Answer:

The value of $\frac{4b}{a}$ is 240

Step-by-step explanation:

We were given the equation: a x 60 = b

To find the value of 4b/a, we are going to follow the following step;

First, divide both-side of the equation by a, thus our equation becomes:

a x 60/a = b/a

On the left-hand side of the equation, 'a' at the numerator will cancel-out 'a' at the denominator. Our equation becomes;

60 = b/a

Then, the next step is to multiply 4 to both-side of the equation, our equation becomes

4 x 60 = 4 x b/a

240 = $\frac{4b}{a}$

$\frac{4b}{a}$ =240

Therefore, the value of $\frac{4b}{a}$ is 240

Answer:

240

Step-by-step explanation:

Given

60a = b ( divide both sides by a )

60 = $\frac{b}{a}$ ( multiply both sides by 4 )

240 = $\frac{4b}{a}$

Artist 52 [7]

Answer:

52/79

Step-by-step explanation:

One costume = 156 (This is our numerator.)

All visitors = 156 + 58 + 23 = 237 (This is our denominator.)

156/237

Find the GCF to simplify (sneak peek it's 3)

156/3 = 52

237/3 = 79

I need help with #1 of this problem. It has writings on it because I just looked up the answer because I’m confused but I want t

In the figure below

1) Using the theorem of similar triangles (ΔBXY and ΔBAC),

$\frac{BX}{BA}=\frac{BY}{BC}=\frac{XY}{AC}$

Where

$\begin{gathered} BX=4 \\ BA=5 \\ BY=6 \\ BC\text{ = x} \end{gathered}$

Thus,

$\begin{gathered} \frac{4}{5}=\frac{6}{x} \\ \text{cross}-\text{multiply} \\ 4\times x=6\times5 \\ 4x=30 \\ \text{divide both sides by the coefficient of x, which is 4} \\ \text{thus,} \\ \frac{4x}{4}=\frac{30}{4} \\ x=7.5 \end{gathered}$

thus, BC = 7.5

2) BX = 9, BA = 15, BY = 15, YC = y

In the above diagram,

$\begin{gathered} BC=BY+YC \\ \Rightarrow BC=15\text{ + y} \end{gathered}$

Thus, from the theorem of similar triangles,

$\begin{gathered} \frac{BX}{BA}=\frac{BY}{BC}=\frac{XY}{AC} \\ \frac{9}{15}=\frac{15}{15+y} \end{gathered}$

solving for y, we have

$\begin{gathered} \frac{9}{15}=\frac{15}{15+y} \\ \text{cross}-\text{multiply} \\ 9(15+y)=15(15) \\ \text{open brackets} \\ 135+9y=225 \\ \text{collect like terms} \\ 9y\text{ = 225}-135 \\ 9y=90 \\ \text{divide both sides by the coefficient of y, which is 9} \\ \text{thus,} \\ \frac{9y}{9}=\frac{90}{9} \\ \Rightarrow y=10 \end{gathered}$

thus, YC = 10.

M∠1=119∘ and m∠2=61∘.<br> What is m∠3?

marin [14]

Answer:

m∠3 = 119°

Step-by-step explanation:

All the angles must equal 360° when added together. You have two known angles that are right next to each other. If you add m∠1 and m∠2, 119 + 61, it is equal to 180°. This means that m∠3 and m∠4 must be equal to 180° as well and since there are only two lines, it is safe to assume that opposing angles are the same so m∠1 = m∠3 and m∠2 = m∠4.

Answer:

B] f(n) = 6(3)n − 1; f(5) = 486

Step-by-step explanation:

First, you have to identify which type of relation the points have. From the graph you can tell that it's an exponential growth. The x values change in the same amount every time, in this case by 1.

So if the relation is exponential, if we divide the y coordinates you should get the same result every time.

18 / 6 = 3

54 / 18 = 3

162 / 54 = 3

So the y value increases 3 times. That means that the next value should be 162*3 = 486.
