Answer:
the surface area of a penny = 662.81 mm²
Step-by-step explanation:
given:
A penny is a cylinder with a diameter of 19.05 millimeters
and a thickness of 1.55 millimeters.
find:
what is the surface area of a penny?
surface area of a cylinder formula:
As = 2 π r h + 2 π r²
let r = 19.05 / 2
r = 9.53 mm
let h = 1.55mm
plugin values into the formula:
As = 2 π (9.53) 1.55 + 2 π (9.53)²
As = 92.76 + 570.05
As = 662.81 mm²
therefore,
the surface area of a penny = 662.81 mm²
Answer:
the surface area of a penny = 662.81 mm²

When Emmett began his science experiment, he has 20 millimeters of an unknown solution. During the experiment, the change in the volume of the solution was -9 milliliters. What was his final volume of the solution.
To solve the problem, dakota added 20+( -9 ) and came up with an answer of -11 milliliters. Is Dakota correct? Why or why not ?
A : yes, dakota is correct
B: No. The answer should have been 11 milliliters, not -11 milliliters, because the volume should not be negative
C: No. Dakota should have subtracted 20 - (-9) because the volume decreased
Answer:
no the answer should be 11

Answer:
see the attachment
Step-by-step explanation:
Each point is moved 4 units up and 5 units right, as required by the problem statement.
Coordinates are positive in the "up" and "right" directions, so we take "4 units vertically" to mean +4 units, or 4 units up. Likewise, we take "5 units horizontally" to mean +5 units, or 5 units to the right.

Step-by-step explanation:
Hey there!
Here,
[tex] = - 6 + ( - 4) + 3 [/tex]
While working with them remember some rules;
(-) + (-) = sign (-) but add them.(+) + (+) = sign (+) and add.(+) - (+) = subtract but keep sign of greator number. (-) -(-) = subtract and keep the sign of greator number.Likewise in your question,
[tex] = - 6 - 4 + 3[/tex]
[tex] = - 10 + 3[/tex]
[tex] = - 7[/tex]

G(x)=\sqrt{x+3}g(x)= x+3 g, left parenthesis, x, right parenthesis, equals, square root of, x, plus, 3, end square root What is the domain of g?G?
Answer:
The domain of g(x) is -3 to infinity
Step-by-step explanation:
Given
[tex]g(x) = \sqrt{x + 3}[/tex]
Required
Determine the domain of g(x)
We start by expressing the content of the square root in the following form:
[tex]x + 3 \geq 0[/tex]
Subtract 3 from both sides
[tex]x + 3 -3 \geq 0 - 3[/tex]
[tex]x \geq 0 - 3[/tex]
[tex]x \geq - 3[/tex]
This can be expressed using interval notation as follows:
[tex]\{x: -3, infiniti\}[/tex]
Hence, the domain of g(x) is -3 to infinity

If ∠ABD and ∠CBD are a linear pair, m∠ABD = (3x+31)°, m∠CBD = (2x-6)°, then find m∠ABD. *
Answer:
∠ ABD = 124°
Step-by-step explanation:
A linear pair of angles sum to 180°, thus
∠ ABD + ∠ CBD = 180 , substitute values
3x + 31 + 2x - 6 = 180, that is
5x + 25 = 180 ( subtract 25 from both sides )
5x = 155 ( divide both sides by 5 )
x = 31
Thus
∠ ABD = 3x + 31 = 3(31) + 31 = 93 + 31 = 124°

Answer:
36
Step-by-step explanation:
First of all, the area of a circle is always pi(r)^2, which we can then substitute values. We will get pi(10)^2, and once we simplify that, we get 100pi as the area. Since we know that the area of the shaded sector is 10 pi, we can divide 10pi by 100pi to get 1/10. 1/10 is the area of the shaded sector compared to the area of the whole circle. Multiply 1/10 by the angle measure of a circle, which is 360, to get 36 degrees.

36
