Final answer:
The percent error in Clara's estimate of the hiking trail length is calculated using the difference between actual and estimated lengths, resulting in an 8.0% error. Option B is correct.
Explanation:
To calculate the percent error in Clara's estimate of the hiking trail's length, we use the formula: percent error = (|Actual length - Estimated length| / Actual length) × 100. Clara estimated the length to be 5.75 km, while the actual length is 6.25 km.
First, calculate the absolute difference between the actual and estimated lengths: |6.25 km - 5.75 km| = 0.5 km.
Then, divide this difference by the actual length: 0.5 km / 6.25 km = 0.08.
Finally, convert this to a percentage by multiplying by 100: 0.08 × 100 = 8.0%.
Therefore, the percent error in Clara's estimate is 8.0%, making option B the correct answer.

Complete the equation of the line whose slope is -2, and y-intercept is (0,3)
Answer:
y=-2x+3
Step-by-step explanation:
Given the slope intercept form of the general equation of a line below:
y=mx+c,
m is the gradient/slope
c is the intercept on the y-axis.
From the given information:
m=-2 and c=3
Therefore substituting into y=mx+c
The equation is y=-2x+3

A pencil Company used 60 grams of rubber to make 10 pencils how many pencils can be made with 50 grams of rubber
with 50 grams of rubber, you can make approximately 8 pencils.
To solve this problem, we need to set up a proportion to find out how many pencils can be made with 50 grams of rubber.
Let's set up the proportion using the given information:
[tex]\[\frac{\text{Grams of rubber}}{\text{Number of pencils}} = \frac{60}{10} = \frac{50}{x}\][/tex]
Where:
- 60 grams of rubber is used to make 10 pencils.
- 50 grams of rubber is the amount we have.
- x is the number of pencils we want to find.
Now, let's solve for x:
[tex]\[\frac{60}{10} = \frac{50}{x}\][/tex]
Cross multiplying:
60x = 500
Dividing both sides by 60:
[tex]\[ x = \frac{500}{60} \][/tex]
x = 8.333
Since you can't make a fraction of a pencil, we need to round down to the nearest whole number because you can't make a fraction of a pencil. Therefore, with 50 grams of rubber, you can make approximately 8 pencils.
The probable question maybe:
A pencil Company used 60 grams of rubber to make 10 pencils how many pencils can be made with 50 grams of rubber?

how do i find the unit cost of $12 for 4 yd2
To find the unit cost of $12 for 4 yd2, divide the total cost by the number of square yards, resulting in a unit cost of $3 per yd2.
Explanation:To find the unit cost of $12 for 4 yd2, you should divide the total cost by the number of units. In this case, you divide $12 by 4 yd2 to find the cost per square yard. This gives you a unit cost of $3 per yd2.
Here's the step-by-step calculation:
Write down the total cost and the total area: $12 for 4 yd2.Divide the total cost by the total area to find the unit cost: $12 ÷ 4 yd2 = $3 per yd2.This is a simple division problem that involves unit conversion and understanding fractions. When you perform the division, the units of yd2 remain, indicating the cost is per square yard.
Final answer:
To find the unit cost of $12 for 4 yd2, divide the total cost by the number of square yards, which results in $3 per square yard.
Explanation:
To find the unit cost per square yard when given a total cost for a certain number of square yards, you would divide the total cost by the number of square yards. In this case, the question is asking how to find the unit cost of $12 for 4 yd2.
Using simple division, take the total cost of $12 and divide it by the number of square yards, which is 4. This can be set up as a fraction: $12/4 yd2. When you divide 12 by 4, you get 3. Thus, the unit cost is $3 per yd2.
To understand this better, we can think of the 4 yd2 as a fraction, 4yd2/1, where we have 1 in the denominator. By dividing the total cost by the number of square yards, we are finding the price per single unit of area. Division is the mathematical operation used here, and after dividing, we find that each square yard costs $3.

2. A pool company is trying out several new drains. Drain A empties a pool at a rate of 2 gal/min. Drain B empties a pool at a rate of 5 gal/min. One pool has 108 gal of water in it. Write an equation for each drain that shows the amount of time it takes to empty the pool. Then solve each equation showing your work.
Answer:
Drain A [tex]54\ min[/tex]
Drain B [tex]21.6\ min[/tex]
Step-by-step explanation:
Let
x------> the time in minutes
y-----> the volume of the pool in gallons
we know that
The equation that represent the situation is equal to
[tex]y=mx[/tex]
solve for x
[tex]x=y/m[/tex]
Drain A
[tex]x=y/m[/tex]
In this case we have
[tex]m=2\frac{gal}{min}[/tex]
[tex]y=108\ gal[/tex]
substitute
[tex]x=108/2=54\ min[/tex]
Drain B
[tex]x=y/m[/tex]
In this case we have
[tex]m=5\frac{gal}{min}[/tex]
[tex]y=108\ gal[/tex]
substitute
[tex]x=108/5=21.6\ min[/tex]
what is 1/8 converted to percent
To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. If we want to write [tex]\frac{1}{8}[/tex] as a percent, we need to find a fraction equivalent to [tex]\frac{1}{8}[/tex] that has a 100 in the denominator. We can do this by setting up a proportion.
[tex]\frac{1}{8}[/tex] = [tex]\frac{n}{100}[/tex]
Now, we can use cross products to find the missing value.
8n = 100
÷8 ÷8 ← divide by 8 on both sides
n = 12.5
Therefore, [tex]\frac{1}{8}[/tex] is equal to [tex]\frac{12.5}{100}[/tex] or 12.5%.

A football team receives the ball on their own 10 yard line. They make a gain of 15 yards in the first play. What yard line is the ball on?
Final answer:
The football team starts at their own 10 yard line, and after a gain of 15 yards, the ball is on the 25 yard line.
Explanation:
The question is about calculating the new position of a football on the field after a team makes a gain. Initially, the football team starts with the ball on their own 10 yard line. After making a gain of 15 yards in the first play, we can determine the new yard line position by simply adding the gain to the starting position.
Step-by-Step Calculation:
Starting yard line: 10 yards.
Gain made: 15 yards.
Calculate the new yard line position: Starting yard line + Gain made = 10 yards + 15 yards = 25 yards.
Therefore, after the gain, the ball is on the 25-yard line.
