<h2>a) 16y</h2><h2>b) 8y</h2>

a) First, multiply the numbers 8 and 2, and we get 16.

Now, we have to multiply 16 and the algebraic notation “y”, we get the result of 16y.

<h3><u>Whenever you multiply the number(s) with algebraic notations, you need to multiply the number(s) and write the algebraic notation at the end.</u></h3>

<u></u>

b) Multiply the number 8 and the algebraic notation “y”, and we get the result 8y.

skelet666 [1.2K]

Step-by-step explanation:

2x+3y=23 2x+3.7=23 2×1 + 3×7 = 23

3y= 23 2×+21= 23 2 + 21 = 23

23÷3 = 7 2x= 23-21

y=7 2x= 2

x= 1

5x+3y=17 5×4+3y=17

5x=17+3 20+3y=17

5×=20 20=17+3y

14÷5 = 4 20=20+y

x=4 y=20-20

y=0

An open cone has a slant height of 5m and a curved surface area of 251, Find the radius of the circular base.What is the answer:
julia-pushkina [17]

Answer:

Radius of the cone = 16 m

Step-by-step explanation:

Slant height of the cone 'l' = 5 m

Curved surface area of the cone is represented by the formula,

Curved surface area = πrl

Here r = radius of the circular base of the cone

l = slant height of the cone

By putting the values in the formula,

251 = πrl

251 = πr(5)

r = \frac{251}{5\pi}

r = 15.979

r ≈ 16 m

Therefore, radius of the given cone will be 16 m.
