Answer:
36 people would order chicken.
Step-by-step explanation:
Case I: (50 People in Total)
Total Number of People Ordering=8+10+18+14=50
Percentage of People ordering chicken=people ordering chicken/total number of people=18/50=0.36%
Case II: (100 People in Total)
Number of People ordering chicken=percentage of people ordering chicken x total number of people=0.36 x 100=36
oil is leaking out of a tank. the depth of oil in the tank for 60 seconds is shown below. use the graph to work out the rate of decrease of depth, in cm/s, at 10 seconds. you must show your working.
Answer:
2.24
Step-by-step explanation:
The rate of decrease at 10 seconds is - 0.642.
What is the formula for exponential growth and exponential decaying function?The formula for exponential growth is y = y₀.e^(kt).
The formula for exponential decay is y = y₀.e^(-kt).
From the graph, we conclude that it is an exponentially decaying function.
At t = 10, depth = 60 and at t = 0 depth = 112
(as every box represents 4 units).
So, the rate of decrease can be obtained by,
112 = 60.e^(-10k).
e^(-10k) = 1.86.
lne^(-10k) = ln1.86.
- 10k = 6.42.
k = - 0.642.
The rate of decrease at 10 seconds is - 0.642.

if there are 3 to 7 of girls and boys what is the percentage of boys if there are 50 in a class
Answer:
35 boys
Step-by-step explanation:
Answer:
15/35 or 43% if your going to the nearest whole number so there are 35 boys and 15 girls
Step-by-step explanation:
Let x = the number of boys
Let 50 - x = the number of girls
Girls/Boys: 3 = 50 - x Cross Multiply
7 x
3x = 350 - 7x
10x = 350
x = 35 boys
50 - x = 15 girls
Check: 15/35 = 3/7

A gardener plans to extend the length of a rectangular garden. Let x represent the garden's original length. The expression 4(x+7) represents the area of the extended garden. WHen asked for the area of the extended portion the gardener incorrectly said it was 11 square feet. Describe the error the gardener made.
Answer:
The answer is "[tex]4 \cdot 7[/tex]".
Step-by-step explanation:
In the question the total given value =4(x+7). if we add the value it will be 11 but if we multiply the value it is equal to [tex]4 \cdot 7[/tex].
The error gardener made is that the area of the extended portion is 28 ft² instead of 11 ft².
Given to us
The original length of the garden is x.
The Area of the extended garden is 4(x+7).
Area of the Extended GardenGiven to us is the area of the complete garden, therefore, comparing the expression with the area of a rectangle,
[tex]\text{Area of rectangle}= \rm{ Breadth \times Length[/tex]
[tex]4(x+7) = Breadth \times Length[/tex]
Therefore, the breadth of the rectangle is 4 feet, since the breadth of the rectangle is not been changed the breadth of the rectangle is same as before, also (x+7) represents the complete length of the garden after it is extended, and since the original length of the garden is x, the length extended is 7 feet.
Area of the only Extended Portion of the GardenWe know that the breadth of the rectangular garden is 4 and the area of extended length is 7, therefore,
The Area of the only Extended Portion of the Garden
= 4 x 7 = 28 ft²
Hence, the error gardener made is that the area of the extended portion is 28 ft² instead of 11 ft².

x square + 12x =1
Answer:
x = - 6 ± [tex]\sqrt{37}[/tex]
Step-by-step explanation:
Given
x² + 12x = 1
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(6)x + 36 = 1 + 36
(x + 6)² = 37 ( take the square root of both sides )
x + 6 = ± [tex]\sqrt{37}[/tex] ( subtract 6 from both sides )
x = - 6 ± [tex]\sqrt{37}[/tex] ← exact solutions

How many integers are there that consist of four digits (from 1000 to 9999) where the first digit is a 5 or an 8 and the third digit is not 5 or 8
Answer:
1600 integers
Step-by-step explanation:
Since we have a four digit number, there are four digit placements.
For the first digit, since there can either be a 5 or an 8, we have the arrangement as ²P₁ = 2 ways.
For the second digit, we have ten numbers to choose from, so we have ¹⁰P₁ = 10.
For the third digit, since it neither be a 5 or an 8, we have two less digit from the total of ten digits which is 10 - 2 = 8. So, the number of ways of arranging that is ⁸P₁ = 8.
For the last digit, we have ten numbers to choose from, so we have ¹⁰P₁ = 10.
So, the number of integers that can be formed are 2 × 10 × 8 × 10 = 20 × 80 = 1600 integers

Kristen is making accessories for the soccer team. She uses 595.56 inches of fabric on headbands for 39 players and 3 coaches. She also uses 343.59 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answer:
22.99 inches
Step-by-step explanation:
According to problem, given data are as follows:
Fabric used for headband = 595.56 inches
Number of headbands made = 39 + 3 = 42
So, Fabric used per headband = 595.56 ÷ 42 = 14.18 inches per headband
Similarly, Fabric used for wristband = 343.59 inches
Number of wristbands made = 39
So, Fabric used per wristband = 343.59 ÷ 39 = 8.81 inches per wristband
So, Fabric used for each player = 14.18 inches + 8.81 inches
= 22.99 inches

P is the amount invested
r is the rate
n is the number of times per year the interest is compounded
t is the number of years
every 6 months is twice a year
