At a restaurant last night, 8 people ordered salads, 10 ordered steaks, 18 ordered chicken, and 14 ordered pasta.
From this information, how many people out of 100 would you expect to order chicken?
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

You buy bananas and strawberries in the ratio of 3 : 4. Choose the expression for the number of bananas you buy when you buy n strawberries.
ANSWER: 3/4n
Answer:
[tex]\dfrac{3}{4}n[/tex]
Step-by-step explanation:
The ratio of bananas to strawberries is 3:4.
That means for every 3 bananas you buy, you buy 4 strawberries.
That also means that for every 4 strawberries you buy, you buy 3 bananas.
The number of bananas you buy is 3/4 of the number of strawberries you buy.
If you buy n strawberries, then the number of bananas you buy is
[tex]\dfrac{3}{4}n[/tex]

Answer:
lenght = 2x + 3
breadth = x - 1
perimeter = 40
Now,
perimeter = 2(l+b)
40= 2( 2x + 3 + x - 1)
40= 2(3x - 2)
40 = 6x- 4
40+4 =6x

5. Write an equation of a Ine with a slope of -5 that passes through the
point (-3, 8).
Answer:
y = -5x + -7
Step-by-step explanation:
y = mx + b
y = -5x + b
To find b... 8 = -5*-3 + b
8 = 15 + b
8 - 15 = b
-7 = b
So....y = -5x + -7

I need help ASAP pls show ur work and ty
Answer:
Step-by-step explanation:
x + 0.7 = 1 - 0.2x
Add 0.2x to both sides
x + 0.2x + 0.7 = 1 - 0.2x + 0.2x
1.2x + 0.7 = 1
Subtract 0.7 from both sides:
1.2x + 0.7 - 0.7 = 1 - 0.7
1.2x = 0.3
Divide both sides by 1.2:
1.2x/1.2 = 0.3/1.2
x = 0.25
Answer:
X=0.25
Step-by-step explanation: x + 0.7 = 1 - 0.2x
Add 0.2x to both sides
x + 0.2x + 0.7 = 1 - 0.2x + 0.2x
1.2x + 0.7 = 1
Subtract 0.7 from both sides:
1.2x + 0.7 - 0.7 = 1 - 0.7
1.2x = 0.3
Divide both sides by 1.2:
1.2x/1.2 = 0.3/1.2
x = 0.25

The Clark family went out to dinner. If their dinner bill came to $81.50 and they wish to leave a 18% tip, how much should they tip?
Answer: The correct answer is B.
Step-by-step explanation:
We are given the cost of restaurant meal of M. Clark is $25.50.
and she has given 20% of the meal's cost as a tip to the waiter.
Step 1: Calculating the amount of tip paid
Total tip paid = $5.1
Step 2: To find the total amount, we add the cost of the meal and the tip paid
Total amount = Cost of the meal + Tip paid
Total amount = $25.50 + $5.10
Total amount paid by Ms. Clark = $30.6

Which equation models the statement shown?
y varies directly with x and y = 25 when r = 5.
Answer:
xy=5
Step-by-step explanation:
from the question, y varies directly with x and y
Then y ∝ xy
If we introduce proportionality sign we have
y=r xy
Where r= proportionality constant
Then if we substitute the given values
y = 25 when r = 5.
We have
y=r xy
25=5xy
Divide both sides by 5
xy=25/5
xy=5
Hence, equation that models the statement is xy=5
Help I need an awnser
Answer:
x=1
Step-by-step explanation:
Distribute 5/8 to x and -1/3 which will result you in 5/8x - 5/24
The equation now looks like this:
5/8x - 5/24= 5/12
Move -5/24 to the other side by adding 5/24 on both sides
5/8x - 5/24 + 5/24 = 5/12+5/24
(Multiply 2 and 5/12 on both the numerator and denominator which will result you to 10/12 add 5/24 which is 15/24)
Result:
5/8x=15/24
Multiply by 8/5 on both sides:
x=1

Answer x=22/5 or 4.4
Step-by-step explanation:
1. Combine like terms
15x-12=54
2. Add 12 to both sides
15x=66
3. Divide both sides by 15
15x/15=66/15
4. x=22/5 or 4.4
9514 1404 393
Answer:
x = 4.4
Step-by-step explanation:
This equation has x-terms on one side of the equal sign and constants on both sides.
First, collect terms.
15x -12 = 54
Then add the opposite of the constant that is on the same side as the x-term.
15x = 66
Now, divide by the coefficient of x.
x = 66/15 = 22/5
x = 4.4

4/2n+5/3c=1
Solve for c.
-Multiply both sides by (blank) to clear fractions.
Answer:
We conclude that:
[tex]c=-\frac{5n}{3\left(-n+2\right)};\quad \:n\ne \:2[/tex]
Step-by-step explanation:
Given the expression
[tex]\frac{4}{2n}+\frac{5}{3c}=1[/tex]
Let us solve for 'c'
[tex]\frac{4}{2n}+\frac{5}{3c}=1[/tex]
Least Common Multiplier of 2n, 3c: 6nc
Now multiply both sides by LCM = 6nc
[tex]\frac{4}{2n}\cdot \:6nc+\frac{5}{3c}\cdot \:6nc=1\cdot \:6nc[/tex]
Simplify
[tex]12c+10n=6nc[/tex]
Subtract 10n from both sides
[tex]12c+10n-10n=6nc-10n[/tex]
Simplify
[tex]12c=6nc-10n[/tex]
Subtract 6nc from both sides
[tex]12c-6nc=6nc-10n-6nc[/tex]
Simplify
[tex]12c-6nc=-10n[/tex]
Factor 12c - 6nc = 6c(2-n)
[tex]6c\left(2-n\right)=-10n[/tex]
Divide both sides by 6(2-n); n≠2
[tex]\frac{6c\left(2-n\right)}{6\left(2-n\right)}=\frac{-10n}{6\left(2-n\right)};\quad \:n\ne \:2[/tex]
simplify
[tex]c=-\frac{5n}{3\left(-n+2\right)};\quad \:n\ne \:2[/tex]
Therefore, we conclude that:
[tex]c=-\frac{5n}{3\left(-n+2\right)};\quad \:n\ne \:2[/tex]

Use your knowledge on the triangle proportionality theorem to find the missing side length indicated. Be sure to explain the proportion you used.
Answer:
? = 4.29
Step-by-step explanation:
Remark
Let x be the question mark. You get the proportionality by using the dimensions of the little triangle to the dimensions of the large triangle.
Equation
14/(14+ 4) = 15/(x + 15) Combine like terms on the left
14/18 = 15/(x + 15) Cross multiply
14*(x + 15) = 18 * 15 Simplify the right
14(x + 15) = 270 Divide by 14
x + 15 = 270 / 14
x + 15 = 19.29 Subtract 15 from both sides
x = 19.29 - 15
x = 4.29
