Answer:
x<−6
Step-by-step explanation:
Let's solve your inequality step-by-step.
−2.1x+2.9>15.5
Step 1: Subtract 2.9 from both sides.
−2.1x+2.9−2.9>15.5−2.9
−2.1x>12.6
Step 2: Divide both sides by -2.1.
−2.1x−2.1>12.6−2.1
x<−6

What is the perimeter of this triangle ?
Answer:
36 units
Step-by-step explanation:
The two legs of this right triangle are 9 and 12. In order to find the length of the hypotenuse, you must plug in the 9 and 12 to the Pythagorean theorem:
a^2 + b^2 = c^2, where a and b are legs and c is the hypotenuse
If you plug in the values 9 and 12, you get:
9^2 + 12^2 = c^2
= 81 + 144 = c^2
= 225 = c^2
= 15 = c
This means that the hypotenuse is 15 units long. Now, you just need to add all the sides to get:
9 + 12 + 15
= 36 units
(Also as a fun fact, a Pythagorean Triple is when the three sides of a right triangle are integers. It is good to memorize a few of these, like 3-4-5, 5-12-13, 7-24-25 and 8-15-17. The largest side value is always the hypotenuse, and if you multiply all the sides by a scale factor, you can get other triples. If you knew the 3-4-5 triple, you might have noticed that 9 and 12 are 3 times each of the legs 3 and 4. From that information, you could just multiply the 5 by 3 to get 15 for the hypotenuse of this triangle, which might've made this problem a little easier)

Help quick The engineers designing the All Aboard Railroad between Boca Raton and Jupiter decide to create parallel tracks through this portion of the railway. To illustrate their plans to the county commission, they use a coordinate plane. The southbound track will have an equation of 2x + 5y = 15. What is the equation of the parallel northbound track that runs through the point (4, – 2)?
A. 2x + 5y = −2
B. 2x − 5y = 18
C. 5x + 2y = 16
D. 5x − 2y = 24
Answer:
Step-by-step explanation:
The answers is A
The required equation of the parallel track that runs through the point (4 , -2) is 2x + 5y = −2.
The engineers designing the All Aboard Railroad between Boca Raton and Jupiter decided to create parallel tracks through this portion of the railway.The southbound track will have an equation of 2x + 5y = 15. What is the equation of the parallel northbound track that runs through the point (4, – 2) TO determine.
The equation is the relationship between variables and represented as y=ax + b is an example of a polynomial equation.
Equation of the southbound track,
2x + 5y = 15
slope of the above equation is m = -2/5
Since the slope of the parallel lines are equal.
The equation of the parallel northbound track that runs through the point (4, – 2),
(y + 2) = -2/5 (x - 4)
5(y + 2) = -2 (x-4)
5y + 10 = - 2x +8
2x + 5y = 8-10
2x + 5y = -2
Thus, the required equation of the parallel track that runs through the point (4 , -2) is 2x + 5y = −2.

Micah is shopping for work shirts. The short-sleeve shirts cost $18 each and the long-sleeve shirts cost $24 each. He wants to buy 2 more short-sleeve shirts than long-sleeve shirts, and he is willing to spend no more than $120 total. How many long-sleeve shirts can he buy?
Answer:
2
Step-by-step explanation:
18 + 18 = 36
36 + 24 = 60
60 + 18 = 78
78 + 24 = 102
102 + 18 = 120
There are two total long-sleeve shirts and four total short-sleeve shirts.

Artaud noticed that if he takes the opposite of his age and adds 44 he gets the number 31. How old is Artaud?
sin^2x + sin^2x + cos²x
Answer:
Answer:
A. 2 sinx cosx - 1 + 2 sin^2 x.
Step-by-step explanation:
sin2x = 2 sinx cosx
cos2x = cos^2x - sin^2x
So sin2x - cos2x = 2 sinx cosx - ( cos^2x - sin^2x)
But cos^2 x = 1 - sin^2 x, so we have:
2 sinx cosx - (1 - sin^2 x - sin^2x)
= 2 sinx cosx - 1 + 2 sin^2 x.

Liana has 320 yards of fencing to enclose a rectangular area. Find the dimensions of the rectangle that maximize the enclosed area. What is the maximum area? A rectangle that maximizes the enclosed area has a length of nothing yards and a width of nothing yards
Answer:
Breadth = 60, Length = 60
Step-by-step explanation
Let length & breadth of rectangular area be : L & B
As, Fencing Yards = 320. So, perimeter ie 2 (L + B) = 320
B = (320 - 2L)/2 → B = 160 - L (*)
Area of rectangle [A] = L x B = L (160 - L) → A = 160L - L^2
Maximising Area, So first derivative d [A] / d [L] = 160 - 2L
d [A] / d [L] ] = 0 → 160 - 2L = 0 → L = 160/2 → L = 80
By (*) : B = 160 - L = 160 - 80 → B = 80
Checking maximising condition, double derivative d^2[A] / d[L]^2 = -2
As d^2[A] / d[L]^2 is negative, L & B values are maximising A
Given these processes: 1. cartilage ossification 2. bony callus formation 3. hematoma formation 4. fibrocartilaginous callus formation 5. remodeIing of woven (spongy) bone into compact bone Which sequence best represents the order in which the processes occur during repair of a fracture?
Answer:
The sequence that best represents the order during repaid of a fracture as as
follows
3. hematoma formation
4. fibrocartilaginous callus formation
2. bony callus formation
1. cartilage ossification
5. remodeling of woven (spongy) bone into compact bone
Step-by-step explanation:
When a bone is fractured, the first step following a bone fracture is hematoma formation.
Hematoma formation is formed when a little blood escapes from the blood vessels and remains in the skin's thickness, creating a blue spot. The hematoma is an effusion of blood that occurs deeper under the skin.
From there, the formation of tissues begins from end to end of the broken bones. It is a reorganization of the bone tissue (the bone itself), allowing the consolidation of a fractured bone. This bone formation welds the two parts of the broken bone together for a particular period depending on the patient's bone tissue condition. This bone callus will form in two episodes.
1) There first appears a fibrocartilaginous callus, also called connective callus, which allows the fracture to heal in a few weeks. It is an immature bone.
2) In a second step, this immature bone is gradually replaced by another bone (calcified/bony) resembling the bone which has been fractured.
From there, the ossification of the callus occurs where the bony callus is further replaced by woven spongy bones to form a stronger stabilizing collar.
Finally, the remodeling of woven (spongy) bone into compact bone takes place. Lamellar bones are replacing these woven spongy bones.
You start at (4, 6). You move up 4 units and down 8 units. Where do you end?
Answer:
(4, 2)
Step-by-step explanation:
Translation in right or left causes the x coordinate to change while translation in up or down causes the y coordinate to change.
Moving left or down causes the coordinates to be going negative.
Moving right or up causes the coordinates to be positive.
Original point (4, 6)
Up 4 units:
(4, 6 + 4) = (4, 10)
Down 8 units:
(4, 10 - 8) = (4, 2)
You end up at point (4, 2)

Letter: 8.5 inches by 11 inches Legal: 8.5 inches by 14 inches Junior legal: 5 inches by 8 inches Tabloid: 11 inches by 17 inches a. Are any of the paper sizes similar? b. The dimensions of government-letter paper are each 0.5 inch less than the dimensions of letter paper. Are these paper sizes similar? Question 2 c. By increasing the shorter side of legal paper by inch, it is similar to the size of junior legal paper.
Answer
a. No none are similar.
b. No.
c. Even if it were to be increased it still won’t be similar as what we would get would be 133 inches.
Step-by-step explanation:
LETTER = 8.5inches * 11 inches = 93.5inches.
LEGAL = 8.5inches * 14 inches = 119 inches
Junior legal: 5 inches * 8 inches = 40inches.
Tabloid: 11 inches * 17 inches = 187 inches
Government paper = 8inches * 10.5 inches = 84 inches.
