Answer:
[tex]tan 56 = \frac{26}{x}[/tex]
Step-by-step explanation:
[tex]tangent = \frac{opposite}{adjacent}[/tex]
Side z is the hypotenuse, since it is opposite the right angle.
Side x is the adjacent, since it is next to the angle you are solving for.
The side measuring 26 is the opposite, since it is opposite the angle you are solving for.

Answer:
x=9
Step-by-step explanation:
[tex]\frac{x+6}{x} =\frac{20}{(20-8)} \\1+\frac{6}{x} =\frac{20}{12} \\\frac{6}{x} =\frac{20}{12} -1\\\frac{6}{x} =\frac{20-12}{12} \\\frac{6}{x} =\frac{8}{12} \\8x=6 \times 12\\8x=72\\x=\frac{72}{8} =9\\x=9[/tex]
Answer:
9
Step-by-step explanation:
The left side of the triangle is 20 units long, the bottom portion is 8 units long.
This means the top portion must be 12 units long, 20 - 8 = 12.
The ratio between the left and right side has to be the same because they are two straight lines.
So if the ration is 8 to 6 or 8/6 which reduces to 4/3 then your ration is 12 to x.
So if... 4/3x=12 then
(3)4/3x = 12(3) multiply both sides by 3
4x = 36 the divide both sides by 4
x = 9
To check you can multipy your answer, in this case 9 by 4/3.
(9)(4/3) =
(9 x 4)/3 =
36/3 = 12
You did it! Hope this helped.

7. (07.03) An equation is shown below: 4(2x - 5) + 15 = 11 Write the steps you will use to solve the equation and explain each step. (5 points)
Answer:
x = 2
Step-by-step explanation:
[tex]4(2x-5)+15 = 11 => 4(2x-5) = 11 - 15 => 4(2x-5) = -4 => 2x-5 = \frac{-4}{4} => 2x-5 = -1 => 2x = -1 + 5 => 2x = 4 => x = 2[/tex]
The value of x is 2 for equation 4(2x - 5) + 15 = 11
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 4(2x - 5) + 15 = 11
Four times of two x minus five plus fifteen equal to eleven
4(2x - 5) + 15 = 11
Apply distributive property on the LHS
8x-20+15=11
8x-5=11
Add 5 on both sides
8x=16
Divide both sides by 8
x=2
Hence, the value of x is 2 for equation 4(2x - 5) + 15 = 11

Josh can long-jump 195% of his height with a running start. If Josh is 66 inches tall, how far can he long-jump?
Answer: 128.7 inches
Step-by-step explanation:
Josh's height is 66 inches.
When he jumps with a running start, he can jump as far as 195% of his height.
The length he can jump is therefore 195% multiplied by his height:
= Josh height * 195%
= 66 * 195/100
= 128.7 inches
Answer: 128.7

circumference of
18.84 meters.
What is the
diameter of the
pool?
(use

IS
Answer:
6 MetersExplanation:
Diameter = Circumference ÷ πCircumference: 18.84
π: 3.14
18.84 ÷ 3.14
= 6 MetersWhat is the mathematical
representation of 20P4?
The mathematical representation of 20P4 is [tex]^{20}P_4 = 20 \times 19 \times 18 \times 17[/tex]. so option C is the correct.
How many ways k things out of m different things (m ≥ k) can be chosen if order of the chosen things doesn't matter?We can use combinations for this case,
The Total number of distinguishable things is m.
Here, Out of those m things, k things are to be chosen such that their order doesn't matter.
This can be done in total of
[tex]^mC_k = \dfrac{m!}{k! \times (m-k)!} ways.[/tex]
If the order matters, then each of those choice of k distinct items would be permuted k! times,
So, total number of choices in that case would be:
[tex]^mP_k = k! \times ^mC_k = k! \times \dfrac{m!}{k! \times (m-k)!} = \dfrac{m!}{ (m-k)!}\\\\^mP_k = \dfrac{m!}{ (m-k)!}[/tex]
This is called permutation of k items chosen out of m items (all distinct).
We have to find the mathematical representation of 20P4.
[tex]^{20}P_4[/tex]
here, m = 20
k = 4
Now substitute;
[tex]^mP_k = \dfrac{m!}{ (m-k)!}\\\\^{20}P_4 = \dfrac{20!}{ (20-4)!}\\\\^{20}P_4 = \dfrac{20!}{ (16)!}\\\\\\^{20}P_4 = \dfrac{20 \times 19 \times 18 \times 17 \times 16!}{ (16)!}\\\\\\^{20}P_4 = 20 \times 19 \times 18 \times 17[/tex]
Hence, the mathematical representation of 20P4 is [tex]^{20}P_4 = 20 \times 19 \times 18 \times 17[/tex]. so option C is the correct.
