Answer:
So if sarah feeds her fish every two days, youd divide each number by 30. So the fish would be fed 15 times and the snake 5 times. Hope you get it correct! Good Luck!
Answer: hello mate!
Sara feeds her fish every 2 days: this means that if we took the 0 in a day that she feed both animals; then the fish gets food on the day 2, on the day 4, on the day 6, etc
And the snake gets food on days 6, 12, 18, etc.
now we want to count the number of days where both animals get food on the same day. Because 6 is a multiple of 2, we can see that every day that the snake is feed, the fish also feed, this is because the minimal common multiple between 2 and 6 is 6.
then we can see that each 6 days Sarah feeds her fish and snake on the same day. Now we need to see the number of times that this event happens in 30 days; we can see this dividing 30 days by 6 days:
30/6 = 5
Then in the span of 30 days, there are 5 times where both animals get food on the same day.
Aldrin and Jan are standing at the edge of a huge field. At 2:00 p.m., Aldrin begins to walk along a straight path at a speed of 3 km/h. Two hours later, Jan takes a straight path at a 608 angle to Aldrin’s path, walking at 5 km/h. At what time the two friends be 13km apart?
Answer: After 2:29 hours both Aldrin and Jan will be 13 km apart from each other.
Time at that instant will be : 4:00 pm + 2.29 hours= 6:29 pm
Step-by-step explanation:
According to the figure:
Ab= c = 13 Km
AC = b = [tex]distance= speed\times time =5\times t[/tex]=5t Km
After two hours the distance covered by the Aldrin say till point D :
[tex]distance=speed\times time=3km/hr\times 2 hrs=6 Km[/tex]
Since, we are interested in determining the time at which Aldrin and Jan both 13 Km apart. For that Aldrin Additional distance covered by the Aldrin from point D to B is :
[tex]distance=speed\times time= 3km/hr\times t=3t Km [/tex]
CB= a = CD+DB= 6+3t
We will apply Laws of cosines:
[tex]C^2=A^2+B^2-2AB\times Cos\theta[/tex]
[tex](13)^2=(6+3t)^2+(5t)^2-2(5t)(6+3t)Cos 60^o[/tex]
[tex]19t^2+6t-133=0[/tex]
On solving the the above equation by quadratic formula we get two values of 't'
1) t = 2.49 hours , 2) t = -2.80 hours
Since,time cannot be in negative so we will ignore the negative value of t
t = 2.49 = 2:29 hours ,(0.49 hour=0.49 × 60 min=29.4 min)
After 2.49 hours after the walking of Jan. Both Aldrin and Jan will be 13 km apart from each other.
Time at that instant will be : 4:00 pm + 2:29 hours= 6:29 hour
A line passes through the points (-10,-5) and (20,10) what is the equation of the line A. y=5x B.Y=2x C.1/2 x Dy=1/5 x
Answer:
C. y = ½x
Step-by-step explanation:
Step 1. Find the slope of the line
The general equation for a straight line is
y = mx + b
The slope m is
m =(y₂ -y₁)/(x₂/x₁)
Your points are (-10, -5) and (20, 10).
m = [10 – (-5)]/[20 – (-10)] Remove inner parentheses
m = (10+5)/(20 + 10)
m = 15/30
m = ½
===============
Step 2. Find the equation of the line
Substitute the point (20, 10) into the general equation.
10 = ½×20 + b
10 = 10 + b
b = 0
The equation of the line is y = ½x.
The graph shows your line passing through your two points with a slope
m = ½ and a y-intercept at (0, 0).
the function y=3.28x converts length from x meters to y feet Im really stuck im not real sure what to do
Step-by-step explanation: So this one can be a little confusing, but I think I can help. You see if 'y'= number of feet and 'x'= number of meters then y=3.28x is a way for you to figure out how many feet are constant to every meter.
Look at it more like, Number of Feet= 3.28 times the number of meters.
If you want to figure out many feet are constant to let's say...2 meters, then you would replace the 'x' variable with 2 and multiply it by 3.28.
It would look something like this:
y=3.28(2)
y= 6.56
Thus, every 1 feet there are 6.56 meters, or 6.56 meters equals 1 foot.
Hope this helps a little, tell me if you need anymore help with this!

A steel rod that is 64 feet long must be cut into three pieces to fabricate the supports for a drill press. The longest piece is 3.09 times the shortest and the middle piece is 1.73 times the shortest. How long is each piece? Round nearest foot.
Answer:
let's x be the shortest piece
the middle piece is 1,73 *x
the longest piece is 3,09 x
then if we sum the 3 pieces we will get the steel rod that is 64 feet long
so x+1,73x+3,09x= 5,82x= 64 then x= 10,99 = 11
the shortest piece is 11 feet
the middle piece is 1,73*11=19,03 feet
The longest piece is: 3,09*11= 33,99= 34 feet

PLS HELP If g(n) varies inversely with n and g(n) = 6 when n = 2, find the value of n when g(n) = 1.5.
Answer:
g(2)=1.5. Which would be three.
Step-by-step explanation:
You would just plug in n=2 into the equation and then divide it out.
The value of n, when g(n) is 1.5, given that g(n), varies inversely with n and equals 6 when n is 2, we first find the constant of variation k = 12 and then divide k by 1.5 to get n = 8.
If g(n) varies inversely with n, the relationship between g(n) and n can be expressed as g(n) = k/n, where k is a constant. When g(n) = 6 and n = 2, we can find the constant k by multiplying 6 and 2 to get k = 12.
To find the value of n when g(n) = 1.5, we can set up the equation 1.5 = k/n. Using our previously found constant k (12), we substitute it into the equation to get 1.5 = 12/n. Solving for n, we multiply both sides of the equation by n and then divide both sides by 1.5 to get n = 12/1.5, which simplifies to n = 8.
What is the length of angle BC?
If you mean side BC (instead of angle BC), then the answer is 22 units.
To get this answer, set the sides AB and AC equal to each other and solve for x
AB = AC
2x - 24 = x - 2
2x-x = -2+24
x = 22
Since BC = x, and x = 22, this means BC is 22 units long.
We have m∠C = m∠B, therefore it's an isosceles triangle.
Therefore we have the equation:
2x - 24 = x - 2 add 24 to both sides
2x = x + 22 subtract x from both sides
x = 22
BC = x

Suppose a railroad rail is 2 kilometers and it expands on a hot day by 19 centimeters in length. Approximately how many meters would the center of the rail rise above the ground?
Answer:
rail rise approximately 0.19 m above the ground
Step-by-step explanation:
as we know that
1m=100cm
and 1cm=[tex]\frac{1}{100}[/tex] m
similarly
19cm=[tex]\frac{19}{100}[/tex]m
19cm=0.19m
rail rise approximately 0.19 m above the ground
The calculated sagitta is approximately 0 meters, considering the very small expansion compared to the original length of the rail.
Assuming the rail forms an arc of a circle with the expansion, the rail's ends remain on the ground, and only the center rises.
Consider the original length of the rail as the chord of the circle, and the expanded length as the arc of the circle. The rise of the rail's center is the sagitta (height) of the arc. The length of the chord (C) is 2000 meters, and the expansion (e) is 0.19 meters (19 centimeters). The length of the arc (A) is C + e, which equals 2000.19 meters.
The formula for the sagitta when the arc is very close to the chord in length is given by:
Sagitta (s) ≈ (e² / (8 * C)) + (C² / (8 * A))
Plugging in the values:
s ≈ (0.19² / (8 * 2000)) + (2000² / (8 * 2000.19))
After calculation:
s ≈ 2.25 × 10⁻³ m + 250 m
s ≈ 250.00225 m
Since we are dealing with a very small expansion relative to the size of the rail, the sagitta (height increase of the center of the rail) is very close to 0 meters.
Your model train is 18 inches long.
It is an exact model of a train that is 72 feet long.
A window on the train is how many times wider than a window on the model?
Answer:
48 times wider
Step-by-step explanation:
Convert length of train to inches:
[tex]72 * 12 = 864[/tex] inches
Divide the length of the train by the length of the model train to find the scale.
so, 864 ÷ 18 = 48
and since the model train is proportional to the train, the window on the train is 48 times wider than the window on the model.
Answer:
48

3 1/2 divided by 2 1/4
To divide mixed numbers like 3 1/2 and 2 1/4, first convert to improper fractions. In this case, 3 1/2 divided by 2 1/4 simplifies to 1 5/9.
Explanation:To solve the problem of 3 1/2 divided by 2 1/4, you need to first convert each mixed number into an improper fraction.
3 1/2 becomes 7/2 and 2 1/4 becomes 9/4, because 3*2 + 1 = 7 (for the first number) and 2*4 + 1 = 9 (for the second number), the numerators of the fractions.
Next, in our division problem, we flip the second fraction (this is the reciprocal), and multiply it with the first. It's the same as multiplying by its inverse to divide fractions.
So, 7/2 divided by 9/4 becomes 7/2*
4/9 which equals 28/18, which can be simplified to 1 10/18 or further simplified to 1 5/9 in mixed number form.

First fourth and tenth terms a(n) = 5 + (n + 1) 1/6
Answer:
a(4) = 5 5/6
a(10) = 6 5/6
Step-by-step explanation:
To find the 4th term, let n =4
a(n) = 5 + (n + 1) 1/6
a(4) = 5 + (4+1) 1/6
=5+5 * 1/6
= 5 + 5/6
= 5 5/6
To find the 10th term, let n =10
a(n) = 5 + (n + 1) 1/6
a(10) = 5 + (10+1) 1/6
=5+11 * 1/6
= 5 + 11/6
= 5 + 1 5/6
= 6 5/6
The regular price of a newly released video game is $32. LeBron buys the video game when its on sale for 30% off the regular price. If sales tax is 10%, how much does LeBron pay for the video game.
Answer:
$24.64
Step-by-step explanation:
30% off is equal to multiplying by 0.7
(32*0.7)*1.1
Sales tax increases the price and so you multiply by 1.1 (equal to increasing 10%)
32*0.7*1.1=24.64
He will pay $24.64 for the game.

= (19/2)b + 15
Question number 2
3/4 (16/64 + 12a) -9a =
= (3/4) * (16/64) + (3/4) * 12a - 9a
= (3 * 16)(4 * 64) + (3/4) * (12/1) * a - 9a
= (3 * 1)(4 * 4) + (3 * 12)/(4 * 1) * a - 9a
= 3/16 + (3 * 3)/(1 * 1) * a - 9a
= 3/16 + 9a - 9a

Determine the slope for the following:
-6x-2y=12
Answer:
New Slope is -3
Step-by-step explanation:
First we will need to simplify the equation to make it easier. so since all numbers are divisible by 2 so instead of -6x-2y=12 the new equation will be -3x-y=6. then you are gonna solve for y and the answer is -y=3x+6. so then you will divide by -1 to make y positive. then Your Final Equation is y=-3x-6
Your new slope is -3
