Answer:
a= 18 girls in the class, b= 20 boys and 15 girls, 12 oranges better price.
Step-by-step explanation:
for question a, there are 18 girls in the class, this is how i worked it out:
the ratio of boys to girls is 4:3.
there are 24 boys.
24 is 6 times more than 4.
if boys are 6 times more than the original ratio, we also have to times the amount of girls by 6.
6x3= 18.
for question b i got 20 boys and 15 girls, this is how i did it.
there are 35 students in total.
4:3= boys to girls.
4+3=7
7 goes into 35 five times.
ratio of boys to girls is 4:3 so 5x4 for boys = 20 and 3x5 for girls = 15.
answer= 20 boys and 15 girls.
12 oranges is a better deal, this is how i worked it out.
it is 60 for 12 oranges.
it is 48 for 8 oranges.
12x5= 60 , 8x6=48.
you only have to times 12 by 5 to get it to the price but you have to times 8 by 6 to get it to the price, proving that 12 oranges for 60 is a better deal.
Answer:
188
Step-by-step explanation:
10*5*4 - 6*2
Answer:
1. 450
2. 8(12)+3(2.50)
3. 10
4. 32
Step-by-step explanation:
1. 700-250=450
2. 8 people going to the theater. If tickets cost $12 each, you multiply 8 by 12 to get the ticket cost. If 3 people ordered drinks and drinks cost $2.50, you multiply 3 by 2.50 to get the drink cost. Since this is asking for the total cost you add your first 2 answers to get the final cost.
3. 12/3=4, which means one pound costs $4. To find the amount bought with $40, divide 40 by 4, which equals 10 pounds.
4. To find percents, you turn your percentage into a decimal by dividing by 100. (400/100=4), then you multiply that by the number you are trying to find a percentage of(8x4=32). This gives you the answer 32.
3 x 6 = 18
So your answer is 18

Answer: D) Ray NM</h3>
Ray NP starts at point N as the fixed endpoint and goes off forever in the direction of point P.
The opposite would be to turn 180 degrees and go the other way. So we start at N and instead go off forever toward point M. In either case, the starting point is still the same (point N).
When naming rays, the order is important. Ray NM is different from ray MN. This is because the first letter is the fixed end point (that doesn't go off forever in one direction).
