What is the value of a?
Answer:
a = 13
Step-by-step explanation:
The three angles of any triangle MUST add up to 180°. Thus, 3a + 8a + 37 = 180, and 11a = 180 - 37 = 143.
If 11a = 143, then a = 143/11 = 13
a = 13
Answer:
a = 13
Step-by-step explanation:
8a + 3a + 37° = 180°
11a + 37° = 180°
11a = 180° - 37°
11a = 143°
a = 143/11
a = 13

A toy soldier set a selection of 6 weapons for 3 soldiers.
How many different ways can the 3 soldiers be assigned weapons if each soldier is to be assigned only one weapon?
Answer:
2
Step-by-step explanation:
There are 120 different ways to assign 6 weapons to 3 soldiers, each receiving one weapon, calculated using permutations.
Calculating Permutations for Weapons Assignment
To determine how many different ways 3 soldiers can be assigned weapons from a selection of 6, we need to calculate the permutations of 6 objects taken 3 at a time. We use the permutation formula, which is expressed as P(n, k) = n! / (n-k)!, where n is the total number of items, and k is the number of items to choose. In this case, n is 6 (the total number of weapons), and k is 3 (the total number of soldiers).
We calculate the permutations as follows:
6! / (6-3)! = (6 * 5 * 4) / (3 * 2 * 1) = 120 ways.
Therefore, there are 120 different ways to assign the weapons to the soldiers, with each soldier getting one weapon.

Answer:
20
Step-by-step explanation:
Because it is a square table, that means all the sides are even. And to find the area, we do Height * Base. But again, because they're even, we would just need to find 2 numbers that multiply to be 400. And that number, is 20. 20 * 20 = 400. So the length of one side is 20.

What is the value of n in the equation 1 (n – 4) – 3 = 3 - (2n+3)?
Answer:
n=7/3
Step-by-step explanation:
1 (n – 4) – 3 = 3 - (2n+3)
1. distribute the 1 on the left side and distribute the -1 on the right side
1n-4-3=3-2n-3
2. add like terms
1n-7=-2n
3. move n to one side and by itself
-7=-3n
4. divide -3 to get n alone. Both negatives cancel out each other
7/3=n
Step-by-step explanation:
[tex]1(n-4)-3=3-(2n+3)[/tex]
[tex]n-4-3=3-2n-3\\n+2n=3-3+3+4\\3n=7\\n=\frac{7}{3}[/tex]

At the U.S. Open Tennis Championship, a statistician keeps track of every serve that a player hits during the tournament. The statistician reported that the mean serve speed of a particular player was 100 miles per hour (mph) and the standard deviation of the serve speeds was 10 mph.
Using the z-score approach for detecting outliers, which of the following serve speeds would represent outliers in the distribution of the player's serve speeds?
Speeds: 65 mph, 110 mph, and 120 mph.
Answer:
The speed of 65 mph is an outlier in the distribution of the player's serve speeds
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 100 mph
Standard Deviation, σ = 10 mph
Formula:
[tex]z_{score} = \displaystyle\frac{x-\mu}{\sigma}[/tex]
Outlier on basis of z-score:
Any z-score greater than 3 or less than -3 is considered to be an outlier. This rule of thumb is based on the empirical rule.Calculation of z-score:
[tex]x = 65\Rightarrow z = \dfrac{65-100}{10} = -3.5\\\\x = 110\Rightarrow z = \dfrac{110-100}{10} = 1\\\\x = 120\Rightarrow z = \dfrac{120-100}{10} = 2[/tex]
Thus, the speed of 65 mph is an outlier in the distribution of the player's serve speeds as the corresponding z-score is less than -3.

If a cone shares a base with a cylinder, and the
volume of the cylinder is given, along with the
heights of the cylinder and of the cone, how could
you find the volume of the cone?
Answer:
cone volume = cylinder volume times 1/3 the ratio of cone height to cylinder height
Step-by-step explanation:
Let h1 and V1 represent the height and volume of the cylinder, and h2 and V2 the height and volume of the cone.
We are told they have a common base area (B), so ...
V1 = Bh1 ⇒ B = V1/h1
V2 = (1/3)Bh2 = (1/3)(V1/h1)h2
The volume of the cone is ...
V2 = h2/(3h1)×V1
"one-third the ratio of cone height to cylinder height, multiplied by the cylinder volume."
Abigail has a cylindrical candle mold with the dimensions shown. If Abigail has a rectangular block of wax measuring 15 cm by 12 cm by 18 cm, about how many candles can she make after melting the block of wax? Round to the nearest tenth.
Find the volume of the candle using the formula for volume of a cylinder:
V = PI x r^2 x h = 3.14 x 3.4^2 x 6 = 217.79 cubic cm. Round to 217.8
Find the volume of the block: V = l x w x h = 15 x 12 x 18 = 3,240 cubic cm.
Now divide the volume of the block by the volume of a candle:
3240 / 217.8 = 14.88
Round to the nearest tenth = 14.9 candles.
Number of cylindrical candles after melting the rectangular block is 14.9.
What is cylinder?" Cylinder is a three dimensional surface formed by two parallel lines and two parallel circular base."
What is volume?" Volume is the total amount of space occupied by any 3 dimensional body."
Formula used
Volume of a cylinder = π r²h
Volume of a rectangular block = length × width ×height
According to the question,
Height of a cylinder = 6cm
radius of cylinder = 3.4cm
Length of a block = 15cm
width of a block = 12cm
height of a block = 18cm
Volume of a cylinder = [tex]3.14[/tex]× [tex](3.4)^{2}[/tex]×[tex]6[/tex]
=217.8 cubic cm
Volume of rectangular block = [tex]15[/tex] × [tex]12[/tex] × [tex]18[/tex]
= 3240 cubic cm
Number of candles = Volume of rectangular block / volume of cylinder
= [tex]\frac{3240}{217.8}[/tex]
= 14.88
= 14.9 (nearest tenth)
Hence the Number of cylindrical candles after melting the rectangular block is 14.9.

a loaded truck is traveling 20 mph faster than a freight train. In the time it takes the train to travel 160 miles, the truck travels 240 miles. find the speed of the truck
To find the speed of the truck, start by assigning the speed of the train as 'x', then the truck's speed is 'x + 20'. Set up an equation based on the principle of time = distance/speed, make them equal to each other then solve for 'x'. The truck's speed will be 'x + 20'.
Explanation:Let's call the speed of the freight train 'x' (in mph). We know from the question, that the loaded truck is traveling 20 mph faster than the train, so the truck's speed is 'x + 20' mph.
Given that the time it takes for the train to travel 160 miles is the same time it takes the truck to travel 240 miles, we can write an equation based on the principle that time equals distance divided by speed.
For the train, time = 160/x and for the truck, time = 240/(x+20). As both times are equal, we can write the equation as:
160/x = 240/(x + 20).
Solving this equation for 'x' will give us the speed of the freight train in mph. Then, by adding 20 to 'x', we can find the speed of the truck.

Giselle works as a carpenter
The stopping distance of a car is modeled by the function d = 0.05r(r + 2) where d is the stopping distance of the car measured in feet and r is the speed of the car in miles per hour. If skid marks left on the road are 75 feet long, how fast was the car traveling?
Answer:
The car was moving approximately at a speed of 37.74 miles per hour.
Step-by-step explanation:
We are given the following in the question:
The stopping distance of a car is given by
[tex]d = 0.05r(r + 2)[/tex]
where d is the stopping distance in feet and r is speed of the car in miles per hour.
The stopping distance is 75 feet, we have to find the speed of the car,
Putting d = 75 in the equation, we get,
[tex]75 = 0.05r(r + 2)\\r^2 + 2r = 1500\\r^2 + 2r-1500 = 0\\\\r =\dfrac{-2\pm \sqrt{4-(4)(1)(-1500)}}{2}\\\\r\approx -39.74,37.74[/tex]
Thus, the car was moving approximately at a speed of 37.74 miles per hour.

A motorboat takes 5 hours to travel 200 miles going upstream. The return trip takes 4 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?
Answer:
rate of motorboat: b
rate of current: c
So the rate the boat travels upstream is $b - c$, and the rate it travels downstream is $b + c$
Step-by-step explanation:
d = rt
200 = (b - c)\cdot 5
200 = (b + c)\cdot 4
b - c = 40
b + c = 50
Adding these equations, we get:
2b = 90
b = 45
So
c = 50 - 45 = 5
Therefore the rate of the boat is 45kph, and the rate of the current is 5kph
Hope this helps :)
Final answer:
The boat has a speed of 45 mph in still water, and the current runs at 5 mph. By using the given times and distances for upstream and downstream travel, we can set up equations to solve for the boat's speed and the current's speed.
Explanation:
To find the rate of the boat in still water and the rate of the current, let's denote the boat's speed in still water as b and the speed of the current as c. When the boat goes upstream, its effective speed is b - c, and when it goes downstream, its effective speed is b + c. We can translate this into two equations based on the information given:
(b - c) × 5 hours = 200 miles (upstream)
(b + c) × 4 hours = 200 miles (downstream)
By dividing the distance by the time, we can solve for the effective speeds upstream and downstream.
b - c = 200 miles / 5 hours = 40 mph
b + c = 200 miles / 4 hours = 50 mph
Add these two equations:
2b = 90 mph
b = 45 mph (boat's speed in still water)
Next, subtract the first equation from the second:
2c = 10 mph
c = 5 mph (current's speed)
So, the boat has a speed of 45 mph in still water, and the current has a speed of 5 mph.
