Step-by-step explanation:
The general rule is that any two leg lengths must exceed the third.
A) won't. 1 + 1 = 2. The 2 ones lay flat across the 2.
B) 2 + 1 = 3. Won't work for the same reason as A
C) works fine. Any 2 will exceed the third.
D) can't happen. 7 + 7 < 15.

A wire makes a 70 degrees angle with the ground and is attached to the top of a 50 ft. antenna. How long is the wire?
Answer:
53.2 ft
Step-by-step explanation:
A wire makes a 70 degrees angle with the ground and is attached to the top of a 50 ft. antenna. How long is the wire?
We solve the above question using the Trigonometric function of Sine
sin theta = Opposite/Hypotenuse
Theta = 70°
Hypotenuse = x = Length of the wire
Opposite = 50ft antenna
Hence,
sin 70 = 50/x
Cross Multiply
50 = sin 70 × x
x = 50/sin 70
x = 53.208888624 ft
Approximately x = 53.2 ft
The length of the wire is 53.2 ft

Answer: 1X52=73
Step-by-step explanation:
\begin{aligned} f(x)&=|x| \\\\ g(x)&=|x | + 1 \end{aligned} f(x) g(x) =∣x∣ =∣x∣+1 We can think of ggg as a translated (shifted) version of fff. Complete the description of the transformation. Use nonnegative numbers. To get the function ggg, shift fff by units.
Answer:
To get the function g, shift f by 1 unit.
Step-by-step explanation:
Given
[tex]\begin{aligned} f(x)&;=|x| \\ g(x)&;=|x | + 1 \end{aligned}[/tex]
Required
How do f(x) translates to g(x)
In terms of f(x), g(x) can be represented as:
[tex]g(x) = f(x) + k[/tex]
Where
[tex]f(x)= |x|[/tex]
and
[tex]k = 1[/tex]
This implies that f(x) is vertically shifted 1 unit up to get g(x)
Answer:
To get the function g, shift f up by 4 units and to the left by 2 units.
Step-by-step explanation:
To get the function g, shift f up by 4 units and to the left by 2 units.

Solve for y. 2(3y-7)=16
Answer:
y=5
Step-by-step explanation:
First, distribute the 2 to the 3y and -7
6y - 14 = 16
Second, add 14 to both sides.
6y = 30
Third, divide both sides by 6
y = 5
As you can see y equals 5!
I hope the explanation helped and have a great day!
Answer:
y = 5
Step-by-step explanation:
2(3y - 7) = 16
distributive property:
2(3y - 7) = 16
6y - 14 = 16
add 14 on both sides
6y - 14 + 14 = 16 + 14
6y = 30
divide both sides by 6 :
[tex]\frac{6y}{6} = \frac{30}{6}[/tex]
y = 5
to check, subtitute 5 for y
2 (3(5) - 7) = 16
2(18 - 7) = 16
30 - 14 = 16
16 = 16

Answer:
D
Step-by-step explanation:
The volume (V) of a cone is calculated as
V = [tex]\frac{1}{3}[/tex] πr²h ( r is the radius and h the height )
Here V = 226 and r = 12 ÷ 2 = 6 , then
[tex]\frac{1}{3}[/tex]π × 6²h = 226 ( multiply both sides by 3 to clear the fraction )
3.14 × 36h = 678
113.04h = 678 ( divide both sides by 113.04 )
h = [tex]\frac{678}{113.04}[/tex] ≈ 6 m ( to the nearest metre )
the letters of the alphabet are written on pieces of paper and put into a hat. they are then pulled out and not replaced.
a) what is the chance of pulling out an A and then a Z in two consecutive turns?
b) starting again, what is the chance of pulling out two vowels in two consecutive turns?
Answer:
A: 3.84% chance.
B: 23.08% chance
The chance of pulling out an A and then a Z and two vowels in two consecutive turns will be 1 / 650 and 2 / 65, respectively.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
The letters of the alphabet are written on pieces of paper and put into a hat. they are then pulled out and not replaced.
Then the total number of letters of the alphabet will be 26.
Then the chance of pulling out an A and then a Z in two consecutive turns will be given as,
P = (1 / 26) x (1 / 25)
P = 1/650
The chance of pulling out two vowels in two consecutive turns will be given as,
P = (5 / 26) x (4 / 25)
P = 20 / 650
P = 2 / 65
The chance of pulling out an A and then a Z and two vowels in two consecutive turns will be 1 / 650 and 2 / 65, respectively.

If a driver takes 6 hours to get to the town market which is 336 km away from his house, what is his average speed?
Answer:
[tex]56\ \text{km/h}[/tex]
Step-by-step explanation:
[tex]t[/tex] = Time taken = [tex]6\ \text{hours}[/tex]
[tex]d[/tex] = Distance = [tex]336\ \text{km}[/tex]
Average speed is given by
[tex]s=\dfrac{\text{Distance}}{\text{Time}}=\dfrac{d}{t}[/tex]
