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.
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
I just need to make sure my answer is correct :)
Answer:
Its positive
Step-by-step explanation:

x+y=12
x-y=-4
-----------
2x=8
or, x = 4 put the value of x in first equation
4+y= 12
or, y=12-4
or, y= 8 hence the two number is 4 and 8

A ceramic vase that cost an antique store $7 was marked $63. What is the percentage markup on the price of the ceramic vase?
A-56%
B-900%
C-800%
D-44%
9514 1404 393
Answer:
C) 800%
Step-by-step explanation:
The markup amount is the difference between the selling price and the cost:
markup = selling price - cost
markup = $63 -7 = $56
The percentage markup relative to the cost is ...
markup/cost × 100%
= ($56)/($7) × 100%
= 8×100% = 800%

Answer:
root3/ root2
Step-by-step explanation:
since this is a special right triangle (45, 45, 90) we can use right triangle rules. Basically, C in my photo is equal to the hypotenuse while A and B are equal to the sides. You can substitute your hypotenuse into the formula I gave you to find x.
B = C / root2
x = root3 / root2

Step-by-step explanation:
From the question, we are informed that Brock divided all of his games into 3 shelves, and there were at least 12 games on each shelf.
The inequality that matches this scenario will be:
x ≥ 12.
Since there were at least 12 games, we would use the greater than or equal to sign.

Y varies inversely with x, if y = -12 when x = 8 what is x when y = -9
Answer:
either 5 or 11
Step-by-step explanation:
(8, -12)
(5, -9) or (11, -9)
If y varies consistently with x then it would copy what happens, in a manner of speaking.
In this case, y increases by three, x would either add 3 or subtract 3

What is 3/4 x 6 , simplified .
Answer:
9/2
Step-by-step explanation:
3/4 x 6 can be thought of as multiplying 3/4 x 6/1
When multiplying fractions, multiply the numerator (top number) with the numerator, and the denominator with the denominator.
3/4 x 6/1 = (3x6)/(4x1)
3/4 x 6/1 = (18)/(4)
3/4 x 6/1 = 9/2
