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

Answer:
a. 90 degrees (given)
b. 270 degrees (360-90)
c. 16π (Circumference= diameter * π, diameter= 2r= 2(8)=16, so c= 16*π)
d. 4π (That section is a semicircle, so length should be 1/4 the circumference)
e. 12π (This section is 3/4 the circumference)
f. 64π (Area= πr^2, and r^2= 8^2= 64, so 64π)
g. 16π (That section is 1/4 the area)

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

Find the slope of the line passing through the points (-9,4) (8,4)
Answer:
slope = 0
Step-by-step explanation:
1) Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], to solve for the slope. Use the x and y values of the given points, substitute them into the formula, and solve like so:
[tex]m = \frac{(4)-(4)}{(8)-(-9)} \\m = \frac{4-4}{8+9} \\m = \frac{0}{17} \\m = 0[/tex]
Thus, the slope is 0.

Can someone please help me understand how to expand 8(3y-4). Please give a detailed explanation.
Answer:
24y - 32
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.

Answer:
A
Step-by-step explanation:
use both points to find the slope using the equation
y2-y1/x2-x1, so , -2-4/2-0 = -6/2 = -3. slope or m = -3
then the y int can be any y point, so either -2 or 4. in this case they used 4.
