Three students attempt to define what it means for lines lll and mmm to be perpendicular.

Can you match the teacher's comments to the definitions?

Answer:

A=1,3,5,15

B=1,3,5,7,9,11,13,15

C=3,6,9,12,15

U=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15

Answer:

Step-by-step explanation:

1/2 + b + h

Okay so we know that b is 6 and that h is 10 so we can change the question to this : 1/2 + 6 + 10. We know that 1/2 is also writen as 0.5 , now all you need to do is 0.5 + 6 + 10 = 16.5 . The question asks to round to the nearest 10th so you need to add a 0 after the 5 so you can round up or down.

16.50

Now you need to look at the 10th number which is 5 and to round it up you need to look at the number after that which would be 0, we know that anything that is 4 or below gets rounded down so your answer for this question is simply 16.5.

I hope that helped you and good luck!

Answer:

the answer is 12.6419214

Answer:

24 teaspoons of red paint would be needed.

Step-by-step explanation:

Given that the initial mixture contains 8 teaspoons of red paint and 12 teaspoons of blue paint, this mixture contains a total of 20 units of paint, of which 8 are red, that is, 8 out of 20. Therefore, the proportion of red paint is 40%, while the proportion of blue paint is 60% remaining.

Therefore, in the case of making the same mixture (with the same proportion) using 36 teaspoons of blue paint, the necessary amount of red paint is determined through the following calculation:

60 = 36

40 = X

((40 x 36) / 60) = X

1,440 = 60 = X

24 = X

Thus, 24 teaspoons of red paint would be needed.

Answer:

y = 69

Step-by-step explanation:

start with the distributive property:

5/9 * y and 5/9 * 3

and now you have: 5/9y + 15/9 = 40

and we have to isolate y so subtract 15/9 from both sides:

5/9y + 15/9 = 40

        - 15/9     -15/9

and now you have 5/9y = 345/9

and now divide both sides by 5/9 so: 5/9y divided by 5/9 = y

and 345/9 divided by 5/9 = 345/5 and lets simplify....

y= 69

hope this helps luv

Answer:

6042915 balls.

Step-by-step explanation:

Volume of a ping pong ball is;

V = (4/3)πr³

diameter of ping pong ball is given 4cm = 0.04 m

Radius; r = 0.04/2 = 0.02 m

V = (4/3)π(0.02³)

V = 0.00003351032 m³

Room is 9.5 meters long, 7.5 meters wide, and 3 meters high.

Volume; V = 9 × 7.5 × 3 = 202.5 m³

Number of ping pong balls that will fit into the room = volume of room/volume of ping pong balls = 202.5/0.00003351032 = 6042914.540956151

Approximately 6042915 balls.

Answer:

The acceleration is 2.9m/s^2

Step-by-step explanation:

Given

[tex]Initial\ Speed\ (u) = 6m/s[/tex]

[tex]Final\ Speed\ (v) = 35m/s[/tex]

[tex]Time\ (t) = 10s[/tex]

Required

Determine the acceleration

This question will be answered using Newton's first equation of motion.

[tex]v = u + at[/tex]

Substitute values for v, u and t

[tex]35 = 6 + 10 * a[/tex]

[tex]35 = 6 + 10 a[/tex]

Collect Like Terms

[tex]10a = 35-6[/tex]

[tex]10a = 29[/tex]

Solve for a

[tex]a = 29/10[/tex]

[tex]a = 2.9[/tex]

Hence, the acceleration is 2.9m/s^2

Step-by-step explanation:

The sample space of a random experiment is the collection of all possible outcomes. An event associated with a random experiment is a subset of the sample space. The probability of any outcome is a number between 0 and 1. The probabilities of all the outcomes add up to 1.

Answer:

C. [tex] \overline{GI} < \overline{GH} < \overline{HI} [/tex]

Step-by-step explanation:

In a triangle, the longest side is opposite to the largest measure of angle. The medium side is opposite to the medium angle, while the shortest side is opposite to the smallest angle.

In ∆GHI,

✍️m<G = 95°, it is opposite to [tex] \overline{HI} [/tex]

<G is the largest angle, therefore, [tex] \overline{HI} [/tex] is the longest side.

✍️m<I = 180 - (95 + 38) = 47°.

<I is opposite to [tex] \overline{GH} [/tex]

<I is the medium angle, therefore, [tex] \overline{GH} [/tex] is the medium side.

✍️m<H = 38°, it is opposite to [tex] \overline{GI} [/tex]

<h is the smallest angle, therefore, [tex] \overline{GI} [/tex] is the shortest side.

✅This means:

[tex] \overline{GI} < \overline{GH} < \overline{HI} [/tex]

Answer:

y = -[tex]\frac{2}{3}[/tex] x - 3

Step-by-step explanation:

The general form of the equation of the line (linear equation) is:

y = ax + b

The line passes through (-3, -1) and (6, -7), i.e:

(1) (x=-3, y=-1) is a point that verifies the equation of the line, and

(2) (x=6, y=-7) also verifies the equation.

So we can put up a system of 2 equations to obtain a and b:

y = ax + b

(1) -1 = a (-3) + b

(2) -7 = a (6) + b

______________

substracting (1) - (2) we can obtain a:

-1 - (-7) = a (-3-6) ⇒ 6 = -9 a  ⇒ a = -2/3

by replacing a in (1) we can obtain b:

-1 = -2/3 (-3) + b ⇒ -1 -2 = b ⇒ b = -3

so, the equation is:  y = ax + b ⇒ y = -2/3 x - 3

Verification: (2) giving x= 6, let's see if y=-7 is obtained:

y = -2/3 6 - 3 ⇒  y = -4 - 3 = 7 ⇒ RIGHT!

Step-by-step explanation:

Answer:

m<B = 62°

Step-by-step explanation:

Given that ∆ABC is congruent to ∆TUV, it follows that their corresponding angles are equal to each other. Therefore:

m<B = m<U

m<B = (3y + 2)°

m<U = (4y - 18)°

Thus,

3y + 2 = 4y - 18

Collect like terms

18 + 2 = 4y - 3y

20 = y

y = 20

m<B = (3y + 2)°

Plug in the value of x

m<B = 3(20) + 2

m<B = 60 + 2

m<B = 62°

Answer:

Yes

Answer:

K=5

Step-by-step explanation:

12k-15=35+2k

12k=50+2k

10k=50

k=5

Answer:

[tex]k = 5[/tex]

Step-by-step explanation:

[tex]12k - 15 = 35 + 2k[/tex]

Our goal is to isolate k

[tex]12k - 15 = 35 + 2k\\\;\;\;\;+15 \;\;\;\;\;\;\; +15[/tex]

[tex]12k = 50 + 2k\\-2k \;\;\;\;\;\;\;\; -2k[/tex]

[tex]10k = 50[/tex]

Now we have k isolated to one side. Our final step is to have k be just k, no coefficient. We can do this by dividing each side by the coefficient.

[tex]\large\frac{10k}{10} = \frac{50}{10} \\\\10k\;\div\;10 = k\\50\;\div\;10 = 5\\[/tex]

[tex]\large\boxed {k \;=\;5}[/tex]
