1. Find m2K.

Mathematics
1 answer:
Kruka [31]4 years ago
5 0

Answer:

m∠k = 60°

Step-by-step explanation:

  • an exterior angle of a triangle is equal to the sum of the opposite interior angles

4x + 2 + 6x - 12 = 130

to find x:

4x + 2 + 6x - 12 = 130

4x + 6x = 130 - 2 + 12

10x = 120

x = 120/10

x = 12

apply the value of x to find the measure of angle K:

k = 6*12 - 12 = 60

Write a linear equation that goes through the points (0,4) and (4,10). A. y =3⁄2x + 4 B. y =3⁄2x – 4 C. y =2⁄3x – 4 D. y =2⁄3x +
Elena L [17]

Answer:

A

Step-by-step explanation:

To write the equation, find the slope of the line using the two points. Find the difference in y values over the difference in x values.

\frac{y_2-y_1}{x_2-x_1} = \frac{10-4}{4-0}=\frac{6}{4}=\frac{3}{2}

Write the equation using the slope m=3/2 and the point slope form.

y-y_1=m(x-x_1)\\y-10=\frac{3}{2}(x-4)

This is the equation of the line. You can convert it to slope intercept form:

y-10=\frac{3}{2}(x-4)\\y-10 = \frac{3}{2}x - 6\\y=\frac{3}{2}x +4

Mr Lee has a family of 6 people and Mrs Scarlett has a family of 4. They were given 15 kg of chocolate
faust18 [17]

Answer:

Mr. Lee takes home 9 kg of chocolate.

Mrs. Scarlet takes home 6kg of chocolate.

Step-by-step explanation:

Mr. Lee has a family of 6 people, and Mrs. Scarlett has a family of 4 people.

Together, the total number of people is 6 + 4 = 10

If we divide evenly the chocolate between all 10, then each one gets the same amount.

Then we need to do the quotient:

15kg/10 = 1.5kg

This means that each person gets 1.5kg of chocolate.

And Mr. Lee has 6 on his family, then the amount of chocolate that Mr. Lee takes home is 6 times 1.5 kg

6*1.5kg = 9kg

Mr. Lee takes home 9 kg of chocolate.

Mrs. Scarlett has a family of 4 people, then she takes home 4 times 1.5kg of chocolate, this is:

4*1.5kg = 6kg

Mrs. Scarlet takes home 6kg of chocolate.
