Answer:

La leche que sale del huevo

Answer:

In order to find the graph equation, we can use the points given:

(0,1) (-1,4) (1,-2)

(slope between (0,1) (1,-2): -3)

y = mx + b or y = -3x + 1

Answer: The answer choice on the left, AKA the first one.

Step-by-step explanation:

Answer:

the answer is 2197cm^3

Step-by-step explanton

to find the side we need to take a square root of 169 which is 13 and then we need to multiply 13 3 times to get the answer which is 2197 and we use cm ^3 for   volume of the cube

Answer:

8/17 is correct because cosine = adjacent/hypotenuse, and since angle A is theta, or the reference angle, the adjacent of A would be 8, and the hypotenuse is always across the right angle.

15/17 would be sine instead of cosine

Answer:

Answer:

Light is about 299,999,700 mps (meters per second) faster than sound in dry air.

Step-by-step explanation:

We know that the speed of light is about 3 × 10 ^ 8 meters per second and that the speed of sound in dry air is about 3 × 10 ^ 2 meters per second. We need to solve 3 × 10 ^ 8 minus 3 × 10 ^ 2.

3 × 10 ^ 8 - 3 × 10 ^ 2 =

300,000,000 - 300 = 299,999,700

Light is about 299,999,700 mps (meters per second) faster than sound in dry air.

Answer:

If b = 6 and c = 10, the value of an expression is 3.

Step-by-step explanation:

Given the expression

[tex]\frac{5b}{c}[/tex]

We have to evaluate the expression if b = 6 and c = 10.

Important Tip:

In order to evaluate the expression  [tex]\frac{5b}{c}[/tex], all we need to do is to substitute the value of b and c in the expression.

As the expression is

[tex]\frac{5b}{c}[/tex]

substitute b = 6 and c = 10 in the expression

[tex]\frac{5b}{c}=\frac{5\left(6\right)}{10}[/tex]

     [tex]=\frac{30}{10}[/tex]

      [tex]=3[/tex]       ∵ [tex]\frac{30}{10}=3[/tex]

Therefore, if b = 6 and c = 10, the value of an expression is 3.

I took the quick check

Answer:

40%

Step-by-step explanation:

So I mostly will focus on the jogging total hours because thats literally what it says lol. Anyways, here I used the percent equation, which is

___ is ___% of ___. Since the question is "what percent", we mark our blank percent part as x, and when I fill the equation in it will seem like this:

"20 is x% of 50 (total hours)". So, now I translate, and this means:

20=x50, or in other words, 20=50x. To get x alone we divide by 50, but we also do it for the 20. 20/50 is .4, but because it has to be a percent, we move the decimal 2 places to the right, which gives 40, and finally it becomes

40%.

Hope it helps

Answer:

40%

Step-by-step explanation:

(20 hours Jogging)/(50 hours Total) = 0.4

0.4 * 100 = 40
