Genrish500 [490]
3/5 of the total responses expected = 87...
3/5x = 87
x = 87 / (3/5)
x = 87 * 5/3
x = 435/3
x = 145 <=== what was expected

Eight times a number increased by 9 exceeds 7 times the number by 15. Find the number.
Alborosie
Turn it into math terms bit by bit. let x be "a number"

8 times a number is 8×x

increased by 9 is +9

7 times a number is 7×x

exceeds is minus

by 15 is =15

now we put it together.

8 \times x + 9 - 7 \times x = 15
solve
8x + 9 - 7x = 15 \\ x + 9 = 15 \\ x = 6

Ronin kicks a ball over the gate of the first floor balcony. The function h(t)=-36t^2+288t+9 can be used to model the height of
ale4655 [162]

Answer: 4 seconds

Step-by-step explanation:

Given: The function h(t)=-36t^2+288t+9 can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet.

Differentiate the given function with respect to t , we get

h'(t)=-36(2)t+288=-72t+288

Put h'(t)=0

\Rightarrow\ -72t+288=0\Rightarrow\ t=\dfrac{288}{72}\\\\\Rightarrow\ t=4

Also, h''(t)=-72

By second derivative test, h(t) is maximum at t=4.

Hence, the time in Devon which the ball reaches it maximum height = 4 seconds

WILL GIVE BRAINLIEST write an equation for the nth term of the arithmetic sequence and find the 30th term 28, 25, 22, 19, ... (s
Fudgin [204]

Answer:

a_n = 31 - 3n\\\\a_{30}= 59

Step-by-step explanation:

Given Arithmetic sequence is:

28, 25, 22, 19, ...

a = 28, d = 25 - 28 = - 3,

nth term of an Arithmetic sequence is given as:

a_n = a + (n - 1) d\\

Plugging a = 28 & d = - 3 in the above equation, we find:

a_n = 28 + (n - 1) (-3)\\\\a_n = 28 - 3n +3\\\\\huge\purple {\boxed {a_n = 31 - 3n}} \\(This \:is \:the \:required \:equation) \\\\Plug \: n = 30, \: we \: find:\\\\a_{30}= 31 - 3 \times 30\\\\a_{30}= 31 - 90\\\\\huge\orange {\boxed {a_{30}= 59}} \\\\
