There are 250 students in the 6th grade 45% of the eat lunch in 4th period how many students eat lunch in 4th period?

horrorfan [7]

Answer: 112.5

Step-by-step explanation:

The question really is asking whats 45% of 250

1. Calculate 10% of the total

2. Calculate 5% of the total

3. Solve for 40% of the total

4. Add 5% of the total

1. 10% of 250

250 = 100%

*divide both sides by 10*

25 = 10%

2. 5% of 250

25 = 10%

*divide both sides by 2*

12.5 = 5%

3. 40% of 250

10% + 10% + 10% + 10% = 40%

25 + 25 + 25 + 25 = 40%

50 + 50 = 40%

100 = 40%

4. 45% of 250

100 = 40%

12.5 = 5%

100 + 12.5 = 40% + 5%

<em>112.5 = 45%</em>

3 lines are shown. A line with points C, A, F intersects a line with points E, A, B at point A. A line extends from point A to p

Verizon [17]

Answer:

m < EAD = 29 degrees

m < CAB = 119 degrees

Given :

The question states that m < CAE = m<FAB = 61 degrees and m<DAF = 90 degrees

Solution:

1. Since line CAF and EAB intersect each other, m<CAF = m< EAF - (opposite vertical angles are equivalent)

2. m<BAC + m<EAC = 180 degrees (sum of linear pair)

3. m<CAB = 180 degrees - m<EAC

4. Equation 1: m<CAB = m<EAF = 119 degrees

5. m<EAF = m<EAD + m< DAF

6. m<EAD = m<EAF - m<DAF

7. m<EAD = 119 degrees-90 degrees = 29 degrees

Hope this helps!!! :)

An objects speed can be modeled with the equation s=24(1.06)^t where s represents its speed in miles per hour and t represents t

4vir4ik [10]

$s = 24(1.06)^{t} 
$

24 is the numerical coefficient

1.06 is the base of the power with exponent t
