope of Amani's run, I will use the tool of point-slope form, which is y - y1 = m(x - x1). I will plug in the coordinates for the second point listed in the table for Amani's run (5 seconds and 30 meters) to get y - 30 = m(5 - x1). Since I don't know the value of x1, I will solve for it in terms of m. I get x1 = 5 - (30/m).
Next, I will plug in the coordinates for the first point listed in the table for Amani's run (3 seconds and 18 meters) into the equation y - 30 = m(5 - (30/m)). I get 18 - 30 = m(5 - (30/m)). Solving for m, I find that Amani's run has a slope of m = -6.
Since Lauren's run has a slope of 8 and Amani's run has a slope of -6, Lauren will finish the race faster. To find out by how much, I will use the tool of proportional reasoning. Since the slope represents the rate at which the distance changes for each unit of time, the difference in the slopes (8 - (-6)) represents the difference in the rate at which the distance changes for each unit of time between the two runs. The difference is 14, so Lauren will finish the race 14 meters ahead of Amani for each second that they run. Since the race is 100 meters long, Lauren will finish the race approximately 7 seconds faster than Amani.

Answer:
[tex]CB = 7.5[/tex]
Step-by-step explanation:
Well, if the question gave you a right triangle, an angle, and the side length of the side opposite to that angle, this question should scream (TRIGONOMETRY). So tap into your brain and think about how you can use sin, cosine, and/or tangent to solve the problem.
So notice that the question is asking for the side length of CB, the side adjacent to the angle C (53 degrees). Since we already have the length of the side opposite to C (10), we can use tangent, because we know the value of tan58 if we put it in a calculator, and we know the length opposite to C.
[tex]tan(53) = 10/CB[/tex]
[tex]CB * tan(53) = 10[/tex]
[tex]CB = \frac{10}{tan(53)}[/tex]
[tex]CB = \frac{10}{1.327} = 7.5359...[/tex]

Dave can clean pools at a constant rate of 3/5 pools/hour. How long does it take Dave to clean 15 pools?
9 hours will it take to clean the 15 pools.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Dave can clean pools at a constant rate of 3/5 pools per hour.
This also means that he cleans 3 pools in 5 hours
So, the time taken to clean 15 pools is
= 15×3/5
= 9 hours.
Hence, the time taken is 9 hours.

Plzzz help I need a answer . farmer buys donkeys and horses for R53 800 . Altogether he buys 100 Animals . The price of the horse is R730 and of a donkey is R 230 . How many of each animal did he buy ?
Answer: horse = 61.6
donkey = 38.4
Step-by-step explanation:
Let number of donkey be d
Let number of horse be h
Based on the question given, we can form an equation which will be:
d + h = 100 ........ i
230d + 730h = 53800 ........ ii
Multiply equation i by 230
230d + 230h = 23000 ...... iii
230d + 730h = 53800 ....... iv
Subtract iii from iv
500h = 30800
h = 30800/500
h = 61.6
Since d + h = 100
d = 100 - 61.6 = 38.4

a cell phone company has a basic monthly plan of $40 plus $0.45 for any minutes used over 700. Before receiving his statement, John saw he was charged a total of $48.10. Write and solve an equation to determine how many minutes he must have used during the month. write an equation without decimals.
Answer: 718
Step-by-step explanation:
The formula for determining the cost of the cell phone bill (when more than the base number of minutes is used) is
c=p+(m−b)r
Where:
c is the total cost of the bill: $48.10 for this problem.
p is the base price of the plan: $40 for this problem.
m is the number of minutes used: what we are solving for this problem.
b is the base number of minutes allowed: 700 for this problem
r is the rate for additional minutes: 0.45 for this problem
Substituting and solving for m gives:
$48.10 = $40.00 + (m − 700)$0.45
$48.10 − -$40- = $40.00 − -$40- + (m − 700)$0.45 $8.10= 0 + (m−700)$0.45
$8.10 = (m - 700)$0.45
$8.10 = ($0.45 × m) − ($0.45 × 700)
$8.10 = $0.45m − $315.00
$8.10 + -$315.00- = $0.45m − $315.00 + -$315.00-
$323.10 = $0.45m − 0
$323.10 = $0.45m
[tex]\frac{323.10}{-0.45-}=\frac{0.45m}{-0.45-}[/tex] (Money)
[tex]\frac{323.10}{0.45}=\frac{0.45m}{0.45}[/tex] (Money): cross out the dollar sign for 323.10 and 0.45 under it... then cross out 0.45m but leave the m, and then cross out 0.45 under it.
[tex]\frac{323.10}{-0.45-}=m[/tex]
718 = m
m = 718
John used 718 total minutes during the month.

Describe trigonometry.Correlations between triangles' angles and sides are studied in the branch of mathematics known as trigonometry. Since every straight-sided form may be reduced to a collection of triangles, trigonometry can be found throughout geometry. The relationships between trigonometry and other branches of mathematics, in particular calculus, real or complex, infinite series, logarithms, and infinite series, are astonishingly complicated.
