Answer:

\sf C=21.99~ft.

__________

\sf Steps

  • \sf Given~the~diameter~is~7~ft...
  • \sf We~know~we~must~use~diameter-to-circumference~formula

         \sf Formula:  \pi d = \pi  * (diameter) = [Circumference]

__________

\sf Solve

\pi * 7 = 21.99~ft.

Jeff's mother gave him money. he used an equal amount of money each day. at the end of the 7th day, he was left with 1/4 of how
skelet666 [1.2K]

Jeff received 280$ from his mother

Such questions are the simplest as it needs you to just write the conditions accordingly which then simplifies and provides you the answer.

This question can be solved using two tricks which are shown below:-

Trick  1 :

1 – 1/4 = 3/4 (used for the 1st 7 days)

1/4 – 410 (used for 8th and 9th days)

(3/4)/7 ——- (1/4 – 10)/2

(3/4) x (2/7) = 3/14 ——- (1/4 – 10)

1/4 – 3/14 = (7 – 6)/28 = 1/28 ——- 10

28/28 ——- 10 x 28 =$ 280

Trick 2 :

7 days ——- 3/4

1 day ——- 3/28

2 days ——- 6/28

6/28 ——- (1/4 – 10) = 7/28 – 410

1/28 ——- 10

28/28 ——- 10 x 28 = $280

Thus Jeff received 280$ from his mother.

Answer:

28 . 26cm

Step-by-step explanation:

First find the radius

d = 2r \\ 9 = 2r \\  \frac{9}{2}  =  \frac{2r}{2}  \\ r = 4.5

Now find the CIRCUMFERENCE

c = 2\pi \: r \\  = 2 \times \pi \times 4.5 \\  = 9 \times \pi \\  = 28.26

Pls answer “b” correctly and I will mark it has brainlist
Phoenix [80]
Since it is a slope, the equation of a slope is y=Mx+b. So you want to get b to that format. To do this, you need to isolate the y on the left. To do this, you simply add 2x to both sides. Your final answer will be y=2x+7. Hope this helps!
