Ralph is 3 times as old as Sara. In 6 years, Ralph will be only twice as old as Sara will be then.Find Ralph's age now.

Answers

R = 3S

R + 6 = 2 (S+6)

Substitute the first equation in the second one:

(3S) + 6 = 2 (S + 6)

3S + 6 = 2S + 12

S + 6 = 12

R = 18
S = 6

Check:

R is 3 times S now.

In 6 years, R will be (18 + 6) = 24, S will be (6 + 6) = 12.

24 = 2 x 12 yay

What isthe nth term in the sequece 1 3 5 7 9

Answers

If you add 2 the answer is 11, because
1+2 = 3 and 3+2 = 5 and 5+2 = 7
I hope this helps

or you could....

15 would be the ninth term in this sequence , because you have

1 3 5 7 9 11 13 15

skip every other number like 1 skip 2 , you have 3 skip 4 , you have 5 , skip 6

i hope this helps? :)

Which transformations are needed to change the parent cosine function to y= 3cos(10(x-pi) )?

Answers

The parent cosine function can be transformed and translated. So, from the basic function cos(x) we can obtain function acos(bx+c). In our case, a=3- amplitude, b=10- the period change and c=-pi- the phase shift. So, the parent cosine function is mutiplied with 3 (which gives the amplitude of the function, 3*0.5=1.5). The period of the function is changed, and is 2pi/b=2pi/10=pi/5 and the cos(x) is phase shifted for c/b=-pi/10.

Answer:

= 3 3/4 m^2

or 15/4 m^2

Step-by-step explanation:

The base is the triangle.

A =1/2 bh

A = 1/2 (3 1/3 * 9/4)

Change 3 1/3 to an improper fraction (3*3+1)/3 = 10/3

A = 1/2 * 10/3 *9/4

Re arranging

= 1/2* 9/3 * 10/4

= 1/2 (3) 5/2

=15/4

Now writing as a mixed number

= 3 3/4 m^2
