Answer:
7 years
Step-by-step explanation:
Malik's salary grows 25,500 in 12 years, so at the rate of ...
$25,500/(12 yr) = $2125/yr
To get his salary up to 40,000, it must grow by ...
40,000 -25,500 = 14,500
To grow that much will take ...
$14,500/($2125/yr) ≈ 6.82 yr
Malik must wait 7 years until his salary is at least $40,000.
_____
At the end of the 7th year, Malik's salary will be raised to ...
$25,500 + 7·2,125 = $40,375

A tree is growing at a constant rate. It is recorded that at the 7th year since it was planted it was at a height of 25 feet. It was recorded again at the 10th year since it was planted and it was at a height of 31 feet. How much does the tree grow every year?
9514 1404 393
Answer:
2 feet per year
Step-by-step explanation:
In the 3 years between the 7th and 10th, the tree grew 6 feet from 25 ft to 31 ft. The rate of growth is ...
(6 ft)/(3 yr) = (6/3) ft/yr = 2 ft/yr
Gia walked 1/4 mile from her house to the park, then 3/8 mile around the park, and then 1/4 mile back home. How many miles did she walk in all?
Answer:
7/8 miles
Step-by-step explanation:
Given data
From her house to the park= 1/4 miles
Around the park = 3/8 miles
back home= 1/4 miles
Total distance= 1/4+3/8+1/4
LCM= 8
=2+3+2/8
=7/8 miles

The school band is selling t-shirts for a fundraiser. The initial cost for a steamer to apply the decals is $100. It is predicted that the cost of material for each shirt is $12. The function that shows the band's average cost per t-shirt after x t-shirts are sold is:
Answer: Vertical asymptotes is x = 0 and the horizontal asymptotes is y = 12.
The average cost approaches to 12 when the number of shirts increases.
Step-by-step explanation:
Since we have given that
Initial cost for a steamer to apply the declas = $100
Cost of material for each shirt = $12
Function representing the band's average cost per t-shirt after x t-shirt are sold is given by:
We need to find the vertical asymptotes , horizontal asymptotes and the average cost to make a t-shirt approaches as the number of t-shirts increases,
For vertical asymptotes , we will make denominator equal to zero.
So, it will be
Thus, vertical asymptotes is x= 0.
Similarly,
For horizontal asymptotes, we first check the degree of both numerator and denominator.
Since we can see that both have the same degree i.e. 1.
So,
So, the horizontal asymptotes is y = 12.
When the number of shirts increases ,The average cost to make a T-shirt approaches is given by
Hence, the average cost approaches to 12 when the number of shirts increases.
Answer:
The vertical asymptote is x = 0
The horizontal asymptote is y = 12
The average cost to make a t-shirt approaches $12 as the number of t-shirts made increases.

Suppose you invest $2200 at an annual interest rate of 5.3% compounded continuously. How much will you have in the account after 7 years?
Step-by-step explanation:
step 1. Let's call the amount of money A.
step 2. A = A¡e^(rt) (continuously compounding equation)
step 3. A = A¡e^(rt). A¡ = initial amount. r = rate, t = time.
step 4. A = 2200e^((.053)(7)
step 5. A = $3188.20

What is the solution for an equation?The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of that variable would give a true mathematical statement.
We need to find the solutions of the equation 2(x + $3.00)= $34.00 ;
Now solving for x;
2(x + $3.00)= $34.00
Open the bracket;
2x + 6 = 34
Combine the like terms;
2x = 34 - 6
2x = 28
x = 14
Therefore, the equation 2(x + $3.00)= $34.00 has only one solution which is 14.

What angle relationship best describes angles AFC and DFB?
A) Adjacent angles
B) Complementary angles
C) Linear pairs
D) Vertical angles
Answer:
Vertical Angles
Step-by-step
I believe this is the case because since the angles intercept in order to form also it's the only answer that has to do with intercepting from what we can see from the diagram.
There are different types of relationships between angles including alternate, corresponding, vertical, adjacent, complementary and supplementary angles
The correct option for the relationship that best describes angles AFC and DFB is option D;
D) Vertical angles
The reason the chosen option is correct is as follows;
The given diagram shows line EF perpendicular to line AB and line CD crosses line AB at point F
Therefore, the angles ∠AFC and ∠DFB formed by lines AB and CD with their orientation in the order of their names are opposite to each other and other are known as vertical angles

Explanation
Given that the equation 9x+3y =12
Let 'x' be an independent variable and 'y' be the dependent variable then the function is of the form
y = f(x)
3 y = 12 - 9x

Marcos debe pintar 5/9 de la cubierta de un velero. Al acabar el día ha pintado 21/36 . ¿Ha conseguido cumplir su objetivo? ¿Ha pintado más? ¿Ha pintado menos?
Answer:
a) Have you managed to meet your goal?
Yes
b) Have you painted more? Have you painted less?
You have painted more.
Step-by-step explanation:
Marcos should paint 5/9 of the deck of a sailboat.
At the end of the day he painted 21/36.
Reducing this to the simplest form = 21/36
Dividing Numerator and Denominator by 3
= 7/12
Finding the difference between both fractions
= 7/12 - 5/9
The Lowest Common Denominator = 36
= 21 - 20/36
= 1/36
Therefore:
a) Have you managed to meet your goal?
Yes
b) Have you painted more? Have you painted less?
You have painted more.
