Answers

Answer 1

Average speed= total distance covered/total time taken

Total distance=100+30=130k.m

Total time =2+1/2 hour=2.5 hours

Average speed =130/2.5=1300/25=52 km/h

Step-by-step explanation:

Answer: The proportion is 9/w = 25/100

Step-by-step explanation:

Solve by cross multiplying

9 × 100 = 25 × w

900 = 25w . Divide both sides by 25

900/25 = 25w/25

36 = w

It is also possible to use simpler fractions if you remember that 25% is the same as 1/4

9 is 1/4 of w,

9 = w/4 So multiply both sides by 4

4(9) = 4(w/4) . The 4s "cancel" on the right

36 = w

Answers

Answer: next three terms: a_5 = -20, a_6 = -23, a_7 = -26

Step-by-step explanation:

Formula: a_n = a_1 + (n-1)d

We need to find the 5th, 6th and 7th term.

a_5 = -8 + (5-1)(-3)

a_5 = -20

a_6 = -8 + (6-1)(-3)

a_6 = -23

a_7 = -8 + (7-1)(-3)

a_7 = -26

Find the value of x and y

Answers

Answer:

x = 80, y = 122

Step-by-step explanation:

I got this equation by using vertical angles to create a complimentary angle pair (they sum to 90 degrees).

3/4x+2/5x-2=90°,

23/20x - 2=90°,

23/20x = 92°,

92/(23/20)

20/(1/4)

20(4)

= 80.

Since the angles are a linear pair on the left side(they sum to 180 degrees). Just subtract 180 from 3/4x-2 and substitute x into the expression.

180-(3/4(x)-2), 180-3/4(80)+2 = 120+2 = 122

△LMN and △NOP similar right triangles. The coordinates of all the vertices are integers.

The slope of LN¯¯¯¯¯ is equal to the slope of NP¯¯¯¯¯¯. This because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is the same for LN¯¯¯¯¯ as for NP¯¯¯¯¯¯

The relationship between the slope of LN¯¯¯¯¯ and the slope of NP¯¯¯¯¯¯ cannot be determined, because the triangles are congruent.

The slope of LN¯¯¯¯¯ is greater than the slope of NP¯¯¯¯¯¯. This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is greater for LN¯¯¯¯¯ than for NP¯¯¯¯¯¯.
