Given:
2 pythons : 6 ft each
3 corn snakes : same length
Total length = 21 ft.

Let x be the length of one corn snake.

2(6ft) + 3x = 21 ft
12ft + 3x = 21 ft
3x = 21 ft - 12 ft
3x = 9 ft
x = 9ft/3
x = 3ft

Each corn snake is 3 ft long.

3x + 12ft = 21ft

Write the sets of all possible factors and the sets of common factors of the pairs of numbers, then find their H.C.F. could you

abruzzese [7]

Answer:

a= 1,2,4 b= 1,2,3,6 c=1,2,4 d=1,2,5,10 e=1,2,3,4,6,12 H.C.F of all the pairs= 2

Step-by-step explanation:

Factors of:

a. 8=1,2,4,8

12=1,2,3,4,6,12.

common factor=1,2,4

b. 12=1,2,3,4,6,12

18=1,2,3,6,9,18

common factor=1,2,3,6

c. 16=1,2,4,16

24=1,2,3,4,6,8,12,24

common factor=1,2,4

d. 20=1,2,4,5,10,20

30=1,2,3,5,6,10,15,30

common factor=1,2,5,10

e. 24=1,2,3,4,6,8,12,24

36=1,2,3,4,6,9,12,18,36

common factor=1,2,3,4,6,12

HIGHEST COMMON FACTOR (H.C.F)=

The factor common to the whole pairs

which is 1 and 2

therefore 1 multiplied by 2 which is equal to 2

(and in Mathematics means multiplication)

A ball is thrown straight up from the roof of an 80-foot building and it's height is modeled by the h(t) = â17t2 + 68t + 80, whe

Rasek [7]

Answer:

t = 4

Step-by-step explanation:

Given that:

$h(t) = 17t^2 + 68t + 80$

When h(t) = 80, we have that:

$80 = -17t^2 + 68t + 80\\\\=> 0 = -17t^2 + 68t\\\\=> 17t^2 - 68t= 0\\\\=> 17t(t - 4) = 0\\\\=> t = 0, t = 4\\\\$

t = 0 represents when the ball has not been thrown at all, in its initial position.

t = 4 represents the time taken for the ball to hit the roof of the building on its way down.

Hence, our answer is t = 4. (t is in secs)

Five adult tickets and three child tickets for a movie costs £55. The cost of buying two adult tickets and three child tickets i

Allisa [31]

Answer:

adult £8
child £5

Step-by-step explanation:

If you look at the numbers you are given, you see that the first purchase has 3 more adult tickets than the second purchase, and its cost is £24 more. This means an adult ticket costs £24/3 = £8.

Two adult tickets will cost 2×£8 = £16, so three child tickets cost ...

£31 -16 = £15

Each child ticket is then £15/3 = £5.

An adult ticket costs £8; a child ticket costs £5.
