Julie’s employer does a 50% match to its employees’ contributions to their 401k accounts. If Julie puts $12,000 in her 401k, what is her balance after her employer’s contribution is added?
A
$ 6,000
B
$ 12,000
C
$ 18,000
D
$ 24,000
Answer: C 18000
Step-by-step explanation:
Julie contributes $12,000 to her 401k and her employer matches 50% of this amount, contributing an additional $6,000. Thus, the total balance in Julie's 401k after the employer's contribution is added is $18,000.
The question involves calculating the total balance in Julie's 401k account after her employer's contribution. Julie contributes $12,000 to her 401k, and her employer offers a 50% match on contributions. To find the total balance, first calculate the employer's contribution, which is 50% of Julie's contribution, so $12,000 x 0.5 = $6,000.
Adding the employer's contribution to Julie's contribution gives us the total balance in the 401k account. Therefore, $12,000 (Julie's contribution) + $6,000 (employer's match) = $18,000.

The data given for a football kicked from the field follows a quadratic model, h(x) = - 3x2 + 18x +7 . Where h(t) is the height in feet and t is the in seconds. Using this model, at what time will the ball reach its maximum height
Answer:
The time at which the ball will reach its maximum height is t= 3 seconds.
Step-by-step explanation:
To find the the time at which the ball will reach its maximum height, we need to solve the model given - 3x2 + 18x +7
since h(t) is the height given we can re-write the equation as:
h(t)= -3(t)² + 18t +7
Differentiating the above equation
[tex]\frac{dt}{dh} = -6t + 18[/tex]
When the ball is at maximum height [tex]\frac{dt}{dh}=0[/tex]
0=-6t+18
-18 = -6t
=> t= -18/-6
=> t= 3
the time at which the ball will reach its maximum height is t= 3 seconds.
We can find the maximum height by putting value of t in equation:
h(3) = -3(3)²+ 18(3) +7
h(3)= -27 + 54 + 7
h(3)= 34 ft
Answer:
three seconds

The cone shown has a diameter of 18 meters and a slant height of 15 meters .Which choice is closest to the lateral surface area? Use 3.14 to approximate.
Answer:
Cone diameter = 18 m therefore radius = 9 m
Lateral Area = PI * radius * slant height
Lateral Area = 3.14 * 9 * 15 = 423.90 square meters
Step-by-step explanation:
Final answer:
The lateral surface area of a cone with a diameter of 18 meters and a slant height of 15 meters is approximately 423.9 square meters, calculated using the formula LSA = πrl with π approximated as 3.14.
Explanation:
The student is asking about finding the lateral surface area of a cone with a given diameter and slant height, where the diameter is 18 meters and the slant height is 15 meters. To find the lateral surface area (LSA) of a cone, the formula LSA = πrl can be used, where 'r' is the radius of the base and 'l' is the slant height of the cone. Since the diameter is 18 meters, the radius is half of that, which is 9 meters. Using 3.14 as the approximation for π (pi), we can calculate the lateral surface area.
The calculation would be as follows:
Find the radius (r): Diameter / 2 = 18m / 2 = 9m.
Use the formula LSA = πrl: LSA = 3.14 * 9m * 15m.
Calculate the LSA: LSA = 3.14 * 135m².
LSA = 423.9m², which is the lateral surface area of the cone.
Therefore, 423.9 square meters is the closest approximation to the lateral surface area of the given cone.

Six more than -7 times a number is 34. What is the number?
Let the mystery number be represented by n.
The equation is 6 + (-7)n = 34
TRUE or FALSE: The mystery number is -7.
Answer:
False
Step-by-step explanation:
6 + (-7)n = 34
Plug in -7 for n and see if it's true:
6 + (-7)(-7) = 34
6 + 49 = 34

Estimate the difference. 10 1/9 - 5 14/15
To estimate the difference between 10 1/9 and 5 14/15, we round them to the nearest whole numbers, 10 and 6, respectively, and then subtract to get an estimated difference of 4.
To estimate the difference between the two numbers 10 1/9 and 5 14/15, we can round them to easier numbers to subtract. 10 1/9 is approximately 10, and 5 14/15 is close to 6 because 14/15 is almost a whole number. Now, we can simply subtract 6 from 10.
10 - 6 = 4
So, the estimated difference between 10 1/9 and 5 14/15 is about 4.
