8 0

Answer: The only correct answer is 8/18. See below

Step-by-step explanation:

All you need to do is divide the denominator of 9 into the denominator of each fraction, and multiply the numerator by the same factor like this:

4/9 = ?/36; 36/9 = 4; 4x4 =16, so we know that 4/9=16/36 NOT 20/36

4/9 = ?/18; 18/9 =2; 2x4 =8, so we know that 5/9 = 8/18 so YES.

4/9 = ?/45; 45/9=5; 5x4 = 20, so we know that 5/9 = 20/45 NOT 24/45

5/9 = ?/27; 27/9 =3; 3x5 = 15, so we know that 5/9 = 15/27 NOT 12/27

Solve for x 3x + 3 − x + (−7) > 6 A. x > (−5) B. x > 2.5 C. x > 5 D. x < 5

denpristay [2]

ANSWER

C. x>5

EXPLANATION

The given inequality is:

3x + 3 − x + (−7) > 6

Deal with the parenthesis first to obtain;

3x + 3 − x −7 > 6

Group similar terms to get:

3x − x> 6-3+7

Combine similar terms to get,

$2x \: > \: 10$

Divide both sides by 2 to obtain:

$x \: > \: 5$

The correct choice is C. x>5

In a right triangle, the side adjacent angle a is 12, the

Svetlanka [38]

Answer:

$tan(a)=\frac{opposite}{adjacent}$

Step-by-step explanation:

In a right triangle, the side adjacent angle a is 12, the

hypotenuse is 24.

Angle 'a' is 12

hypotenuse is 24

$sin(a)=\frac{opposite}{hypotenuse}$

$sin(12)=\frac{opposite}{24}$

opposite side = 24 times sin(12)=5

$cos(a)=\frac{adjacent}{hypotenuse}$

$cos(12)=\frac{adjacent}{24}$

adjacent side = 24 times cos(12)=23.5

$tan(a)=\frac{opposite}{adjacent}$

$tan(a)=\frac{5}{23.5}$

Flura [38]

Answer:

56 tablets

Step-by-step explanation:

Jonah knows that Mr. Robinson needs 14 tablets for a week's supply of an anti-inflammatory drug.

Mr. Robinson is going on vacation and needs a 4-week supply.

So multiplying 4 with the weekly supply will yield the required result.

So, number of tablets Jonia needs to fill is,

=4\times 14

=56

Therefore, Jonah needs 56 tablets in order to fill his prescription
