Solve for x. Round to the nearest tenth, if necessary.
ANSWER
14.3
EXPLANATION
angle = 21⁰
opposite side = 5.5
adjacent side = x
Knowing this, we must use tangent (opposite / adjacent)
tan (21⁰) = 5.5 / x
x = 5.5 / tan (21⁰) (use calculator)
x= 14.3

What is the answer to the equation
g(x) = 1/5 × (1/3)^x
X = 3
Step-by-step explanation:
since x=3
1. substitute into the equation
g(3) = 1/5 x (1/3)^3
2. solve
g(3) = 1/5 x (1³/3³)
= 1/5 x (1/27)
= 1/5 x 1/27
= 1/135 (0.00740740741)

Answer:
[x - 5]² + [y + 7]² = 6²
Step-by-step explanation:
It should be noted:
Equation of circle: (x - h)² + (y - k)² = r²"h" represents the x coordinate of the center point, "k" represents the y coordinate of the center point, and "r" represents the radius of the circle.
⇒ h = 5; k = -7; r = 6When the values are substituted:
[x - 5]² + [y - (-7)]² = 6²
⇒ [x - 5]² + [y + 7]² = 6² = 36
A cone has a height of 13 inches and a radius of 6 inches. What is its volume?
Answer:

Amy received a $80 gift card for a coffee store. She used it in buying some coffee that cost $8.17 per pound. After buying the coffee, she had $55.49 left on her card. How many pounds of coffee did she buy?
Answer:
I think you need more info
Answer:
Pretty sure the answer is 3 pounds you can pretty much repeatedly take away 8.17 from 80 till you get 55.49
80 - 8.17 = 71.83
71.83 - 8.17 = 63.66
63.66 - 8.17 = 55.49
so 3 Pounds since you took 8.17 three times to get 55.49

Tell whether (2, 5) is a solution of the equation y = 2x + 1. Show your work. I’LL PUT YOU AS BRAINLIEST
Answer:
The solution of (2,5) indeed equals the solution of the equation y=2x+1
Step-by-step explanation:
to solve just plug in the values.
y=2(2)+1 which gives us the y value of y=5
to solve for x, plug in y. 5=2x+1.
subtract 1 from both sides, and you get 4=2x
then divide 2 on both sides to get x, which is 2. therefore this is true.

A fish population that started at 250 has begun to decrease by 12 percent each week. Which equation below could be used to model this situation?
P=250(0.12)x
B
P=250(0.88)x
C
P=12(250)x
D
P=−250(0.12)x
250 - 250 * 12% = 250 * (1 - 12%) = 250 * 0,88
with x = fish number
=> P = 250 * 0,88 * x
Answer: A. P=250(0.12)x
Step-by-step explanation:
12%= 0.12
250 x 0.12 = the amount decreased by each week

A triangle has two sides of length 11 and 12. What is the smallest possible whole-number length for the third side? NO LINKS
Answer: The answer would be 16.
Step-by-step explanation:
[tex]a^{2} +b^{2} =c^{2} \\11^2+12^2=c^2\\121+144=c^{2} \\\sqrt{265} =\sqrt{c^2} \\c=16.27\\c=16[/tex]
16 is the smallest possible whole number for the length of the third side. By using the Pythagorean Theorem, we are able to find the third side.

In a class of 28 students, 15 earned an A on the final exam, 10 earned an A for the entire course, and 7 earned an A for both final exam and the entire course. What is the probability that a randomly selected student in this class did not earn an A on the final exam and did not earn an A for the entire course?
Using it's concept, it is found that there is a 0.3482 = 34.82% probability that a randomly selected student in this class did not earn an A on the final exam and did not earn an A for the entire course.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, we have that 13 out of 28 students did not earn an A on the final course, and 21 out of 28 students did not earn an A for the entire course, hence:
[tex]p = \frac{13}{28} \times \frac{21}{28} = 0.3482[/tex]
0.3482 = 34.82% probability that a randomly selected student in this class did not earn an A on the final exam and did not earn an A for the entire course.
