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?
Answers
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
Solve for x. Round to the nearest tenth, if necessary.
Answers
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

Tell whether (2, 5) is a solution of the equation y = 2x + 1. Show your work. I’LL PUT YOU AS BRAINLIEST
Answers
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
Answers
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
Answers
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]

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
