Use addition to solve the system of linear equations. Include all of your work in your final answer.

Answer:

Yes

Step-by-step explanation:

When adding fractions which have unequal denominator values, the first step is to find a way in which all the denominators conform to a common denominator value which is achieved by obtaining the lowest common factor of the denominator values.

The L. C. M of 3, 9 and 15 is : 45

1/3 + 7/9 + 4/15

Npq we have a common denominator value :

(15 + 35 + 12) / 45

= 62 / 45

Answer:

14.5

Step-by-step explanation:

The pythagoreom theorum shows a^2 + b^2 = c^2. Therefore, c^2 - a^2 = b^2

256 - 44.89 = 211.11

The square root of 211.11 rounded to the first decimal place is 14.5

The length of BC is 14.5 cm

The Pythagoras theorem states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Given

AB = 6.7 cm

AC = 16 cm

According to the Pythagoras theorem of triangles

[tex]a^{2} +b^{2} =c^{2}[/tex]

[tex]AB^{2} +BC^{2} =AC^{2}[/tex]

[tex]BC^{2} =AC^{2} -AB^{2}[/tex]

[tex]BC ^{2} =16^{2}-(6.7)^{2}[/tex]

[tex]BC = \sqrt{16^{2} -(6.7)^{2} }[/tex]

BC = 14.5 cm

Hence, the length of BC is 14.5 cm

Answer:

If a^2 + b^2 =c^2, then the triangle is a right triangle.

Step-by-step explanation:

Given

Shape: Triangle

Sides: a, b, c

Longest: c

Required

Select the true statements (See comment section for options)

From the options, we can see that we need to prove if the triangle is right-angled or not.

Since side c is the longest side, it means that side c is the hypotenuse.

Applying Pythagoras theorem

We have that:

[tex]a^2 + b^2 = c^2[/tex]

If the above mathematical statement is true, then the triangle is right-angled

Answer:

If a^2 + b^2 =c^2, then the triangle is a right triangle.

1. 17.59

2. 81.68

3. 8.99225

4. 12.00028

Step-by-step explanation:

for the first two you have to multiply the radii by 2 to find the diameter, then multiply your diameter by pi (3.14) to find the circumference

for the second two you have to work backwards so you have to divide the circumference by pi (3.14) which will give you the diameter, then you have to divide the diameter by 2 to get the radius.

Answer:

B. The degree measure of the diameter and the degree measure of the semicircle are the same.

Step-by-step explanation:

Semicircle and diameter in a circle are related because the degree measure of the diameter and the degree measure of the semicircle are the same.

The diameter of a circle is the the line that passes through the centre of a circle and meets the circumference at opposite end. The diameter divides a circle into semi circle. Therefore, the degree measure is 180 degrees.

Semi Circle is half of a circle. It is from the diameter of a circle you cut out a semi circle. The degree measure of a circle is 360 degree while the degree measure of half of a circle(semi circle) is 180 degrees.

Therefore, the degree measure of the diameter and the degree measure of the semicircle are the same.

Answer:

x = 6

Step-by-step explanation:

Sum of all the angles of a kite = 360

∠W + ∠Y + ∠V = 360

18x - 2 + 12x + 2  + 90 + 90 = 360          {Combine like terms}

18x + 12x  -2 + 2 + 90 +90  = 360

                  30x  + 180        = 360

                                30x    = 360 - 180

                                30x = 180

                                    x = 180/30

x = 6
