Lyla is playing a game in math class where the students describe a number they are thinking of and the class uses clues to determine which type of number it is. Lyla tells her class that she is thinking of a positive number with infinitely many nonrepeating digits after the decimal point. Which type of number is Lyla thinking of?Single choice.
(1 Point)

1. whole
2. integer
3. rational
4. irrational

Answer:

Step-by-step explanation:

Top/Bottom = 12

Sides = 15

Front/Back = 20

20 + 15 + 12 = 47

47 / 1/2 = 23.5

We will see that the axis of symmetry is x = 3, so the correct option is c.

The axis of symmetry is a line of the form x = a, such that it divides the parabola in two halves.

Particularly, the axis of symmetry passes through the vertex, so the x-value of the vertex is equal to the value of the axis.

Then we only need to find the x-value of the vertex, remember that for a quadratic:

[tex]y = a*x^2 + b*x + c[/tex]

The vertex is at:

[tex]x = -b/2a[/tex]

Then in our case, the vertex is at:

[tex]x = -12/(2*-2) = -12/-4 = 3[/tex]

So the axis of symmetry is x = 3, then the correct option is C.

The answer is 904.8 yd³

Step-by-step explanation:

The formula for a sphere's volume is 4/3πr²

r in this case is 12/2 which is 6. That means that r=6 which gives us 904.78 which is rounded to 904.8.

Answer:

904.32

Step-by-step explanation:

v= [tex]\frac{4}{3\\}[/tex][tex]\pi[/tex][tex]r^{3}[/tex]

first cube the radius (6)  (radius is half of the diameter 12)

6x6x6 = 216

multiply by pi

216 x 3.14 = 678.24

multiply by 4/3

[tex]\frac{678.24}{1}[/tex] x [tex]\frac{4}{3}[/tex] = [tex]\frac{2712.96}{3\\}[/tex] = 904.32

2x+5+4x-2+c=12x-1

6x+3+c=12x-1

6x+4+c=12x =>4+c=12x-6x =>4+c=6x => c=6x-4

Answer:

Yes, we can conclude that Triangle ABC is similar to triangle DEF because the measures of the 3 angles of both triangles are congruent.

Step-by-step explanation:

We have the measure of 2 angles from both triangles, and we know that triangles have 180°, so we can solve for the measure of the third angle for both triangles.

Triangle ABC:

Measure of angle A= 60°

Measure of angle C= 40°

Measure of angle B = 180°- (measure of angle A + measure of angle C) = 180° - (60° + 40°) = 80°

Triangle DEF

Measure of angle E= 80°

Measure of angle F= 40°

Measure of angle D= 180° - (measure of angle E + measure of angle F) = 180° - (80° + 40°) = 60°

The measures of the angles in Triangle ABC are: 60°, 40°, and 80°.

The measures of the angles in Triangle DEF are: 60°, 40°, and 80°.

Since the measure of 3 angles of the two triangles are the same, we know that the two triangles are similar.

Answer: 9,600

Step-by-step explanation:

I could possibly did wrong but I shall explain this none the less. I first knew that 10% of 16,000 was 1,600. So then I just timed that by four getting 6,400. I then did 16,000-6,400 getting $9,600. Sorry if I’m wrong

Answer:

$9600

Step-by-step explanation:

10% of 16,000 = 1600

1600*4= 6400

16,000-6,400

= 9600

Answer:

Step-by-step explanation:

- Since y = -1, we will substitute the y variable in the equation for -1.

 -1 = -5/2x + 4

- Take away 4 from both sides in order to find out what x equals so we can substitute it.

 5 = -5/2x

- turn it into a positive by multiplying each side by -1.

 -1(-5 = -5/2x) =

 5 = 5/2x

- Divide each side by 5.

 1 = 1/2x

- Multiple both sides by 2.

2 = x

- Substitute the variables.

x = 2

y = -1

-1 = -5/2(2) + 4

a) 2(a+b)

Step-by-step explanation:

the sum of 2 numbers (or more) is always addition

so the sum of a  and b would be (a+b)

then, 2 times of a and b;

2(a+b)

^the times sign between the bracket and the 2 isnt needed, whenever there is a bracket and a number next to it, it is automatically a multiplication.

Answer:

the first truck

Step-by-step explanation:

the cost difference between the first truck and the second truck = $160,000-$145,000 = $15,000

the difference of gas cost between the first truck and the second truck = $0.31 - $0.26= $0.05 per mile.

so,

I think, this is a very significant number of truck cost compared with gas cost

for the best deal, the first truck is the best choice.
