A school paid $45.00 for 8 toothbrushes and 4 tubes of toothpaste. If each tube of toothpaste cost $4.50, how much did each toot

11111nata11111 [884]

Answer:

$3.38

Step-by-step explanation:

The formula is 45= 8x + 4t. Each tube of toothpaste is 4.50, so times four is 18. So they spent 18 dollars on toothpaste, and the rest on toothbrushes. There are 27 dollars left, and 8 toothbrushes, so divide and each toothbrush is $3.375, or $3.38

22) The base of a lampshade is circular. The circumference of the base is 3 times the radius increased by 4.25 inches.

BARSIC [14]

Answer:

~1.29 inches

Step-by-step explanation:

C = 2πr

C = 3r + 4.25

2πr = 3r + 4.25

2πr - 3r = 4.25

r(2π-3) = 4.25

r = 4.25/(2π-3) ≈ 1.29

The period of a pendulum is the time the pendulum takes to swing back and forth. The function L=0.81t^2 relates the length L in

Andreyy89

Answer: Period = 13.15 s

Solution:

The period of a pendulum is the time of pendulum takes to swing back and forth.

Function $L=0.81t^2$

Where,

L is length of pendulum in feet

T is time of pendulum in seconds

We have to calculate the time of pendulum whose length is 140 feet.

So, we substitute L=140 into formula $L=0.81t^2$ and to solve for t

We get t,

$140=0.81t^2$

$t^2=\frac{140}{0.81}$

$t=\sqrt{172.84}$

$t=13.15$ s

Period = 13.15 s
