Answer:

to solve this we do the oppisite of multiplication which is division

so 84 divided by 12 = 7 so that means that our mysterious k = 7

so reprhase  the sentence so  '' The product of 12 and 7 is 84

hope this helps:)

Answer:

K=7

Step-by-step explanation:

The equation is 12 x k = 84 but we need to change the equation to find k

The opposite of multiplying is dividing so you can reverse 12 x k = 84 to 84/12=k

Solve

84/12=7

K=7

So I have to compute the following but i don't know what they mean any help?
Gelneren [198K]

Answer:

Step-by-step explanation:

This is a Combination (as in permutation vs combination) question the symbol (n r) refers to "n choose r". This is sometimes written as nCr

i.e the question is asking you to find how many combinations each will yield when you chose r items from n item without repetition and order does not matter.

I will only do the first question for you and you can just follow the same steps to solve the rest of the questions.

Recall that

nCr=\frac{n!}{(r!)(n-r)!}

Consider question a) we are given (5 1) or ₅C₁

we can see that n = 5 and r = 1

If we substitute this into the formula:

₅C₁ = (5!) / [ (1!)(5- 1)!]

= (5!) / [ (5- 1)!]

= (5!) / (4!)

= (5·4·3·2·1) / (4·3·2·1)

= 5

hence ₅C₁ = 5

If a cone with a diameter of 10 m has a surface area of 190.6m2, find its slant height. Round to the nearest tenth.
alukav5142 [94]

Answer:  The slant height of the cone is 65.6 m

Step-by-step explanation:

Given: The diameter of a cone = 10 m

Surface area of cone = 190.6 m²

To find: Slant height

Diameter of cone = 10 m

Therefore Radius of cone = \dfrac{\text {Diameter }}{2} = \dfrac{10}{2} =5m

As we know that surface area of a cone is given by

S.A. = \pi r(l+r)

Where S.A. is surface area , r is the radius of cone and l is the slant height of the cone.

Let Slant height = l

So we have

190.6 = \dfrac{22}{7} \times 5 ( 5+l)\\\\\Rightarrow  5+l= \dfrac{190.6 \times 7}{22}\\\\\Rightarrow l=  \dfrac{1334.2}{22}+5\approx 60.64+5 = 65.64\approx65.6

Hence the slant height of the cone is 65.6 m

The value of y varies directly with x. If x = 16 when y = 20, find the value of y when x = 60?​
son4ous [18]

Answer:

<h2>y = 75 when x = 60</h2>

Step-by-step explanation:

To solve this, we will use a proportion, since x and y vary directly with each other.

16 / 20 = 60 / y

<h2>Step 1: Cross-Multiply</h2>

16y = 1200

<h2>Step 2: Divide both sides by 16</h2>

16y / 16 = 1200 / 16

y = 75

<h2>Step 3: Check</h2>

16 / 20 = 60 / 75

1200 = 1200 ✅

<h2>y = 75 when x = 60</h2>
