Answer:
x = 4 units
Step-by-step explanation:
2/z = z/6
z² = 12
z = 2√3
using the Pythagorean theorem:
x² = 12 + 2²
x² = 16
x = 4
Based on the definition of an equilateral triangle, the value of x is: B. 4 units.
What is an Equilateral Triangle?An equilateral triangle is a triangle whose three sides have the same length, and all three interior angles are equal to 60 degrees each.If triangle MRN is created when an equilateral triangle is folded in half, therefore:
x = 1/2 of (NM)
x = 1/2(6 + 2)
x = 1/2(8)
x = 4 units
Therefore, based on the definition of an equilateral triangle, the value of x is: B. 4 units.

Bella can run a mile in 9.54 minutes. Linda can run a mile in 8.22 minutes. How much faster can Linda run than Bella? Justify your reasoning.
Answer:1.16 times
Step-by-step explanation:
Given
Bella can run a mile in 9.54 minutes
Linda can run a mile in 8.22 minutes
We know, [tex]\text{distance=speed}\times\text{ time}[/tex]
Speed of Bella, for running a mile is
[tex]\Rightarrow v_b=\dfrac{1}{\frac{9.54}{60}}=\dfrac{60}{9.54}\\\\\Rightarrow v_b=6.29\ mph[/tex]
Speed of Linda, for running a mile is
[tex]\Rightarrow v_l=\dfrac{1}{\frac{8.22}{60}}=\dfrac{60}{8.22}\\\\\Rightarrow v_l=7.29\ mph[/tex]
So, Linda is faster than Bella, as her speed is more compared to Linda.
Linda is [tex]\frac{9.54}{8.22}=1.16[/tex] times faster than bella
A boat travelled 336 km downstream with the current. The trip downstream took 12 hours.
a) Come up with an equation to describe this relationship
b) If the current is moving at 2 km/h, how fast is the boat moving from its engine?
Answer:
We know the distance (d) equation in terms of rate (r) and time (t) as:
d=rt
Step-by-step explanation:
We have given d=336 km and t= 12 hours, so we have: 336 km = 12t <-- this is our equation.
Divide each side by 12 to solve for t:
12t/12=336/12
t= 28 km/ hour
Brent leaves school to go home. He walks 10 blocks north and then 6 blocks west. If Brent could walk in a straight line to the school, what is the exact distance between Brent and school
Answer:
11.66 units
Step-by-step explanation:
Given that he walks 10 blocks north and then 6 blocks west..
When combined with the straight line to the school, this forms a right angled triangle with the straight line as the hypotenuse.
Hence, let the straight line be h
h^2 = 10^2 + 6^2 (using Pythagoras theorem)
h^2 = 100 + 36
h^2 = 136
h = √ 136
h = 11.66 units

The area of triangle is 72.62 square meters.
What is a triangle?A triangle is a flat geometric figure that has three sides and three angles. The sum of the interior angles of a triangle is equal to 180°. The exterior angles sum up to 360°.
For the given situation,
The sides of triangle are
a = 20 meters, b = 10 meters, c = 15 meters
The formula of area of triangle is
[tex]A=\sqrt{s(s-a)(s-b)(s-c)}[/tex], where
[tex]s=\frac{a+b+c}{2}[/tex]
Now, calculate s as
[tex]s=\frac{20+10+15}{2}[/tex]
⇒ [tex]s=\frac{45}{2}[/tex]
⇒ [tex]s=22.5[/tex]
Thus area of triangle is
⇒ [tex]A=\sqrt{22.5(22.5-20)(22.5-10)(22.5-15)}[/tex]
⇒ [tex]A=\sqrt{22.5(2.5)(-12.5)(-7.5)}[/tex]
⇒ [tex]A=\sqrt{5273.4375}[/tex]
⇒ [tex]A=72.618[/tex] ≈ [tex]72.62[/tex]
Hence we can conclude that the area of triangle is 72.62 square meters.

The eight-digit number ppppqqqq, where p and q are digits, is a multiple

Answer:
There are two possible numbers: 99 990 000 and 44 445 555
Step-by-step explanation:
The multiples of 45 are 5 and 9
There are two possible numbers: 99 990 000 and 44 445 555.
What will be the two numbers?
Numbers are the numerical values like 1,2,3 etc.It is given that The eight-digit number ppppqqqq, where p and q are digits, is a multiple of 45.
Every multiple of 45 is a multiple of both 5 and 9 here P and Q are single-digit integers.
By using the rules of divisibility we can see that if q=0 or q =5 so 4P+4q is a multiple of 9.
If q=0 4P is a multiple of 9 P=9
If q =5 ( 4p + 5 ) is a multiple of 9
Hence p + 5 = 9 and p =4
Therefore there are two possible numbers: 99 990 000 and 44 445 555.

Find the exact angular velocity in radians per hour wind W= 4.1 rpm
Answer:
1545.66 rad/h
Step-by-step explanation:
We need to find the angular velocity in rad/hour when wind is moving with a speed of 4.1 rpm.
We know that,
1 revolution = 2π rad
1 hour = 60 minute
So,
[tex]4.1\ rmm = 4.1\times \dfrac{2\pi }{(\dfrac{1}{60})}\ rad/h\\\\=1545.66\ rad/h[/tex]
So, the required angular velocity is 1545.66 rad/h.

Here is how Noah solved his math problem. Do you agree with his method?
Explain why or why not.
Noah's method:
add 9 to each side
2(x - 9) = 10
2(x-9)+9 = 10 + 9
2x = 19
2x - 2 = 19-2
19
2
divide each side by 2
X=
No, because he kept adding to both sides rather than distributing 2 from x and 9 from the start
Answer:
I don't agree with his method because he should've used the distribute method for the first step. For step 2, he would've needed to add 18 on both sides. Step 3 would be for him to divide both sides by 2, not subtract 2.
Step-by-step explanation:
2(x - 9) = 10
step one: distribute
⇒ 2x - 18 = 10
step two: add 18 on both sides and then simplify
⇒ 2x - 18 + 18 = 10 + 18
⇒ 2x = 28
step three: divide both sides by 2
⇒ [tex]\frac{2x}{2} = \frac{28}{2}[/tex]
⇒ x = 14

Answer:
64,26
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
The box means its is a 90 degree angle
90 + 2x+ x-6 = 180
Combine like terms
84+3x = 180
Subtract 84 from each side
84+3x-84 = 180-84
3x=96
Divide by 3
3x/3 = 96/3
x = 32
The top angle is
2x = 2*32 = 64

3(2)^(n-1)3(-2)^(n-1)2(3)^(n-1)not geometric2(-3)^(n-1)Step-by-step explanation:
For these, you can find the appropriate formula by looking at the ratio of the first two terms. That will be the number in parentheses in the explicit formula. If there is no match, it is not geometric.
6/3 = 2 . . . an = 3(2)^(n-1)-6/3 = -2 . . . an = 3(-2)^(n-1)6/2 = 3 . . . an = 2(3)^(n-1)5/2 = 2.5 . . . not geometric (arithmetic sequence: an = 2+3(n -1))-6/2 = -3 . . . an = 2(-3)^(n-1)Distribute (2m-5m)(-5)
First Method (Distributive Property)
(2m - 5m) (-5)
Rearrange the equation to make it easier.
(-5) (2m - 5m)
In distributive property, it's all about multiplying. The -5 goes to the 2m and the 5m. Like this: (-5 • 2m) - (-5 • 5m).
-10m + 25m
15m
Second Method
(2m - 5m) (-5)
Since 2m and 5m have the same variable, we can subtract them.
(-3m) (-5)
Multiply.

∠A and ∠ B ∠B are supplementary angles. If m ∠ A = ( 4 x − 16 ) ∘ ∠A=(4x−16) ∘ and m ∠ B = ( 8 x + 4 ) ∘ ∠B=(8x+4) ∘ , then find the measure of ∠ A ∠A.
Answer:
∠ A = 48°
Step-by-step explanation:
Supplementary angles are those angles that measure up to 180 degrees.
∠A and ∠B are supplementary angles. If m ∠ A = ( 4 x − 16 ) ∘ and m ∠ B = ( 8 x + 4 ) ∘,then find the measure of ∠ A
Step 1
∠A + ∠B = 180°
(4x−16)° + (8x+4)° = 180
4x - 16 + 8x + 4 = 180
12x -12 = 180
12x = 180 + 12
12x = 192
x = 192/12
x = 16
Step 2
To find the measure of ∠ A
∠ A = 4x - 16
= 4 × 16 - 16
= 64 - 16
= 48°
Therefore,
∠ A = 48°
