length of edges in A: length of edges in B = 3:5
The perimeter of A is 345 mm
Work out the perimeter of B in mm.

Answers

Answer 1

Answer:

575 mm

Step-by-step explanation:

The ratio of perimeters is the same as the ratio of sides.

let x be the perimeter of B then by proportion

[tex]\frac{3}{345}[/tex] = [tex]\frac{5}{x}[/tex] ( cross- multiply )

3x = 1725 ( divide both sides by 3 )

x = 575

Then the perimeter of B is 575 mm

How come this person didn’t divide EVERYTHING on the left by 2? I thought you had to...

Answers

The short answer is that algebra doesn't work that way. You wouldn't divide *everything* by 2, but every term that contains a factor of 2.

In the expression

2 (6x - 1) + 2 (2x + 5)

both terms have a factor of 2 (the 2 out in front of them). They're the ones that get canceled when dividing by 2:

(2 (6x - 1) + 2 (2x + 5)) / 2 = 2/2 (6x - 1) + 2/2 (2x - 5)

… = 1 (6x - 1) + 1 (2x - 5)

… = (6x - 1) + (2x - 5)

and so on.

Looking ahead, it turns out that the equation is solved by x = 7. This makes 6x - 1 = 41 and 2x + 5 = 19. So the equation is saying that, if you make these replacements,

2×41 + 2×19 = 120

If you divide *everything* on the left by 2, you end up with fractions:

(2/2)×(41/2) + (2/2)×(19/2) = 41/2 + 19/2

but 41 + 19 = 60, so the end result would be 30, but that's not the same as 120/2 = 60.

The lifespans of gorillas in a particular zoo are normally distributed. The average gorilla lives 20.8 years; the
standard deviation is 3.1 years.
Use the empirical rule (68 – 95 - 99.7%) to estimate the probability of a gorilla living between 11.5 and 27 years.

Answers

If the mean is 20.8, one standard deviation each way is adding and subtracting 3.1, so 17.7 and 23.9 (68% of values)

Two standard deviations adding and subtracting 3.1*2 = 6.2, or 14.6 and 27.

Three standard deviations is 11.5 and 30.1

So we have
11.5 - 14.6 - 17.7 - 20.8 - 23.9 - 27 - 30.1

Going left to 11.5 is 3 standard deviations out, so 99.7/2 = 49.85%

Going right to 27 is 2 standard deviations out, so 95/2 = 47.5%

Add those two % to get 97.32%

This is hard to do without a picture so I hope that helps!

The ratio table shows the costs for different lengths of silver chain. Find the unit rate in dollars per inch

Length (inches) 16 18 20 22

Cost (dollars) $36.00 $40.50 $45.00 $49.50

The unit rate is $__ per inch.​

Answers

Answer:

2.25

Step-by-step explanation:

yes

The unit rate of the silver chain is $0.44 per inch.

What is the unit rate?

Unit rate is the ratio of two different units, with denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc. Arithmetic is probably the most basic and ancient branch of mathematics and is quite commonly used in our day-to-day life.

Given here: 16 inches of silver chain costs $36 and 18 inches cost $40.50

Thus we have the unit rate( dollar/inch) =36/16=40.50/18=4/9

Therefore the unit rate is given by 4/9 or 0.444 dollar per inch.

Hence, The unit rate of the silver chain is $0.44 per inch.

Answer:

Step-by-step explanation:

You take the 8 and multiply each term by in the parentheses by 8, so

8(3y - 4) becomes 8 * 3y - 8 * 4 = 24y - 32

Answer:

well, you can multiply them, to simplify the equation, but to expand, try adding or multiplying 2 multiples of 8, in the middle the 4 can change by adding 2+2 or 3+1. For 3y, you can do 3*y.
