Answer:
459
Step-by-step explanation:
Since to find out mile to kilometer you divide the mile by 1.609 would equal 458.66304 and rounding it to the nearest whole kilometer is 459 there is you answer.
The distance between Lowell and Shelby is approximately 460 kilometres.
Given that information:
1 km = 0.62 miles
Also given the distance between Lowell and Shelby is 285 miles.
To convert miles to kilometres, use the conversion factor:
1 mile = 1.60934 kilometres
Now calculate the distance in kilometres as follows:
Distance in kilometres = 285 miles × 1.60934 km/mile
Distance in kilometres ≈ 459.7 kilometres.
Now, round the answer to the nearest whole kilometre as follows:
Distance in kilometres ≈ 460 kilometres.
Hence, the distance between Lowell and Shelby is approximately 460 kilometres.

Answer:
4/15
Step-by-step explanation:
They have baked 1/3 + 2/5. To add you need common denominators.
1/3 = 5/15, 2/5 = 6/15
5/15 + 6/15 = 11/15. This is what they baked.
To find what is left, we need to subtract from 1. 1 = 15/15
15/15 - 11/15 = 4/15

Step-by-step explanation:
What is the equation of the line that goes through the points (1,1) and 3,-3)
Answer:
y = -2x + 3
Step-by-step explanation:
[]Let us write an equation in slope-intercept form.
-> See attached
-> Our equation will start out as y = x
[] The slope can be found by taking the change in y divided by the change in x
-> [tex]\frac{-3-1}{3-1}=\frac{-4}{2}=\frac{-2}{1}=-2[/tex]
-> Now our equation is y = -2x
[] The y-intercept, or b, can be found by plugging a point given to us into the equation we have so far.
-> y = -2x + b
(1) = -2(1) + b
1 = -2 + b
3 = b
-> Now our equation is y = -2x + 3, which is our final answer.

Answer:
y = -2x +3
Step-by-step explanation:
coordinates given (1,1) and (3,-3)
How to find equation? first find slope.
slope formula:
(y2-y1)/(x2-x1)
using this formula:
(-3-1)/(3-1)
-4/2
-2 ........this is slope also refereed as (m) in short form.
Use the formula:
y - y1 = m( x - x1)
using the formula:
y - 1 = -2( x - 1)
y -1 = -2x + 2
y = -2x +3

Is (-5,2) a solution to this system of equations?
x=-5
y=2x+10
Answer: No, it's not the solution
Explanation:
Let's plug x = -5 into the second equation
y = 2x+10
y = 2(-5)+10
y = -10+10
y = 0
This shows that (-5,0) is the actual solution, instead of (-5,2)
The diagram shows three straight lines work out the size of angles a, b and c.
Answer:
a = 21°
b = 70°
c = 89°
Step-by-step explanation:
a = 21° as vertically opposite angles are equal
to work out b:
angles on a straight line add up to 180
b + 110 = 180
b = 180 - 110
b = 70°
to work out c:
the sum of angles in a triangle add up to 180
we have a and b
21 + 70 + c = 180
91 + c = 180
c = 180 - 91
c = 89°

Is g = 4 a solution to the inequality below? 8 − g > 4
Answer:
Given, 3x−2<2x+1
⇒3x−2x<1+2
⇒x<3orx∈(−∞,3)
The lines y=3x−2 and y=2x+1 both will intersect at x=3
Clearly, the dark line shows the solution of 3x−2<2x+1.
Answer:
No
Step-by-step explanation:
If you input g = 4 into the inequality, you have
8 - 4 > 4
4 > 4
4 is NOT greater than 4
To be correct, the inequality would have to read:
8 - g ≥ 4
This would be correct because now it reads
4 ≥ 4
4 is greater than OR equal to four
What is the value of x ? ( x= ??)
A x = 121
B x = 10
C x - 59
D x = 20
Answer:
The variable x is equal to 10 degrees.
Step-by-step explanation:
A triangle's angles, in total, must equal 180 degrees.
71 + 50 + (6x-1) = 180
71 +50 = 121
121 + (6x-1) = 180
6x - 1 = 59
6x = 60
x = 10

James and Sarah went out to lunch. The price of lunch for both of them was $80. They tipped their server 20% of that amount. How much did each person pay if they shared the price of lunch and the tip equally? Each person paid $
Answer:
28 Dollars
Step-by-step explanation:
80 diveded by 2 is 40
20 percent of 40 is 8
there for each should have tipped 28
Answer:
total tipped = 20% × $80
= $16
total lunch price = $80 - $16
= $64
amount each person pay for tipped
= $16 ÷ 2
= $8
amount each person pay for lunch
= $64 ÷ 2
= $32
total each person pay for lunch and tipped
= $8 + $32
= $40
At the first pep rally of the season, the football team and the volleyball team were presented to the student body. During the pep rally, up to 11 players talked to the crowd. Football players talked about 17 seconds each and volleyball players talked about 28 seconds each.
If the players only had a total of 242 seconds (4.03 minutes), which system of inequalities could be used to determine the number of football players (f) and volleyball player! (v) that could talk to the student body?
A. f+ y< 11 17f+ 287< 242
B. ftv< 11 17y + 28% < 242
C. f+ v< 11 176+ 28v< 242
D. ftv< 11 17v+28f< 242
Answer:
A. f + y ≤ 11
17f + 287 ≤ 242
Step-by-step explanation:
[] Let f be football players and v be volleyball players.
-> The total time must be less than or equal to 242 seconds.
-> If football players talked for 17 seconds, we can write it as 17f.
-> If volleyball players talked for 28 seconds, we can write it as 28v.
[] Coming back to the first point I made, the total time must be less than or equal to 242 seconds.
-> 17f + 28v ≤ 242
[] This is going to be a part of our system of inequalities
-> Because of this, we rule out the following options.
B & D - the football players talk for 17 seconds, not the volleyball players
C - not less than or equal too, only less than
[] This leaves us with the option of A.
-> The first part of it also works. If 11 players can talk to the crowd, then the total of f and v must be equal too or less than 11.

Hi i need help with question number 1
Given: f(x) = 5x* - 3x² + 6x + 2. Find f(-2).
Answer:
f(-2) =-32
Step-by-step explanation:
f(x) = 5x* - 3x² + 6x + 2. f(-2)
f(-2) = 5(-2) - 3([tex]-2^{2}[/tex]) + 6(-2) + 2
f(-2) = -10 - 3(4) -12 + 2
f(-2) = -10 - 12 -12 + 2
f(-2) = (-10 - 12 -12) + 2
f(-2) = (-10 -24) + 2
f(-2) = (-34) + 2
f(-2) =-32
Hope that helps!

f(-2) = 5(-2) - 3(-2)² + 6(-2) + 2
Note :positive × negative = negative(-x)² = -x × (-x)negative × negative = positive[tex]f( - 2) = - 10 - 3.4 + ( - 12) + 2[/tex]

Becky tells her friend about the Rule of 72 and her friend immediately
tries it out with her own example. Becky doesn't see all of her friend's
math but does see f(4) = 18 written on her friend's paper.
a. What do you know about the friend's investment based on this?
b. Is the friend's math correct based on the rule of 72?
Answer:
a. the investment earns 4%
b. yes
Step-by-step explanation:
The "rule of 72" says that an investment earning compound interest at x% will double in value after 72/x years. That is, ...
f(x) = 72/x
__
a.We interpret f(4) to mean Becky's friend is interested in the doubling time for an investment that earns 4% interest.
__
b.Using the above formula, ...
f(4) = 72/4 = 18
The friend's math is correct.
