The mean of 10,12,16,20,p,26 is 17.Find the value of p.
Answers
17 * 6 = 102
10 + 12 + 16 + 20 + 26 = 84
p = 102-84 = 18
p = 18
__________________________________________________
Explanation:
__________________________________________________
The [arithmetic] mean =
{the sum of all the values in the data set}
divided by {the number of values in the number set} ;
__________________________________________________
→ 17 = (10 + 12 + 16 + 20 + 26 + p) / 6 ;
__________________________________________________
→ (10 + 12 + 16 + 20 + 26 + p) = 17 * 6 ;
→ (p + 84) = 102
Subtract "84" from each side of the equation;
to isolate "p" on one side of the equation; & to solve for "p" ;
→ p + 84 – 84 = 102 – 84 ;
→ p = 18 .
_________________________________________________
The answer is: " p = 18 " .

What is volume?Volume is defined as the space occupied within the boundaries of an object in three-dimensional space.
Given that, rectangular box with three sides visible, having width, length, and height of x plus two, two x minus one, and three x plus one
Height = x+2
Width = 2x+1
Length = 3x+1
Volume = HxLxW
Volume = (x+2)(2x+1)(3x+1)
= 2x²-x+4x-2(3x+1)
= (2x²+3x-2)(3x+1)
= 6x³+11x²-3x-2

Find the area of a triangle with a base length of 3 units and a height of 4 units.
Answers
So these are given so we plug them in
A=1/2(3)(4)
A=6 units
To find the area of a triangle, we need to multiply the base and the height of the triangle and divide the product by 2.
So, the expression we would use to solve this is (3 * 4) / 2.
Let's solve:
(3 * 4) / 2
= 12 / 2
= 6
So, the area of the triangle is 6 units squared.

ASAP Plz what is the value of x? Plz no joking around this is from quiz 4.09: Special Right Triangles 2
Answers
Firstly, let's find RT so that we can solve the top triangle.
We could actually use 3 methods to find this side: 1) trig to find RT
2) trig to find ST, then Pythagorean Theorem to determine RT
3) use the special 30-60-90 right triangle rule ... hmm, I'm going with the last because it's easiest ;)
For 30-60-90 triangles, the sides are always as follows: smallest side (opposite the 30) is s, the middle side is sSR3, and the hypotenuse is 2×s
Thus, since we have the side opposite 60, it is = sSR3, so:
[tex]s \sqrt{3} = 2 \sqrt{3} \\ s \sqrt{3} \div \sqrt{3} = 2 \sqrt{3} \div \sqrt{3} \\ s = 2[/tex]
So now, the hypotenuse (RT) = 2s = 2(2) = 4
Secondly, we are looking at the other type of special right triangle, the 45-45-90:
The side opposite the 45s are s (remember side lengths are equal whose opposite angles are equal); and the hypotenuse is always
[tex]s \sqrt{2} [/tex]
we only need QR, which is s, which is also = RT
So the answer is:
QR = x = 4
x = 4 IS THE FINAL ANSWER!!!

Opposite angles of a parallelogram are equal. You get a hint of that from the 2 acute angles which are both 2x.
Add 15 to both sides.
3x = 2x + 24 + 15
3x = 2x + 39 Subtract 2x from both sides.
3x - 2x = 39
x = 39
Hi there! :)
Answer:
x=39
*The answer must have a positive sign.*
Step-by-step explanation:
When the 2 acute angles in which means you had to used 2x from both sides of an equation.
First, only had to do is, add by 15 from both sides of an equation.
[tex]3x-15+15=2x+24+15[/tex]
Then, you add by the numbers from left to right.
[tex]24+15=39[/tex]
[tex]3x=2x+39[/tex]
Next, you subtract by 2x from both sides of an equation.
[tex]3x-2x=2x+39-2x[/tex]
Finally, you simplify.
[tex]x=39[/tex]
Final answer is x=39
Hope this helps!

Maria plans to fill pots in her garden with soil and plant food. Maria has 8 1/2 quarts of soil as 1 1/2 quarts of plant food. Each pot requires 3/4 quart of soil. For how many pots does Maria have enough soil?
Answers
- Maria has 8 1/2 quarts of soil.
- Each pot requires 3/4 quart of soil.
2. Keeping this on mind, you can convert the mixed number 8 1/2 and the fracion 3/4 to decimals, as below:
8 1/2=8.5 quarts
3/4=0.75 quarts
3. Therefore, you have:
1 pot-----0.75 quarts
x-----8.5 quarts
x=(8.5x1)/0.75
x=11 pots
For how many pots does Maria have enough soil?
The answer is: 11 pots

△ABC is similar to △RST . In addition, m∠C=76° and m∠S=3(m∠A) . What is m∠A ? Enter your answer in the box.
Answers
Answer:
∠A = 26°
Explanation:
If two angles of a triangle have measures equal to the measures of two angles of another triangle, then the triangles are similar. In case of similar triangle, corresponding angles are congruent.
Angle ∠C = 76
So, ∠T = 76 because of corresponding angle.
Given that,
m∠S=3(m∠A)
We know that,
∠S ≅ ∠B
That means ∠B = 3 (∠A)
Sum of angles in a triangle = 180°
∠A + ∠B + ∠C = 180°
∠A + 3∠A + 76° = 180°
4∠A = 180° - 76°
4∠A = 104°
∠A = [tex] \frac{104}{4} [/tex]
∠A = 26°

Answers
(4x^-2)^4
= 4^4 x^-8
= 4^4 / x^8
= 256/x^8
Answer:
The value of a is -2 and the value of b is 4.
Step-by-step explanation:
Given expression is,
[tex](4x^a)^b = \frac{256}{x^8}[/tex]
Using [tex](ab)^m=a^m.b^n[/tex] on left side,
[tex]4^b(x)^{ab}=\frac{4^4}{x^8}[/tex] ( [tex]4^4 = 256[/tex] )
Using [tex]a^m=\frac{1}{a^{-m}}[/tex],
[tex]4^b(x)^{ab}=4^4 (x)^{-8}[/tex]
By comparing both sides,
We get,
b = 4 and ab = -8
⇒ a = -2
Hence, the value of a is -2 and the value of b is 4.
