Answer:
Both answers are the first option.
Step-by-step explanation:
Question 1: 27 is greater than -49, so that is why the first option for question one is correct.
Question 2:-49 is less than 27 so that is why 2005 had less rain compared to 2004.
The correct inequality comparison is 27 > -49.
The correct description is: There was less rain in 2005 than in 2004.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
When we compare the relative amounts of rain in the table, we see that the amount of rain in 2005 (-49 cm) is less than the amount of rain in 2004 (27 cm).
The correct inequality comparison is: 27 > -49
The minus sign in front of 49cm in 2005 indicates that the amount of rain is less than the amount of rain in 2000.
So, the correct description is: There was less rain in 2005 than in 2004.

Mason wants to play with Maliyah's Doll House, but first he needs to stop at the clubhouse. If all
three stops are in the shape of a triangle, which of the following distances would NOT be an option?
Answer:
B, (6,8,14)
Step-by-step explanation:
6+8 is equal to 14, not greater than 14
If all three stops are in the shape of a triangle then the distances 6 8 14 would not be an option.
Let us Apply the triangle inequality to the options.
A)5+6>9
6+9>5
5+9>6
So the triangle is possible.
B) 6+8=14 while the condition is that the sum of any two sides in a triangle is always greater than the third side i.e 6+8 must be greater than 14.
So, the triangle is not possible.
Similarly, C and D are possible triangles.
Hence, out of the 4 options, the distances 6 8 14 would not be an option.

What is the perimeter, in feet, of a rectangle whose length is twice its width and whose width is 5 feet
9514 1404 393
Answer:
30 ft
Step-by-step explanation:
The width is 5 ft. The length is twice that, so is 10 ft. The perimeter is given by the formula ...
P = 2(L +W)
P = 2(10 ft + 5 ft) = 2(15 ft)
P = 30 ft
The perimeter of the rectangle is 30 feet.
Truck A leaves station 1 at 9:00 a.m. and travels at the rate of 60 kph. After 2 hours, Truck B leaves the same station and travels in the same direction at the rate of 80 kph. At what time will Truck B overtake Truck A?
Answer: [tex]5:00\ PM[/tex]
Step-by-step explanation:
Given
Truck A speed is [tex]v_a=60\ kmph[/tex]
Truck B speed is [tex]v_b=80\ kmph[/tex]
Truck A leaves 2 hours before truck B
Distance traveled in the 2 hour
[tex]\Rightarrow 60\times 2=120\ km[/tex]
Suppose Truck B will catch truck A after t hours
[tex]\therefore 120+60t=80t[/tex]
[tex]\Rightarrow 120=20t\\\Rightarrow t=6\ hr[/tex]
Overtake time is [tex]9:00am +2+6=5:00\ PM[/tex]
If the Math Olympiad Club consists of 13 students, how many different teams of 5 students can be formed for competitions?
Answer:
2 teams
Step-by-step explanation:
13 divided by 5 is 2.6, but you cannot split a person in half, so it would be two teams with a remainder of three people.
There are 1287 different teams of 5 students can be formed for competitions.
What is Combination?A combination is a technique to determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
Given that;
The Math Olympiad Club consists of 13 students.
And, To form different teams of 5 students can be formed for competition.
Hence, We get;
Number of different teams of 5 students can be formed for competitions is,
⇒ ¹³ C ₅
⇒ 13! / 5! 8!
⇒ 1287
Thus, There are 1287 different teams of 5 students can be formed for competitions.

Answer:
51°
Step-by-step explanation:
The angles where the expressions are given are a linear pair, so total 180°.
(3x +15) +(10x +9) = 180
13x = 156 . . . . . . . . . . . . . . . subtract 24, collect terms
x = 156/13 = 12
Then the acute angle is ...
3x +15 = 3(12) +15 = 36 +15 = 51
The stairs make an angle of 51° with the basement floor.
_____
Additional comment
Building code requires the rise to be not more than 8 and the run not less than 9, so the maximum angle is about 41.6°. A 51° staircase would not meet code.

Annabelle’s bicycle has a wheel radius of 13 inches. She places a sticker on the wheel so that its minimum height above the ground is 0.5 inches. When she rides her bicycle, the wheel completes 90 revolutions every minute. The sticker begins at its minimum height above the ground. Which equation models the height in inches of the sticker after x minutes? y = 0.5 sine (180 pi x) + 13 y = 12.5 sine (180 pi x) + 13 y = 0.5 sine (180 pi x minus StartFraction pi Over 2 EndFraction) + 13 y = 12.5 sine (180 pi x minus StartFraction pi over 2 EndFraction) + 13
Answer:
[tex]y=12.5 sin(180\pi x-\frac{\pi}{2})+13[/tex]
Step-by-step explanation:
In order to solve this we can start by drawing a sketch of the problem (see attached picture)
So fist, let's take the general form of a sinusoidal movement:
[tex]y=Asin(\omega x+\phi)+b[/tex]
where:
A= amplitude
[tex]\omega[/tex]= angular frequency
x= time
[tex]\phi[/tex] = horizontal shift
b= vertical shift.
In this case, the amplitude will be the maximum distance between the center of the wheel and the highest or lowest point of the trajectory, in this case:
A= 13in - 0.5in =12.5 in
The angular frequency is how many radians the wheel will turn in a minute, so we get:
[tex]\omega=\frac{90 rev}{min}*\frac{2\pi rad}{1 rev}[/tex]
[tex]\omega=180\pi rad/min[/tex]
Generally, the sin function will start at the center of the circular movement. In this case, since it starts on the lowest point, we can say that the graph moves right by [tex]\frac{\pi}{2} rad[/tex], so in this case:
[tex]\phi=-\frac{\pi}{2}[/tex]
and finally, the vertical shift is the distance between the center of the circular movement and the ground so in this case:
b=13in
so when putting it all together we get our equation to be:
[tex]y=12.5 sin(180\pi x-\frac{\pi}{2})+13[/tex]
