Eli takes a typing test and types all 180 words in 1 12 hour. He takes the test a second time and types the words in 1 15 hour. Was he faster or slower on the second attempt? Drag and drop the correct word or number into each of the boxes to complete the explanation. Eli typed on his second attempt. He typed words per minute on his first attempt and words per minute on his second attempt.
Step-by-step explanation:
Eli typed faster on his second attempt, 120 words per minute on his first attempt and 150 words per minute on his second attempt.
What is Fraction?A fraction represents a part of a whole.
We need to calculate his typing speed for each attempt.
On his first attempt, Eli typed 180 words in [tex]1\frac{1}{2}[/tex] hours, which is the same as typing 120 words in 1 hour.
Therefore, his typing speed on the first attempt was 120 words per minute.
On his second attempt, Eli typed 180 words in [tex]1\frac{1}{5}[/tex] hour, which is the same as typing 150 words in 1 hour.
Therefore, his typing speed on the second attempt was 150 words per minute.
Comparing the two speeds, we see that Eli was faster on his second attempt, typing 150 words per minute compared to 120 words per minute on his first attempt.
Therefore, Eli typed faster on his second attempt, 120 words per minute on his first attempt and 150 words per minute on his second attempt.

The lenngths of the sides of the triangle are in the extended ratio 8:9:10. The primeter of the triangle is 108 cm.What are the lengths of the sides?
The lengths of the sides of the triangle in cm are____?
Please help I really need this!
Answer:
Side known in ratio as 8: 32
Side known in ratio as 9: 36
Side known in ration as 10: 40
Step-by-step explanation:
We can add all the numbers in the ration to form the sum of all the sides, or also equal to perimeter. 8+9+10 equals 27.
So we can write 27x=108
x=4. Multiply 4 to 8, then 9, then 10. You get 32, 36, 40

Write the equation of the line that goes through (-3.9, -1.4) and is PERPENDICULAR to 6x + 2y = 9
9514 1404 393
Answer:
10x -30y = 3
Step-by-step explanation:
In general form, you can start by swapping the x- and y-coefficients, negating one of them. To find the new constant for the equation, substitute the values for the given point
2x -6y = 2(-3.9) -6(-1.4)
2x -6y = 0.6
Multiplying by 5 will make the numbers be integers, so will put the equation in standard form.
10x -30y = 3

Graph: y-3=1/2(x+2)
Answer:
Step-by-step explanation:
First you need to find the Slope Intercept form or find the point and slope.
The point is: (-2,3)
and the slope is: 1/2
y - 3 = 1/2(x + 2)
y - 3 = 1/2x + 1
y = 1/2x + 1 + 3
y = 1/2x + 4
Slope intercept form: y = 1/2x + 4

A scale drawing of an airplane is shown with a scale of 24 feet = 1 centimeter. What is the length of the actual plane?
Answer:
144 feet
Step-by-step explanation:
I forgot how it is that answer but I am sure that is the answer.
Pls Show your work on the slope
Answer:
1) slope = 1/5
x - intercept = (10, 0)
y - intercept = (0,-2)
2) use the method I used for number one to do number 2.
Step-by-step explanation:
slope = rise/run = y2-y1/x2-x1
1)
use any 2 points on a line. Chose one y-value which is y2 and the corresponding x-coordinate is x2. In the other coordinates, the y-value is y1 and the x-value is x1. Let's use points:
(-10, -4)
(-5, -3)
y2 = -3, which means:
y1 = -4
x1 = -10
x2 = -5
plug in the values:
-3-(-4)/-5-(-10)
=1/5
X - intercept is when y = 0. Plug in 0 for y when you see it.
x-0 = 10
x=10
x-intercept = (10,0)
Same for y intercept, except x = 0 this time.
0-5y=10
-5y=10
y=-2
y-intercept = (0,-2)

3. Determine whether these two lines are parallel, perpendicular, or neither. 1 point
8x + y = 7, 4x + 3y = 12 *
parallel,
perpendicular or
neither
Answer:
The two lines are neither
Step-by-step explanation:
Parallel lines have equal slopes and different y-interceptsPerpendicular lines have a product of their slopes = -1The slope of a line whose equation is ax + by = c is m = [tex]\frac{-a}{b}[/tex]∵ The equations of the lines are
8x + y = 7 ⇒ 1st4x + 3y = 12 ⇒ 2nd∵ In the 1st equation a = 8 and b = 1
∴ m1 = [tex]\frac{-8}{1}[/tex] = -8
∴ The slope of the 1st line is -8
∵ In the 2nd equation a = 4 and b = 3
∴ m2 = [tex]\frac{-4}{3}[/tex]
∴ The slope of the 2nd line is [tex]\frac{-4}{3}[/tex]
→ By using the facts above
∵ m1 ≠ m2
∴ The two lines are not parallel
∵ m1 × m2 = -8 × [tex]\frac{-4}{3}[/tex] = [tex]\frac{32}{3}[/tex]
∴ m1 × m2 ≠ -1
∴ The two lines are not perpendicular
∴ The two lines are neither parallel nor perpendicular

What is the probability of being born in May or on the 30th of any month?
Answer: 41/365
Step-by-step explanation:
The probability of being born in May is 31/365 (May has 31 days and there are 365 days in a year).
The probability of being born on the 30th of the month is 11/365 (11 months have at least 30 days). However, since we have included May 30 in our MAy probability, we need to use the probability of 10/365.
Add the two probabilities together, and the probability of being born in May or on the 30th is 31/365 + 10/365 = 41/365.
