All factors of 40, 41, 3526, and 1001.
Answer:
Step-by-step explanation:
factors for
40=1,2,4,5,8,10,20,40
41=1,41 prime
3526=1,2,41,43,82,86,1763,3526
1001=1,7,11,13,77,91,143,1001
Answer:
Factors Of 40 in Pairs
1 × 40 = 40.
2 × 20 = 40.
4 × 10 = 40.
5 × 8 = 40. Therefore, the factors in pairs are (1, 40), (2, 20), (4, 10) and (5, 8).
Factors of 41: 1, 41
Factors of 3526 =1, 2, 41, 43, 82, 86, 1763, 3526.
1, 7, 11, 13, 77, 91, 143, and 1001. Factors of 1001 include negative numbers.
Step-by-step explanation:
Which proportion could be used to find the length of side b?
6
720
859
A
6.2
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.

Answer:
75 + 64 = 139
Step-by-step explanation:
The measure of the exterior angle is 139
Answer:
2= 139
Step-by-step explanation:
A triangle is 180 degrees.
64+75= 139
180-139=41
A line is also 180 degrees
180- 41= 139

Step-by-step explanation:
You throw a ball into the air from a height of 5.5 feet with an
initial vertical velocity of 40 feet per second. Use the vertical
motion model, h = -16t2 + vt +s, where v is the initial
velocity in feet per second and s is the height in feet, to
calculate the maximum height of the ball. Round your answer
to the nearest tenth if necessary.
Maximum height: feet
Answer:
30.5 feet
Step-by-step explanation:
Alan, Bill, and Calvin are playing a game with collectible cards. At the moment, Alan has 11 less than 2 and a half times the number of cards Bill has. Calvin has 1 more than 1 and a half times the number of cards Bill has. If Calvin and Alan have the same number of cards, the number of cards Bill has is
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.
1. Find the vector represented by the directed line segment drawn from the point (3,5) to point B(-1,2). Also, find it's magnitude.
Your Answer:
Answer:
Magnitude is 5
Step-by-step explanation:
Using the formula for calculating the distance between two points expressed as:
D = √(x2-x1)²+(y2-y1)²
Given the coordinates (3,5) and (-1,2)
D = √(2-5)²+(-1-3)²
D = √(-3)²+(-4)²
D = √9+16
D = √25
D = 5
Hence the magnitude is 5

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.
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%)
The sum of two numbers is 17 and the difference is 5

This venn diagram represents the science subjects studied by students what is the probability that a student,chosen at random,studies physics and chemistry or both ?
Answer:
Step-by-step explanation:
Looking at the Venn diagram :
The total number of students surveyed is 7+5+8+6+2+4+3+6 = 41
The number of students that studies physics is = 14
The number of students that studies chemistry is = 21
Probability = number of favorable outcomes / total number of outcomes
Therefore the probability that a student chosen at random studies physics and chemistry or both is 35/41 = 0.85

1) Graph by making a
table.
y=1/2x+2
Answer:
Below.
Step-by-step explanation:
You can use any 4 x values, so we could have:
- 2 0 2 4
Now find the corresponding y values by substitution in the equation:
For x = -2, y = 1/2 *-2 + 2 = 1.
For x = 0, y = 1/2 * 0 + 2 = 2.
For x = 2 , y = 1/2* 2 + 2 = 3.
For x = 4 , y = 1/2 * 4 + 2 = 4.
So the table is:
-2 0 2 4
1 2 3 4
You then plot the points (-2, 1), (0, 2), (2, 3) AND (4, 4) on the grid and draw a line through them The graph will be a straight line.
Write the equation that represents the line shown.
Answer:
[tex]y = - x + 2[/tex]
Step-by-step explanation:
[tex]y = mx + b[/tex]
[tex]y = \frac{ - 2}{2} x + 2[/tex]
[tex]y = - x + 2[/tex]

THANK YOU ALL! <3 (´▽`ʃ♡ƪ)
Answer:
x=2.5 for the second question!
x= -8.3 repeating for the 5th question
Step-by-step explanation:
Answer:
1. x = 9
2. x = 5/2
3. x = -64
4. x = -20
5. x = -5
6. x = 19
7. x = -6
Step-by-step explanation:
1.
-3x + 9 = -18
-3x = -27
x = 9
2.
2x - 14 = -9
2x = 5
x = 5/2
3.
x/2 + 8 = -24
x/2 = -32
x = -64
4.
-2.5x - 10 = 40
-2.5x = 50
x = -20
5.
-6x - 10 = 20
-6x = 30
x = -5
6.
50 = 2x + 12
38 = 2x
19 = x
x = 19
7.
x/2 - 7 = -10
x/2 = -3
x = -6

i need help asappppp
Answer:
∠1 = 40
Step-by-step explanation:
So due to the alternate interior angles theorem, angle 1 and angle 2 equal each other so:
2x + 20 = 3x + 10
subtract 2x from both sides
20 = x + 10
subtract 10 from both sides
10 = x
Now input 10 into the equation
2(10) + 20
20 + 20
40
