Answer:
250 students
Step-by-step explanation:
Let the number of sixth grade students be represented by = x
We were told that:
At a school, 40% of the sixth-grade students said that hip-hop is their favorite kind of music. 100 sixth-grade students prefer hip hop music.
Hence:
40% of x = 100
40/100 × x = 100
40x/100 = 100
Cross Multiply
40x = 100 × 100
x = 10000/40
x = 250
The number is sixth-grade students is 250 students
Answer:
12 yards
Step-by-step explanation:
h = (3×198)/(½×11×9)
= 594/(49.5)
= 12 yds
Answer:
Step-by-step explanation:
1. Since, it is given that ABCD is a parallelogram, therefore opposite angles of parallelogram are equal, hence
∠B=∠D
⇒7x-31=5x+13
⇒2x=44
⇒x=22
Hence, option B is correct.
2. Since, we get x=22, therefore
∠B=7x-31=7(22)-31=154-31=123°
∠B=123°
and ∠D=5x+13=5(22)+13=123°
∠D=123°
Also, ∠A+∠D=180°(corresponding angles)
⇒∠A=180-123
⇒∠A=57°
Now, ∠A=∠C=57°(opposite angles of parallelogram)
thus, Two of the angles measure 57°, and the other two measure 123°.
Therefore, option A is correct.
