Answer:

b

Step-by-step explanation:

not exactly "impossible" my good lad

Answer:

B

Step-by-step explanation:

of course, the even fractions are not irrational.

sqrt 16 is not irrational bc =4

so the answer is B, or sqrt 15

Answer:

5/14

Step-by-step explanation:

To work this out, we simply need to divide 1 3/4 miles by 4 9/10 miles.

1 3/4 ÷ 4 9/10

Start by converting both terms to improper fractions:

(4/4 + 3/4) ÷ (40/10 + 9/10)

= 7/4 ÷ 49/10

To divide, we simply multiply by the reciprocal of the second fraction:

7/4 * 10/49

= 70 / 196

Now we can take out common factors of the 70 / 196

70 / 196

= (5 * 2 * 7) / (14 * 2 * 7)

= 5 / 14

So the straight section of the track is five fourteenths of the entire length.

Answer:

Answer:

It would be 160 (C)

Step-by-step explanation:

160 is the only one that works if u rplace x with 160.

Answer:

160

This is how I got my answer I divided each answer by 4 to see if it equaled 40 and 160 divided by 4 equals 40 so 160 is your answer

Answer:

39.7%

Step-by-step explanation:

(actual value - estimated value) / actual value

5.8 - 3.5 = 2.3

2.3 / 5.8 = 0.3965 = 39.65%

Answer:

Overall, across all grades and subjects, the average test question count is 10, the second favorite number of questions is 5. A major contributor in determining the question count for an assignment is its assessment type.

Hope I helped!! If I did please give brainliest because I cant level up without having 1 more ;(

Step-by-step explanation:

Answer: The break even point is when they have sold 16 books and have made $288

Step-by-step explanation:  The costs are modeled in the equation y = 12x + 96.  x is the number of books sold.

The earnings are modeled by he equation y = 18x.

Substitute 18x for y and solve for x.

18x = 12x + 96  Subtract 12x from both sides.

6x = 96 Divide both sides by 6

x = 16

Substitute into the original equations to solve  for y

y = 12(16) + 96

y = 192 + 96

Y = 288

y = 18(16)

y = 288

Answer:

C = 12n + 90

Step-by-step explanation:

Answer:

D. y = 0.8x + 9.25

Step-by-step explanation:

The pizza parlor charges a flat rate of 9.25, this means that the value 9.25 is constant. The value 0.8 is a coefficient, meaning that is relevance in the equation is to be multiplied by the x value.

Answer: 3 grams

Step-by-step explanation: Each distribution of food must be equal so divide food by amount of cats which is 3 to get 3

Mathmatically 9/3 = 3 grams

Answer:

10 flour

Step-by-step explanation:

          1:2

         5:x     all you have to do is multiply by 2, sense the ratio is 1:2, flour will always be 2 times greater than sugar. so the answer is 5 x 2 =10

Answer: I think its (B) Reflection over the x-axis

Step-by-step explanation: Hope this helps!

Answer:

reflection over the x axis

Step-by-step explanation:

because the line that there reflecting over is the x axis line thats left to right, not y axis which is up and down

hope that helps, have a great day :>

Answer:

The system is consistent; it has one solution ⇒ D

Step-by-step explanation:

A consistent system of equations has at least one solution

An inconsistent system has no solution

In the system of equations ax + by = c and dx + ey = f, if

In the given system of equations

∵ -2y + 2x = 3 ⇒ (1)

∵ -5y + 5x = 12 ⇒ (2)

→ By comparing equations (1) and (2)

∵ -2 ≠ -5

∵ 2 ≠ 5

∵ 3 ≠ 12

→ By using the 3rd rule above

∴ The system is consistent independent and has exactly one solution

∴ The system is consistent; it has one solution

Answer:

Please check the explanation.

Step-by-step explanation:

Thus, the domain of the first relation is: {-2, -1, 0, 2}

Thus, the range of the first relation is: {-4, -2, 2}

Given the second relation

x        y

-4      -2

-2       1

1         4  

4         4

Thus,

The domain of the second relation is: {-4, -2, 1, 4}

Thus,

The range of the second relation is: {-2, 1, 4, 4}

Answer:

The velocity of light, v, is the product of its wavelength, λ , and its frequency, f. This means that the wavelength is the velocity, v, divided by the frequency, f.

Wavelength of light = velocity of light / frequency of light

λ = v/f

λ = Wavelength of light, meters

v = Velocity of light (c = 3.0 x 108 m, for speed of light if not otherwise defined)

f = frequency of light, Hz

Step-by-step explanation:

Answer:

The answer is A.

Step-by-step explanation:

This is because the Triangle is being rotated counter clockwise 90 degrees, then reflected over the Y axis.

So, point (-6, 8) would become (-8, -6), and so forth.
