divide $70 into the ratio of 2:7: 1​

Answers

Answer:

$14:$49:$7

Step-by-step explanation:

To solve this question you first add the ratios.

So 2+7+1, which is 10. You then take this number and divide it by 70 to find 1 part. 70 divide by 10 is 7, which represents 1 part.

7 times by 2 is 14, 7 times by 7 is 49 and 7 times by 1 is 7.

Thus you get the ratio, $14:$49:$7.

And if you add 14+49+7, you get 70!

Erin buys 2 packs of potatoes costing £2 each, 3 packs of carrots for £3 per pack, and 3 turnips costing 60p each.
If she pays with a £20 note, how much change would she get in pounds, £

Answers

Answer:

  £5.20

Step-by-step explanation:

The change is the difference between the amount tendered and the amount owed. The total amount owed is the sum of the costs for each of the items purchased.

  change = £20 - 2(£2) - 3(£3) -3(£0.60) = £20 -14.80 = £5.20

Erin gets £5.20 in change.

Which expressions simplify to 0? Check all that apply.
8g – 8g
(–2g) – 2g
5g + (–5g)
One-half g + one-half g
Negative two-thirds g + two-thirds g

Answers

The expressions that simplify to zero are:

8g – 8g

5g + (–5g)

Negative two-thirds g + two-thirds g

Let us consider each of the expressions to determine the ones that simplify to zero (0)

For 8g - 8g

This is a direct subtraction of terms of the same value. Therefore, 8g - 8g = 0

For (–2g) – 2g

This can be further simplified as -2g - 2g = -4g

Therefore, (–2g) – 2g does not simplify to zero

For One-half g + one-half g

This can be written mathematically as:

[tex]\frac{1}{2}g + \frac{1}{2}g = g[/tex]

Therefore, One-half g + one-half g does not simplify to zero

Negative two-thirds g + two-thirds g

[tex]-\frac{2}{3}g+ \frac{2}{3}g = 0[/tex]

Therefore, Negative two-thirds g + two-thirds g simplifies to zero

Sorry, ignore the other question I had on here, that was a typo. How do you find the positive/negative intervals of f(x) = 3/(x + 5) ? Please show in full detail!!

Answers

Answer:

Positive interval: x is in (-5, infty)

Negative interval: x is in (-infty, -5)

Step-by-step explanation:

A fraction is positive when the numerator and denominator have the same sign. Since the numerator is positive in this case, the fraction will be positive when it's denominator is also positive. Thus, we need to solve x+5>0. Subtracting 5 on both sides gives x>-5.

Positive interval: x is in (-5, infty)

A fraction is is negative when the numerator and denominator have the different signs. Since the numerator is positive in this case, the fraction will be negative when it's denominator is negative. Thus, we need to solve x+5<0. Subtracting 5 on both sides gives x<-5.

Negative interval: x is in (-infty, -5)

A fraction doesn't have an output when it's denominator is 0. That is, in this case when x+5=0 which is when x is -5.

Answer:

Step-by-step explanation:

(5x + 35) + 45 = 180

These angles are opposites to each other so you know that together they equal 180.

Start off by adding 35 and 45. This gives you...

5x + 80 = 180

Then subtract by 80 giving you...

5x = 100

Then divide by 5. This gives you...

Plug in the given values:

[tex]\text{ oranges : total fruit} = \frac{\text{6}}{\text{15}} = 0.4[/tex]
