The list shows the numbers of employees in the seven departments at a company.
14, 23, 54, 30, 26, 17, 26
What is the range of the numbers of employees in these departments?
Responses
A 4040
B 99
C 6868
D 12
The range of the numbers of employees in these departments can be calculated as follows:
Maximum number of employees = 54
Minimum number of employees = 14
Range = Maximum number of employees - Minimum number of employees
Range = 54 - 14
Range = 40
Therefore, the range of the numbers of employees in these departments is 40. Answer: D.
The area of a rectangle is 55.5 square inches. The height of the rectangle is 15 inches. What is the length of the base of the rectangle in inches?
Responses
A 40.5 in40.5 in
B 6.5 in6.5 in
C 832.5 in832.5 in
D 3.7 in
We can use the formula for the area of a rectangle:
Area = base x height
Substituting the given values:
55.5 = base x 15
Solving for the base:
base = 55.5 ÷ 15
base = 3.7 inches
Therefore, the length of the base of the rectangle is 3.7 inches. Answer: D.
Which expression is equivalent to 3 (4 + 5) - 2 × 62
Responses
A 17 - 122
17 - 12 2
B 12 + 6412 + 64
C 27 - 2 × 1227 - 2 × 12
D 3(9) - 2 × 36
We can use the order of operations (PEMDAS) to simplify the expression:
3(4 + 5) - 2 × 6²
= 3(9) - 2 × 36 (Calculate 4 + 5 = 9, and 6² = 36)
= 27 - 72 (Multiply 2 by 36, and then subtract from 3 times 9)
= -45
Therefore, the expression 3(4 + 5) - 2 × 6² is equivalent to -45. Answer: none of the above.
Reggie writes the expression m + 8 × (2/3). Which expression is equivalent to the one Reggie writes?
Responses
A m + (8×3 ÷ 2)m + (8×3 ÷ 2)
B 8 + m(2 ÷ 3)8 + m(2 ÷ 3)
C (m+8)(2 ÷ 3)(m+8)(2 ÷ 3)
D (8×2 ÷ 3) + m
We can use the order of operations (PEMDAS) to simplify the expression m + 8 × (2/3) by performing the multiplication before the addition:
m + 8 × (2/3) = m + (8 × 2) ÷ 3 = m + 16/3 = (3m + 16)/3
Therefore, the expression equivalent to m + 8 × (2/3) is (3m + 16)/3.
Answer: none of the above.
A grocery clerk put only packages of flour tortillas and packages of corn tortillas on a shelf. The ratio of the number of flour tortillas to the number of packages on the shelf was 5 to 9. Which number could be the number of packages of corn tortillas the clerk put on the shelf?
Responses
A 1818
B 2323
C 3232
D 14
If the ratio of the number of flour tortillas to the number of packages on the shelf was 5 to 9, then we can write it as:
5x : 9x
where x is a common factor.
The total number of packages on the shelf is:
5x + 9x = 14x
So, the ratio of the number of packages of corn tortillas to the total number of packages on the shelf is:
9x : 14x
The number of packages of corn tortillas could be any multiple of 9, as long as it is not a multiple of 14 (otherwise the ratio would be different).
Therefore, the only number that could be the number of packages of corn tortillas the clerk put on the shelf is 23.
Answer: B.
On Tuesday 27% of the customers who bought gas at a gas station made additional purchases. There were 300 customers who bought gas. How many of these 300 customers made additional purchases?
Responses
A 219219
B 8181
C 2727
D 273273
If 27% of the 300 customers made additional purchases, we can find the number of customers who made additional purchases by multiplying the percentage as a decimal by the total number of customers:
0.27 x 300 = 81
Therefore, 81 of these 300 customers made additional purchases. Answer: B.
Marty used a thermometer to record temperatures of -3.4° Celsius and 1.6° Celsius. Which temperature in degrees Celsius falls between the two temperatures Marty recorded?
Responses
A 1.8°C1.8°C
B -2.6°C-2.6°C
C -5.4°C-5.4°C
D 3.9°C
The temperature that falls between -3.4°C and 1.6°C will be greater than -3.4°C but less than 1.6°C.
Looking at the answer choices:
A. 1.8°C is greater than 1.6°C, therefore it can't be the answer.
B. -2.6°C is less than -3.4°C, therefore it can't be the answer.
C. -5.4°C is less than -3.4°C, therefore it can't be the answer.
D. 3.9°C is greater than 1.6°C, therefore it can't be the answer.
Therefore, none of the answer choices are correct.
which one correct Marty used a thermometer to record temperatures of -3.4° Celsius and 1.6° Celsius. Which temperature in degrees Celsius falls between the two temperatures Marty recorded?
Responses
A 1.8°C1.8°C
B -2.6°C-2.6°C
C -5.4°C-5.4°C
D 3.9°C
None of the answer choices are correct as explained before.
it has to be one correct
I apologize for the confusion. However, none of the answer choices is correct as all of them are either greater than 1.6°C or less than -3.4°C. Therefore, there is no temperature in degrees Celsius that falls between the two temperatures Marty recorded.
what is the value of 5/6 divided by 15/16
A.25/32
B.2/5
C.8/9
D.3/10
To divide two fractions, we multiply the first fraction by the reciprocal of the second fraction.
So,
5/6 ÷ 15/16 = 5/6 x 16/15
We can simplify by reducing 16/15 to 8/15:
5/6 x 16/15 = 5/6 x 8/15 = 2/6 = 1/3
Therefore, the value of 5/6 divided by 15/16 is 1/3.
Answer: None of the above.
IT WAS TO BEEN ONE
I apologize for the mistake in my previous response. The correct answer to the question "What is the value of 5/6 divided by 15/16?" is option A.
To divide fractions, we multiply the numerator of the first fraction by the denominator of the second fraction and the denominator of the first fraction by the numerator of the second fraction.
So,
5/6 ÷ 15/16 = 5/6 x 16/15
We can simplify by reducing 5 and 15 by 5, and then multiplying the resulting fractions:
5/6 x 16/15 = 1/2 x 16/3
Multiplying the numerators and the denominators separately:
1/2 x 16/3 = (1 x 16) / (2 x 3) = 16/6
Simplifying by dividing both numerator and denominator by 2:
16/6 = 8/3
Therefore, the value of 5/6 divided by 15/16 is 8/3.
