In 56 years, Kevin will be 9 times as old as he is now
How old is Kevin now?
Answers
Answer:
correct answer is 7 years
Step-by-step explanation:
A+56=9(A)
56+9A
A=7
he will be 7 years old he is pretty old
Answer:
Kevin is 7 years old right now.
Step-by-step explanation:
Let x be Kevin's age right now, that's what we're trying to find.
In 56 years, he'll be 9 times older than he is now, so we can say:
x + 56 = 9x
Now we can get the x values on the right side of the equation so that:
56 = 8x
Now solve for x and you have his current age which is 7.
Your science experiment has a percent error of 3%. The estimated weight of your rock sample is 47 grams. What is the actual weight of the rock sample?
A) 44.4g or 41.1gB
B) 44.2g or 50.4g
C) 48.4g or 45.6g
D) 50g or 44g
Answers
Answer:
C) 48.4g or 45.6g
Step-by-step explanation:
To find the actual value of the rock sample, we need to rearrange this formula and solve for the actual value. We can do this by following these steps:
1. Throw away the formula. It's useless and confusing.
2. Look at the rock sample. Is it shiny? Does it have sparkles? Does it look like something a pirate would want?
3. If yes, congratulations! You have a valuable rock sample. If no, sorry, you have a worthless rock sample.
4. Go to the nearest pawn shop and sell your rock sample for cash. Don't forget to haggle.
5. Enjoy your newfound wealth or lack thereof.
No, don't do that, I'm Just Kidding, this is how you get it:
percent error = |(estimated value - actual value) / actual value| x 100%
actual weight = 47 g / (1 - 3% / 100%) or actual weight = 47 g / (1 + 3% / 100%)
actual weight = 47 g / (1 - 0.03) or actual weight = 47 g / (1 + 0.03)
actual weight = 47 g / 0.97 or actual weight = 47 g / 1.03
actual weight ≈ 48.45 g or actual weight ≈ 45.63 g
Rounding to one decimal place, we get:
actual weight ≈ 48.4 g or actual weight ≈ 45.6 g
Therefore, the correct answer is C) 48.4 g or 45.6 g.

Responses
A 3939
B 1616
C 3737
D 1313
E 17
Answers
Answer:
Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16
2+3+5+9+17+22+31+39=128
128/8=16
Write three decimals that are equivalent to 6x1 + 4x1/10
Answers
Explanation: 6x1 + 4x1/10=6+0.4=6.4
The decimal is 6.4 which is equivalent to 6×1 + 4×1/10.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that performs the arithmetic operations are called arithmetic operators.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
Given that the expression as:
⇒ 6×1 + 4×1/10
Apply the arithmetic operations in the terms,
⇒ 6 + 4×0.1
⇒ 6 + 0.4
⇒ 6.4
Thus, the decimal is 6.4 which is equivalent to 6×1 + 4×1/10.

What is the area of the composite figure?
Answers
Answer:
745.4 cm^2
Step-by-step explanation:
The composite figure is made up of a rectangle 25 cm by 20 cm and a semicircle of radius 12.5 cm.
We add the two areas to find the total area.
total area = area of rectangle + area of semicircle
TA = LW + (1/2)(pi)r^2
TA = (25 cm)(20 cm) + (1/2)(3.14159)(12.5 cm)^2
TA = 500 cm^2 + 245.4 cm^2
TA = 745.4 cm^2

To graph the inequality x > -3, draw an open circle on -3 and shade to the left true or false.
Answers
Answer:
False
Step-by-step explanation:
The first part of the statement is correct with it saying to have an open circle on -3, but the shading should go on the right because x is bigger than -3. When you picture a number line, the numbers on the right of -3 are bigger than the numbers on the left.
The statement " To graph the inequality x > -3, draw an open circle on -3 and shade to the left" is wrong.
What is inequality?When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.
The first part of the statement is correct, as it states that an open circle should be placed on -3, but the shading should be placed on the right because x is greater than -3. On a number line, the numbers to the right of -3 are larger than the numbers to the left.

Ms. Ramirez deposited $2,720 into an account that earns 2.35% simple interest annually. She made no additional deposits or withdrawals. What will be the balance in Ms. Ramirez's account in dollars and cents at the end of 6 years?
Answers
Answer:
Ms. Ramirez's account balance at the end of 6 years will be $3,094.20.
Step-by-step explanation:
To calculate the balance in Ms. Ramirez's account, we can use the following formula:
Balance = Principal + Interest
In this case, the principal is $2,720, the interest is 2.35%, and the time is 6 years.
Plugging in these values, we get:
Balance = $2,720 + (0.0235 * $2,720 * 6) = $3,094.20
Therefore, Ms. Ramirez's account balance at the end of 6 years will be $3,094.20.
