Answers
By using Percentage , Profit distributed to Charity A is £ 624 and Charity B is £ 336
What is Percentage ?A figure or ratio stated as a fraction of 100 is called a percentage. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a standard measurement.
The Latin phrase "per centum," which meaning "by the hundred," was the source of the English word "percentage." Fractions having a denominator of 100 are called percentages. In other words, it is a relationship where the value of the entire is always assumed to be 100.
Finding the percentage of a whole in terms of 100 is what percentage calculation refers to. A percentage can be found in one of two ways:
use the unitary approach.by adjusting the fraction's denominator to 100.It should be noted that when the denominator is not a factor of 100, the second technique of percentage calculation is not applied. In these situations, we employ the unitary technique.Total ticket sold = 800
Cost of each ticket is £ 2
Total fund raised (raw) = 2 * 800 = £1600
4% of the ticket won a prize of £20 each
so total number of tickets winning a prize = 4 % of 800 = 32
Total prize money distributed = 32 * 20 = £ 640
Total amount to distribute to charity = 1600 - 640 = £ 960
Total profit that goes to Charity A is = 65 % of 960 = £624
And rest to charity B is = £ 336

Given that is directly proportional to (p-1)2 and p is always positive, find the
value of p when q = 80 , if 9= 30 when p = 7
A) 4
B) 6
Ch 10.82
Answers
Answer:
p = 10.8
Step-by-step explanation:
Given that p is directly proportional to (p-1)² and p is always positive, then;
q = k (p-1)²
If q = 30 and p = 7
30 = k(7-1)²
30 = 6²k
30 = 36k
5 = 6k
k = 5/6
To get p when q = 80
q =k (p-1)²
80 = 5/6((p-1)²
480 = 5(p-1)²
480/5 = (p-1)²
(p-1)² = 96
p-1 = √96
p-1 = 9.8
p = 9.8 + 1

After a 5% tax,a DVD costs $21.How much did it cost before the 5% tax was added?
Answers
Answer:
$20
Step-by-step explanation:
You want to know the pre-tax price if the price with 5% tax added is $21.
TaxThe added tax is 5% of the original amount (x), so the amount with tax added is ...
$21 = x + 0.05x = 1.05x
$21/1.05 = x = $20 . . . . . divide by the coefficient of x
The cost before tax was added was $20.
Step-by-step explanation:
Percentage left after the tax percentage is
100%-5%=95%
95% is equal to 95/100 = 0.95
therefore, the cost after tax divided by the percentage that is left after the tax percentage
costs after tax is 21 dollars which is

You have to know that there are 6 square surfaces on a cube.
So the equation would be 6a² because is the surface area formula and is equal to 100 square inches
Solve for the a:

a = 4 in
A bucket contains 15 white, 8 pink, 3 yellow, and 10 blue golf balls. A golf ball is chosen at random, not replaced, then another is chosen at random. What is the probability of choosing a blue golf ball and then a pink golf ball?
Answers
To calculate the probability of a specific outcome, we will use the following principle
Probability of a specific outcome = total number of ways in which we get that outcome / total number of possible outcomes.
In this case, we can imagine at first that we are only choosing 1 ball. If we have a total number of balls of n, and we don't care the color of the ball, we could get any of the n balls. So the total number of outcomes for choosing one ball is n. In this case, n is the total number of balls. That is 15 (white) + 8(pink)+3(yellow) + 10(blue) = 36.
Now, note that choosing first 1 blue ball and then 1 pink ball, is the same as considering the case of just choosing 1 ball of a specific color.
For the first case, let us consider the outcome of picking 1 blue ball. At the first draw, we have 36 balls in total and we have 10 blue balls.
So, the probability of choosing 1 blue ball in the first try is 10/36.
Now, assuming we picked one ball that was blue, and we didn't put it back, now we have a total of 35 balls. In this scenario, the probability of picking a pink ball is 8/35 since we have 8 pink balls in a total of 35.
Now, to calculate the probability of having both outcomes is just the multiplication of this two numbers, that is
\(\frac{10}{36}\cdot\text{ }\frac{8}{35}\text{ = 0.0635}\)16 p = 208 p = Pls help quick
Answers
Answer:
p=0
Step-by-step explanation:
When you isolate both variables, one side becomes 0.
Answer:
p = 0
Step-by-step explanation:
16p=208p
Subtract 208p from both sides.
16p−208p=0
Combine 16p and −208p to get −192p.
−192p=0
Product of two numbers is equal to 0 if at least one of them is 0. Since −192 is not equal to 0, p must be equal to 0.

e) which line is steeper bruce or felicia? Whose slope is greater? Does this match the comparison from part c?
f) What does the greater unit rate, or slope, mean in terms of the solution? What can you conclude from this?
Answers
We can respond to that by addressing the problem at hand As a equation result, Felicia's equation has a slope of B and a y-intercept of 0, whereas Bruce's equation has a slope of A and a y-intercept of 0.
What is equation?A math equation is a procedure that connects two claims and uses the equals symbol (=) to denote equivalence. An equation in algebra is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, in the calculation 3x + 5 = 14, the equal sign places a space between the values 3x + 5 and 14. The relationship between the two sentences that are written on each side of a letter may be understood using a mathematical formula. The logo and the specifically software are frequently the same. as in, 2x - 4 Equals 2, for instance.
Let A represent the area that each tile covers. Following that, the area that Bruce covered, y, in terms of the quantity of tiles he employed, x, is given by:
y = Ax
Similarly, Felicia covered the space, y, by using the following number of tiles, x:
y = Bx
B is the area that each tile utilised by Felicia covers.
d) The equations are as follows when written in slope-intercept form:
For Bruce, y = Ax + 0.
For Felicia, y = Bx + 0.
As a result, Felicia's equation has a slope of B and a y-intercept of 0, whereas Bruce's equation has a slope of A and a y-intercept of 0.

Amy has three times as many Star Wars toys as Carly. Total they have 232 Star Wars toys. How many Star Wars toys does Amy have?
Answers
Answer:
174
Step-by-step explanation:
Since we don't know how many toys Carly has, we'll use a variable (x). The equation would then be:
x+3x=232
We can then combine like terms, and the new equation would be:
4x=232
Now, we have to get x by itself. To do this, divide both sides by 4, and you get:
x=58
But, remember, x is how many Carly has. Amy has three times that, so:
58*3=174
Amy has 174 toys.

Two trains leave Evas station 70 minutes apart. Train X leaves first at 1:15 pm and heads west at a speed of 106 km/h. Train Y leaves later and travels directly north at a speed of 128 km/h.
a) How far apart are these trains (along a hypotenuse) at 4:05 pm?
b) If Train Y has an unplanned stop that lasts 24 minutes, how far apart should these two trains be at 5:50 pm?
c) If both trains turn around and head back to Evas station, with Train X travelling at a new average speed of 142 km/h, which one will arrive first? Show your work and explain your thinking.
Answers
Train X is 374.39 km far apart from train Y (along the hypotenuse) at 4:05 pm and 627.009 km far apart (along the hypotenuse) at 5:50 pm.
Define hypotenuseIt goes without saying that the side opposite the right angle is the hypotenuse of a right triangle. This side of a right triangle is the longest.
given: Train X travels at a speed = 106 km/h
Train X started moving on 1:15
Train Y travels at a speed = 124 km/h
Train Y started moving on 2:25 pm
a) Time taken by train X = 2 h 15 min = 2.83 h
Speed = 106 km/h
Distance = speed * time
Distance = 106 * 2.83
Distance travelled by train X towards west is 299.98 km.
Time taken by train Y = 1 h 45 min = 1.75 h
Speed = 128 km
Distance = speed * time
Distance = 128 * 1.75
Distance travelled by train Y towards north is 224 km.
By using Pythagoras theorem,
(299.98)² + (224)² = hypotenuse²
89988 + 50176 = hypotenuse²
Hypotenuse = 140164 = 374.39
Therefore, distance between train X and train Y at 4:05 pm along hypotenuse is 374.39 km.
b) Time taken by train X = 1 h 45 min = 1.75 h
Speed = 106 km/h
Distance = speed * time
Distance = 106 * 1.75
Distance travelled by train X is 185.5 km.
Total distance travelled by X = 299.98 + 185.5 = 485.48 km
Time taken by train Y = 1 h 21 min = 1.35 h
Speed = 128 km
Distance = speed * time
Distance = 128 * 1.35
Distance travelled by train Y is 172.8 km
Total distance travelled by Y = 224 + 172.8 = 396.8 km
By using Pythagoras theorem,
(485.48)² + (396.8)² = hyopotenuse²
235690.84 + 157450.24 = hypotenuse²
393141.08 = hypotenuse²
Hypotenuse = 627.009
Distance between train X and train Y at 5:50pm is 627.009 km.
c) Distance of train X from Evas station = 485.48km
Speed = 142 km/h
Time taken = distance / speed
Time taken = 485.48 / 142
Time taken by train X to reach station is 3.42 h
Distance of train Y from Evas station = 396.8 km
Speed = 128 km/h
Time taken = distance / speed
Time taken = 396.8 / 128
Time taken by train Y to reach station is 3.1 h
Therefore, train Y will arrive station first.
