If y varies inversely as x and y=3 when x=8 what is x when y=4
I am Lyosha [343]

Answer:

x = 6

Step-by-step explanation:

y varies inversely as x

y = k × 1/x. {where k is a constant}

when y = 3, x = 8

Therefore 3 = k/8 and k is 24

y = 24/x

When y = 4,

4 = 24/x

4x = 24

(dividing both sides by 4)

x = 6

How can you use the prime factorization of the powers of ten to find the prime factorization of 270,000?
RoseWind [281]
Prime factorization is the process of finding the factors of a number and these factors must be of prime numbers.

27000 = 27 × 10000
27000 = 27 × 10⁴
27000 = 3 × 9 × 10⁴ [Here we have 3 as a prime number, but not '9' and '10', so we will keep breaking this down]
27000 = 3 ×3 × 3 × (2 × 5) ⁴ [Here we have all prime numbers]
27000 = 3³ × 2⁴ × 5⁴

Can anyone please tell me what I’m doing wrong. It’s not giving me the full marks. The marks for this question is 4 but I only g
Gekata [30.6K]

Answer:

33%

Step-by-step explanation:

The area of the entire circle:

The radius is 4+3+3 = 10

Area of a circle= pi * r^2


Area of largest circle      = pi * 10^2 = 100 pi


Area of blue ring = Area of blue circle - area of inner white circle

The blue circle has a radius of (4+3) = 7

The inner white circle had a radius of 4

Substituting what we know

Area of blue ring = Area of blue circle - area of inner white circle

                               = pi * r^2 - pi*r^2

                               = pi * 7^2 - pi *4^2

                                = 49pi - 16pi

                                = 33 pi


The percentage of the logo that is blue is the blue ring/ area of largest circle

percentage = 33 pi/100 pi

Canceling pi

percentage = 33/100

                    = 33 %

Colin buys a car for £28100.
andriy [413]

Answer:

The amount the car will be worth after 6 years is £21,917 and 22 pence

Step-by-step explanation:

The amount for which Colin buys the car, PV = £28,100

The amount by which the car depreciates each year, r = 4%

The number of years after which the value of the car is sought, n = 6 years

The future value, FV, based on an annual depreciation is given as follows;

FV = PV \times \left ( 1 + \dfrac{r}{100} \right ) ^n

Substituting the known values gives;

FV_6 = 28,000 \times \left ( 1 - \dfrac{4}{100} \right ) ^6 =  21,917.22

Therefore, the amount the car will be worth after 6 years, future value FV₆ = £21,917 and 22 pence
