Flavia bought a pair of rollerblades. The regular price was 129.50. They were bought for 40% off and the sales tax was 15%. Show all the steps...
Answer:
Here u go
Step-by-step explanation:
1. 40/100 × 129.50 = 51.80
2. 129.50 - 51.80 = 77.70
3. 15/100 × 77.70 = 11.66
4. 77.70 + 11.66 = 66.04
The final cost of the roller blades is $ 89.66
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total cost of purchase be = A
Now , the initial cost of roller blades = $ 129.50
The discount percentage of roller blades = 40 %
So , the equation will be
The cost of the roller blades after discount = 129.50 - ( 40/100 ) x 129.50
= 129.50 - 51.8
= $ 77.7
Now ,
The sales tax percentage of roller blades = 15 %
So , the equation will be
The cost of roller blades after sales tax = 77.7 + ( 15/100 ) x 77.7
= 77.7 + 11.655
= $ 89.655
Therefore , the final cost is A = $ 89.66
Hence , The final cost of the roller blades is $ 89.66

In a 33' by 69.7' room, what is the diagonal length from corner to corner along the floor?
Answer:
77.12 feets
Step-by-step explanation:
In a 33' by 69.7' room, what is the diagonal length from corner to corner along the floor?
Step one:
given data
Length of the room= 33 feets
width of the room = 69.7 feets
Required
The diagonal of the room
Step two:
from Pythagoras theorem
z^2= x^2+y^2
substitute
z^2= 33^2+ 69.7^2
z^2=1089+4858.09
z^2=5947.09
z=√5947.09
z=77.12 feets
Suppose y varies directly with x. Write a direct variation equation that relates x and y. Then find the value of y when x=16...
y=7 when x=2
Step-by-step explanation:
y = kx, where k is a real constant.
When x = 2, y = 7.
=> (7) = k(2), 2k = 7, k = 3.5.
Therefore when x = 16,
y = (3.5)(16) = 56.
The value of y is 56 when x is 16.
The formula for direct variation is y = kx
Using the known x and y solve for k:
7 = k2
Divide both sides by 2:
k =7/2 = 3.5
Now solve for y when x = 16:
y = 3.5(16)
y = 56
In a fish tank there are 10 clown fish, 4 angel fish, 6 puffer fish, and 5 eels. What is the probability of scooping out a clown fish on the second scoop after scooping out a clown fish on the first scoop and not replacing it
Answer:
3/8
Step-by-step explanation:
Given that
Number of clown fish = 10
Number of Angel fish = 4
Number of Puffer fish = 6
Number of Eels = 5
From the above, there exists 10 + 4 + 6 + 5 number of fishes
There exists 25 number of fishes.
Probability of picking a clown fish then is
C = 10 / 25
If the clown fish picked isn't replaced, then there exists 9 clown fishes, and 24 total fishes. This, the probability of picking another clown fish is
C = 9 / 24
C = 3 / 8
Thus, the answer is 3/8

Answer:
h = √65, length of diagonal = √117
Step-by-step explanation:
1) FE = DC since △FEA congruent to △CBD. Therefore FE per say = 23-15/2 = 4. Respectively we can find height "AE" using Pythagorean theorem;
AE = √(9)^2-(4)^2 = √81-16 = √65 units
h = √65
2) The diagonal of this rectangle forms two smaller triangles, each of which have legs of length 4 + 2 & 4 + 4 respectively. Use Pythagorean Theorem and determine the length of the diagonal;
Legs = 6 & 8
6^2 +9^2 = diagonal^2,
length of diagonal = √6^2 + 9^2
= √117 units

Sally's investment of £450 has gone up by 30 percent, while susie's investment of £650 has gone done by 10 percent.Who now has the larger amount of money
Answer:
Neither, they have the same amount now?
Step-by-step explanation:
Sally = £450 = 100%
Gone up by 30% so 100% + 30% = 130% = 1.3
£450 x 1.3 = £585
Susie = £650 = 100%
Gone down by 10% so 100% - 10% = 90% = 0.9
£650 x 0.9 = £585
