Answer:
Letter A.
Step-by-step explanation:
One way to know that two lines are perpendicular IF their slopes are reciprocals of one another and one slope is negative.
Slope AB is -3/4 and the slope of CD is 4/3.
- 3/4 is the reciprocal of 4/3
- One slope is negative (-3/4)
Answer:
11
Step-by-step explanation: Because if you add 2x3 it equals 6 so if u add 2x2 2 times thats ur answer when you add three.
Cd = 1/2 * 1/3
= 1/6

Answer:
There are 320 students at Milton middle school.
Step-by-step explanation:
From the information provided, you can use a rule of three to find the total amount of students at Milton middle school as you know that there are 144 girls and they represent 45% of the students:
144 → 45%
x ← 100%
x=(144*100)/45
x=320
According to this, the answer is that there are 320 students at Milton middle school.
Answer: 147 Degrees
Step-by-step explanation
The size of the final unknown interior angle in a polygon is 147 degrees.
Given that,
The other interior angles are 162°, 115°, 120°, 148° and 85°.
We assume that there is an equation (2n - 4) 90.
Here n be 7.
Based on the above information, the calculation is as follows:
= (2n - 4) 90
= ((2) (7) - 4) 90
= 10 (90)
= 900
Now the size of the unknown interior angle is
= 900-(162+125+148+105+98+115)
= 900 - 753
= 147°
Therefore we can conclude that the size of the final unknown interior angle in a polygon is 147 degrees.
