On Planet Galactica, common units of distance are alpha, beta, and gamma. 4 gammas equal 5 betas. 2 betas equal 3 alphas. How ma
Ghella [55]

Answer:

1 gamma = 15/8 alphas

Step-by-step explanation:

so we start by finding out what 1 gamma and 1 beta equals.

we know 4 gammas = 5 betas so if we divide by four on both sides we get:

1 gamma = 5/4 betas. we can apply that same procedure to 2 betas = 3 alphas and get 1 beta = 3/2 alphas

we know that 1 gamma = 5/4 betas and 1 beta = 3/2 alphas so how many alphas = 5/4 betas? using a proportion of ((3/2)/1) = ((x)/(5/4)) we can find that 5/4 betas = 15/8 alphas

therefore we know 1 gamma = 15/8 alphas or 1 and 7/8 alphas

ELEN [110]

Sajia can sell 21 books she can sell if she comes back on sunday and the required inequality is 9 + x \leq 30

<em><u>Solution:</u></em>

Given that Sajia has 30 Books in her library

She sold 9 books at the thrift store on Saturday

To find: We have to write and solve an inequality to determine number of more books she can sell if she comes back on sunday

Let "x" be the number of more books she can sell if she comes back on sunday

<em><u>We can write a inequality as:</u></em>

\text{ books already sold } + \text{ number of books remaining } \leq \text{ total number of books she has }

9 + x \leq 30

Now moving 9 from L.H.S to R.H.S we get,

x \leq 30 - 9

On solving 30 - 9 = 21,

x \leq 21

So Sajia can sell 21 books she can sell if she comes back on sunday

What is 2/3 of the distance between the points U (-1,4) and B (8,5)
BlackZzzverrR [31]

Answer:

<h2>         6.037</h2>

Step-by-step explanation:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\U (-1,4)\quad\implies\quad x_1=-1\,,\ \ y_1=4 \\\\B (8,5)\quad\implies\quad x_2=8\,,\ \ y_2=5\\\\\frac12d=\frac23\sqrt{(8+1)^2+(5-4)^2}=\frac23\sqrt{81+1}=\frac23\sqrt{82}\approx6.037
