Answer:
The insulation fee for 175 square feet of carpet is $237.
Step-by-step explanation:
The amount of money, f(x), that it cost to purchase x square feet of the carpet is:
f(x)= 8x
The insulation fee,g(x), is $125 more than 8% of the cost of the carpet,f(x), we have
g(x)=8% of f(x)+125
[tex]\Rightarrow=\frac{8}{100}\times (8x)+125[/tex]
[tex]\Rightarrow=0.64x+125[/tex]
The insulation fee for 175 square feet of carpet,
i.e for x=175
[tex]g(x=175)=0.64\times175+125=237[/tex]
Hence, the insulation fee for 175 square feet of carpet is $237.

The observatory in the John Hancock Center in Chicago is located in the top floor, 900 feet above the ground. The express elevator travels nonstop from the ground floor to the observatory on the top floor at a rate represented by the equation y=30x, where y is the height, in feet, and x is the number of seconds.
Answer:
Step-by-step explanation:
Given the rate at which the elevator travels modeled by the expression;
y = 30x where y is the height, in feet, and x is the number of seconds.
If the observatory in the John Hancock Center in Chicago is located in the top floor, 900 feet above the ground, we can calculate the time taken to reach the top floor by substituting y = 900 into the equation and solve for x as shown;
y = 30x
900 = 30x
Rearrange
30x = 900
Divide both sides by 30
30x/30 = 900/30
x = 30
Hence it takes 30seconds for the elevator to reach the top floor
Rico bicycles at an average speed of 13.5 miles per hour. What distance will Rico bicycle in 3.5 hours? Rico will bicycle 13.5 × 3.5 = 47.25 miles in 3.5 hours. Use estimation to show that the above result is reasonable. Part 1 out of 2 Round 13.5 to and 3.5 to .
Answer:
47.25 milesStep-by-step explanation:
Speed = Distance/Time
Given
Speed = 13.5miles/hour
Time taken = 3.5hours
From the formula;
Distance = Speed * Time
Substitute the given parameters into the resulting equation
Distance = 13.5 * 3.5
Distance = 47.25miles
Hence the distance that Rico bicycle covered is 47.25miles

Two fitness clubs are asding new members. Fitness club A cutrently has 450 memebers and adds 15 nee memeners each month. Fitness club B currently has 400 members amd adds 25 new members each month. After how many months will fitness club A and B have the samr number of members?
Answer:
It will take 5 months for the two fitness clubs to have the same number of members
Step-by-step explanation:
Let the number of months it takes fitness club A and B to have the same number be = x
For the two clubs to have the same number in x months, that means we can set up an equation as follows
450 +15x = 400 + 25x
Grouping like terms
450 - 400 = 25x -15x
50 = 10x
x= 5
Therefore, it will take 5 months for the two fitness clubs to have the same number of members
1) Select the characteristics that are true of all parallelograms. Group of answer choices Opposite sides are never equal. Opposite angles are congruent (equal). A parallelogram can have more than 4 sides. Parallelograms have 4 sides. Opposites sides are parallel and equal in length.
Answer:
- Opposite angles are congruent (equal).
- Parallelograms have 4 sides
- Opposites sides are parallel and equal in length.
Step-by-step explanation:
A parallelogram is a quadrilateral and since quadrilaterals are fur sided figures, hence parallelograms are also four sided figures.
A parallelogram has its opposite side equal and parallel to each other with a slanting edge at two of its sides. Since its opposite sides are equal hence its opposite angles are also equal.
Parallelogram cannot have more than four sides because they are quadrilateral. Find the diagram of a parallelogram in the attached figure.
It can be seen from the attached figure that AB//CD and AD//BC
A store is marking down the price of a television 25 percent from the original price of $250. Which expression can be used to find the marked down price?
Answer:
250 × 0.25
Step-by-step explanation:
x/250 × 25/100
cross multiply
100x = 250 × 25
100x = 6250
divide by 100
x = 62.5
62.5 is how much the price got marked down
original price - marked down amount = new discounted price
250 - 62.5 = 187.5
$187.50 is now the actual price
As for which expression can be used to find the marked down price, none are listed in this problem and I'm assuming its a multiple choice question considering the wording of "which"
how i solved it is through cross multiplication but another way is by using the expression:
250 × 0.25
this is because 25% equals 0.25
In terms of the cosecant of a positive acute angle, what is the expression for csc 240°?
Answer:
- csc60°
Step-by-step explanation:
240° is in the third quadrant where csc < 0 , thus
csc240° = - csc(240 - 180)° = - csc60°
The expression for cosec 240° in terms of the cosecant of a positive acute angle is -cosec 60°.
What is the value of cosec (180°+α)?The value of cosec (180°+α) is -cosec α because (180°+α) lies in the third quadrant and in the third quadrant cosecant is negative.
So, cosec 240° = cosec (180°+60°)
cosec (180°+α) = -cosec α
So, cosec (180°+60°) = -cosec 60°
Thus, the expression for cosec 240° in terms of the cosecant of a positive acute angle is -cosec 60°.

The half-life of a certain radioactive material is 36 days. An initial amount of the material has a mass of 487 kg. Write an exponential function that models the

Answer:
a(t) = 487(1/2)^(t/36)a(5) = 442.302 kgStep-by-step explanation:
The exponential function for half-life problems is easily written using 1/2 as the base of the exponent.
present value = (initial value) × (1/2)^(t/(half-life))
Then the amount (a) remaining after t days is ...
a(t) = 487 × (1/2)^(t/36)
__
After 5 days, the amount remaining is ...
a(5) = 487×(1/2)^(5/36) ≈ 442.302 kg
_____
Some folks like their exponential function to be written using e as the base for the exponent. Here, that would be ...
a(t) = 487·e^(-0.019254t)
where the constant in the exponent is -ln(2)/36.

Is the ordered pair (–8, –7) a solution to the equation 3x + 10 = 2y? Show your work.
Answer:
yes
Step-by-step explanation:
Substitute x = - 8 and y = - 7 into the equation
If both sides are equal then (- 8, - 7) is a solution
left side = 3x + 10 = 3(- 8) + 10 = - 24 + 10 = - 14
right side = 2y = 2(- 7) = - 14
Since both sides are equal then (- 8, - 7) is a solution to the equation
