A) Solve 3(x - 5) = 18

You and your brother are reading the same novel. You want to get ahead of him in the book, so you decide to read 303030 minutes

ddd [48]

You will read for 45 minutes if your brother reads for 15 minutes.

Explanation

You decide to read 30 minutes longer than your brother reads.

If your brother reads $x$ number of minutes, then 30 minutes longer than $x$ minutes means $(x+30)$ minutes.

As the number of minutes you read is $y$ , so the equation will be: $y= x+30$

When your brother reads for 15 minutes, then we will just plug $x=15$ into the above equation. So.....

$y=15+30= 45$

So, you will read for 45 minutes if your brother reads for 15 minutes.

A glitter glue recipe takes a mixture of 1 5 cup of glitter to 2 5 cup of glue. For A, how many cups of glitter are used for 1 c

tatiyna

0.6 cup of gliter is used for 1 cup of glue and 1.6 cup of gliter glue is made with 1 cup of glue.

Part A

Given that,

15 cup of gliter is for 25 cup of glue ,

Therefore, "X" cup of gliter is for 1 cup of glue

X = (1*15)/25

X= 0.6 cup of gliter

Part B,

Given that,

From part A 0.6 cup of gliter is for 1 cup of glue

Thus, 1 cup of glue and 0.6 cup of gliter when mixed will form "Y" cup of gliter glue

Now, Y= 0.6 cup of gliter + 1 cup of glue

Y= 1.6 cup of gliter glue

which approximates to 2 cup of gliter glue.

Select all of the following statements that are true.

-Dominant- [34]

Answer:

3. Correlation coefficients can be represented by the variable r

Step-by-step explanation:

Correlation coefficients show if there is a strong or weak positive or negative relationship, or if there is no relationship between the variables.

Correlation coefficients are negative when the relationship is inversely proportional and positive when the relationship is proportional.

Correlation coefficients can be any value less than or equal to 1 or greater than or equal to -1.

Assume that y varies inversely with x. If y=1/3 when x=1/2, find y when x=1/4.

LenKa [72]

Answer:

y = $\frac{2}{3}$

Step-by-step explanation:

Given that y varies inversely with x then the equation relating them is

y = $\frac{k}{x}$ ← k is the constant of variation

To find k use the condition y = $\frac{1}{3}$ when x = $\frac{1}{2}$ , thus

$\frac{1}{3}$ = $\frac{k}{\frac{1}{2} }$ = 2k ( divide both sides by 2 )

k = $\frac{1}{6}$

y = $\frac{1}{6x}$ ← equation of variation

When x = $\frac{1}{4}$ , then

y = $\frac{1}{6(\frac{1}{4}) }$ = $\frac{1}{\frac{3}{2} }$ = $\frac{2}{3}$
