Answer 1
Answer:

Answer:

Option C- 60%

Step-by-step explanation:

Given :

Gender :  Grade 9       Grade 10        Grade 11       Grade 12

Male:            53                 19                   27                 37

Female:         31                 42                  50                 61

To find : Percentage of females are in grades 11 and 12

Solution: Total number of females= 31+42+50+61= 184

Number of females in grades 11 and 12 = 50+61 = 111

Percentage of females are in grade 11 and 12 = (No. of females in 11 and 12/total no. of females) × 100

\Rightarrow (111)/(184)*100=(11100)/(184)=60.32

Percentage is approx. = 60%

Therefore, option C is correct

Answer 2
Answer: There are 31+42+50+61=184 total females, and 50+61=111 females in grades 11 and 12, so the percentage is 111/184*100=60.33 percent, which can be rounded to 60%.

What is arithmetic?

The branch of mathematics dealing with the properties and manipulation of numbers.

Given that :

22 hours / week

1 hour = $15.80

So,  if he works 22 hours per week he take total home pay is

=22 * 15.80

= $347.60

This means that he makes $347.60 per week.

If it take him to save at least $4,800 then

=4,800 divided by 347.60 is 13.8089758343

In decimal can't have 0.8 of a week, so round up. This means it will take him about 14 weeks.

So, it take him to save at least $4,800 is14 weeks.

Oil has a volume of 9000cm cubed and a density of 0.8g/ cm cubed. what is the mass of the oil?

Answers

Density = 0.8 g/cm³

Volume = 9000 cm³

D = m / V

0.8 = m / 9000

m = 0.8 x 9000

m = 7200 g

System of equations,

3x - 6y =2

5x + 4y = 1

Answers

3x-6y=2 (label equation 1)
5x+4y=1 (label equation 2)
-6y=-3x+2 (rearranged equation 1)
y=1/2x-1/3 (label equation 3)
 substitute equation 3 into equation 2 
5x+4(1/2x-1/3)=1
5x+2x-4/3=1
15x+6x-4=3 (multiplied everything by 3)

21x-4=3
     +4  +4
21x=7
x= 7/21
x=1/3
sub x=7/21 into equation 3
y= 1/2(1/3) -1/3
y= -1/6


Therefore x=1/3 and y= -1/6
