Answer:

224 cubes

Step-by-step explanation:

The volume of the cubes is 1/64. Because 1/4*1/4*1/4=1/64.

The volume of the prims is 14/4 because 7/4*2*1=14/4.

Take the 14/4 and divide it by 1/64.

Which equals 896/4 = 224

Hope that helped.

Write an equation for the nth term of the arithmetic sequence.

tresset_1 [31]

Answer:

Step-by-step explanation:

3, 9, 15, 21, ...

9-3 = 6; 15-9 = 6; 21-15 = 6 ⇒ d = 6

first term: a = 3

difference: d = 6

so the formula:

$a_n=a+d(n-1)\\\\a_n=69+6(n-1)\\\\a_n =3+6n-6\\\\\underline{a_n=6n-3}$

and:

$a_{50}=6\cdot50-3=300-3=297$

Dima020 [189]

Answer:

37.5 °C

Step-by-step explanation:

The temperature appears to be increasing linearly at the rate of 5 °C in 2 minutes, or 2.5 °C per minute.

1 minute after 4 minutes, when the temperature is 35 °C, we expect it to be 2.5 °C higher, or 37.5 °C.
