Step-by-step explanation:
Terri opened a bag of jelly beans. After counting and sorting them, she realized that 20% of the jelly beans were red. Which is NOT equivalent to 20%?
A. 0.2
B. 1:5
C. 4/16
(Please Explain)
Answer:
The answer is C
Step-by-step explanation:
A. 0.2 = 20%
B. 1/5 = 20% / 1 divided by 5 = .2
C. 4/16 = 1/4 = 25% / 1 divided by 4 = .25
The expression not equivalent to the 20% will be 4/16.
What is the percentage?It is the ratio of two numbers expressed as a decimal of 100 parts. It is a measurement used to compare two sets of data, and it is stated as a percentage using the percent sign. Percentages are often and in many different contexts used.
It is given that the expression is 20%.
We have to find the equivalent value of 20%
Expressions that function identically while having distinct appearances are called equivalent expressions. If two algebraic expressions are equivalent, then they both have the same result when the same value of the variable is entered.
It can be written in different forms as,
=20/100
=1/5
=0.2
Thus, the nonequivalent expression of the % will be 4/16.

Answer:
c) Punishments in the Code of Hammurabi were adjusted depending on the status of the perpetrator and the victim.
Step-by-step explanation:
The Code of Hammurabi reflected the social hierarchy of ancient Babylonia in that it differentiated punishments based on the social status of the perpetrator and the victim. For example, the code stipulated different punishments for crimes committed by a nobleman versus those committed by a commoner. This demonstrates that ancient Babylonian society was structured into a hierarchy, with different levels of privilege and responsibility assigned based on social status. The Code of Hammurabi, then, serves as a tangible expression of this social hierarchy, showing the ways in which the laws of the land reflected and reinforced existing power dynamics.

18 cups, 2 gallons, 6 pints, 6 quarts,
Answer:
6 pints, 18 cups, 6 quarts, 2 gallons
Step-by-step explanation:
1 gallon = 16 cups
2 gallons = 32 cups
18 cups, 32 cups, 6 pints, 6 quarts
1 pint = 2.4 cups
6 pints = 14.4 cups (2.4*6)
18 cups, 32 cups, 14.4 cups, 6 quarts
1 quart = 4 cups
6 quarts = 24 cups (4*6)
18 cups, 32 cups, 14.4 cups, 24 cups
=
18 cups, 2 gallons, 6 pints, 6 quarts
↓
6 pints, 18 cups, 6 quarts, 2 gallons

what value of x makes this equation true -(x+3)=2(x-3)
A. 0
B. 1
C. 2
D. 3
Answer:
To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:
Step 1: Distribute the negative sign on the left side of the equation:
-(x + 3) = 2(x - 3)
=> -x - 3 = 2(x - 3) (using the distributive property)
Step 2: Expand the right side of the equation:
-x - 3 = 2x - 6
Step 3: Add x to both sides of the equation to isolate the x term on one side:
-x + x - 3 = 2x + x - 6
=> -3 = 3x - 6
Step 4: Add 6 to both sides of the equation:
-3 + 6 = 3x - 6 + 6
=> 3 = 3x
Step 5: Divide both sides of the equation by 3 to solve for x:
3/3 = 3x/3
=> 1 = x
So, the correct value of x that makes the equation true is B. 1.
PLEASE MARK BRAILYISTT :D
Answer:
B, one
Step-by-step explanation:
In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

What is P(less than 5)?
Write your answer as a fraction or whole number.
Answer:
this probability is 3/4.
Step-by-step explanation:
The spinner has the numbers 2, 3, 4, and 5. Since the question asks for the probability of spinning a number less than 5, we need to consider the numbers 2, 3, and 4.
Out of the four numbers on the spinner, three of them (2, 3, and 4) are less than 5.
Therefore, the probability of spinning a number less than 5 is 3 out of 4.
Answer:
You spin the spinner once.

PLEASE HELP ASAP!!!!! a simulation by tossing a coin to model whether these puppies will be male or female. • Let heads (H) = female puppy • Let tails (T) = male puppy The results of the simulation are: 1. TTTT 6. HHHH 2. TTTT 7.HTHT 3. THTH 8. HHHH 4. HTTT 9. THTH 5. TTTT 10. HHHH What is the estimated probability that at least two of the puppies will be male?
Answer:
7/10 or 70%
Step-by-step explanation:
There has to be at least two T in each result of the simulation. This means you can also have 3 T's and 4 T's in the result.
These are the results that qualify as having at least two T's.
1. TTTT, 2. TTTT, 3. THTH, 4. HTTT, 5. TTTT, 7. HTHT, 9. THTH
That is 7 out of the 10 results which is 7/10 or 70%

Answer:
x÷3+5=6
Step-by-step explanation:
1. (x/3)+5=6
2. x/3=1/3x
3. subtract 5 from both sides and get 1/3x=1
4. multiply both sides by 3 because if u want to find what x equals u need to multiply it so its not 1/3x

Two friends, Rahul and Arun, took summer jobs. The equation y = 17.3x represents Arun's earnings in dollars and cents, y, for working x hours. The graph below represents Rahul's earnings in dollars and cents, y, for working x hours.
How much more does Rahul earn per hour than Arun?
Answer: Rahul earns 3.5 dollars more per hour than Arun.
Step-by-step explanation:
17.3 is the slope of Arun's earnings. To find what Rahul makes in an hour, you can find the slope of his graph below.
Use the two points, (10,208) and (20, 416)
Use the formula for calculating slope:
416-208=208
20-10=10
---------------------
208/10= 20.8
Rahul's equation can be set up like this:
y=20.8x
Subtract:
20.8-17.3=3.5
Therefore, Rahul earns 3.50 dollars more per hour than Arun.
Solve for x

Alexis went back-to-school shopping. She purchased one pack of markers for $2.50, a lunchbox for $5.25, and two shirts for $7.99. She used a 20%-off coupon. How much did Alexis owe? Show your work.
Answer: $12.60
Step-by-step explanation:
after adding to the total with the markers, lunchbox and shirts you get $15.75 then multiply the normal price $15.75 by 20 then divide it by one hundred and you will get $3.15 as your saved amount and you will then do 15.75-3.15= 12.6 make sure to put a 0 after the 6 making it 60.
(2.50+5.25+7.99= $15.75)
(15.75-3.15= 12.60)
15 POINTS IF SOMEONE ANSWERS QUICK
Answer:
The 16 cases will fit the box as shown.
Step-by-step explanation:
One disk case has the dimensions 14.2 cm by 19.3 cm, with thickness 1.6 cm.
Temporarily ignoring the 14.2 cm and 19.3 cm measurements, we multiply this 1.6 cm thickness by 16, obtaining a total thickness for the stack of cases of 25.6 cm.
1) The 16 cases, arranged as shown, and measuring 25.6 cm from left to right in this diagram, will fit within the 26 cm horizontal distance shown.
2) The horizontal length of each case is 14.2 cm. Stacked as shown, the 16 cases will fit within the 15 cm depth of the box.
3) The vertical measurement of each case is 19.3 cm. The 20 cm vertical measurement of the box can accommodate this 19.3 height within 20 cm.
All indications are that the 16 cases will fit comfortably inside the box.
Answer:
16 discs capacity of the cuboid.
Step-by-step explanation:.
for simplicity...
i would just divide 26cm to 1.6cm = 16 .25
therefore, 16 discs capacity of the cuboid.
