Jamal bought a package of 50 water balloons and used 35 of them with his friends. What percent of the water balloons did Jamal use?
Answer:
70%
Step-by-step explanation:
Math
Answer:
70%
Step-by-step explanation:
HOW TO:
To convert a number into percent multiple it by 100 and then add the percent sign. These examples convert the numbers 23 and 158 to percents. To convert a number with a decimal into percent, multiply it by 100 and add the percent sign.
Figure Out:
50 = 100%
25 = 50%
Therefore, the only legible solution would be 70%

Answer:
$2.97
Step-by-step explanation:
- add together the prices of the items; 22.50 + 13.50 = 36
- multiply the total by the tax; 36 x 8.25% or 36 x 0.0825 = 2.97

Answer:
x=3
Step-by-step explanation:
Answer:
Perimeter of the first triangle :[tex] \longmapsto(x - 4) + (x - 5) + 5 \\ = x - 4 + x - 5 + 5 \\ = \boxed{2x - 4}[/tex]
Perimeter of the second triangle :[tex] \longmapsto(x - 10) + 10 + 16 \\ = x - 10 + 10 + 16 \\ = \boxed{x + 16}[/tex]
Now, it is given that the two triangles have same perimeter
So equating the value of the perimeter of the two triangles, we get
[tex] 2x - 4 = x + 16 \\2x - x = 16 + 4 \\ \boxed{ x = 20}[/tex]
Therefore, the value of x is 20
x = 20 is the right answer.46. Mean of n observations is š. If each of these
observations is increased by 1, 2, 3, 4...n, respec-
tively, then what will be their mean?
==============================================================
Explanation:
Consider the set
[tex]\left\{x_1,x_2,x_3,\ldots,x_n\right\}\\\\[/tex]
which has n items in it. We don't know anything about any individual item, but what we do know is that the mean is S.
So,
[tex]\text{mean} = \frac{\text{sum of values}}{\text{number of values}}\\\\\text{mean} = \frac{x_1+x_2+x_3+\ldots+x_n}{n}\\\\S = \frac{x_1+x_2+x_3+\ldots+x_n}{n}\\\\nS = x_1+x_2+x_3+\ldots+x_n\\\\x_1+x_2+x_3+\ldots+x_n = nS\\\\[/tex]
In short, the sum of the values [tex]\left\{x_1,x_2,x_3,\ldots,x_n\right\}\\\\[/tex] is exactly nS, where S is the mean of the same set.
------------------------
Next, we add 1 to [tex]x_1[/tex], add 2 onto [tex]x_2[/tex], etc to form this new set
[tex]\left\{x_1+1,x_2+2,x_3+3,\ldots,x_n+n\right\}\\\\[/tex]
Let's find the mean like so
[tex]\text{mean} = \frac{\text{sum of values}}{\text{number of values}}\\\\\text{mean} = \frac{(x_1+1)+(x_2+2)+(x_3+3)+\ldots+(x_n+n)}{n}\\\\\text{mean} = \frac{\left(x_1+x_2+x_3+\ldots+x_n\right)+\left(1+2+3+\ldots n\right)}{n}\\\\\text{mean} = \frac{nS+0.5n(n+1)}{n}\\\\\text{mean} = \frac{n(S+0.5(n+1))}{n}\\\\\text{mean} = S+0.5(n+1)\\\\[/tex]
which is why S+0.5(n+1) is the answer
------------------------
Let's look at a concrete example.
Consider the set {1,7,10} which has n = 3 items in it.
Its mean is,
S = (1+7+10)/3 = 18/3 = 6
Now increase the items in {1,7,10} by adding on the values {1,2,3} to each element in the order shown
1+1 = 2
7+2 = 9
10+3 = 13
So {1,7,10} becomes {2,9,13}
The mean of the new set {2,9,13} is...
mean = (2+9+13)/3 = 24/3 = 8
Notice how,
newMean = S + 0.5(n+1)
newMean = 6 + 0.5(3+1)
newMean = 8
which helps us see how the formula works and partially confirm the answer. While this example isn't definitive proof, it's still handy to go over. I recommend forming other sets to check to see that this formula works. Not only do I recommend trying different values, but also a different number of values as well (i.e. increase n to some larger integer).
tom works for a company his normal rate of pay 15 per hour
The amount earned by Tom is the product of the rate per hour and the number of hours worked which is $90.
The amount earned per hour = $15 The number of hours worked = 6 hoursThe amount earned at the normal earning rate can be calculated thus :
Normal rate per hour × number of hoursAmount earned = $15 × 6 = $90
Therefore, the amount earned by Tom after working for 6 hours at the normal rate is $90.

The total pay Tom earn for working 11 hours is £185
Given that Tom is paid £15 if he works for less than 7 hours and then paid 1 1/3 times his normal salary if he works more than 7 hours.
Given that he works for 11 hours, hence:
Pay for the first 7 hours = £15 × 7 hours = £105
Pay for the overtime = 1 1/3 × £15 × (11 - 7) = 4/3 × £15 × 4 = £80
Total pay = £80 + £105 = £185

Find the slope-intercept form of the line passing
through the point (8,7) and parallel to the line
y = - 2x - 5.
Answer:
y = -2x + 23.
Step-by-step explanation:
If the line is parallel to
y = -2x - 5,
that means it has the SAME SLOPE. Parallel lines have the same slope, but they could have different y-intercepts.
The slope intercept form is:
y = mx + b.
m = slope.
b = y intercept.
In this case, the slope is -2.
So we know the answer will have a slope of -2.
So we can write:
y = -2x + b.
We just have to finish the answer by replacing "b" with a number.
To find out what "b" is, we plug in the point (8,7).
To plug this point in, we replace "x" with 8 and "y" with 7.
7 = -2(8) + b.
7 = -16 + b.
Now to get b by itself to solve for b, we have to add 16 to both sides.
7 + 16 = b.
b = 23.
So our final answer is: y = -2x + 23.
21 people travelled to a meeting.
12 used a train.
6 used a car.
7 did not use a train or a car.
Some used a train and a car.
Two people are chosen at random from those who used a train.
Find the probability that both these people also used a car.
Answer:
answer = 1/11
Step-by-step explanation:
The addition rule of probability.
P (T + C) = P(T) + P(C) - P(T ∩ C)
The probability that both these people also used a car given that both of them use a train is 1/11.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
The number of people who used the train and the car.
P (T U C) = 21 - 7 = 14
P(T) = Probability of the number of people who used the train = 12
P(C) = Probability of the number of people who used the car = 6
From the addition rule of probability.
P (T + C) = P(T) + P(C) - P(T ∩ C)
14 = 12 + 6 - P(T ∩ C)
P(T ∩ C) = 12 + 6 - 14 = 18 - 14 = 4
Now,
Two people are chosen.
P(C/T):
= P(T ∩ C) / P(T)
= [tex]^4C_2[/tex] / [tex]^{12}C_2[/tex]
= (4 x 3 / 2) / (12 x 11 / 2)
= 6 / 6 x 11
= 1/11
Thus,
The probability that both these people also used a car given that both of them use a train is 1/11.

2x+7y=3 and x=-4y with substitution ?
Answer:
x=12
y=-3
Step-by-step explanation:
Because we already know what the value of x, we can use that value, -4y, to substitute it into the equation 2x+7y=3.
2(-4y)+7y=3 Simplify.
-8y+7y=3
-y=3 Divide both sides by -1 (to make y positive).
y=-3
Now, we can substitute y into the other equation, x=-4y.
x=-4(-3) Simplify.
x=12
