Mary deposits $550 in a savings account at 3% simple annual interest. The value of this account, v, is given by the function v = 550 + 16.5t, in which t is the number of years the money is in the bank. What is the domain & range of this function?
Answer: [tex]Domain = \{t: t\geq 0\}=[0,\infty)[/tex] and [tex]Range = \{v: v\geq 550\}=[550,\infty)[/tex].
Step-by-step explanation:
It is given that, the value of this account, v, is given by the function
[tex]v=550+16.5t[/tex]
where, t is the number of years the money is in the bank.
We need to find the domain & range of this function.
Domain is the set of input values. Here, the domain is number of years which cannot be negative. So,
[tex]Domain = \{t: t\geq 0\}=[0,\infty)[/tex]
Range is the set of output values. Here, the range is amount after simple interest which cannot be less than the principal value.
[tex]Range = \{v: v\geq 550\}=[550,\infty)[/tex]

4x+7 = 5(x-4)
Distribute
4x+7 = 5x-20
Subtract 4x from each side
4x+7-4x = 5x-4x-20
7 = x-20
Add 20 to each side
7+20 = x-20+20
27 =x
Answer:
x = 27
Step-by-step explanation:
Since they are corresponding they have to be equal.
4x+7 = 5(x-4)
4x+7 = 5x-20 distribute the 5
7 = 5x-4x-20 bring the 4x over
7 = x-20 simplify the x
7+20= x bring the twenty over
27=x

Answer:
I'm kind of confused what the question is asking. If they are asking for an expression to represent JL then the answer is 14x -32. If they want to know the distance between J and L then the answer is 66
Step-by-step explanation:
First I set the 2 equations equal to each other (5x-2 = 9x -30) and solved this to get x =7. (ANSWER ONE)
Next I plugged 7 into one of the equations (in this case either one will work bc JK and KL are the same distance. so I plugged 7 into the first one ( 5(7) -2 ) and I got 33. This means the distance of JK (and KL since they are equal) is 33.
Next I multiplied 33 by 2 since JL is JK and KL combined ( JK and KL are both 33 and therefore adding them together (multiplying 33×2) will give you the length of JL) and I got 66 (ANSWER 2)

A square garden has sides 100 ft long. You want to build a brick path along a diagonal of the square. How long will the path be? Round your answer to the nearest
foot.
The length of the diagonal of the square rounded to the nearest foot is 141.2 feet.
What are the dimensions of a square?The area of a square is a product of it's any two sides or a product of diagonals divided by two. If the side has a length then the diagonal is a√2.
The perimeter of a square is the sum of the lengths of all the sides.
Given, A square garden has sides 100 ft long.
Now, If we draw a diagonal it becomes a right-angled triangle with a height of 100 ft and a base of 100 feet.
Therefore, By applying Pythagoras' theorem we have,
The length of the diagonal is = √(100² + 100²).
= √(10000 + 10000).
= √(20000) feet.
= 141.42 Or 141 feet.

Plaz mark brainliest. I just need 2 more to raise my level.
Answer:
Yes unless the fraction is equal to a whole number or is an improper fraction
Step-by-step explanation:
A normal fraction like 2/4 is less than a whole number because a whole number is whole and a fraction is part of
Exceptions:
4/4 is a fraction but is also a whole number
any improper fraction ( a fraction not simplified)
5/4 it equals more than a whole number 1 1/4
So simplify the fraction and if it is equal to or more than a whole number you know, but if it is less than a whole number then you know it is less.

A lioness hunting antelope runs a distance of 60 m in 15 s. Then she stops to survey the herd for 20 s. Next, she trots for 25 s over 60 m around the edge of the herd. Finally, the lioness races after the antelope, traveling 120 m in 20 s. What is the average speed of the lioness?
Answer: The average speed is 3m/s.
Step-by-step explanation:
We can define the average speed as the quotient between the total distance traveled in a given period of time, and that period of time,
Here we have that:
d = distance
t = time.
"A lioness hunting antelope runs a distance of 60 m in 15 s"
1) d = 60m, t = 15s
"Then she stops to survey the herd for 20 s"
We add 0 meters to the distance, and 20 seconds to the time.
2) d = 60m + 0m, t = 15s + 20s = 35s
"she trots for 25 s over 60 m around the edge of the herd."
we add 60m to the distance, and 25s to the time
3) d = 60m + 60m = 120m, t = 35s + 25s = 60s.
"Finally, the lioness races after the antelope, traveling 120 m in 20 s"
we add 120m to the distance and 20s to the time.
4) d = 120m + 120m = 240m, t = 60s + 20s = 80s.
Then the average speed of the lioness in that period of time is:
S = 240m/80s = 3m/s

1. If Bob scored a 75 on a test with a mean of 75, what would his z-score be?
Answer:
the z score is 25
Step-by-step explanation:
since 75 needs 25 more for and 100%
The z-score of Bob if he scored 75 on a test that has a mean of 75 is: z-score = 0.
What is the Z-score?The z-score = (raw score - mean score)/standard deviation.
A z-score of 0 means the raw score is exactly average.
For a raw score of 75, where the average(mean) is 75, the z-score would definitely be 0.
Thus, Bob's z-score is 0.

Kreem starts with 70 flowers
He gives x amount of flower away
That leaves us with 70-x =2
Or 2+x=70
We can now rewrite the question to 70-2=x
Using this we see x, the amount of flowers given away, is 68.

Determine whether the description corresponds to an observational study or an experiment.Research is conducted to determine if there is a relation between stomach cancer and alcohol consumption.
Answer:
Observational
Step-by-step explanation:
Observational studies are studies that measure the outcome of events without the introduction of interventions. They are useful in the formation of a hypothesis. The experiment described above is an observational study that compares two groups so as to measure the predictors of an outcome. No intervention is introduced to influence the outcome of the research.
An experiment on the other hand is often organized as a randomized control trial where subjects are divided into groups and a placebo or control group is introduced to monitor the outcome of the study.

A school choir needs to make T-shirts for its 75 members and has set aside some money in their budget to pay for them. The members of the choir decided to order from a printing company that charges $3 per shirt, plus a $50 fee for each color to be printed on the shirts. (The fee applies to the order, not to individual shirts) Write an equation that represents the relationship between the number of T-shirts ordered, the number of colors on the shirts, and the total cost of the order. If you use variables, specify what they represent (define them).
Answer:
[tex]Equation = 225 + 50y[/tex]
Step-by-step explanation:
Given
Members = 75
Cost of Shirt = $3
Color = $50 on all shirts
Required
Determine an equation to represent the scenario
Represent the members with x
Such that:
[tex]x = 75[/tex]
First, we need to determine the total cost of ordering x shirts
A shirt costs $3;
So,
[tex]x\ shirts = 3 * x[/tex]
[tex]x\ shirts = 3 x[/tex]
Next, we determine the total cost of colors
Represent each color with y
[tex]1\ color = \$50[/tex]
[tex]y\ color = \$50 * y[/tex]
[tex]y\ color = 50 y[/tex]
The required equation is calculated as thus;
[tex]Equation = x\ shirts + y\ color[/tex]
[tex]Equation = 3x + 50y[/tex]
Substitute 75 for x
[tex]Equation = 3 * 75 + 50y[/tex]
[tex]Equation = 225 + 50y[/tex]
Answer:
50 + 3(B) + 50 + 3(R) + 50 + 3(Y) would be the equation.

A square room in your house has an area of 85 square feet. What is the approximate length of each side of the room?
Answer:
9.2 ft
Step-by-step explanation:
The area of a square is A = s^2 where s is the side length
A = s^2
85 = s^2
Take the square root of each side
sqrt(85) = sqrt(s^2)
sqrt(85) = s
9.219544457 =s
9.2 ft is about the length of each side
