Answer:

1061.32 you made a typo on G

Step-by-step explanation:

To find the distance travelled by the tire we need the circumference of it

The formula for circumference is 2πr we know pi is roughly 3.14 and the radius is 13

we plug the numbers in and get

2* 3.14* 13

6.28*13

81.64

81.64 is the circumference, now we simply just multiply 81.64 by 13 to get 1061.32

Im guessing number G was supposed to be 1061.32 instead of 10,613

Answer:

C. 0.08889

Step-by-step explanation:

Total number of marbles:

5 + 2 + 1 + 2 = 10

There are two possibilities

Orange then green or green the orange

The probabilities are:

P(o&g) = 2/10*2/9 = 2/45
P(g&o) =2/10*2/9 = 2/45

Required probability is:

P = 2/45*2 = 4/45 = 0.08889

Correct choice is C

Pie

Answer:

1300 cm = 13 m

Step-by-step explanation:

We need to find meters in 1300 cm.

We know that,

1 m = 100 cm

1 cm = (1/100) m

It means,

$1300\ cm=\dfrac{1300}{100}\ m\\\\=13\ m$

Hence, there are 13 m in 1300 cm.

Answer:

Δ HGI ≅ ΔEDF

Step-by-step explanation:

Given:

Δ DEF ≅ Δ GHI

From the given congruence statement we can figure out the corresponding sides that are congruent.

The arrangement shows:

$D\rightarrow G\\E\rightarrow H\\F\rightarrow I$

So the rearranged statement can be written as:

ΔEDF ≅ Δ HGI

∴ Δ HGI ≅ ΔEDF
