The length of the fabric is 4 cm.
Explanation:To find the length of the piece of fabric, we need to divide the area by the width. The area of the fabric is given as 20 cm squared and the width is given as 5 cm. So, to find the length, we divide 20 cm squared by 5 cm:
Length = Area / Width
Length = 20 cm2 / 5 cm
Length = 4 cm
Therefore, the length of the piece of fabric is 4 cm.

To keep up with rising cost a carpenter needs to increase his $30.00 per hour rate by 18% what will be his hour rate ?
Answer:
In order to keep up with rising cost carpenter needs to increase his $30.00 per hour rate to 35.40 $.
Explanation:
To keep up with rising cost a carpenter needs to increase his $30.00 per hour rate by 18%.
So hour rate of carpenter = 30.00 $
Rate of increase = 18 % = 0.18
New hour rate = Initial hour rate + Rate of increase x Initial hour rate
= 30 + 0.18 x 30 = 30 + 5.4 = 35.40 $
So in order to keep up with rising cost carpenter needs to increase his $30.00 per hour rate to 35.40 $.
The carpenter's new hourly rate after an 18% increase on his current rate of $30.00 will be $35.40 per hour.
To calculate the new hourly rate with an 18% increase, first find 18% of the carpenter's current $30.00 per hour rate. The formula for calculating the percentage increase is:
Percentage increase in wage = (Current hourly rate) x (Percentage increase) / 100
In this case, the calculation would be: $30.00 x 18% / 100 = $5.40.
Next, add this increase to the current rate to find the new rate:
New hourly rate = Current hourly rate + Increase in wage
Applying the values:
New hourly rate = $30.00 + $5.40 = $35.40 per hour.
So, the carpenter needs to charge $35.40 per hour to achieve an 18% increase in his rate.

Given a population with mu = 64 and sigma = 25, if one draws samples of size l55, the sample means will have a distribution which is approximately normal with:
Final answer:
The sampling distribution of the sample mean will be approximately normally distributed with a mean of 64 and a standard error calculated by dividing the population standard deviation (25) by the square root of the sample size (155).
Explanation:
The student's question involves the concept of the sampling distribution of the sample mean. Given a population with a mean (μ) of 64 and a standard deviation (σ) of 25, and drawing samples of size 155, the sampling distribution of the sample mean will have a mean equal to the population mean, which is 64. The standard deviation of the sampling distribution (σx), known as the standard error, will be the population standard deviation (σ) divided by the square root of the sample size (n), thus σx = 25/ √155. As the sample size is large, according to the central limit theorem, this sampling distribution will be approximately normal.
Therefore, the sampling distribution of the sample mean will be approximately normally distributed with a mean (μx) of 64 and a standard error (σx) which can be calculated as mentioned above.

The sculptures at Mount Rushmore each measure about 60 feet from chin to forehead. For the average person, this distance is 9 inches. The average distance between a person's ears is 6 inches. What is the ratio of a person's chin to forehead distance compared to the distance between his ears?
Answer:
Distance from chin to forehead is 1.5 times the distance between ears.
Step-by-step explanation:
We are told that distance from chin to forehead for the average person is 9 inches and distance between a person's ears is 6 inches. We are supposed to compare the ratio of a person's chin to forehead distance with respect to the distance between his ears.
We can present our given information as: [tex]\frac{9}{6}[/tex]
[tex]\frac{9}{6} =1.5[/tex]
Therefore, distance from chin to forehead is 1.5 times the distance between ears.

{A, B}
{A, B, 1, 2, 3, 4, 5, 6}
{1, 2, 3, 4, 5, 6}
The sample space for spinning a spinner with two sectors labeled A and B, and rolling a number cube, is {A1, A2, A3, A4, A5, A6, B1, B2, B3, B4, B5, B6}.
Explanation:The sample space for the experiment of spinning a spinner with two sectors labeled A and B, and rolling a number cube, can be determined by listing all the possible outcomes. The outcomes will be the combination of all possible results from spinning the spinner (A or B) and rolling the number cube (1, 2, 3, 4, 5, or 6). Therefore, the sample space is {A1, A2, A3, A4, A5, A6, B1, B2, B3, B4, B5, B6}.

Answer:
(1) .20 (2) .40 (3) .12 (4) Less than
Step-by-step explanation:
You have to look at the table. There are 5 columns with 10 rows. 5x10=50
Then simply count the boxes that have the correct number of currency for instance, if they are asking for EXACTLY 1 dime then you rule out the ones that have 2 or 3 dimes and only the count the ones that have a single dime. So you count PDN but you would not count PDD. There are 20 boxes that have a single dime in them. 20 out of the 50 boxes. 20/50=.40 (answer 2)
The estimated probability that exactly two of the three coins Avery randomly picked are nickels is . 20
The estimated probability that exactly one of the three coins Avery randomly picked is a dime is . 40
The estimated probability that all three coins Avery randomly picked are pennies is . 12
The answer to #1 is .20 or 20% and the answer to #2 is .40 or 40%. 20% is less than 40% so...

One wintry week a ski town got 5 1/3 inches of snow. On monday the town got 2 3/4 inches; on tuesday it got 1 1/2 times as much; and on wednesday it got 7/8 inch. How much snow did the town get the rest of the week?
Answer: The amount of snow the town get the rest of the week is given by
[tex]\frac{5}{24}[/tex]
Step-by-step explanation:
[tex]\text{ Total inches of snow town got in a week }=5\frac{1}{3}=\frac{16}{3}[/tex]
[tex]\text{ Amount of snow it is receiving on Monday}=2\frac{3}{4}=\frac{11}{4}\text{ inches }[/tex]

[tex]\text{Amount of snow it is receiving on Wednesday}=\frac{7}{8}\text{ inches }[/tex]
[tex]\text{Amount it is receiving in remaining week is given by}[/tex]
[tex]\frac{16}{3}-(\frac{11}{4}+\frac{3}{2}+\frac{7}{8})\\\\=\frac{16}{3}-\frac{22+12+7}{8}\\\\=\frac{16}{3}-\frac{41}{8}\\\\=\frac{128-125}{8}\\\\=\frac{5}{24}\text{ inches }[/tex]
So, the amount of snow the town get the rest of the week is given by

Bryan paid $19.95 for 2.5 pounds of turkey.What was the price per pound
Final answer:
The price per pound of turkey is $7.98.
Explanation:
To find the price per pound, divide the total cost by the weight. In this case, Bryan paid $19.95 for 2.5 pounds of turkey. So, the price per pound is $19.95 divided by 2.5, which is $7.98 per pound.To calculate the price per pound of turkey that Bryan paid, we divide the total cost by the total weight. Bryan paid $19.95 for 2.5 pounds of turkey.
Divide the total cost by the total weight in pounds.
$19.95 ÷ 2.5 pounds = $7.98 per pound
Thus, the price per pound of turkey that Bryan paid is $7.98.
Tom paid $245.97 for a laptop. This was 3/5 of the original price. What was the original price?
Let us say original price of the laptop was x dollars.
Price paid by Tom for the laptop = $245.97
Now this price paid by tom was 3/5 of the original price.
So we can make an equation using this information as :
[tex]\frac{3}{5}x=245.97[/tex]
So here 3/5 is in multiplication on the left, so dividing it on the right side we have:
x=409.95
So the original price of the laptop was $409.95
Answer: The original price of the laptop was 409.95 dollars.
Answer:
$409.95

the question in English
Mateo will reproduce a photo measuring 5 cm per side on a scale of 3/4
How much will the square side of the copy measure?
Will the size of the copy be larger or smaller than the original?
we know that
the scale factor is equal to [tex]\frac{3}{4}[/tex]
Let
x----------> the original length side
y--------> the copy length side
[tex]y=\frac{3}{4}*x[/tex]
we have that
[tex]x=5\ cm[/tex]
substitute the values
[tex]y=\frac{3}{4}*5=3.75\ cm[/tex]
therefore
the answer Part a) is
the length side of the copy measure is [tex]3.75\ cm[/tex]
Part b)
we know that
the size of the original photo is------> [tex]5*5=25\ cm^{2}[/tex]
the size of the copy is------> [tex]3.75*3.75=14.06\ cm^{2}[/tex]
so
