A garden store bought a fountain at a cost of $995.66 and marked it up 100%. Later on, the store marked it down 25%. What was the discount price?
Answer:
Step-by-step explanation:
The discounted price of the fountain was $1493.49
Mark up percentage is given by:
Mark up percentage = [(selling price - cost price)/cost price] * 100%
Given the store cost price of $995.66 it was marked up 100%, hence:
Mark up percentage = [(selling price - cost price)/cost price] * 100%
100% = [(selling price - 995.66)/995.66] * 100%
1 = [(selling price - 995.66)/995.66]
Selling price = $1991.32
It was then marked down 25%, let x represent the discount price, hence:
-25% = [(x - 1991.32)/1991.32]*100%
-0.25 = (x - 1991.32)/1991.32
x = 1493.49
Therefore, the discounted price of the fountain was $1493.49

Which of these lengths CANNOT represent the sides of a triangle? {28, 30, 58} {32, 34, 60} {13, 20, 27} {2, 4, 5}
Answer:
[tex]A.\ {28, 30, 58}[/tex]
Step-by-step explanation:
Required
Which of the lengths do not form a triangle
To do this, we make use of triangle inequality theorem which states that.
[tex]a + b > c[/tex]
[tex]b + c > a[/tex]
[tex]a + c > b[/tex]
Where [tex]a,\ b\ and\ c[/tex] are the sides of the triangle.
So, we have:
[tex]A.\ {28, 30, 58}[/tex]
[tex]28 + 30 > 58[/tex] --- False
[tex]58 + 30 > 28[/tex] --- True

Answer:
70 degrees
Step-by-step explanation:
Angles 130 degrees and TUV are supplementary angles. Thus, the latter is (180 - 120), or 60, degrees. Now the sum of all three interior angles of this triangle must be 180 degrees: (60 + 50 + >TUV) = 180, so >TUV is 70 degrees (answer C).

Yolanda wants to solve the system shown below. 3x − 4y = 5 2x + 3y = −2 She decides to use the elimination method to eliminate the x variable. Describe how she can do this.
Answer:
x = 23, y = 16
Step-by-step explanation:
Yolanda wants to solve the system shown below. 3x − 4y = 5 2x + 3y = −2 She decides to use the elimination method to eliminate the x variable. Describe how she can do this.
Using Elimination method
3x − 4y = 5 ..... Equation 1
2x + 3y = −2....... Equation 2
We Multiply Equation 1 by 2 and Equation 2 by 3 to Eliminate x
6x - 8y = 10..... Equation 3
6x - 9y = -6...... Equation 4
We substract Equation 4 from Equation 3
y = 16
Solving for x , by Substituting 16 for y in Equation 2
3x − 4y = 5...... Equation 1
3x -4 × 16 = 5
3x - 64= 5
3x = 5 + 64
3x = 69
x = 69/3
x = 23
Therefore, x = 23, y = 16

Answer:
X = 1
Step-by-step explanation:
You first divide each side by 3 leaving you with X+5 = 6. Then you take the 5 to the other side leaving you with X=6-5 as the 5 changes from positive to negative. So 6-5=1 so X=1

Answer:
100
Step-by-step explanation:
Volume of the larger box (cuboid) = 10(Length)×10(width)×16(height)
= 1600 cubic in
Volume of smaller box = 2×2×4= 16 cubic in
Therefore, number of smaller boxes can could be fit inside larger box = 1600/16 = 100

The equation of the scatter plot trend line is y = -1700x + 32000 where y is the value of the car in dollars and x is the age of cars in years. Use the trend line equation to predict the value of a car after 7 years.
Answer:
20100
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Given equation
y = -1700x + 32000
Where x is the age of car and y is the value of the car.
Then value after 7 years can be calculated as follows,
y = -1700 (7) + 32000
y = -11900 + 32000
y = 20,100
So, the value of car after 7 years will be 20100.
At 3:25 p.m., a passenger train and a freight train both left Kalamazoo,
Michigan. Right now, the passenger train is 61.5 miles west of Kalamazoo.
The freight train is now 49.5 miles east of Kalamazoo. The passenger train
averages 16 miles per hour faster than the freight train. What time is it
now?
Answer:
4:10 PM
Step-by-step explanation:
The time at which the passenger train is 61.5 miles west of Kalamazoo and the freight train is now 49.5 miles east of Kalamazoo 4:10 pm
Formula for speedSpeed is the ratio of distance travelled to time taken. It is given by:
Speed = distance / time
Let a represent the speed passenger train and b for the freight train.
The passenger train averages 16 miles per hour faster than the freight train, hence:
a = b + 16 (1)
Also:
a = 61.5/t
t = 61.5/a
b = 49.5/t
t = 49.5/b
61.5/a = 49.5/b
61.5b = 49.5a (2)
From both equations:
a = 82 mph, b = 66 mph
t = 61.5/82 = 0.75 hour = 45 minutes
Time = 3:25 p.m + 45 minutes = 4:10 pm
The time at which the passenger train is 61.5 miles west of Kalamazoo and the freight train is now 49.5 miles east of Kalamazoo 4:10 pm

Answer:
x = 12
y = 6√3
Step-by-step explanation:
✅Apply the intersecting secant theorem to find x. Thus:
6(6 + x) = 7(7 + 8³/7)
Convert the mixed fraction to improper fraction
6(6 + x) = 7(7 + 59/7)
36 + 6x = 49 + 59
36 + 6x = 108
6x = 108 - 36
6x = 72
Divide both sides by 6
x = 72/6
x = 12
✅Apply the tangent-secant theorem to find y. Thus:
y² = 6(6 + x)
Plug in the value of x
y² = 6(6 + 12)
y² = 6(18)
y² = 108
y = √108
y = 6√3
