Answer 1

Answer:

Answer:

Step-by-step explanation:

5. a) ∠1 and ∠2 are remote interior angles of ∠ACD so that means that ∠ACD = ∠1 + ∠2

b) Because an exterior angle is the sum of its two remote interior angles it makes sense that an exterior angle is greater in measure than either of its remote interior angles.

6. BD = DB Reflexive property

∠3 = ∠5, ∠4 = ∠6 Alt. int. angles

ΔADB = ΔCDB ASA

7. AB = BC Def. of midpoint

∠1 = ∠2 Given

∠BAE = ∠CBD Corresponding angles

ΔBAE = ΔCBD ASA

∠D = ∠E CPCTC

Find area of the triangle 15ft 10ft 10ft

Answers

Answer:

Step-by-step explanation:

i'm going to assume that the base is 10, the formula for a triangle is base x height divided by 1/2 (or 2)

15height x 10base = 150 now divided by 2, 150/2 = 75

Answer:

P is at (2, 7), and Q is at (6, 11).

The midpoint of PQ is at (4, 9), calculated as follows:

((2 + 6)/2, (7 + 11)/2) = (8/2, 18/2) = (4, 9)

B and C? Please? I already did the table

Answers

Now you're trying hard to make something hard out of something easy.

It gives you the equation . . . C = -7.11 t + 153.9

b). Take this equation, and calculate 'C' when 't' is -20.

   Find 'C' : C = (-7.11)(-20) + 153.9

   I'm sure you can do this easily.

c). Take this equation, and calculate what 't' would have to be
   in order to have C=50 .

   Find 't': 50 = (-7.11) t + 153.9

       I'm sure you can do this easily too.

Step-by-step explanation:

3. How many people preferred WCLM?A. 88
B. 24
C. 100
D. 96

4. Which one of the following statements expresses a true proportion?
A. 3:4 = 9:12
B. 2:1 = 1:2
C. 7:9 = 8:9
D. 54:9 = 6:3

Answers

Answer:

Step-by-step explanation:

3)Total no of people surveyed = 400

Percentage of people preferred WCLM = 24%

Hence no of people who preferred WCLM = 24(400)/100

=96

3:4 =9:12 is true since when simplified both are equal

B is not right 2:1 cannot equal 1:2 as ratio is not commutative

c is not right as they are not equal when simplified

D is not right since when we divide left side by 9, we get 6:1

Answer:

Step-by-step explanation:

9 divided by 3 gives 3

12 divided by 3 gives 4

therefore 9:12 is equal to 3:4
