Step-by-step explanation:
if a=120 degrees find the measures of b,c, and d
Answer:
<b=120°,<c=60° & <d=60°
Step-by-step explanation:
Here,
given that <a=120°
<a is vertically opposite to <b
We know,vertically oppposite angles are equal
So,<a=<b=120°
<a & <c lies on a straight angle.
So,<c=180°-120° (Sum of two angles on a straight angle is 180°)
<c=60°
Again,<c is vertically opposite to <d.
So,<d=60°.

Find the circumference of a circle whose diameter is 20 mm. *Plz explain your answer*
Answer:
The circumference is 62.8.
Step-by-step explanation:
Find the diameter (in this case, 20mm)Multiply the diameter by 3.14, or pi. (Pi can be a different number depending on the problem but 3.14 is the most used one)The product of the diameter multiplied by Pi is the circumference of the circle!lou thinks the expression 27x^3-64 factors to (3x-4) (9x^2+12x+16). is he correct? How can you check his work? Show all work to justify your thinking.
Answer:
Step-by-step explanation:
(a³ - b³) = (a - b) (a² + ab + b²)
27x³ - 64 = 3³x³ - 4³
= (3x)³ - 4³ {a = 3x & b= 4)
Substitute in the above formula.
= (3x -4)([3x]² + 3x*4 + 4²)
= (3x - 4)(9x² + 12x + 16)
The expression 27x^3-64 factors to (3x-4) (9x^2+12x+16).

Convert 4,700,000,000 from standard form to scientific notation. 470 × 107 47 × 108 4.7 × 109 478
Answer:
4.7 * 10 ^9
Step-by-step explanation:
4,700,000,000
Scientific notation is of the form
a * 10 ^b where a is a number between 1 and less than 10
Move the decimal so that it is a number between 1 and less than 10
4,700,000,000 becomes 4.700000000 and we moved the decimal 9 places to the left b is +9 ( positive because we moved to the left) We can drop the extraneous zeros
4.7 * 10 ^9

Step-by-step explanation:
Solve the right triangle. Side AB is 2.9, but I don't know how to find two missing angles with three sides and a 90-degree angle. Please explain your answer.
Angle A = 68 degrees
Angle B = 22 degrees
Side AB = 2.9 cm
The three values are approximate
=========================================================
Explanation:
a = BC = 2.7 and b = AC = 1.1 are the two legs of the right triangle.
Use the pythagorean theorem to find the length of the hypotenuse
a^2 + b^2 = c^2
2.7^2 + 1.1^2 = c^2
8.5 = c^2
c^2 = 8.5
c = sqrt(8.5)
c = 2.91547594742266
c = 2.9
The hypotenuse is c = AB = 2.9
--------------------
We then use trig ratios to find the two missing angles.
Let's say we ignore the hypotenuse and focus on the two legs of the triangle.
With respect to reference angle A, side BC is opposite and AC is adjacent
Use the tangent ratio to get
tan(angle) = opposite/adjacent
tan(A) = BC/AC
tan(A) = 2.7/1.1
tan(A) = 2.45454545454546
A = arctan(2.45454545454546)
A = 67.8336541779176
A = 68
Note: arctan is the same as inverse tangent or [tex]\tan^{-1}[/tex]. Make sure your calculator is in degree mode.
-------------------
Similarly,
tan(angle) = opposite/adjacent
tan(B) = AC/BC
tan(B) = 1.1/2.7
tan(B) = 0.4074074074074
B = arctan(0.4074074074074)
B = 22.166345822082
B = 22
Or you could use the value of A to get B = 90-A = 90-68 = 22. This works because A+B = 90 as we're working with a right triangle. In other words, A and B are complementary angles.
-------------------
In summary we found
A = 68
B = 22
AB = 2.9
Z= pi^3h, solve for h
Answer:
Z/ pi^3 = h

Z/ pi^3 = h
help please urgent!!!! 10 points
Answer:
[See Below]
Step-by-step explanation:
✦ First you need to know the area of a triangle:
✧ ½ x b x h
✦ Now write you formula out:
✧ ½ x 5 x 4
✦ Now just solve:
✧ 5 x 4 = 20
✧ 20 / ½ = 10
So it'd be 10 m²

Step-by-step explanation:
Negative numbers are numbers that are less than 0. The opposite of a positive number is negative, and the opposite of a negative number is positive. Since the opposite of 0 is 0 (which is neither positive nor negative), then 0 = 0.

Answer:
15.62 feet
Step-by-step explanation:
If the flagpole is 10ft tall and the shadow is 12ft long, and you need to find the distance from the top of the flagpole to the far end of the shadow, to get your answer, you must use the pythagorean theorum.
[tex]a^{2} + b^{2} = c^{2}[/tex]
let height of flagpole = a
let length of shadow = b
let distance between the two = c
[tex]10^{2} + 12^{2} = c^{2} \\100 + 144 = c^{2}\\244 = c^{2}\\\sqrt{244} = \sqrt{c^{2}} \\\sqrt{244} = c\\15.62 = c[/tex]
A real estate agent's base salary is 22,000 per year. The agent earns a 4% comission on total sales. How much must the agent sell to earn 60,000 in one year
Answer: 950,000
Step-by-step explanation:
base salary is 22,000
Target 60,000
60,000-22,000 =38,000 which is 4%
So 38,000/4 = 9,500 which is 1%
So 9,500 * 100 = 950,000 which is 100% total sale
So commission of 4% on 950,000 is 38,000
Therefore 38,000 + 22,000 = 60,000

If this trapezoid is moved through the
translation (x+3, y-2), what will the
coordinates of D' be?
After a translation (x+3, y-2) the coordinates of D' be (4, 0).
What is a trapezoid?An open, flat object with four straight sides and one pair of parallel sides is referred to as a trapezoid or trapezium.
A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases. The legs of a trapezium can also be parallel. The parallel sides may be vertical, horizontal, or angled.
The altitude is the measurement of the angle perpendicular to the parallel sides.
The area of a trapezoid is (1/2)×(sum of the two parallel sides)×height.
From the given figure of this trapezoid in a coordinate plane, the points of D is (1, 2).
Now, If this trapezoid is moved through the translation (x + 3, y - 2) the coordinates of D' will be (1 + 3, 2 - 0) ⇒ (4, 0).
