in an examination 40% students passed in math only, 30% passed in Science only, and 10% students failed in both the subjects .if 400 students passed in Science find the total number of students by drawing a Venn diagram.
Answers
Answer:
40% of the student is 160
30% of the students is 120
10% of the students is 40
the remain is ___
160 + 120 + 40= 320
400 -320 = 80
meaning 160 students passes only math (40%). 120 students passed on science (30%). 40 students fail both subjects (10%) and 80 students passes both subjects (20%)
Graph the function f(x)=−14x−2.
Use the line tool and select two points to graph.
Answers
Answer:
You should do this on your own but if you consider the way I graph it, the slope should be going downwards and in the middle of the graph, the y-intercept should be two units down. Each unit for the x line should be 14 units apart as stated in the function.

Interpretation of axes and scales:
The horizontal axis (x-axis): There is time in seconds on the horizontal axis
Scale: 1 unit in the x-axis = 1 second
The vertical axis (y-axis): There is the distance in feet which is the height of the elevator from the ground on the horizontal axis
Scale: 1 unit in the y-axis = 20 feet
Interpretation of the origin:
The coordinate is represented by the point (0,0) in the graph. This means at time = 0 the height of the elevator =0, i.e the elevator is on the ground at the starting time.

If Roger ran 5 miles in 150 minutes, Ryan ran 10 miles in 300 miles, and Rick ran 5 miles in 2 and ½ hours, who had the best rate of running(fastest time)?
Answers
Answer:
All three have same rate of running.
Step-by-step explanation:
Given that:
Distance covered by Roger = 150 minutes
Time taken by Roger = 5 miles
Distance covered by Ryan = 300 minutes
Time taken by Ryan = 10 miles
Distance covered by Rick = 2[tex]\frac{1}{2}[/tex] hours
Time taken by Rick = 2 miles
To find:
Who has the fastest rate of running?
Solution:
First of all, we need to convert the time in hours and then we need to apply the formula for relation between Speed, time and distance.
Then we can compare the Speed.
60 minutes = 1 hour
150 minutes = [tex]\frac{1}{60} \times 150 = 2.5\ hours[/tex]
300 minutes = 5 hours
Formula for Speed:
[tex]Speed = \dfrac{Distance}{Time}[/tex]
Rate of running (speed) of Roger = [tex]\frac{5}{2.5}[/tex] = 2 miles/hr
Rate of running (speed) of Ryan = [tex]\frac{10}{5}[/tex] = 2 miles/hr
Rate of running (speed) of Rick = [tex]\frac{5}{2.5}[/tex] = 2 miles/hr
Therefore, All three have same rate of running.

Answers
Answer: Choice C) [tex]\frac{\sin(23)}{6.2} = \frac{\sin(85)}{b}[/tex]
=========================================================
Explanation:
The angle opposite side b is 85 degrees. So we'll involve either the fraction [tex]\frac{\sin(85)}{b}[/tex] or [tex]\frac{b}{\sin(85)}[/tex]. In this case, we will use the first fraction. This is due to all of the answer choices having sine on top.
The other fraction must have sine on top as well.
The known side is AB = 6.2; the opposite angle is C = 23 which you find by solving A+B+C = 180 and plugging in A = 72 and B = 85.
So the other fraction we'll use is [tex]\frac{\sin(23)}{6.2}[/tex]
Overall, the proportion we can set up is
[tex]\frac{\sin(23)}{6.2} = \frac{\sin(85)}{b}[/tex]
which points to choice C as the final answer.

Answers
Answer:
Hope it helps) and HAPPY NEW YEAR MY DEAR
Step-by-step explanation:
Let A be the number of cards Alan has
B be the number of cards Bill has
C be the number of cards Calvin has
Alan had 11 less than 2 1/2 times the number of cards bill has.
is 2.5
Alan is 2.5 of bill has minus 11
A=2.5B -11
Calvin has 1 more than 1 1/2 times the number of cards bill has.
is 1.5
Calvin is 1.5 of bill has plus 1
C=1.5B + 1
Alan and Calvin have the same number of cards
So A=C
WE plug in A and C equations and solve for B
2.5B -11 = 1.5B + 1 (subtract 1.5B on both sides)
1B -11 = 1 (Add 11 on both sides)
B = 12
If Alan and Calvin have the same number of cards, the number bill has is 12
The number of cards Alan and Calvin each have is 19
Total cards = 12 + 19 + 19 = 50
If Alan, bill, and Calvin have all the cards in the deck then the deck has 50 cards.
what is 1x+3y=18 in slope intercept form
Answers
Answer:
y = -x/3 + 6
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesAlgebra I
Standard Form: Ax + By = C
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
Step 1: Define
Standard Form: x + 3y = 18
Step 2: Rewrite
Find slope-intercept form
Subtract x on both sides: 3y = -x + 18Divide 3 on both sides: y = -x/3 + 6Answer:
y=-3x+6
Step-by-step explanation:
slope int. form is y=mx+b
want to get y by itself, so subtract 1x
so you are left with 3y=-1x+18
then divide 3
left with y=-1/3x+6
simplified is y=-3x+6
