pentagon [3]

Question 1:

We are going to add.

1/5 + 1/2

2/10 + 5/10

7/10

Note that we are going DOWN so the number will be negative.

Therefore, the answer is A.) -7/10

Question 2:

We are going to subtract.

4 1/2 - 1 2/3

9/2 - 5/3

27/6 - 10/6

17/6 or 2 5/6

Note that we are still BELOW sea level so the number will be negative.

Therefore, the answer is C.) -2 5/6

Question 3:

We are going to subtract.

2 2/3 - 1 1/5

8/3 - 6/5

40/15 - 18/15

22/15 or 1 7/15

Therefore, the answer is B.) 1 7/15

The measure of L in triangle LMN is 36°. The measure of M is 75°. What is the measure of N? PLEASE HELP
Alekssandra [29.7K]

Answer:

C.    m∠N = 69°

Step-by-step explanation:

The sum of the measures of the angles of a triangle is 180.

m∠L + m∠M + m∠N = 180

36 + 75 + m∠N = 180

111 + m∠N = 180

m∠N = 69°

Find the coordinates of the midpoint of the segment whose endpoints are H(10, 1) and K(4, 7).
Oliga [24]

The formula of a midpoint of a segment AB:

A(x_A;\ y_A);\ B(x_B;\ y_B)\\\\M_{AB}\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)

We have:

H(10; 1); K(4; 7)

substitute:

M_{HK}\left(\dfrac{10+4}{2};\ \dfrac{1+7}{2}\right)\to M_{HK}\left(\dfrac{14}{2};\ \dfrac{8}{2}\right)\to M_{HK}(7;\ 4)

Answer: (7, 4)

AB:BD = 3:4 <br><br> AC:CD = 3:2 <br><br> Work out AB:BC:CD
Papessa [141]

Answer:

15:6:14

Step-by-step explanation:

AB:BD is split into a total of 3+4=7 parts.

AC:CD is split into a total of 3+2=5 parts.

So, if the two ratios are put on a number line together with the points A, B, C, and D, the number line would be split into a total of 35 parts (the LCM of 7 and 5).

AB would be (3/7)*35=15.

CD would be (2/5)*35=14

BC would be 35-(15+14)=6

So, the ratio is 15:6:14.
