Rounding to the nearest tenth, the circumference of a penny is approximately 6.0 cm.
To find the circumference of a penny, we use the formula for the circumference of a circle:
Circumference = π * diameter
Since the penny's width is given (which is the same as the diameter), we can plug in the values:
Circumference = 3.14 * 1.9 cm
Now, calculate the circumference:
Circumference ≈ 5.966 cm
Rounding to the nearest tenth, the circumference of a penny is approximately 6.0 cm.

Eric is getting his mountain climbing cerificate. There are 63 days that Eric climbs for 2 hours, there are 97 days that he climbs for 3 hours. How many more hours does Eric need to climb until he earns a certificate for climbing 500 hours?
Eric's total hours climbed so far are 417 hours. To meet his goal of a 500-hour certificate, he still needs to climb for 83 additional hours.
Explanation:The question pertains to Eric's mountain climbing practice. To find how many more hours does Eric need to climb to earn his 500-hour certificate, we need to calculate the total hours he has already climbed by multiplying the number of days he climbed by the number of hours he climbed each day.
So, for the 63 days Eric climbed for 2 hours each day, that's 63 * 2 = 126 hours.
And for the 97 days he climbed for 3 hours each day, that's 97 * 3 = 291 hours.
Now, we add these two amounts together: 126 hours + 291 hours = 417 hours.
Since he is aiming for a 500-hour certificate, we subtract the hours he has already climbed from this total: 500 hours - 417 hours = 83 hours
Therefore, Eric needs to climb for 83 more hours to earn his 500-hour certificate.

A game involves spinning this spinner. What is the probability of the pointer landing on Y ?
R R R R B B G Y
1. 1 / 8
2. 1 / 2
3. 5 / 8
4. 2 / 8
The probability of the pointer landing on Y in the spinner game is 1. 1/8, as there is only one Y segment out of a total of 8 segments.
In the given question there is a probability scenario involving a spinner divided into segments that represent different outcomes. The spinner has segments labeled R, B, G, and Y, which represent the colors red, blue, green, and yellow respectively.
To find the probability of the pointer landing on Y (P(Y)), we need to count the total number of segments and determine how many of those are labeled Y.
Given the spinner segments R R R R B B G Y, there is a total of 8 segments.
Since only one of these segments is labeled Y, the probability of the pointer landing on Y is the number of Y segments divided by the total number of segments:
P(Y) = Number of Y segments / Total number of segments = 1 / 8
Therefore, the correct answer is option 1, which is a probability of 1 / 8.

Quadrilateral IJKL is the result of a ________of quadrilateral ABCD . Therefore, the quadrilaterals are_________
Answer:
Transformation, similar
Step-by-step explanation:
Given is a graph with two quadrilaterals IJKL and ABCD
On comparing these we find that the sides of IJKL are proportional to the sides of ABCD. Also the angles of the quadrilateral between pair of sides of IJKL are congruent with angles of the quadrilateral of ABCD.
Hence we can say these two quadrilaterals are similar
Also we can find that ABCD is obtained from IJKL by a set of a series of transformations as reflection on y axis, dilation of sides proportionally and shifting vertically.
Thus the answers for fill in the blanks are
Quadrilateral IJKL is the result of a ___transformation_____of quadrilateral ABCD . Therefore, the quadrilaterals are____similar_____
A size 8 kids shoe measures 9 2/3 inches. If 5 pairs of size 8 shoes are lined end to end, then how many inches will they cover?
A. 36 2/3 b. 48 1/3 c. 77 1/3 d. 62
Final answer:
To find the total length that 5 pairs of size 8 shoes will cover, multiply the length of one pair by the number of pairs. The total length will be 48 1/3 inches.
Explanation:
To find the total length that 5 pairs of size 8 shoes will cover, we need to multiply the length of one pair by the number of pairs. Since a size 8 kids shoe measures 9 2/3 inches, we can multiply this by 5 to find the total length.
Step 1: Convert the mixed number,16/3, to an improper fraction: 9 2/3 = (9*3 + 2)/3 = 29/3 inches.
Step 2: Multiply the length of one pair by the number of pairs: (29/3) * 5 = 145/3 inches.
Step 3: Simplify the fraction: 145/3 = 48 1/3 inches.
Given the figure below, find the values of x and z.
Answer:
x = 14° and z = 83°
Step-by-step explanation:
We know that the vertical angles of intersecting lines are equal.
Thus, 13x - 85 = 97
i.e. 13x = 97 + 85
i.e. 13x = 182
i.e. [tex]x=\frac{182}{13}[/tex]
i.e. x = 14°
Since, the sum of all the four angles formed by intersecting line is 360°.
We get,
(13x-85) + 97 + 2z = 360° (Take 2z as opposite angles are equal)
i.e. 2z = 360 - 97 + 85 - 13 × 14
i.e. 2z = 360 - 12 - 182
i.e. 2z = 360 - 194
i.e. 2z = 166
i.e. [tex]z=\frac{166}{2}[/tex]
i.e. z = 83°
Hence, we get the angles x = 14° and z = 83°.

A bookstore has a sale:
Jim wants to buy two books for $10.00 each. By what percent is the total cost of the two books reduced during the sale?
We cannot calculate the percentage reduction in price because the question does not provide enough information. We need the sale price, as well as the original price, to determine the percentage reduction. The formula used is Percentage Reduction = ((Original Price - Sale Price) / Original Price) * 100.
Explanation:To determine the percentage by which the total cost of the two books is reduced during the sale, we first need to know the original price and the sale price of the books. The original price for two books, according to Jim, is $10 each which means the total cost is $20. However, we are not given the information about the sale price of the books, hence we cannot calculate the percent reduction.
We use the formula: Percentage Reduction = ((Original Price - Sale Price) / Original Price) * 100. Despite having the original price, without information on the sale price, solving the problem is impossible.

helga works 20 hours per week she makes $12 a hour how do you translate into a algebraic equation
The algebraic equation that represents Helga's earnings per week, where she works 20 hours at $12 per hour, can be written as y = 20x. In this equation, 'y' represents her weekly earnings and 'x' stands for her hourly rate. Substituting x with 12 will compute Helga's total weekly earnings which equates to $240.
Explanation:The problem states that Helga works 20 hours per week and earns $12 for each hour of work. This situation can be translated into a simple algebraic equation, which is the tool you use in mathematics to represent real-world situations. In this case, the total earnings Helga gets every week is the product of the hours she works and her hourly rate. This can be expressed by the following equation:
y = 20x
Where:
y represents Helga's weekly earnings.x corresponds to Helga's hourly wage of $12.So, if you substitute x with 12 in the equation, you would get:
y = 20 * 12 = 240
Therefore, Helga earns $240 weekly.
