Answer:
30 mph
Step-by-step explanation:
First we need to find the distance travelled in the first 1h30m.
We can do that multiplying the speed by the time travelled, so we have:
Distance1 = 50 * 1.5 = 75 miles
If the total distance is 120 miles, Michael still needs to travel 120 - 75 = 45 miles.
And if the total time travelled is 3 hours (10 AM - 7 AM), the second part of the travel has a duration of 3h - 1.5h = 1.5h
So if the distance is 45 miles and the time is 1.5 hours, we can find the speed of the second part:
45 = speed * 1.5
speed = 45/1.5 = 30 mph
Answer:
X=80
Step-by-step explanation:
65 + 35=100
180-100=80

Answer:
43°
Step-by-step explanation:
<h2>
<u>Equation:</u></h2>
<u />
m∠ABD = m∠1 + m∠2
Substitute:
68° = m∠1 + (m∠1 + 18°)
<h2>
<u>Solve:</u></h2>
68° = m∠1 + (m∠1 + 18°)
68° = 2(m∠1) + 18°
50° = 2(m∠1)
25 = m∠1
<h2>
<u>Solution:</u></h2>
<u />
Know that we know that m∠1 is, we can add 18* to find m∠2
25° + 18° = 43°

Answer:
1. A = 40 units²
2. A = 72 units²
3. B) 45
Step-by-step explanation:
1. This shape comprises 4 congruent triangles with base of 5 units and height of 5 units.
Area of a triangle = 1/2 x base x height
Therefore, area of polygon = 4(1/2 x 5 x 4)
= 40 units²
2. This shape comprises two pairs of congruent triangles.
Area of a triangle = 1/2 x base x height
Therefore, area of polygon = 2(1/2 x 2 x 6) + 2(1/2 x 10 x 6)
= 72 units²
3. Count the number of shaded squares:
9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 45 units²
Answer:
Step-by-step explanation:
Starting from the y-intercept of ![[0, 1]](https://tex.z-dn.net/?f=%5B0%2C%201%5D)
, we do 
by either moving two blocks <em>south</em><em> </em>over three blocks <em>west</em><em> </em>or two blocks <em>north</em><em> </em>over three blocks <em>east</em><em> </em>[<em>west</em> and <em>south</em> are negatives].
