Step-by-step explanation:
Your problem → 5y+5/2 / 25y-20/40y^2-32y
5y+5/2÷25y-20/40y^2-32y
=5⋅y+5/2÷25×y-20/40×y^2-32×y
=5y+5/2÷25×y-20/40×y^2-32y
=5y+5/2×1/25×y-20/40×y^2-32y
=5y+y/10-20/40×y^2-32y
=5y+y/10-y^2/2-32y
=5y×10+y-y^2×5-32y×10 ÷ 10
=50y+y-5y2-320y ÷ 10

Which of the following is the product of the rational expressions shown below?
Answer:
(3x^2+6x)/(x^2-16)
Step-by-step explanation:
When multiplying fractions you just go straight accross
this means that our fraction is equal to
((x+2)(3x))/((x-4)(x+4))
The numerator is quite easy 3x(x+2)=3x^2+6x
The second one is a little tough at first and if you need help I would reccomend using khan academy
but pretty much you get x^2-16

Millie expected 20 friends to show up to her birthday party, but 24 attended. What was
her percent error? Round to the nearest percent.
Answer:
Her percent error was: ≈ 17% (whole percent)
Step-by-step explanation:
Given
Approximate value = 20 friends
Exact Value = 24 friends
To determine
Percent error
Using the formula to calculate the Percent error
Percent error = | Approximate Value| - Exact Value | / | Exact value | × 100
= | 20 - 24 | / | 24 | × 100
= | - 4 | / | 24 | × 100
Apply absolute value: |-a| = a, a>0
= 4/24 × 100
= 16.67 %
≈ 17% (whole percent)
Thus, her percent error was: ≈ 17% (whole percent)
Meyer used 8 loads of gravel to cover 2/5 of his driveway. How many loads of gravel will he need to cover his entire driveway?
Answer:Meyer uses 2.5 loads
Step-by-step explanation:Why does he use 2.5? Because, he has 8 loads and with 1 load he covers 2/5 of his driveway so 2 loads covers 4/5 and 2.5 loads cover 5/5 of his driveway
Al, Tom and Joe share €3000.
The ratio of the amount Al gets to the amount Tom gets is in the
ratio 5:4
Joe gets 1.5 times the amount Tom gets.
Work out the amount of money that Tom gets.
Answer:
Tom's share = €800
Step-by-step explanation:
Given that:
Amount shared by Al, Tom and Joe = €3000
Ratio of Al's share to Tom's share = 5 : 4
Joe's share = 1.5(Tom's share) = 1.5(4) = 6
Therefore,
Ratio of Al, Tom and Joe = 5 : 4 : 6
Let,
x be the number of times of amount each get.
5x + 4x + 6x = 3000
15x = 3000
Dividing both sides by 15
[tex]\frac{15x}{15}=\frac{3000}{15}\\x=200[/tex]
Tom's share = 4x = 4(200) = €800
Hence,
Tom's share = €800

Jackson is two times older than Shelly. If the sum of their ages is 18, how old is Jackson?
Answer:
Jackson is 12 and Shelly is 6.
Step-by-step explanation:
Since we know Jackson is two times older than Shelly, it only makes since for our answer to be 12.
to find this you can make two circles and add dashes in each until you reach 18, but add 2 to Jackson to each 1 you put for Shelly.

A large nest of recently hatched bald eagles is located at the top of the Eiffel Tower (which is 324 meters tall) and is attracting much attention from the many visitors to the city of Paris. A tourist is standing at ground level, 54 meters across from the Eiffel Square, aiming her binoculars at the nest. At what angle should she set her binoculars in order to see the next? Round your answer to the nearest tenth of a degree.
9514 1404 393
Answer:
80.5°
Step-by-step explanation:
The applicable trig function is the tangent.
Tan = Opposite/Adjacent
In this scenario, the side opposite the angle is the tower height, 324 m. The side adjacent is the distance to the tower, 54 m. Then the angle α is related by ...
tan(α) = 324/54
The value of the angle with this tangent is found using the arctangent function:
α = arctan(324/54) ≈ 80.5°
She should set her binoculars to 80.5°.
What is the total volume of all four lockers if one side of a locker is 2 feet long?
Answer:
32ft³
Step-by-step explanation:
Let the shape of the locker be cubic in nature.
Volume of a cube = L³
L is the side length of one of the lockers
Volume of four lockers = 4L³
If one side of the locker is 2feet long, then L = 2ft
Substitute into the formula;
Volume of four lockers = 4(2)³
Volume of four lockers = 4(8)
Volume of four lockers = 32ft³
Hence the total volume of all four lockers is 32ft³
To solve the problem we will calculate the volume of a single locker first.
The volume of the 4 lockers is equal to 32 ft³.
Given to us
one side of a locker is 2 feet long
Assumpting that the locker is of cube shape.
Length of the side of a LockerAs it is given that the side of the locker is 2 feet long, and we know that all the sides of a cube are of the same length, therefore, the length of the side of the cube is 2 feet.
What is the volume of the Locker?We know that the shape of the locker is cubic in nature, therefore,
The volume of the locker = Volume of the Cube
= (Side of the cube)³
= (2)³ = 8 ft³
Thus, the volume of a cubic locker is 8 ft³.
What is the volume of 4 such lockers?We have already calculated the volume of a locker, therefore, the volume of 4 such lockers will be 4 times the volume of a locker,
The volume of 4 lockers = 4 x volume of a lockers
= 4 x 8 ft³
= 32 ft³
Hence, the volume of the 4 lockers is equal to 32 ft³.
