Answer:

56.52

Step-by-step explanation:

Circumference is $C=2\pi r$

We are given the radius of 9 in.

Using 3.14 for pi:

$C=2 * 3.14 *9\\\\C=6.28*9\\\\\boxed{C=56.52}$

The circumference of the circle should be 56.52 inches, your answer should be correct.

Miss penny inherits £650. She decides to save some of the money and spend the rest. The ratio of saving to spending money is 9:4

blsea [12.9K]

Answer:

Saving=£450

Spent=£200

Step-by-step explanation:

Ratio of saving to spending is 9:4

She inherits £650

So to determine her saving

It will be

9+4=13

Since her saving is 9

So, 9/13 × 650

5850/13

=450

So her saving is£450

To determine what she spent

4/13 × 650

2600/13

200

Saving=£450

Spent=£200

The given congruency of the sides $\mathbf{\overline{BE}}$ and $\mathbf{\overline{LO}}$ and $\mathbf{\overline{BO}}$ and $\mathbf{\overline{LE}}$ as well

as the congruency of the common side $\mathbf{\overline{BL}}$ gives.

ΔBEL ≅ ΔLOB by SSS congruency postulate

<h3>Which values correctly completes the table?</h3>

The completed two column proof is presented as follows;

Statement ${}$ Reasons

1. $\underline{\overline{BE} \cong \overline{LO}}$ ${}$ 1. Given

2. $\overline{BO}$ ≅ $\overline{LE}$ ${}$ 2.

4. ΔBEL ≅ ΔLOB ${}$ 4. <u>SSS congruency postulate</u>

Side-Side-Side, SSS, congruency postulate states that if three sides of

one triangle are congruent to three sides of another triangle, the two

triangles are congruent.

Four runners start at the same point; Lin, Elena, Diego, Andre. For each runner write a multiplication equation that describes t

Natalka [10]

Answer:

See the answers in the explanation

Step-by-step explanation:

Lin runs for 29 seconds at 7.2 meters per second. What is her finish point?

time= 29 seconds

speed= 7.2 m/s

distance= speed*time

distance= 7.2*29

distance=208.8 m

Elena runs for 26 seconds and finishes at 240 meters. What is her velocity?

time= 26 seconds

distance= 240meters

velocity= distance/time

velocity= 240/26

velocity=9.23 m/s

Diego runs for 33 seconds at -6.1 meters per second. What is his finish point?

time= 33 seconds

velocity

distance=velocity*time

distance=33*6.1

distance= 33*6.1

distance=201.3 m

Andre runs for 38 seconds and finishes at -295 meters. What is his velocity?

time= 38 seconds

distance= 295m

velocity= distance/tim

velocity= 295/38

velocity= 7.76m/s
