Answer:

540 jumps in 9 minutes.

Step-by-step explanation:

60 jumps a minute. Chen is fast, but we need to find how many jumps in 9 minutes.

Let's say one minute is m

m = 60

9m = 60x9

We do x9 because from m to 9m you need to multiply by 9, so lets do that on both sides.

9m = 540

9 minutes = 540 jumps

Hope this helps!

Answer:

Step-by-step explanation:

(x - 2)(x + 4)

=x(x + 4) -2(x + 4)

=x^2 + 4x - 2x - 8

=x^2 + 2x - 8

(x + 1)(x + 6)

=x(x + 6) +1(x + 6)

=x^2 + 6x + x + 6

=x^2 + 7x + 6

(x - 4)(x + 2)

=x(x + 2) -4(x + 2)

=x^2 + 2x - 4x - 8

=x^2 - 2x - 8

(x + 5)(x - 3)

=x(x - 3) +5(x - 3)

=x^2 - 3x + 5x - 15

=x^2 + 2x - 15

(x - 6)(x - 2)

=x(x - 2) -6(x - 2)

=x^2 - 2x - 6x + 12

=x^2 - 8x + 12

Answer:

x = 5.1

Step-by-step explanation.

Our first step is to find all the angles. If b = 91 degree and c is 38, a. has to be 51 because all triangles add up to 180 degree. Because we have both B and b, we can use sine law.

a/A     13/sin91      c/38

we can use b in this situation.

The legnth  of a is 10.1.

So,  x-5 would be 5.1

Answer:

1695.6 cubic feet

Step-by-step explanation:

Given that,

The corn fills 25% of the height of the silo.

The diameter of silo, d = 12 feet

Radius, r = 6 feet

Height, h = 60 feet

The volume of the part of the silo that is filled with corn is given by :

[tex]V=25\%\ of\ \pi r^2 h\\\\=\dfrac{25}{100}\times 3.14\times 6^2\times 60\\\\V= $$1695.6\ feet^3[/tex]

Answer:

52b

Step-by-step explanation:

She has 52 cards per deck, and b decks.

This means she has 52b cards.

How this works:

For 1 deck, she has 52 cards, or 52×1 cards.

For 2 decks, she has 104 cards, or 52×1 cards.

For 5 decks, she has 260 cards, or 52×5 cards.

For 10 decks, she has 520 cards, or 52×10 cards.

Therefore, for b decks, she has 52×b, or 52b cards.

Answer:

36 unit

Step-by-step explanation:

The number of unit cubes in the shape = 36 unit cubes

The dimension (volume) of each cubes = 1 unit³

The type of shape = 3-dimensional

The arrangement of the cubes in the shape = Without gaps

The volume of a 3-dimensional shape made of a number of unit cubes without gaps is equal to the sum of the unit cubes

Therefore;

The volume of the 3-dimensional shape that consists of 36 unit cube, V = (1 + 1 + 1 +...+ 1) unit³ = 36 unit³

The volume of the 3-dimensional shap³e, V = 36 unit³

Answer:

8/27

Step-by-step explanation:

First, we figure out how many students chose each school activity, so that we can find the probability of a student at random choosing running by putting (total running students)/(all students).

39 students chose tennis, as stated in the problem.

37 students chose football, as stated in the problem.

The total number of students who chose running must therefore be the the students who chose tennis and football, subtracted from the total number of students. 108 - 39 - 37 = 32, so 32 students chose running.

Therefore, the probability that a student at random chose running would be 32/108 or 8/27.

Answer:

Step-by-step explanation:

using pythagoras theorem

a^2 + b^2 = c^2

here 4 and 9 are the legs of the right angled triangle so let them be a and b respectively . third side is the hypotenuse because it is opposite to 90 degree so let it be c.

4^2 + 9^2 = c^2

16 + 81 = c^2

97 = c^2

Answer:

  a.  f(x) = (4x +5)(x -3)

  b.  x-intercepts: {-1.25, +3}

  c.  f(x) goes to +infinity as x goes to ±infinity

  d. plot the x-intercepts, the vertex, and a few other points; draw a smooth curve through them

Step-by-step explanation:

a. Here, you're looking for factors of (4)(-15) = -60 that have a sum of -7. Those factors will be -12 and +5, so we can factor the function as ...

  f(x) = (4x -12)(4x +5)/4

  f(x) = (x -3)(4x +5)

__

b. The x-intercepts are the values of x that make the factors zero:

  x -3 = 0   ⇒   x = 3 . . . . (add 3)

  4x +5 = 0   ⇒   x = -5/4 . . . . (add -5, divide by 4)

__

c. As with all even-degree polynomials with positive leading coefficients, the end behavior of f(x) matches that of |x|:

  as x → ∞, f(x) → ∞

  as x → -∞, f(x) → ∞

__

d. The vertex of the function will be located halfway between the x-intercepts, at x = (3-5/4)/2 = (7/4)/2 = 7/8. The value of f(x) there is ...

  f(7/8) = (4(7/8) +5)(7/8 -3) = -289/16 = -18.0625

Since the leading coefficient is 4, the normal x^2 function behavior is stretched vertically by a factor of 4. So, additional points would be

  x = 7/8 ±1, f(x) = -18.0625 +4·1 = -14.0625

  x = 7/8 ±2, f(x) = -18.0625 +4·2^2 = -2.0625

The answers of part B locate two points on the graph, and help find the vertex. The answer of part C confirms the graph as opening upward.

Step-by-step explanation:

Here we are given that C is between A and B.

Hope that helps

Answer:

AC Or CA

Step-by-step explanation:

So, this is what a b and c would look like on a number line:

A----C----B

However, we dont know exactly what these variables are. THey could be somerthing like this:

A------------------C-B

But this doesnt matter.

If we look at the first numberline, A and C make up the first half of the numberline.

C to B make up the later half.

AB is the total numberline.

SO tecnically, A to C+ C to B = AB

Or:

AC + CB = AB

This can also be seen in the second numberline.

A to C make up almost all of the numberline.

C to B make up a smll amount.

But in the end, AC + CB will still make AB.

Hope this helps you! :D

The phrases best describes the line that passes through the points (5, -7) and (a, -4) is rise from left to right.

Coordinates are two numbers (Cartesian coordinates), or sometimes a letter and a number, that locate a specific point on a grid, known as a coordinate plane. A coordinate plane has four quadrants and two axes: the x axis (horizontal) and y axis

As, we locate this coordinate in graph we can see the line will either rise from left to right or falls from right to left.

Hence, line that passes through the points (5, -7) and (a, -4) will rise from left to right.

Answer:

6

Step-by-step explanation:

The worst scenario is that of a slight possibility, the first 5 balls you took are completely different color. The chance of this happening is tiny, but if you want to be sure, then you should consider about it.

But, after taking out the sixth ball, you can be sure that the ball, now right on your hand, must share a same color with at least one of the balls you took out, since there are only five colors.

the answer to the question is 10

Answer:

d(x)  =  - 2666.67*a  +  42000

Step-by-step explanation:

Vamos a llamar a d(x) la ecuación de la demanda de CD, entonces como la relación entre las dos variables es lineal la ecuación de la demanda es del tipo:

d(x) = a*x  + b        (1)

en esa relación a es la pendiente de la recta y b es el intercepto con el eje y que en este cas es el eje de valores de d(x).

Tenemos dos condiciones que cumplir y dos incógnitas que determinar ( a y b).

Cuando el precio ( x = 18 $ ) el monto de d(x)  es de 10000 entonces por sustitución en la ecuación general (1)

10000 = 18*a  +  b   (2)

Y cuando   (  x  =  12  $) d(x) =  26000

26000 = 12*a  +b    (3)

Resolviendo para a y b el sistema de dos ecuacions con dos incógnitas tenemos:

restando  ec 3  -  ec 2

16000 =  - 6*a

de donde   a = - 16000/6

a =  - 2666.67

Llevando ese valor a ec 2

10000  =  12 *(- 2666.67) + b

10000 + 32000 = b

b  = 42000

Finalmente la ecuación buscada es:

d(x)  =  - 2666.67*a  +  42000

Como la pendiente es negativa significa que d(x) va decreciendo cuando x va en aumento
