Answer:

x = 4 radical 3 / 3

Step-by-step explanation:

this is a 30-60-90 triangle

the side across from the angle 30 is L

the side across from the angle 60 is L√3

the side across from the angle 90 is 2L

we are given the side across from 60⁰ so we know that:

2 = L√3

we want to solve for L, so we must divide both sides by √3 (radical three)

2/√3 = L√3/√3

you would get 2/ √3 = L, because the radical three cancels out on the L side.

but you can't have a radical in the denominator, so you have to multiply 2/√3 by radical 3

2 times √3 and √3 times √3

you get 2√3/√9

radical nine can simplify

2radical3/3 or 2√3/3

we found L, but that would equal the thirty degree angle, not the 90, 90 = 2L

multiply the number infront of the radical by two and get

4√3/3

x=4 radical 3 divided by 3

Answer:

2n - 7

Step-by-step explanation:

To get the sum you would combine like terms.

So:

n + n= 2n

7 + -14 = 7 - 14 = -7

Put it together:

2n - 7

Answer:

$275

Step-by-step explanation:

If you multiply 24 by 15 you get the total which is $360. When you subtract the $85 he spent you get $275 left over that he is saving.

Answer:

p=(1,3).  R=(1,1).  Q=(3,1)

Step-by-step explanation:

This is because the verticals like is the y-ais and the horizontal like is the x-axis and in order to find coordinate points go by the rule (x,y). Therefore whatever number the point is lined up with horizontally and vertically use those numbers

Answer:

222 mL

Step-by-step explanation:

okay so lets multply them lets call the quantity of hydrocloric acid x

so 61x+ 21(277.5-x)= 53*277.5

61x+ 21*277.5-21x= 53*277.5

40x=(53-21)(277.5)

40x= (32)(277.5)

x= 222 mL

Answer: -1654

Step-by-step explanation:

a) 4.71ft

b) 3.53ft^2

Step-by-step explanation:

Perimeter is 1/2 the circumference

1/2 Circumference = 2*pi*radius

Radius = 1/2 Diameter

Radius = 3/2 = 1.5ft

Circumference = 2*pi*1.5ft = 9.42

1/2 Circumference = 4.71

4.71ft is the perimeter.

The area is 1/2 that of a full circle

A = pi*r^2

A = 3.14*1.5*1.5

A = 7.065ft^2

1/2 A = 3.53ft^2

Answer:

yes   they would be 1 25/30  and  2 6/30

Step-by-step explanation:

The equivalent fractions for 2 1/5 and 1 and 5/6 using 30 of the common denominator would be 1 25/30  and  2 6/30

A fraction has two parts: Numerator and Denominator.

It is in the form of a Numerator / Denominator. A fraction is a numerator divided by the denominator.

We need to write equivalent fractions for 2 1/5 and 1 and 5/6 using 30 of the common denominator .

Now consider the first fraction as;

2 1/5 = 11/5

Then other fraction must be multiple of the denominator of the other.

So, 1 and 5/6 = 11/6

We can see that "the denominator of one is a multiple of the denominator of other" that is 5 x 6 = 30

Thus the two fractions are; 1 25/30 and 2 6/30

Answer:

Side c has a length of √145, or approximately 12.04.

Step-by-step explanation:

Because this is a right triangle, you can use the Pythagorean theorem to solve it.  In a right triangle, the sum of the squares of the two sides is equal to the square of the hypotenuse.  Or in this example:

c² = 9² + 8²

So we can solve it:

c² = 9² + 8²

c² = 81 + 64

c² = 145

c = √145

c ≈ 12.04
