Answer:
It lets me add one now! The answer is 3.75
Step-by-step explanation:
1/4 of a unit is 25%
When converted to a decimal, 25% = .25
4 - .25 = 3.75
We can check this by using reversive property:
4 - .25 = 3.75
3.75 + .25 = 4

Which equation does the graph below represent?
A coordinate grid is shown. The x-axis values are from negative 5 to positive 5 in increments of 1 for each grid line, and the y-axis values are from negative 10 to positive 10 in increments of 2 for each grid line. A line is shown passing through the ordered pairs negative 4, 8 and 0, 0 and 4, negative 8.
y = −2x
y = fraction negative 1 over 2x
y = 2x
y = fraction 1 over 2x
Answer:
y = -2
Step-by-step explanation:
The graph passes through (0,0) and (-1,2).
The equation of a line passing through the origin is of the form,
y = mx
We now substitute (-1,2) to obtain,
2 = -m
This implies that,
m = -2
The equation is
y = -2

19) If manish saves 40% percent of his monthly income and he spends Rs. 15,000 every month, find his monthly income.
Answer:
Rs 25000
Step-by-step explanation:
Saves 40%
Spends 60%
Spending 60% = 15000
If 60% = 15000
Then divide it by 6 to get 10%
10% = 15000 ÷ 6
10% = 2500
100% = 25000

Which is the correct label of the parallel lines? Parallel lines a and b are shown. Points A and B lie on line a while points C and D lie on line b. The letters a and b are separated by two vertical lines. There is a horizontal line with arrows on either end over the letters A A. There is another horizontal line with arrows on either end over the letters C B. A vertical line with a horizontal line intersecting it at the bottom separates the two pairs. There is a horizontal line over the letter A with one arrow on the right end. There is a horizontal line over the letter B with one arrow on the right end. The letters are separated by two vertical lines. There is a horizontal line with arrows on either end over the letters A B. There is another horizontal line with arrows on either end over the letters C D. A vertical line with a horizontal line intersecting it at the bottom separates the two pairs.
Answer:
b
Step-by-step explanation:
right
a || b will be the correct label for the parallel line so option (A) will be correct.
What are parallel lines?Two lines in the same plane that are equally spaced apart and never cross each other are said two lines in the same plane that are equally spaced apart and never cross each other to be parallel lines.
Parallel lines are those lines in which slopes are the same and the distance between them remains constant.
Given the two lines a and b as parallel.
If we want to show any two lines as parallel then we use |the | sign in between them.
Now in the given figure, A B C D are points on lines a and b so they will not be used to show parallel lines.
Hence "a || b will be the correct label for the parallel line".

In 60 seconds , Darrell walks 90
90
meters. Describe the unit rate at he wall
Answer:
1.5 sec by meters
Step-by-step explanation:
90 meters/60 sec=1.5
Darrel walks at a unit rate of 1.5 m/sec.
What is speed?Speed is defined as the rate of change of position in unit time.
Mathematically,
Speed = Distance/Time
Now it is given that,
Distance in walk by Darrell = 90 meters
Time taken by Darell to walk 90 meters = 60 seconds
Therefore Speed i.e unit rate of walk is given as,
Unit rate of walk = Distance in walk by Darrell / Time taken by Darell to walk 90 meters
⇒ Unit rate of walk = 90/60 m/sec
⇒ Unit rate of walk = 3/2 m/sec
⇒ Unit rate of walk = 1.5 m/sec
Thus, Darrel walk at a unit rate of 1.5 m/sec.

45 is what percent of 60 as an equation
Answer:
75% of 60 = 45
Step-by-step explanation:
In order to find the answer to this question you need to divide the percentage of the number by one-hundred and then divide that number by the number the number you are trying to find the percentage of.
60/x=100/75
(60/x)*x=(100/75)*x
60=1.33333333333*x
(1.33333333333) to get x
60/1.33333333333=x
45=x
x=45
75% of 60 = 45

A psychologist plans an experiment in which subjects draw an object based on a verbal description. For each trial, one person draws, one reads the description, and one records how long it takes to get a successful drawing.
From a group of 8 people, in how many ways can the psychologist select a person to draw, a person to read, and a person to record time?
Answer:
336
Step-by-step explanation:

The correct answer is 336.
How many ways can the psychologist select a person to draw, a person to read, and a person to record time?
By using the arrangement calculation formula:
⇒ [tex]A^{3}[/tex][tex]^{8}[/tex]
⇒ 8 × 7 × 6
⇒ 336
The correct answer is 336.
How do you calculate an arrangement?Remember that combinations are a way to calculate the total outcomes of an event where the order of the outcomes does not matter. To calculate combinations, we will use the formula NCR = n! / r! * (n - r)!, where n represents the number of items, and r represents the number of items being chosen at a time.

Please give me the crown.
~Happy Helper~
Based on the temperature change and the amount of time it did so, the average change in temperature per hour is -3.5°F.
The average change in temperature per hour can be found by:
= Temperature change / Number of hours
Solving would give:
= -23.8 / 6.8
= -3.5°F
We can therefore conclude that in every hour of this cold day, the temperature changed by an average of -3.5°F.

Given f(x) = x^2 – 5x + k, and the remainder when f(x) is
divided by x - 7 is 34, then what is the value of k?
Step-by-step explanation:
f(7) = 34
7² -5(7) +k = 34
49-35+k =34
14+k = 34
k = 34-14
k = 20
__________
[tex] \: [/tex]
f(x) = x² - 5x + k
f(7) = 34
Soo :
f(7) = 34
(7)² - 5(7) + k = 34
49 - 35 + k = 34
14 + k = 34
k = 34 - 14
k = 20✔

Find the difference (7-3t) - 5(-1.6t + 5)
Answer:
5t - 18
Step-by-step explanation:
STEP 1: Simplify 8/5
equation at end- 8 (7 - 3t) - (5 • ((0 - (— • t)) + 5)) 5
STEP 2: 2.1 Adding a whole to a fraction
Rewrite the whole as a fraction using 5 as the denominator :
5 5 • 5
5 = — = —————
1 5
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
\2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
-8t + 5 • 5 25 - 8t
——————————— = ———————
EQUATION AT END: (25 - 8t)
(7 - 3t) - (5 • —————————)
