Answer:

9:15 or 3:5

Step-by-step explanation:

A ratio can compare a part of a whole to a whole.

In this case, our whole is the total number of shots attempted: 15.

The basketball player successfully made 9 of the attempts. 9 is our other number in this ratio.

Put these values in a ration.

part:whole

9:15

Notice that 9 and 15 can be simplified by dividing both numbers by 3.

3:5

This is your simplified ratio.

Hope this helps!

Answer:

It should be [tex]15*10^{4}[/tex].

Step-by-step explanation:

[tex]300=3*10^{2}\\500=5*10^{2}\\\\300*500=(3*10^{2})*(5*10^{2})=(3*5)*10^{(2+2)}=15*10^{4}=1.5*10^{5}[/tex]

Answer: 1.5 x 10^5

Step-by-step explanation:

The first step is to re-arrange the factors like this :

5 x 3 x 10^2 x 10^2

Since

5 x 3 = 15

and the index law

10^a x 10^b = 10^a + ^b

gives us

10^2 x 10^2 = 10^2 + ^2 = 10^4

then we can rewrite the product like this :

5 x 3 x 10^2 x 10^2 = 15 x 10^4

Finally, we need to convert this into scientific notation :

15 x 10^4 = 1.5 x 10^5  

So the final answer is

1.5 x 10^5

Answer:

  (2x +1)/(4x^2) . . . . except x=0, -1

Step-by-step explanation:

Addition of fractions works in the usual way:

  a/b +c/d = (ad +bc)/(bd)

Division of fractions works in the usual way:

  (a/b)/(c/d) = (ad)/(bc)

__

  [tex]\dfrac{\left(\dfrac{1}{2x}+\dfrac{1}{2x+2}\right)}{\left(\dfrac{2x}{x+1}\right)}=\dfrac{1}{2}\cdot\dfrac{\left(\dfrac{1}{x}+\dfrac{1}{x+1}\right)}{\left(\dfrac{2x}{x+1}\right)}=\dfrac{1}{2}\cdot\dfrac{\left(\dfrac{2x+1}{x(x+1)}\right)}{\left(\dfrac{2x^2}{x(x+1)}\right)}\\\\=\boxed{\dfrac{2x+1}{4x^2}}[/tex]

The expression is undefined for any denominator equal to zero: x=0 or x=-1.

Answer:

Infinite solutions

Step-by-step explanation:

-(-x + 1) = x - 1

x - 1 = x - 1

Answer:

I dont see the numbers sorrry

Answer:

Step-by-step explanation:

y = mx +b

Here, m is slope and b is y-intercept

1) y = -5x - 6

Slope = -5

y-intercept = -6

2) y = 2x

Slope = 2

y-intercept = 0

Answer:

neptune = 6m+2

Step-by-step explanation:

mars has 'm' moons

pluto has one more than twice that of mars, = 2m+1

neptune is one less than thrice of pluto

= 3(2m+1) -1

= 6m+3 -1

= 6m+2

D because 2 has a x next to it so you divide by 2 on both sides

FBG= 10*

ABC= 180*

Now I will uhhhhhhhhhhhhhhhhhhhhhhhhhhhh yeah

Answer:

RQ = 10

Step-by-step explanation:

When two triangles are similar, the ratio of their corresponding sides are equal;

Thus, we have it that;

QP/RQ = BC/AB

12/RQ = 36/30

RQ = 12 * 30/36 = 10

Honest people would tell other people what they think honestly. And honestly, I don't know how to answer your question :( Honestly, I feel like I don't deserve to answer this question if I can't come up with an honest answer. I don't know, maybe I come back to this question another day when I'm older and wiser, and have an answer that will impress you with my honesty. But for now, honestly, I feel like I have failed this user.

Answer: The last graph

Quartiles, mean and medians all match up

Answer:

The goal post is 40.05 feet tall.

Step-by-step explanation:First, you need to decide whether to use sin, tan or cos.

You have the angle, the adjacent and need the opposite , so you need to find out which one has all three values in

Sin  

Cos  

Tan  

So you need to use tan.

Tan = opposite / adjacent, so rearrange the formula to make opposite the subject:

[tex]Opp = Tan * adj

So simply plug these values in:

[tex]Opp =131 * tan(17) = 40.05

So the goal post is 40.05 feet tall

Answer:

60 kilograms of the 30% solution

140 kilograms of the 40% solution

Step-by-step explanation:

Let x = the no. of kilos containing 30% salt (solution 1)

and 200 - x = the no. of kilos containging 40% salt solution 2)

.30x = amount of salt in solution 1

.40(200 - x) = amount of salt in solution 2

.37(200) = amount of salt in the final mixture

salt in solution 1 + salt in solution 2 = salt in final mix.

.30x + .40(200 - x) = .37(200)  

Let's multiply thru the equation by 100 to remove the decimal fractions

30x + 40(200 - x) = 37(200)

30x + 8000 - 40x = 7400

-10x = -600

x = 60 kilograms of the 30% solution

200 - 60 = 140 kilograms of the 40% solution
