Question 7 of 10 Classify the following triangle. Check all that apply. 6 D A. Scalene D B. Right C. Obtuse D. Isosceles E. Acute F. Equilateral​

The midpoint for any segment/line when you're given the start and end point of the line as A=(x1,y1) and B=(x2,y2) is

(   ((x1 + x2) /2), ((y1 + y2)/2)   )

So here the point is

(  (-2+6)/2), (-6+12)/2)  )

= (2, 3)

So it's the second option

Answer:

Find length opposite to 30deg

Opposite = tan(30)*42

= 24.2

Whole side = 24.2+10

Find angle of 0 + 30deg: (say x)

Tan(x) = 33.2/42

Arctan(0.79) = x

x = 38.3

The angle to find:

38.3-30:

8.3

The angle is 8.3deg.

Answer:

2.24

Step-by-step explanation:

the total surface area=

(3+10+5+10+6)×(20) + (2×3×24) + (2×½×(14+10)×3)

= 680 + 144 + 72

= 896 ft²

the paint will be needed at least :

896/400 × 1 gallon = 2.24 gallons

Step-by-step explanation:

y = 3 is not possible because when 3 is submitted in for y in the first equation the value for x + z is not 20.

Answer: [tex]\dfrac{15}{64}[/tex]

Step-by-step explanation:

Given

Inside radius of figure [tex]r_1=\frac{14}{2}=7\ ft[/tex]

Outside radius of figure [tex]r_2=\frac{16}{2}=8\ ft[/tex]

Area of outside region is [tex]A_1=\pi (8^2)[/tex]

Area of inside region [tex]A_2=\pi (7)^2[/tex]

Area of shaded region [tex]A_1-A_2[/tex]

Probability that point lies inside the shaded region is

[tex]\Rightarrow P=\dfrac{A_1-A_2}{A_1}\\\\\Rightarrow P=\dfrac{\pi (8^2-7^2)}{\pi 8^2}\\\\\Rightarrow P=\dfrac{64-49}{64}\\\\\Rightarrow P=\dfrac{15}{64}[/tex]

Answer:

x=4

Step-by-step explanation:

4x+16-x=28

4x-x+16=28

3x+16=28

3x=28-16

3x=12

x=12/3

x=4

Answer:

(B) Parallel to x-axis

Step-by-step explanation:

y = 7

This is a constant line, in which the value of y is always of 7, no matter the value of x.

In a line in which the value of y is constant, this line is parallel to the x-axis, so the correct answer to this question is given by option b.

Answer:

2 + 0.0 + 0.07 + 0.003

Step-by-step explanation:

Pretty much just adding the whole number and decimal.

2 (whole number) + 0.073

Expanded forms require showing which place the numbers are in (i.e. 0.07 is the hundredths place)

Answer:

18

Step-by-step explanation:

First, we know that the total is equal to 100%. We then know that 14 students make up 43.75%, and eight grade students make up the rest, at 100-43.75=56.25%.

One way we can figure this out to find how many students make up each percent. To find this, we can simply divide the number of students (14) by their percent (43.75) to get 14 students/43.75 percent = 0.32 students per percent. We can then multiply this by 56.25 to get 18 as our answer for the number of eight graders.

Answer: 18

Step-by-step explanation:

14/43.75% = 0.32

56.25 × 0.32 = 18

Therefore, 18 is the answer to this equation.

Answer:

so to do this we basicely just go through and substitute the anser in and see if it works.

Step-by-step explanation:

Circumference Formula: 2πr or dπ ⇒ r=radius and d=diamater

1.) π≈3.14

2.) 24×3.14=75.36

Answer:

40 % increase

Step-by-step explanation:

New price - original price

42-30 = 12

Divide by original price

12/30 = .4

Change to a percent

.4 * 100

40%

40 % increase

Answer:

x = 2 2/3

Step-by-step explanation:

6(x - 2) = 4

Distribute

6x - 12 = 4

Add 12 to each side

6x-12+12 = 4+12

6x = 16

Divide by 6

6x/6 = 16/6

x = 8/3

x = 2 2/3

We know that,

➪ ∠ ABC + ∠ BAC + ∠ BCA = 180°

➪ 81° + a° + 62° = 180°

➪ a° + 143° = 180°

➪ a° = 180° - 143°

➪ a° = 37°

Therefore, the measure of a is 37°.

Now, the three angles of the triangle are 81°, 37° and 62°.
