Work out cube root of 512 : reciprocal of 0.4. Give your answer in the form n : 1
Step-by-step explanation:
Thanks, so cube root of 512 is 8 and reciprocal of 0.4 is 2.5 then:
8 : 2.5 / divide both by 2.5 to get:
3.2 : 1 that's my answer right?
The correct form of the ratio of cube root of 512: reciprocal of 0.4 is 3.2:1
What is a cube root?
It is a number y such that y to the power 3 is equal to x.
How to find ratio?
We have to find the ratio of cube root of 512 and the reciprocal of 0.4 which will be as follows
cube root of 512: reciprocal of 0.4
8: 1/0.4
8=2.5
dividing by 2.5
3.2 : 1
Hence the ratio will be 3.2 :1 of cube root of 512 and the reciprocal of 0.4

Three years ago the sum of the ages of father and his son was
48 years and three years hence father's age will be three times
that of his son. Find the present ages of the father and his son.
Answer:
The father is 42 years old and the son is 12 years old.
Step-by-step explanation:
Since three years ago the sum of the ages of father and his son was 48 years, and three years hence father's age will be three times that of his are his, to find the present ages of the father and his are his, the following calculations must be performed:
F + S = 48
F + 6 + S + 6 = 3S
34 + 14 = 48 /// 34 + 6 = 40 --- 14 + 6 = 20 (x 3 = 60)
38 + 10 = 48 /// 38 + 6 = 44 --- 10 + 6 = 16 (x 3 = 48)
40 + 8 = 48 /// 40 + 6 = 46 --- 8 + 6 = 14 (x 3 = 42)
39 + 9 = 48 /// 39 + 6 = 45 --- 9 + 6 = 15 (x 3 = 45)
39 + 3 = 42
9 + 3 = 12
Therefore, the father is 42 years old and the son is 12 years old.

You have decided to look at a truck that is listed for $12000. It is a 2001 Dodge Ram, V8, 85,000
miles, automatio, extended cab, black exterior and interior, A/C works, and factory radio. After test-
driving the vehicle, you decide to purchase the vehicle.
7. Sales tax for the vehicle is 8%. Including sales tax, what will be the final cost
of the truck?
8. You decide to finance the vehicle for 5 years, what will be your monthly
payment on the
vehicle before the interest you owe on the loan? PLEASE HELPPP
Answer:
a. the final cost will be $12,960
b. your monthly payment will be $216
Step-by-step explanation:
a. if the sales tax is 8%, that means that you will need to pay 8 cents for every dollar of the original cost. you can find the total cost by multiplying 1.08 (108%) by 12,000 in order to get the original price PLUS the sales tax added on. Thus, leaving you with $12,960 as the final price.
b. to find the monthly payment, you will multiply the number of years the payment is spread out over (5) by the number of months in a year (12) in order to get 60 months in total. Then divide the $12,960 by 60 in order to get a final monthly payment of $216.

A vector is used to express a car's change in position, or displacement, by tracking its motion over a large area defined by a coordinate grid. If the car begins at (−3,−5) and ends at (5,9), which of these expresses the car's displacement in vector form?
A
(14,8)
B
(10,12)
C
(8,14)
D
(2,4)
Answer:
The correct answer is option C: (8, 14).
Step-by-step explanation:
The car's displacement in vector form can be found by subtracting the initial points from the final points.
Initial: (x₁, y₁) = (-3, -5)
Final: (x₂, y₂) = (5, 9)
For the x-coordinate, we have:
[tex] d_{x} = x_{2} - x_{1} = 5 - (-3) = 8 [/tex]
And for the y-coordinate, we have:
[tex] d_{y} = y_{2} - y_{1} = 9 - (-5) = 14 [/tex]
The car's displacement in vector form is:
[tex] d = (d_{x}, d_{y}) = (8, 14) [/tex]
Therefore, the correct answer is option C: (8, 14).
I hope it helps you!

Find a polynomial equation that has roots of -2 and double root 3
Answer:
x³ + 2x² -3x +6
Step-by-step explanation:
We need to find the polynomial whose roots are ,
-2 , √3 and √3.Say of we have zeroes as , α , β and γ , then the polynomial is ,
=> p(x) = k[ (x - α ) ( x - β) ( x - γ) ]
where k is constant. Substituting the respective values , we have ,=> p(x) = k [ ( x - (-2)) ( x - √3) ( x -√3)]
=> p(x) = k[ (x+2)(x² - 3)]
=> p(x) = k[ x(x² - 3) + 2(x² - 3) ]
=> p(x) = k[ x³ - 3x + 2x² - 6 ]
=> p(x) = k[ x³ + 2x² - 3x - 6 ]
Hence the cubic polynomial is x³ + 2x² - 3x + 6 .17x+15= 66 then what is the value of x

Step-by-step explanation:
use pythagorean theorem
a²+b²=c²
c=20
b=15
a²+225=400
a²=175
√(175) = 5√(7) = 13.23
The height of the kite is 13.23 meters.
What is Pythagoras' theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Given:
A boy is flying a kite.
The length of the string is 20 meters and the horizontal distance between the boy and the kite is 15 meters.
Assuming there is no slack in the string,
then the height of the kite is,
= √(20)² - (15)²
= 13.23 feet.
Therefore, the height is 13.23 meters.

To compute a student's Grade Point Average (GPA) for a term, the student's grades for each course are weighted by the number of credits for the course. Suppose a student had these grades: 3.5 in a 5 credit Math course 2.2 in a 2 credit Music course 2.5 in a 5 credit Chemistry course 3.2 in a 4 credit Journalism course What is the student's GPA for that term
Answer: 2.95
Step-by-step explanation:
The students GPA for the term will be calculated as the weighted score divided by the number of units. This will be:
= (3.5 × 5) + (2.2 × 2) + (2.5 × 5) + (3.2 × 4) / (5 + 2 + 5 + 4)
= (17.5 + 4.4 + 12.5 + 12.8) / 16
= 47.2 / 16
= 2.95
Therefore, the GPA is 2.95

Answer:
D. No solution
Step-by-step explanation:
Given
[tex]y = 3x + 7[/tex]
[tex]y = 3x + 2[/tex]
Required
The number of solutions
We have:
[tex]y = 3x + 7[/tex] and [tex]y = 3x + 2[/tex]
Equate both i.e.
[tex]y = y[/tex]
So, we have:
[tex]3x + 7 = 3x + 2[/tex]
Subtract 3x from both sides
[tex]3x -3x + 7 = 3x -3x + 2[/tex]
[tex]7 = 2[/tex]
The above is false
i.e. [tex]7 \ne 2[/tex]
Hence, the system has no solution
