1). What is the perimeter of the triangle?
с
5 mm
12 mm

Answers

Answer 1

Answer:

30

Explanation:

To begin, first find the length of the third side of the triangle. We are given that the two short sides of the triangle have lengths of 5 and 12. Use the Pythagorean Theorem to find the length of the third side:

a2+b2=c2,

where a and b represent the two shorter sides of the triangle, and c is the hypotenuse:

a2+b2=c2

52+122=c2

25+144=c2

169=c2

169−−−√=c2−−√

c=13

Now that we have the lengths of all three sides, add them together to find the perimeter:

5+12+13=30

The perimeter of the triangle is 30.

Answer:

c) [tex]h(t)=-16(t-1.5)^{2}+676[/tex]

Step-by-step explanation:

Each of the given equations is written in vertex form. This means that the vertex is written in the equation. The quadratic term (the term to the second degree), contains (x), and a value that is either added or subtracted to it. The additive inverse (meaning a number times negative one) of that number is the x-coordinate of the vertex. Therefore, the term inside the parenthesis is (-1.5). The constant is the y-coordinate of the vertex, and therefore it is 676. Since the object is being thrown off a cliff, gravity acts on it. The gravitational constant in feet per second is (-16), hence the coefficient of the quadratic term is (-16).

What is the slope of the line?

Answers

Answer: Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m.

Step-by-step explanation:

Answer:

slope = [tex]\frac{7}{4}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, - 3) and (x₂, y₂ ) = (3, 4) ← 2 points on the line

m = [tex]\frac{4-(-3)}{3-(-1)}[/tex] = [tex]\frac{4+3}{3+1}[/tex] = [tex]\frac{7}{4}[/tex]

12 1/2 − 9 1/4
This problem comes from subtract mixed numbers
5 3/4 - 2 5/12
7 1/5 - 3 7/10
11 2/3 - 8 1/2

Answers

To convert a mixed number to an improper fraction, multiply the denominator by the whole number out front, then add the numerator. Keep the denominator. For example:

12 1/2 = 2 * 12 + 1 = 25/2
9 1/4 = 4 * 9 + 1 = 37/4

Multiply 25/2 by 2/2 to have a common denominator:
25/2 * 2/2 = 50/4

50/4 - 37/4 = 13/4 or 4 1/3

Aylin went to the store to buy some new folders for school . She bought a total of 7 folders and spent a total of $12. She bought two different types of folders. Plain folders that cost $1 each and folders with cartoons that cost $2 each. How many did each type of folder did Aylin buy?

Answers

Answer:

2 plain folders and 7 folders with cartoons

Step-by-step explanation:

Given data

Let the number of plain folders be x

and the number of folders with cartoons  be y

x+y=7------------1

x+2y=12----------2

from 1

x= 7-y

put this in 2

7-y+2y=12

7+y= 12

y= 12-7

y=5

Put y=5 in 1

x+5= 7

x= 7-5

x= 2

Hence Ayin bought 2 plain folders and 7 folders with cartoons

< F would be 140 degrees

Step-by-step explanation:

So what you would do is that since they told you angle D is 40 degrees and you know that the 2 lines in there are parallel, and since they are asking for angle F, whne you add angle F and angle H they should equal 180 degrees which you know so you just subtract 40 degrees from 180 and you  get 140 degrees which if angle F and you can subtract 40 since angle H and angle D would be congruent.

Document #2. Justinians AccomplishmentsAt the core of Justinians goals as a leader was reestablishing the greatness of the Roman empire. He sought to do this in three ways. First, he engaged in several battles to recapture (take over) the land lost to barbarian invaders during the decline of the Roman empire. Second, rebuilding the capital city of Constantinople after the riots and fires of 532 CE. Third, and most memorable is the drafting of Justinians Code. Justinian set up a commission to collect and revise all of the Roman laws. In 529 CE, Justinian published the first set of laws known as the Body of Civil Law of Justinians Code. The code included laws on marriage, slavery, property ownership, womens rights, and criminal justice. Also included was an outline of the law and a collection of Justinians own new laws. Justinian used the law to unify his empire under his control and provide a sense of stability for his people. Justinians Code did not only have an effect of the Byzantine empire.
