Answer :
Let's go through each of the questions one by one:
To find 38% of 550, you can use the formula for percentage calculation:
[tex]\text{Percentage} = \frac{\text{Percentage Value}}{100} \times \text{Whole Value}[/tex]
So, 38% of 550 is:
[tex]0.38 \times 550 = 209[/tex]
Therefore, the answer is D. 209.Adding 4 and 2 together:
[tex]4 + 2 = 6[/tex]
However, the choices do not seem relevant, so I will not select an option from the provided list.To find the total number of bricks required:
[tex]72{,}565 + 33{,}290 = 105{,}855[/tex]
Therefore, the answer is A. 105 855.Factors of 24 are numbers that divide 24 without leaving a remainder. Thus:
- 2 is a factor of 24 (since [tex]2 \times 12 = 24[/tex])
- 3 is a factor of 24 (since [tex]3 \times 8 = 24[/tex])
- 5 is not a factor of 24
- 6 is a factor of 24 (since [tex]6 \times 4 = 24[/tex])
Thus, C. 5 is not a factor of 24.
- To arrange [tex]\frac{1}{2}[/tex] and [tex]\frac{1}{3}[/tex] in ascending order, convert them to a common denominator, if needed:
- [tex]\frac{1}{2} = 0.5[/tex]
- [tex]\frac{1}{3} \approx 0.333[/tex]
Therefore, in ascending order is B. [tex]\frac{1}{3}, \frac{1}{2}[/tex].
One right angle is 90°. Therefore, three right angles are:
[tex]3 \times 90° = 270°[/tex]
The answer is B. 270°.To calculate the mass of the engine, subtract the weight of the empty box from the gross mass:
[tex]165{,}245 - 45.5 = 165{,}199.5[/tex]
However, none of the options closely match this, so I will refrain from choosing.The number of decades between 1890 to 1980 can be calculated as:
[tex]1980 - 1890 = 90 \text{ years}[/tex]
Since one decade is 10 years, there are:
[tex]\frac{90}{10} = 9 \text{ decades}[/tex]
Therefore, the answer is B. 9.To find the distance traveled with a speed of 67 km/h in 3 hours:
[tex]\text{Distance} = \text{Speed} \times \text{Time} = 67 \times 3 = 201 \text{ km}[/tex]
So, the answer is B. 201 km.George is facing North. Turning two right angles anticlockwise gets him facing:
[tex]2 \times 90° = 180°[/tex]
Turning 180° anticlockwise from North leads to facing South.
Therefore, the answer is B. South.If Isheanesu spent [tex]\frac{1}{3}[/tex] on food and [tex]\frac{1}{4}[/tex] on clothes, the amount of money spent is [tex]\frac{1}{3} + \frac{1}{4} = \frac{4}{12} + \frac{3}{12} = \frac{7}{12}[/tex].
Therefore, the amount left is [tex]\frac{5}{12}[/tex] of the total.
Thus,
[tex]\frac{5}{12} \text{ of the total} = 90[/tex]
[tex]12 \times 90 = 1080[/tex]
[tex]\text{Total} = \frac{1080}{5} = 216[/tex]
None of the given options match, so I'll refrain from choosing.To convert [tex]\frac{7}{25}[/tex] to a percentage:
[tex]\frac{7}{25} \times 100\% = 28\%[/tex]
Therefore, the answer is A. 28%.To determine the numbers which are not prime:
- 19 is prime
- 29 is prime
- 21 is not prime (as it can be divided by 3 and 7)
- 23 is prime
Therefore, the answer is C. 21.
