The value of x in the figure is 21.4
How to solve for x?To do this, we make use of the following law of sine
[tex]\frac{\sin (A)}{a} = \frac{\sin (B)}{b}[/tex]
Using the values in the question, we have:
[tex]\frac{\sin (x)}{12} = \frac{\sin (42)}{22}[/tex]
Multiply both sides by 12
[tex]\sin (x) = \frac{12\sin (42)}{22}[/tex]
Evaluate the quotient
[tex]\sin (x) = 0.3650[/tex]
Take the arc sine of both sides
x = 21.4
Hence, the value of x is 21.4

Answer:
745.31
Step-by-step explanation:
1. 12.5^2 * 2 = 312.5
2. (3,14 * 156,25)/2 = 245.31
3. (30 * 12.5)/2 = 187.5
4. 187.5 + 245.31 + 312.5 = 745.31
Answer:
[tex]745.45 mm^{2}[/tex]
Step-by-step explanation:
(semicircle) A1 = 245.45 mm
(rectangle) A2 = 312.5 mm
(triangle) A3 = 187.5 mm
Formula for semicircle = [tex]A = \frac{1}{2} \pi r^{2}[/tex]
[tex]\frac{1}{2}\pi 12.5^{2} = 78.13\pi = 245.45 mm[/tex]
Formula for rectangle = [tex]A = lw[/tex]
[tex]25 x 12.5 = 312.5 mm[/tex]
Formula for triangle = [tex]A = \frac{1}{2} bh[/tex]
[tex]\frac{1}{2} 30(12.5) = 187.50mm[/tex]
Now we add them all up to get our answer
[tex]245.45 + 312.5 + 187.5 =745.45mm^{2}[/tex]

Help a formula word problem. Thank you if you help. You're a genuis!

==========================================================
Explanation:
We start with one block at the very left side. This is algebraically written as [tex]a_1 = 1[/tex]. The small subscript '1' means we're dealing with the first term, and that is set equal to 1. In other words, the first term is 1.
The second term is three since we have three blocks as the next figure down the line. So [tex]a_2 = 3[/tex]. We can then see that [tex]a_3 = 6[/tex] and [tex]a_4 = 10[/tex]
The sequence of the first four terms are: 1, 3, 6, 10.
The notation [tex]a_n = a_{n-1} + n[/tex] tells us "to get the nth term [tex]a_n[/tex], we add the previous term ([tex]a_{n-1}[/tex]) to the value of n".
For example, if we wanted the third term, we would add the second term a2 onto the value of n = 2. In order to know a2, we need the diagram or you would have to use the recursive formula to find it.
Furthermore, it means that to find the fifth term [tex]a_5[/tex], we do the following
[tex]a_n = a_{n-1} + n\\\\a_5 = a_{5-1} + 5\\\\a_5 = a_{4} + 5\\\\a_5 = 10+5\\\\a_5 = 15[/tex]
The fifth figure will have 15 small little blocks to it. You can draw this out by copying the fourth figure, and then adding 5 smaller blocks to the very bottom portion. The sixth figure is basically a copy of the fifth one, but we have six little blocks along the bottom. This is the "plus n" being applied in the recursive formula.
So the 6th figure will have 15+6 = 21 blocks in total while the 7th figure has 21+7 = 28 blocks. This points us to choice (3).
Side note: These are known as triangular numbers. Note how the gaps between consecutive values of 1,3,6,10,15,21,28 is +2,+3,+4,+5,+6,+7.

MODELING WITH SYSTEMS OF INEQUALITIES
There are many situations that arise in business and engineering that necessitate systems of linear inequalities. The region in the xy-plane that solves the systems often represents all of the viable solutions to the system, so being able to visualize this region can be extremely helpful. As always, with modeling, it is important to really read the problems and understand the physical quantities involved.
(a) If John works 14 hours mowing and 30 hours at the bakery, does this satisfy all of the problem’s constraints?
(b) If x represents the hours John spends mowing and y represents the hours he spends at the bakery, write a system of inequalities that describes this scenario.
Answers
The question is incomplete. The complete question is :
John mows yards for his father's landscaping business for $ 10 per hour and also at a bakery for $ 15 per hour. He can work at most 52 hours per weak during the summer. He needs to make at least $ 600 per week to cover his living expenses.
a) If John works 14 hours mowing and 30 hours at the bakery, does this satisfy all of the problem’s constraints?
(b) If x represents the hours John spends mowing and y represents the hours he spends at the bakery, write a system of inequalities that describes this scenario.
Answer:
a). No
b). 10x + 15y ≥ 600
Step-by-step explanation:
a). Number of hours John works mowing = 14 hours
Number of hours John works at bakery = 30 hours
Therefore, according tot he question,
= 14($10) + 30($15)
= 140 + 450
= $ 590
This is not enough money. He needs to earn $ 600 per week.
b). Given :
x = hours John spends mowing
y = hours John spends at the bakery
Therefore, the inequalities which describes this situation is:
x + y ≤ 52
10x + 15y ≥ 600
