A bag contains both black and red marbles. The ratio of black to red marbles is 3:4.

1 answer:

8 0

The total number of marbles in the bag is 7, since 3+4=7. There are 3:4 black marbles, so 3/7 of the bag is black marbles, which can be written as 3:7.

4/7 of the bag is red marbles, which can be written as 4:7

You would subtract.

The question is asking who has more, so to find out, you need to take away the smaller amount from the bigger amount. (1.25-1.05)

So Sandra bought more candy. Hope this helps!

What is the asymptote for the graph of this logarithmic function?<br><br> f(x) = log3(x – 1)

Pepsi [2]

Answer:

Vertical Asymptote:

$x=1$

Horizontal asymptote:

it does not exist

Step-by-step explanation:

we are given

$f(x)=log_3(x-1)$

Vertical asymptote:

we know that vertical asymptotes are values of x where f(x) becomes +inf or -inf

we know that any log becomes -inf when value inside log is zero

so, we can set value inside log to zero

and then we can solve for x

$x-1=0$

we get

$x=1$

Horizontal asymptote:

we know that

horizontal asymptote is a value of y when x is +inf or -inf

For finding horizontal asymptote , we find lim x-->inf or -inf

$\lim_{x \to \infty} f(x)= \lim_{x \to \infty}log_3(x-1)$

$\lim_{x \to \infty} f(x)=log_3(\infty-1)$

$\lim_{x \to \infty} f(x)=undefined$

so, it does not exist

The length of atrain car is 50.6 feet. This is 5.8 feet less than 6 times the width. What is the width?

hichkok12 [17]

∗ l = 50.6 ft
∗ w = ?

∗ The length is 50.6 feet. The question is saying that 50.6 is 5.8 feet less than 6 times the width.

∗ 6w - 5.8 = 50.6

∗ 6w = 56.4

∗ w = 9.4

Now lets check.

∗ If the length is 5.8 feet less than 6 times the width, and we found 9.4 as the answer, then;
6 times 9.4 - 5.8 should equal 50.6

∗ 6 • 9.4 - 5.8 = l

∗ 56.4 - 5.8 = l

∗ 50.6 = l

⋆The width is 9.4 feet⋆
