A restaurant has two different seating options: a table and a family booth. A table can seat 4 people, and a family booth can seat 10 people. The restaurant has a maximum capacity of 242 people. If the restaurant has 19 family booths, which inequality could be used to find t, the number of tables in the restaurant?
Answer:
t ≤ 15
Step-by-step explanation:
Let t = tables
6 * 15 + 2* t ≤ 120
90 + 2t ≤ 120
2t ≤ 30
t ≤ 15

2 Review Homework 2.2.4 Question Help A town has accumulated 5 inches of snow, and the snow depth is increasing by 5 inches every hour. A nearby town has accumulated 7 inches, and the depth is increasing by 2 inches every hour. In about how many hours will the snowfall of the towns be equal?
Answer:
You need to find the equations for each scenario and set them = to each other
Step-by-step explanation:
A) S = 5t + 5
B) S = 7t + 2
Now set them = and solve for t
5t + 5 = 7t + 2
3 = 2t
t = 3/2 of an hr
To check plug in 3/2 into both equations and you should get same answer.

The length of a rectangle is 50 meters. This is 6 meters more than twice the width. Find the width.
Answer:
106 meters
Step-by-step explanation:
50x2=100 100+6=106
Answer: 22
Step-by-step explanation:
50=2x+6
Add negative 6 to both sides (50+ -6) and (6+-6)
Then divide both sides by 2 (2x/2) and (44/2)
That is how you properly solve this 2 step equation

2) Consider the following system of three equations:
(I added an image)
===============================================
Explanation:
Subtract the second equation from the first one
[tex]\ \ \ \ 3x+3y-5z = 4 \ \ ... \text{ eq 1}\\-(4x-4y+z = -1) \ \ ... \text{ eq 2}\\---------\\\ \ -x+7y-6z = 5[/tex]
Let's call that result equation 4.
Now focus on equation 3 and equation 4
equation 3 is -x+7y-6z = 2
equation 4 is -x+7y-6z = 5
Note how the left hand sides are identical, but the right hand sides are different. This means that we have an inconsistent system with no solutions. No matter what numbers we pick for x,y,z, there is no way to make all three given original equations to be true.
10. Write the fraction 9/50 as a decimal. If
necessary, round your answer to the nearest
hundredth.
A 0.28
© 0.5
B 0.18
D 0.09
Answer:
0.18
Step-by-step explanation:
9/50 is the same as 18/100, we know this because if we multiply both 9 and 50 by 2, it gives us 18/100. 18/100 can be turned into the decimal, 0.18, so your answer is 0.18
I hope this helps :)
Suppose that a recent poll found that 50 % of adults in a certain country believe that the overall state of moral values is poor.

Answer: 3.75
Step-by-step explanation:
P=0.50, n=15
np= 0.5x15 gives 7.5
n(1-p)= 15x(1-0.5)=7.5
Both are greater than 5
Then Mean, u=np;15x0.5=7.5
Standard deviation, √np(1-p)
15x0.5(0.5)= 3.75

Answer:
Part A: 15.55
Part B: 0.45
Step-by-step explanation:
Part A:
The giraffe is already 14.29 so when you add the length of its tongue (equation 14.29 + 1.26) then that would equal 15.55
Part B:
The giraffe is trying to eat some leaves that are 16 feet above the ground so you would subtract 16 - 15.55 to see how much farther it needs to reach, so the answer is 0.45.
(This is what I got, I apologize if I get this wrong. If I messed up on something, someone please correct me, thank you and have a nice day!)
Answer:
Part A: It can reach 15.55 feet.
Part B: Need to reach 0.45 feet farther to get to the leaves of a 16 feet tree.
Step-by-step explanation:
giraffe + tongue = reach
14.29 + 1.26 = 15.55
tree height - giraffe reach = extra distance
16 - 15.55 = 0.45 feet

What is the solution to the inequality -2.1x + 2.9 > 15.5?
Answer:
x<−6
Step-by-step explanation:
Let's solve your inequality step-by-step.
−2.1x+2.9>15.5
Step 1: Subtract 2.9 from both sides.
−2.1x+2.9−2.9>15.5−2.9
−2.1x>12.6
Step 2: Divide both sides by -2.1.
−2.1x−2.1>12.6−2.1
x<−6
7.82 change the decimals to fractions reduced to lowest terms.
Answer:
7.82 = 391
50
= 741
50
as a fraction
To convert the decimal 7.82 to a fraction, just follow these steps:
Step 1: Write down the number as a fraction of one:
7.82 = 7.82
1
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As we have 2 numbers after the decimal point, we multiply both numerator and denominator by 100. So,
7.82
1
= (7.82 × 100)
(1 × 100)
= 782
100
.
Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(782,100) = 2. So,
(782÷2)
(100÷2)
= 391
50
when reduced to the simplest form.
As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 782
100
is also equal to 741
50
when expressed as a mixed number.
