Answer:
no
Step-by-step explanation:
thirty percent of $28 is $8.4, so you would subtract the two leaving you with $19.6
2.5 sales tax of $19.6 is $0.49
Adding those two, the total comes to 20.09 which is just over budget
So remember range means subtract from least number from the greater number in the set.
so the smallest number in the set is 0 and the biggest number is 18.
18-0=18
Range=18

I believe it is the 4th one
Turn 4 1/2 into a fraction which is 4.5, then divide that by three. 4.5 / 3 = 1.5. So 1.5 = 1/3 of the original amount. Now all you need to do is multiply 1.5 times 2. You do this because you know that 1/3 + 1/3 = 2/3. So 1.5 + 1.5 = 2/3. 1.5 * 2 = 3. Now you have 2/3 of the original number.
Answer:
All false.
Step-by-step explanation:
The ratio is 3:4.
For every 3 girls, there are 4 boys.
If a class has 7 people, 3 are girls and 4 are boys.
Hence the fraction of boys is 4/7 and girls are 3/7.
Therefore, a and b are False.
The number of boys in the class cannot be 6. If the number of boys is 6, then the number of girls must be 4.5 to maintain the 3:4 ratio, but there cannot be half a girl. So, c is also false. d) the number of pupils in the class is 12. To maintain a 3:4 ratio, the number of pupils in the class must be in multiples of 7. Hence, d is also false.
