Answer:
∠A = 44°
Step-by-step explanation:
In order to find the measure of angle A, you need to know the value of the variable x. This means you need some relation that you can solve to find x.
Happily, that relation is "the sum of angles in a triangle is 180°." This means ...
84° +(x +59)° +(x +51)° = 180°
(2x + 194)° = 180° . . . collect terms
2x = -14 . . . . . . . . . . divide by °, and subtract 194
x = -7 . . . . . . . . . . . .divide by 2
Now, the measure of angle A is ...
∠A = (x +51)° = (-7 +51)°
∠A = 44°

Write and inequality to compare the fractions. 24/18 and 25/15
Answer:
25/15 > 24/18
Step-by-step explanation: Both of these fractions can be reduced so that the denominator is 3. This will make it much easier to compare the two fractions. For 24/18, if you divide both the numerator and the denominator by 6, then the fraction simplifies to 4/3. For 25/15, if you divide the numerator and denominator by 5, then the fraction simplifies to 5/3. Since these fractions have a common denominator, the fraction with the larger numerator is going to be the larger fraction. So, 25/15 is greater than 24/18.

How will the solution of the system y > 2x + Two-thirds and y < 2x + One-third change if the inequality sign on both inequalities is reversed to y < 2x + Two-thirds and
y > 2x + One-third?
Answer:
There is no solution to the system in its original form. There are no points in common. If the signs are reversed, the system has an intersection with an infinite number of solutions.

What is percentage?A percentage, often known as percent, is a division by 100. Percentage, which means "per 100," designates a portion of a total sum. 45 out of 100 is represented by 45%, for instance. Finding the percentage of a whole in terms of 100 is what percentage calculation is. Both manual calculation and the use of internet calculators are options.
Given:
Sharon's pay = $30000,
Raise percentage = 10%,
Samantha pays = $40000,
Raise by = $1000,
Calculate Sharon's pay as shown below,
Sharon's pay = 30000(1 + 0.10)⁴
Sharon's pay = 30000 × 1.77
Sharon's pay = $43923
Calculate pay of Samantha after 4 years,
The pay of Samantha = 40000 + 4 × 1000
The pay of Samantha = $44000
Thus, Sharon's annual salary first exceeds Samantha's after 4 years.

2. rx + h = -k
solve for x?
Answer:
x=(-k-h)/r
Step-by-step explanation:
rx+h=-k
subtract h from both sides.
rx=-k-h
divide both sides by r.
x=(-k-h)/r

Use polar coordinates to find the volume of the given solid.
Below the plane
2x + y + z = 4
and above the disk
x2 + y2 ≤ 1
Using polar/cylindrical coordinates, we take
x = r cos(t )
y = r sin(t )
z = z
so that
dV = dx dy dz = r dr dt dz
The solid is given by the set
D = {(x, y, z) : x ² + y ² ≤ 1 and 0 ≤ z ≤ 4 - 2x - y}
or in cylindrical coordinates,
D = {(r, t, z) : 0 ≤ r ≤ 1, 0 ≤ t ≤ 2π, and 0 ≤ z ≤ 4 - 2r cos(t ) - r sin(t )}
Then the volume of the solid is
[tex]\displaystyle \iiint_D \mathrm dV = \iiint_Dr\,\mathrm dr\,\mathrm dt\,\mathrm dz \\\\ = \int_0^{2\pi} \int_0^1 \int_0^{4-2r\cos(t)-r\sin(t)} r\,\mathrm dz\,\mathrm dr\,\mathrm d t \\\\ = \int_0^{2\pi}\int_0^1 (4r-2r^2\cos(t)-r^2\sin(t))\,\mathrm dr\,\mathrm dt \\\\ = \int_0^{2\pi} \left(2 - \frac23 \cos(t) - \frac13 \sin(t)\right) \,\mathrm dt \\\\ = \boxed{4\pi}[/tex]
The volume of the given solid below the plane 2x + y + z = 4 and above the disk x2 + y2 ≤ 1 is 4π.
What is the volume of the solid in polar coordinates?The volume of the solid in polar coordinates can be calculated by the double integral in polar coordinates.
[tex]V = \iint_R f(x,y) \,dA.\\[/tex]
Similarly, by polar coordinates,
x = r cost
y = r sint
z = z
we get, dV = dx dy dz = r dr dt dz
The solid is given
D = {(x, y, z) : x ² + y ² ≤ 1 and 0 ≤ z ≤ 4 - 2x - y}
or in polar coordinates,
D = {(r, t, z) : 0 ≤ r ≤ 1, 0 ≤ t ≤ 2π, and 0 ≤ z ≤ 4 - 2r cos(t ) - r sin(t )}
The volume of the solid is
[tex]\rm \int \int\int\ dV = \int \int\int\ rdr dt dz\\ \rm = \int\limits^{2\pi}_0\int\limits^1_0 \int\limits^{4-2rcost-rsint}_0 rdr dt dz\\\rm =\int\limits^{2\pi}_0\int\limits^1_0 {4r-2r^{2} cost-r^{2} sint} dr dt\\\rm =\int\limits^{2\pi}_0( 2-2/3cost-1/3sint) dt\\\rm =4\pi[/tex]
Hence, The volume of the given solid below the plane 2x + y + z = 4 and above the disk x2 + y2 ≤ 1 is 4π.

Wich number is written in the scientific notation
Answer:
c. 1.3452 x 10^4
Step-by-step explanation:
William Shakespeare wrote 37 plays, including tragedies, comedies , and histories. He wrote the same number of tragedies and histories, He wrote the same number of tragedies and histories , but the number of comedies he wrote is 3 less than twice the number of tragedies. Write the system of equation to find how many of each type of play did Shakespeare write.
Answer:
10 tragic and histories, and 1y comedies
Step-by-step explanation:
let X = the number of tragedies
let X = the number of histories
2x - 3 = the number of comedies
x + x + 2x - 3 = 37
4x = 40
x = 10
2x - 3 = 2(10) - 3 = 17 comedies.
