Step-by-step explanation:
There are 80 people in a choir.
Half the people in the choir are women.
The number of men in the choir is one quarter of the number of women.
The rest of the people in the choir are children.
the number of children in the choir : the number of men in the choir = n : 1
Work out the value of n.
You must show how you get your answer.
There are 30 children in the choir
Number of people in the choir = 80
Number of women = 1/2 × 80 = 40.
Number of men = 1/4 × 40 = 10
Therefore, the number if children will be:
Men + Women + Children = 80
10 + 40 + n = 80
n = 80 - 40 - 10
n = 50
There are 30 children in the choir.

The way trees are planted are very important because you have to care for it a lot. if it isn't done correctly then the tree will die. Trees need lots of water, sunshine. if the tree isn't correctly planted then it will just be a fail of getting a tree. millions of trees keeps us living and gives us lots of oxygen.
i will only say 3 ways
1.give it water
2.let it touch with sunlight

Assume that the mean of a dataset is 100 and the standard deviation is 5. If we multiply each value in the data by 2, what would be the new standard deviation?
Answer:
7
Step-by-step explanation:
Using statistical concepts, it is found that the new standard deviation of the variable would be of 10.
When a constant is multiplied to each data in a variable:
The mean is multiplied by this constant.The standard deviation is multiplied by this constant.In this problem, the standard deviation of the variable is 5, multiplied by 2, hence:
5 x 2 = 10
The new standard deviation of the variable would be of 10.

The fastest elevators in the Burj Khalifa can travel 330 feet in just 10 seconds. How far does the
elevator travel in 11 seconds? Explain your reasoning.
Answer:
363 feet = 11 seconds
Step-by-step explanation:
330 feet = 10 seconds
=> 330/10 feet = 10/10 seconds
=> 33 feet = 1 second
=> 33 × 11 feet = 11 × 1 second
=> 363 feet = 11 seconds.
Therefore, the Burj Khalifa can travel 363 feet in 11 seconds.
Answer:
[tex]363ft[/tex]
Step-by-step explanation:
First we know that the elevator can travel 330 feet in just 10 seconds. That's can be interpret as:
[tex]\frac{330ft}{10s} = \frac{33ft}{1s}[/tex]
How you can see each second the elevator travel 33 feet so if you want to know how many travel in 11 second you only have to multiply by 11 the 33ft.
[tex]33ft \cdot 11s = 363ft[/tex]
Apples are 88 cents a pound if I have $6 how many pounds of apples can I buy with the $6 round to the nearest whole pound
Answer:
7 lbs
Step-by-step explanation:
Answer:
You can buy about 7 pounds of apples.
Step-by-step explanation:
Since we're dealing with cents, we'll change 88 to 0.88 so we can solve.
I personally did 0.88p = 6, where p = pounds, and then I divided 0.88 on both sides.
Of course you could just divide normally,
6 ÷ 0.88, either way it equals 6.81 repeating.
When you round that up, it will equal to 7.

Michelle bought 12 cookies and 8 cupcakes for $72. Jana bought 5 of the same cookies and 10 of the same cupcakes for $50. What is the price of each item?
Answer:
Step-by-step explanation:
x = cookies
y= cupcakes
12x + 8y = 72
5x + 10y = 50
60x + 40y = 360
-20x - 40y = -200
40x = 160
x = $4 each cookie
12(4) + 8y = 72
48 + 8y = 72
8y = 24
y = $3 each cupcake
What's the answer to 13 times 12

Which package has the better unit price per ounce?
Answer:
The 48-pack has the better unit price per bottle
Step-by-step explanation:
Given the two packages of same brand water bottles, where:
48-pack of 8 oz bottles = $5.88 28-pack of 10 oz bottles = $5.98We can compare which package has the better unit price per bottle by finding out how much each bottle costs, and the price per fluid ounce (fl oz) of each bottle.
48-pack:For the 48-pack, divide the total cost of $5.88 by the number of bottles for the whole package to determine the price of each bottle.
[tex]\mathsf{\frac{\$5.88} {48\:bottles}\:=\:\$0.1225\:per\:bottle}[/tex]
Next, divide the price per bottle by 8 ounces to find the cost per fluid ounce of the 48-pack:
[tex]\mathsf{\frac{\$0.1225} {8\:fl\:oz}\:=\:\$0.015\:per\:fl\:oz}[/tex]
28-pack:Similar to our solution for the 48-pack, we can determine the price of each bottle in a 28-pack by dividing the total cost of $5.98 by 28 bottles to determine the price of each bottle.
[tex]\mathsf{\frac{\$5.98} {28\:bottles}\:=\:\$0.21357\:per\:bottle}[/tex]
Next, divide the price per bottle by 10 ounces to find the cost per fluid ounce of the 28-pack:
[tex]\mathsf{\frac{\$0.21357} {10\:fl\:oz}\:=\:\$0.0214\:per\:fl\:oz}[/tex]
Answer:Therefore, the 48-pack of 8-ounce bottles has a better unit price per bottle of $0.12 than the unit price per bottle of the 28-pack of water bottles of $0.21.

Points C open parentheses negative 5 comma 8 close parentheses and D open parentheses 2 comma 5 close parentheses lie on line C D. If points C apostrophe and D apostrophe are created by translating points C and D left 6 units, what is the slope of line C apostrophe D apostrophe ?
We want to find the slope of the line that connects points C' and D'. We will find that the slope is -3/7.
First, we start with the points:
C = (-5, 8)D = (2, 5)Now we create points C' and D' by translating points C and D to the left by 6 units, this means that we need to subtract 6 in the x-value of each point, so we will have:
C' = (-5, 8) + (-6, 0) = (-5 - 6, 8) = (-11, 8)D' = (2, 5) + (-6, 0) = (2 - 6, 5) = (-4, 5)And we know that if a line passes through points (x₁, y₁) and (x₂, y₂) the slope is given by:
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Then the slope that connects points C' and D' is:
[tex]a = \frac{5 - 8}{2 - (-5)} = \frac{-3}{7}[/tex]

To solve the equation, you have to to isolate the variable. So, first you subtract both sides by 7.
x +7 - 7 = -2 - 7
When you simplify further,
x = -9.

Brian needs to make a total of 80 deliveries this week. So far he has completed 64 of them. What percentage of his total deliveries has Brian completed?
The percentage of his total deliveries has Brian completed is 80%.
What is percentage?
In a percentage, the total value is always 100, making it a ratio or fraction. For instance, Sam received a score of 30% on his arithmetic test, which is 30 out of a possible 100. In terms of ratio, it is expressed as 30:100 and as a fraction as 30/100. A certain portion or amount in every hundred is referred to as a percentage. The fraction is denoted by the sign "%," and its denominator is 100.
Here the given
Total number of deliveries = 80
The number of deliveries completed by Brian= 64
Now the percentage of deliveries completed by him is,
=> [tex]\frac{Number of deliveries completed by brian}{Total number of deliveries}[/tex] × 100
=> [tex]\frac{64}{80}[/tex] × 100
=> [tex]\frac{4}{5}[/tex] ×100
=>4×20 = 80%
Hence the percentage of his total deliveries has Brian completed is 80%.
