If the score is 90% and the total is 70 what is the number correct ?

1 answer:

3 0

If you mean that the total number of questions is 70, then:

1. You need to figure out what 90% is of the total, 70.
2. Do this by multiplying 70 by 90% --> 70*(.9)
3. 90% of 70 is 63. The total number correct is 63.

You can check your work by figuring out what percentage 63 is of 70. 63 divided by 70 (63/70) is .9, or 90%.

Answer:

The answer is "19".

Step-by-step explanation:

In this question, the graph file is missing which is defined in the attached file please find it.

When YZ and XW were identical,

$\angle XWY =\angle WYZ \ \ \text{(Alternate Angles)}$

$\angle XWY = 2x$

Because the angles are all 180 degrees in either a triangle:

$\to (3x - 5) + 90 + 2x = 180\\\\\to 3x - 5 + 90 + 2x = 180\\\\ \to 5 x + 85= 180 \\\\ \to 5 x = 180-85 \\\\ \to 5x = 95 \\\\ \to x= \frac{95}{5} \\\\ \to x = 19$

Answer:

Step-by-step explanation:

3^10= 3^7(x^3)

59049= 2187(x^3)

59049/2187= x^3

27=x^3

Do the square root of 3 to both sides and you end up with x=3.

Hope this helped :)

lapo4ka [179]

Brand b is 2 cents cheaper than brand a because it is 14 cents per ounce and brand a is 16 cents per ounce you do 1.68 divided by 12 and 1.28 divided by 8
