Kehinde pays $1870 in rent every month. This amount is $80 more than twice what his brother Azarias pays for rent. How much does Azarias pay for rent?
Answer:
Step-by-step explanation:
Let's denote the amount Azarias pays for rent as "x." According to the given information, Kehinde pays $80 more than twice Azarias' rent. Therefore, we can set up the following equation:
2x + $80 = $1870
To solve for x, we can subtract $80 from both sides of the equation and then divide by 2:
2x = $1870 - $80
2x = $1790
x = $1790 / 2
Evaluating the expression:
x = $895
Therefore, Azarias pays $895 for rent.

Martina, a 3-year-old with flaming red hair and bright blue eyes, is admitted to the pediatric unit w
bronchitis. In addition to her medical condition, Martina has autistic disorder. Martina does not seem
nurse's presence in the room but is intensely occupied with a blue stuffed dog. The nurse is prepar
ister scheduled oral medications to the child. Martina's mother is present in the room.
What approach would help the nurse to establish a trusting relationship with Martina
To establish trust with Martina, the nurse should show respect, use non-verbal communication, incorporate play, involve the parent, and individualize the approach.
To establish a trusting relationship with Martina, the nurse can employ several approaches:
Respect and empathy: The nurse should approach Martina with genuine respect and empathy, recognizing her unique needs and individuality. This can be conveyed through a calm and patient demeanor.
Non-verbal communication: Since Martina may not be responsive to verbal cues, the nurse can utilize non-verbal communication to establish connection and trust. This can include maintaining eye contact, using gentle touch, and respecting Martina's personal space.
Play and familiar objects: Given Martina's engagement with the blue stuffed dog, the nurse can incorporate play into their interactions. Bringing familiar objects or toys that Martina finds comforting can help create a sense of familiarity and security.
Parental involvement: Involving Martina's mother in the care process can be beneficial. The nurse can communicate with the mother, seek her input, and involve her in the administration of medications. This helps build trust not only with Martina but also with her caregiver.
Individualized approach: Recognizing Martina's autistic disorder, the nurse should tailor their approach to her specific needs. Understanding her sensory sensitivities and preferences can help create a safe and comfortable environment.
By implementing these strategies, the nurse can foster trust and a positive therapeutic relationship with Martina, promoting her overall well-being and care.

Answer:
-1/2
Step-by-step explanation:
To find f(f^-1(-1/2)), we need to first find the inverse of f, which is denoted as f^-1. The inverse of a function f is another function that undoes the effect of f. In other words, if y = f(x), then x = f^-1(y).
The inverse of f is given by:
f^-1(y) = (y - 5) / 2
Now we can substitute -1/2 for y in this expression to find f^-1(-1/2):
f^-1(-1/2) = (-1/2 - 5) / 2
f^-1(-1/2) = (-11/2) / 2
f^-1(-1/2) = -11/4
Now that we have found f^-1(-1/2), we can substitute this value into the original function f to find f(f^-1(-1/2)):
f(f^-1(-1/2)) = f(-11/4)
f(f^-1(-1/2)) = 2(-11/4) + 5
f(f^-1(-1/2)) = -11/2 + 5
f(f^-1(-1/2)) = -1/2
Therefore, f(f^-1(-1/2)) = -1/2
Main Street Ice Cream Company uses a plantwide allocation method to allocate overhead based on direct labor-hours at a rate of $3 per labor-hour. Strawberry and vanilla flavors are produced in Department SV. Chocolate is produced in Department C. Sven manages Department SV and Charlene manages Department C. The product costs (per thousand gallons) follow.
Strawberry Vanilla Chocolate
Direct labor (per 1,000 gallons) $ 757 $ 832 $ 1,132
Raw materials (per 1,000 gallons) 807 507 607
Required:
a. If the number of hours of labor per 1,000 gallons is 60 for strawberry, 65 for vanilla, and 50 for chocolate, compute the total cost of 1,000 gallons of each flavor using plantwide allocation.
b. Charlene's department uses older, outdated machines. She believes that her department is being allocated some of the overhead of Department SV, which recently bought state-of-the-art machines. After she requested that overhead costs be broken down by department, the following information was discovered:
Department SV Department C
Overhead $ 90,972 $ 27,750
Machine-hours 25,270 36,700
Labor-hours 25,270 18,500
Using machine-hours as the department allocation base for Department SV and labor-hours as the department allocation base for Department C, compute the allocation rate for each.
c. Compute the cost of 1,000 gallons of each flavor of ice cream using the department allocation rates computed in requirement (b) if the number of machine-hours for 1,000 gallons of each of the three flavors of ice cream are as follows: strawberry, 60; vanilla, 65; and chocolate, 157. Direct labor-hours by product remain the same as in requirement (a).
a. Using plantwide allocation based on direct labor-hours at a rate of $3 per labor-hour:
Strawberry: $1,744 per 1,000 gallons
Vanilla: $1,534 per 1,000 gallons
Chocolate: $1,889 per 1,000 gallons
b. Allocation rates:
Department SV: $3.60 per machine-hour
Department C: $1.50 per labor-hour
c. Using department allocation rates:
Strawberry: $1,780 per 1,000 gallons
Vanilla: $1,573 per 1,000 gallons
Chocolate: $1,886 per 1,000 gallons
a. To compute the total cost of 1,000 gallons of each flavor using plantwide allocation, we need to allocate overhead based on direct labor-hours at a rate of $3 per labor-hour.
Strawberry:
Direct labor cost: $757 per 1,000 gallons
Labor-hours: 60 per 1,000 gallons
Overhead allocation: $3 per labor-hour * 60 labor-hours = $180
Raw materials cost: $807 per 1,000 gallons
Total cost of 1,000 gallons of strawberry flavor:
Direct labor cost + Overhead allocation + Raw materials cost = $757 + $180 + $807 = $1,744
Vanilla:
Direct labor cost: $832 per 1,000 gallons
Labor-hours: 65 per 1,000 gallons
Overhead allocation: $3 per labor-hour * 65 labor-hours = $195
Raw materials cost: $507 per 1,000 gallons
Total cost of 1,000 gallons of vanilla flavor:
Direct labor cost + Overhead allocation + Raw materials cost = $832 + $195 + $507 = $1,534
Chocolate:
Direct labor cost: $1,132 per 1,000 gallons
Labor-hours: 50 per 1,000 gallons
Overhead allocation: $3 per labor-hour * 50 labor-hours = $150
Raw materials cost: $607 per 1,000 gallons
Total cost of 1,000 gallons of chocolate flavor:
Direct labor cost + Overhead allocation + Raw materials cost = $1,132 + $150 + $607 = $1,889
b. To compute the allocation rate for each department, we will divide the overhead cost by the corresponding allocation base.
Allocation rate for Department SV:
Overhead: $90,972
Machine-hours: 25,270
Allocation rate = Overhead / Machine-hours = $90,972 / 25,270 = $3.60 per machine-hour
Allocation rate for Department C:
Overhead: $27,750
Labor-hours: 18,500
Allocation rate = Overhead / Labor-hours = $27,750 / 18,500 = $1.50 per labor-hour
c. To compute the cost of 1,000 gallons of each flavor using the department allocation rates, we will multiply the allocation rate by the corresponding allocation base for each flavor.
Strawberry:
Machine-hours: 60 per 1,000 gallons
Allocation rate for Department SV: $3.60 per machine-hour
Overhead allocation: $3.60 per machine-hour * 60 machine-hours = $216
Direct labor cost: $757 per 1,000 gallons
Raw materials cost: $807 per 1,000 gallons
Total cost of 1,000 gallons of strawberry flavor:
Direct labor cost + Overhead allocation + Raw materials cost = $757 + $216 + $807 = $1,780
Vanilla:
Machine-hours: 65 per 1,000 gallons
Allocation rate for Department SV: $3.60 per machine-hour
Overhead allocation: $3.60 per machine-hour * 65 machine-hours = $234
Direct labor cost: $832 per 1,000 gallons
Raw materials cost: $507 per 1,000 gallons
Total cost of 1,000 gallons of vanilla flavor:
Direct labor cost + Overhead allocation + Raw materials cost = $832 + $234 + $507 = $1,573
Chocolate:
Labor-hours: 157 per 1,000 gallons
Allocation rate for Department C: $1.50 per labor-hour
Overhead allocation: $1.50 per labor-hour * 157 labor-hours = $235

The value of x rounded to the nearest whole number is 920.
What are Percentages?A percentage is a way to describe a part of a whole such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that the number 312.8 is 34% of x.
Thus, we can write,
34% of x = 312.8
(34/100) × x = 312.8
Now, Multiply both the sides of the equation by 100,
(34/100) × x × 100 = 312.8 × 100
Now, Divide both the sides of the equation by 34,
[(34/100) × x × 100] ÷ 34 = (312.8 × 100) ÷ 38
x = (312.8 × 100)/34
x = 920

What are the theorems of parallel lines?The same-side interior angles are additional if a transversal connects two parallel lines. Alternate interior angles are equivalent if a transversal connects two parallel lines. Corresponding angles are equal.
a) Given line PQ is parallel to ST.
One of the theorems of parallel lines is, Corresponding angles are equal.
Here the corresponding angles are ∠a, ∠b.
so, ∠a=∠b
∴∠b=64°
b) It is given that lines B and C are parallel, according to one of the theorems of parallel lines, vertically opposite angles are equal. So, the angle opposite to 65° is also equal to 65°. Sum of the angles suspended by a line on another line is 180°. Therefore the other angle in the triangle is 180°-130°=50°.
Since the sum of interior angles in a triangle is 180°, the angle q will be:
∠q= 180°-(65°+50°)
∠q= 65°.
Vertically opposite angles are equal, therefore ∠q=∠r=65°.
∠s=180°-(65°+65°)
∠s=50°.
Corresponding angles are equal, therefore
130°=65°+∠t
∠t=65°.
c) Given lines A, and B are parallel. We know that the Corresponding angles are equal, therefore
3m=4m-24
⇒m=24
Therefore ∠B=4(24)-24
∠B=72 degrees.

\(undefined\)Solve (x+1)2 =13/4 using the square root property
Answer:
Starting with the equation:
(x + 1)^2 = 13/4
We can use the square root property, which states that if a^2 = b, then a is equal to the positive or negative square root of b.
Taking the square root of both sides, we get:
x + 1 = ±√(13/4)
Simplifying under the radical:
x + 1 = ±(√13)/2
Now we can solve for x by subtracting 1 from both sides:
x = -1 ± (√13)/2
Therefore, the solutions to the equation are:
x = -1 + (√13)/2 or x = -1 - (√13)/2
