You are riding your bicycle to prepare for a race. it takes you 12 minutes to go 2.5 miles. what was your speed in miles per hou

kolbaska11 [484]

Answer:

12.5 miles per hour.

Step-by-step explanation:

There are 60 minutes in 1 hour so:

12 minutes = 12/60 = 1/5 of an hour.

So his speed in mph

= distance in miles / time in hours

= 2.5 / 1/5

= 2.5 * 5

= 12.5 miles per hour.

These two trapezoids are similar What is the correct way to complete the similarity statement?

pentagon [3]

Option A:

$\mathrm{ABCD} \sim \mathrm{GFHE}$

Solution:

ABCD and EGFH are two trapezoids.

To determine the correct way to tell the two trapezoids are similar.

Option A: $\mathrm{ABCD} \sim \mathrm{GFHE}$

AB = GF (side)

BC = FH (side)

CD = HE (side)

DA = EG (side)

So, $\mathrm{ABCD} \sim \mathrm{GFHE}$ is the correct way to complete the statement.

Option B: $\mathrm{ABCD} \sim \mathrm{EGFH}$

In the given image length of AB ≠ EG.

So, $\mathrm{ABCD} \sim \mathrm{EGFH}$ is the not the correct way to complete the statement.

Option C: $\mathrm{ABCD} \sim \mathrm{FHEG}$

In the given image length of AB ≠ FH.

So, $\mathrm{ABCD} \sim \mathrm{FHEG}$ is the not the correct way to complete the statement.

Option D: $\mathrm{ABCD} \sim \mathrm{HEGF}$

In the given image length of AB ≠ HE.

So, $\mathrm{ABCD} \sim \mathrm{HEGF}$ is the not the correct way to complete the statement.

Hence, $\mathrm{ABCD} \sim \mathrm{GFHE}$ is the correct way to complete the statement.

Julli [10]

Evaluate them
A.
f(5), x>1 so square it, f(5)=25
A is wrong

B.f(2), x>1 so square it, f(5)=4
B is correct

C. f(1), x=1 so the result is 5, f(1)=5
C is correct

D. f(-2), x<1 so double it, f(-2)=-4
D is wrong

answers are B and C
