The ratio of red, blue, and white stars on the bedroom ceiling is 2:3:5. How many blue stars are there if there are 30 stars on the ceiling?

Answers

R : B : W
2 : 3 : 5

1. Find the total of the ratio (2 + 3 + 5 = 10)
2. Work out what you do to 10 to get 30 (multiply by 3)
3. Multiply the blue ratio by three (3 x 3 = 9)

Check:

Do the same to the other colours:
2 x 3 = 6 and 5 x 3 = 15

Add together 6, 9 and 15 - the answer is 30 which is correct.

Which could be used to evaluate the expression -6(4 2/3)?

Answers

Answer:

The answer is A

-6[4 2/3]

= -6[4+2/3] because 4 2/3 is 4 and 2/3rds

so a(b+c) = a(b) + a(c)

so -6(4) + -6(2/3)

How to do:-

Here, we are given with an equation in which we are given with some constants and two same variables x. We are said that the LHS and RHS are equal to each other. We are asked to find the value of the variable x. To find the value of x, we use an other concept which helps us to find the value of x and also to verify our answer. This concept is called as the transposition method. While using this method, the sign of the appropriate number or variable changes. We use this method to shift the numbers and variables on two separate sides. We can also verify our answer at the end of our answer by verification method. So, let's solve!!

[tex]\:[/tex]

Solution :-

[tex]{\sf \leadsto 4x - 9 = 2x + 7}[/tex]

Shift the variable value to LHS and the constant value to RHS, changing it's sign.

[tex]{\sf \leadsto 4x - 2x = 7 + 9}[/tex]

Subtract the values on LHS and add the values on RHS.

[tex]{\sf \leadsto 2x = 16}[/tex]

Shift the number 2 from LHS to RHS.

[tex]{\sf \leadsto x = \dfrac{16}{2}}[/tex]

Simplify the fraction to find the value of x.

[tex]{\sf \leadsto x = 8}[/tex]

[tex]\:[/tex]

[tex]{\red{\underline{\boxed{\bf So, \: the \: value \: of \: x \: is \: 8.}}}}[/tex]

━━━━━━━━━━━━━━━━━━━━━━━

Verification :-

[tex]{\sf \leadsto 4x - 9 = 2x + 7}[/tex]

Substitute the value of x.

[tex]{\sf \leadsto 4(8) - 9 = 2(8) + 7}[/tex]

Multiply the numbers in the bracket.

[tex]{\sf \leadsto 32 - 9 = 16 + 7}[/tex]

Subtract the values on LHS and add the values on RHS.

[tex]{\sf \leadsto 23 = 23}[/tex]

So,

[tex]{\sf \leadsto LHS = RHS}[/tex]

In evaluating the limits of rational functions, the numerator and the denominator was found out to be both equal to zero, what does it mean?

Answers

Answer:

If only numerator found as zero the answer would be zero. If only denominator found as zero the answer is undefined. In your situation both are zero. But, when denominator becomes zero the answer always be undefined. Therefore, your answer is undefined when both numerator and denominator are zeros.

The Y-intercept in this problem represents if no DVDs were bought (and only the S&H was present)

No, our friend is not correct. I know this because judging from our graph, the real cost for 12 DVDs would be $114.

It would cost $456 for 50 DVDs (that’s a lot of cash!)

(Graph seen in picture below)

Equation: y = 10x + 0

Compared to the first website, the price per DVD is seems to be higher. I know this because of two points I compared on the graphs for each website. On the first website 30 DVDs cost $276 (30, 276) while on the second website 30 DVDs cost $300. This is same for 50 DVDs. On the first website they cost $456 while on the second it cost 500.

Find two numbers whose product is -6 and whose sum is 1.

Answers

Answer:

-2, 3

Step-by-step explanation:

yeah that's it I don't have any explanation or formula

let the numbers be x and y

xy = -6

x + y = 1

from x + y = 1

y = 1 - x

x(1 - x) = -6

x - x² + 6 = 0

-x² + x + 6 = 0

on solving,

x = -2 or x = 3

y = 1 - (-2) = 3

y = 1 - 3 = -2

x1 = -2, y1 = 3.

x2 = 3, y2 = -2.
