Answer:

Deberán utilizarse 195 mililitros de la marca Nº1 (260 x 0.75 = 195), y 65 mililitros de la marca Nº2 (260 x 0.25 = 65).

Step-by-step explanation:

Si se utiliza enteramente la marca Nº1, utilizando 260 mililitros de esta el aderezo tendrá un 6% de vinagre, mientras que si se utiliza únicamente la marca Nº2, el aderezo tendrá un 10% de vinagre.

Siguiendo con esta lógica, si se utilizaran ambas marcas en igual proporción, es decir, 130 mililitros de cada una, la mezcla tendría un 8% de vinagre. Por lo tanto, es necesario utilizar un 75% de la marca Nº1 (con un 6% de vinagre), y un 25% de la marca Nº2 (con un 10% de vinagre), para lograr el deseado 7% de vinagre.

Así, deberán utilizarse 195 mililitros de la marca Nº1 (260 x 0.75 = 195), y 65 mililitros de la marca Nº2 (260 x 0.25 = 65).

Kendra has a painting canvas that is 20 inches wide by 37 inches high. She painted a red rose, which covered 50% of the canvas.
uysha [10]
The total area is:
 A = (20) * (37)
 A = 740 in ^ 2
 We can make the following rule of three:
 740in ^ 2 -----> 100%
 x --------------> 50%
 Clearing x we have:
 x = (50/100) * (740)
 x = 370 in ^ 2
 Answer:
 
the area of the canvas which was covered by the red rose was:
 
x = 370 in ^ 2

If the probability of a chance event is 0.82, it is more likely to happen than which of the following probabilities of another c
Charra [1.4K]

Answer:

0.8

Step-by-step explanation:

Things to remember:

- You can add as many 0's on the end of a decimal and it will still equal the same number, as long as the 0's are on the right side of the decimal point. For example, 0.7 = 0.7000.

- The lowest value has the lowest probability

So, let's rewrite the options with the same amount of decimal points:

1.00

0.90

0.80

0.85

Now, find the value under 0.82. In this option, the lowest value is 0.80, and it is under 0.82, so it is the answer.

Find the length of each bolded ARC round to the nearest hundredth 5 mm and 232 Help ASAP
mart [117]

9514 1404 393

Answer:

  20.25 mm

Step-by-step explanation:

Arc length is given by the relation ...

  s = rθ

where r is the radius and θ is the central angle in radians.

There are π radians in 180°, so the arc length is ...

  s = (5 mm)(232°×π/180°) = 20.25 mm

The arc length is about 20.25 mm.
