Answer:
multiply the ratio of quantities by 100%
Step-by-step explanation:
You usually explain a process by describing how it is done. The ratio of two quantities is expressed as a percentage by multiplying that ratio by 100%.
<u>Example</u>
A as a percentage of B is (A/B)×100%.
_____
You will often see a description of finding a percentage as involving multiplication by 100. What multiplication by 100 does is give you a quantity 100 times as large. Generally, that will not be the number you are looking for.
For example, <em>one out of four</em> as a percentage is not (1/4)·100 = 25. 25 is two tens plus 5, a number way larger than 1/4. Rather, it is (1/4)·100% = 25%.
"Percent" and "hundredths" are interchangeable. The percent symbol (%) is a shorthand way to write /100, which is what it means. Consider the above example:
25% = 25/100 = 1/4 . . . . these are all the same value, written differently
In decimal, ...
25% = 25/100 = 0.25 . . . . these are all the same value, written differently
Answer:
2√424 + 62 ≈ 103.1825205639 ≈ <u>103.2 units</u>
Explanation:
Given the two baselengths, and the perpendicular height of the trapezoid, you can actually find the perimeter through the pythangorean theorem because the perpendicular height or height that forms a right or 90 degree angle makes a right triangle(2 be exact because this is an isoceles trapezoid which has two adjacent right triangles).
This is true of the trapezoid is icosceles.
Answer:
504 kilos de manzanas fueron llevados a la escuela.
Step-by-step explanation:
Sean 
, 
la cantidad de cajas de manzanas y peras, respectivamente. De acuerdo con el enunciado, tenemos el siguiente sistema de ecuaciones:
Total de cajas
(1)
Masa de cada caja de peras
(2)
(3)
Masa de caja de manzanas
(4)
De (2) en (3), tenemos que la masa de cada caja de peras es:
Por (4), encontramos que la masa de cada caja de manzanas es:
Finalmente, de (1) tenemos la cantidad de cajas de manzana:
La cantidad de kilos de manzanas llevada a la escuela se obtiene al multiplicar la cantidad de cajas de manzana por la masa de cada caja:
504 kilos de manzanas fueron llevados a la escuela.
Answer:
$173.90
Step-by-step explanation:
The most obvious way to answer this question is to multiply $9.40 by 18.5
This would result in 173.90.
But I realize nobody like to deal with decimals in a multiplication problem, so here's the way I would do it (<em>especially if you don't have a calculator!</em>)
The strategy is to break it down!
Multiply $9.40 x 18 hours to start, since this is easier.
So, that's $169.20 for 18 hours of work.
We aren't finished, because Abdel worked for 18.5 hours.
So, what half of $9.40?
= 4.7
-or-
$4.70
So, knowing that Abdel makes $4.70 in half an hour, lets just add that onto the $169.20 we got earlier.
169.2 + 4.7 = 173.9
-or-
$173.90 for 18.5 hours of work!
Exterior angle c = the sun of the two opposite interior angles a and b.
10x -23 = 5x -17 + 7x -26
Combine the right side:
10x -23 = 12x -43
Add 43 to both sides:
10x +20 = 12x
Subtract 10x from both sides:
20 = 2x
Divide both sides by 2
X = 10
Now you have x replace it in the equation for A:
A = 5x -27 = 5(10) -27 = 50-27 = 23
Angle A = 23 degrees.
