.2 of an hour is .2 * 60 min = 12 min
120 min / 10 times = 12 min per trip
The train takes 12 minutes to go around the museum once.
What is multiplication?A mathematical arithmetic operation is multiplication. Moreover, it is the practice of repeatedly adding the same expression kinds.
Example: 2 x 3 means that 2 is multiplied by 3 or that 3 is multiplied by 2 times.
A toy train that travels the length of a train museum is present. In two hours, the train travels roughly ten times.
The error in the student's work is converting 0.2 hours to 20 minutes. 0.2 hours is equal to 12 minutes, not 20 minutes.
To correct the student's work, we can multiply 0.2 by 60 to convert it to minutes:
0.2 hours × 60 minutes/hour = 12 minutes
Therefore, it takes 12 minutes for the train to go around the museum 1 time.

Answer:
1.25
Step-by-step explanation:
There is an invisible 1 whenever you add x, y, w, whatever. So when you add w + .25w you are really adding 1w + .25w. Because these are like terms, they go together and combined 1+.25 is 1.25. I hope this helps.
Huy borrowed $4500 from a bank at a rate of 5% per year compound interest. He paid back the money and interest at the end of 2 years.
How much interest did he pay?
Answer:
Step-by-step explanation:
FV = PV ( 1 + i)^n i = decimal interest per period(year) n = periods(years)
FV = future value PV = present value (deposit or loan amount)
FV = 4500 ( 1 + .05)^2
FV = 4500(1.05)^2 = 4961.25 subtract the orginal deposit which means 461.25 interest paid at 2 yrs

What is the measure of angle y? 20
Step-by-step explanation:
as per the rules of intersecting lines, the angles between the lines must be the same on both sides of the lines. the just "mirror" (so, left becomes right, and right becomes left).
and since the basic grid is created with perpendicular lines (standing at 90° at each other), we are dealing in the top right and bottom left quarters with 2 angles that together add up to 90°.
these are called complementary angles.
so, in the top right quarter we have a 52° angle, and the other one must be
90 - 52 = 38°
as mentioned, the angles in the bottom left quarter must be the same but are mirrored, so,
y = 38°
The measure of angle ∠y = 38°
What are the angles formed by 2 intersecting lines?Two straight lines that intersect at the same location are said to be intersecting lines. The junction point is the place where two intersecting lines meet. Four angles are created when two lines cross. The four angles added together always equal 360 degrees.
Perpendicular lines are two straight lines that intersect and form right angles. When two perpendicular lines intersect, they form four right angles.
When lines intersect, two angle relationships are formed:
Opposite angles are congruent
Adjacent angles are supplementary
Given data ,
Let the first line be A
Let the second line be B
Now , the lines A and B intersect at the point O perpendicular to each other
And , The angles formed are = 90°
Let the measure of m∠A = 52°
Now , the measure of m∠y = 90° - 52°
The measure of angle m∠y = 38°
Hence , the measure of angle m∠y = 38°

show that the relation R in R define as R = {(a, b): a<_ b}, is reflexi when transistor but not symmetry
Answer:
R is reflexive and transitive but not symmetric.
Step-by-step explanation:
R = {(a, b); a ≤ b}
Clearly (a, a) ∈ R as a = a.
R is reflexive.
Now,
(2, 4) ∈ R (as 2 < 4)
But, (4, 2) ∉ R as 4 is greater than 2.
R is not symmetric.
Now, let (a, b), (b, c) ∈ R.
Then,
a ≤ b and b ≤ c
→ a ≤ c
→ (a, c) ∈ R
R is transitive.
Thus, R is reflexive and transitive but not symmetric.

Use the triangle to evaluate each function. sin(a) = tan(a) = sec(a) =
The value of the given function is as follows sin a = 3/5, cos a =4/5 and sec a = 5/4.
How do we find the sin, tan, and sec function?By right-angled triangle, we can find the trigonometric function from the sides of the triangle.
sin x = perpendicular/ hypotenuse
cos x = base/ hypotenuse
sec x = hypotenuse /base
From a triangle ABC of base 4, perpendicular 3, and hypotenuse 5, we get
sin a = perpendicular/ hypotenuse
= 3/5
cos a = base/ hypotenuse
= 4/5
sec a = hypotenuse /base
= 5/4
Hence, the value of the given function is as follows sin a = 3/5, cos a =4/5 and sec a = 5/4.

1/2 -> 4/8
3 1/8 -> 3 1/8
Next, I will subtract and simplify as I go.

Can y’all help with this? (It’s exponential and decaying factors). Thanks!!
Answer:
2.37×10^-11 milliliters
Step-by-step explanation:
The exponential model for decay is ...
y = a·b^x
where 'a' is the initial value, 'b' is the decay factor, and x is the number of intervals over which the decay is taking place.
__
Here, you're given an initial value of a=500 mL.
The decay factor is 1 more than the decay rate, so is ...
b = 1 -12% = 0.88
We are asked for the remaining amount after 240 intervals (breaths), so that will be ...
y = 500·0.88^x
y = 500·0.88^240 ≈ 2.37×10^-11 . . . . milliliters

find the missing side
1) 6
2) 6.41
3)6.40
Answer :
6.40. (Option 3)[tex] \\ [/tex]
Step-by-step explanation :
Here, A right angled triangle is given with the measure of two sides and we are to find the measure of the third side.
We'll find the measure of third side with the help of the Pythagorean theorem,
[tex]\\ {\longrightarrow \pmb{\sf {\qquad (Hypotenuse {)}^{2}= (Base) {}^{2} + (Perpendicular {)}^{2} }}} \\ \\[/tex]
Here,
The base (BC) is 4 The perpendicular (AC) is 5The hypotenuse (AB) is c.[tex] \\ [/tex]
So, substituting the values in the formula we get :
[tex]\\ {\longrightarrow \pmb{\sf {\qquad (c {)}^{2}= (4) {}^{2} + (5 {)}^{2} }}} \\ \\[/tex]
[tex] {\longrightarrow \pmb{\sf {\qquad (c {)}^{2}= 16 + 25 }}} \\ \\[/tex]
[tex] {\longrightarrow \pmb{\sf {\qquad (c {)}^{2}= 41 }}} \\ \\[/tex]
[tex] {\longrightarrow \pmb{\sf {\qquad c = \sqrt{41} }}} \\ \\[/tex]
[tex] {\longrightarrow \pmb{\frak {\qquad c \approx 6.40 }}} \\ \\[/tex]
Therefore,
The measure of the third side (c) is 6.40 .Step-by-step explanation:
As it is a right angle triangle , So
Hypotenuse = C unitsBase = 4 unitsperpendicular = 5 unitsWe have to find the value of hypotenuse i.e C
By Pythagoras theorem
H² = P² + B²
putting the known values ,
C² = 5² + 4²
C² = 41 units
C = √41 units
C = 6.40 units
Alex is playing a game

every time his ball hits the
target. He gets an extra 8
points every time his ball
hits the target 8 times in a
row. How many points will
Brady receive if he hits the
target 8 times in a row?
Answer:
72 points
Something important to note is that 8 is the constant,If you can get 8 each time that would be the same as doing 8+8+8...
If he hits it 8 times in a row, that means the constant was being multiplied 8 times, 8+8+8+8+8+8+8+8=64The problem also states that if he hits it 8 times in a row you add 8 more points.
64+8=72
Therefore, the answer is 72There are 72 points Brady receive if he hits the target 8 times in a row.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Alex is playing a game where he gets 8 points 8 every time his ball hits the target.
And, He gets an extra 8 points every time his ball hits the target 8 times in a row.
Hence, Number of points Brady receive if he hits the target 8 times in a row is,
⇒ 8 x 8 + 8
⇒ 64 + 8
⇒ 72
Thus, There are 72 points Brady receive if he hits the target 8 times in a row.
