Answer:

Option B. a = 42, b = 5, c = 28, d = 33, e = 10.

Step-by-step explanation:

From the table it is given that total of Bikers who like touring bike and who do not love touring bike are 80 (last row).

So 70 + e = 80

e = 80 - 70 = 10

Now Bikers who don't like touring bikes are 10 (column 2)

Bikers who do not like touring bikes = Number of bikers who love mountain bikes + Number of bikers who do not love mountain bikes

10 = b + 5

b = 5

In first row

Bikers who like mountain bikes = number of bikers who like touring bikes + number of bikers who do not like touring bikes

a + b = 47

a + 5 = 47

a = 42

And now from column number 1.

a + c = 70

42 + c = 70

c = 70 - 42 = 28

From column 3

47 + d = 80

d = 80 - 47 = 33

Finally the values are a = 42, b = 5, c = 28, d = 33 and e = 10.

Option B. is the answer.

Kamau is now 2 years older than Jane if James age is y now what will be the total age in 10 years​
cluponka [151]

Answer:

(2y + 22) years

Step-by-step explanation:

kamau is now 2 years older than Jane if Janes age is y now what will be the total age in 10 years​.

Answer: If Jane is y years old now and Kamau is 2 years older than Jane, therefore the age of Kamau now would be 2 + y years.

In ten years time Jane age would be y + 10 years while the age of Kamau would be y + 2 + 10 = y + 12 years.

To get their total age we just have to add their individual age. Therefore the total age in 10 years​  = Age of Kamau in ten years + age of Jane in ten years = (y + 12) + (y + 10) = y + 12 + y + 10 = y + y + 12 + 10 = 2y + 22 years

What is the approximate volume of the sphere​
NISA [10]

Answer:

523.33 mm³

Step-by-step explanation:

The general formula for the volume of a sphere is:

V = \frac{4}{3}\pi r^{3}

The radius for the given sphere is 5mm, so plugging that value into the equation and using 3.14 for π:

V = \frac{4}{3}(3.14)(5^{3})

V ≈ 523.33 mm³

In ΔJKL, j = 93 cm, k = 82 cm and l=86 cm. Find the measure of ∠J to the nearest degree.
zhuklara [117]

Answer:

5

Step-by-step explanation:

Answer:

85t

Step-by-step explanation:

1. Volume of a cone: 1. V = (1/3)πr2h 2. Slant height of a cone: 1. s = √(r2 + h2) 3. Lateral surface area of a cone: 1. L = πrs = πr√(r2 + h2) 4. Base surface area of a cone (a circle): 1. B = πr2 5. Total surface area of a cone: 1. A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))

hope this helps
