The linear equation that represents the distance (d) above ground level after t seconds is d = -2t + 28
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
The standard equation of a linear equation is:
y = mx + b
Where m is the rate of change (slope) while b is the y intercept.
Let d represent the distance that you are from ground level over time t seconds.
Suppose you are in a building at 28 feet above ground level and you take an escalator down to ground level. On the escalator, your distance above ground level changes by - 2 feet per second. Hence:
d = -2t + 28
The linear equation is d = -2t + 28

A tabletop in the shape of a trapezoid has an area of 5029 square cenimeters. Its longer base measures 123 cenimeters, and the shorter base is 65 cenimeters. What is the height?
Answer:
Length of height = 53.5 cm
Step-by-step explanation:
Given:
Area of trapezoid = 5,029 cm²
Length of longer base = 123 cm
Length of shorter base = 65 cm
Find:
Length of height
Computation:
Area of trapezoid = [(a+b)/2]h
5,029 = [(123 + 65)/2]h
5,029 = [(188)/2]h
5,029 = [94]h
Length of height = 53.5 cm

Você precisa colocar suas renas, Raposa, Trovão, Cometa e Relâmpago, em uma fila única para puxar o seu trenó. No entanto, Cometa e Raposa são melhores amigos e precisam ficar juntos. De quantas maneiras você pode organizar as renas?
Answer:
If the reindeer do not fight, there are 5!=120 ways to line them up in a straight line.
Out of these, Bloopin and Rudy are together in 4!=24 times. Similarly Rudy and Bloopin will be together 4!=24 times. So the number of ways they are not together is 120-24-24=72 ways.
Hope this helps. :)
Step-by-step explanation:
Spanish:
Si los renos no luchan, hay 5! = 120 formas de alinearlos en línea recta.
De estos, Bloopin y Rudy están juntos en 4! = 24 veces. De manera similar, Rudy y Bloopin estarán juntos 4! = 24 veces. Entonces, el número de formas en que no están juntas es 120-24-24 = 72 formas.

The clock shows the time ( 9:00 ) that Candace leaves for a bicycle ride. She rides for 1/2 hour.
Through how many degrees does the minute hand turn while Candace is on her ride?
Answer:
180°
Step-by-step explanation:
1/2 hour = 30 minutes
1 hour is 360° degrees.
1/2 hour = 360 ÷ 2 = 180°
Answer:
180
Step-by-step explanation:
because half a circle is 180 degrees and since 1/2 hour means she returns at 9:30 the minute hand would have to move half of a circle around the clock

Answer: x - 2.60(2) + x + x - 2.60
Step-by-step explanation:
Aleekah’s amount is x, as identified by the problem. If Barika earn less than 2.60 than Aleekah, then you would take away 2.60 from x, thus x - 2.60. If (x - 2.60) is how much Barika earned and James earn twice that amount, then he would have ((x - 2.60)*2)

Answer:
LatTisha works as a Lifeguard
Zack works as a clerk at a grocery store
Steve works as a food server
Mitchel is a construction worker
Step-by-step explanation:
The parameters of the question are;
The names of the four friends are; LaTisha, Zack, Steve, and Michelle
The jobs found are; Food server, Lifeguard, Construction worker, and Clerk at a grocery store
1. The food server person likes his work
2. Zack and the lifeguard have known each other for years
3. Mitchel and the lifeguard are outside most of the time
4. LaTisha and the person working construction met on their job last summer
5. Neither Zack nor the food server worker worked last summer
We have;
Using known names,
Famale names are; LaTisha and Michelle
Male names are; Steve and Zack
Therefore
The food server worker is a guy, not Zack but likely Steve
Mitchel works outdoors, therefore, she works in the other outdoor employment which is construction
The remaining two occupations are;
Lifeguard and Clerk at a grocery store
Given that Zack is not the lifeguard, we have;
Zack is the clerk at a grocery store
LatTisha is the Lifeguard

Write a function rule for the table.
A. p = 7.50h
B. p = h + 15
C. p = 15h
D. h = 7.50p
Answer:
p = 7.50h
I got this correct, the answer is A. p= 7.50h
Step-by-step explanation:
The answer would be d because every two hours someone works they get $15 and for the equation we must know how much they work for one hour so that it works with the equation (we'd have to simplify it down do how much paid up per hour). so half of 15 is 7.5 so the equation would be p=7.50h (standing for $7.50 per hour).
The correct answer is: [D]: " p = 7.50 h " .
________________________________________________
The pay, "p" , is a function of the hours worked.
When h = 2, (h = number of hours);
the pay, "p" , is equal to " 7.50 * 2 " = 15.00 dollars" ; as shown on table.
When h = 4 ; p = " 7.50 * 4 = 30.00 dollars" ; as shown on table .
When h = 6 ; p = " 7.50 * 6 = 45.00 dollars" ; as shown on table.
When h = 8 ; p = " 7.50 * 8 = 60.00 dollars" ; as shown on table.

$1210 is invested in an account earning 11.5% interest compounded monthly. What is the balance at the end of 13 years? Group of answer choices

Formula to be used,
Final amount = [tex]\text{Initial amount}\times (1+\frac{r}{n})^{nt}[/tex]
Here, n = number of compounding in a year
t = Duration of investment
Now we substitute the given values in the question.
Final amount = [tex]1210(1+\frac{0.115}{12})^{12\times 13}[/tex]
= [tex]1210(1.009583)^{156}[/tex]
