Answer:
A) 2 cm
Step-by-step explanation:
By definition, regular polygons have equal sides and angles. Therefore, each side of the regular hexagon must be equal. Since one side is marked as 2 cm, the length of PQ must also be 2 cm.

Hey can anyone help with this question?
Answers
Answer:
Step-by-step explanation:
When you learn calculus you'll be able to do this by hand (without a calculator) but for now we have to just kind of guess. We know that 8 x 8 = 64 and 9 x 9 = 81, so the number is between 8 and 9. Since 68 is closer to 64 than it is to 81, the number is closer to 8. Like less than 8.5. 8.1 squared is 65.61, (you can do this by hand...without a calculator) and 8.2 squared is 67.24, and 8.3 squared is 68.89. 8.3 squared is too high while 8.1 squared was too low; the estimation to the nearest tenth is 8.2

What is the explicit formula for this sequence?
6, 2, -2, -6, ...
Answers
Answer:
B
Step-by-step explanation:
this is just common sense. if you would have tried you could have easily answered this yourself.
the sequence starts with 6. that is a1.
so, the formula simply has to add "something" to 6.
therefore, A and D are out.
and then we see immediately that the sequence is built by subtracting 4 (or adding -4) for every step.
so, we need to add multiples of -4.
therefore, only B is correct (C adds multiples of +4).

Phythagorean theorem help me plsss
Answers
Answer:
5
Step-by-step explanation:
We know that a^2+b^2=c^2 from the Pythagorean theorem where a and b are the legs and c is the hypotenuse
4^2+3^2 = c^2
16+9 = c^2
25 = c^2
Taking the square root of each side
sqrt(25) = sqrt(c^2)
5 =c
Answer:
d = 5 m
Step-by-step explanation:
The diagonal divides the rectangle into 2 right triangles with legs 3 and 4 and hypotenuse h
Using Pythagoras' identity in one of the right triangles, then
d² = 3² + 4² = 9 + 16 = 25 ( take the square root of both sides )
d = [tex]\sqrt{25}[/tex] = 5

Find the lowest common multiple (LCM) of 28 and 35.
Answers
Step-by-step explanation: I would first create a factor tree for these numbers and break them down into their prime factorization.
First, 28 is 7 x 4 and 4 is 2 x 2
Next, 35 is 7 x 5
In our factors tree, a 7 is a factor that is shared so we pull out a 7.
Now, we multiply all of our factors that don't pair up
and in this case, that's a 2, another 2, and a 5.
So our LCM is 7 x 2 x 2 x 5 or 140.
140
the lcm of two non-zero integers ×(28) and y(35) ,is the smallest posetive integer m(140) that is divisibleby both ×(28)and y(35) Without any remainder
Divide 360 between Kunal and Mohit in the ratio of 7:8
Answers
Answer:
K = 168 M = 192
Step-by-step explanation:
7:8 = 15
?:? = 360
Divide
360 / 15 = 24
Multiply
24 × 7 = 168
24 × 8 = 192
168:192 = 360
So, Kunal gets $168 and Mohit gets $192.
Step-by-step explanation:
Let the common ratio = x
Kunal = 7x
Mohit = 8x
Total value = 360
we know,
7x + 8x = 360
15x = 360
x = 360÷15
x = 24
so,
Kunal = 7x = 7×24=168
Mohit = 8x = 8×24=192
